1. Overview

Shandong Lu Kang Food Packaging Machinery Co., ООО. is a professional manufacturer of vacuum packaging machines. The vacuum packaging machines produced include 400/2L, 400/2S, 700/2S, 800/2S, and CB-520, CB-420, CB-320 and other models, with dozens of varieties.

The CB series thermoforming vacuum packaging machine was developed by absorbing advanced world technology at the end of the last century. Its performance indicators are close to or exceed international advanced levels, making it a new type of fully automatic thermoforming vacuum packaging machine suitable for China’s national conditions. This machine is suitable for vacuum packaging of various meat products, овощи, фрукты, and other foods. Common models of this machine include CB-320, CB-420, CB-520, и т. д.. Special models can also be customized according to user requirements. The machine’s working process is as follows: bottom film stepping motion → bottom film heating and thermoforming → loading → covering top film → vacuuming and heat sealing → transverse cutting → longitudinal cutting → discharging. The entire process is automatically controlled by a programmable controller (ПЛК). The machine has a reasonable structure, is easy to adjust, and works reliably. Its production efficiency is very high, several times that of ordinary packaging machines. It can save labor and reduce production costs (its packaging cost is lower than using vacuum bags). The packaging effect is close-fitting, beautiful, transparent, and three-dimensional, which meets the packaging requirements of large supermarkets and is a must-have high-end equipment for large-scale enterprises.

2. Structure, Technical Features, Main Technical Data

1. Structure:

The main structure of the machine includes: frame, film clip chain, transmission mechanism, top film installation roller and top film idler roller, bottom film roller, bottom film idler roller, forming chamber, loading area, vacuum packaging chamber, cross-cutting knife, longitudinal cutting knife, pneumatic system, vacuum system, electrical control system, и т. д..

2. Technical Features:

1. Transmission System

   The bottom film moves forward under the clamping of the film clip chain equipped with film clips. The film clip chain realizes precise stepping movement under the drive of the frequency conversion (or servo) transmission system. The machine adopts foreign famous brand servo motors, programmable controllers (ПЛК) and touch screen automatic control, which are precise and reliable in control and simple to operate.

2. Forming Chamber

   The forming chamber consists of upper and lower working chambers and forming molds corresponding to the new products being packaged. The upper working chamber is fixed to the frame by bolts through guide posts. The upper working chamber moves up and down reciprocally under the drive of the cylinder. The upper working chamber is equipped with heating plates and thermal insulation boards. The forming heating temperature is controlled by a temperature controller (or temperature control module) and a thermocouple. The user can easily set the forming heating temperature on the temperature controller panel. The working process is that the lower working chamber first goes up to its upper limit position. After the upper and lower working chambers are completely sealed by the silicone sealing pad, the heating plate preheats the bottom film. Then the lower working chamber evacuates to generate a tensile force on the bottom film, sinking into the forming mold to become a geometric shape corresponding to the product to be packaged. The forming temperature varies depending on the quality, материал, thickness, hardness of the stretched film used. The reasonable forming temperature is determined by testing, generally around 90°C. The maximum drawing depth of this machine is about 80 мм. The required drawing depth is adjusted by the liner in the lower chamber during operation. According to user requirements, the forming mold can be customized.

3. Loading Area

   The products to be packaged are manually placed into the bottom mold cavity in the loading area. The loading area has a material carrier, which is selected and used according to the corresponding forming mold, which is very simple to insert and use.

4. Vacuum Packaging Chamber

   When the packaged product enters the packaging chamber driven by the bottom film, the top film is automatically covered, and vacuuming and heat sealing are completed in the vacuum packaging chamber.

   The vacuum packaging chamber consists of upper and lower working chambers. The upper working chamber is equipped with heating plates and airbags. The airbag inflation pressure is between 0.05 and 0.2Mpa, and the maximum should not exceed 0.25Mpa, otherwise the airbag and electric heating plate will be damaged. Vacuum chamber working process: When the packaged material enters the working chamber, the lower working chamber rises to the upper limit position under the drive of the cylinder and is sealed into one with the upper chamber. Then the air in the packaging cavity is extracted by the vacuum system, and the heating plate is driven downward by the airbag inflation to heat and seal the sealing area. The sealing temperature is generally around 130°C. In order to prevent the packaging film from sticking to the heating plate, the heating surface of the heating plate is coated with a non-stick plastic coating. If the heating plate temperature is too high or other improper operation causes it to stick to packaging film plastic dirt, и т. д., it should be checked regularly and carefully wiped off with a soft object or soft cotton cloth at a certain temperature (about 100°C). Sharp objects are strictly prohibited to prevent damage to the non-stick coating.

5. Cross-Cutting Knife

   The machine adopts punch-cutting for transverse cutting of the packaging film, and is generally equipped with 4 cross-cutting knives. The cross-cutting knife consists of upper and lower knives. The upper knife is a toothed knife die, and the lower knife is a serrated blade, which coincides with the upper knife die. The lower knife is driven upward by a cylinder, and the lateral clearance between the upper and lower knives should be reasonable (see the instructions later for adjustment). The four cross-cutting knives are controlled by pneumatic valves, ПЛК, and touch screen. If there are several rows of products in the left and right direction in one pitch or in one working chamber, then select several rows of knives on the touch screen. Например, if it is one row of products, select “one row of knives” on the touch screen, and if it is two rows of products, select “two rows of knives”, and if it is three rows of products, select “three rows of knives”……Then the “ПЛК” will automatically select the required cross-cutting knives among the 4 cross-cutting knives.

6. Longitudinal Cutting Knife

   The machine’s longitudinal cutting knife adopts a rotary cutting knife. The longitudinal cutting knife also consists of upper and lower knives. The upper knife is a high-speed rotating circular blade, and the lower knife is made of aluminum alloy. The lateral clearance between the upper and lower knives should be reasonable to prevent damage to the blade and affect the cutting effect. The number of longitudinal cutting knives is determined by the mold used. There are several sealing lines, and several knives are used.

7. Vacuum System

   The machine’s vacuum system consists of a vacuum pump, pneumatic vacuum valve, vacuum pipeline, and joints. The machine uses a German original imported “vacuum packaging machine special pump”. According to user requirements, a vacuum pump with a pumping rate of 100m3/h—300m3/h can be equipped. In order to improve the intake cleanliness of the vacuum pump and extend the service life of the vacuum pump, the machine is equipped with an intake filter, which needs to be cleaned regularly to prevent it from blocking and reducing the pumping rate of the vacuum pump.

8. Pneumatic System

   Most of the actions of the machine’s forming lower chamber, vacuum lower chamber, cross-cutting lower knife, high-pressure sealing, top film braking, and date printing are realized by solenoid valves, цилиндры, and compressed air systems. Поэтому, users are required to have a compressed air station or a spare air compressor with a supply volume of not less than 0.5m3/min. In order to ensure the long-term safe and normal operation of the equipment, the user’s compressed air pipeline system must be equipped with a matching oil-water separator. Note that the oil-water separator equipped by the user and the oil-water separator installed on the machine must drain water every shift. Pay more attention to this point in humid working environments, and increase the number of water drains if necessary.

9. Electrical System

   The machine uses 50HZ, 380V three-phase five-wire power supply, three-phase wire one neutral wire one ground wire. When the phase wire neutral wire is connected to the machine, it should correspond one-to-one. The neutral wire and the phase wire cannot be connected incorrectly. After careful verification, the machine can be powered on, otherwise the 220V electrical appliances of the machine will be burned out by high voltage! Pay attention to this point, and then verify the forward and reverse rotation of the motor. Окончательно, after verifying that there is no error, the machine can be powered on and work normally. The main components used and the power supply mode are: The main controller PLC requires a DC 24V power supply, and the 24V DC power is supplied by the switching power supply in the electrical box. The stepping control system adopts foreign imported servo motors, which are precise, стабильный, and easy to operate.

   The human-machine interface adopts foreign famous brand touch screen, 24V DC power supply. Pay attention not to reverse the “+” и “-” terminals of the 24V DC power input end during maintenance, otherwise it may cause damage to the touch screen. Adjustment of parameters on the touch screen: The vacuuming time can be adjusted arbitrarily according to needs, generally 3-15 seconds. The preheating time is generally set to 3-6 seconds. The stretching time is 2 seconds. The venting time is generally not less than 1.0 second. When adjusting the touch screen, do not use too much force. Только “touch” it to prevent damage to the screen and cause major losses (the touch screen is expensive electronic equipment).

   Heating temperature control part: Electric heating plates are installed in the forming chamber and vacuum chamber respectively, 220V AC single-phase power supply, and built-in thermocouples. The temperature controller is “OMRON” temperature control module, and the temperature display and control are simple, convenient, and intuitive on the touch screen.

   There is a safety switch under the cross-cutting knife cover of the machine. The power supply is low-voltage 24V DC. When the knife cover is not installed or the installation position is incorrect, it cannot move, and the machine cannot work, so as to play a safety protection role, which can prevent accidentally putting hands under the knife and avoid personal injury accidents. Поэтому, users must not arbitrarily change this function or accidentally introduce high-voltage electricity into the electrical box through the switch, which will damage electronic equipment using 24V power and cause damage to the machine.

3. Main Technical Parameters

III. Working Parts, Use, Replacement and Adjustment of Wearing Parts

1. Replacement of Molds in Forming Chamber and Vacuum Chamber

1. Lower the lower chamber of the working chamber (forming chamber and vacuum chamber) to the lower limit position.
2. Remove the mold and mold pad from the lower chamber by hand.
3. Place the required mold and pad corresponding to the required drawing depth.

Note: There are special pads at the suction hole positions in the lower chamber, do not use them wrong to prevent the suction holes from being blocked, causing failure to stretch or incomplete stretching!

2. Replacement of Electric Heating Plate and Thermocouple

1. Adjust the air source pressure to 0.2MP, and manually raise the vacuum chamber to the highest point (open the rear hood to find the pneumatic solenoid valve of the vacuum chamber, which has a red manual button), and then turn off the air source.
2. Unscrew the bolts that fix the forming chamber/vacuum chamber to the frame.
3. Remove the 220V electric heating plate power cord, thermocouple wiring and air circuit pipeline.
4. Remove and turn over the upper forming chamber. Just open the top cover of the vacuum chamber.
5. Carefully and carefully replace the damaged thermocouple or electric heating plate.
6. Connect the wires and fix the working chamber. Окончательно, reset the vacuum upper chamber and install the hood.

3. Adjustment of Cross-Cutting Knife and Replacement of Lower Blade

1. If serious burrs occur in the cross-cut, there are two reasons: one is that the lower blade is damaged, such as chipped or rolled edges; the other is that the lateral loosening of the upper and lower knives results in excessive clearance. If the cutting edge is damaged, it should be removed and re-sharpened, or replaced with a new knife. If the lower knife is loose, the lateral clearance between the lower knife and the upper film needs to be readjusted. Visually, it is about 0.05 мм (the cylinder is manually raised to the top at a low pressure of about 0.2Mpa, and the blade can be visually inspected after inserting into the upper knife). Окончательно, tighten the fixing bolts, and test by moving the air cylinder manually at a pressure of no more than 0.05Mpa to ensure that there are no errors before putting it into use.
2. The cut is not in the center of the seal.

   This phenomenon is mostly caused by the offset caused by the loosening of the cross-cutting knife fixing nut. You need to re-center and adjust the corresponding packaging seal, and then tighten the fixing nut.

4. Adjustment of Longitudinal Cutting Knife

If the longitudinal cutting knife cannot cut or burrs occur, the reasons are: (1) The blade edge is passivated or the edge is rolled and chipped, and it needs to be removed for repair or replacement; (2) The clearance between the upper and lower knives is too large, the fixing screw of the blade holder should be loosened, adjust the clearance to about 0.3-0.1 мм, and then tighten the fixing screw.

5. Adjustment of Film Clip Chain and Replacement of Film Clips

After the machine has been used for a period of time, the chain may become loose, causing the film clip opening to be too small to clamp the film or the film clip to fall off, and it needs to be adjusted and replaced in time.

1. Adjustment of tension

   There are chain tensioning bolts on the right side of the machine. Use a wrench to evenly turn the bolts on both sides clockwise for a few turns to tension the chain, but do not tighten it too much to prevent damage to the chain and related parts. If this adjustment cannot meet the tension requirements, you can remove a chain link from the chain joint.

2. Replacement of film clips

   If there are damaged film clips, they should be removed and new ones installed in time. If the number is small, you can directly replace them with pointed pliers without disassembling the chain on the machine.

6. Installation and Adjustment of Bottom Film Roll and Top Film Roll

The top film roll and bottom film roll are manually installed on the bottom film roll shaft and top film roll shaft respectively, and are clamped between the two baffles at the lower end of the film pressing link. The installation direction of the top film is generally counterclockwise to the winding direction of the film roll, and the bottom film is clockwise (see attached picture). When you start working with a new bundle of film, pay attention to whether the film runs off and causes the bottom film to be clamped unevenly on both sides of the film clip chain or one side is not clamped, causing the work to be unable to proceed or the top film completely covers the lower vacuum chamber, causing no vacuum. At this time, the front and rear positions of the film roll need to be adjusted. The method is: on the support beam of the link above the top film, there is a fine adjustment handle at the far right of the frame, which is used to fine-tune the film’s deflection. When the handle is swung clockwise, the film roll moves towards the rear of the machine, and vice versa, it moves towards the front of the machine. Slowly adjust until the working requirements are met.

7. Sealing Strip (Sealing Silicone Pad)

If you find that the sealing is not good, or the vacuum degree is not good for unknown reasons, or the forming is not good, you should check whether the sealing strip is damaged or aging, or the joint is not tight, and the gap is too large. If it is damaged, it needs to be replaced in time. If the joint is too large, it should be reinstalled, or the joint should be bonded and sealed with high-quality silicone.

8. Photoelectric Positioning System and its Use and Adjustment

The photoelectric positioning system consists of a photoelectric switch, a pressure regulating valve, a pneumatic solenoid valve, and a brake, and is controlled by a “ПЛК”. When using color-printed cover film, it is used to position the color film so that it accurately corresponds to the bottom film and does not run off. Otherwise, the pattern will be offset on the packaging, which will not meet the requirements for use.

Color film use principle: The bottom film moves forward accurately in a stepping manner under system control. The corresponding color cover film, without being controlled, gradually shifts away from the packaging center after a period of time due to its own stretching and the accuracy of printing, making it unusable. Поэтому, the movement of the color film must be controlled. If a color mark is printed on the center line of every two adjacent working positions on the color film (this machine uses a 14×6mm black color mark), when the photoelectric switch detects this color mark, the braking system brakes and positions the cover film, and is controlled by the “ПЛК” to synchronize with the bottom film movement, so that the packaging requirements can be met. The machine has a pitch of 394mm, and the color mark printing distance is between 392-393.5mm, printed on the sealing strip in the middle of each adjacent pitch. The attached picture below shows the color mark printing positions for 9 packages with a pitch length of 394 мм.

[Image: Color mark printing positions]

Photoelectric Positioning System Use Adjustment Steps:

1. After starting the machine, open the electrical box door, find the solenoid valve and pressure regulating valve combination that controls the brake, and press the red manual button on the solenoid valve to check whether the system air circuit is connected properly and whether the brake action is sensitive. At the same time, adjust the pressure reducing valve to a working air pressure of about 0.25Mpa.
2. Install the color film roll, and route the color film around the guide rollers on the electrical box to the front of the working chamber. Install the bottom film, and the machine starts to work. When the formed bottom film steps to 2 pitches before the vacuum working chamber, turn the “Work/Stop” switch to the stop position to allow the machine to stop running automatically.
3. Pull out the color film for at least one more pitch length, and cover it flat on the bottom film, and align the “sealing strip” printed with the color mark with the sealing position on the front pitch line of the bottom film, and then fix the front end of the color film and the bottom film together with tape.
4. Turn the “Work/Stop” switch to the “Work” position to allow the cover film and bottom film to naturally enter the vacuum chamber together, and then turn the switch to the “Stop” position to stop the machine from running. Then move the film roll by hand to make the pulled film in a natural tension state.
5. Touch the “Color Film Selection” button on the control screen, the indicator light is on, and then adjust the position of the photoelectric switch to make the focal point of the emitted light illuminate about 5mm above the center of the color film “color mark”, and make the end face of the switch emitting light about 10mm away from the color film. For the specific use method, please refer to the attached color mark photoelectric switch manual.
6. After the above adjustments are completed, you can enter experimental operation. During the working process, observe whether the brake pad acts as required, and whether the color mark of the packaged finished product is in the center position of the seal. When starting to work, the color mark may not be in the center position of the seal, or it may be left or right. You must readjust the upper and lower positions of the photoelectric switch to correct the deviation. The method is: if the color mark position is biased to the left, appropriately adjust the switch position upwards by a few millimeters, and vice versa, lower it by a few millimeters until the packaging requirements are met. After the adjustment is completed, fix the switch position, and then you can enter normal work. During the working process, do not allow the color film to vibrate, and sticking it to the light barrier can solve this problem.

Note: During the working process, pay attention not to touch the color film to prevent the photoelectric switch from malfunctioning, which may lead to the failure of the color film being pulled off. When you don’t use color film and switch to light film, adjust the touch screen to the “Light Film Selection” state. (Note: The focal point walking route of the photoelectric switch, that is, the color of the sealing area must be a single color.

CB Series Thermoforming Vacuum Packaging Machine Basic Operation Steps

1. First check the lubrication condition of each moving part of the machine (pay attention to adding oil and lubricating regularly, and add oil once every 5 days as needed), then turn on the power, and turn on the air source to check whether the air pressure reaches the rated pressure (0.6MPA). If the product needs to be inflated, check whether the inflation air source is connected properly and whether the pressure meets the requirements.
2. Start the vacuum pump on the touch screen, and open “Status Monitoring” to check whether the “Safety Switch” и “Emergency Stop” switches are in a normal state.
3. Turn the “Work/Stop” switch to the “Work” position to test run to check whether each working part is normal.
4. Turn off the “Air Source” и “Источник питания” again, and select the appropriate mold and mold depth, bracket, and tool (longitudinal knife) according to product requirements.
5. Install the upper film (counterclockwise) and the bottom film (clockwise), turn on the power and air source and cooling water (there is water flowing out), and use the “jog” switch to move the bottom film into the “forming chamber”.
6. When the temperature (forming temperature, vacuum heat sealing temperature) rises to the required value, select the cross-cutting knife corresponding to the product and the appropriate vacuum time, and start the vacuum pump (vacuum heat sealing 110℃—150℃, forming: 70℃—110℃).
7. After the above work is done, you can turn the “Work/Stop” switch to the “Work” position for trial operation, and check the bias and correction of the bottom film in time.
8. When the formed bottom film steps to the
