Common faults and elimination of automatic laminating machine:
1. Horizontal wrinkles. This is due to the fact that the longitudinal tensile force of the mulch is less than the lateral tensile force, and the forward speed is uneven.
Solution: reduce the pressure of the left and right pressure film wheels; increase the clamping force of the film roll; the unit's forward speed should be uniform and consistent.
2. Longitudinal wrinkles. This is due to the fact that the longitudinal tensile force of the mulch film is greater than the lateral tensile force.
Solution: increase the pressure of the left and right pressure film wheels; reduce the clamping force of the film roll; appropriately reduce the forward speed of the unit.
3. Diagonal wrinkles. The reason is that the unit failed to drive straight, or the pressure of the left and right pressure wheel is not consistent.
Solution: Improve the operation technical level and make the unit run straight; adjust the two pressure film wheels to make the pressure even and consistent.
4. Deflected mulch. It is caused by the failure of the unit to drive in a straight line, or the installation of the film roll is not correct, and the film roll itself is not properly wound.
Solution: Realign the film roll to the front side and perpendicular to the direction of advance of the unit; the unit should travel at a uniform speed and straight line; check the film roll and replace it if necessary.
5. The film pressing wheel can't hold the mulch. This is due to the reasons that the unit is not running properly, the width of the film is not matched with the border surface, and the quality of the film itself is not good. It should be solved according to the specific situation.
6. After the film is spread, the curling and both sides are broken. For the occurrence of curling, the pressure of the film pressing wheel should be increased, the deflection angle of the soil shovel should be reduced, and the distance between the soil shovel and the mulch film should be adjusted. If the film breaks, the pressure of the two pressure film wheels should be reduced, and the quality of the land preparation should be checked.

Self-adhesive film laminating machine manufacturers introduced that we often see self-adhesive products in life, so what kind of adhesive is used for self-adhesive? In fact, the glue used for stickers is the adhesive.
Adhesive refers to an adhesive that is sensitive to pressure and only needs to use contact pressure to glue two different materials together. Apply the adhesive to thin flexible substrates such as paper base, cloth base or plastic to make adhesive products such as labels, tapes and films. Mainly used for packaging, office, vehicles, building finishing, protection, metal, plastic, etc.
The self-adhesive film laminating machine manufacturer stated that the pressure-sensitive adhesive tape is the most convenient to use, and therefore has developed the fastest. The pressure-sensitive adhesive tape is composed of pressure-sensitive adhesive, primer, base material, back-side treatment agent and release paper. What kind of glue is used for stickers? Pressure-sensitive adhesive is the most important part of the adhesive. It must have good adhesion between the adhesive tape and the adherend under external pressure.
The pressure-sensitive adhesive base material used for adhesives of adhesive laminating machine manufacturers is the basis for supporting pressure-sensitive adhesives. It requires good mechanical strength and small elasticity. It has good wettability to solvents, etc. Fabric, paper tape and plastic film.
What are the safe operation procedures and precautions for the operation of the adhesive laminator?
The self-adhesive film laminating machine is a mechanical device that divides a wide PVC film into multiple narrow materials. When operating the slitting machine, you should pay attention to the safe operation process:

3. Open the pneumatic shut-off valve (set on the air intake pipe under the pneumatic control cabinet) to check whether the air pressure is correct (not less than 6.0bar) and stable.
2. Setting control
1. Set the cutting menu according to the type, thickness, length, width, etc. of the PVC film arranged in the cutting plan.
2. Lift the corresponding PVC film file from the PDF.
3. Set the winding length and width of the film with corresponding specifications.
4. Select the corresponding winding station, adjust the roller arm and roller, and install the paper core of corresponding specifications.
3. Feeding, film passing and film joining
1. Feeding: According to the requirements of the cutting plan, according to the driving operation regulations, according to the actual situation, hang the corresponding parent roll on the aging frame, choose the direction according to the inside and outside of the corona surface, and place it on the cutting machine unwinding frame, and use The control button clamps the steel core, leaving the steel core support arm and driving.
2. Film penetration: When there is no film on the slitter, film penetration is required. Use the slitting device and function keys of the slitting machine to tie one end of the original film to the eye of the film linking chain, and activate the filming button so that the film is evenly distributed on each roller along the slitting process.
3. Membrane connection: When there is membrane on the slitting machine, when changing the roll joint, use the vacuum membrane table to start the membrane connection table to the working position, manually flatten the film on the first traction roller of the slitter and start the upper vacuum pump Suction the film to make the film flat to be adsorbed on the film receiving table, attach double-sided tape and cut off the excess film under the tape, flatten the film on the unwinding rack and start the lower vacuum pump to make the film flat to adsorb, remove the tape Put on the paper layer and level the adhesive film. The joints should be neat and wrinkle-free. Then turn off the upper and lower vacuum pumps, and open the film receiving table to the inoperative position.

Laminating is to apply a plastic film with an adhesive, and then combine it with a paper-based printed matter, pressurized by a rubber roller and a heated roller, and form a paper-plastic product. The use of automatic laminating machine will inevitably encounter failures. Next, the editor will teach you several common troubleshooting methods for automatic laminating machine.
Automatic laminating machine: common troubleshooting method for laminating machine
1. The machine does not start: the input wire is disconnected, the power cord is reversed, and the voltage is insufficient.
2. Inaccurate temperature measurement: thermocouple, temperature controller. Whether the installation is incorrect and damaged.
3. The working vacuum does not come up: the gas path is blocked, the hand valve or solenoid valve is not closed, the vacuum pump motor belt is loose, and the vacuum gauge is damaged.
4. The main power switch trips: leakage of input wires on the top of the heating box, leakage of the distribution box, external wires on the equipment, leakage of the motor, etc.
Fifth, the suction film is not in place: the vacuum is not enough, the air leakage, the temperature is not enough, the film is too thin, the workpiece is pasted with other materials, the concave depth of the workpiece exceeds the lift of the film, the suction time is too short, the film is not lifted, the distance between the workpiece Too close.
Sixth, the surface of the overlaid workpiece is folded and not smooth or the corners cannot be wrapped: the film is not straightened, the quality of the film is not good, the workpiece is not well polished, the glue is sprayed too much, and the mold below the workpiece is too low. 7. The film is pulled down when the suction is not reached: whether the solenoid valve or hand valve is open.
7. Breaking phenomenon: the temperature is too high, the heating time is too long, the film quality is not good, and there is no heating.
Eight, bad sticking situation
1. Improper selection of adhesive, improper setting of glue amount, incorrect proportioning measurement. The type and amount of adhesive should be reselected.
2. The diluent contains alcohol and water that consume NCO groups, so that the hydroxyl group of the main agent does not react. High-purity ethyl acetate should be used.
3. There is powder spraying on the surface of the printed matter. Wipe gently with a dry cloth.
4. The ink layer of the printed matter is too thick. The adhesive coating arrangement should be increased to increase the pressure.
5. The ink layer of the printed matter is not dry or completely dried. It should be hot pressed once before gluing; choose adhesives with high solid content; increase the thickness of the adhesive coating; increase the temperature of the drying tunnel.
6. The adhesive is absorbed by the printing ink and paper, which makes the coating amount insufficient. Should re-formulate and set the coating amount.
7. The surface treatment of plastic film is not enough or exceeds the applicable period, which makes the treatment surface invalid. The plastic film of the laminator should be replaced.
8. The pressure is low, the speed is fast, and the temperature is low. The temperature and pressure of the film should be increased, and the vehicle speed should be appropriately reduced.
9. Foaming
Ten, film wrinkle
1. The film transfer roller is unbalanced. The transfer stick should be adjusted.
2. The ends of the film are inconsistent or wavy. Qualified film should be replaced.
3. The adhesive layer is too thick, the solvent is not evaporated completely, which affects the viscosity. When pressed by the pressure roller, there is a slip between the paper and the film. The amount of glue should be adjusted to increase the temperature of the drying tunnel.
4. Both ends of the electric heating roller and the rubber roller are unbalanced, the pressure is inconsistent, and the linear speed is not equal. Two rollers should be adjusted.
