Laminating machine manufacturers analyze the rapid elimination of laminating machines:
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 the 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 the input wire on the top of the heating box, leakage of the distribution box, external wires on the equipment, leakage of the motor, etc.
Fifth, the laminating machine manufacturer explained that 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 pull of the film, the suction time is too short, the film is not Pull up, the workpiece is 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.
8. Laminating machine manufacturers explain that the laminating machine has a bad sticking situation
1. Improper selection of adhesive, improper setting of glue amount, incorrect proportioning measurement. Should re-select the type and amount of adhesive.
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. Adhesive coating arrangement should be increased to increase pressure
5. The ink layer of the printed matter is not dry or completely dried. It should be hot pressed once before gluing; choose an adhesive with high solid content; increase the thickness of the adhesive coating; increase the temperature of the drying tunnel, etc.
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 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
1. The printing ink layer is not dry. It should be hot pressed again and then glued; postpone the coating time and let it dry completely.
2. The printing ink layer is too thick. Should increase the amount of adhesive coating, increase pressure and compound temperature.
3. The drying temperature is too high, and the surface of the adhesive skins. The drying temperature should be reduced
4. The surface temperature of the composite roller is too high. The temperature of the composite roller should be reduced.
5. The film is wrinkled or loose, and the film is uneven or curled. The film should be replaced and the tension adjusted.
6. There are dust impurities on the surface of the film. It should be cleared in time.
7. Uneven coating of adhesive and low dosage. The coating amount and uniformity should be improved.
8. The adhesive concentration is too high, the viscosity is large, and the coating is uneven. Use thinner to reduce adhesive concentration.
Ten. Wrinkle treatment of laminating machine manufacturers
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.
