The laminating process is a surface processing technology after printing, and it is also called post-printing plastic, post-printing glue or post-printing film. It refers to the use of a laminating machine to cover a layer of 0.012～0.020mm on the surface of the printed product. Thick transparent plastic film to form a paper-plastic integrated product processing technology.

Today we will talk about the maintenance of the laminating machine:

1. The machine does not start: the input wire is blocked, the power cord is connected reversely, and the voltage is not enough.

2. Inaccurate temperature measurement: thermocouple, temperature controller. Whether the installation is incorrect or damaged.

3. The working vacuum cannot be increased: 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 is tripped: the input wire on the top of the heating box is leaking, the distribution box is leaking, the external wires are tied to the equipment, and the motor is leaking.

5. Insufficient suction film: insufficient vacuum, air leakage, insufficient temperature, too thin film, workpiece pasted with other materials, the concave depth of the workpiece exceeds the film lift, the suction time is too short, the film is not lifted, and the distance between the workpieces Too close.

6. The surface of the overlaid workpiece is folded and not smooth or the corners are not covered: the film is not straightened, the film quality is not good, the workpiece is not polished, too much glue is sprayed, and the template under the workpiece is too low.

7. Play break phenomenon: the temperature is too high, the heating time is too long, the film quality is not good, and there is no heating.
