How to deal with the common problems of laminating machine laminating machine?

Jan 26 2021

Laminating machine laminating is to coat a plastic film with an adhesive, and combine it with the printed matter with paper as the substrate, pressurized by a rubber cylinder and a heating cylinder, to form a paper-plastic product. The printed matter laminated by the laminating machine has an extra layer of thin and transparent plastic film on the surface, which makes the surface smoother and brighter, which not only improves the gloss and fastness of the printed matter, and prolongs the service life of the printed matter, but also the plastic film To protect against water, dirt, abrasion, folding, and chemical corrosion.

1. The laminating 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 of the laminating machine 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 of the laminating machine trips: the input wire of the heating box is leaking, the distribution box is leaking, the external wire is tied to the equipment, the motor is leaking, etc.

5. Film suction of the laminating machine is not in place: insufficient vacuum, air leakage, insufficient temperature, film too thin, workpiece pasted with other materials, the concave depth of the workpiece exceeds the film lift, the suction time is too short, the film does not lift , The workpiece is too close.

6. The surface of the overlaid workpiece is folded and not smooth or the corners cannot be wrapped: 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. When the film is not sucked up, the film is pulled up downwards: whether the solenoid valve or the hand valve is open.

8. 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.
