Rotary laminating machine is to apply plastic adhesive to the plastic film and print it with paper as the substrate, and then press the rubber roller and heating roller to form a product of paper and plastic. The printed product coated by the laminating machine has a 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 product, but also prolongs the service life of the printed product. To waterproof, anti-fouling, wear-resistant, fold-resistant, chemical corrosion and other protective effects.
        1. The rotary laminator 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 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.
        5. The film is not in place: the vacuum is not enough, air leakage, temperature is not enough, the film is too thin, the workpiece is 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, the workpiece distance Too close.
        6. The surface of the overlaid workpiece has folds and is 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.

        8. Breaking phenomenon: the temperature is too high, the heating time is too long, the film quality is not good, and there is no heating.
