Laminating machine repair and maintenance
1. The machine does not start: the input wire is blocked, the power wire is reversed, and the voltage is not enough.
2. Inaccurate temperature measurement: thermocouple, temperature controller. Whether it is installed incorrectly or 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 tripped: the input wires on the top of the heating box leaked, the distribution box leaked, the external wires were connected to the equipment, and the motor leaked.
5. Inadequate suction film: insufficient vacuum, air leakage, insufficient temperature, too thin film, workpiece pasted on other materials, depth of the workpiece exceeds the lift of the film, suction time is too short, the film is not pulled up, the distance between the workpiece too close.
6. The surface of the covered 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 well, too much glue is sprayed, and the touch plate under the workpiece is too low.
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.
