1. The machine of the trademark laminating machine does not start: the input wire is blocked, the power wire 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 air 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 of the heating box is leaking, the distribution box is leaking, the external wire is tied to the equipment, and the motor is leaking.

Fifth, the film suction of the trademark laminating machine is not in place: insufficient vacuum, air leakage, insufficient temperature, film too thin, workpiece pasted with other materials, the depth of the workpiece exceeds the film lift, the suction time is too short, the film is not stretched Rise, the workpiece is too close.
