What are the common failures and removal of vacuum laminator?
Vacuum laminating machine is widely used, whether it is packaging or printing, the finishing press of the product needs the help of vacuum laminating machine. In the vacuum laminating machine work, it will inevitably encounter some problems, below, let Xiaobian to introduce you vacuum laminating machine common faults, so that operators can find in time, timely maintenance.
1., suction phenomenon: the temperature is too high, heating time is too long, the film quality is not good, no heating.
2., suction film is not in place: vacuum is not enough, gas leakage, temperature is not enough, the film is too thin, the workpiece has been affixed to other materials, the workpiece more than the concave depth of the film pulled up, the suction time is too short, the film did not pull up, the distance from the workpiece too close.
3., did not smoke when the film down to pull up: solenoid valve or hand valve is open?.

2., suction film is not in place: vacuum is not enough, gas leakage, temperature is not enough, the film is too thin, the workpiece has been affixed to other materials, the workpiece more than the concave depth of the film pulled up, the suction time is too short, the film did not pull up, the distance from the workpiece too close.
3., did not smoke when the film down to pull up: solenoid valve or hand valve is open?.
4., the surface of the workpiece is folded and not smooth or angular package: the film is not straightened, the quality of the film is not good, the workpiece is not polished well, glue spray too much, the lower part of the template is too low.
5. the machine does not start: the input line is blocked, the power line is connected, and the voltage is not enough;
6., temperature measurement is not accurate: thermocouple, thermostat, whether the installation error or damage;
7., the work vacuum does not come: gas road closed, hand valve or solenoid valve is not closed, vacuum pumps, motor belts loose, vacuum table damage.
