No matter when there are problems in a powerful system, after all, the system, like the human brain, will collapse at a certain time, which requires us to adjust and repair in time, so as to better lay a solid foundation for the following work. Today, Eternal Sheng Xiaobian briefly introduces the common faults and treatment methods of blister machines.

 Blister machineIt is a machine that heats and plasticized PVC, PE, PP, PET, HIPS and other thermoplastic plastic coils to be sucked into various shapes of advanced packaging and decoration boxes, frames and other products. Because of its stable performance, smooth operation, low energy consumption, low noise, etc., is widely used.

The 1. machine does not start: the input wire is blocked, the power cord is reversed, and the voltage is not enough;

2. temperature measurement is not accurate: thermocouple, temperature controller. Whether the installation is incorrect and damaged;

The working vacuum degree of the 3. cannot be reached: the gas circuit is blocked, the hand valve or solenoid valve is not closed, the belt of the vacuum pump motor is loose, and the vacuum gauge is damaged;

Trip of the main power switch of the 4.: leakage of the input wire on the top of the heating box, leakage of the distribution box, leakage of the external wire on the equipment, leakage of the motor, etc;

5. suction film is not in place: vacuum degree 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 pulling up of the film, the suction time is too short, the film is not pulled up, and the distance between the workpiece is too close;

The surface of the workpiece covered by the 6. is folded and not smooth or the corners cannot be covered: 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;

When the 7. does not reach the suction, the film is pulled down: whether the solenoid valve or hand valve is open;

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