Plastic film cover machine common faults and troubleshooting

1. Causes of horizontal wrinkle failure: This is due to the reason that the longitudinal tensile force of the film is less than the transverse tensile force, and the forward speed is not uniform. Solution: Reduce the pressure of the two left and right lamination rollers; increase the clamping force of the film roll; the forward speed of the unit should be uniform.

2. Causes of longitudinal wrinkle failure: This is due to the fact that the vertical tensile force of the plastic film is greater than the horizontal tensile force. Solution: Increase the pressure of the two left and right lamination rollers; reduce the clamping force of the film roll; properly reduce the forward speed of the unit.

3. Oblique wrinkle failure Cause: The reason is that the unit fails to drive straight when towing, or the pressure of the left and right diaphragm rolls is inconsistent. Solution: Improve the technical level of operation so that the unit goes straight; adjust the two lamination rollers so that the pressure is uniform.

4. Plastic film deflection Causes of failure: It is caused by the unit's failure to drive straight, or the film roll is not installed correctly, and the film roll itself is not wound properly. The solution: re-align the film roll, and with the unit forward direction; unit to uniform speed, straight line; check the film roll, replace if necessary.

5. The diaphragm can not hold down the pressure of the film Cause: This is due to the fact that the unit is not moving properly, the width of the film is not matched with the surface of the diaphragm, and the winding quality of the film itself is not good. It should be solved according to the specific situation.

6. After the film is rolled and both sides of the film are curled, the pressure of the lamination roller should be increased, the declination angle of the shovel blade should be reduced, and the distance between the shovel blade and the plastic film should be adjusted. In the event of membrane rupture, the pressure of the two lamination rollers should be reduced to check the quality of the site preparation.
