First, the size error
The dimensional error refers to the deviation of the longitudinal dimension of the bag.
cause:
1. The bag length of the bag making mechanism is too large.
2. The electric eye tracking is not allowed.
3, the impact of plastic composite film bag processing speed.
4. Operational factors, such as improper tension control, insufficient pressure setting of the rubber roller of the film rubber roller.
Solution:
1. Adjust the fixed length system.
2. Adjust the working state of the electric eye.
3. Check for cursor printing problems or spacing problems and adjust them.
4. Check whether the compression degree of the pressed film strip and the friction coefficient of the composite film are appropriate.
5, pre-adjusted film length and actual bag size should be as accurate as possible.
6. Reduce the bag making speed, and the adjustment of the bag making speed should be carried out slowly.
7. Adjust the pressure of the rubber roller, the cylinder pressure and the pressure of each part.
Second, the upper and lower films are not allowed
The problem that the upper and lower sheets are not aligned when the front and back sides are not aligned.
cause:
1. The composite film is uneven in thickness and has a lotus leaf edge.
2. The tension of the double floating roller is too small.
3. Some rollers do not rotate smoothly.
Solution:
1. Adjust the tension of the double floating roller.
2. Check and adjust the relevant guide rollers (such as compensation roller, deflection roller, etc.).
