In the production of plastic bag making machine, the plastic bag has wrinkle phenomenon, which will seriously affect the appearance and quality of the plastic bag products. If the problem is not solved properly, the sales of plastic bags will be involved later, which will seriously affect the image of enterprise brand in the long run. After the explanation by the bag-making machine operator, li chengfeng machinery editor made a summary and summary of relevant knowledge, the specific content is as follows:
There are six possible reasons for the wrinkling of plastic bags in the rubber roller of bag making machine.
1. The pressure of the middle rubber roller of bag making machine is not even, which needs to be observed and tested in detail.
2. Excessive dust on the rubber roller of bag making machine. In this case, you can use an air gun to carefully clean the roller.
3. The temperature of the back cover of the plastic bag is too high. Due to the physical reason of hot expansion, cold contraction and contraction of the plastic, it is likely that the back cover temperature is too high.
1. The mounting tilt of the film plate of the bag making machine leads to the non-parallel of the rubber roller on the surface of the bag making machine.
2. The back seal of the plastic bag after the bag making machine is not cool down. This problem is probably caused by the failure of the cooling device.
3. The pressure of the feeding floating roller is too high, and it needs to be tested to reach the standard pressure before it can run normally.
