What if the size of the plastic bag making machine's film delivery varies in the workflow?

Let me solve it now

During the working process, the film feeding size varies in length, with the feeding size being more than 5mm shorter than the pre adjusted size. There may be one intermittent non film feeding during the working process.

Handling method:

(1) The sensitivity adjustment of the photoelectric eye is not good or the polarity selection is incorrect.

(2) The photoelectric switch should be replaced due to ground leakage or short circuit between terminals.

(3) If the feeding speed is lower than the feeding speed, it is necessary to loosen the pressure film strips, check the performance of the feeding part, and troubleshoot.

Do you understand the handling method for plastic bag making machines that have varying film feeding sizes during operation, with the feeding size being more than 5mm shorter than the preset size, and there may be one intermittent non film feeding during the working process
