What are the reasons for the misalignment of the paper cylinder of the paper cup machine? The paper cup machine is a professional manufacturer of paper cup machine and paper bowl machine. Let's introduce the reasons for the misalignment of the paper cylinder:
Cause of dislocation:
First, the paper material of the paper cup produced by the paper cup machine is not flat enough, and the operators do not put the paper sheets with pleats properly;
Second: the push rod of the paper cup machine fails and cannot work normally, thus causing the paper cylinder of the paper cup machine to be misaligned.
Dislocation solution:
First: the paper folding link of the paper cup machine is very important. If the paper is folded well, the paper dislocation will not occur frequently.
Second: when folding paper sheets, the paper sheets should be flat and well matched with the rising contact surface of the suction skin of the paper cup machine. Otherwise, the suction skin and the paper sheets do not have sufficient contact, which will lead to paper jam of the paper cup machine and a series of faults.
