First, there are many transfer guide rollers (feeding guide rollers):
Numerous guide rollers not only require flexible rotation, but also require good dynamic and static balance treatment. Imagine that if each guide roller gives a little resistance to the printed matter passing through, it is difficult to guarantee the accuracy of the printed matter due to the asynchronous resistance and static electricity generated during the printing of the printed film.
Secondly, it is the tension control part:
The unwinding part needs to be unrolled: the film roll has a large tension and the film roll has a small tension; the receiving part requires that the film roll has a small tension and the film roll has a large tension. That is, when the unwinding film is unwound, the tension should be small. As the film roll decreases, the tension gradually increases. When unwinding the receiving film, the tension should be small. As the film roll increases, the tension gradually increases.
When printing in a soft pack factory, the film should always maintain the same tension. Because the tension of the film is stable during unwinding, the tension of the receiving film is also stable, and the printed product will not run out of the plate to maintain the accuracy of the set.
