Abstract
Description
Technical Field
[0001] The present application relates to the technical field of plastic bag production, and in particular to an anti-curling plastic bag slitting machine. Background Art
[0002] Plastic bags are essential in our daily lives and are often used to hold other items. They are widely used due to their low cost, extremely light weight, large capacity, and ease of storage. However, plastic bag production requires cutting, which necessitates the use of a plastic bag slitting machine. However, when plastic bags are slitting, they can curl. This can cause overlap during the subsequent rewinding process, resulting in poor rewinding.
[0003] Most of the existing technologies do not pay attention to the curling problem during slitting, or only flatten the plastic bags after slitting. Before slitting, the plastic bags can be heated to make cutting smoother and reduce the occurrence of curling. Therefore, a plastic bag slitting machine with anti-curling is needed.
