Abstract
Description
Technical Field
[0001] This utility model relates to the field of release paper processing technology, and in particular to a release paper slitting device. Background Technology
[0002] Nowadays, when most items are packaged after processing, release paper is inserted to prevent adjacent items from sticking together, effectively ensuring that adjacent items do not stick together.
[0003] To save on the amount of release paper used, it needs to be cut according to the size and dimensions of the packaged items. In order to ensure the efficiency of the release paper cutting, it is usually unrolled and cut. However, release paper is generally a multi-layered structure. Common cutting methods use a guillotine-type cutting structure or a fixed blade cutting method. These two cutting methods are prone to delamination, curling, and edge curling at the cutting position. Therefore, a release paper cutting device is needed to ensure that delamination, curling, and edge curling are not easily caused during the cutting of release paper. Utility Model Content
