[0002] Self-adhesive labels have the advantages of no need to apply glue, paste, or water, no pollution, and save labeling time compared to traditional labels. They have a wide range of applications and are convenient and fast. Self-adhesive labels are a kind of material, also called self-adhesive label material, which is a composite material with paper, film or other special materials as the surface, adhesive on the back, and silicone-coated protective paper as the base paper. After printing, die-cutting and other processing, they become finished labels.

After a long period of die-cutting of self-adhesive labels, the blade of the existing die-cutting knife may be worn, thereby affecting the cutting efficiency and needing to be replaced. The existing die-cutting knife is usually installed on the knife holder with a fixed structure, which makes it troublesome to disassemble and assemble the die-cutting knife and the disassembly and assembly efficiency is low. Therefore, a self-adhesive label die-cutting machine is proposed to address the above problems. Utility Model Content
