Self-adhesive labels are a composite material with paper, film or special materials as the surface, adhesive coated on the back, and silicone-coated protective paper as the base paper.
[0003] At present, the production process of self-adhesive labels requires steps such as design, plate making, printing, die-cutting, and quality inspection. Among them, die-cutting is a cutting process that can cut the printed self-adhesive labels according to pre-designed graphics.
[0004] The existing die-cutting device for producing self-adhesive labels does not press the self-adhesive labels during die-cutting, causing the self-adhesive labels to curl or bend, and the self-adhesive labels are easily attached to the bottom of the die-cutting knife, causing the self-adhesive labels to move when the die-cutting knife is retracted, causing the self-adhesive labels to shift and affect subsequent cutting.
