[0002] Self-adhesive label material, also known as self-adhesive label material, is a composite material made of paper, film, or specialty materials, with an adhesive coating on the back and a silicone-coated protective paper as the backing. During daily production, printed labels need to be laser cut and the waste label paper surrounding each individual label removed.
[0003] However, when separating waste, the tension of the roll label paper cannot be changed, and it may be too loose or too tight at times, which may cause the roll to be too loose or broken. When discharging waste, the waste collection roll needs to be frequently replaced, but each replacement is time-consuming and laborious, and the production progress is greatly slowed down. In addition, due to the stickiness of the glue, some labels may be rolled up, and adhesion and deformation may occur during storage. For this reason, we propose a waste discharge device for a label printing machine. Utility Model Content
