Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label technology, specifically to a multi-roller coating device for self-adhesive labels. Background Technology

[0002] Self-adhesive labels have advantages over traditional labels, such as no need for glue, paste, or water, no pollution, and saving labeling time. They have a wide range of applications and are convenient and quick. Self-adhesive labels are a type of material, also called self-adhesive label material. They are composite materials with paper, film or other special materials as the face stock, adhesive on the back, and silicone-coated release paper as the backing paper. After printing, die-cutting and other processing, they become finished labels. During the processing, coating equipment is usually used to coat the self-adhesive labels.

[0003] Authorization announcement number CN215612733U discloses a self-adhesive label coating device, including a base box. The upper surface of the base box has a groove, and four sliding rods are installed within the groove. A float plate is slidably mounted on the outer side of each sliding rod. The surface of the float plate has at least one hole. Connecting rods are installed between adjacent sliding rods, and an adhesive roller is rotatably mounted between the connecting rods. The advantages are: the float plate keeps the adhesive roller close to the surface of the self-adhesive label, ensuring that the self-adhesive is evenly applied to the bottom surface of the label after it slides over the adhesive roller and the float plate. Furthermore, the sliding connection between the rotating shaft and the sliding groove allows for adjustment of the distance between the roller and the scraper roller, controlling the thickness of the self-adhesive and resulting in better performance.

[0004] In the above technical solution, the floating plate is used to keep the coating roller close to the surface of the self-adhesive. However, during long-term use, since the coating roller is always immersed in the inside of the self-adhesive, the self-adhesive on its outer surface may harden, which will affect the normal operation of the coating process.
