Description

Technical Field

[0001] The utility model relates to the technical field of self-adhesive label printing, in particular to a printing roller for self-adhesive label printing. Background Art

[0002] Self-adhesive labels have the advantages of no need to apply glue, paste, or water, no pollution, and save labeling time. They have a wide range of applications and are convenient and fast. Printing is a technology that transfers the ink of text, pictures, photos, anti-counterfeiting manuscripts to the surface of paper, textiles, plastics, leather, PVC, PC and other materials through plate making, inking, and pressurization to copy the original content in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink.

[0003] The existing printing roller is not convenient for disassembling and assembling the outer cylinder, so that when the outer cylinder is damaged, it is not convenient to disassemble and replace it. The printing roller can only be replaced as a whole, which increases the maintenance cost. It is not convenient to protect the surface of the outer cylinder, so that the surface of the outer cylinder is easily corroded by printing ink and becomes uneven, affecting the printing effect. In addition, the existing printing roller is usually fixedly connected by bearings, which is not convenient for disassembly and assembly, so that a lot of time is needed to dismantle it for maintenance and repair, which is inconvenient to use. Therefore, the utility model provides a printing roller for printing self-adhesive labels. Utility Model Content
