Description

Technical Field

[0001] The utility model relates to the technical field of label printing, and more specifically to a production and printing device for laser labels. Background Art

[0002] Laser labels generally refer to labels made using laser engraving or printing technology. These labels usually have high durability and clarity, and are suitable for occasions that require long-term use or use in harsh environments. Laser labels can be applied to various fields, including industrial production, product identification, safety identification, brand identification, etc. They usually have anti-counterfeiting features because the patterns or words engraved by laser are difficult to imitate or tamper with.

[0003] Existing production and printing devices for laser labels need to print adhesive on the back of the labels so that the laser labels can stick to the backing paper or the required items. However, the rollers used for applying the adhesive are generally of a fixed width, and the glue is brushed onto the surface of the roller by a brush. However, during the process of printing the glue on the roller onto the back of the label, the glue on the surface of the roller is easily squeezed out onto the laser surface of the label under the extrusion of the label, causing pollution, affecting the appearance, and being not conducive to sales. Summary of the Utility Model
