Description

Technical Field

[0001] This utility model relates to the field of printing press technology, and in particular to an embossing device for printing presses. Background Technology

[0002] Printing is a technology that mass-produces original manuscripts such as text, pictures, photographs, and anti-counterfeiting materials by transferring ink to the surface of materials such as paper, textiles, plastics, and leather through processes such as plate making, inking, and pressing. Printing is the process of transferring approved printing plates onto a substrate using printing machinery and special inks. Embossing is a technique that uses molds with raised or recessed textures to deform the bearing material under pressure and temperature, creating patterns and artistically processing the surface of materials such as advertising posters.

[0003] In existing printing presses, during the long-term embossing process of advertising posters and other materials, impurities and dirt adhere to the surface of the embossing rollers, solidifying and becoming difficult to clean. The existing embossing rollers lack a brush cleaning structure to simultaneously clean their surface. Furthermore, the height of the embossing rollers is relatively fixed during the embossing process of advertising posters and other materials of varying thicknesses, failing to provide stable height adjustment for embossing materials of different thicknesses.

[0004] Therefore, an embossing device for printing presses is proposed. Utility Model Content
