A transparent roller for laser embossing and a laser embossing device

Abstract

The invention discloses a transparent roller for laser imprinting. The transparent roller comprises a roller body, a roller hub and a roller shaft. The roller body comprises a quartz glass transparent roller and a plastic transparent roller which is arranged on the quartz glass transparent roller in a sleeved mode and is not in contact with the quartz glass transparent roller. The quartz glass transparent roller and the plastic transparent roller are driven in a synchronous mode through a servo motor. The transparent roller is provided with at least one mother set with an engraved laser pattern. The transparent roller further comprises a shading layer which is arranged above the plastic transparent roller. A light transmitting pattern of the shading layer is matched with the laser pattern of the mother set. Correspondingly, the invention discloses a laser imprinting device used for the transparent roller. Point-to-point location special set pattern imprinting transferring can be achieved, the fringing phenomenon of four sides of a transferred pattern is removed, imprinting transferring pattern accuracy is improved, and pattern surface quality is improved.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a transparent roller for laser embossing and a laser embossing device. Background technique [0002] At present, the laser pattern making method is realized by coating, molding (high temperature, high pressure), or made into a laser film, and then the laser effect is realized on the printing material by means of transfer, hot stamping, cold stamping, etc. The specific process route is as follows: [0003] One of the traditional laser pattern imprinting transfer production processes: the process steps are in order of selecting a specific film such as PET → coating a release agent on the film → molding graphics on the release layer at high temperature and high pressure → making a laser film → on the laser film Glue application→composite the laser film and printing material→peel off the laser film→transfer the graphic and laser texture layer to the printing material. ...

AI Technical Summary

Problems solved by technology

However, the traditional laser pattern imprint transfer needs to use high temperature and high pressure to complete the production of laser film first, and then use film-to-film transfer, which leads to the following disadvantages: 1. Long process route, low precision, low efficiency and high cost ; 2. Only the laser embossing transfer of continuous general laser patterns can be carried out; 3. The shadow problem is caused by lamination and overflowing glue around the laser pattern, and the surface quality of the laser positioning embossing transfer pattern is not high
