A noise-absorbing green environmental protection gravure printing device

Abstract

The invention discloses a sound-absorbing green and environment-friendly gravure printing device, comprising an imaging base plate, a die, a surface light source and an ink plate. The light source emits UV light toward the ink plate, and the die is inserted between the ink plate and the surface light source from the side of the imaging base plate. When using, first coat a layer of UV ink on the surface of the ink board, and irradiate the surface light source below it upwards. Only the light consistent with the pattern on the die can pass through the die and irradiate the ink board. The ink board is transparent and the light can continue. The ink in the pattern area is semi-solidified into a colloid state, and then the liquid ink is removed to obtain the pattern to be printed, and the printed part is contacted with the upper surface of the ink board from top to bottom to complete the printing operation. The shape of the pattern is determined by the shape of the pattern vacancy of the die, so the printing requirements of different patterns can be met by changing the die, and the entire printing roller does not need to be replaced.

Description

Technical field [0001] The present invention relates to the field of printing technology, specifically a sound-cancelling green environmentally friendly gravure printing apparatus. Background [0002] Printing is the text, pictures, photos, anti-counterfeiting and other original manuscripts through the plate making, ink application, pressurization and other processes, so that the ink transfer to paper, textiles, plastic products, leather, PVC, PC and other materials surface, batch copy of the original content of the technology. [0003] Printing according to whether the printing plate is in direct contact with the substrate, printing can be divided into letterpress printing, gravure printing, screen printing, wherein gravure printing is: first scrape the excess ink on the printing plate, and then through the embossing rubber roller to the printing plate between the printed matter, with appropriate pressure, the ink from the concave surface to the printing material on a printing ...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, the gravure printing is to engrave the pattern on the printing roller, first fill the ink, then scrape off the ink on the surface, keep the ink in the pit, and then the printed matter contacts the printing plate to transfer the ink. Such printing technology pattern needs Engraving onto the print roll, changing the pattern requires replacing the entire print roll, which is cumbersome and expensive to replace
