Problems solved by technology

[0004] Yet the defective that this kind conventional gravure printing machine exists is:
[0005] First, when printing, the ink not only enters the fine depressions of the printing plate cylinder, but also forms on the cylinder around the depressions. In this way, in order to remove the ink located around the depressions on the cylinder, it is necessary to manually remove the above depressions before transferring. removed before entering the ...

Abstract

The invention provides a photogravure press, a coating roller of which is made of rubber to ensure that the coating roller is respectively in flexible contact with an absorbing roller and a to-be-printed steel plate, and thus the tightness of the contact is ensured, a pattern region on the absorbing roller can be completely transferred on the coating roller, and a pattern region on the coating roller also can be completely transferred to the to-be-printed steel plate, therefore a complete pattern region is formed. In addition, the photogravure press provided by the invention comprises a first scraper and a second scraper, wherein the first scraper is used for scraping a coating on the absorbing roller, except for a pit for forming an image region, the second scraper is used for removing residual coating on a rubber roller after transferring, therefore, the defects of lower labor efficiency and poor control precision caused by manual removal of the coating are avoided, and thus the labor productivity is increased and the product quality is ensured. In addition, the first scraper and the second scraper are respectively in contact with the absorbing roller and the coating roller by a specific angle, and thus a better scraping effect can be ensured.

Description

technical field [0001] The invention relates to a gravure printing machine, in particular to a gravure printing machine used for the production of color steel plates, belonging to the field of color steel plate forming. Background technique [0002] The traditional method of forming a color layer on a steel plate is generally to use spraying or heat transfer printing for painting. However, the color layer painted by spraying or heat transfer printing often has poor formability in the later stage, and it is very difficult in the bending process. It is easy to cause the color layer to fall off from the steel plate, and the production efficiency is extremely low. Later, after a lot of research, people used the gravure printing technology traditionally used for paper to produce color steel plates. [0003] A conventional gravure printing machine mainly includes a printing plate cylinder, an ink supply cylinder and an impression cylinder. It is opposite to and in contact with t...
