Printing device of plate roller of multi-color gravure printing machine

Abstract

The invention discloses a printing device of a plate roller of a multi-color gravure printing machine, which is a main component part of the gravure printing machine. A closed container is arranged according to the size of the printing machine, the printing plate roller, a scraper and a water ink spray nozzle are arranged in the closed container, and a pressure pump with pressure is mounted outside the closed container and further connected with the water ink spray nozzle. One surface of the closed container is set to be a moving surface so as to facilitate the replacement of the plate roller. A feed port and a discharge port are formed on the closed container, a baiting valve is arranged at the bottom of the closed container and filtration is further performed. By the adoption of the printing plate roller, dry plate phenomenon happens hardly, and a printed pattern is clear; compared with the prior art, printing and color registration of the multi-color gravure printing machine are stable, the printing speed is further improved, the working efficiency is improved and the good printing effect is obtained.

Description

1. Technical field [0001] The invention relates to a printing device for a plate roller of a multi-color gravure printing machine. 2. Background technology [0002] At present, the printing and packaging industry in my country is the same as in foreign countries. An ink tank that is larger than the printing roller is set under the printing roller. The dots of objects fall off, the pattern is not clear, and the work efficiency is low, so the printing color registration stability is poor, the printing registration accuracy is low, the ink transfer is uneven, and the printing quality is affected to a certain extent. Therefore, the printing device of the plate roller of the multi-color gravure printing machine of the present invention makes the printing color registration stable, further increases the printing speed, improves the work efficiency, obtains good printing effect, and improves the disadvantages such as skinning, dry plate, and dirty plate. 3. Contents of the inventi...
