Printing unit structure capable of replacing adhered and hung printing offset plate under non-stop condition

Abstract

The invention discloses a printing device which can be used for ensuring a printing unit which does not need to be subjected to plate replacement to continuously work (non stop) and can also be used for replacing an adhered and hung printing offset plate for a printing unit which is not used for printing so as to improve the utilization rate of equipment and the production efficiency. The printing device comprises a rack, a printing roller, an inking roller and an impressing roller. The printing roller is respectively laminated with the inking roller and the impressing roller. A lifting device is arranged on the rack. Both the inking roller and the printing roller are arranged on the lifting device. A printing registration servo motor is arranged on a device for driving the printing roller to rotate.

Description

Technical field:

[0001] The invention relates to a printing unit structure for replacing stuck printing offset plates without stopping the machine. Background technique:

[0002] In cardboard printing, the printing plate needs to be replaced or cleaned due to processing different orders or equipment maintenance, but the existing technology of cardboard printing consists of multiple sets of The printing unit is composed of the embossing roller and the printing roller are driven by the same gear transmission chain, and they cannot rotate independently. When replacing, maintaining and cleaning the printing plate, the whole machine needs to be stopped. When a cardboard printing equipment is configured There are multiple printing units, and it is necessary to change or clean several sets of printing units configured, and it is impossible to realize the original technology when the printing units that do not change the plate or clean are expected to continue to work. Technology c...
