Problems solved by technology

[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 cannot improve the utilization rate of equipment and work efficiency

Embodiment Construction

[0013] Below in conjunction with accompanying drawing, the utility patent is further described.

[0014] In this embodiment, the printing unit structure for replacing the stuck printing offset plate without stopping the machine includes a frame 1, a printing roller 2, an inking roller 3 and an embossing roller 4, and the embossing roller 4 is installed on the frame 1 It cannot be moved up and down. The printing roller 2 is respectively pressed with the inking roller 3 and the embossing roller 4. There is a lifting device on the frame 1, and the inking roller 3 and the printing roller 2 are installed on the On the lifting device; the printing registration servo motor 21 is set on the device that drives the printing roller 2 to rotate, so that the printing roller 2 on the embossing unit that is lowered to the printing height rotates and registers the printing position on the cardboard, and the lifting device is controlled by the slide The block 5 and the lead screw 6 are compose...

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.
