Offset printing device capable of preventing paper deformation and used for press and publication

Abstract

The invention discloses an offset printing device capable of preventing paper deformation and used for press and publication. The offset printing device capable of preventing paper deformation and used for press and publication comprises a device main body, an offset printing roll, an inking roll, a first cleaning roll, an air-drying box, a fan and a dustproof screen, wherein a base paper reel isarranged on the device main body, and a limit plate is installed at the outer side of the base paper reel; a base paper tape extends from the base paper reel, and a press roll and a guide-in roll areconnected to the outer side of the base paper tape; a fixed plate is arranged at the front side of the guide-in roll, and a tensioning roll is fixed to the inner side of the fixed plate; an auxiliaryoffset printing roll is arranged at the front side of the tensioning roll, and a main offset printing roll is connected to the outer side of the auxiliary offset printing roll; the air-drying box is installed at the front side of the auxiliary offset printing roll, and a guide-out roll is fixed to the front side of the air-drying box; and a support rod is installed on the device main body. According to the offset printing device capable of preventing paper deformation and used for press and publication, impurities left on the auxiliary offset printing roll can be cleaned through a second cleaning roll, and static electricity on the auxiliary offset printing roll can further be eliminated, so that the adverse effects of external dust on the auxiliary offset printing roll are avoided.

Description

technical field [0001] The invention relates to the technical field of news publishing, in particular to an offset printing device for news publishing that prevents paper deformation. Background technique [0002] At present, the press and publishing industry is very developed, and there are many kinds of newspapers and magazines. In the development of the news and publishing industry, some printing devices are indispensable. With the rapid development of the news and publishing industry, the printing devices are also being updated. Take the offset printing device as an example. Simply speaking, offset printing is a printing method in which the graphics on the printing plate are transferred to the substrate by means of a blanket, which can well compensate for the unevenness of the surface of the substrate, so that the ink can be fully transferred, thereby ensuring printing. quality. [0003] However, there are still some problems in the working process of some offset printi...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an offset printing device for press and publication that prevents paper deformation, so as to solve the problem that the current offset printing device proposed by the above-mentioned background technology is inconvenient to disassemble and assemble the offset printing roller, and cannot perform maintenance work on the device efficiently, and When some offset printing devices are working, the paper is prone to deformation during the transmission process, and thus the working quality of the offset printing device cannot be guaranteed
