Abstract

The invention relates to a double-sided printing machine, and relates to the technical field of printing machines. The double-sided printing machine comprises a box body and conveying rollers, wherein a printing device is arranged on the box body, and comprises two printing rollers, an ink coating mechanism and a driving mechanism, and the two printing rollers are rotatably arranged on the box body and are vertically arranged at an interval; and the ink coating mechanism is arranged on the box body and used for coating ink on the printing rollers, and the driving mechanism is arranged on the box body and drives the two printing rollers to rotate reversely. According to the invention, the two conveying rollers drive paper to move to the printing rollers, the ink coating mechanism coats the ink onto the two printing rollers, and the driving mechanism drives the two printing rollers to rotate to print the two sides of the paper, so that the two sides of the paper can be printed at the same time, and then energy and time used for paper printing are saved.

Description

technical field [0001] The present application relates to the technical field of printing machines, in particular to a duplex printing machine. Background technique [0002] A machine for printing text and images. Modern printing machines are generally composed of plate loading, ink application, embossing, and paper feeding (including folding). On the printing press, the ink is then applied manually or by the printing machine to the places where the text and images are on the printing plate, and then transferred directly or indirectly to paper or other substrates. [0003] In the related art, the printing machine includes a box body, a conveying roller, a printing roller, and an inking device. The paper is conveyed to the printing roller under the action of the conveying roller. The inking device applies ink to the printing roller, and the printing roller rotates to print the paper. After the printing is completed, it is output outside the box, so as to realize the printing...
