Abstract

The invention provides a double-sided printing device. The double-sided printing device comprises a separation device, a first conveying device, a first printing device, a combination device, a secondconveying device and a second printing device, wherein a printing roller of the first printing device is arranged in a reverse rotation manner; a printing roller of the second conveying device is arranged in a positive rotation manner; the separation device is used for stripping base paper of a wide sheet from surface paper; the first conveying device is used for conveying the surface paper to the first printing device to be printed; the combination device is used for combining the printed surface paper with the base paper to prepare a combined wide sheet; the combined wide sheet is conveyedto the second printing device through the second conveying device. The auto-rotation direction of a first driving roller of the first printing device is opposite to that of a second driving roller ofthe second printing device; and moreover, the conveying directions of the surface paper and the wide sheet can be changed through the first conveying device and the second conveying device, so that double-sided printing on the wide sheet can be achieved.

Description

technical field [0001] The present invention relates to the technical field of printing devices, in particular to a duplex printing device. Background technique [0002] A printing press is a mechanical device that presses the inked side against the media (such as paper and cloth) to form an image. It was first invented by German Gutenberg in 1440. Modern printing machines are generally composed of plate loading, ink application, embossing, paper feeding (including folding) and other mechanisms. Its working principle is: first make the printing plate of the text and image to be printed, install it on the printing machine, and then apply the ink to the place where the text and image are on the printing plate manually or by the printing machine, and then transfer it directly or indirectly Print onto paper or other substrates such as textiles, sheet metal, plastic, leather, wood, glass, and ceramics to reproduce the same print as the printing plate. The invention and develop...
