Abstract

The invention discloses a roll paper perfecting press. The roll paper perfecting press comprises a paper supplying device, an ink supplying device, a printing device and a paper collecting device; thepaper supplying device comprises a paper supplying roller, a paper supplying supporting seat and a paper supplying table; the paper collecting device comprises a paper collecting roller, a paper collecting supporting seat and a paper collecting table; the ink supplying device comprises an ink duct, an ink roller, a first ink conveying roller, a first inking roller, a second ink conveying roller and a second inking roller, and the ink roller is suspended in the middle of the ink duct; the printing device comprise a first plate roller, a first impression roller, a second plate roller and a second impression roller, and the upper portions of the first plate roller and the second plate roller are provided with ink scraping devices; and the upper portion of the paper collecting device is provided with a drying device. According to the roll paper perfecting press, compared with the prior art, one ink duct is provided and can provide ink for the printing device with two systems at the same time, turning operation does not need to be conducted on printed paper, and the roll paper perfecting press has the advantages of being simple in structure, convenient to operate, not prone to damagingthe printed paper, capable of saving printing ink and manpower and improving the printing quality, and the like.

Description

technical field [0001] The invention relates to the field of printing machines, in particular to a web double-sided printing machine. Background technique [0002] The printing machine is generally composed of plate loading, ink application, embossing, paper delivery and other mechanisms. The working principle of the printing machine is: firstly, the text and image to be printed are made into a printing plate, installed on the printing machine, and then manually or by the printing machine. The ink is applied to the text and image on the printing plate, and then directly or indirectly transferred to the paper, so as to reproduce the same printed matter as the printing plate. In the printing process, it is often necessary to print on both sides of the printing paper Printing, therefore, the traditional printing technology is to turn the printing paper over. The traditional double-sided printing machine is equipped with a surface-changing roller, which is driven by the motor to...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a web double-sided printing machine to solve the problem of the need to turn over the printing paper multiple times in the existing double-sided printing technology, the operation is cumbersome, and the structure of the printing machine It is complicated, and it is easy to damage the printing paper during the process of turning over the printing paper multiple times. The printing machine needs to set up two ink fountains or ink tanks to supply ink to the two sets of printing devices, which requires a lot of manpower and is easy to cause ink waste. , technical problems such as low printing quality
