A roller printing machine with gap work

Abstract

The invention discloses a cylinder press capable of working intermittently, and a printing method using the same. The cylinder press comprises a printing cylinder, paper feeding rolling shafts, paper brakes, a printing rolling shaft and an inking anilox roller, wherein two paper brakes are arranged at a paper inlet end and a paper outlet end respectively and corresponding to the rolling shafts; the inking anilox roller is provided with an ink scraper, and is arranged in cooperation with an ink pond; the printing rolling shaft and the inking anilox roller are arranged on the two sides of the printing cylinder respectively, and are matched with the printing cylinder; two paper feeding rolling shafts are the same in diameter, can linearly move in a reciprocating way, and drive paper to move linearly in a reciprocating way under the condition that the paper inlet end and the paper outlet end of the cylinder press are unmovable. During printing, paper does not need to move synchronously to a traction chain of a packaging machine at the same linear speed, independent electric control is adopted, and high printing efficiency and high quality are achieved.

Description

technical field [0001] The invention relates to the field of printing machines, in particular to a roller printing machine working in gaps. During printing, the paper does not need to move synchronously with the traction chain of the packaging machine at the same line speed, and is independently electrically controlled. It can realize online printing of high-efficiency and high-quality blister packaging machine or be used for individual printing occasions. Background technique [0002] At present, the forms of known online printing machines for packaging machines are divided into: flat printing machines and roller printing machines. The composition of the flatbed printing machine is as follows: figure 2 Shown: printing top plate (2-1), paper (2-2), inking cylinder (2-3), inking rubber roller (2-4), inking roller (2-5), ink pool ( 2-6), cylinder (2-7) and printing plate (comprising printing plate 2-8). Its working principle is that the traction of the paper (2-2) is realiz...

AI Technical Summary

Problems solved by technology

Due to the inertia of the large-diameter printing cylinder (3-1) with the printing plate, it cannot respond quickly, so that the moving speed of the packaging machine chain is restricted, thereby affecting the running speed of the packaging machine

In addition, to ensure the consistency of the moving speed of the packaging machine chain and the moving line speed of the printed text layout, the control of the servo motors driven by them must be related to the packaging machine, so this type of printing machine cannot be used as an independent product in other occasions
