Straight-paper-path flexo printing machine

Abstract

The invention discloses a straight-paper-path flexo printing machine. The straight-paper-path flexo printing machine comprises a feeding unit, a printing unit, a drying unit and a receiving unit, wherein the feeding unit, the printing unit, the drying unit and the receiving unit are sequentially arranged on a straight paper path. The printing unit comprises a printing ink plate arranged on one side of the paper path, an ink feed roller arranged on the printing ink plate, an anilox roller tangential to the ink feed roller, a forme roller tangential to the anilox roller, and a printing roller which is arranged on the other side of the paper path and is tangential to the forme roller. Through the straight-paper-path flexo printing machine, paper exits from the feeding unit and enters the printing unit, the forme roller in the printing unit prints printing ink on the paper, and then the paper enters the drying unit to be dried and is output from the receiving unit. The feeding unit, the printing unit, the drying unit and the receiving unit are arranged in cooperation with the paper path, so that the paper path is approximately straight, and high-speed continuous printing of the paper can be guaranteed. The straight-paper-path flexo printing machine is suitable for small lists and middle and long lists.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a flat paper path flexographic printing machine. Background technique [0002] A printing machine is 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. [0003] The flexographic printing machine is a kind of printing machine. However, due to factors such as the structure of the printing unit and the needs of the drying system for the existing flexog...

Problems solved by technology

[0003] The flexographic printing machine is a kind of printing machine. However, due to factors such as the structure of the printing unit and the needs of the drying system for the existing flexographic printing machine with continuous operation of the paper path, the paper path between the two printing units is generally Going around and turning into a curved shape, the curved paper path has a longer operating paper path, which leads to more paper loss when the printing machine prints some expensive substrates or prints some smaller orders. Too much material used in the quasi-process makes the printing cost too high, and it cannot cope with the continuous high-speed printing of different repeated perimeters. Only the intermittent paper-feed printing method can be used. Compared with the continuous paper-feed printing method, its work efficiency is greatly reduced.
