Technical Field

The utility model relates to the technical field of printing machine feeding, in particular to a printing machine feeding device.

Background

A printer is a machine that prints text and images. Modern printers typically consist of mechanisms such as plate loading, inking, stamping, paper feeding (including folding). The working principle is that the characters and images to be printed are made into printing plate, then the printing plate is mounted on a printer, then the ink is applied on the place where the characters and images are on the printing plate by means of manual or printer, then directly or indirectly transferred on paper or other printing stock (such as textile, metal plate, plastic, leather, wood plate, glass and ceramic), so that the printed matter identical to the printing plate can be reproduced. The utility model and development of the printing machine play an important role in the spread of human civilization and culture.

In the existing printer, when printing paper boards, paper sheets, wood boards, metal boards and the like, the printer needs to manually lay stacked unprinted paper sheets and paper boards on a paper conveying mechanism one by one, and convey the unprinted paper sheets and paper boards to a next mechanism for printing through the paper conveying mechanism. Most of the existing printers can not automatically lay stacked unprinted paper and paperboards one by one, and convey materials to the printers at a constant speed. In view of this, we propose a feeding device for a printing press.
