Paper uniform feeding device for printing machine

Abstract

The invention discloses a paper uniform feeding device for a printing machine. The paper uniform feeding device for the printing machine comprises a base, supporting tables, first sliding parts, a second guide rod, an export assembly, a first guide rod and a mounting rod, wherein a shell is arranged on the base; a feeding hole and a paper outlet hole are formed in the shell; power devices used fordriving the supporting tables to move up and down are arranged at the lower end of the supporting tables at the inner bottom surface of the shell; a placing plate is arranged in a mounting groove atthe upper ends of the supporting tables, and clamping centering assemblies are arranged on the supporting tables at the two sides of the mounting groove; two ends of the first guide rod are connectedwith the shell in a sliding manner; a second sliding part which is connected with the first guide rod in a sliding way is provided with a mounting cylinder; the mounting rod is connected with a mounting frame and a third sliding part in the mounting cylinder; the mounting rod is sleeved with a spring; a pressure sensor is arranged between the third sliding part and the inner wall of the mounting cylinder; the mounting frame is provided with a press roller; and the export assembly for uniformly conveying paper from the paper outlet hole to the printing machine is arranged on the second guide rod. According to the paper uniform feeding device, the paper can be positioned, and the paper can be uniformly conveyed at the same height.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a paper uniform feeding device for printing machines. Background technique [0002] A printing machine is a mechanical device that presses the inked surface on the media surface to form an image. It is generally composed of plate loading, ink application, embossing, paper feeding and other mechanisms. It first makes the text and image to be printed into a printing plate , loaded on a printing press, and then transferred to paper or other substrates to reproduce the same print as the printing plate. In the paper printing process, it is necessary to use a paper feeding device to transport the paper into the printing machine; the existing paper feeding device for the printing machine will cause the paper to shift during the paper feeding process, which will affect the printing quality, and will drop onto the paper The dust and debris on the surface will seriously affect the printi...

Problems solved by technology

In the paper printing process, it is necessary to use a paper feeding device to transport the paper into the printing machine; the existing paper feeding device for the printing machine will cause the paper to shift during the paper feeding process, which will affect the printing quality, and the paper will fall to the paper The dust and debris on the surface will seriously affect the printing quality; the stacked paper will gradually decrease during the uniform conveying process, and it is necessary to control the export component used to export the paper to move down to absorb the paper and return the paper to the printing machine after returning to the original position, increasing the export Increased energy consumption for moving distances of components
