A feeding device for a printing machine

Abstract

The present invention relates to the technical field of printing machines, in particular to a feeding device for printing machines, comprising a frame, a printing assembly for printing is arranged on one side of the top end of the frame, and a concave The guide wheels of the shape structure, the outer walls of both sides of the frame are provided with moving grooves and telescopic grooves, the inner walls of the moving grooves are slidably connected with moving blocks, and the side walls of the moving blocks are threaded with locking bolts, so A part of the moving block is located outside the side wall of the frame, and the bottom end of the part of the moving block is movably connected with a return spring, and the inner wall of the telescopic groove is slidably connected with a slider, and one side of the slider is fixedly installed with a connecting pole. The present invention overcomes the deficiencies of the prior art. Through the provided telescopic slot, when not in use, the feeding roller can be removed, so that the supporting plate can be moved to the outside of the frame, so that the adjustment mechanism of the feeding roller can be conveniently stored. Simplify the storage of the entire feeding device and reduce its footprint.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a feeding device for printing machines. Background technique [0002] A machine for printing text and images, a modern printing machine generally consists of mechanisms such as plate loading, ink application, embossing, and paper feeding. 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 Printing onto paper or other substrate to reproduce the same print as the printing plate. [0003] After searching, the patent with publication number CN209259213U discloses a printing machine feeding mechanism, which includes a box body, a motor is fixedly connected to the top of the box body, and the output shaft of the motor penetrates into...
