A positioning device for a large-scale printing mechanism

Abstract

The invention discloses a positioning device of a large-size printing mechanism. The positioning device comprises a printing machine, conveying belts and a positioning plate, wherein the two conveyingbelts are arranged inside the printing machine, the two conveying belts are symmetrically distributed about the center of the printing machine in a left-right symmetry mode, an installing notch is formed in a printing press, the installing notch is of a rectangular column body structure, the positioning plate is inserted into the mounting notch, a central through hole is formed in the positioningplate, the central through hole is of a circular cylinder structure, a butt joint hole is formed in the inner wall of the central through hole, butting rods are inserted into the butt joint hole, oneends of the butting rods are connected with buckling plates in a sliding mode, the buckling plates are matched with a splicing groove formed in the surface of the positioning plate; and the positioning plate is arranged on the printing machine, and a guide rod arranged on the surface of the positioning plate is matched with extending rods for enclosing a workpiece, so that the deviation of the workpiece in the printing process is prevented, and the guide rod and the extension rods are easy and fast to adjust and suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a positioning device for a large-size printing mechanism. Background technique [0002] A printing press is a mechanical device that presses the inked surface on the media surface (such as paper and cloth) to form an image. It was first invented by the German Gutenberg in 1440. Modern printing machines generally consist of plate loading, ink application, and printing. Composed of 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 printing plate manually or by the printing machine Where there are text and images, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood, glass and ceramics), so as to reproduce the same prints as...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional printing machine lacks a positioning structure, which causes the workpiece to shift during the printing process, resulting in printing deviation, thereby reducing the processing quality of the workpiece and affecting the benefits of the enterprise;

[0004] 2. When the traditional printing machine prints the large-size plate structure, it needs to be manually moved, which is time-consuming and laborious, and the production efficiency is low;

[0005] 3. The working table of the traditional printing machine is fixedly installed and cannot be disassembled, resulting in damage to the table and cannot be replaced, affecting the use
