A paper delivery device for a printing press

Abstract

The invention discloses a paper collecting device of a printing machine. The paper collecting device comprises a machine frame, a base, supporting beams, first sliding rails, positioning plates, connecting rods, a supporting plate, second sliding rails, a driving motor, driving wheels, a transmission belt, a handle, a transmission shaft, a lifting wheel, a lifting chain, an air pump, a valve, an air pipe, high-pressure air nozzles, compression roller shafts, compression rollers, third sliding rails, compression roller arms, sliding blocks, retainer rings, protrusions, notches and balls. The paper collecting device has the advantages of being reasonable and simple in structure and convenient to use; the surface temperature of the paper can be effectively reduced when the paper subjected to printing is collected, and therefore a paper tape subjected to printing drying can be rapidly cooled, the side of the paper is prevented from curling, later-stage cutting is facilitated, and the quality of the product is guaranteed; meanwhile, the length of the compression rollers can be adjusted according to actual processing conditions to meet the paper width requirements, and therefore the phenomenon that the paper is deviated in the conveying process due to the fact that the compression rollers are too long is avoided, the normal production line production is achieved, the production efficiency is improved, and the use is flexible and convenient.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to a paper delivery device of a printing machine. Background technique [0002] A machine for printing text and images. Modern printing machines are 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. The invention and development of the printing press play an important role in the spread of human civilization and culture. The existing paper delivery d...

Problems solved by technology

The invention and development of the printing press play an important role in the spread of human civilization and culture. The existing paper delivery device has a fixed structure when delivering paper, and it is difficult to adjust the length of the pressure roller according to the size of the paper. It is very inflexible to use, and The temperature of the paper after processing is high. If the temperature is not cooled in time, the sides of the paper will be curled, which will affect the quality of the paper.
