A winding device for a printing machine

Abstract

The invention discloses a rewinding device for a printing machine, comprising a rewinding roller, limit plates are movably installed at both ends of the rewind roller, and a rewinding pretreatment device with the function of drying paper is fixed on the outside of the two limit plates , the outer side of the winding roller is provided with a size adjustment assembly with a deviation correcting function, and the product of the present invention uses a winding pretreatment device with a paper drying function to dry the surface of the rolled paper to avoid that the ink printed on the surface of the paper is not dry , Squeezing contact with the back of the inner paper will affect the printing effect, thereby improving the printing effect of the paper. At the same time, through the size adjustment component, it can meet the winding of paper of different sizes, and avoid wrinkles at both ends of the paper, which will affect the quality of the finished paper.

Description

technical field [0001] The invention relates to the technical field of printing and rewinding, in particular to a rewinding device for a printing machine. Background technique [0002] A printing press is a machine that prints text and images. Modern printing machines are generally composed of plate loading, ink application, embossing, paper feeding 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, then apply the ink to the place with the text and image 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 played an important role in the spread of human civilization and culture. [0003] Existing printing machines...

AI Technical Summary

Problems solved by technology

[0003] Existing printing machines are all rewound by rewinding rollers, but when rewinding, the paper is rewound before it is completely dry, so that the printed text and images are embossed on the back of the inner paper, which affects the quality of the printing effect, and in When rewinding paper with a small size, because the length of the rewinding roller is greater than the width of the paper, there is a phenomenon of uneven winding at both ends of the paper, which makes the two ends of the paper prone to wrinkles and affects the quality of the finished paper. For this reason, we propose a Winding device for printing machine
