Automatic roller bending device of printing plate roller and bending method of automatic roller bending device

Abstract

The invention provides an automatic roller bending device for a printing plate roller and a bending method thereof.The bending device comprises two symmetrically-arranged bases, a curved surface rolling mechanism used for rolling a steel plate by a certain curvature is arranged on the bases, a tangent plane rolling mechanism used for rolling the tangent plane of the roller is arranged on the bases, and supporting rollers are arranged on the inner sides of the bases; a guide mechanism for further bending the steel plate is arranged in the base; the roller automatic bending machine solves the problems that an existing roller automatic bending machine of a printing plate roller is simple in structure, the bending curvature cannot be adjusted, and an uneven structure is likely to be generated on the surface of the roller in the rolling process, is reasonable in structure, can adjust the rolling curvature according to the roller curvature machining requirement, conducts flatness rolling on the surface of the roller in time, and improves the machining efficiency. The condition that the surface of the roller is uneven in the later period is prevented, and the product yield is high.

Description

technical field [0001] The invention relates to an automatic roller bending device and a bending method for a printing plate roller, and relates to the technical field of printing plate roller production and processing. Background technique [0002] Printing plate roller, also called printing steel roller. It is divided into hollow roll and solid roll, shaft roll and non-shaft roll, which are generally used for plate making. The surface of the drum is chrome-plated, and the pattern is engraved by an intaglio electronic engraving machine, and then plated with a layer of chrome. After it is done, it is delivered to the printing factory, which is often used for the printing of plastic packaging. Traditional printing plate rolls include gravure printing and letterpress printing, which have the characteristics of multi-color continuous printing. The printing plate roller is usually made of seamless steel pipe after surface treatment, which has the advantage of good printing eff...

AI Technical Summary

Problems solved by technology

[0004] Considering the cost of printing plate rollers nowadays, the rollers are often made into hollow structures, and steel rollers are set on the surface as needed, so as to avoid the problem of high cost of using solid steel rollers in the past, but in the process of roller processing In the bending process, the following problems are often encountered: 1. The bending machine in the past was relatively simple and could not be adjusted freely according to the curvature of the bending; 2. In the process of bending the roller in the past bending machine, the pressure roller and the The poor contact between the rollers leads to the uneven structure of the roller surface, and the flatness of the roller surface cannot be rolled, so the scrap rate is high; therefore, there is an urgent need for an automatic roller bending device for printing plate rollers and Its bending method to solve the above-mentioned problems
