Light high-strength gravure plate roller and machining method thereof

Abstract

The invention relates to a light high-strength gravure plate roller and a machining method thereof. The gravure plate roller comprises a roller type plate face. A carbon fiber pipe, a nickel layer, a copper layer and a chromium layer are sequentially arranged on the roller type plate face from interior to exterior. A printing plate pattern is carved on the surface of the copper layer, and the chromium layer is plated on the outer surface of the copper layer on which the pattern is carved. The machining method comprises the steps that the carbon fiber pipe is obtained through the carbon fiber winding technology or the carbon fiber pipe coiling technology; the nickel layer is plated on the outer surface of the carbon fiber pipe; the copper layer is plated on the outer surface of the nickel layer; the printing plate pattern is carved on the upper face of the copper layer; and after pattern carving, the chromium layer is plated on the outer surface of the copper layer. According to the light high-strength gravure plate roller and the machining method thereof, the weight of the gravure plate roller can be reduced, the strength of the gravure plate roller is improved, and accordingly the purposes that the motor power and the electric power cost are reduced, the production efficiency is improved, and dismounting and mounting are easy are achieved.

Description

technical field [0001] The invention belongs to the technical field of gravure printing, and in particular relates to a light-weight and high-strength gravure plate roller and a processing method thereof. Background technique [0002] As one of the four major printing methods, gravure printing is widely used in printing, packaging and graphic publishing due to its advantages of thick ink layer, bright color, high saturation, high printing plate durability, stable printing quality and fast printing speed. occupies an extremely important position in the field. In the gravure printing equipment, the most critical part is the gravure plate roller. The pattern to be printed is engraved on the copper plating of the gravure plate roller. When printing, the ink in the ink fountain is filled into the pits of the gravure plate roller. , The ink on the surface of the plate roller is scraped off with a doctor blade, and the ink contained in the pit is directly imprinted on the substrat...

AI Technical Summary

Problems solved by technology

The currently used gravure plate rolls are usually made of 4 layers of metal materials (steel, nickel, copper, chromium from the inside to the outside), which have problems such as heavy weight, low strength, and low efficiency.

[0003] The base roll of the gravure roll is generally made of seamless steel pipe. In order to meet the requirements of mechanical precision, the wall thickness of the steel pipe is from 10mm to 30mm, and the large-size roller is thicker, so the weight is relatively heavy. At the same time, in order to drive the operation of the roller, A high-power motor is required, which increases the cost of the motor. At the same time, due to the inertia, it takes a long time to drive the guide roller to the working speed, and the production efficiency is low.
