A lightweight and durable print roll

Abstract

The invention relates to a light durable printing roll. The light durable printing roll comprises a mandrel, a cylindrical roll body and an auxiliary limiting piece. The mandrel is composed of a left end shaft, a right end shaft and a middle main shaft, and the upper portion of the mandrel is provided with a limiting clamping shoulder A. The cylindrical roll body is made of high-intensity non-metal materials, and the outer surface of the cylindrical roll body is painted with a high-temperature alloy abrasion resistant layer. The mandrel and the roll body can be assembled into a whole through the auxiliary limiting piece. The auxiliary limiting piece includes a limiting clamping shoulder B and a nut. The mandrel and the roll body are split into two independent components which can be conveniently assembled into a whole the same as an existing metal printing roll in shape and size. The mandrel and the auxiliary limiting piece are respectively made of corrosion resistant metal materials, the roll body is made of carbon fiber materials with high tensile strength and acid and alkali solution corrosion resistance, and the printing roll is light in overall weight, low in working noise, high in corrosion resistance and abrasion resistance, reliable in working, long in service life and low in daily use cost; the printing roll and the existing metal printing roll have interchangeability, so that the printing roll has high practicability and wide market application prospects.

Description

technical field [0001] The invention relates to the technical field of printing machinery manufacturing, in particular to a lightweight and durable printing roller. Background technique [0002] The printing roller is an important working part in the printing machine, generally made of wear-resistant metal materials such as steel. When working, the printing roller cooperates with the control rubber roller to perform the task of continuously and smoothly transferring ink and fountain solution printing media. Therefore, in addition to the rigidity requirements to ensure normal operation, the technical requirements of the printing roller also involve a It is the surface roughness index for normal transmission of printing media and ensuring printing quality. During the printing process, since the printing roller and the control rubber roller are always in a relatively high-speed rotating contact friction state, the surface is easily worn and easily affects the surface roughness...
