Alumite leapfrog driving traction roller of gilding press

Abstract

The invention relates to parts and components of packaging and printing equipment, in particular to an alumite leapfrog driving traction roller of a gilding press. The alumite leapfrog driving traction roller comprises a roller body and roller shafts fixedly connected with the two ends of the roller body. One end of the roller body is closed, and the other end of the roller body is open. The roller shaft connected with the open end of the roller body is provided with an axial hole, and by means of the axial hole, an inner cavity of the roller body is communicated with the outside. The roller body is made of powder metallurgy porous materials. According to the traction roller, on the premise that it is guaranteed that slipping is avoided in the aluminum traveling process and the leapfrogging process, frequent cleaning and maintenance of the traction roller can be omitted, and long-term stable operation of the traction roller is guaranteed.

Description

technical field [0001] The invention relates to parts in packaging and printing equipment, in particular to an anodized aluminum step-driven traction roller in a bronzing machine. Background technique [0002] In the packaging and printing industry, the hot stamping process is a post-press processing technology that is commonly used. Whether it is a circular pressure stamping machine, a flat pressing hot stamping machine, a web line hot stamping machine or a sheet-fed hot stamping machine, it is necessary to achieve continuous Hot stamping requires the use of anodized aluminum step-driven traction devices, which include driving stepper motors and anodized aluminum step-driven traction rollers. [0003] The utility model patent with the patent number of 2015203185423 discloses an anodized aluminum step-driven traction roller. The anodized aluminum skip-driven traction roller includes a cylindrical roller body and a roller shaft fixedly connected to both ends of the roller bod...

AI Technical Summary

Problems solved by technology

[0004] The anodized aluminum jump-driven traction roller with this structure is covered with mechanically processed adsorption holes on the cylindrical surface of the roller body. During operation, these adsorption holes are easily blocked by dust, and the adsorption holes need to be cleaned frequently. The process is labor-intensive and time-consuming and affects production

In addition, the rubber layer on the outer cylindrical surface of the roller skeleton will scrap the entire traction roller due to wear after a period of use. Generally, it needs to be replaced with a new traction roller after about 3 years of use, so the maintenance cost is very high
