Cleaning and roughening device and method for remanufacturing waste rubber conveying belt

Abstract

The invention discloses a cleaning and roughening device and method used for remanufacturing a waste rubber conveying belt. The cleaning and roughening device comprises a door-shaped rack fixedly installed on a production line, a cylinder brush roll used for cleaning and roughening the waste rubber conveying belt and a speed reduction motor driving the cylinder brush roll to rotate. A suspension board is installed on a door beam of the door-shaped rack, a brush roll support parallel to the door beam of the door-shaped rack is arranged on the portion, below the suspension board, of the door-shaped rack, and a lifting mechanism capable of enabling the brush roll support to move up and down is arranged on the suspension board. The cylinder brush roll and the speed reduction motor are respectively arranged on the brush roll support, the lower transmission portion of the cylinder brush roll is in contact with the conveying belt passing through the door-shaped rack, and the axial direction of the lower transmission portion of the cylinder brush roll is perpendicular to the motion direction of the conveying belt. According to the cleaning and roughening device and method for remanufacturing the waste rubber conveying belt, the cylinder brush roll is installed on an assembly line device, the cylinder brush roll rotates at high speed to carry out comprehensive cleaning on the surface of the conveying belt, cleaning speed is high, and efficiency is high; meanwhile, fibers on the surface layer of the conveying belt are picked up, a fluff layer is formed, and the scraping procedure and the rubber-coating procedure of the next step are facilitated.

Description

technical field [0001] The invention relates to the technical field of conveyor belt remanufacturing, in particular to a cleaning and deburring device and method for remanufacturing waste rubber conveyor belts. Background technique [0002] In the field of industrial production, conveyor belts are widely used, and ordinary waste rubber conveyor belts are usually composed of a core tensile layer and a covering rubber layer. Layers are often kept intact, and waste conveyor belts are usually remanufactured in order to save resources. At present, the conveyor belt remanufacturing method is to use the scraping method to remove the aged and damaged rubber covering layer of the conveyor belt, and then glue the upper and lower surfaces of the belt core tensile layer with new rubber and vulcanize to form a new reusable conveyor belt. However, due to the presence of dust, adherents and embedded objects on the surface of the waste rubber conveyor belt, it will affect the removal effec...

AI Technical Summary

Problems solved by technology

However, due to the presence of dust, adherents and embedded objects on the surface of the waste rubber conveyor belt, it will affect the removal effect of the rubber covering layer in the scraping process, and may even damage the cutter; at the same time, due to the gap between the rubber covering layer and the belt core tensile layer There is a difference in adhesion between the core layers, resulting in residual glue on the core layer after the scraping process; in addition, in order to strengthen the adhesion between the core layer and the new covering layer, it is often necessary to clean and roughen the core tensile layer before performing the glue coating process
