Carrier roller pneumatic rubber scraping device of belt conveyor

Abstract

The invention relates to a carrier roller pneumatic rubber scraping device of a belt conveyor. The carrier roller pneumatic rubber scraping device comprises a carrier roller, a mounted bearing, a scraper, a scraper seat, a rodless cylinder, a cylinder support, a proximity switch, a balancing weight, a glue blocking plate and the like, wherein the carrier roller is fixed to a machine frame of the conveyor through the mounted bearing, the rodless cylinder is fixed to the machine frame of the conveyor through the cylinder support and the rubber blocking plate, the axis of the carrier roller is parallel to the axis of the rodless air cylinder, the middle of the scraper seat is fixed to a sliding block of the rodless cylinder, the scraper and the balancing weight are installed at the two ends of the scraper seat, the scraper makes contact with the outer circle of the carrier roller, the contact pressure can be adjusted by increasing or decreasing the balancing weight, when the belt conveyor runs, the scraper can continuously remove rubber covering the carrier roller along with axial reciprocating motion of a sliding block on the rodless cylinder, the rubber blocking plate with the inverted-V-shaped cross section is installed above the rodless cylinder, and normal work of the rodless cylinder can be guaranteed, so that heavy physical labor of workers is relieved, the operation cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of rubber production, in particular to a pneumatic scraping device for an idler roller of a belt conveyor. Background technique [0002] In the field of rubber product production, rubber mixing is an essential first process. The various raw materials weighed according to the formula are mixed in the internal mixer and then further refined through multiple subsequent mills, and the equipment for transporting the rubber between the multiple mills is a belt conveyor. During the transportation of the rubber material, due to the certain viscosity of the rubber material, a small amount of rubber particles often stick to the conveyor belt and return. According to the structure of the belt conveyor, supporting rollers must be arranged on the lower side of the returning conveyor belt to prevent the conveyor belt from sagging. roll on. For belt conveyors that work continuously, there will be more and more glue on the idler r...

AI Technical Summary

Problems solved by technology

Due to the uncertain position and uneven thickness of the rubber covering the roller, the outer circle of the roller is uneven, which leads to the frequent deviation of the conveyor belt and even rapid damage, which seriously affects the continuous and stable operation of the rubber mixing production line. Reduced production efficiency, increased equipment maintenance times and operating costs

[0003] At present, the problem of roller glue encountered in rubber production is manually cleaned. The cleaning process requires equipment shutdown. Not only is the labor intensity of the workers high, but also the cleaning efficiency is low and it is difficult to clean up.

Although some rubber companies have adopted anti-adhesive coating treatment on the surface of the idlers and conveyor belts with special anti-adhesive materials, the cost is too high, and the anti-adhesive effect of the idlers is not obvious

A pneumatic scraping device for rollers of belt conveyors is proposed, which can realize continuous and stable automatic scraping of rollers, with a high degree of automation, and solves the problems of conveyor belt deviation and rapid damage caused by rollers covered with glue. Increased production efficiency and reduced operating costs
