Description

Automatic cleaning and recycling device for belt conveyor

Technical Field

The invention belongs to the technical field of automation equipment, and particularly relates to an automatic cleaning and recycling device for a belt conveyor.

Background

A belt conveyor is a machine that uses friction drive to transport material in a continuous manner, and it can form a material conveying path from an initial feeding point to a final discharging point on a given conveying line. The conveying device can be used for conveying both broken materials and finished articles. Besides pure material conveying, the device can also be matched with the requirements of technological processes in the production flows of various industrial enterprises to form a rhythmic line production conveying line. The belt conveyor is widely applied by virtue of the advantages of simple operation, strong conveying capacity, automatic operation and the like.

In the actual production process, the water content of some materials is higher, leads to wherein some materials when uninstalling the cylinder, the condition that can not uninstall and attach to on the conveyer belt top layer appears, along with the increase of conveyer operating time, can add up more material residues on the transfer surface of conveyer belt, and remaining material is attached to and is rotated along with the conveyer belt on the transfer surface together, has increased the work load when transmission roller rotates, has reduced the conveying efficiency of conveyer belt. Meanwhile, the surface of the conveying belt is abraded when the belt conveyor works for a long time, and fine materials are easily entrained under the surface of the concave-convex conveying belt and gather at the lower side of the conveying belt at the bottom of the return stroke, so that the problem of 'material return' is caused. Under the influence, the carrier roller is easy to block and rotate, and the conveyer belt deviates from a normal track in normal operation, so that great uncertainty is brought to safety production.

In response to this problem, a cleaning device is often provided in the front of the drum of the belt conveyor to clean the surface of the belt. The traditional cleaning device is a spring cleaner and an alloy rubber cleaner, and the working principle of the spring cleaner is that a scraper blade is close to the surface of a conveying belt under the action of the elastic force of a spring, so that materials attached to the conveying belt are cleaned. For example, the invention of chinese patent publication No. CN203173416U discloses a spring sweeper mechanism for a belt conveyor, which includes a head frame, a head wheel is disposed on the head frame, a belt is wound around the head wheel, a guide rod is fixed on the head frame, a sliding sleeve is movably connected to the guide rod, the sliding sleeve is connected to a spring, a positioning seat is connected to one side of the sliding sleeve, a scraper is connected to the positioning seat, and the scraper contacts the belt. Compared with a spring sweeper, the alloy rubber sweeper has the working principle that the elastic force of the rubber rod is utilized to play a role. In addition, the scraper plate material is changed into hard alloy, and when the conveying belt and the materials are separated, the scraper plate material is close to the surface of the conveying belt, and the materials on the surface of the conveying belt are cleaned. For example, the alloy rubber sweeper shown in the chinese utility model with the authorized bulletin number CN206068795U comprises a frame, a sweeping board and a plurality of rubber elastic blocks arranged on the sweeping board, wherein the sweeping board is arranged on the frame. In the actual production process, when adopting traditional cleaning device to clean the conveyer belt, appear the scraper blade easily and damage the conveyer belt surface and clean the not good problem of effect.
