Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a polyurethane blade cleaning device. Background Technology

[0002] Polyurethane sweepers refer to sweepers whose blades are made of polyurethane. The physical properties of polyurethane determine the sweeper's application range. Polyurethane is a new type of high-molecular synthetic material between rubber and plastic, possessing both the hardness of plastic and the elasticity of rubber. It will not damage the conveyor belt during operation, and it also has a good cleaning effect, which can extend the service life of the conveyor belt. Polyurethane sweepers are a replacement product for alloy sweepers and are suitable for enterprises in coal mines, power plants, steel mills, petrochemical plants, etc.

[0003] When the cleaner is installed, the two ends are often not at the same level, which causes the blade to tilt. The blade is not in close contact with the conveyor belt, resulting in the conveyor belt not being cleaned properly. The tilted blade can also easily damage the conveyor belt. Utility Model Content
