Description

Technical Field

[0001] The utility model relates to the technical field of abrasion machines, in particular to a roller-type feeding belt abrasion machine. Background Art

[0002] Conveyor belts are widely used in agriculture, industrial mining, and transportation to transport a variety of solid, bulk, and powdered materials or finished goods. They offer continuous, efficient, and high-angle transport. They are also safe, easy to use, and maintain, offering low freight costs. They can also shorten transportation distances, reduce project costs, and save manpower and material resources. Wear resistance is a key performance indicator for conveyor belts, so it's often tested using an abrasion tester.

[0003] The standard stipulates that the wear generated by rubbing a cylindrical specimen against a certain grade of emery cloth over a specified distance at a specified contact pressure and area is measured. The wear occurs at one end of the cylindrical specimen. The emery cloth is attached to the surface of a rotating drum, and the specimen is pressed against the cloth, moving laterally along the drum. During this process, the friction between the specimen and the emery cloth produces a large amount of debris. This debris adheres to the drum, affecting the coefficient of friction of the cloth and the accuracy of the test results. This requires constant cleaning, which wastes considerable manpower and time. To address this problem, we have designed a drum-type feeder belt abrasion tester. Summary of the Invention

The two cleaning brushes 8 are both against the rotating drum 2 and are respectively located on the left and right sides of the mounting block 5. The U-shaped plate 7 moves with the mounting block 5, so that the two cleaning brushes 8 can clean the rotating drum 2 on both the front and rear sides of the sample to prevent the residual debris on the rotating drum 2 from affecting the wear work.

[0025] The wear machine body 1 is provided with a dust collection assembly, which includes a dust box 15 installed in the wear machine body 1, a dust box 17 that is slidably connected to the dust box 15 and abuts against the inner side wall of the dust box 15, a filter frame 18 is fixedly connected to the dust box 17, and a filter screen is installed on the filter frame 18. The filter screen can filter out the wear debris for centralized processing. The front and rear side walls of the filter frame 18 are fixedly connected with a baffle located between the dust box 17 and the cover plate 6 and abutting against the inner side wall of the dust box 15, so as to prevent the debris from passing through the filter frame 18 and the collection The gap between the inner walls of the dust box 15 is floating, and the upper end of the filter frame 18 is fixedly connected to the cover plate 6 that abuts the upper end of the dust box 15.
