AI Technical Summary
When conveying adhesive powders, existing screw feeders often cause the material to adhere to the inner wall of the hopper, leading to cleaning difficulties, material waste, and production interruptions, thus affecting production efficiency and costs.
The device employs a scraping mechanism and a vibrating motor. The scraping mechanism drives the scraper unit to rotate and scrape the inner wall of the hopper via the drive motor, while the vibrating motor reduces material adhesion. The design and material selection of the scraper unit ensure scraping effect and device stability.
It effectively reduces material residue on the inner wall of the silo, lowers cleaning costs and time, improves production continuity, reduces the risk of blockage, and enhances production efficiency and equipment applicability.
