AI Technical Summary
During the feeding process of preparing metal powder briquettes with a high specific gravity, the powder is prone to accumulate on the inclined plate of the hopper, forming a blockage. This leads to discontinuous feeding, affects production continuity, and may cause safety accidents. Existing solutions rely on manual intervention and are inefficient.
Design a feeding and stacking scraper device, including a coupling, a main shaft, a screw, and a scraper. The scraper is close to and inclined to the feed bin inclined plate. The scraper scrapes off the accumulated material as it rotates with the main shaft, ensuring that the material automatically falls to the bottom feed screw and realizing continuous feeding.
It enables continuous feeding of powder materials, improves production efficiency, reduces manual intervention, avoids safety hazards, and saves labor resources.
