[0002] Powder metallurgy is a process technology for producing metal powders or using metal powders as raw materials, and manufacturing metal materials, composite materials and various types of products through forming and sintering. Due to the advantages of powder metallurgy technology, it has become the key to solving new material problems and plays a crucial role in the development of new materials.

However, the operation of traditional screening machines relies on manual feeding from the storage container into the screening machine, with heavy labor load and limited production efficiency. In addition, the powder is diffused during operation, posing a potential threat to the occupational health of operators. In view of this, there is an urgent need for an automatic feeding device for a screening machine, aiming to innovate the traditional process, reduce labor intensity, improve production efficiency, optimize the working environment and ensure occupational health and safety.
