[0032] Working principle: during operation, air is compressed into the feeding barrel 3 through the vacuum compressor 4, and the compressed air passes through the air filter plate 5 to filter out dust and impurities in the compressed air. When the compressed air is supplied to the feeding barrel 3, negative pressure is generated in the feeding barrel 3 to form a vacuum airflow, and the raw materials are sucked into the feeding hose 7 connected to the feeding barrel 3 to form a material airflow.

As mentioned above, during feeding, the raw materials are driven by the spiral blade 114, and then the feeding hose 7 is assisted to move the raw materials from the feeding tank 1 into the feeding barrel 3, so that the raw materials are fed faster and the feeding efficiency is improved. During feeding, the transmission shaft 13 is driven to rotate by the driving motor 12, and the transmission shaft 13 drives the stirring rod 15 fixedly connected to the fixed shaft 14 to rotate, so that the stirring rod 15 stirs the powder raw materials, thereby reducing the situation where the powder raw materials are clumped or adhered in the feeding tank 1, thereby blocking the feeding hose 7 or the raw materials are adhered during discharge, affecting the quality of the powder raw materials during feeding. During cleaning, the scraper 16 connected to the stirring rod 15,By scraping the inner wall of the feeding tank 1, the residual raw materials on the inner wall of the feeding tank 1 are reduced. By setting the scale 22 and the anti-skid pad 21, the raw materials in the feeding tank 1 can be observed at any time through the scale 22.
