TECHNICAL FIELD

[0001] The application belongs to the technical field of feeding device, and particularly relates to a high-precision inner-rotation type plastic particle and powder feeding device. BACKGROUND

[0002] In the production process of plastic products, accurate and uniform feeding of plastic particles and powders is a key link to ensure product quality and production efficiency. Traditional feeding devices mostly adopt external screw conveying or gravity feeding, and the material is easily affected by the change of the material accumulation height (i.e. the material gravity) in the hopper during conveying, resulting in unstable feeding speed, uneven feeding, pulsation or blockage and other problems, which seriously affect the accuracy and continuity of feeding.

[0003] In addition, in conventional feeding equipment, the material has a large contact area with the inner wall of the equipment during conveying, and the frictional resistance is high. Especially for powdery materials with poor fluidity, wall sticking and bridging phenomena are easily generated, further reducing the stability and accuracy of feeding. At the same time, the surface roughness of the material and the interaction between particles also adversely affect the flow performance, increasing the load of the driving system, leading to increased energy consumption, accelerated wear of mechanical parts, frequent equipment maintenance and shortened service life. Therefore, the existing feeding device has obvious deficiencies in dealing with high-precision, continuous and low-energy production requirements, and there is an urgent need for a new feeding device that can effectively isolate the pressure interference of the hopper, reduce frictional resistance and improve feeding uniformity and accuracy to meet the requirements of modern plastic processing industry for automation and high-quality production.
