Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a quantitative feeding device for powder and particle blending. Background Art

[0002] Blending refers to mixing together. It is a physical method that allows several materials to be evenly mixed to improve material performance. During the production and processing of plastic particles, the base material and additive powders are evenly mixed in the mixer and added to the feeding hopper. The blended base material is heated, melted, plasticized, and mixed in the screw through an automatic feeding device, and then extruded, pulled, cooled, and pelletized through a die. This process is called the physical blending modification technology of plastics, among which the preliminary material mixing technology is a particularly important process in the entire plastic processing technology process.
