Description

Technical Field

[0001] The utility model relates to the technical field of mixing and stirring machines, in particular to a granular plastic mixing and stirring machine. Background Art

[0002] Plastic particles are the common name for plastic particles. They are the raw materials for plastic storage, transportation and processing in the form of semi-finished products. Plastic is a type of polymer material. Ethylene, propylene, vinyl chloride, styrene, etc. can be produced from petroleum. The molecules of these substances can react with each other under certain conditions to generate compounds with large molecular weights, namely polymers. When producing colored plastic products, different colored plastic particles need to be mixed for color matching. At this time, a granular plastic mixer is needed. However, the existing granular plastic mixer still has some shortcomings, such as the inability to dissipate heat from plastic particles during mixing. For example, during mixing, plastic particles will adhere to the inner wall and the material will sink to the bottom, making it inconvenient to discharge. Utility Model Content
