Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle processing, in particular to a particle conveying device for plastic particle production. Background Art

[0002] Plastic granules, also known as plastic particles, are raw materials for storage, transportation and processing of plastics in the form of semi-finished products; plastics are a type of polymer material. Ethylene, propylene, vinyl chloride, styrene, etc. can be produced using petroleum as raw material. The molecules of these substances can react with each other under certain conditions to generate compounds with large molecular weight, namely polymers. In the production process of plastic granules, an extruder is used to extrude the plastic into strip-shaped plastic products, which are then cut into granules.

[0003] The processing of plastic products requires the transportation of various plastic granule raw materials to extruders and other equipment. The existing plastic granule conveying equipment is a simple conveyor belt or screw conveyor. The dust and impurities mixed in the plastic granules cannot be removed well during the conveying process. Since plastic granules are inevitably exposed to the environment during production and transportation, especially some small-scale, workshop-produced plastic granules are mixed with more dust and impurities. If the dust and impurities in them cannot be removed well, it will affect the quality of the extruded cast body. Utility Model Content
