Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of plastic product raw material screening, in particular to a raw material screening device for plastic product processing. Background Art
[0002] Plastic particles are the common name for plastic particles. They are the 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 form compounds with large molecular weight, namely polymers.
[0003] Plastic particles are the raw materials for the production of general plastic products. During the production process, plastic particles often need to be screened. During the screening process, some plastic particles are sticky and easily stick to each other or aggregate together to form clumps. These clumps are difficult to pass through the screen, thereby reducing the screening efficiency. At the same time, when feeding, most of the plastic particles are directly poured into the interior of the screening device, and the plastic particles will directly accumulate on the surface of the screen, thereby affecting the effect of subsequent screening.
