Extrusion forming device for production of plastic granules

Abstract

The invention relates to the technical field of production of plastic granules, and discloses an extrusion forming device for production of the plastic granules. The extrusion forming device comprisesan extrusion cylinder and a cooling cylinder, the cooling cylinder is fixed to the right side of the extrusion cylinder, and an extrusion structure and a cooling structure are arranged in the extrusion cylinder and the cooling cylinder. The extrusion structure comprises a driving motor, a rotary rod, an auger, electric heating pipes, a scraping slot, an extension rod and a scraper, wherein the rotary rod is transversely and rotationally installed in the extrusion cylinder through a first bearing, the auger fixedly surrounds the outer ring of the rotary rod through welding, the electric heating pipes are fixedly embedded into the inner wall and the outer wall of the extrusion cylinder, and the electric heating pipes is arranged around the inside of the outer wall of the extrusion cylinder.By fixedly welding three mesh plates to the lower side in the cooling cylinder, and arranging fans above the cooling cylinder to blow air into the cooling cylinder, agglomerate plastic granules can be broken up under the action of through holes of the mesh plates, the plastic granules can be cooled by the fan through blowing, and the plastic granules can be well prevented from being caked.

Description

technical field [0001] The invention relates to the technical field of plastic granule production, in particular to an extrusion forming device for plastic granule production. Background technique [0002] At present, plastic pellets are plastic granules, which refer to granular plastics, which are generally divided into more than 200 types and can be subdivided into thousands of types. In daily life, recycled granules can be used to make various plastic bags, barrels, pots, toys, Furniture, stationery and other living utensils and various plastic products, the raw materials of any plastic products are plastic granules, and the plastic granules are extruded from the raw materials in a special extrusion molding machine. [0003] When producing plastic granules, the raw materials are melted in the extrusion barrel and then extruded to form granulated plastic granules. Since the extruded plastic granules are relatively soft and contain a certain amount of heat, the plastic gran...

AI Technical Summary

Problems solved by technology

[0003] When producing plastic granules, the raw materials are melted in the extrusion barrel and then extruded to form granulated plastic granules. Since the extruded plastic granules are relatively soft and contain a certain amount of heat, the plastic granules are easy to accumulate into blocks. Although the existing Cooling treatment of extruding equipment can reduce such phenomenon, but some plastic particles have already formed structure before cooling, and the phenomenon of agglomeration cannot be compared.
