Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a stirring device for melting plastic particles. Background Art

[0002] Plastic is a high-molecular compound made from monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between that of fiber and rubber. It is composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. Plastic products are widely used, and the huge downstream industries provide strong support for the development of my country's plastic products industry. When processing plastic products, the plastic granular raw materials need to be melted and stirred while melting.
