Description

Technical Field

[0001] This utility model belongs to the field of extruder technology, and in particular relates to a heating structure for extrusion processing of plastic granules. Background Technology

[0002] Plastic granules refer to granular plastics, which can be broadly classified into more than 200 types and subdivided into thousands of types. Common plastic granules include general-purpose plastics, engineering plastics, and specialty plastics. In daily life, plastic granules can be used to manufacture various plastic bags, buckets, basins, toys, furniture, stationery, and other household items and plastic products. In the process of processing plastic granules into plastic products, extrusion molding machines are indispensable. Extrusion molding machines are commonly used equipment in the plastic granule processing process. The main body of a plastic extruder is the extruder itself. The plastic is plasticized into a uniform melt through the extrusion system inside the extruder. Under the pressure built up in this process, it is continuously extruded by the screw through the die head and shaped into plastic granules through the extrusion mold inside the die head. After the plastic granules cool, they form various plastic products.

[0003] However, existing technologies have some problems: current plastic pellet heating extrusion involves heating the box with heating tubes to melt the plastic. However, when the melted plastic is introduced into the extruder, some of it comes into contact with cold air, causing some of the plastic to harden and affecting the heating effect. Therefore, we propose a heating structure for plastic pellet processing extrusion. Utility Model Content
