[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 resin and additives such as fillers, plasticizers, stabilizers, lubricants, colorants, etc. It is one of the common product materials in life. During the production process, it is generally made by melt-extruding the raw materials through an extruder.

[0003] The existing melting device for preparing plastic shells has the following disadvantages when in use: the plastic structure shell is usually melted and extruded by a fixed structure extruder, and the plastic shell structure has different requirements for quality and raw materials according to different product preparation requirements. Since the feeding component of the extruder is fixed at the end of the extruder, when producing plastic shell products with lower quality requirements or plastic shell products with single-component raw materials, all sections of the extruder still need to work, resulting in unnecessary energy waste. For this reason, we propose a plastic shell processing melting device. Utility Model Content
