Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle processing, in particular to a feeding structure for melting plastic particles. Background Art

[0002] Plastic pellets are the raw materials used to store, transport, and process plastics in semi-finished form. Plastics are a type of polymer material. Ethylene, propylene, vinyl chloride, styrene, and other materials can be produced from petroleum. Under certain conditions, the molecules of these substances can react with each other to form high-molecular-weight compounds, known as polymers.

[0003] The processing of plastic particles includes the steps of screening, weighing, proportioning, melting and injection molding. During the melting processing stage, the raw materials are fed into the melting machine through a conveyor or screw, and are melted by heating and screw rotation. The raw materials are evenly melted into a flowing liquid under high temperature and high pressure environment, preparing for subsequent molding.

Excessively fast feed rates can lead to incomplete melting, while excessively slow feed rates increase energy consumption and production costs. Existing technologies, in order to control feed rate, sometimes employ multiple sensors, coupled with speed reducers or other complex components for coordinated adjustment. This is not only inconvenient to operate but also increases production costs, leaving room for improvement. Utility Model Content
