Description

Technical Field

[0001] The utility model relates to the field of injection molding processing equipment, in particular to a mixing device with an automatic feeding mechanism. Background Art

[0002] Plastic particles are the raw materials used for injection molding of air conditioning panels. The raw material plastic is heated to the melting temperature by a heater. The molten plastic becomes soft and is extruded through an extrusion mechanism to form long strips of material. The long strips of material are cut into plastic particles of the required length by a cutter. The molded plastic particles are used to manufacture air conditioning panels. The plastic particles are heated and melted and then injected into the mold to form various air conditioning panels through the injection molding process. The molded plastic particles need to be pre-treated through a stirring and mixing step to ensure that the particles uniformly meet the set parameter indicators. If they are not mixed and used directly for processing and production, the internal material properties of the plastic products will be inconsistent. At the same time, the inconsistency of the plastic particles will cause the processing performance of the products to decrease. Therefore, in order to solve the above problems, a mixing device with an automatic feeding mechanism is required. Utility Model Content
