Polypropylene foaming particle mixing and extruding equipment and use method

Abstract

The invention relates to the technical field of plastic processing, in particular to polypropylene foamed particle mixing and extruding equipment which comprises a bottom plate; the uniform mixing heat preservation box is arranged on the upper side of the bottom plate, an automatic melting feeding device is arranged on the lower side of the uniform mixing heat preservation box, and an automatic uniform mixing device is arranged on one side of the uniform mixing heat preservation box; one end of each connecting leg is fixed on one side outside the uniform mixing heat preservation box, and the other end of each connecting leg is fixed on the upper side of the bottom plate; the fixed cover is fixed on one side of the opening of the uniform mixing heat preservation box; and the material pushing plate can slide on the inner side of the uniform mixing heat preservation box. Through the arrangement of the uniform mixing heat preservation box, the connecting legs, the fixing cover, the material pushing plate, the electric control valve, the extrusion nozzle, the feeding pipe, the electric heating ring, the supporting plate, the feeding shaft, the feeding motor, the L-shaped frame and the spiral blade, the device has the functions of automatic material melting, automatic material extrusion, rapid mixing, uniform mixing, accurate extrusion and quantitative extrusion.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a polypropylene foam particle mixing and extruding equipment and a use method. Background technique [0002] Plastic processing is also called plastic molding processing. It is a general term for various processes that convert synthetic resin or plastic into plastic products, and is a large production department in the plastics industry. Plastic processing generally includes plastic ingredients, molding, machining, joining, modification and assembly. [0003] EPP is the abbreviation of expanded polypropylene, which is the abbreviation of a new type of foam. EPP is a polypropylene plastic foam material. It is a highly crystalline polymer / gas composite material with excellent performance. With its unique and superior performance, it has become the fastest growing environmentally friendly new pressure-resistant buffer heat insulation material. EPP is also an environmen...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that the extruder in the prior art has no uniform mixing function. When the raw material is melted, the molten raw material and the plastic auxiliary agent cannot be fully and uniformly mixed, and the uneven distribution of the plastic auxiliary agent is prone to occur. And there is no precise quantitative extrusion function, and it is impossible to accurately control the extrusion volume, which may cause over-extrusion or under-extrusion, which will affect the quality of plastic parts.
