Automatic quantitative cold-state feeding vertical extruder

Abstract

The invention belongs to the technical field of extruders, and particularly relates to an automatic quantitative and cold-state feeding vertical extruder. The vertical extruder comprises a rack and athree-plate four-column mold frame arranged at the top of the rack, wherein the three-plate four-column mold frame is fixedly connected with the rack, and an adjusting mechanism is arranged on the rear side of the three-plate four-column mold frame; the adjusting mechanism is fixedly connected with the three-plate four-column mold frame, and an automatic quantitative cold-state feeding system usedfor feeding is arranged at the top of the adjusting mechanism. Through the arrangement of the automatic quantitative cold-state feeding vertical extruder, a designed stirring hopper and a designed automatic cooling rotary hopper overcome the defects that part of materials condense when heated and feeding is not smooth in the processing process, and the out-of-mold cooling and stirring functions are added, so that the continuous stability of powdery material processing and feeding is ensured; and a precise and stable PLC system and the intuitive and understandable human-computer interface configuration are convenient for production operation and monitoring and tracing of the production process, and the popularization and application of a new material and a new process can be effectively promoted.

Description

technical field [0001] The invention belongs to the technical field of extruders, in particular to an automatic quantitative cold-feeding vertical extruder. Background technique [0002] Plastic extruders in a broad sense can be used for the processing of various plastic moldings such as pipes, films, rods, packing belts, plates (sheets), profiles, granulation, and cable coating. Powdery plastic materials are processed through the extrusion system. It is plasticized into a uniform melt, and under continuous high-pressure extrusion, it is continuously extruded by the screw into the head or mold, and finally cooled and formed. High torque and high speed, usually composed of a large power motor, reducer and transmission components, etc., to provide high pressure and high power for the extrusion and plasticization of materials, the extruder is usually electrically heated, and the heating plate is installed on the body, Head, mold and other parts, heat the powder plastic in the ...

AI Technical Summary

Problems solved by technology

[0003] To sum up, with simple mechanical structure and processing technology, plastic extrusion molding machinery is one of the widely used models in the plastic processing industry. Some materials are easily hardened when the processing environment is heated above 30 degrees, and the fluidity changes significantly. Poor, or even agglomeration to block the feed port, the original production process, method and mechanical structure can no longer effectively meet the processing and application of new materials, for the poor fluidity, low temperature resistance, thermal instability, etc. The original production process and extrusion processing machinery should be improved in a targeted manner, and even peripheral auxiliary mechanical mechanisms should be added locally to improve the smooth continuity of material supply, product performance and appearance dimensional stability
