A high -efficiency heat hybrid machine for the plastic processing industry

Abstract

An efficient heat blending machine used for the plastic processing industry comprises a shell, wherein a main stirring shaft is arranged in the shell, the main stirring shaft is connected with a motor located above the shell, a hollow inner cavity is formed in the main stirring shaft, the side wall of the hollow inner cavity is provided with a plurality of air outlets, the outer part of the main stirring shaft is provided with a helical blade, the outer part of the helical blade is provided with a circulating sleeve, and the side wall of the bottom of the circulating sleeve is provided with a circulating opening; the upper part of the main stirring shaft is symmetrically provided with two horizontal rods, and the other ends of the horizontal rods are fixedly provided with subsidiary stirring shafts. The efficient heat blending machine has the beneficial effects that bulges on stirring paddles and bulges on a guide plate can rub materials, a conventional stirring paddle structure is changed, and a heating effect and a heating speed are improved and increased; the helical blade is arranged to circularly treat the materials, and the problem of uneven heating of the materials can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a high-efficiency heat mixer used in the plastic processing industry. Background technique [0002] Thermomixer is one of the essential equipment in plastic processing industry. It is mainly used for uniform mixing of various resins such as polyvinyl chloride and other auxiliary materials and achieving the purpose of process temperature in a short time. It is also suitable for coloring and mixing of polyethylene, polypropylene and other pellets and drying before warm resin products. The mixing process is not only a physical process, but also a complex chemical process. The high-speed impact, shearing, throwing, and self-friction of the blades in the thermomixer make it reach the specified end point temperature according to the set temperature gradient requirements. , and complete the requirements of homogenization, macromoleculeization and pre-plasticization at the sa...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the structural design of the stirring blades is unreasonable, resulting in slow material friction heat generation, resulting in poor production efficiency; and the lack of external auxiliary heat during mixing will also lead to poor results; in addition, in the rotating shaft In the process of driving the blades to work, the shell will generate a large vibration, which will affect the processing effect of the material
