Abstract

The invention provides a hot mixing machine for producing plastic. The hot mixing machine comprises a shell, wherein the shell is internally provided with a stirring shaft; the stirring shaft is internally provided with a cavity; a plurality of air outlets are formed in a side wall of the cavity; a plurality of stirring paddles are uniformly arranged on the stirring shaft; a friction plate is arranged under each stirring paddle; each friction plate is annular; a plurality of bulges are arranged on the lower sides of the stirring paddles and the upper surfaces of the friction plates; the bottom of the stirring shaft is communicated with an air inlet pipe through a rotary air pipe connector; the air inlet pipe is further connected with a hot air supplying system; and the hot air supplying system comprises an air blower and a heating chamber. The hot mixing machine for producing the plastic, provided by the invention, has the beneficial effects that the bulges on the stirring paddles and the bulges on the friction plates can be used for wearing materials, so that heating is accelerated and the hot mixing efficiency is effectively improved; the hot air supplying system is matched with the bulges, and thus the heating of the materials is accelerated; and a circulating pipe is arranged and is used for repeatedly utilizing passing heat.

Description

technical field [0001] The invention relates to the technical field of plastic production, in particular to a heat mixer for plastic production. 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 same time during this period.
