Technical Field

The invention particularly relates to a hot mixer for plastic processing.

Background

The hot mixer is one of the indispensable equipments in plastic processing industry, is mainly used for uniformly mixing various resins such as polyvinyl chloride and the like with other auxiliary materials, achieves the purpose of process temperature in a short time, and is suitable for coloring and mixing granules such as polyethylene, polypropylene and the like and drying before warm resin products. The mixing process is not only a physical process but also a complex chemical process, and the high-speed impact, shearing, throwing, material self-friction and other effects of the blades in the hot mixer enable the blades to reach a specified end point temperature according to a set temperature gradient requirement, and meanwhile, the requirements of homogenization, large molecule, preplastication and the like are met.

The existing common hot mixer generally uses a fixedly placed mixing drum, and has the problems that a mixing knife cannot break up plastic lumps agglomerated at the inner dead corner of the mixing drum and the discharging is difficult.

Disclosure of Invention

The invention aims to solve the defects of the prior art, and provides a hot mixer for plastic processing, which comprises a rack and a mixing assembly, wherein the rack comprises a left supporting assembly and a right supporting assembly, the left supporting assembly comprises a left supporting column with a bent upper section and a bent lower section, a speed reducing motor is arranged on the upper section of the left supporting column, and a rotating shaft of the speed reducing motor is connected with the axis of a driving gear; the top end of the left support column is provided with a left bearing support; the right support component comprises a right support column, and a right bearing support is arranged at the top end of the right support column; the mixing assembly comprises a mixing barrel, a left rotating shaft and a right rotating shaft, wherein the left rotating shaft and the right rotating shaft are arranged on two side walls of the mixing barrel; the right end of the right rotating shaft is clamped in the right bearing support; the mixing drum is provided with a sealing cover at the upper end and a high-speed motor at the lower end, a main shaft of the high-speed motor is connected with a mixing shaft arranged in the mixing drum, and the mixing shaft is provided with a plurality of pairs of mixing knives.

In order to better realize the sufficient mixing of the plastic, the upper and lower sections of the left supporting seat are preferably bent at an angle of 120-150 degrees.

Preferably, deep groove ball bearings are mounted in the left bearing support and the right bearing support.

Preferably, the diameter of the driven gear is 2 times of that of the driving gear.

Preferably, a collector ring is arranged in the middle section of the right-turning rotating shaft and is connected with the right supporting column through the collector ring.

Preferably, the sealing cover is sleeved with a high-temperature-resistant sealing ring.

Preferably, the mixing knives are arranged along the axial direction at intervals in sequence.

Preferably, the mixing blade is in the shape of a paddle.

Has the advantages that: in use, when the mixing drum is used for internal mixing, the mixing drum is made to revolve by a left rotating shaft and a right rotating shaft, and the drum body is also in an inclined state due to the bending structure of the left supporting column, and plastic materials agglomerated and bonded in the mixing drum are continuously moved based on the inclination of the drum body and the revolution of the left supporting column, so that the plastic materials are cut by the mixing knife and are uniformly mixed. After mixing, can directly invert the stack shell through revolution, open sealed lid and unload convenient and fast.
