Upper suspension type automatic reverse plastic master batch cylindrical banbury mixer

Abstract

The invention relates to a master batch banburying device, in particular to an upper suspension type automatic reverse plastic master batch cylindrical banbury mixer which comprises a base, a banburying boiler and a stand column, wherein the stand column and the banburying boiler are fixedly arranged on the base; the stand column is positioned on one side of the banburying boiler; an upper suspension type stirring shaft is arranged in the middle of the banburying boiler; the bottom of the upper suspension type stirring shaft penetrates through the boiler lid and stretches into the banburying boiler; an upper stirring device and a lower stirring device are arranged at the bottom of the upper suspension type stirring shaft and form a paddle type stirring mechanism; the top end of the upper suspension type stirring shaft is connected with the output shaft of a rotary motor I; the upper end of the upper suspension type stirring shaft is connected with an automatic hoisting mechanism; the automatic hoisting mechanism is fixed on the stand column; the outer side wall of the banburying boiler is connected with an automatic reverse mechanism. The upper suspension type automatic reverse plastic master batch cylindrical banbury mixer prevents leakage of master batch, stirs more uniformly, greatly shortens the banburying time of master batch, and reduces the labor strength of workers.

Description

technical field [0001] The invention relates to a masterbatch internal mixing device, in particular to a top-suspension type automatic overturning plastic masterbatch cylinder type internal mixer. Background technique [0002] Functional plastic masterbatch is processed by resin and various mixing additives through multiple processes such as banburying. The melting points of the resin and the additives are often quite different, and the additives with low melting points melt very early in liquid form. Exists in a cauldron. Existing plastic masterbatch internal mixers are all bottom-stirring internal mixers, that is, the top of the pot body containing the mixed masterbatch in the internal mixer is provided with an opening, and the bottom of the pot body is provided with an agitator. The internal mixer with this structure has the following defects: firstly, after long-term use of the bottom agitator, its installation place is prone to wear and leakage, and leakage of the firs...

AI Technical Summary

Problems solved by technology

The internal mixer with this structure has the following defects: firstly, after long-term use of the bottom agitator, its installation place is prone to wear and leakage, and leakage of the first melted liquid additive will lead to incomplete formula in the internal mixer, seriously affecting The performance of the final product, secondly, when unloading, due to the high viscosity of the molten material after banburying, its top opening has a certain height, thus greatly increasing the work intensity of workers discharging
