Forced feeding device with mixing function

Abstract

The invention relates to a forced feeding device with a mixing function. The device is provided with a material mixing bin, and a feeding screw is provided with a positive thread section and a reverse thread section; when a driving device drives the screw to rotate, both the positive thread section and the reverse thread section push a material to be fed to the middle, one part of material is discharged from a discharge hole, and the other part of material is upwards arched and gradually raised; and when the arched material reaches a certain height, the material is dispersed to two ends, and mixing of the material is finished. Mixing and conveying of the material are realized on the same device; the device is quite compact in structure, occupies a small space, and saves land resources; and without a middle conveying step, the material is not layered, so that the quality of a processed product is improved.

Description

technical field [0001] The invention relates to a feeding device, in particular to a forced feeding device with a mixing function. Background technique [0002] In the field of plastic processing, the raw materials used generally include powder, granular or sheet materials. Due to the different requirements of the products produced, it is necessary to add additives to the materials, such as color masterbatches of different colors, antistatic agents, etc., in order to The dispersion effect of the additives in the product after processing is better, and it is more in line with people's design requirements. Generally, the materials are mixed before processing; and due to powdery, granular or flake materials, bridging and blockage are easy to occur during processing. Therefore, in the process of processing, forced conveying is generally used to solve the bridging problem.

AI Technical Summary

Problems solved by technology

[0003] In the existing plastic processing equipment at home and abroad, the materials are generally mixed in the mixer, and then forced to be transported to the processing equipment through mechanisms such as screws and springs. The bulk density and flow properties are different, which leads to the phenomenon of layering after the materials are transported to the processing equipment, which ultimately affects the quality of the processed products and other unfavorable factors; at the same time, due to the different mechanisms for mixing and forced transportation, the cost of equipment increases , the corresponding increase in equipment energy consumption and maintenance costs; in addition, due to the use of different mechanisms for mixing and forced transportation, the equipment occupies a large area, causing a huge waste of land resources in today's economic era where every inch of land is very expensive.
