Blanking device for exhausting and feeding

Abstract

The invention relates to a blanking device for exhausting and feeding, which is arranged on the top of a spiral drum and comprises a feeding cylinder and an exhausting feeding drum, wherein the feeding cylinder and the exhausting feeding cylinder are both arranged on the top of the spiral drum; a feeding input port is arranged on the top of the feeding cylinder while a feeding output port is arranged on the bottom; an exhaust port is arranged on the top of the exhausting feeding cylinder while an air inlet is arranged on the bottom; and the feeding output port of the feeding cylinder is communicated with the air inlet of the exhausting feeding cylinder. Compared with the prior art, the blanking device for exhausting and feeding has the advantages that the structure is simple, the practicability is higher, the gas in the mixed material can be efficiently exhausted, the phenomenon of returning materials is reduced, the machine is conveniently washed when the device is used for feeding resin, and the washing operation is simple, convenient and quick.

Description

technical field [0001] The invention relates to a feeding device, in particular to a feeding device used for exhausting and feeding. Background technique [0002] During the production process of filler products in the modified plastics industry, the resin and filler powder are mixed, and transported to the extrusion equipment through the feeding system for melt mixing, co-smelting, stripping and pelletizing, and finally become a modified product. The extrusion equipment needs to be cleaned during the color matching experiment, and resin feeding is usually used for cleaning. [0003] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of the prior art blanking device, including a blanking barrel 1 and a screw barrel 2. The lower barrel 1 is fixedly connected with the screw barrel 2 through the lower barrel fixing bolts 11, and the screw barrel 2 is coaxially provided with a screw sleeve 21 inside. The main disadvantages are as follows: the feeding pr...

AI Technical Summary

Problems solved by technology

The main disadvantages are as follows: the feeding process of filling products will cause poor feeding, non-feeding and returning. Through the feeding system, it enters the screw barrel and is taken away by the twin-screw to enter the next process. The gas under the internal pressure of the screw pushes the light powder out of the feeding port, resulting in the phenomenon of material return. Affected by the return material, the product capacity and product quality are not stable Affected by different degrees, it directly leads to cost increase and quality hazards; every time the color matching test is shut down for cleaning, the feeding system needs to be disassembled before resin can be put into the cleaning operation, which is time-consuming and inconvenient to operate
