AI Technical Summary

Problems solved by technology

Due to the large friction between the solid powder particles, the solid powder has poor fluidity and uneven flow, resulting in insufficient filling (especially in complex mold cavities), resulting in poor weight and size consistency of the product, which seriously affects product quality.
If the feeding time is short during high-speed pressing, the current feeding device cannot feed in time, which will seriously affect the pressing speed

Abstract

A shoe-shaped fluidized material feeder for the die press of dried powder is composed of a feeding unit consisting of material inlet, storage chamber, main body, several perforated tubes, air inlet, material outlet and hanging lugs, and an air source treating and controlling unit consisting of pressure releasing unit, drier and throttle valve.

Description

technical field [0001] The fluidized material shoe of the invention relates to a feeding device for a dry powder press. Background technique [0002] At present, the feeding device of the dry powder press usually uses negative pressure to suck the powder into the cavity of the die, and then presses the product. Due to the large friction between the solid powder particles, the solid powder has poor fluidity and uneven flow, resulting in insufficient filling (especially in complex mold cavities), resulting in poor consistency of product weight and size, which seriously affects product quality. If the feeding time is short during high-speed pressing, the current feeding device cannot feed in time, which will seriously affect the pressing speed. Contents of the invention [0003] The purpose of the present invention is to provide a fluidized material shoe for the disadvantages of the above-mentioned feeding device, which uses dry, low-pressure, low-flow gas to make the powder...
