Multistage spiral feeding mechanism for automatic powder filling line

Abstract

The invention discloses a multistage spiral feeding mechanism for an automatic powder filling line. The feeding mechanism is characterized by comprising a funnel-type storage cylinder, an end cover isarranged at the top of the storage cylinder, a feeding opening is formed in the end cover, the bottom of the storage cylinder communicates with a multistage feeding pipe, the multistage feeding pipecomprises an inner discharging pipe, and the inner discharging pipe is sleeved with an outer discharging pipe capable of sliding up and down; and a longitudinal hollow shaft is rotationally installedin a mounting hole of the end cover, a spiral shaft is rotationally installed in the hollow shaft, the top of the spiral shaft extends out of the hollow shaft, a spiral part at the lower part of the spiral shaft sequentially penetrates through the storage cylinder and the inner discharging pipe to extend out of the inner discharging pipe, a closed cone body is fixed at the extending-out end of thespiral bottom, and an annular discharging opening with an adjustable size is formed between the outer discharging pipe and the closed cone body. According to the feeding mechanism, the structural design is reasonable, the problem that the flowing property of powder is poor is solved through the spiral structure, the problem of accumulation and agglomeration of the powder is solved through a material uniformizing device, and the size of the discharging opening can be adjusted according to situations, so that the precision and the stability of feeding control during powder weighing and packaging are guaranteed.

Description

Technical field: [0001] The invention relates to a feeding mechanism for an automatic powder filling line, in particular to a multi-stage auger feeding mechanism for an automatic powder filling line. Background technique: [0002] Due to its poor fluidity and easy accumulation and agglomeration, it is very important to control its characteristics during mass production. The accuracy and stability of weighing it is very difficult to control due to its poor flow and easy caking. In order to solve the problem of its poor fluidity, the method of propelling the blades of the auger is adopted; in order to solve the problem of its accumulation and agglomeration, a homogenizing device is added in the feeding cylinder. The above problems are well solved. Invention content: [0003] The purpose of the present invention is to make up for the defects of the prior art, and provide a multi-stage auger feeding mechanism for automatic powder filling lines, which solves the problem of fe...
