Abstract

A spiral material-supplying apparatus features that the granular material can be uniformly discharged and when the rotation of spiral drive axle is stopped, the granular material can not be dropped out of its discharge port. A rotary spiral drive axle with spiral material-delivering blade is contained in a material supplying barrel. Multiple material isolating blades are radially on said spiral drive axle.

Description

technical field [0001] The present invention relates to a spiral material supply device for powdery or granular materials such as a screw feeder, and more specifically, to a device for feeding powdery or granular materials stored in a hopper to a next step such as a molding machine. Spiral material supply device for process supply. Background technique [0002] In the past, the spiral material supply device has: a rod-shaped spiral rotating drive shaft, which is arranged at the lower end of the hopper for storing powder and granular materials, and connected to the drive device; a spiral material conveying blade, which protrudes from the spiral On the rotating drive shaft; a cylindrical material supply cylinder containing the above components. [0003] When using this screw-type material supply device, if the above-mentioned screw rotation drive shaft is rotated, the powdery or granular material stored at the lower end of the above-mentioned hopper is conveyed from the botto...
