Preferably, the feeding mechanism comprises a hopper, an inner layer, a helical blade and an outer layer, wherein the inner layer is fixed at the lower end of the hopper, the outer layer is fixed on the shell, and the outer layer and the inner layer are connected together through the helical blade and form an effective helical exhaust channel.

Preferably, the spiral conveying shaft is divided into a conveying section, a grinding section and an output section from left to right, a circular blocking piece is arranged in an area between every two spiral pieces of the grinding section, and a through hole is formed in the circular blocking piece.

Preferably, the opening includes first opening, first opening sets up the center department at circular blocking piece, it has a plurality of second openings to distribute along the annular on the circular blocking piece, and the second opening uses first opening to distribute the setting as the centre of a circle annular.

Preferably, a hopper cover is arranged at the top end of the hopper.

Preferably, two supporting plates are symmetrically arranged at the top of the bottom plate, and the tops of the supporting plates are connected with the shell.

The invention has the beneficial effects that:

according to the invention, when the material is fed into the hopper from the feeding port of the hopper, the hopper cover and the hopper are sealed, and after the material is fed into the hopper, the material enters the feeding port of the extruder through the inner layer; when hot gas in the extruder cylinder body returns to the hopper, the hot gas can be discharged along a channel between the inner layer and the outer layer due to the blockage of the inner layer wall, and the powder is prevented from being sprayed out of the helical blade channel due to the blockage of the helical blade;

when the output material, probably having the raw meal along with, in order to avoid the raw meal to flow out, transversely weld the circular separation blade between the flight on grinding the section, after the raw meal is blockked, for the grog flows out, have on the circular separation blade to be provided with the opening, set the opening into first opening and second opening component mode for the grog flows out from first opening and second opening, and the raw meal is blockked, at last through output section output banding plastics, later by cooling, cutting processing.
