| description | The utility model discloses a novel screw feeding device capable of preventing dead materials, which comprises a variable-pitch screw shaft and a variable-diameter screw blade, the diameter of the screw blade is gradually increased along the material transfer direction, and the pitch of the screw shaft is gradually increased along the material transfer direction. The shaft diameter of the spiral shaft is gradually increased and then gradually decreased in the material conveying direction. An existing equidistant screw is transformed into a variable-pitch screw, and the screw pitch is small in the feeding section, so that the contact face of raw materials and the screw blade is enlarged, the stirring area of the screw blade is enlarged, and a dead material area is prevented from being generated; and the spiral shaft is variable in diameter, so that stable feeding is realized.
