Abstract
The invention discloses a screw type filling machine which comprises a screw, a hopper and a material guide bin arranged on the lower portion of the hopper. The screw is arranged in the hopper and the material guide bin, and the bottom end of the material guide bin is provided with a material discharge metering port. The screw comprises a screw metering portion arranged on the material discharge metering port and a screw stirring portion located above the material discharge metering port. The spiral diameter and the screw pitch of the screw stirring portion are gradually reduced from top to bottom. The spiral diameter and the screw pitch of the screw stirring portion are gradually reduced from top to bottom, and the screw diameter of the upper ring is larger than that of the lower ring, so that extrusion force of spiral grooves to materials is reduced, and the phenomenon that the materials are extruded into blocks is reduced. Due to the fact that the screw pitch of the lower ring is smaller than the screw pitch of the upper ring, the spiral groove on the lower ring can cut and push the materials pushed by the spiral groove in the upper ring, blocked materials which are probably generated when the spiral groove in the upper ring pushes the materials are eliminated, the filling coefficient of the screw is improved, and accuracy of the filling quantity is improved.
