Detailed Description

Referring to fig. 1-5, a feeding extruder comprises a cylinder body 1, feeding paddles 2, a feeding driving motor 3 and an extruding mechanism 4, wherein the extruding mechanism 4 is arranged at the lower end inside the cylinder body 1, two feeding paddles 2 are arranged at the lower end inside the cylinder body 1 and above the extruding mechanism 4 in a design mode, the two feeding paddles 2 are rotatably arranged in the cylinder body 1, the two feeding driving motors 3 are arranged at the outer side of the cylinder body 1 in a design mode, the two feeding driving motors 3 are respectively connected with the feeding paddles 2 in a driving mode, each feeding paddle 2 comprises a paddle shaft 21 and paddles 22, four paddles 22 are arranged, an interval between every two adjacent paddles 22 is 90 degrees, each paddle 22 is arranged at the other end of the paddle shaft 21 in a surrounding mode from one end of the paddle shaft 21, and two end portions of each paddle 22 are twisted by 90 degrees. Four paddles are designed and are spaced at 90 degrees, each paddle is twisted by 90 degrees, and continuous extrusion feeding can be realized just by the interaction of the two paddles; the both ends structural design of paddle is perpendicular with the cylinder body, and both sides paddle can scrape the material above the curb plate of cylinder body, prevents the material adhesion. Through the action of the feeding paddles, the speed of the material entering the extrusion mechanism is increased, and the extrusion efficiency is improved.

The paddles 22 of the two feeding paddles 2 are twisted and installed towards the middle at the same time, and the two feeding driving motors 3 drive and control the two feeding paddles 2 to rotate towards the middle at the same time. The paddles of the two feeding paddles can be installed in a staggered manner according to the assembly relation, so that the interference of the paddles of the two feeding paddles is avoided; the one end that the paddle warp earlier is kept away from the export of extrusion mechanism, and the one end that the paddle warp after is close to the export of extrusion mechanism, and two feeding paddles simultaneously rotate the extrusion material to the centre like this, and the one end that keeps away from extrusion mechanism extrudees the material forward downwards earlier, along with rotating, two feeding paddles from back to forward in proper order the extrusion feed downwards.
