Abstract

A conical self-positioning limit feeding device and method. The conical self-positioning limit feeding device has bearing pot, empty circle in the center of bearing pot, U-shaped slide way formed between outer circle and inner circle, rotating evacuation cone and limit feeding rod arranged in the bearing pot and rotate in the same direction, and the speed of the rotating evacuation cone is greater than that of the limit feeding rod; materials are placed in the bearing pot, the evacuation cone rotates, and the materials rotate in the U-shaped slide way of the bearing pot by the torque generated by the friction between rotating evacuation cone and materials, till the long axes of the materials are tangent to the radius of the rotating evacuation cone; the limit feeding rod rotates and pushes materials to exit at equal intervals, thereby achieving the arrangement of the materials in the direction of long axis.

First claim

The invention claimed is:

1. A conical self-positioning limit feeding device, comprising:
a bearing pot, an empty circle being reserved in the center of the bearing pot, a U-shaped slide way being formed between an outer circle and an inner circle, a rotating evacuation cone and a limit feeding rod being arranged in the bearing pot and configured to rotate in the same direction, a rotating speed of the rotating evacuation cone being greater than that of the limit feeding rod;
wherein the bearing pot is configured to receive materials, the rotating evacuation cone is configured to rotate the materials in the U-shaped slide way of the bearing pot to make long axes of the materials tangent to a radius of the rotating evacuation cone under a torque generated by friction between the rotating evacuation cone and the materials;
and the limit feeding rod is configured to rotate and push the materials to an exit at equal intervals, thereby achieving an arrangement of the materials in a direction of the long axes.

2. The conical self-positioning limit feeding device according to claim 1 , wherein the limit feeding rod crosses the U-shaped slide way outside the inner circle of the bearing pot.

3. The conical self-positioning limit feeding device according to claim 1 , wherein the rotating evacuation cone is a cone and is configured to rotate with a center shaft, a bearing outer bearing seat at a top end of the center shaft is connected to evacuation blades, and the evacuation blades are attached to an outer surface of the rotating evacuation cone.

4. The conical self-positioning limit feeding device according to claim 3 , wherein the limit feeding rod is connected to a hollow shaft by a bracket, and the limit feeding rod is configured to rotate with the hollow shaft, and is on the same straight line as a radius of the bearing pot.

5. The conical self-positioning limit feeding device according to claim 4 , wherein rotation centers of the limit feeding rod and the rotating evacuation cone are the same, a pair of bearings are connected to an outside of the center shaft, the hollow shaft is connected to an outside of the bearings, and the center shaft and the hollow shaft are driven by two V-belts with different drive ratios, to achieve different speeds of the shafts in the same direction.

6. The conical self-positioning limit feeding device according to claim 1 , wherein the empty circle is in the middle of the bearing pot, and has a size matching a size of a bottom surface of the rotating evacuation cone, which facilitates an engagement with the rotating evacuation cone.

7. The conical self-positioning limit feeding device according to claim 6 , wherein the U-shaped slide way is composed of two concentric circles and is outside the empty circle, and a width of the U-shaped slide way approximates a length of a short axis of the materials, which facilitates a positioning of the materials in a short-axis direction.

8. The conical self-positioning limit feeding device according to claim 7 , wherein a leak hole is formed at the U-shaped slide way, the materials arrive at a next device through the leak hole, and the leak hole has a size of a largest one of the materials.

9. The conical self-positioning limit feeding device according to claim 1 , wherein a shield is arranged above the leak hole; and
wherein the shield prevents the materials from rolling over, and at the same time blocks the materials on another side that have not reached a desired state and have just been poured into the device above the leak hole from entering a next device accidentally.

10. A control method of the conical self-positioning limit feeding device according to claim 1 , the method comprising:
placing materials in the bearing pot, and controlling the rotating evacuation cone and the limit feeding rod to rotate in the same direction, the rotating speed of the rotating evacuation cone being greater than that of the limit feeding rod;
rotating the rotating evacuation cone, so that the materials rotate in the U-shaped slide way of the bearing pot by the torque generated by the friction between the rotating evacuation cone and the materials, till the long axes of the materials are tangent to the radius of the rotating evacuation cone; and
rotating the limit feeding rod to push the materials to the exit at equal intervals, thereby achieving the arrangement of the materials in the direction of the long axes.
