[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution for a feeding device of a pill polishing machine.

[0023] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4The feeding device of a pill polishing machine comprises a fixed frame 1 and a plurality of shot blasting machine hoppers 10. A belt conveyor for conveying pills is provided inside the fixed frame 1. The belt conveyor is composed of a roller, a conveying belt and a driving motor. The pills falling on the belt are conveyed by the conveying belt. The fixed frame 1 is provided with a plurality of discharge notches 11 corresponding to the shot blasting machine hoppers 10. The pills conveyed on the belt can fall into the interior of the shot blasting machine hopper 10 through the discharge notch 11. The interior of the discharge notch 11 is hinged with a movable plate 2 for blocking the discharge notch 11 through a pin shaft. A torsion spring for driving the movable plate 2 to flip open is sleeved on the pin shaft of the movable plate 2. The discharge notch 11 is blocked by the movable plate 2 to prevent the pills from flowing out through the discharge notch 11. When the movable plate 2 is not under force, the torsion spring rebounds to make the movable plate 2 flip over to open the discharge notch 11.

[0024] Please refer again Figure 1 、 Figure 2 and Figure 4 When the lifting seat 3 is lowered, the bottom of the blocking rod 32 falls on the belt to limit the pills from continuing to be transported forward and guide the pills to be discharged to the discharge notch 11. The bottom of the connecting slide 31 is fixedly connected to the bottom of the connecting slide 31, and the top of the bottom film 33 is fixedly connected to a tension spring 34. The other end of the tension spring 34 is fixedly connected to the fixed block, and the tension spring 34 is sleeved on the connecting slide 31. When the lifting seat 3 is lowered, the tension spring 34 is stretched. When the top of the lifting seat 3 is not under force, the lifting seat 3 is quickly driven up by the rebound of the tension spring 34.

[0025] Please refer again Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A baffle rod 4 is fixedly connected to the connecting slide rod 31 to limit the flipping of the movable plate 2. The baffle rod 4 is L-shaped, and one end of the baffle rod 4 is tightly set against the movable plate 2. One end of the baffle rod 4 is against the movable plate 2 to limit the flipping of the movable plate 2 to open the discharge gap 11. When the baffle rod 4 descends, the movable plate 2 flips open. When the baffle rod 4 rises, one end of the baffle rod 4 pushes the movable plate 2 to flip close again.

[0026] Please refer again Figure 1 and Figure 2The top of the fixed frame 1 is fixedly connected to two connecting frames 5, and a fixed slide bar 6 is fixedly connected between the two connecting frames 5. An extrusion rod 7 is slidably connected to the fixed slide bar 6. The top of each lifting seat 3 is fixedly connected to a raised block 9. The longitudinal section of the raised block 9 is an isosceles trapezoidal shape. The bottom of the extrusion rod 7 is rotatably connected to a roller. By controlling the extrusion rod 7 to slide horizontally on the fixed slide bar 6, when the bottom of the extrusion rod 7 slides to the raised block 9, the extrusion rod 7 squeezes the raised block 9 to push the lifting seat 3 down. Under the action of the extrusion rod 7 and the raised block 9, the single lifting seat 3 is pushed down. An adjusting screw 8 is rotatably connected between the two connecting frames 5, and the extrusion rod 7 is threadedly connected to the adjusting screw 8. A motor 81 that drives the adjusting screw 8 to rotate is fixedly connected to the connecting frame 5. By starting the motor 81 to drive the adjusting screw 8 to rotate, the extrusion rod 7 slides on the fixed slide bar 6 to adjust the position of the extrusion rod 7.

[0027] Working principle: the pills to be fed fall on the belt for transportation. When the extrusion rod 7 is controlled to slide to the top of the first raised block 9 by starting the motor 81, the raised block 9 is pushed by the extrusion rod 7 to squeeze the lifting seat 3 down, so that the blocking rod 32 falls on the belt to block the pills for transportation, and the baffle rod 4 is driven to fall when the connecting slide bar 31 slides downward, releasing the obstruction to the movable plate 2 so that the movable plate 2 flips over to open the discharge gap 11, and under the guidance of the blocking rod 32, the pills transported on the belt pass through the discharge gap 11 and fall into the inside of the shot blasting machine hopper 10. Similarly, by controlling the extrusion rod 7 to slide on the fixed slide bar 6, the extrusion rod 7 squeezes the raised blocks 9 at different positions to open multiple discharge gaps 11 in turn, so that the pills fall into multiple shot blasting machine hoppers 10 in turn, thereby achieving automatic and orderly feeding.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
