Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.
[0024] Such as Figures 1-5As shown in the figure, the utility model provides a technical solution: an antimony-free antifriction material grinding device, which includes a grinding box 1.

One end of the grinding box 1 is connected to the corresponding end of a limiting frame 6. A sliding hole is opened inside the limiting frame 6. The limiting frame 6 is movably connected with the connecting rod 5 through the sliding hole. A return spring 7 is arranged on the outer wall of the connecting rod 5. One end of the return spring 7 is connected to the corresponding side of the connecting block 4, and the other end of the return spring 7 is connected to the corresponding side of the limiting frame 6. One end of the connecting rod 5 is fixedly connected with a rack 8. The rack 8 meshes with a gear 9. The gear 9 is a semi-gear. The inner wall of the gear 9 is in transmission connection with the output end of a first motor 10. The first motor 10 is fixedly connected to one end of the grinding box 1. A guiding hole is opened inside the limiting frame 6. One side of the rack 8 is connected to the corresponding end of a guiding rod 11. The limiting frame 6 is movably connected with the guiding rod 11 through the guiding hole. Two sliding grooves 12 are opened at the top of the grinding box 1. Sliding plates 13 are slidably connected inside the two sliding grooves 12. The tops of the two sliding plates 13 are connected to the bottom of the same moving frame 2. The inner walls of the sliding grooves 12 and the outer walls of the sliding plates 13 are both polished. One side of the grinding box 1 is respectively connected to one ends of two limiting springs 14. The other ends of the two limiting springs 14 are connected to the corresponding side of the same limiting plate 15. By setting the limiting springs 14 and the limiting plate 15, the moving position of the moving frame 2 can be limited, and it can be avoided that the moving frame 2 exceeds the movable range under the action of inertia. The bottom of the grinding box 1 is fixedly connected with a second motor 16. The output end of the second motor 16 is fixedly connected to the bottom end of a rotating rod 17. A fixing ring 18 is fixedly connected to the outer wall of the rotating rod 17. A plurality of grinding rollers 19 are fixedly connected to the outer wall of the fixing ring 18. The bottom of the grinding box 1 is fixedly connected with a bearing seat 21. A bearing 20 is arranged inside the bearing seat 21. The rotating rod 17 is mutually clamped with the bearing seat 21 through the bearing 20.

[0025] The working principle of the present utility model is as follows:
[0026] During use, start the first motor 10. The rotation of the first motor 10 drives the gear 9 to rotate. Since the gear 9 meshes with the rack 8, the rack 8 can be driven to move by the gear 9. The movement of the rack 8 drives the connecting rod 5 to move, and the movement of the connecting rod 5 drives the connecting plate to move. When the connecting plate moves, it will squeeze the return spring 7, causing the return spring 7 to contract. And the movement of the connecting plate will drive the moving frame 2 to move, thereby driving the filter screen 3 to move. Since the gear 9 is a semi-gear, when the gear 9 rotates to a certain angle, it disengages from the rack 8, causing the rack 8 to reset under the action of the return spring 7. By driving the gear 9 to rotate through the first motor 10, the connecting block 4, the connecting rod 5 and the moving frame 2 can be driven to reciprocate through the rack 8, the gear 9 and the return spring 7, thereby driving the filter screen 3 to vibrate. Then, the material flow is filtered through the filter screen 3, so that the material flow enters the grinding box 1. Then, start the second motor 16. The rotation of the second motor 16 drives the rotating rod 17 to rotate. The rotation of the rotating rod 17 drives the fixed ring 18 to rotate. The rotation of the fixed ring 18 drives the grinding roller 19 to rotate. Through the grinding roller 19, the material can be ground. And through an external feeding pump, the ground material can be pumped into the hopper 24 for multiple feeding, so as to achieve the effect of multiple grinding.
