[0036] Working principle: When working, the bearing and the idler wheel are placed in the guide rack 33 in the first feeding mechanism 31 and the second feeding mechanism 32 respectively, and then the hydraulic rod 34 is controlled to push the push plate 35 to move. When the push plate 35 moves, the bearing enters between the two storage plates 7, and the idler wheel enters the discharge mechanism 20. Then the drive motor 12 is controlled to work. When the drive motor 12 controls the first gear 14 to rotate through the drive shaft 13, the first gear 14 drives the first rack 15 to move. When the first rack 15 moves, the support rod 9 and the telescopic rod 10 move at the same time. Since the guide column 17 on the telescopic rod 10 moves in the guide groove 16, when the telescopic rod 10 moves to a certain position, the two fixed plates 19 form a one-down and one-up situation, so that the two fixed plates 19 are alternated.

At this time, the two storage plates 7 move away from each other, and the first torsion spring 8 is compressed. When the bearing moves away from the storage plate 7, the bearing enters the upper side of the discharge mechanism 20. At the same time, the bearing is located on the upper side of the idler wheel. As the punching rod 4 is pressed downward, the bearing is pressed into the idler wheel, and then the driving motor 12 rotates again. At this time, the one-way wheel 30 is driven by the second rack 22, so that the second gear 28 drives the gear ring 24 to rotate, and then the multiple rotating plates 25 move away from each other. At this time, the pressed material enters the receiving plate 21, and when the one-way wheel 30 leaves the second rack 22, the second torsion spring 29 is reset, so that the rotating plate 25 is closed again. At this time, another fixed plate 19 moves to the lower side of the storage mechanism 5 again, and this is repeated, so that the equipment is more efficient during processing, and at the same time, the equipment forms a closed-loop automatic processing state, so that the equipment is more efficient during processing, reduces the use of manual labor, and further improves the practicality and convenience of use of the equipment.
