[0030] In this embodiment, the sleeve 62 can slide up and down along the guide rod 61, and at the same time can drive the sliding seat 5 to slide up and down through the driving rod 63, thereby realizing the function of shaking off the powder on the grinding lower plate 2 and the rotating grinding lower plate 21.

[0031] Combine Figure 1-2 As shown, at least one cross bar 7 is provided at the output end of the motor 3, a cross groove 71 is provided in the cross bar 7, a cross groove slide 74 is provided in the cross groove 71, the cross groove slide 74 slides in the cross groove 71, a spring 72 is connected between the cross groove slide 74 and the bottom of the cross groove 71, an end of the cross groove slide 74 away from the cross groove 71 is connected to an abutment block 73, and at least one protrusion 621 is provided on the inner wall of the sleeve 62.

[0032] In this embodiment, the motor 3 is reversed, and the output end of the motor 3 rotates to drive the cross bar 7 to rotate. Under the action of centrifugal force, the cross groove slide bar 74 slides outward along the cross groove 71, and at the same time, the spring 72 is stretched, and the motor 3 is adjusted to increase its speed. At this time, the abutment block 73 abuts against the protrusion 621, and the abutment block 73 drives the sleeve 62 upward under the action of the protrusion 621. When the abutment block 73 passes over the protrusion 621, the sleeve 62 is restored to its original position due to gravity. During this process, the sleeve 62 is shaken, and the powder on the grinding lower plate 2 and the rotating grinding lower plate 21 is shaken to prevent it from adhering to the surface of the grinding lower plate 2 and the rotating grinding lower plate 21.

[0033] Combine Figure 1 As shown, a push rod 11 is provided through the rear side wall of the base 1, and the push rod 11 abuts against the rotating grinding lower plate 21 to prevent the rotating grinding lower plate 21 from rotating downward. A sleeve groove 622 is provided on the sleeve 62, and the push rod 11 slides in the sleeve groove 622.

[0034] In this embodiment, when the rotating grinding lower plate 21 needs to be rotated, the push rod 11 is first pulled out to release the limit on the rotating grinding lower plate 21 so that it can open automatically under the action of gravity.

[0035] Combine Figure 2 As shown, the top rod is C-shaped, with both ends located inside the base.

[0036] Combine Figure 4 As shown, the cross section of the bump 621 is triangular.

[0037] In this embodiment, the triangular protrusion 621 can enable the abutting block 73 to move the sleeve 62 upward after abutting against the protrusion 621 .

[0038] How it works

[0039] When in use, start the motor 3, the motor 3 rotates and drives the connecting rod 43 to slide in the spiral groove 42, and at this time drives the upper grinding plate 4 to rotate and move downward. When the connecting rod 43 is at the end of the spiral groove 42, it drives the motor 3 to rotate synchronously, so that it fits on the grinding lower plate 2 and the rotating grinding lower plate 21 to grind the tablets. After grinding, the motor 3 is controlled to rotate in the opposite direction, and the horizontal groove slide bar 74 is driven to slide outward in the horizontal groove 71 during rotation. At this time, the horizontal groove slide bar 74 drives the abutment block 73 to move toward the protrusion 621, and at the same time increases the speed of the motor 3. When a certain speed is reached, the transverse groove slide bar 74 abuts against the protrusion 621 and drives the sleeve 62 to move upward. After passing over the protrusion 621, the sleeve 62 moves downward under the action of gravity, and the sleeve 62 moves up and down reciprocatingly. The driving rod 63 drives the sliding seat 5 and the grinding lower plate 2 and the rotating grinding lower plate 21 to shake up and down, and the powder attached to the grinding lower plate 2 and the rotating grinding lower plate 21 after grinding is shaken up. When the processing is completed, the top rod 11 is pulled out, and the rotating grinding lower plate 21 rotates downward under the action of gravity to take out the powder located on it.
