[0027] Embodiment 2

[0028] Based on Example 1, please refer to the attached Figure 1 A brush plate 12 that cooperates with the screening net 7 is fixedly connected to one side of the rotating shaft 8 .

[0029] In specific use, the sealing cover 13 is opened, and the tablets to be crushed are placed in the feed tube 11, and the tablets fall on the upper end of the baffle plate 22. At this time, the end faces of the baffle plate 22 are close to the inner walls of the feed tube 11 on both sides, and the ends of the sealing blocks 24 on both sides are close to the other two inner walls of the feed tube 11, thereby achieving the blocking of the feed tube 11. When it is necessary to add material to the crushing box 10, the third motor 26 is started to drive the baffle plate 22 to flip ninety degrees, and the tablets fall from the two sides of the baffle plate 22 into the crushing box 10. The third motor 26 is started again to flip ninety degrees. When the sealing blocks 24 on both sides contact the inner walls of the feed tube 11 on both sides, the sealing blocks 24 are squeezed to slide into the slot 23 and the fixing spring 25 is squeezed to undergo compression deformation. When the baffle plate 22 is rotated to be perpendicular to the inner wall of the feed tube 11, the feed tube 11 is blocked again.

[0030] Under the guidance of the unloading inclined plates 27 arranged in an "inverted eight" shape on both sides, the tablets fall between the two electric crushing rollers 21, and are crushed into powder under the squeezing of the two electric crushing rollers 21 and fall onto the sieve net 7. The first motor 9 is started to drive the rotating shaft 8 to rotate, and the rotating shaft 8 drives the crushing box 10 to rotate, so that the powder is evenly sprinkled on the sieve net 7. The second motor 15 is started to drive the rocker 16 to rotate, and the rocker 16 drives the eccentric cam 14 to rotate. With the cooperation of the vibration spring 18, the sieve tank 3 vibrates reciprocatingly up and down, so that the powder falls from the mesh of the sieve net 7 and flows out from the discharge pipe 5. At the same time, under the rotation of the rotating shaft 8, the brush plate 12 cleans the sieve net 7 to prevent the mesh from being blocked.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
