[0038] To facilitate thorough crushing of the tablets and improve the quality of tablet crushing, a sliding groove plate 22 is fixedly connected inside the frame 6. A rack rod 15 is slidably arranged inside the sliding groove plate 22. A gear 18 is meshed with one side of the rack rod 15. A crushing disc 20 is fixedly connected above the gear 18. A receiving disc 19 is engaged inside the crushing disc 20.

[0039] Furthermore, in order to facilitate the improvement of tablet crushing efficiency and the smoothness of the crushing mechanism during operation, the surface of the crushing disc 20 is provided with a shell 13, the shell 13 is fixedly connected to the working box 1, the rack 15 is slidably connected to the shell 13, and a circular arc rod 14 is fixedly connected to one side of the support plate 8, and a striking ball 21 is fixedly connected to one end of the circular arc rod 14.

[0040] To facilitate the crushing of multiple groups of tablets in batches and avoid insufficient crushing, the frame 6 is rotatably connected to the working box 1 via a pin. The other end of the arc rod 14 is provided with a push rod 16, which is slidably connected to the working box 1. A baffle 17 is fixedly connected to the surface of the push rod 16, and a placement chamber 12 is slidably connected to the surface of the baffle 17. One end of the placement chamber 12 is connected to the interior of the outer shell 13.

[0041] Furthermore, in order to improve the efficiency of tablet crushing and the quality of the crushed powder, the placement chamber 12 is fixedly connected to the working box 1, and the upper surface of the support plate 8 is provided with a limit rod 11 through a pulley. The limit rod 11 is fixedly connected to a rotating wheel 2, which is threadedly connected to the working box 1, and the rack rod 15 is slidably connected to the working box 1.

[0042] To facilitate the removal of the powder by medical staff, the inside of the crushing disc 20 is provided with several sets of through holes. The sliding positions of the rack rod 15 and push rod 16 with the working box 1 are all equipped with reset elements, and the striking ball 21 is located on the left side of the placement chamber 12.

[0043] To improve the stability of the device during operation, a groove is provided inside the slide plate 22, one end of the rack rod 15 slides in the groove, and the crushing disc 20 rotates inside the outer shell 13.

[0044] To facilitate improving the service life of some parts in this device, the striking ball 21 is made of rubber, the placement chamber 12 is made of a lighter material, and the pressure plate 10, the outer shell 13 and the crushing plate 20 are all made of high-hardness materials.

[0045] Furthermore, the baffle 17 is made of a highly wear-resistant composite material, a block is provided at the connection position between the rack rod 15 and the crushing disc 20, and the gear 18 is rotatably connected to the outer shell 13.

[0046] The working principle and usage process of this utility model are as follows: After the utility model is installed, the medicine receiving tray 19 is first inserted into the crushing tray 20 through the working port on the side of the working box 1. When it is necessary to crush children's tablets, the medical staff directly put the tablets on the medicine plate into the placement chamber 12 to avoid direct contact between the medical staff and the tablets, which can reduce the contamination of the crushed powder. After the tablets are put into the placement chamber 12, they will fall onto the surface of the baffle 17. At this time, the electric motor 3 is started to rotate, which drives the rotating shaft 4 to rotate. The rotating shaft 4 rotates, which drives the turntable 5 to rotate. The rotation of the turntable 5 will push the cooperating frame 6 and the swing rod 7 to swing through the pulley. When the swing rod 7 swings, it pushes the support plate 8 to swing through the pin. When the support plate 8 swings, it will drive the pressure rod 9 to move up and down through the pin. The movement of the pressure rod 9 will drive the pressure plate 10 to move inside the outer shell 13, which can impact and crush the tablets inside.

[0047] When the support plate 8 swings, it will cause the arc rod 14 to swing. The swing of the arc rod 14 will cause the striking ball 21 to strike the side of the placement chamber 12, which can effectively prevent the blockage after the tablets are put into the placement chamber 12 and improve the stability of tablet crushing. At the same time, the swing of the arc rod 14 will push the push rod 16 to slide on the side of the working box 1. The sliding of the push rod 16 can cause the baffle 17 to slide inside the placement chamber 12, which can make the tablets intermittently fall through the placement chamber 12 onto the surface of the crushing disc 20 inside the outer shell 13, which is convenient for crushing the tablets below and prevents insufficient crushing after adding tablets, thus improving the crushing quality.

[0048] When the frame 6 swings, it drives the slide plate 22 to swing. When the slide plate 22 swings, it pushes the rack rod 15 to move left and right inside the working box 1 through the slide groove. The movement of the rack rod 15 meshes and drives the gear 18 to rotate. The rotation of the gear 18 drives the crushing disc 20 to rotate, which can improve the crushing effect of the tablets and crush the tablets thoroughly. When the crushing disc 20 is rotating, the pressure plate 10 continuously crushes the tablets on its surface. This allows some of the crushed powder to fall through the through hole onto the surface of the receiving disc 19 inserted inside the crushing disc 20 for collection. At the same time, it can mix various crushed powders in advance, which can effectively reduce the workload of medical staff and improve crushing efficiency.

[0049] Meanwhile, when crushing tablets of different thicknesses, the operator rotates the rotating wheel 2 to drive the limiting rod 11 to swing. The swing of the limiting rod 11 will drive the pulley to move on the upper surface of the support plate 8, so that the pulley below the limiting rod 11 is located at different positions on the upper surface of the support plate 8. The swing amplitude of the support plate 8 can be adjusted, thereby controlling the height of the pressure rod 9 when it moves up and down. It can crush tablets of different thicknesses and sizes, and has a wide range of applications.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
