Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0033] Please refer to Figures 1 - 6, in an embodiment of the present invention, the preparation device for the tedizolid phosphate composition tablets includes: an annular plate 3 disposed in a fixed box 1. To support the device and make it more convenient for people to use the device, a plurality of support columns are fixedly installed on the fixed box 1, and the bottoms of the plurality of support columns are respectively fixedly installed with support bottom plates. A discharge pipe is opened at the bottom of the fixed box 1, and the outer wall of the annular plate 3 is in a frustum shape that expands outward from top to bottom. Two mounting plates 4 are fixedly installed on the annular plate 3, and both of the two mounting plates 4 are fixedly connected to the fixed box 1. A lower grinding disc 2 is rotatably installed in the annular plate 3, and the top of the lower grinding disc 2 is in a convex state that slopes upward. Since the top of the lower grinding disc 2 is in a convex state that slopes upward, it is convenient for the raw materials to slide out. An upper grinding disc 5 is arranged on the lower grinding disc 2. The bottom of the upper grinding disc 5 is in a concave state that slopes inward, and a feeding port is opened at the center position of the upper grinding disc 5. Two mounting rods 7 are fixedly installed on the top of the upper grinding disc 5. The tops of the two mounting rods 7 are fixedly installed with a feeding funnel 8, and the discharge port of the feeding funnel 8 communicates with the feeding port. Two cross plates 9 are fixedly installed in the fixed box 1, and both of the two cross plates 9 are located below the lower grinding disc 2. A double-shaft motor 13 is fixedly installed on the two cross plates 9, and one output shaft of the double-shaft motor 13 is fixedly connected to the lower grinding disc 2. By rotating the double-shaft motor 13 to drive the lower grinding disc 2 to rotate, various raw materials are crushed. A funnel-shaped filter screen 10 is fixedly installed in the fixed box 1, and the funnel-shaped filter screen 10 is located below the double-shaft motor 13. The bottom end of the funnel-shaped filter screen 10 is fixedly installed with a Y-shaped discharge pipe 11, and both ends of the Y-shaped discharge pipe 11 extend outside the fixed box 1. The crushed raw materials are filtered through the funnel-shaped filter screen 10. The unqualified raw materials with larger particle sizes that cannot pass through the funnel-shaped filter screen 10 will roll into the Y-shaped discharge pipe 11 and finally be discharged outside the fixed box 1 through the Y-shaped discharge pipe 11.
[0034] To clean the funnel-shaped filter screen 10 and prevent some raw materials from blocking the filter holes and affecting the filtering effect, a connecting rod is fixedly installed on the other output shaft of the double-shaft motor 13. A connecting plate 23 is fixedly installed on the connecting rod. An inclined cleaning brush 12 is fixedly installed on the connecting plate 23, and the bristles on both of the two inclined cleaning brushes 12 are in close contact with the funnel-shaped filter screen 10.
[0035] To limit the upper grinding disc 5, so that when the lower grinding disc 2 rotates, the upper grinding disc 5 always remains in the current non-rotating state, and then the upper grinding disc 5 and the lower grinding disc 2 cooperate to crush various raw materials. Two limiting chutes are opened on the outer wall of the fixed box 1. Two limiting plates 6 are fixedly installed on the outer wall of the upper grinding disc 5, and the two sides of the two limiting plates 6 away from each other respectively extend into the two limiting chutes and are respectively slidably connected to the inner walls of the two limiting chutes.
[0036] In order to keep the fixed box 1 in a vibrating state all the time, so that some powdered raw materials adhered to the fixed box 1 by friction finally slide out of the device, preventing waste of raw materials, a moving gear 14 is fixedly sleeved on the connecting rod. At the bottom of the two cross plates 9, a vertical plate 20 and an L-shaped plate 15 are respectively fixedly installed, and the two L-shaped plates 15 are both located between the two vertical plates 20. Rotating rods 16 are respectively rotatably installed on the two L-shaped plates 15. In order to make the rotating rods 16 rotate more stably on the L-shaped plates 15, rotating holes are respectively opened on the two L-shaped plates 15, and rotating bearings are respectively fixedly installed in the two rotating holes. The two rotating rods 16 respectively penetrate through the two rotating bearings and are respectively fixedly connected with the inner walls of the two rotating bearings. At the bottom ends of the two rotating rods 16, semi-circular gears 17 are respectively fixedly installed, and the two semi-circular gears 17 are both meshed with the moving gear 14. At the top ends of the two rotating rods 16, winding columns 22 are respectively fixedly installed, and winding ropes 19 are respectively fixedly installed on the two winding columns 22. At the ends of the two winding ropes 19 away from each other, impact plates 21 are respectively fixedly installed. Elastic pull ropes 18 are respectively slidably installed on the L-shaped plates 15. In order to reduce the friction between the elastic pull ropes 18 and the L-shaped plates 15, thereby reducing the wear degree of the elastic pull ropes 18 and improving the service life, through holes are respectively opened on the two L-shaped plates 15, and linear bearings are respectively fixedly installed in the two through holes. The two elastic pull ropes 18 respectively penetrate through the two linear bearings and are respectively slidably connected with the inner walls of the two linear bearings. And the ends of the two elastic winding ropes 19 close to each other are respectively fixedly connected with the two impact plates 21. The other ends of the two elastic winding ropes 19 are respectively fixedly connected with the two vertical plates 20.
[0037] The working principle of the preparation device for the tedizolid phosphate composition tablets provided by the present invention is as follows; when this device is needed, various raw materials are poured into the feeding hopper 8, and under the action of gravity, the various raw materials fall into the feeding port and finally enter between the upper grinding disc 5 and the lower grinding disc 2. The double-shaft motor 13 is started, and the rotation of the double-shaft motor 13 drives the lower grinding disc 2 to rotate, thereby crushing the various raw materials. The crushed various raw materials fall onto the funnel-shaped filter screen 10, and the crushed raw materials are filtered through the funnel-shaped filter screen 10. The qualified crushed raw materials with smaller particle sizes will pass through the funnel-shaped filter screen 10, while the unqualified crushed raw materials with larger particle sizes cannot pass through the funnel-shaped filter screen 10 and will roll into the Y-shaped discharge pipe 11 and finally be discharged outside the fixed box 1 through the Y-shaped discharge pipe 11. At the same time, the rotation of the double-shaft motor 13 drives the connecting plate 23 to rotate, and the rotation of the connecting plate 23 drives the inclined cleaning brush 12 to rotate, thereby cleaning the funnel-shaped filter screen 10 to prevent some raw materials from blocking the filter holes and affecting the filtering effect. At the same time, the connecting rod rotates to drive the moving gear 14 to rotate. In the first half of the rotation cycle of the moving gear 14, it drives the semi-circular gear 17 to rotate. The rotation of the semi-circular gear 17 drives the rotating rod 16 to rotate, and the rotation of the rotating rod 16 drives the winding column 22 to wind the winding rope 19, separating the impact plate 21 from the L-shaped plate 15, and at the same time making the elastic pull rope 18 in a stretched state. When the moving gear 14 rotates to the second half of the cycle, it no longer meshes with the moving gear 14. At this time, the elastic pull rope 18 needs to return to its original shape, pulling the impact plate 21 to quickly return to its original position and impact the L-shaped plate 15. In this way, the rotation of the double-shaft motor 13 drives the impact plate 21 to continuously impact the L-shaped plate 15, and the impact force is transmitted to the fixed box 1 through the cross plate 9, so that the fixed box 1 is always in a vibrating state, causing some powdery raw materials adhering to the fixed box 1 by friction to finally slide out of the device, preventing waste of raw materials. People pour such unqualified crushed raw materials with larger particle sizes back into the feeding hopper 8 for re-crushing, so that the particle sizes of the crushed various raw materials are the same, preventing uneven phenomena such as stratification during subsequent stirring and mixing, which may affect the therapeutic effect of the finally pressed tablets.
[0038] Compared with the related technology, the preparation device for the tedizolid phosphate composition tablets provided by the present invention has the following beneficial effects:
[0039] The present invention provides a preparation device for tedizolid phosphate composition tablets. Various raw materials are poured into the feeding funnel 8 and finally enter between the upper grinding disc 5 and the lower grinding disc 2. The lower grinding disc 2 is driven to rotate by the rotation of the double-shaft motor 13 to crush various raw materials. The crushed raw materials are filtered by the funnel-shaped filter screen 10. The unqualified raw materials with larger particle sizes that cannot pass through the funnel-shaped filter screen 10 will roll into the Y-shaped discharge pipe 11 and are finally discharged outside the fixed box 1 through the Y-shaped discharge pipe 11. At the same time, the rotation of the double-shaft motor 13 drives the inclined cleaning brush 12 to rotate to clean the funnel-shaped filter screen 10, preventing some raw materials from blocking the filter holes and affecting the filtering effect. At the same time, it drives the impact plate 21 to continuously impact the L-shaped plate 15, and the impact force is transmitted to the fixed box 1 through the cross plate 9, so that the fixed box 1 is always in a vibrating state, and some powdered raw materials adhering to the fixed box 1 by friction finally slide out of the device, preventing waste of raw materials. People pour such unqualified raw materials with larger particle sizes back into the feeding funnel 8 for re-crushing, so that the particle sizes of various crushed raw materials are the same, preventing uneven phenomena such as stratification during subsequent stirring and mixing, which affects the therapeutic effect of the finally pressed tablets.
