Description

Technical Field

[0001] This invention relates to the field of pharmaceutical processing equipment technology, and in particular to a controllable tableting device for nabumetone dispersible tablets and the resulting nabumetone dispersible tablets. Background Technology

[0002] Nabumetone dispersible tablets, as a nonsteroidal anti-inflammatory drug, have a wide range of clinical applications, primarily used to relieve pain and inflammation caused by diseases such as osteoarthritis and rheumatoid arthritis. In the production process of nabumetone dispersible tablets, tablet compression is a crucial step, directly affecting the quality, efficacy, and safety of the tablets.

[0003] In the traditional nabumetone dispersible tablet compression process, the processing equipment has few stations and can usually only perform a single tableting operation. This makes it impossible to achieve a continuous processing flow, resulting in a longer production cycle and difficulty in meeting the needs of large-scale production. Furthermore, the existing tableting equipment has relatively fixed tableting specifications, making it difficult to flexibly adjust according to actual production needs. When different specifications of tablets need to be produced, it is often necessary to change the tableting mold and adjust the equipment parameters, which is cumbersome and prone to errors during the adjustment process, affecting the quality stability of the tablets and increasing production and time costs.

[0004] Based on the above reasons, this invention proposes a controllable tableting device for nabumetone dispersible tablets and the resulting nabumetone dispersible tablets, which can effectively improve the processing efficiency and flexibility of nabumetone dispersible tablets through the setting of multiple stations and adjustable components.

[0038] like Figure 1-8 As shown, an embodiment of the present invention provides a controllable tableting device for nabumetone dispersible tablets, including a feed shell 1. A feed pipe 38 is fixedly connected to the center of the top surface of the feed shell 1, and the center of the bottom surface of the feed shell 1 is conical. The feed shell 1 is annularly arranged, and a plurality of vertical pipes 2 are evenly distributed and fixedly connected to the bottom surface. Each vertical pipe 2 is provided with a feed assembly 3. The feed assembly 3 includes a ring gear 16, which is movably connected to the top surface of the feed shell 1, and the inner side of the ring gear 16 meshes with the feed assembly 3. The system comprises several first gears 17, each with a vertical shaft 18 movably connected to the center of its side wall. The vertical shafts 18 are inserted into the inner cavity of the vertical tube 2, and each vertical shaft 18 has a spiral blade 19 fixedly connected to its side wall. A second motor 20 is fixedly installed on the top surface of the feed shell 1, and a round shaft 21 is fixedly connected to the output end of the second motor 20. A second gear 22 is fixedly connected to the round shaft 21, and the second gear 22 meshes with the ring gear 16. A collection shell 4 is installed on the lower side of each vertical tube 2.

[0039] In this embodiment, the raw material for nabumetone dispersible tablets is added into the feed shell 1 through the feed pipe 38. Because the bottom surface of the feed shell 1 is conical, the raw material for nabumetone dispersible tablets can enter each vertical pipe 2. By starting the second motor 20, the second motor 20 drives the second gear 22 to rotate through the round shaft 21. The second gear 22 meshes with the ring gear 16 to rotate. The ring gear 16 meshes with the first gear 17 to rotate. The first gear 17 drives the vertical shaft 18 to rotate. The vertical shaft 18 drives the spiral blade 19 to rotate. The raw material in the vertical pipe 2 is quantitatively added into the inner cavity of the collection shell 4. This can realize multi-station raw material addition operation, and the raw material addition amount is well controllable, improving production quality and efficiency.

[0040] Several collection shells 4 are movably connected to the lower side of the same circular shell 5, and a fixing plate 6 is fixedly connected to the side wall of the collection shell 4. A movable rod 7 is movably connected to the fixing plate 6. A pressure plate 8 is fixedly connected to one end of the movable rod 7 near the circular shell 5, and a first spring 9 is sleeved on the movable rod 7. The two ends of the first spring 9 are fixedly connected to the outer wall of the movable rod 7 and the fixing plate 6, respectively. A controllable adjustment component 10 is provided on the outer wall of the circular shell 5. The controllable adjustment component 10 includes an annular plate 23. The annular plate 23 is provided with... An electric push rod 24 is fixedly connected to the top surface of the annular plate 23 on the lower side of the circular shell 5. The other end of the electric push rod 24 is fixedly connected to the circular shell 5. Several connecting plates 26 are movably connected to the top surface of the annular plate 23. Movable plates 27 are movably connected to the other side of each connecting plate 26. Two round rods 28 are fixedly connected to the movable plates 27. Side plates 29 are movably connected to the side walls of each round rod 28. A first push plate 25 is fixedly connected to the other end of each round rod 28. The side plates 29 are fixedly connected to the circular shell 5.

[0041] In the technical solution of this embodiment, the equipment is first adjusted according to the specifications of the nabumetone dispersible tablets during use. The electric push rod 24 is started, and the electric push rod 24 drives the annular plate 23 to move. The annular plate 23 drives the movable plate 27 to move through the connecting plate 26. The movable plate 27 drives the first push plate 25 to move through the round rod 28, so that the first push plate 25 extends to a suitable length inside the round shell 5. When the collection shell 4 rotates, the movable rod 7 contacts the first push plate 25 and pushes the movable rod 7 with the first push plate 25, and the first spring 9 is compressed. At this time, the movable rod 7 drives the pressure plate 8 to be inserted into the inner cavity of the collection shell 4. The pressure plate 8 compresses the raw material in the inner cavity of the collection shell 4. Because the position of the first push plate 25 is adjusted and the amount of raw material added is determined, the specifications of the tablets compressed by the pressure plate 8 are controllable, which can complete the convenient tableting operation of nabumetone dispersible tablets. After the tablets are made, the pressure plate 8 can move out of the inner cavity of the collection shell 4 under the elastic force of the first spring 9, which facilitates the tableting operation.

[0042] Furthermore, an annular slide rail 36 is fixedly connected to the inner wall of the circular shell 5, and a slider 37 is fixedly connected to the outer wall of each collection shell 4. The slider 37 is movably connected to the annular slide rail 36, which can realize the stable rotation of the collection shell 4 and facilitate production.

[0043] The other end of the collecting shell 4 is provided with a discharge assembly 11. The discharge assembly 11 includes a crossbar 30, which is movably connected to the collecting shell 4. A top plate 31 is fixedly connected to one end of the crossbar 30 in the inner cavity of the collecting shell 4. A second spring 32 is sleeved on the outer wall of the crossbar 30. The two ends of the second spring 32 are fixedly connected to the outer wall of the crossbar 30 and the collecting shell 4, respectively. An annular shell 33 is concentrically fixedly connected to the center of the circular shell 5. Several second push plates 34 are fixedly connected to the outer wall of the annular shell 33. A through groove 39 is opened on the bottom surface of the circular shell 5 at the collecting shell 4.

[0044] In the technical solution of this embodiment, after the tableting operation is completed, the continued rotation of the collection shell 4 can push the second push plate 34 against the crossbar 30 and compress the second spring 32. The crossbar 30 drives the top plate 31 to move in the inner cavity of the collection shell 4. The top plate 31 pushes out the nabumetone dispersion tablets that have been tableted in the inner cavity of the collection shell 4. The pushed-out nabumetone dispersion tablets are discharged through the through groove 39, thus completing the process of tableting preparation of nabumetone dispersion tablets. The preparation efficiency is high.

[0045] Furthermore, the number of the first push plate 25, the second push plate 34, and the collection shell 4 are the same, and the side walls of the first push plate 25 and the second push plate 34 are both arc-shaped. The movable rod 7 is fixed with a roller 35 at the end away from the pressure plate 8, and the cross bar 30 is fixedly connected with another roller 35 at the end away from the top plate 31, so that the movable rod 7 can be pushed by the first push plate 25 to complete the tablet pressing operation, and the cross bar 30 can be pushed by the second push plate 34 to complete the material discharge operation.

[0046] Furthermore, a rotary drive assembly 12 is provided at the center of the bottom surface of the circular shell 5. The rotary drive assembly 12 includes a first motor 13, which is fixedly installed at the center of the bottom surface of the circular shell 5. The output end of the first motor 13 is fixedly connected to a main shaft 14. The main shaft 14 passes through the circular shell 5 and is fixedly connected to a connecting frame 15. The connecting frame 15 is fixedly connected to the feed shell 1.

[0047] In the technical solution of this embodiment, during processing, the first motor 13 is started by an external power source. The first motor 13 drives the main shaft 14 to rotate, the main shaft 14 drives the connecting frame 15 to rotate, and the connecting frame 15 drives the feed shell 1 to rotate. The rotation of the feed shell 1 allows the raw material to enter the vertical pipe 2 better, facilitating the raw material filling operation. On the other hand, it can drive the collecting shell 4 to rotate, thereby completing the tableting and discharging operations at multiple stations and improving the processing efficiency.
