Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable pressure choline tablet compression mold. Background Technology

[0002] Choline tablets (usually referring to ursodeoxycholic acid tablets) are prescription drugs used to improve abnormal bile metabolism, dissolve cholesterol gallstones, and treat cholestatic liver disease. Tablet compression molds, also known as tablet compression machine molds, belong to pharmaceutical equipment. They are tools used to manufacture tablets, using the double-sided pressing action of the mold to produce tablets of uniform size and stable quality from raw materials.

[0003] The existing Chinese utility model patent with publication number CN105195618A relates to the field of spare parts processing equipment technology, and particularly to a tablet pressing mold, including a motor, a vibration device, a moving mold, a mold cylinder, an upper pressure plate, a buffer pad, a control box, a length measuring instrument, a lower pressure plate, and a boss. The vibration device is located below the motor, the moving mold is located below the vibration device, the upper pressure plate is located below the moving mold, the lower pressure plate is located below the upper pressure plate, the boss is located below the lower pressure plate, the buffer pad is located below the boss, and the mold cylinder is located on the outer sides of the upper and lower pressure plates. This invention achieves the advantages of small size and high operating efficiency.

[0004] Existing tablet compression molds come in various specifications and sizes, including round, oval, square, and rectangular. Different molds are selected for each tablet's requirements, and different sizes require different molds. This necessitates frequent mold changes when compressing tablets of varying sizes, resulting in low compression efficiency. Applying pressure to the mold during tablet compression is also problematic; insufficient pressure prevents proper compaction, while excessive pressure damages the tablets. Furthermore, the existing molds are manually pressed, making it impossible to accurately adjust the pressure structure, thus preventing the tablets from forming properly.

[0005] Therefore, those skilled in the art have provided adjustable pressure choline tablet compression molds to solve the problems mentioned in the background art. Utility Model Content

The bolt 19 at the upper end of the fixing rod 18 is unscrewed, and the fixing rod 18 is pulled out from the first fixing port 14 and the second fixing port 16. The rotating rod 15 at the upper end of the punch 17 is rotated to disengage it from the mounting port 13. The punch 17 is then replaced to adapt to different tablet shapes.

[0038] Example 2:

[0039] Please see Figure 4-6 This embodiment provides a technical solution based on Embodiment 1:

[0040] The mold inner liner 28 is movably connected to the lower end of the punch 17. The lower end of the mold inner liner 28 is fixedly connected to the mounting plate 29. Insertion rods 30 are installed on both sides of the lower end of the mounting plate 29. Pressing mold three 222 is movably installed at the lower end of the insertion rods 30. The lower end of pressing mold three 222 is movably connected to the base mold two 251.

[0041] Funnel 20 is movably connected to the lower end of punch 17. A fixing plate 21 is installed on the outside of funnel 20. A pressing mold 22 is movably connected to the lower end of funnel 20. An inlet 23 is opened inside the pressing mold 22. Connecting ports 24 are opened on both sides of the pressing mold 22. A base mold 25 is movably connected to the lower end of the pressing mold 22.

[0042] The second pressing mold 221 is movably connected to the lower part of the punch 17. The lower end of the second pressing mold 221 is movably connected to the storage mold 26, and the inner part of the storage mold 26 is fixedly installed with a receiving ring 27.

[0043] Pressing mold 3 222, pressing mold 221 and pressing mold 1 22 are the same module structure, the mold inner liner 28 is a replacement part, the insertion rod 30 and the connecting port 24 form an interlocking connection, and the base mold 2 251 and base mold 1 25 are the same mold.

[0044] The bottom of the funnel 20 is connected to the inlet 23. The upper end of the funnel 20 is conical. The funnel 20 and the base mold 25 are interchangeable parts.

[0045] In this embodiment, pressing mold 1 22, pressing mold 221, and pressing mold 3 222 are the same mold, achieving multiple functions through different configurations. The lower end of pressing mold 1 22 is movably connected to base mold 1 25 for easy quick assembly and disassembly. An inlet 23 is opened inside pressing mold 1 22 for pouring in the powder. The funnel 20 is fixed to the inlet 23 by the outer fixing plate 21. Its conical expansion structure accelerates the introduction of the powder. The powder enters pressing mold 1 22 through funnel 20 and is limited by base mold 1 25. The entire set of molds is placed on the upper end of the placement platform 2. The positioning strip ensures accurate positioning. The punch 17 presses down, and together with the pressure rod 10 and the device plate 11, the tablet forming pressure is completed. The PLC controller controls the process in real time. When adjusting, the mold rotates 180° to replace the pressing mold 22 with the storage mold 26. The diameter of the storage mold 26 is larger than that of the pressing mold 22. The storage mold 26 supports the pressing mold 22 through the internal support ring 27. After replacement, it is rotated again and the punch 17 presses down again to squeeze the tablet out from the inlet 23. When it is necessary to press tablets of different shapes, the punch 17 of different shapes is replaced to press different tablets (the fixing rod 18 and the rotating rod 15 need to be disassembled). The pressing mold 22 is equipped with connecting ports 24 on both sides to connect the inner mold liner 28. The inner mold liner 28 is fixed to the connecting ports 24 through the two side insertion rods 30. The top is pressed by the mounting plate 29 to achieve quick adaptation to different inner cavity shapes.

[0046] The working principle of this utility model is as follows: The lower end of the pressing mold 22 is connected to the base mold 25, and the lower end of the pressing mold 22 is sealed. The medicine powder is poured into the pressing mold 22. The funnel 20 is fixed to the inlet 23 through the outer fixing plate 21. The medicine powder enters the inlet 23 of the pressing mold 22 through the funnel 20. After pouring, the medicine powder is pressed. The pressing mold 22 and the upper structure are placed on the upper end of the placement platform 2. The mold position is determined according to the positioning strip on the upper end of the placement platform 2. After placement, the device is started. The transmission gear 6 is started through the PLC controller 3. The transmission gear 6 is meshed with the moving plate 5, so that the transmission gear 6 can be adjusted in height through the trajectory of the moving plate 5. The transmission gear 6 is fixedly installed with the fixing ring 7. The movement of the fixing ring 7 drives the mounting rings 8 on both sides. The mounting rings 8 are used to move the lower pressure rod 9 in height. The lower pressure rod 9 is connected to the punch 17 through the device plate 11 to press down the mold for initial air release. Then, the PLC controller 3 drives the pressure rod 10 to press down to press down the medicine powder inside the mold. Pressure forming is performed using a pressure sensor inside the mold. This sensor adjusts the pressure at the top of the pressure rod 10 in real time. After the tablets are pressed, they are removed. The user removes the pressing mold 22 from the placement table 2. The pressing mold 22 is then flipped (180°). The base mold 25 of the pressing mold 22 is disassembled and replaced with the storage mold 26. After installation, it is flipped back onto the placement table 2. The punch 17 enters the inlet 23 to eject the tablets. To press tablets into different shapes, the pressing... The mold 22 is equipped with connecting ports 24 on both sides. The mold inner liner 28 is inserted into the inlet port 23, and the insertion rod 30 is inserted and connected to the connecting port 24 to fix the mold inner liner 28. The punch 17 is replaced with the same shape. The user unscrews the bolt 19 from the upper end of the fixing rod 18, and pulls the fixing rod 18 out from the first fixing port 14 and the second fixing port 16, so that the replacement block 12 and the punch 17 can be rotated and disassembled. The punch 17 is rotated and unscrewed from the mounting port 13 in the replacement block 12 through the fixing rod 18 to replace the punch 17.
