Description

Technical Field

[0001] This utility model belongs to the field of granulation machine technology, and in particular relates to a high-efficiency wet granulation machine for solid dosage form production. Background Technology

[0002] Commonly used solid dosage forms include powders, granules, tablets, capsules, pellets, and films, accounting for approximately 70% of pharmaceutical preparations. Solid dosage forms share the common characteristics of better physical and chemical stability, lower production costs, and greater convenience in administration and portability compared to liquid dosage forms. The preparation process generally employs a wet granulation machine, which is used to grind moist powders into the desired granules, and can also pulverize lumpy dry materials into the required granules. Key features include easy assembly and disassembly of the sieve, with adjustable tension; convenient disassembly and cleaning of the heptagonal roller; and a fully enclosed mechanical transmission system with a lubrication system, ensuring smooth operation of the entire machine.

[0003] In existing high-efficiency wet granulation machines for solid dosage form production, such as the technical solution disclosed in patent application number CN202421268088.0, a storage hopper is provided for easy storage of raw materials. When raw materials need to be added to the granulation box, a stepper motor drives the connecting shaft and the distribution plate to rotate, thereby moving the raw materials between adjacent distribution plates to the top of the discharge port and then falling into the granulation box. At the same time, the amount of raw materials discharged from the surface carried by the distribution plate can be calculated by the number of rotations of the stepper motor, thus improving the efficiency of the device. However, because some raw materials are damp, they easily adhere to the surface of the distribution plate and the inner wall of the feed box, resulting in less raw materials actually entering the granulator. This makes it impossible to achieve accurate measurement and causes inconsistency between the feed and discharge of the granulator. With long-term operation, the amount of raw materials inside the granulator decreases, affecting the granulation process. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figures 1 to 5 As shown, this is an embodiment of the present invention: a high-efficiency wet granulation machine for solid dosage form production, comprising:

[0025] A pellet mill 1 is provided with a feed box 2 and a storage bin 3 is provided on the feed box 2;

[0026] A drive assembly 4 is disposed on the granulator 1, and a rotating component 5 is disposed on the drive assembly 4;

[0027] Driven component 7 is movably connected to drive component 4 and feed box 2. Drive component 4 is provided with feed plate 8.

[0028] In this embodiment, the rotating component 5 divides the inside of the feed box 2 into several non-communicating chambers. The storage bin 3, the feed box 2, and the granulator 1 are sequentially connected. The driving component 4 drives the rotating component 5 to rotate intermittently. The driving component 4 drives the feeding plate 8 to reciprocate linearly through the driven component 7. Raw materials fall from the storage bin 3 into the chambers connected between the feed box 2 and the rotating component 5. When the driving component 4 is activated, it first drives the rotating component 5 to rotate by a preset angle, so that the next chamber is connected to the storage bin 3, and so that another chamber containing raw materials moves to a predetermined position. In this position, the drive assembly 4 no longer drives the rotating part 5 to rotate, allowing sufficient time for the raw material to enter the chamber connected between the feed box 2 and the rotating part 5. At this time, the drive assembly 4 drives the driven assembly 7 to push the feeding plate 8 to move linearly, thereby pushing the raw material in the chamber containing the raw material into the pellet mill 1. After the feeding is completed, the drive assembly 4 no longer drives the rotating part 5 and the driven assembly 7. After a period of time, the drive assembly 4 drives the driven assembly 7 to reset the feeding plate 8, and then the drive assembly 4 drives the rotating part 5 to rotate. This cycle repeats to achieve efficient and precise feeding.

[0029] Please see Figures 1 to 5 In one embodiment of this utility model, the drive assembly 4 includes a motor 41, a first rotating shaft 42, a residual gear 43, a first gear 44, and a second rotating shaft 45. The motor 41 is fixedly connected to the granulator 1 and the first rotating shaft 42. The driven assembly 7 is disposed on the first rotating shaft 42. The first rotating shaft 42 is fixedly connected to the residual gear 43, and the residual gear 43 meshes with the first gear 44. The first gear 44 is fixedly connected to the second rotating shaft 45, and the second rotating shaft 45 is fixedly connected to the rotating component 5.

[0030] In this embodiment, the rotating component 5 includes a rotating column and a partition plate 52. The rotating column is disposed on the driving assembly 4, that is, the rotating column is fixedly connected to the rotating shaft, and the rotating column is fixedly connected to several partition plates 52. The motor 41 drives the residual gear 43 to rotate through the first rotating shaft 42. When the residual gear 43 meshes with the first gear 44, the first gear 44 drives the second rotating shaft 45 to rotate, which in turn drives the rotating column and the partition plates 52 thereon to rotate. Each rotation causes a single empty chamber to rotate to communicate with the feed box 2, and another full chamber to move to the discharge plate 8. When the residual gear 43 separates from the gear, the partition plate 52 remains stationary, which facilitates feeding into the empty chamber and discharging into the full chamber of the discharge plate 8, and has the advantages of efficient and accurate feeding.

[0031] Please see Figures 1 to 5 In one embodiment of the present invention, the drive component 4 is movably connected to the feeding component 6, and the feeding component 6 is movably connected to the feeding box 2.

[0032] In this embodiment, the feeding assembly 6 includes a second gear 61, a third rotating shaft 62, a scraper 63, a limiting disc 64, and a torsion spring 65. The second gear 61 is movably connected to the driving assembly 4, that is, the second gear 61 meshes with the residual gear 43. The third rotating shaft 62 is fixedly connected to the second gear 61 and rotatably connected to the feed box 2. The third rotating shaft 62 is fixedly connected to the scraper 63 and the limiting disc 64. The torsion spring 65 is sleeved on the third rotating shaft 62, and both ends of the torsion spring 65 are fixedly connected to the limiting disc 64 and the feed box 2, respectively. Next, when the drive assembly 4 drives the feeding plate 8 to move linearly and pushes the raw material in the full chamber completely into the pellet mill, the feeding plate 8 and the rotating part 5 remain stationary for a period of time. At this time, the residual gear 43 meshes with the second gear 61, that is, the drive assembly 4 drives the second gear 61 to rotate. The second gear 61 drives the scraper 63 to rotate through the third rotating shaft 62, thereby scraping off the raw material adhering to the feeding plate 8 and sending it into the pellet mill 1. After that, the drive assembly 4 drives the driven assembly 7 to reset, and the residual gear 43 separates from the second gear 61. Under the action of the torsion spring 65, the scraper 63 resets, realizing efficient and accurate feeding.

[0033] Please see Figures 1 to 5In one embodiment of this utility model, the driven component 7 includes a turntable 71, a connecting rod 72, a movable column 73, and a driven column 74. The turntable 71 is movably connected to the driving component 4, the turntable 71 is fixedly connected to the connecting rod 72, the connecting rod 72 is fixedly connected to the movable column 73, the movable column 73 is movably connected to the driven column 74, the driven column 74 is slidably connected to the feed box 2, and the driven column 74 is fixedly connected to the discharge plate 8.

[0034] In this embodiment, the turntable 71 is fixedly connected to the first rotating shaft 42 of the drive assembly 4. The driven column 74 is provided with a first sliding groove 741, a second sliding groove 742, a third sliding groove 743, and a fourth sliding groove 744, which are connected end to end in sequence. The drive assembly 4 drives the turntable 71 to rotate, and the turntable 71 drives the movable column 73 to rotate through the connecting rod 72. When the movable column 73 enters the first sliding groove 741 from the fourth sliding groove 744, the movable column 73 drives the driven column 74 to reset, and the driven column 74 drives the feeding plate 8 to reset. The feeding plate 8 separates from the rotating component 5. When the feeding plate 8 moves to the preset position and no longer interferes with the rotation of the rotating component 5, the movable column 73 enters the second sliding groove 742 from the first sliding groove 741. At this time, the movable column 73 no longer... The driven column 74 moves linearly, and the driving assembly 4 drives the rotating part 5 to rotate by a preset angle. After that, the driving assembly 4 no longer drives the rotating part 5 to rotate, and the rotating part 5 remains stationary, which facilitates feeding into the empty chamber and unloading into the full chamber. At this time, the movable column 73 enters the third slide groove 743 from the second slide groove 742, thereby driving the driven column 74 to move linearly. The driven column 74 drives the feeding plate 8 to push all the raw materials in the full chamber into the pellet mill 1. At this time, the movable column 73 enters the fourth slide groove 744 from the third slide groove 743. At this time, the feeding plate 8 remains stationary, and the driving assembly 4 drives the feeding assembly 6 to rotate to scrape the raw materials attached to the feeding plate 8 into the pellet mill 1. Then the driving assembly 4 separates from the feeding assembly 6, the feeding assembly 6 resets, and the sliding column enters the first slide groove 741 from the fourth slide groove 744. This cycle repeats to achieve efficient and precise feeding.
