Description

Technical Field

[0001] This invention relates to the field of tablet press technology, specifically a tablet press for producing dispersible tablets. Background Technology

[0002] A tablet press is a device used to compress powdered or granular materials into tablets, widely used in pharmaceuticals, food, chemicals, and other industries. Tablet presses can produce round, irregularly shaped, and dispersible tablets with a diameter not exceeding 13mm. The working process of a tablet press includes steps such as the lower punch sealing the bottom of the die hole, the feeder filling the powder, the upper punch pressing the powder downwards, the upper punch lifting out of the hole, and the lower punch ejecting the tablet. Dispersible tablets are made by compressing powder, and a tablet press is needed to compress the powder into tablets during the production of dispersible tablets. Therefore, we have introduced a tablet press for dispersible tablet production.

[0003] An existing patent (publication number: CN118991122A) discloses a folic acid tablet compressor, including a fixed base, a support platform fixedly mounted on the top of the fixed base, a worktable mounted inside the support platform, a pressing hole in the worktable, a feeding component mounted on one side of the worktable, a hydraulic rod mounted on the top of the worktable, and a pressure plate connected to the movable end of the hydraulic rod. The invention also includes a finished product platform, a rotatable bottom of the worktable, and a cleaning component positioned between the hydraulic rod and the pressure plate. This invention, by mounting a cleaning component on the pressure plate and placing the finished product platform at the bottom of the worktable, allows the tablet to be compressed successfully. After compression, rotating the finished product platform aligns the drop opening with the pressing hole. The pressure plate then continues to move downwards, pushing the dispersible tablets into the drop channel. Simultaneously, as the pressure plate moves downwards, a cleaning roller extends into the pressing hole. A drive component and a reciprocating motion component drive the cleaning roller to rotate and move up and down, cleaning the inner wall of the pressing hole. The existing technology has the following problems: After one tableting operation, powder will adhere to the end faces of the upper and lower punches of the existing tableting machine, resulting in sticking. This powder is carried into the next tableting operation, which can easily lead to component mixing and thus affect the quality of the final tablet. In addition, sticking will increase the breakage rate of the dispersible tablets. Summary of the Invention

The horizontal push rod slides through the vertical plate and is connected to an arc-shaped push rod.

[0010] Preferably, the transition section consists of solid sections at both ends and a spring telescopic rod in the middle.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] This invention uses a support shaft within an indexing mechanism to drive the tableting table to rotate intermittently, 90° each time. The motor output in the indexing mechanism drives a pulley in the transmission mechanism to rotate, which in turn drives the tableting mechanism. The two extrusion plates in the tableting mechanism move asynchronously, extruding the powder in the lower tableting groove. As the extrusion plates move upward, they also cause the cleaning brush in the cleaning mechanism to automatically move below the extrusion plates, brushing away the powder adhering to the bottom surface of the extrusion plates. This achieves automatic cleaning of the extrusion surface after each extrusion, preventing the adhering powder from causing contamination in the next extrusion and reducing the breakage rate during the next molding.

[0019] The invention also drives the material handling mechanism through the transmission mechanism. The material handling mechanism can automatically push the formed dispersible tablets out of the tableting groove, and then use a cam to squeeze the trigger ball. Finally, the trigger ball pushes the arc-shaped push rod to push the dispersible tablets off the tableting table, completing the automatic unloading.

[0020] The present invention can also drive the feeding mechanism through the transmission mechanism. The crushing rod in the feeding mechanism can automatically crush the lumpy powder in the storage box. When the spiral blade rotates, it will transport the powder in the storage box downward and automatically fall into the tableting groove to realize automatic feeding. This is to prevent the spiral blade from starting to rotate and feed the powder before the next tableting groove has rotated to the bottom of the storage box during the rotation of the tableting table, so that the powder falls on the top surface of the tableting table other than the tableting groove.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 12 The present invention provides a technical solution: a tablet press for dispersible tablet production, comprising a base 1, a gantry frame 2 integrally formed on the top edge of the base 1, a bearing frame 10 integrally formed in the middle of the bottom surface of the base 1, an indexing mechanism 4 provided in the middle of the bearing frame 10, a tablet pressing table 5 fixedly connected to the top of the indexing mechanism 4, an mounting baffle 11 fixedly connected to one side of the top surface of the base 1, a transmission mechanism 6 rotatably connected to the middle of the mounting baffle 11, the transmission mechanism 6 being connected to the tablet pressing mechanism 7, cleaning mechanisms 8 provided on both sides of the tablet pressing mechanism 7, a feeding mechanism 9 fixedly installed on the top rear side of the gantry frame 2, and a material picking mechanism 3 movably connected to one side of the tablet pressing mechanism 7.

[0036] In this embodiment, as Figures 1 to 2 and Figures 5 to 7As shown, the tablet pressing mechanism 7 includes a reciprocating rotating plate 701 rotatably connected between the front and rear sides of the gantry 2 via a connecting shaft. Hinged arms 702 are rotatably connected to the middle of both sides of the reciprocating rotating plate 701 via connecting shafts. An extrusion plate 703 is rotatably connected to the bottom end of the hinged arms 702. A mounting groove 704 is formed in the middle of the bottom surface of the reciprocating rotating plate 701. A horizontal shaft 705 is rotatably connected between the two inner walls of the mounting groove 704. An arched component 706 is integrally formed on the outer surface of the horizontal shaft 705. A connecting ball 707 is rotatably connected to the middle of the arched component 706. The connecting ball 707 is movably embedded in the offset... The top edge of the mandrel 708 is higher than the bottom edge of the eccentric wheel 708. A drive shaft 709 is fixedly connected to the center of the bottom surface of the eccentric wheel 708. A bending rod 7010 is fixedly connected to the top edge of the extrusion plate 703. A limiting clamping block 7011 is integrally formed in the center of the bending rod 7010. The limiting clamping block 7011 slides against both sides of the limiting strip 7012. A limiting groove is opened in the center of the limiting strip 7012, and the bending rod 7010 slides through the center of the limiting groove. The bending rod 7010 is divided into two groups, left and right. The left group of bending rods 7010 is connected to the material handling mechanism 3 and the cleaning mechanism 8. The right-side bending rod 7010 is only connected to the cleaning mechanism 8. When the drive shaft 709 rotates under the drive of the transmission mechanism 6, the drive shaft 709 will drive the eccentric wheel 708 at the top to rotate eccentrically. The eccentric wheel 708 will then drive the arched part 706 to move through the connecting ball 707 at the top. When the arched part 706 moves, it will rotate around the horizontal axis 705. At the same time, when the eccentric wheel 708 rotates, its highest point on the top surface will make a circular motion. Therefore, when the highest point on the top of the eccentric wheel 708 rotates, it will also squeeze the reciprocating plate 701 and the gantry frame. The connecting shaft between 2 rotates back and forth, that is, the left and right ends of the reciprocating rotating plate 701 move asynchronously. When the reciprocating rotating plate 701 moves asynchronously to the left and right, it will drive the hinge arm 702 to move synchronously. The movement trajectory of the hinge arm 702 is an arc. The hinge arm 702 will drive the extrusion plate 703 at the bottom to move in an arc. Since the extrusion plate 703 slides against the limit clamp 7011 in the middle of the top bending rod 7010 on both sides of the limit strip 7012, it can maintain the vertical lifting and lowering of the extrusion plate 703, thereby extruding the powder in the tableting groove 501 directly below.

[0037] In this embodiment, as Figure 8 and Figure 9As shown, the cleaning mechanism 8 includes a lifting plate 801 fixedly connected to the front side of the bending rod 7010. A sloping groove 802 is provided in the middle of the lifting plate 801, and a translation rod 803 slides through the middle of the sloping groove 802. A limiting slider 804 is integrally formed at one end of the translation rod 803 near the edge of the base 1. The limiting slider 804 is slidably connected inside a horizontal limiting groove 805, which is located in the middle of the fixed plate 806. A support plate 807 is fixedly connected to one end of the translation rod 803 near the middle of the base 1. A spring telescopic rod 808 is fixedly connected to the top surface of the support plate 807, and a cleaning brush 809 is fixedly connected to the top of the spring telescopic rod 808. When the pressure plate 7010 is squeezed... When the 03 moves upward, the bending rod 7010 drives the lifting plate 801 to rise synchronously. When the lifting plate 801 moves upward, the inclined groove 802 squeezes the translation rod 803 to move. The translation rod 803 drives the limiting slider 804 to move synchronously. The limiting slider 804 slides along the horizontal limiting groove 805 to the rear side of the base 1. During this process, the translation rod 803 drives the support plate 807 to move synchronously. The support plate 807 drives the cleaning brush 809 to move through the spring telescopic rod 808 on the top surface. During the movement of the cleaning brush 809, the squeezing plate 703 also moves upward. At this time, the bristles of the cleaning brush 809 contact the bottom surface of the squeezing plate 703 to clean the bottom surface of the squeezing plate 703.

[0038] In this embodiment, as Figure 2 , Figure 3 and Figure 11As shown, the tableting table 5 includes a tableting groove 501 formed on the top edge. A limiting ring 502 is integrally formed on the inner wall of the tableting groove 501. A pad 503 is movably attached to the top surface of the limiting ring 502. A rebound spring 504 is fixedly connected to the center of the bottom surface of the pad 503. The bottom end of the rebound spring 504 is fixedly connected to the inner bottom surface of the tableting groove 501. An annular groove 505 is formed on the bottom surface of the tableting table 5, located below the bottom surface of the tableting groove 501. A feeding slide 506 is provided on the left side of the tableting table 5, and the feeding slide 506 is fixedly connected to the top surface of the base 1 by a support rod. The tableting table 5 rotates intermittently under the drive of the indexing mechanism 4, rotating 90° each time. Taking one tableting groove 501 as an example, during tableting... Initially, the tableting groove 501 is located directly below the feeding mechanism 9. The feeding mechanism 9 adds powder into the tableting groove 501. Then, the indexing mechanism 4 drives the tableting table 5 to rotate 90°, rotating the tableting groove 501 to below the right extrusion plate 703. The right extrusion plate 703 pre-compresses the powder in the tableting groove 501. At this time, the left extrusion plate 703 moves in the opposite direction to the right extrusion plate 703, that is, the left extrusion plate 703 moves upward. After the pre-compression is completed, the indexing mechanism 4 drives the tableting table 5 to rotate 90° twice more until the tableting groove 501 moves to below the left extrusion plate 703. The left extrusion plate 703 then compresses the powder in the tableting groove 501 again, achieving double compression and better molding effect.

[0039] In this embodiment, as Figure 3 , Figure 4 and Figure 6As shown, the material handling mechanism 3 includes a transition section 301 fixedly connected to the end of the bending rod 7010 away from the middle of the base 1 and a vertical plate 302 fixedly connected to the bottom surface of the mounting plate 11. A lifting rod 303 is fixedly connected to the bottom end of the transition section 301. A return spring 304 is fixedly connected to the side of the vertical plate 302 near the middle of the base 1. The end of the return spring 304 away from the vertical plate 302 is connected to a trigger ball 305 through a circular plate. The outer surface of the trigger ball 305 near the vertical plate 302... The device is integrally molded with a horizontal push rod 306, which slides through the vertical plate 302 and is connected to the arc-shaped push rod 307. A cam 308 is provided on the right side of the trigger ball 305, and the cam 308 is connected to the drive shaft 709. The transition section 301 consists of solid sections 301a at both ends and a spring telescopic rod 301b in the middle. The lifting rod 303 is divided into a horizontal section and a vertical section, with the vertical section located below the annular groove 505, and the central axis of the vertical section aligned with the pressing groove 505 directly above it. The central axes of 01 coincide; when the left extrusion plate 703 moves upward, it will drive the connected transition section 301 to move upward. The transition section 301 drives the lifting rod 303 to move upward. The lifting rod 303 passes through the annular groove 505 and inserts into the tablet pressing groove 501, and lifts the pad 503 from bottom to top. During this process, the pad 503 will lift the dispersed tablets pressed on the top surface to the outside of the tablet pressing groove 501. At this time, the motor 401 will also drive the cam 308 to extrude through the transmission mechanism 6. The trigger ball 305 pushes the arc-shaped push rod 307 through the horizontal push rod 306 to push the dispersed tablets ejected from the tableting groove 501 from the tableting table 5 and slide them into the unloading slide 506. This structure can realize automatic material picking, mainly by utilizing the rotation of the indexing plate 405 and the drive plate 402 in the indexing mechanism 4. For every rotation of the drive plate 402, the indexing plate 405 rotates a quarter rotation. That is, for every rotation of the cam 308, the tableting table 5 only rotates a quarter rotation.

[0040] In this embodiment, as Figure 12 As shown, the indexing mechanism 4 includes a motor 401. The output end of the motor 401 passes through a drive disk 402 and a crescent-shaped disk 403 sequentially from bottom to top. An actuating post 404 is integrally formed on the top surface of the drive disk 402. An indexing disk 405 is slidably attached to one side of the crescent-shaped disk 403. Actuating grooves 406 and arc-shaped grooves 407 are alternately distributed along the edge of the indexing disk 405. A support shaft 408 is fixedly connected to the center of the indexing disk 405. The motor 401 drives the drive disk 402... When the 02 and the crescent-shaped disk 403 rotate, the long arc surface of the crescent-shaped disk 403 fits into the arc groove 407, which can limit the indexing disk 405. When the actuating column 404 enters the actuating groove 406, it will drive the indexing disk 405 to rotate. Each rotation angle is 90°. The indexing disk 405 drives the pressing table 5 to rotate through the support shaft 408. The output end of the motor 401 is connected to the transmission mechanism 6, thereby driving the drive shaft 709 to rotate through the transmission mechanism 6.

[0041] In this embodiment, as Figure 11 As shown, the transmission mechanism 6 includes a pulley 601 fixedly connected to the output end of the motor 401. The pulley 601 is connected to a second pulley 602 via a synchronous belt. A main shaft 603 is fixedly connected to the middle of the second pulley 602, and a third pulley 604 is fixedly connected to the top of the main shaft 603. The third pulley 604 and a double pulley 605 form a transmission structure via a synchronous belt. The double pulley 605 is connected to a fourth pulley 606 via a synchronous belt. The drive shaft 709 rotates through the middle of the mounting plate 11. The pulley 605 is penetrated by the drive shaft 709; the adjacent pulleys in the transmission mechanism 6 form a transmission structure through the synchronous belt. The pulley 601 drives the pulley 602 to rotate through the synchronous belt. The pulley 602 drives the pulley 604 to rotate through the main shaft 603. The pulley 604 drives the double pulley 605 to rotate through the synchronous belt. The double pulley 605 drives the drive shaft 709 to rotate. At the same time, another synchronous belt on the double pulley 605 drives the pulley 606 to rotate, thereby realizing the transmission.

[0042] In this embodiment, as Figure 10 As shown, the feeding mechanism 9 includes a storage box 901 fixedly connected to the middle of the gantry frame 2. A mounting frame 902 is fixedly connected between the inner walls of the storage box 901. A rotating shaft 903 is interference-fitted to the middle of the mounting frame 902 via a bearing. A crushing rod 904 and a spiral blade 905 are integrally formed on the outer surface of the rotating shaft 903. The top end of the rotating shaft 903 extends to the outside of the storage box 901 and connects to the driven gear 906. The driven gear 906 meshes with the residual gear 907. A transmission shaft 9 is fixedly connected to the middle of the bottom surface of the residual gear 907. 08; Driven by the transmission mechanism 6, the transmission shaft 908 rotates, which in turn drives the residual gear 907 at the top to rotate. The residual gear 907 can drive the driven gear 906 to rotate around the rotating shaft 903. The rotating shaft 903 will drive the spiral blade 905 and the crushing rod 904 to rotate. The crushing rod 904 can crush the clumps of powder in the storage box 901, while the rotation of the spiral blade 905 can drive the powder in the storage box 901 to be discharged and finally fall into the tableting groove 501 directly below, realizing the automatic feeding of the tableting groove 501.

[0043] In this embodiment, as Figure 1 and Figure 11As shown, the bottom end of the drive shaft 908 is connected to the pulley 606. The drive shaft 908 rotates through the middle of the gantry frame 2. The outer ring of the residual gear 907 has three-quarters teeth. The bottom of the storage box 901 is provided with a discharge port, and the inner wall of the discharge port is in contact with the spiral blade 905. A feeding channel is opened on one side of the storage box 901. The three-quarters teeth are designed to prevent the spiral blade 905 from starting to rotate and discharge material before the next tableting slot 501 has rotated to the bottom of the storage box 901 during the rotation of the tableting table 5. This would cause the powder to fall on the top surface of the tableting table 5 except for the tableting slot 501. That is, when the tableting table 5 is rotating, the residual gear 907 and the driven gear 906 are not meshed. When the tableting table 5 stops rotating, the residual gear 907 begins to mesh with the driven gear 906, thereby driving the spiral blade 905 to discharge material.

[0044] In this embodiment, as Figure 1 As shown, the top surface of the eccentric wheel 708 is inclined, and the center line of symmetry of the eccentric wheel 708 and the center line of symmetry of the cam 308 form an angle when viewed from above. This structure is to ensure that the cam 308 will contact the trigger ball 305 after the lifting rod 303 pushes the formed dispersed tablet out of the tableting groove 501, and finally drive the arc-shaped push rod 307 to push the dispersed tablet off the tableting table 5. This is because when the top surface of the eccentric wheel 708 rotates to the left, the left side of the reciprocating plate 701 tilts up, and the corresponding left extrusion plate 703 moves up, thereby driving the lifting rod 303 in the feeding assembly 3 to lift the dispersed tablet that has been extruded in the tableting groove 501.

[0045] The working process of this invention is as follows:

[0046] First, the indexing mechanism 4 drives the transmission mechanism 6 and the tableting table 5 to operate. The tableting table 5 rotates indirectly. The transmission mechanism 6 drives the material handling mechanism 3, the tableting mechanism 7, and the feeding mechanism 9 to operate. When the tableting mechanism 7 is running, it drives the cleaning mechanism 8 to clean the tableting mechanism 7. The material handling mechanism 3 can automatically push the tableted dispersion from the tableting table 5 to the unloading slide 506 to achieve automatic material handling. The tableting mechanism 7 mainly extrudes and shapes the powder in the tableting groove 501. The feeding mechanism 9 can automatically add powder to the tableting groove 501.
