Description

Technical Field

[0001] This utility model relates to the field of tablet manufacturing technology, specifically a tablet polishing machine for tablet manufacturing. Background Technology

[0002] In the pharmaceutical manufacturing industry, tablets, as a common dosage form, have stringent requirements for their appearance quality. The surface smoothness of tablets not only affects the aesthetics of the drug but is also closely related to its stability, shelf life, and patient experience. Therefore, tablet polishing has become an indispensable and crucial step in the pharmaceutical manufacturing process.

[0003] Chinese Patent (Authorization Announcement No.: CN 216883286 U, Authorization Announcement Date: 2022.07.05 CN216883286 U) discloses a polishing device for tablet drug processing, including a fixed base. Two sets of drive motors are mounted on the upper end of the fixed base. A polishing box is fixed to the upper end of the fixed base via a column. Two sets of first sealed bearings are embedded in the inner wall of the bottom of the polishing box. A first transmission rod is fixedly inserted into the inner ring of each of the two sets of first sealed bearings. A polishing plate is mounted on one end of the first transmission rod, and the other end of the first transmission rod is connected to the output end of the electric motor. Two sets of second sealed bearings are embedded in the inner wall of the upper end of the polishing box. A second transmission rod is fixedly inserted into the inner ring of each of the two sets of second sealed bearings. One end of the second transmission rod is mounted on the upper end of the polishing plate. This invention, by setting two sets of drive motors, allows for secondary polishing of the drug during polishing in the polishing machine, resulting in a higher surface smoothness. The polishing cotton attached to the polishing plate can be frequently replaced, and the operation is simple.

[0004] When the above-mentioned polishing device polishes tablets, the tablets are placed statically inside the polishing box, resulting in incomplete contact between the polishing mechanism and the tablets, which leads to poor polishing effect. In addition, dust is generated on the surface of the tablets during polishing, and the above-mentioned polishing device does not have a dust collection mechanism, which reduces the practicality of the polishing device. Therefore, we propose a tablet polishing machine for pharmaceutical production. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 This utility model provides a technical solution: a tablet polishing machine for pharmaceutical tablet production, including a polishing machine body 1, a feed hopper 2 on the left side of the polishing machine body 1, a discharge port 16 on the rear side of the polishing machine body 1, a rotating plate 8 rotatably mounted on the inner wall of the polishing machine body 1, a sieve plate 7 on the top of the rotating plate 8, a vibration component mounted on the inner wall of the polishing machine body 1, a polishing component mounted on the top of the polishing machine body 1, a rotating component mounted on the right side of the polishing machine body 1, and a dust collection component mounted on the bottom inside the polishing machine body 1.

[0018] This tablet polishing machine for tablet production feeds tablets through the feed hopper 2. After entering the polishing machine body 1, the tablets fall onto the surface of the sieve plate 7. The sieve plate 7 is then rotated by a rotating component, and the tablets on the surface of the sieve plate 7 are polished by a polishing component installed on the top of the polishing machine body 1. During the rotation of the sieve plate 7, the vibrating component installed on the inner wall of the polishing machine body 1 continuously vibrates the sieve plate 7, causing the tablets to flip over during the vibration, thus making the polishing of the tablets more thorough. During the vibration of the sieve plate 7, dust on the surface of the tablets falls from the filter holes of the sieve plate 7 and is collected by a dust collection component installed on the bottom inside the polishing machine body 1 to prevent the dust from escaping into the air. After polishing, the tablets are discharged through the discharge port 16.

[0019] The vibration assembly includes a mounting plate 17, which is fixedly connected to the inner wall of the polishing machine body 1. A fixing block 24 is fixedly connected to the top side of the middle part of the mounting plate 17. A slot 25 is opened on the top of the fixing block 24. Several semi-circular grooves 26 are opened on the bottom side of the slot 25. A connecting pipe 27 is fixedly connected to the bottom side of the middle part of the sieve plate 7. A pressure plate 28 is fixedly connected to the bottom end of the connecting pipe 27. Several hemispheres 29 are fixedly connected to the bottom side of the pressure plate 28. The bottom side of the hemispheres 29 abuts against the inner surface of the semi-circular grooves 26. A reset mechanism is installed between the sieve plate 7 and the rotating plate 8.

[0020] The reset mechanism includes a lifting plate 33, which is fixedly connected to the bottom side of the screen plate 7. Several fixing rods 30 are installed on the lifting plate 33. Two sets of connecting plates 31 are fixedly connected to the inner wall of the rotating plate 8. The top and bottom ends of the fixing rods 30 are fixedly connected to the two sets of connecting plates 31 respectively. Springs 32 are sleeved on the upper and lower sides of the fixing rods 30. The two ends of the springs 32 abut against the connecting plates 31 and the lifting plate 33 respectively.

[0021] When the vibration assembly is in use, the screen plate 7 rotates, which in turn drives the pressure plate 28 to rotate through the connecting pipe 27. Since the pressure plate 28 abuts against the slot 25 opened on the top of the fixed block 24, and the fixed block 24 is fixedly connected to the inner wall of the polishing machine body 1 through the mounting plate 17, the fixed block 24 does not move during the rotation of the pressure plate 28. Since the hemispheres 29 fixedly connected to the bottom side of the pressure plate 28 are fitted into the hemispheres 26 opened on the bottom side of the slot 25, and the lifting plate 33 fixedly connected to the bottom of the screen plate 7 is placed between the two sets of connecting plates 31 fixedly connected to the inner wall of the rotating plate 8, and the lifting plate 33 is slidably sleeved on the several fixed rods 30 fixedly connected between the two sets of connecting plates 31, the screen plate 7 vibrates and rises and falls as the hemispheres 29 and the hemispheres 29 and the hemispheres 26 continuously disengage and engage. In order to make the screen plate 7 quickly return to its original position during vibration, springs 32 are sleeved on both the upper and lower sides of the fixed rods 30, and the two sets of springs 32 respectively buffer and return the upper and lower sides of the screen plate 7.

[0022] The polishing assembly includes a drive motor 3, which is fixedly mounted on the top of the polishing machine body 1. A fixed tube 5 is fixedly connected to the bottom of the top of the polishing machine body 1. A rotating rod 18 passes through the inside of the fixed tube 5. The top end of the rotating rod 18 is fixedly connected to the output shaft end of the drive motor 3. A fixed box 21 is fixedly connected to the bottom of the fixed tube 5. The rotating rod 18 rotates and extends into the inside of the fixed box 21. A bevel gear 19 is fixedly connected to the bottom end of the rotating rod 18. Polishing rollers 22 are rotatably passed through the left and right sides of the fixed box 21. A bevel gear 20 is fixedly connected to the end of each of the two sets of polishing rollers 22 that are close to each other. Both sets of bevel gears 20 mesh with bevel gear 19. Several brush heads 23 are fixedly connected to the outer surface of the polishing rollers 22.

[0023] When the polishing assembly is in use, the drive motor 3 rotates the rotating rod 18, which in turn rotates the bevel gear 19 at the bottom, and then rotates the two sets of bevel gears 20 that mesh with it, so that the two sets of polishing rollers 22 rotate synchronously, and the tablet medicine is polished by a number of brush heads 23 fixedly connected to the surface of the polishing rollers 22.

[0024] The rotating assembly includes a second drive motor 6, which is fixedly installed on the right side of the polishing machine body 1. A gear 10 is fixedly connected to the output shaft end of the second drive motor 6. A gear ring 9 is fixedly sleeved on the outer surface of the rotating plate 8, and the gear ring 9 meshes with the gear 10.

[0025] When the rotating assembly is in use, the drive motor 6 rotates the gear 10, thereby rotating the meshing gear ring 9, and driving the rotating plate 8 to rotate on the inner wall of the polishing machine body 1.

[0026] The dust collection assembly includes a funnel 14, which is fixedly connected to the inner wall of the polishing machine body 1. An air outlet 15 is provided at the bottom end of the funnel 14, and an air outlet pipe 11 is fixedly connected to the bottom end of the air outlet 15. A fan 12 and a dust collection bag 13 are fixedly installed on the inner bottom side of the polishing machine body 1. The output end of the air outlet pipe 11 is fixedly connected to the input end of the fan 12, and the output end of the fan 12 is fixedly connected to the input end of the dust collection bag 13 through a pipe.

[0027] When the dust collection assembly is in use, the dust falling on the sieve plate 7 falls into the funnel 14. When the fan 12 is started, the dust in the funnel 14 enters the air outlet 11 through the air outlet 15, and is then transported to the dust collection bag 13 for collection.

[0028] The front side of the polishing machine body 1 is provided with an inspection door 4, which facilitates the maintenance of the internal equipment.

[0029] Working principle: This tablet polishing machine for tablet production feeds tablets into the machine body 1 via the feed hopper 2. The tablets fall onto the surface of the sieve plate 7 after entering the machine body 1. The drive motor 6 rotates the gear 10, which in turn rotates the gear ring 9 that meshes with it, causing the rotating plate 8 to rotate on the inner wall of the machine body 1. Since the sieve plate 7 is slidably mounted on the rotating plate 8 via several fixed rods 30, the sieve plate 7 rotates. Then, the drive motor 3 rotates the rotating rod 18, which in turn rotates the bevel gear 19 at the bottom, which in turn rotates the two sets of bevel gears 20 that mesh with it, causing the two sets of polishing rollers 22 to rotate synchronously. Several brush heads 23 fixedly connected to the surface of the polishing rollers 22 polish the tablets on the surface of the sieve plate 7. During the rotation of the sieve plate 7, the pressure plate 28 is driven to rotate via the connecting pipe 27. Since the pressure plate 28 abuts against the slot 25 opened on the top of the fixing block 24, and the fixing block 24 is fixedly connected to the inner wall of the polishing machine body 1 via the mounting plate 17, the fixing block 24 does not move during the rotation of the pressure plate 28. Because the several hemispherical balls 29 fixedly connected to the bottom side of the pressure plate 28 are fitted into the several hemispherical grooves 26 opened on the bottom side of the slot 25, and the lifting plate 33 fixedly connected to the bottom of the sieve plate 7 is placed on the inner wall of the rotating plate 8 and fixedly connected... Between the two sets of connecting plates 31, and with the lifting plate 33 slidably sleeved on several fixed rods 30 fixedly connected between the two sets of connecting plates 31, as the hemisphere 29 and the hemisphere groove 26 continuously disengage and engage, the sieve plate 7 vibrates and rises, causing the tablets to continuously flip during vibration, thus making the polishing of the tablets more thorough. In order to make the sieve plate 7 quickly return to its original position during vibration, springs 32 are sleeved on both the upper and lower sides of the fixed rods 30, and the two sets of springs 32 respectively buffer and return the upper and lower sides of the sieve plate 7. During the vibration of the sieve plate 7, the dust on the surface of the tablet falls through the filter holes of the sieve plate 7 and into the funnel 14. Then, the blower 12 is started, and the dust in the funnel 14 enters the air outlet 11 through the air outlet 15, thereby being transported to the dust collection bag 13 to collect the dust and prevent it from escaping into the air. After polishing, the tablet is discharged through the discharge port 16.
