Description

Technical Field

[0001] This invention relates to the field of pharmaceutical manufacturing technology, and more specifically, to a rotary tablet press with pressure adaptive adjustment function. Background Technology

[0002] A rotary tablet press is a solid dosage form equipment that uses a rotating turntable and upper and lower punches to continuously complete the filling, tableting and tableting processes. It can compress materials into round, irregularly shaped or tableted tablets with text, and is widely used in the continuous tablet production of pharmaceutical, food and chemical industries.

[0003] When using a tablet press to compress tablets, the raw material must first be injected into the mold; then, the upper and lower dies work together to compress the raw material into tablets. However, during the process of injecting the raw material into the mold, the powder's flowability is poor and its distribution is uneven, resulting in an uneven state of the raw material within the mold cavity. As a result, the tablets produced have significant differences in density uniformity, are prone to breakage during demolding, and affect the uniformity of the release rate during use, ultimately impacting the tablet's efficacy. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a rotary tablet press with pressure adaptive adjustment function to solve the problem of large differences in the density uniformity of the pressed tablets.

[0005] To solve the above problems, the present invention adopts the following technical solution: A rotary tablet press with adaptive pressure adjustment function includes a base, a power assembly installed inside the base, and a pressing auxiliary mechanism disposed on the upper surface of the base. The pressing auxiliary mechanism includes a lower end seat rotatably connected to the upper surface of the base. The power assembly can drive the lower end seat to rotate.

[0006] Furthermore, a vertical plate is fixedly connected to the upper surface of the equipment base, and multiple feeding pipes are fixedly inserted inside the upper end of the vertical plate. The feeding pipes are connected to an external material tank, and an auger is installed inside the feeding pipes for conveying raw materials. The discharge end of the feeding pipes is connected to a discharge hood, and multiple connecting rods are fixedly connected inside the discharge hood. A dispersing platform is fixedly connected to one end of the multiple connecting rods that is close to each other. The dispersing platform is conical in shape.

[0007] Furthermore, a plurality of first hydraulic rods are fixedly connected to the lower surface of the top seat, and a connecting frame is fixedly connected to the lower end of the first hydraulic rods.

[0008] Furthermore, a top post is inserted inside the outer mold, and an inner mold is fixedly connected to the bottom end of the top post. A spring is fixedly connected to the upper surface of the inner mold, and the top end of the spring is fixedly connected to the inside of the outer mold. An abutment post is fixedly connected to the lower surface of the connecting frame.

[0009] Furthermore, a plurality of second hydraulic rods are fixedly connected to the upper surface of the equipment base, and an inner mold is fixedly connected to the top of the second hydraulic rods. The inner mold and the bottom of the forming mold are rotatably inserted into each other. A separation mold block is inserted inside the inner mold, and a guide line is fixedly connected to the surface of the separation mold block. A guide groove adapted to the guide line is opened inside the inner mold. A plurality of suspension plates are fixedly connected to the lower surface of the forming mold. The plurality of suspension plates are arranged in pairs. An electric telescopic rod is rotatably connected to the bottom of the suspension plate, and a push wheel is rotatably connected to the upper end of the electric telescopic rod.

[0010] Furthermore, a distance limiting post is fixedly connected to the lower surface of the separating mold block, and the distance limiting post is inserted into the bottom end of the inner mold.

[0011] Furthermore, the number of the first hydraulic rod and the second hydraulic rod are equal, and their positions correspond one-to-one.

[0012] Furthermore, a bracket is fixedly connected to the upper surface of the equipment base, a discharge channel is fixedly connected to the top of the bracket, a first guide plate is fixedly connected to the upper end of the discharge channel, a second guide plate is fixedly connected to the inside of the discharge channel, and two third guide plates are fixedly connected to the inside of the discharge channel.

[0013] Furthermore, a support block is fixedly connected to the left side of the discharge channel, a support plate is fixedly connected to the right side of the discharge channel, a second motor is fixedly connected to the right side of the discharge channel, and rotating shafts are provided on both sides of the discharge channel. The rotating shaft on the left side of the discharge channel is rotatably connected to the inside of the support block, and the rotating shaft on the right side of the discharge channel is fixedly connected to the output shaft of the second motor.

[0014] Furthermore, a second drive shaft is fixedly connected to the surface of each of the two rotating shafts, and a first drive shaft is rotatably connected to the surface of the second drive shaft. The two first drive shafts and the two second drive shafts are respectively connected by two transmission grinding strips. A passive helical gear and an active helical gear are fixedly connected to the side of the first drive shaft and the second drive shaft that are far away from each other on the right side of the discharge channel. A transmission helical gear is rotatably connected to the lower surface of the support plate. Both the active helical gear and the passive helical gear mesh with the transmission helical gear.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) In this scheme, when the tablet is pressed, the raw material is sprinkled onto the surface of the dispersing table and continues to slide down, so that the raw material is dispersed in the molding die in a ring. Before the tablet is formed, the raw material is evenly distributed in a ring. When the raw material is pressed, it is squeezed and gradually flows towards the inside. The raw material has a shorter flow path during the flow process, which can improve the density uniformity of the pressed tablet, reduce the breakage rate when the tablet is demolded, and improve the quality of the tablet.

[0016] (2) This scheme uses a first motor to drive the molding die to rotate and generate centrifugal force to disperse the raw material inside the molding die to the inner wall of the molding die. This allows the raw material to quickly form a more uniform ring layout after the initial ring distribution. When the raw material is pressed, it is squeezed and gradually flows towards the inside. The raw material has a shorter flow path during the flow process. When the raw material is pressed, the density uniformity of the pressed tablets can be improved, the breakage rate of the tablets during demolding can be reduced, and the quality of the tablets can be further improved.

[0017] (3) After the pressing is completed, this scheme can prevent excessive negative pressure from being generated when the outer mold and the inner mold are released from the surface of the tablet first, which would cause the tablet to break. This further reduces the breakage rate of the tablet during demolding and improves the quality of the tablet.

[0018] (4) In this scheme, after the inner and outer pressure molds are separated from the molding mold, the separation mold block is pushed upward by an electric telescopic rod. The separation mold block can be rotated slightly by the guide line, which can push the tablet upward and rotate the tablet at the same time, thereby achieving pre-separation of the tablet, reducing the probability of edge breakage during the tablet separation process, and improving the quality of the tablet.

[0019] (5) After the tablet is pressed, the tablet moves into the discharge channel and continues to slide downward. At this time, the second motor drives the transmission grinding strip, which can drive the tablet to move downward along the two third guide plates while cleaning the flash and raw material powder on the tablet surface. This prevents the flash from protruding above the tablet surface, which would cause it to be ground off first during coating, exposing the tablet core and causing defects. This improves the quality of the tablet and prevents excessive raw material powder from causing excessive dosage and rapid absorption after administration. Attached Figure Description

[0023] Please see Figures 1-6 A rotary tablet press with adaptive pressure adjustment function includes a base 1, a power assembly installed inside the base 1, and a pressing auxiliary mechanism disposed on the upper surface of the base 1. The pressing auxiliary mechanism includes a lower end seat 201 rotatably connected to the upper surface of the base 1. The power assembly can drive the lower end seat 201 to rotate. A forming seat 204 is fixedly connected to the upper surface of the lower end seat 201. Multiple forming molds 207 are rotatably connected inside the forming seat 204. A top seat 203 is fixedly connected to the upper surface of the middle part of the forming seat 204. A first motor 208 is fixedly connected to the interior of the lower end seat 201. A rotating frame 211 is fixedly connected to the output shaft of the first motor 208. A first external toothed ring 209 is fixedly sleeved on the surface of the rotating frame 211. A second external toothed ring 210 is fixedly sleeved on the outer surface of the forming molds 207. The first external toothed ring 209 meshes with multiple second external toothed rings 210.

[0024] The equipment base 1 has a vertical plate 202 fixedly connected to its upper surface. Multiple feeding pipes 212 are fixedly inserted inside the upper end of the vertical plate 202. The feeding pipes 212 are connected to an external material tank. An auger 219 is installed inside the feeding pipes 212 for conveying raw materials. The discharge end of the feeding pipes 212 is connected to a discharge hood 220. Multiple connecting rods 222 are fixedly connected inside the discharge hood 220. A dispersing platform 221 is fixedly connected to one end of the multiple connecting rods 222 that is close to each other. The dispersing platform 221 is conical in shape.

[0025] The lower surface of the top seat 203 is fixedly connected to a plurality of first hydraulic rods 205. The lower end of the first hydraulic rods 205 is fixedly connected to a connecting frame 213. The bottom ends of the multiple arm ends of the connecting frame 213 are fixedly connected to an outer pressure mold 214. A top column 216 is inserted into the interior of the outer pressure mold 214. The bottom end of the top column 216 is fixedly connected to an inner pressure mold 218. A spring 217 is fixedly connected to the upper surface of the inner pressure mold 218. The top end of the spring 217 is fixedly connected to the interior of the outer pressure mold 214. An abutment column 215 is fixedly connected to the lower surface of the connecting frame 213.

[0026] The upper surface of the equipment base 1 is fixedly connected to multiple second hydraulic rods 206. An inner mold 223 is fixedly connected to the top of each second hydraulic rod 206. The inner mold 223 is rotatably inserted into the bottom end of the forming mold 207. A separation mold block 224 is inserted inside the inner mold 223. A guide line 225 is fixedly connected to the surface of the separation mold block 224. A guide groove matching the guide line 225 is formed inside the inner mold 223. The forming mold 207... Multiple suspension plates 226 are fixedly connected to the lower surface of 7. The multiple suspension plates 226 are in pairs. The bottom end of the suspension plate 226 is rotatably connected to an electric telescopic rod 227. The upper end of the electric telescopic rod 227 is rotatably connected to a push wheel 229. The lower surface of the separation mold block 224 is fixedly connected to a distance limiting post 228. The distance limiting post 228 is inserted into the bottom end of the inner mold 223. The number of the first hydraulic rod 205 and the second hydraulic rod 206 are equal, and their positions correspond one-to-one.

[0027] By adopting the above technical solution, during tablet compression, the raw material in the material tank is conveyed to the feeding pipe 212 by the auger 219, and then sprinkled onto the surface of the dispersing table 221 and continues to slide down, thus dispersing the raw material in a ring-shaped manner in the forming mold 207. Subsequently, the power component drives the lower end seat 201 to rotate, which in turn drives the forming seat 204 to rotate. While the forming seat 204 rotates, the first motor 208 drives the first external gear ring 209 to rotate, which in turn drives the second external gear ring 210 to rotate, thereby driving the forming mold 207 to rotate. During the rotation of the forming mold 207, centrifugal force is generated, which drives the raw material inside the forming mold 207 to disperse towards the inner wall of the forming mold 207, thereby shaping the raw material. To form a more uniform ring-shaped distribution, the first hydraulic rod 205 pushes the outer mold 214 downward into the molding die 207, applying pressure to the material in the molding die 207 to press the raw material into shape. Subsequently, the second hydraulic rod 206 pushes the inner mold 223 upward, which pushes the shaped tablet upward until it leaves the molding die 207. By ensuring a uniform ring-shaped distribution of the raw material before tablet forming, the raw material is squeezed and gradually flows towards the interior during pressing. The raw material has a shorter flow path during the flow process, thus improving the density uniformity of the pressed tablets, reducing the breakage rate during demolding, and improving the quality of the tablets.

[0028] During tablet compression, as the outer mold 214 and inner mold 218 encounter resistance in contact with the raw material, the inner mold 218 enters the interior of the outer mold 214 until the top post 216 abuts against the surface of the abutment post 215. At this point, the lower surface of the inner mold 218 is flush with the lower surface of the outer mold 214. The spring 217 is in a compressed state, thus compressing the raw material. After compression, the outer mold 214 moves upward first, and the inner mold 218 is pushed by the spring 217 to press tightly against the tablet surface. After the outer mold 214 moves upward a certain distance, it can drive the inner mold 218 to move upward, thus causing the inner mold 218 and outer mold 214 to detach from the tablet surface. By having the outer mold 214 detach from the tablet surface first and then the inner mold 218 detach from the tablet surface, excessive negative pressure can be prevented when the outer mold 214 and inner mold 218 detach from the molding die 207 simultaneously, which could cause the tablet to break. This further reduces the breakage rate of the tablet during demolding and improves the quality of the tablet.

[0029] After the inner mold 218 and outer mold 214 separate from the forming mold 207, the push wheel 229 is moved upward by the electric telescopic rod 227, which in turn pushes the separating mold block 224 upward a short distance. During the upward movement of the separating mold block 224, the guide line 225 can guide the separating mold block 224 to rotate slightly, which can push the tablet upward and rotate the tablet at the same time, thereby achieving pre-separation of the tablet, reducing the probability of edge breakage during tablet separation, and improving the quality of the tablet. Then, the inner mold 223 is pushed upward by the second hydraulic rod 206, which can push the tablet to separate from the forming mold 207.

[0030] like Figures 7-10 As shown, a bracket 301 is fixedly connected to the upper surface of the equipment base 1. A discharge channel 302 is fixedly connected to the top of the bracket 301. A first guide plate 303 is fixedly connected to the upper end of the discharge channel 302. A second guide plate 304 is fixedly connected to the inside of the discharge channel 302. Two third guide plates 305 are fixedly connected to the inside of the discharge channel 302. A support block 308 is fixedly connected to the left side of the discharge channel 302. A support plate 313 is fixedly connected to the right side of the discharge channel 302.

[0031] The discharge channel 302 is fixedly connected to a second motor 307 on its right side. Rotary shafts 315 are provided on both sides of the discharge channel 302. The rotating shaft 315 on the left side of the discharge channel 302 is rotatably connected to the inside of the support block 308. The rotating shaft 315 on the right side of the discharge channel 302 is fixedly connected to the output shaft of the second motor 307. A second transmission shaft 314 is fixedly connected to the surface of each of the two rotating shafts 315. A first transmission shaft 309 is rotatably connected to the surface of the second transmission shaft 314. The two first transmission shafts 309 and the two second transmission shafts 314 are respectively connected by two transmission grinding strips 306. A passive helical gear 310 and an active helical gear 312 are fixedly connected to the sides of the first transmission shaft 309 and the second transmission shaft 314 on the right side of the discharge channel 302 that are far from each other. A transmission helical gear 311 is rotatably connected to the lower surface of the support plate 313. Both the active helical gear 312 and the passive helical gear 310 mesh with the transmission helical gear 311.

[0032] By adopting the above technical solution, after the tablet compression is completed, the forming seat 204 carries the tablet and moves it close to the first guide plate 303. It then continues to move, being blocked and guided by the first guide plate 303, sliding into the discharge channel 302. As it continues to slide downwards along the discharge channel 302, the tablet is guided by the second guide plate 304 to slide between the two third guide plates 305. At this time, the second motor 307 drives the active helical gear 312 to rotate, and through the transmission helical gear 311, it continues to drive the... When the movable helical gear 310 rotates, it drives the second drive shaft 314 to rotate clockwise and the first drive shaft 309 to rotate counterclockwise. The particle size of the grinding strip 306 on the second drive shaft 314 is slightly larger than that on the first drive shaft 309. Therefore, while the tablet moves downward along the two third guide plates 305, the flash and adhering raw material powder on the tablet surface are cleaned, preventing the flash from protruding above the tablet surface and being ground off first during coating, thus exposing the tablet core and causing defects, thereby improving the quality of the tablet.

[0033] Instructions for use: First, the raw materials in the hopper are transported to the feed pipe 212 by the auger 219; Subsequently, it is sprinkled onto the surface of the dispersing table 221 and continues to slide down and disperse in the molding die 207; Subsequently, the power component drives the lower end seat 201 to rotate while simultaneously causing the molding seat 204 to rotate; At the same time, the first motor 208 drives the molding die 207 to rotate at high speed; Next, the first hydraulic rod 205 pushes the outer pressure mold 214 downward into the forming mold 207, applying pressure to the material in the forming mold 207 and pressing the raw material into shape; Subsequently, the second hydraulic rod 206 pushes the inner mold 223 upward, thereby pushing the formed tablet upward until it is removed from the forming mold 207; Next, the molding seat 204, carrying the tablet, moves to a position close to the first guide plate 303; Subsequently, it continues to move and is blocked and guided by the first guide plate 303 to slide into the discharge channel 302; Finally, the second motor 307 drives the transmission grinding strip 306 to clean the burrs and adhering raw material powder on the tablet surface.
