A machine for filling capsules with pellets

Abstract

This invention discloses a capsule filling machine for microparticles, relating to the field of capsule machine technology. The capsule machine includes a feeding device fixedly connected to its top. By incorporating a feeding device, a storage mechanism, a storage bin, a tray connecting plate, and a top feeding mechanism, this invention effectively avoids uneven feeding of microparticles, improving filling efficiency and dosage accuracy. Specifically, the operator pours microparticles into the capsule machine through the feeding port at the top. The microparticles slide down to the top of the sliding plate under gravity, then slide along a V-shaped chute into the storage bin. The bottom of the storage bin is hollowed out, allowing the microparticles to fall into a feed hopper. The feed hopper has a precise capacity, ensuring accurate filling. Once the storage bin is full, a hydraulic push-pull rod is activated, moving the feed hopper to align with the feeding funnel. The microparticles fall from the bottom of the feed hopper into the funnel and then into the capsule machine. When the feed hopper moves, the bottom of the storage bin is blocked, preventing further microparticle falling.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of capsule machines, and particularly relates to a capsule machine for filling micro-pellets. BACKGROUND

[0002] Micro-pellets are spherical or spherical-like solid dosage forms with small diameters, which can be filled into capsules, compressed into tablets, or made into other preparations. Micro-pellets are a kind of multi-unit oral dosage forms, and the amount of a single dose is composed of dozens to hundreds of small pellets. Different types of micro-pellets, such as sustained-release, enteric-release, and the like, can be prepared. Compared with granules or powders, micro-pellets have better flowability, and do not require flow aids when filling capsules. Compared with powder filling, the weight difference is small, and micro-pellets are often used to prepare compound preparations.

[0003] According to the capsule machine powder filling device disclosed in patent document CN202020396038.6, the device includes a capsule machine rack, a filling mechanism, a double-shaft power mechanism, a servo motor, and a pneumatic cylinder. The double-shaft structure is driven by the servo motor and the pneumatic cylinder to perform powder filling and storage hopper movement, and a tightening screw is provided to adjust the rotation angle.

[0004] In the current market, the setting of the metering assembly plays a crucial role in the widely used capsule machine micro-pellet filling assembly. However, many capsule machines for filling micro-pellets often encounter some difficult problems during actual operation, especially in the micro-pellet feeding process. These problems mainly include blockage during micro-pellet feeding and uneven feeding. These phenomena not only greatly reduce the filling efficiency of the capsule machine, but also seriously affect the accuracy of the filling dose. In addition, due to the relatively small size of the micro-pellets, traditional mechanical structures often cause damage to the micro-pellets during operation. This damage not only destroys the integrity of the micro-pellets, but also may have a negative impact on their drug efficacy. Therefore, how to improve the existing capsule machine micro-pellet filling assembly to solve these problems, improve the filling efficiency and dose accuracy, and protect the integrity and drug efficacy of the micro-pellets has become an important issue that needs to be addressed in the industry.

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

[0018] 1. This application, by incorporating a feeding device, a storage mechanism, a storage bin, a pallet connecting plate, and a top feeding mechanism, effectively avoids the problem of uneven feeding of microcapsules, improving filling efficiency and dosage accuracy. Specifically, the operator pours microcapsules into the inlet at the top of the capsule machine. The microcapsules slide down to the top of the sliding plate under gravity, and then slide along the V-shaped chute into the storage bin. The bottom of the storage bin is hollowed out, allowing the microcapsules to fall into the feed hopper. The feed hopper has a precise capacity, ensuring accurate filling. After the storage bin is full, the hydraulic push-pull rod is activated, causing the feed hopper to move and align with the feeding funnel. The microcapsules fall from the bottom of the feed hopper into the funnel and then into the capsule machine. When the feed hopper moves, the bottom of the storage bin is blocked, preventing the microcapsules from falling further. At the same time, the inclined plate moves to the left with the feed hopper, pushing the inclined plate and push-pull rod upward to seal the top of the feeding bin, preventing debris from falling in and ensuring a clean and smooth filling process.

[0019] 2. This application effectively improves the conveying efficiency of micro pellets by setting up a storage bin, a dual-shaft motor, and an inner storage bin. Specifically, the micro pellets fall into the inner wall of the storage bin under the action of the sliding plate. During discharge, the dual-shaft motor starts and drives two sets of turntables to rotate. The rotating rod rotates accordingly, causing the elliptical sliding block to slide along the rotating rod, pushing the connecting plate to move up and down. The movement of the connecting plate drives the inner storage bin to move up and down, realizing the discharge of micro pellets and avoiding blockage. The hollow design at the top and bottom of the inner storage bin allows the micro pellets to fall into the bottom of the storage bin under the action of gravity, completing the discharge.

The bottom end of the feeding hopper 226 extends to the inner wall of the capsule machine 1. A hydraulic push-pull rod placement plate 214 is fixedly connected to the bottom right side of the upright plate 212. A hydraulic push-pull rod 215 is fixedly connected to the top of the hydraulic push-pull rod placement plate 214. The feeding mechanism 24 includes a feeding barrel connecting plate 241. The outer wall of the feeding barrel connecting plate 241 is slidably connected to the right side of the inner wall of the U-shaped frame 216. The left side of the feeding barrel connecting plate 241 is fixedly connected to the right end of the hydraulic push-pull rod 215. Slider 245s are fixedly connected to the left sides of the front and rear sides of the feeding barrel connecting plate 241, respectively. The outer walls of both sliders 245s are slidably connected to the inner wall of the slide groove 217. The top of the feeding barrel connecting plate 241 is fixedly connected to the inner wall of the slide groove 217. An L-shaped connecting rod 242 is connected to the top of which is a sloping plate 243. A material passage 244 is fixedly connected to the left side of the inner wall of the material passage 241 connecting plate. The top and bottom of the material passage 244 are hollowed out. The bottom of the material passage 244 is slidably connected to the top of the support plate 224. The top feeding mechanism 23 includes a feeding bin 231. The top right side and bottom of the feeding bin 231 are hollowed out. A top feeding port 232 is fixedly connected to the top right side of the feeding bin 231. The top of the top feeding port 232 is hollowed out. A sliding plate 233 is rotatably connected to the right side of the inner wall of the feeding bin 231. A V-shaped groove 234 is opened on the top of the sliding plate 233. A push-pull rod 235 is rotatably connected to the bottom of the sliding plate 233.The bottom of the push-pull rod 235 is fixedly connected to an inclined plate 236. The bottom of the feed hopper 231 is fixedly connected to the top of the vertical plate 212. The bottom of the push-pull rod 235 extends to the bottom of the fixed plate 220 through a slot 221 opened at the top of the fixed plate 220. The bottom of the inclined plate 236 is slidably connected to the top of the inverted inclined plate 243.

[0034] When filling the microcapsules, the operator first pours the microcapsules into the capsule machine through the top feed port 232. Under the action of gravity, the microcapsules slide down along the top feed port 232 to the top of the sliding plate 233 located below. The sliding plate 233 is designed with a 45-degree tilt angle, so that the microcapsules can smoothly slide down along its V-shaped groove 234 into the inside of the storage tank 222. The bottom of the storage tank 222 is designed with a hollow structure, so that the microcapsules can fall smoothly from the bottom of the storage tank 222 into the inside of the feeding tank 244. The capacity of the feeding tank 244 is precisely designed to be the amount of microcapsules required for one filling, ensuring the accuracy of each filling.

[0035] When the micro-pellets inside the storage hopper 222 reach a certain amount, i.e., when it is full, the operator can activate the hydraulic push-pull rod 215. After the hydraulic push-pull rod 215 is activated, it will pull the feeding hopper connecting plate 241 to move to the left. The movement of the feeding hopper connecting plate 241 will cause the feeding hopper 244 to move to the left, so that its top is aligned with the top of the feeding funnel 226. During the process of the feeding hopper 244 moving to the left, its bottom end is no longer closed by the support plate 224, and the micro-pellets can fall smoothly from the bottom of the feeding hopper 244 into the inner wall of the feeding funnel 226. Subsequently, the micro-pellets fall into the capsule machine 1 through the feeding funnel 226.

[0036] As the connecting plate 241 of the feeding hopper moves to the left, the top right side of the connecting plate will block the bottom of the storage hopper 222, thus preventing the micro-particles from continuing to fall from the bottom of the storage hopper 222. At the same time, when the connecting plate 241 of the feeding hopper moves to the left, the inclined plate 243 will also move to the left along with it. The inclined surface of the inclined plate 243 is opposite to that of the inclined plate 236. Therefore, when the inclined plate 243 moves to the left, it will slide at the bottom of the inclined plate 236 and push the inclined plate 236 and the push-pull rod 235 upward when it moves to the leftmost position. The upward movement of the push-pull rod 235 will drive the sliding plate 233 to rotate, making it parallel to the top of the feed hopper 231, thereby sealing the top of the feed hopper 231. This action effectively prevents other debris from falling into the storage hopper 222 through the top feed port 232, ensuring the cleanliness and smoothness of the filling process.

[0037] Please see Figures 8-10The storage bin 222 includes a storage bin body 2221. A bottom tray 2224 is fixedly connected to the bottom of the inner wall of the storage bin body 2221. C-shaped connecting plates 2223 are fixedly connected to the top two sides of the bottom tray 2224. Dual-axis motors 2226 are fixedly connected to the inner walls of the two C-shaped connecting plates 2223. Turntables 2227 are fixedly connected to the front and rear ends of the two dual-axis motors 2226. Rotating rods 2228 are fixedly connected to the side of the two turntables 2227 away from the dual-axis motors 2226. Elliptical sliding blocks 2229 are slidably connected to the outer walls of the two rotating rods 2228. The inner walls of the two elliptical sliding blocks 2229 are slidably connected to the outer walls of the rotating rods 2228. The tops of the two elliptical sliding blocks 2229 are fixedly connected to the outer walls of the rotating rods 2228. Two sets of round rods 2230 are fixedly connected. The top ends of the two sets of round rods 2230 extend to the top of the C-shaped connecting plate 2223 and the bottom of the outer wall of the two sets of push-pull rod connecting plates 2231 are fixedly connected. The bottom ends of the two sets of push-pull rod connecting plates 2231 are fixedly connected to springs 2232. The outer walls of the two sets of springs 2232 are sleeved on the outer walls of the two sets of round rods 2230. The top ends of the two sets of round rods 2230 are fixedly connected to connecting plates 2225. The top ends of the two sets of round rods 2230 are respectively fixedly connected to the two sides of the bottom of the connecting plates 2225. The outer wall of the connecting plates 2225 is slidably connected to the inner wall of the storage barrel body 2221. The inner wall of the connecting plates 2225 is fixedly connected to the inner barrel 2222. The top and bottom of the inner barrel 2222 are hollowed out.

[0038] During the production process, the micro-pellets smoothly fall into the inner wall of the storage inner barrel 2222 within the main body 2221 of the storage barrel through the action of the sliding plate 233. When a feeding operation is required, the dual-axis motors 2226 on the inner walls of the two C-shaped connecting plates 2223 will start. After the dual-axis motors 2226 start, they will simultaneously drive the two sets of turntables 2227 to rotate. The rotation of the turntables 2227 drives the rotating rod 2228 to rotate, which in turn causes the elliptical sliding block 2229 to slide along the outer wall of the rotating rod 2228. As the elliptical sliding block 2229 rotates, the round rod 2230 will move up and down, pushing and pulling the connecting plate 2225. Under the sliding action of the inner wall of the storage tank body 2221, 225 begins to move up and down along the inner wall. The up and down movement of the connecting plate 2225 drives the storage inner tank 2222 to move up and down, thereby realizing the discharge of micro pellets. This process effectively prevents micro pellets from being blocked on the inner wall of the storage inner tank 2222 due to static electricity or other reasons. Since the top and bottom of the storage inner tank 2222 are hollowed out, the micro pellets will fall from the bottom of the storage inner tank 2222 into the bottom of the storage tank body 2221 under the action of gravity. In this way, the micro pellets can be discharged through the bottom of the storage tank body 2221, ensuring the smoothness and efficiency of the entire production process.

[0039] Working principle: During the filling of microcapsules, the operator first pours the microcapsules into the capsule machine through the top inlet 232. Under the action of gravity, the microcapsules slide down along the top inlet 232 to the top of the sliding plate 233 located below. The sliding plate 233 is designed with a 45-degree inclination angle, allowing the microcapsules to smoothly slide down its V-shaped groove 234 into the storage tank 222. The bottom of the storage tank 222 is designed with a hollow structure, so that the microcapsules can fall smoothly from the bottom of the storage tank 222. Inside the feeding hopper 244, the capacity is precisely designed to meet the amount of micro-pellets required for a single feeding, ensuring accuracy in each filling. When the micro-pellets inside the storage hopper 222 reach a certain amount, i.e., when it is full, the operator can activate the hydraulic push-pull rod 215. Activation of the hydraulic push-pull rod 215 pulls the feeding hopper connecting plate 241 to the left. This movement of the connecting plate 241 causes the feeding hopper 244 to move to the left, aligning its top with the top of the feeding funnel 226. During this leftward movement... In this process, the bottom end is no longer sealed by the support plate 224, allowing the micro-pellets to fall smoothly from the bottom of the feeding hopper 244 into the inner wall of the feeding funnel 226. Subsequently, the micro-pellets fall into the capsule machine 1 through the feeding funnel 226. As the feeding hopper connecting plate 241 moves to the left, the top right side of the connecting plate blocks the bottom of the storage hopper 222, preventing the micro-pellets from continuing to fall from the bottom of the storage hopper 222. At the same time, as the feeding hopper connecting plate 241 moves to the left, the tilting plate 243 also moves to the left along with it. The inclined surfaces of plate 243 and inclined plate 236 are opposite in direction. Therefore, when the inclined plate 243 moves to the left, it slides at the bottom of the inclined plate 236 and pushes the inclined plate 236 and the push-pull rod 235 upward when it moves to the leftmost side. The upward movement of the push-pull rod 235 drives the sliding plate 233 to rotate, making it parallel to the top of the feed bin 231, thereby sealing the top of the feed bin 231. This action effectively prevents other debris from falling into the storage bin 222 through the top feed port 232, ensuring a clean and smooth filling process.

[0040] During the production process, the micro-pellets smoothly fall into the inner wall of the storage inner barrel 2222 within the main body 2221 of the storage barrel through the action of the sliding plate 233. When a feeding operation is required, the dual-axis motors 2226 on the inner walls of the two C-shaped connecting plates 2223 will start. After the dual-axis motors 2226 start, they will simultaneously drive the two sets of turntables 2227 to rotate. The rotation of the turntables 2227 drives the rotating rod 2228 to rotate, which in turn causes the elliptical sliding block 2229 to slide along the outer wall of the rotating rod 2228. As the elliptical sliding block 2229 rotates, the round rod 2230 will move up and down, pushing and pulling the connecting plate 2225. Under the sliding action of the inner wall of the storage tank body 2221, 225 begins to move up and down along the inner wall. The up and down movement of the connecting plate 2225 drives the storage inner tank 2222 to move up and down, thereby realizing the discharge of micro pellets. This process effectively prevents micro pellets from being blocked on the inner wall of the storage inner tank 2222 due to static electricity or other reasons. Since the top and bottom of the storage inner tank 2222 are hollowed out, the micro pellets will fall from the bottom of the storage inner tank 2222 into the bottom of the storage tank body 2221 under the action of gravity. In this way, the micro pellets can be discharged through the bottom of the storage tank body 2221, ensuring the smoothness and efficiency of the entire production process.
