Technical Field

[0001] This utility model relates to the field of pharmaceutical granule packaging technology, and in particular to a pharmaceutical granule slow-feed sorting device. Background Technology

[0002] Health supplements are a type of food, sharing the common characteristics of general food, and can regulate the body's functions. Modern health supplements are generally processed in factories using fully automated processes, which are more hygienic and efficient.

[0003] However, in the packaging process of health supplements, quantitative sorting and packaging are generally carried out by machinery and equipment. By controlling the machine, bagged health supplements are quantitatively packaged into boxes according to multiple varieties and fixed dosage ratios, making them convenient to carry after sealing. Since the accuracy of the quantity of each granule in health supplements is crucial, the need for feeding equipment with high accuracy and high reliability is urgent. Therefore, this application proposes a slow-feeding sorting device for pharmaceutical granules to ensure the accuracy of the quantity of granules discharged. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a reliable pharmaceutical granule slow-feeding sorting device.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a pharmaceutical granule slow-release sorting device, including a sorting ring body, a storage ring platform provided on the inner wall of the sorting ring body, a plurality of vertically arranged sorting and feeding channels distributed on the storage ring platform, and a guide cone inclined downward from the middle to the storage ring platform in the sorting ring body, with a slow-release platform provided at the top center of the guide cone.

[0006] As a preferred technical solution, the distance between the bottom end of the guide cone and the inner wall of the sorting ring is greater than or equal to the diameter of the sorting and unloading channel.

[0007] As a preferred technical solution, the outer periphery of the sorting ring is provided with a transmission part, which is connected to a power component for transmission, and the power component drives the sorting ring to reciprocate in both forward and reverse directions.

[0008] As a preferred technical solution, the sorting ring is rotatably mounted, the transmission part is a transmission gear located on the outer periphery of the sorting ring, the power component includes a motor, the output end of the motor is provided with a power gear, and the power gear and the transmission gear are connected by a toothed belt.

[0009] As a preferred technical solution, the transmission part is a transmission pulley located on the outer periphery of the sorting ring, the power component includes a motor, the output end of the motor is provided with a power pulley, and the power pulley and the transmission pulley are connected by a belt.

[0010] As a preferred technical solution, the transmission part is a transmission sprocket located on the outer periphery of the sorting ring, the power component includes a motor, the output end of the motor is provided with a power sprocket, and the power sprocket and the transmission sprocket are connected by a chain.

[0011] As a preferred technical solution, a medicine storage tank is provided above the sorting ring, and the discharge port of the medicine storage tank extends into the sorting ring and is correspondingly located above the slowing platform.

[0012] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: The sorting ring of this utility model is designed with a slowing platform that can slow down the feeding speed of the medicine storage tank and a storage ring platform that can limit the shaking path of the medicine particles. The two work together to ensure that there are only a small number of medicine particles in the storage ring platform, and the medicine particles are relatively loose.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0016] Example 1: like Figure 1 and Figure 2 As shown, a pharmaceutical granule sorting and feeding mechanism includes a mounting frame. A storage tank 100, a sorting and feeding device 200, and a receiving tank 300 are mounted on the mounting frame. The storage tank 100 is positioned above the sorting and feeding device 200 and fixed to the mounting frame. The receiving tank 300 is positioned below the sorting and feeding device 200 and fixed to the mounting frame. The sorting and feeding device 200 is rotatably mounted on the mounting frame and includes a slow-feeding sorting device and a quantitative feeding device. The slow-feeding sorting device is used to slowly feed the pharmaceutical granules from the storage tank 100 and to sort and temporarily store a small number of granules, which is the slow-feeding sorting device of this application. The quantitative feeding device is used to discharge the temporarily stored pharmaceutical granules from the slow-feeding sorting device according to a specified quantity, and finally collect them into a medicine box through the receiving tank 300, completing the precise quantitative feeding of pharmaceutical granules.

[0017] See Figures 3 to 5 A pharmaceutical granule slow-release sorting device includes a sorting ring 201. The inner wall of the sorting ring 201 is provided with a storage ring platform 202. Multiple vertically arranged sorting and feeding channels 203 are distributed on the storage ring platform 202. The sorting ring 201 also has a guide cone 204 that slopes downwards from the center to the storage ring platform 202. A slow-release platform 205 is located at the top center of the guide cone 204. The bottom discharge port of the medicine storage tank 100 extends into the sorting ring 201 and is positioned above the slow-release platform 205. The slow-release platform 205 is used to slow down the feeding speed of the medicine storage tank 100, and the storage ring platform 202 is used to limit the path of the granules. When the granules fall from the bottom discharge port of the storage tank 100 onto the buffer platform 205, because the buffer platform 205 is flat, the granules pile up on it, causing them to press and accumulate against each other. This prevents the granules in the storage tank 100 from continuing to discharge downwards. The buffer platform 205 prevents excessive or rapid discharge from the storage tank 100, thus avoiding internal accumulation that could hinder the smooth discharge of granules. The state of the granules on the buffer platform 205 is described in [reference needed]. Figure 6 .

[0018] See Figure 5 The distance between the bottom end of the guide cone 204 and the inner wall of the sorting ring 201 is greater than or equal to the diameter of the sorting and feeding channel 203. The medicine particles slide down along the guide cone 204 and fall exactly to the ring position corresponding to the sorting and feeding channel 203 on the sorting ring 201, thus limiting the position of the medicine particles and facilitating their accurate entry into the sorting and feeding channel 203.

[0019] See Figures 3 to 5 The sorting ring 201 is rotatably installed. The outer circumference of the sorting ring 201 is mounted on the mounting frame via bearings and bearing seats. The outer circumference of the sorting ring 201 is provided with a transmission part, which is connected to the power component. The power component drives the sorting ring 201 to rotate back and forth at a certain frequency and a certain rotation angle, that is, rotate forward once, rotate backward once, and then rotate forward again, and so on.

[0020] See Figures 2 to 5 The transmission unit is a transmission gear 206 located on the outer periphery of the sorting ring 201. The transmission gear 206 is fixed to the outer periphery of the sorting ring 201. Of course, the transmission gear 206 can be integrally machined on the outer periphery of the sorting ring 201. The power component includes a motor 207. A power gear 208 is fixed to the output end of the motor 207. The power gear 208 and the transmission gear 206 are connected by a toothed belt 209.

[0021] When the drug particles accumulate on the slowing platform 205, as the sorting ring 201 reciprocates in both forward and reverse directions, the drug particles at the upper edge of the slowing platform 205 will roll down in an orderly manner and along the guide cone 204 into the storage ring 202, where a small amount accumulates on the storage ring 202 and the guide cone 204. (See [reference needed] for the state of this small accumulation.) Figure 6 When the sorting ring 201 rotates forward and backward, the medicine particles on the storage ring 202 will move and enter the sorting and feeding channel 203. Here, the storage ring 202 serves as a route to restrict the movement of the medicine particles. When the sorting ring 201 rotates forward and backward, the medicine particles can only move along the storage ring 202.

[0022] Without the buffer platform 205, when a large number of drug particles accumulate in the sorting ring 201, the particles are tightly compressed together. Even if the sorting ring 201 rotates forward and backward, it is difficult for the drug particles to move left and right smoothly into the sorting and feeding channel 203. Furthermore, without the storage ring platform 202, the movement of the drug particles under the forward and reverse rotation of the sorting ring 201 is disordered and chaotic, making it difficult for the drug particles to enter the sorting and feeding channel 203, thus failing to guarantee the accuracy of subsequent drug particle feeding. Due to the coordinated design of the slow-feeding platform 205 and the storage ring platform 202, only a small number of drug particles are present in the storage ring platform 202. The drug particles are relatively loose. Combined with the forward and reverse rotation of the sorting ring 201, the drug particles in the storage ring platform 202 sway along the storage ring platform 202, and can accurately and smoothly enter the sorting and feeding channel 203, which greatly improves the feeding accuracy of the drug particles.

[0023] The inner diameter of the discharge port of the medicine storage tank 100 is approximately 3-4 times the diameter of the medicine particles. The diameter of the slowing platform 205 is 3-5 times the inner diameter of the discharge port of the medicine storage tank 100. The height between the bottom of the discharge port of the medicine storage tank 100 and the surface of the slowing platform 205 is approximately 2-3 times the diameter of the medicine particles. Therefore, the relatively low height between the medicine storage tank 100 and the slowing platform 205 not only slows down the discharge speed but also allows for gradual and orderly automatic continuous discharge in conjunction with the forward and reverse rotation of the sorting ring 201, eliminating the need for valves or other control mechanisms to control the automatic discharge of the medicine storage tank 100.

[0024] See Figure 3 and Figure 4The quantitative feeding device includes multiple movable pusher plates 210 and a discharge execution mechanism. Each movable pusher plate 210 is circumferentially distributed around the periphery of the sorting ring 201. Each movable pusher plate 210 is provided with a granule discharge port 213 corresponding to each sorting and feeding channel 203. The size of the granule discharge port 213 is only enough to hold one granule, ensuring that only one granule is discharged when the movable pusher plate 210 extends or retracts once. The number of movable pusher plates 210 corresponds one-to-one with the number of sorting and feeding channels 203. A movable pusher plate 210 is positioned below each sorting and feeding channel 203, and each movable pusher plate 210 is equipped with a corresponding discharge actuator. The discharge actuator drives the corresponding movable pusher plate 210 to extend and retract along the sorting ring 201. When the movable pusher plate 210 is retracted, the granule outlet 213 is located below the sorting and feeding channel 203; when the movable pusher plate 210 is extended, the granule outlet 213 is located outside the sorting ring 201. Each discharge actuator is independently controlled by a controller and can operate simultaneously or separately, meaning that each movable pusher plate 210 is independently controlled to extend and retract. The number of times and quantities of the discharge actuator's actions depend on the number of granules to be discharged. In this embodiment, there are 12 movable pusher plates 210. When 5 pills need to be dispensed, 5 of the dispensing actuators are controlled to operate simultaneously. When 10 pills need to be dispensed, 10 of the dispensing actuators are controlled to operate simultaneously. When 24 pills need to be dispensed, all 12 dispensing actuators can be controlled to operate simultaneously once, and then the 12 dispensing actuators can be controlled to operate simultaneously again. Of course, the number of movable pusher plates 210 is not limited to 12; it can be 24, 30, or more.

[0025] See Figure 4 The sorting ring 201 is provided with a plurality of radial guide grooves 211 around its periphery, and each of the movable pusher plates 210 slides along the corresponding radial guide groove 211.

[0026] In this embodiment, the discharge actuator is a push-pull electromagnet 212, and the telescopic rod of the push-pull electromagnet 212 is fixedly connected to one end of the movable push plate 210.

[0027] Below the sorting and feeding device 200, there is a corresponding medicine receiving tank 300. The medicine receiving tank 300 is fixed on the mounting frame. The top opening of the medicine receiving tank 300 is located outside the plurality of movable pusher plates 210. Since the plurality of movable pusher plates 210 are arranged circumferentially, when the movable pusher plates 210 are extended, the medicine particles will fall downward into the medicine receiving tank 300. Therefore, the top opening of the medicine receiving tank 300 is located outside the movable pusher plates 210 in the extended state.

[0028] The working principle of this embodiment is as follows: Before discharge, the power component is activated in advance, causing the medicine particles in the medicine storage tank 100 to fall into the slowing platform 205, and then guided by the guide cone 204 to fall onto the storage ring platform 202. As the sorting ring 201 rotates back and forth, the medicine particles gradually enter the sorting and feeding channel 203 in an orderly manner, filling the sorting and feeding channel 203, waiting for the medicine particles to be discharged. When the medicine box moves to the bottom of the discharge port of the medicine receiving tank 300 under the drive of the conveyor line, the controller receives the instruction to control the corresponding number of discharge actuators to operate, and discharge the corresponding number of medicine granules through the movable pusher plate 210. The medicine granules fall into the medicine box through the medicine storage tank 100, and the medicine box enters the next process under the drive of the conveyor.

[0029] Example 2: This embodiment has a basically the same structure as Embodiment 1, the main difference being the different rotation drive method.

[0030] In this embodiment, the transmission part is a transmission pulley fixedly disposed on the outer periphery of the sorting ring 201, and the power component includes a motor 207. The output end of the motor 207 is fixedly provided with a power pulley, and the power pulley and the transmission pulley are connected by a belt.

[0031] Example 3: This embodiment has a basically the same structure as Embodiment 1, the main difference being the different rotation drive method.

[0032] In this embodiment, the transmission part is a transmission sprocket fixedly disposed on the outer periphery of the sorting ring 201, and the power component includes a motor 207. The output end of the motor 207 is fixedly provided with a power sprocket, and the power sprocket and the transmission sprocket are connected by a chain.
