Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically to a granule dispensing device. Background Technology

[0002] During the drug packaging process, the dosage of each bag is strictly controlled. If the dosage of the packaged drug is unstable, the patient will not be able to accurately calculate the dosage when taking it, which may cause serious medical accidents. In the current granule drug packaging method, a feeding hopper is installed above the rotating upper plate. The lower end of the feeding hopper is fitted with the upper end of the material tray with a gap because the measuring cup interface is constantly rotating while the hopper is stationary, and a gap needs to be left between the two. When the discharge hole on the upper plate rotates to the lower end of the feed hopper, material is discharged. The upper plate rotates to continuously distribute the material. With the current structure, the thickness of the material pile in the feed hopper gradually decreases as the material is distributed. The existing feed hopper is relatively thick, and the material pile is relatively thick. During the distribution process, the material pressure is significant in the early and late stages of distribution. When entering the measuring cylinder, the pressure state of the particles inside the measuring cylinder varies greatly, and the significant difference in compaction density leads to large error fluctuations in the dosage in the measuring cup, causing the actual amount of medicine to increase or decrease significantly, resulting in a significant decrease in the product qualification rate. At the same time, with the current material distribution method, the hopper is relatively deep, making it difficult to observe. In addition, during the material blockage process, it is impossible to clean the material at the bottom of the deep feed hopper, causing it to continue to leak. The discharge hole cannot be filled with a sufficient amount of granular material in a timely manner. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a granule dispensing device. This device enables accurate dispensing of granular drugs or powders, significantly improving product qualification rates, reducing production costs, minimizing material buildup in the feed hopper, facilitating monitoring of the feeding process, and enabling rapid clearing and resumption of production in case of blockages, thereby significantly improving production efficiency.

[0004] The purpose of this utility model is achieved as follows:

[0005] A granule fabrication device includes a frame, a rotating shaft mounted on the frame, and upper and lower plates fixed at intervals along the shaft's extension direction.

[0006] The upper plate is provided with a plurality of annular arrays of upper discharge holes, and the lower plate is provided with corresponding lower discharge holes. The upper discharge holes and the corresponding lower discharge holes are connected by a measuring cylinder.

[0007] The bottom of the lower plate is equipped with an openable and closable cover plate corresponding to each discharge hole, and a receiving hopper is provided below the lower plate.

[0008] It also includes a feeding mechanism, which comprises a belt conveyor. A feeding frame is mounted on the frame of the belt conveyor, and a hopper is provided inside the feeding frame. A feed inlet is located at the upper end of the hopper.

[0009] The hopper is located above the conveyor belt of the belt conveyor. Sealing strips are provided on the lower sides of the two side walls of the hopper, and the sealing strips are sealed with the conveyor belt. The front wall of the hopper is provided with a discharge port. A feed hopper for receiving material from the belt conveyor is provided above the upper plate. The discharge port of the feed hopper corresponds to the movement trajectory above the upper leakage hole.

[0010] The feeding frame is connected to the frame of the belt conveyor and is gap-fitted with the conveyor belt of the belt conveyor. The feeding frame is connected and fixed with a left side plate, a right side plate, a front plate and a rear plate. The left side plate, the right side plate, the front plate and the rear plate form a hopper. A gap is left between the left side plate and the right side plate and the conveyor belt. A sealing strip brush is installed in the gap. The sealing strip brush is connected to the lower part of the corresponding side plate. A gap is left between the front plate and the conveyor belt. A pair of sealing strip brushes is installed in the gap. A discharge port is left in the middle of the pair of sealing strip brushes.

[0011] The downstream end of the belt conveyor is provided with a receiving trough, and the downstream end of the receiving trough is located above the feed hopper.

[0012] The lower side of the front wall of the hopper is provided with a first sealing strip brush and a second sealing strip brush, and a discharge port is provided between the first sealing strip brush and the second sealing strip brush.

[0013] The front wall is V-shaped, and the discharge port is located at the outermost end of the front wall.

[0014] The distance between the upper and lower plates is adjustable. The measuring cylinder includes a lower cylinder and an upper cylinder. The upper end of the upper cylinder is connected to the upper discharge hole, and the lower end of the lower cylinder is connected to the lower discharge hole. The lower end of the upper cylinder is inserted into the upper end of the lower cylinder.

[0015] The cover plate is connected to the lower plate via a rotatable pin. The edge of the cover plate facing the rotation direction of the upper plate is provided with a first mating surface. The end face of the cover plate is provided with a downward protruding rib. The side of the protruding rib facing the rotation direction of the upper plate is provided with a second mating surface. The first mating surface and the second mating surface are arranged radially offset. A first lever and a second lever are provided on the frame. The upward extension end of the first lever can interfere with the first mating surface in the direction of movement. The upward extension end of the second lever can interfere with the second mating surface in the direction of movement. The distances from the head end of the first lever and the head end of the second lever to the center line of the main shaft are not equal.

[0016] The above scheme offers the following advantages: The rotation of the shaft drives the upper and lower plates, as well as the measuring cylinder, to rotate as a whole. When the upper discharge hole on the upper plate is below the feed hopper, the measuring cylinder below the feed hopper's outlet begins to fill. When the measuring cylinder moves above the receiving hopper, the cover plate opens, and the measuring cylinder begins to discharge. The particles are accurately measured and enter the receiving hopper. After discharge, the cover plate closes. The material accumulation in the feed hopper is relatively thin, and the compaction is relatively small in the vertical filling state, allowing each measuring cylinder to distribute material relatively evenly. This is especially beneficial in the early and late stages of batch material distribution, where the error in measuring cylinder distribution is smaller. The belt conveyor can continuously feed material into the feed hopper, and a single addition to the hopper allows for continuous material distribution over a longer period. This utility model has a simple structure and can accurately dispense granular drugs or powders, significantly improving product qualification rate and reducing production costs. The feed hopper has less material retention, facilitating observation of the feed and enabling quick clearing and resumption of production in case of blockage, thus significantly improving production efficiency. The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this utility model. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] See Figures 1-3 An embodiment of a granule dispensing device includes a frame 100, on which a rotating shaft 101 is mounted. An upper plate 102 and a lower plate 103 are fixed at intervals along the shaft 101's extension direction. The upper plate 102 has a plurality of annular arrayed upper discharge holes, and the lower plate 103 has corresponding lower discharge holes. The upper discharge holes and their corresponding lower discharge holes are connected by a measuring cylinder 104.

[0026] The bottom of the lower plate 103 is provided with an openable and closable cover plate 400 corresponding to each lower discharge hole opening, and a receiving hopper 105 is provided below the lower plate 103.

[0027] It also includes a feeding mechanism 200, which includes a belt conveyor 210. A feeding frame 220 is provided on the frame of the belt conveyor 210. A hopper 221 is provided inside the feeding frame 220. A feed inlet 222 is provided at the upper end of the hopper 221. The hopper 221 is located above the conveyor belt 2211 of the belt conveyor 210. Sealing strips are provided on the lower part of the side walls of the hopper 221. The sealing strips seal with the conveyor belt 2211 without obstructing the movement of the conveyor belt. A discharge outlet 2212 is provided on the front wall of the hopper 221. A feed hopper 300 for receiving material from the belt conveyor 210 is provided above the upper plate 102. The discharge outlet 2212 of the feed hopper 300 corresponds to the movement trajectory above the upper leakage hole.

[0028] In some embodiments, the feeding frame 220 is connected to the frame of the belt conveyor 210, and the feeding frame 220 serves as a support and is in clearance fit with the conveyor belt 2211 of the belt conveyor 210. The feeding frame 220 is internally connected and fixed with a left side plate, a right side plate, a front plate, and a rear plate 2214. The left side plate 2213, the right side plate 2218, the front plate 2217, and the rear plate 2214 form a hopper 221, which forms a storage space. A gap 2215 is left between the left side plate, the right side plate, and the conveyor belt 2211. A sealing strip brush is provided in the gap 2215. The sealing strip brush is connected to the lower edge of the corresponding side plate. A gap 2215 is left between the front plate 2217 and the conveyor belt 2211. A pair of sealing strip brushes are provided in the gap 2215. A discharge port 2212 is left in the middle of the pair of sealing strip brushes.

[0029] In some embodiments, a receiving trough 230 is provided at the downstream end of the belt conveyor 210. The downstream end of the receiving trough 230 is located above the feed hopper. The receiving trough can transfer materials from the conveyor belt to the feed hopper, allowing for flexible arrangement of the belt conveyor.

[0030] In some embodiments, a first sealing strip brush and a second sealing strip brush are provided on the lower side of the front wall of the hopper 221, and a discharge port is provided between the first sealing strip brush and the second sealing strip brush to restrict the discharge of the hopper 221 to the central area of ​​the conveyor belt, forming a narrower material belt, which facilitates the entry into the feed hopper. The feed hopper can be of a smaller size, while preventing the material from spilling at the edge of the conveyor belt.

[0031] In some embodiments, the front wall is V-shaped, and the discharge port 2212 is located at the outermost end of the front wall. The V-shaped structure serves to collect materials, so that the materials in the hopper gradually gather at the outlet and are discharged through the discharge port 2212.

[0032] In some embodiments, the distance between the upper plate 102 and the lower plate 103 is adjustable. The measuring cylinder 104 includes a lower cylinder and an upper cylinder. The upper end of the upper cylinder is connected to the upper discharge hole, and the lower end of the lower cylinder is connected to the lower discharge hole. The lower end of the upper cylinder is inserted into the upper end of the lower cylinder, which can realize the distribution of materials with different dosages. By adjusting the distance, the volume of the loaded material can be adjusted.

[0033] In some embodiments, the cover plate 400 is connected to the lower plate 103 via a rotatable pin 401. A first mating surface 407 is provided on the edge of the cover plate 400 facing the rotation direction of the upper plate. A downward protruding rib 403 is provided on the end face of the cover plate 400. A second mating surface 404 is provided on the side of the protruding rib 403 facing the rotation direction of the upper plate. The first mating surface 407 and the second mating surface 404 are radially offset. A first lever 405 and a second lever 406 are provided on the frame 100. The upward extension end of the first lever 405 can interfere with the first mating surface 407 in the movement direction, which can realize the closing action of the cover plate to prepare for loading. The upward extension end of the second lever 406 can interfere with the second mating surface 404 in the movement direction, which can realize the opening action of the cover plate to discharge material. The distances from the head end of the first lever 405 and the head end of the second lever 406 to the spindle axis are not equal.

[0034] Using the above scheme, during material distribution, the rotation of the rotating shaft 101 drives the upper plate 102, lower plate 103, and measuring cylinder 104 to rotate as a whole. When the upper discharge hole on the upper plate 102 is below the feed hopper, the measuring cylinder 104, located below the outlet of the feed hopper 300, begins to load material. When the measuring cylinder 104 moves above the receiving hopper 105, the cover plate opens, and the measuring cylinder 104 begins to discharge material. After the particles are accurately measured, they enter the receiving hopper 105. After the discharge is completed, the cover plate closes. The material thickness accumulated in the feed hopper 300 is relatively thin, and the compaction degree in the vertical filling state is relatively small, which allows each measuring cylinder 104 to distribute material relatively evenly. Especially in the early and late distribution of the entire batch of materials, the error of the measuring cylinder 104 distribution is small. The belt conveyor 210 can continuously feed material into the feed hopper 300, and the material is added to the hopper 221 once, which can achieve continuous distribution for a relatively long time. This invention has a simple structure and can accurately dispense granular drugs or powders, significantly improving product qualification rate and reducing production costs. At the same time, it can still achieve quantitative material distribution even at high rotation speeds of the upper plate, thus significantly improving production efficiency.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
