Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically a sieving device for the production of traditional Chinese medicine granules. Background Technology

[0002] Traditional Chinese medicine granules are produced by extracting and concentrating single-herb medicinal slices according to traditional standards, and are intended for use in clinical prescriptions in traditional Chinese medicine. During the production of traditional Chinese medicine granules, the extracted and concentrated materials typically form granular finished products. However, due to the complexity of the production process and the inherent characteristics of the materials, variations in granule size are inevitable. For some granular traditional Chinese medicines, these inconsistent sizes after production can affect subsequent prescription use and quality control. Therefore, it is necessary to use a sieving device to finely separate the granules to ensure uniformity and consistency. The sieving device plays a crucial role in the production of traditional Chinese medicine granules, effectively separating granules of different sizes to ensure that the product meets specifications.

[0003] In existing technologies, screening devices used in the production of traditional Chinese medicine granules generally suffer from low filtration efficiency and easy clogging of the screen holes. Due to the varying sizes and irregular shapes of the granules, some may become stuck in the screen holes during screening, causing blockage. This blockage not only reduces screening efficiency but also affects the normal operation of the equipment, requiring regular manual cleaning of the screen. Manual cleaning is not only slow and cumbersome, increasing production costs and time delays, but also requires the equipment to be paused during cleaning, further reducing overall screening efficiency and slowing down the processing progress. Therefore, this invention proposes a screening device for the production of traditional Chinese medicine granules to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a screening device for the production of traditional Chinese medicine granules, so as to solve the problems mentioned in the background art.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 4This utility model provides a technical solution: a screening device for the production of traditional Chinese medicine granules, comprising: a box body 1, which serves as the main support for the entire device and is used to hold materials; a box cover 2 is detachably installed on the upper side of the box body 1, which covers the upper side of the box body 1 to reduce excessive dust diffusion during screening and facilitates the subsequent removal of materials from the screen frame 4; a feeding pipe 3 is fixedly installed on the top of the box cover 2 for easy addition of materials; the box body 1 is provided with a horizontally movable screen frame 4, and a driving component for driving the horizontal movement of the screen frame 4 is connected to the upper side of the screen frame 4; a return spring 5 is provided on one side of the screen frame 4, and one end of the return spring 5 is fixedly connected to the inner wall of the box body 1; when the screen frame 4 moves horizontally, it compresses the return spring 5, and the return spring 5 is released by the reverse elastic force of the return spring 5. The screen frame 4 is reset. An anti-clogging component is provided at the bottom of the screen frame 4. The anti-clogging component can reduce the occurrence of important particles getting stuck and clogging the screen holes of the screen frame 4, thereby improving the screening efficiency of the screen frame 4. The anti-clogging component includes two counter-symmetrically arranged meshing belts 6. Several meshing wheels 7 are meshed in the meshing belts 6. The meshing belts 6 and meshing wheels 7 mesh and drive each other. A rotating shaft 8 is fixedly sleeved in the several meshing wheels 7. A brush head 9 is fixedly connected to the outer ring surface of the rotating shaft 8. The rotation of the rotating shaft 8 drives the brush head 9 to repeatedly brush the bottom of the screen frame 4. The two sides of the rotating shaft 8 are rotatably installed on the side wall of the box 1. The box 1 limits the rotation of the rotating shaft 8 and improves its stability during rotation. A guide box 10 is provided at the bottom of the brush head 9. The guide box 10 guides the screened material, thereby facilitating the unified collection of subsequent materials.

[0024] In use, the Chinese herbal medicine granules to be screened are added through the feeding pipe 3. The drive assembly drives the screen frame 4 to move laterally within the housing 1. As the screen frame 4 moves towards the return spring 5, the return spring 5 is gradually compressed. When the return spring 5 is compressed to a certain extent, it releases the reverse elastic force, causing the screen frame 4 to return to its original position. This process is repeated to achieve repeated movement of the screen frame 4, causing the Chinese herbal medicine granules inside to roll during the movement of the screen frame 4, thereby screening the material. When the screen frame 4 moves, the drive shaft 8 in the middle position rotates. The shaft 8 in the middle position drives the other shafts 8 to rotate through the meshing transmission of the meshing belt 6 and the meshing wheel 7. Under the rotation of the shafts 8, the brush head 9 rotates, cleaning the bottom of the screen frame 4 and preventing some of the Chinese herbal medicine granules from clogging the screening holes of the screen frame 4, thus improving the screening efficiency of the screen frame 4.

[0025] The outer wall of the box cover 2 has recessed holes 11 on both sides. The top two sides of the outer wall of the box body 1 are fixedly connected to the limiting plate 12. The surface of the limiting plate 12 has a limiting hole 13. The recessed hole 11 is slidably inserted into one end of the limiting pin 14. The recessed hole 11 and the limiting hole 13 limit the limiting pin 14. The other end of the limiting pin 14 passes through the limiting hole 13 and is fixedly connected to one end of the small spring 15. The limiting pin 14 is slidably connected to the limiting hole 13. The other end of the small spring 15 is fixedly connected to the surface of the limiting plate 12.

[0026] In the initial state, the limiting pin 14 is inserted into the recess 11. When the screening is completed and the material inside the screen frame 4 needs to be cleaned and collected, the two limiting pins 14 are pulled in opposite directions to make the limiting pins 14 slide out of the recess 11. At this time, the small spring 15 is stretched, thereby releasing the limiting of the box cover 2. The box cover 2 can then be removed, so that the material inside the screen frame 4 can be collected. Then, when installing the box cover 2, the box cover 2 is placed on the top of the box body 1, the limiting pin 14 is released, and the limiting pin 14 is inserted into the recess 11 under the reverse elastic force of the small spring 15, thus completing the limiting of the box cover 2.

[0027] Limiting sleeves 16 are fixedly fitted on both sides of the top of the screen frame 4. The limiting sleeves 16 are slidably fitted on the limiting rods 17, which limit the limiting sleeves 16. The two ends of the limiting rods 17 are fixedly connected to the inner wall of the housing 1. The drive assembly includes an upper motor, which is electrically connected to an external control device. The output end of the upper motor is fixedly connected to one end of the drive shaft 18. The other end of the drive shaft 18 is rotatably fitted inside the side wall of the housing 1, and the housing 1 limits the drive shaft 18. Two half gears 19 are fixedly fitted on the drive shaft 18. A rack 20 meshes with the lower side of the two half gears 19. The rack 20 is fixedly installed on the limiting sleeves 16.

[0028] When it is necessary to screen Chinese medicine granules, the upper motor is started, which drives the drive shaft 18 fixedly connected to its output end to rotate. The drive shaft 18 then drives the half gear 19 to rotate. Since the screen frame 4 is connected to the rack 20 through the half gear 19, the screen frame 4 is driven to move laterally inside the housing 1 under the action of the rotation of the half gear 19. When the screen frame 4 moves closer to the return spring 5, the return spring 5 is compressed. Since the half gear 19 has half the number of teeth, when the half gear 19 disengages from the rack 20, the return spring 5 releases the thrust to reset the screen frame 4. This process is repeated to realize the reciprocating motion of the screen frame 4, which in turn causes the Chinese medicine granules inside the screen frame 4 to roll as the screen frame 4 moves, thus completing the screening of the Chinese medicine granules.

[0029] The upper surface of the guide box 10 is fixedly connected to the lower surface of the box body 1. A driven gear 21 is fixedly sleeved on one end of the rotating shaft 8 located in the middle position. The upper side of the driven gear 21 meshes with the drive gear 22 for transmission. The drive gear 22 is fixedly connected to the output end of the lower motor. The lower motor is fixedly installed on the outer wall of the box body 1.

[0030] The feed box 10 provides fixed support for the box body 1. By driving the lower motor, the lower motor drives the drive gear 22 fixedly connected to its output end to rotate. The drive gear 22 meshes with the driven gear 21 for transmission. The driven gear 21 is fixedly sleeved on the rotating shaft 8 located in the middle position. The rotating shaft 8 in the middle position drives the other rotating shafts 8 to rotate through the meshing belt 6 and meshing wheel 7. Thus, the rotation of the rotating shaft 8 drives the brush head 9 to rotate. The brush head 9 cleans the bottom of the screen frame 4, thereby preventing some particles of the Chinese herbal raw materials from clogging the screening holes of the screen frame 4 and improving the screening efficiency of the screen frame 4.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
