Description

Technical Field

[0001] The present application relates to the technical field of traditional Chinese medicine preparation, and specifically to a preparation device for traditional Chinese medicine granules. Background Art

[0002] Chinese herbal granules refer to dry granular preparations with a certain particle size made by mixing Chinese herbal medicine extracts with suitable excipients or fine powder of medicinal materials through a certain process. Screening is an important step in the preparation of Chinese herbal granules. It helps to remove coarse and fine powders and retain particles that meet the requirements, thereby reducing the difficulty and cost of subsequent processing and improving production efficiency.

[0003] During the screening process, existing Chinese medicine granules are generally allowed to roll and slide on an inclined screen for screening. They slide naturally on the inclined screen and rely on gravity and the interaction between particles for screening. The efficiency is relatively low, especially when the particles are very sticky or the particle size distribution is uneven, which can easily lead to blockage or incomplete screening. Utility Model Content

[0004] In view of this, the purpose of the present invention is to solve the shortcomings of the background technology and to propose a preparation device for Chinese medicine granules to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the utility model provides a preparation device for Chinese medicine granules, comprising a device frame, a conveyor is provided on the device frame, a feed hopper is fixedly connected to the top of the device frame, a material guide frame is provided below the feed hopper, a coarse screen frame is provided on the device frame near the bottom end of the material guide frame, a fine screen frame is provided on the device frame near the bottom end of the coarse screen frame, a vibrating screen and material shaking mechanism for improving the screening effect of Chinese medicine granules is provided on the device frame, and both the coarse screen frame and the fine screen frame are inclined in design.

[0006] Preferably, the vibrating mesh shaking material mechanism includes a fixed box fixedly mounted on the device frame, and a motor is provided on the outer surface of the fixed box. The vibrating mesh shaking material mechanism can allow a rubber hammer to intermittently hit the screens on the coarse screen frame and the fine screen frame from bottom to top.

[0007] Preferably, the output end of the motor is fixedly connected to a lower gear, and the inner wall of the fixed box is rotatably connected to a rotating shaft.

[0008] Preferably, an upper gear is fixedly sleeved on the outer surface of the rotating shaft, the outer surface of the upper gear is meshedly connected with the outer surface of the lower gear, and an eccentric wheel is provided at one end of the rotating shaft away from the upper gear.

[0009] Preferably, a sliding rod is movably provided on the inner side of the fixed box, an outer protrusion is fixedly connected to the bottom of the sliding rod, and a spring is movably sleeved on the outer surface of the sliding rod.

[0010] Preferably, a shift rod is slidably connected to the inner wall of the fixed box, and the bottom of the shift rod is fixedly connected to the top of the sliding rod. The outer surface of the shift rod is provided with several groups of rubber hammers of different lengths.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The preparation device of traditional Chinese medicine granules realizes active pounding of the coarse screen frame and the fine screen frame through the eccentric wheel and rubber hammer mechanism driven by the motor. This mechanical vibration can effectively promote the movement of particles on the screen. Regardless of whether the blockage is caused by particle viscosity or particle size difference, the vibration can accelerate the dispersion of particles and penetration of the sieve holes, ensuring the continuity and stability of screening.

[0013] 2. The eccentric design of the preparation device for Chinese medicine granules generates periodic vibration or reciprocating motion, which subjects the particles on the screen to dynamic impact force, thereby accelerating the dispersion of the particles and their penetration through the screen holes. Compared with traditional natural sliding screening, this active agitation method can significantly improve screening efficiency, especially for particles with high viscosity or uneven particle size distribution.

[0020] Through the above technical solution, during the preparation process of Chinese medicine granules, the device first transports the particles upward through the conveyor 2 and puts them into the feed hopper 3. Then, the Chinese medicine particles will slide successively onto the coarse screen frame 5 and the fine screen frame 6 through the inclined guide frame 4. In conjunction with the vibrating screen shaking mechanism, the screens on the two groups of screen frames can be vibrated, thereby accelerating the screening of the Chinese medicine particles.

[0022] Through the above technical solution, a strip-shaped hole is opened on the outer surface of the fixed box 7 so that the shift rod 16 can smoothly pass through one side of the fixed box 7 and move up and down.

[0023] Specifically, the output end of the motor 8 is fixedly connected to the lower gear 9 , and the inner wall of the fixed box 7 is rotatably connected to the rotating shaft 11 .

[0024] Through the above technical solution, when the motor 8 drives the lower gear 9 to rotate, the upper gear 10 connected thereto will be driven to rotate synchronously, and during this process, the rotating shaft 11 will rotate accordingly.

[0025] Specifically, an upper gear 10 is fixedly sleeved on the outer surface of the rotating shaft 11 , and the outer surface of the upper gear 10 is meshedly connected with the outer surface of the lower gear 9 . An eccentric wheel 12 is provided at one end of the rotating shaft 11 away from the upper gear 10 .

[0026] Through the above technical solution, the rotating shaft 11 will drive the eccentric wheel 12 at the end to rotate during the rotation process. The eccentric design of the eccentric wheel 12 enables it to intermittently push the outer boss 14 during the rotation process. When the protruding tip of the eccentric wheel 12 completely rests on the bottom of the outer boss 14, the slide rod 13 moves upward to the maximum position.

[0027] Specifically, a slide rod 13 is movably provided on the inner side of the fixed box 7 , an outer protrusion 14 is fixedly connected to the bottom of the slide rod 13 , and a spring 15 is movably sleeved on the outer surface of the slide rod 13 .

[0031] Working principle: In the process of preparing Chinese medicine granules, the granules are first transported upward through the conveyor 2 and put into the feed hopper 3. Then the Chinese medicine granules will slide onto the coarse screen frame 5 and the fine screen frame 6 through the inclined guide frame 4. In this process, in order to improve the screening effect of the two sets of screen frames on the particles, the motor 8 can be turned on to drive the lower gear 9 to rotate. In this process, the upper gear 10 engaged with the lower gear 9 will rotate accordingly, and drive the rotating shaft 11 to rotate synchronously, and finally link the eccentric wheel 12 to rotate. When the protruding end of the eccentric wheel 12 is in continuous contact with the outer cam 14, it can be pushed, so that the outer cam 14 is pushed up, and then the linkage slide rod 13 moves up synchronously, during which the spring 15 is stressed. to compression, and when the protruding end of the eccentric wheel 12 is away from the outer cam 14, the outer cam 14 will be pushed downward by the elastic reset action of the spring 15, that is, during this process, the shift rod 16 repeatedly moves up and down intermittently in synchronization with the slide rod 13, so that the rubber hammer 17 can paddle the screens of the coarse screen frame 5 and the fine screen frame 6 in the process of moving back and forth. The vibration paddle design can clean the blockage on the screen, effectively promote the movement of particles on the screen, accelerate the dispersion of particles and penetrate the sieve holes, and whether the blockage is caused by particle viscosity or particle size difference, it can be effectively alleviated by vibration, thereby ensuring the continuity and stability of screening and significantly improving the screening efficiency.
