Abstract
Description
Technical Field
[0001] This application relates to the field of traditional Chinese medicine processing equipment technology, and in particular to a traditional Chinese medicine drug pulverizing device. Background Technology
[0002] In the field of traditional Chinese medicine (TCM), drug pulverization is a crucial step in drug preparation, directly impacting subsequent processing and efficacy. Traditional TCM pulverization devices mostly employ a single pulverizing structure, subjecting drugs to only one pulverization process. This often fails to achieve the desired fineness, making it unsuitable for the diverse needs of different drug formulations. Furthermore, these devices lack effective sieving capabilities, resulting in uneven particle size and a large number of unsuitable coarse particles. This not only affects drug quality but also leads to waste of raw materials. In addition, the pulverizing components of traditional devices are often difficult to disassemble and replace. After prolonged use and significant wear, repair and maintenance costs are high, impacting the device's efficiency and pulverization effectiveness. Utility Model Content

[0035] Example 3:
[0036] like Figure 1 , 6As shown, this utility model discloses another technical solution, a traditional Chinese medicine drug pulverizing device, which differs from embodiment 1 in that the upper part of the sieving frame 10 is open, and the bottom of the sieving frame 10 is provided with a plurality of evenly distributed sieving holes 24. The two opposite side walls of the sieving frame 10 are each equipped with a slider 26 by means of a fixing plate 25 and bolts.

[0038] This application may be equipped with a PLC controller, which is electrically connected to the drive motor and controls its operation. Its specific structure, circuit connection method and working principle are all prior art and are not within the protection scope of this application. Those skilled in the art can deduce them by conventional means, and will not be described in detail here.
[0039] This application provides a traditional Chinese medicine pulverizing device. In use, the raw materials to be pulverized are placed in the feed hopper 4. Depending on the quantity of medicine to be processed, one or two grinding structures are used. The first drive motor 17 is started, which drives the rotating shaft 13 to rotate via the driving pulley 18, the transmission belt 20, and the driven pulley 19. This causes the support plate 14 and the grinding blade 15 fixed on the rotating shaft 13 to rotate at high speed. After the medicine enters the grinding chamber 8 of the grinding hopper 5 from the feed hopper 4, it is pulverized by the grinding blade 15. The crushed drug particles fall through the filter screen 7 into the first feed hopper 6, and then through the receiving hopper 12 to the screening frame 10. The second drive motor 28 is started, which drives the eccentric rod 29 to rotate. The eccentric rod 29 drives the screening frame 10 to move back and forth along the length direction on the slide rail 27 through the linkage rod 30. During the movement, the fine particles that meet the requirements fall through the screening holes 24 into the second feed hopper 11 below, while the coarse particles that do not meet the requirements remain in the screening frame 10 and can be crushed again.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
