[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] As described in the background art, a novel multi-stage pulverizer for traditional Chinese medicine is used. Different medicinal materials require different levels of fineness in grinding, and the above-mentioned device is difficult to meet the output requirements of medicinal materials with different particle sizes. Moreover, when the medicinal materials are over-fed, it is easy to cause the equipment to jam, which often requires shutdown for maintenance and affects the pulverization efficiency of the medicinal materials.

[0026] To solve this technical problem, this utility model provides an adjustable multi-stage pulverizer, which is applied to the pulverization of medicinal materials. Example 1

[0027] For details, please refer to Figure 1-6 The adjustable multi-stage pulverizer specifically includes: a frame 1, a shell 2 fixedly mounted on the frame 1, an adjustable grinding chamber mechanism installed inside the shell 2, and a pulverizing roller rotatably mounted on the frame 1.

The grinding cavity adjusting blocks 6 are stacked together to form a polygonal grinding cavity 11. The crushing roller is rotatably installed within the polygonal grinding cavity 11. Multiple limiting screws 12 are screwed onto the adjusting plate 5. Furthermore, the second sliding groove 8 forms an angle of 30°-80° with the corresponding radial line on the adjusting plate 5; the cross-section of the stacked portion of each grinding cavity adjusting block 6 is an equilateral triangle; the adjusting plate 5 is locked to the shell 2 by the limiting screws 12; the drive motor 3 is a frequency-modulated motor; and the adjusted adjusting plate 5 is fixedly connected to the shell 2 by the limiting screws 12.

[0028] For details, please refer to Figure 3 and Figure 9 A support 20 is fixedly mounted on the adjustment plate 5, and the bottom of the drive shaft 13 is rotatably mounted on the support 20; furthermore, the drive shaft 13 is rotatably connected to the support 20 through bearing seats, etc.

[0029] For details, please refer to Figure 1 or Figure 3 The bottom of the frame 1 is provided with a feeding hopper 21; furthermore, the feeding hopper 21 is used to receive the crushed medicinal materials.

[0030] The adjustable multi-stage pulverizer provided in this embodiment can limit the bottom of the drive shaft 13 under the action of the support 20, so as to improve the rotational stability of the drive shaft 13 and reduce the amount of shaking of the drive shaft 13; while the hopper 21 can discharge the pulverized medicinal materials from the bottom of the frame 1 to the outside, so that the operator can receive the pulverized medicinal materials. Example 2

[0031] The adjustable multi-stage pulverizer provided in Example 1 has been further optimized. For details, please refer to [link / reference needed]. Figure 3 and Figure 9 The crushing roller includes a drive shaft 13 and multiple crushing discs 14. The multiple crushing discs 14 are evenly distributed along the axial direction of the drive shaft 13. Multiple circumferentially distributed crushing heads 15 are provided on the crushing discs 14. The crushing heads 15 on the multiple crushing discs 14 are gradually staggered from top to bottom on the drive shaft 13. Furthermore, the corresponding crushing heads 15 on the multiple crushing discs 14 are arranged in a spiral linear arrangement from the upper part to the lower part of the drive shaft 13. The output shaft of the drive motor 3 is connected to the drive shaft 13 for transmission.

[0032] For details, please refer to Figure 3 The frame 1 is equipped with a housing 16 located above the polygonal grinding chamber 11 and a feeding hopper 17 for feeding material into the housing 16. The inside of the feeding hopper 17 is connected to the inside of the housing 16. Furthermore, the inner bottom wall of the feeding hopper 17 gradually slopes into the housing 16.

[0033] For details, please refer to Figure 3 , Figure 7 and Figure 8 Multiple slitting blades 18 are mounted on the drive shaft 13 and fit into the inner wall of the housing 16. The multiple slitting blades 18 are evenly distributed around the drive shaft 13. Furthermore, the slitting blades 18 are located inside the housing 16 and are used for the initial slitting of the medicinal materials entering the housing 16.

[0034] For details, please refer to Figure 3A sealing cap 19 is installed between the fixed plate 4 and the shell 16; furthermore, the sealing cap 19 is used to seal the circumferential seam between the fixed plate 4 and the shell 16 to reduce the outward escape of the broken powder from the circumferential seam between the fixed plate 4 and the shell 16.

[0035] The adjustable multi-stage pulverizer provided in this embodiment, during the rotation of the drive shaft 13 driven by the drive motor 3, causes the pulverizing disc 14 to rotate at high speed along with the drive shaft 13. As the medicinal materials fall from the polygonal grinding chamber 11, they contact the pulverizing blades 15 on the pulverizing disc 14, which cut the medicinal materials. Multiple pulverizing discs 14 progressively pulverize the medicinal materials, achieving multi-stage pulverization and significantly improving the pulverization effect. Furthermore, the drive motor 3 is a variable frequency motor, allowing adjustment of the pulverizing roller speed by controlling the speed of the drive motor 3. The fineness of the pulverized medicinal materials can be further adjusted to meet the pulverization requirements of different particle sizes in the production of traditional Chinese medicine. The medicinal materials can be fed into the shell 16 through the feeding hopper 17 to improve the convenience of feeding. After the medicinal materials enter the shell 16, the drive shaft 13 drives the slitting blade 18 to rotate. The slitting blade 18 performs preliminary slitting of the medicinal materials, reducing the occurrence of equipment jamming caused by excessively large particle size of the medicinal materials entering the polygonal grinding chamber 11. Under the action of the sealing cover 19, the dust generated during the pulverization process can be reduced from escaping from the annular seam between the fixed plate 4 and the shell 16.

[0036] The adjustable multi-stage pulverizer provided by this utility model is used as follows: Herbal materials are fed into the housing 16 from the feeding hopper 17. The drive motor 3 drives the drive shaft 13 to rotate, which in turn drives the slitting blade 18 to rotate. The slitting blade 18 initially slits the herbal materials, and the initially slit particles enter the multi-sided grinding chamber 11. The drive shaft 13 drives the pulverizing discs 14 to rotate, and the pulverizing blades 15 on each pulverizing disc 14 further pulverize the herbal materials. The pulverized herbal materials fall into the discharge hopper 21, where they are collected. When it is necessary to further pulverize the herbal materials... When adjusting the diameter, the second sliding column 10 slides in the corresponding second sliding groove 8 by rotating the adjustment disk 5, while the first sliding column 9 slides synchronously in the corresponding first sliding groove 7. Multiple sets of grinding chamber adjustment blocks 6 synchronously converge or move away from the center of the shell cylinder 2, causing the internal dimensions of the polygonal grinding chamber 11 to change. This allows for adaptive adjustment of the distance between the crushing roller and the polygonal grinding chamber 11, and synchronous adjustment of the speed of the drive motor 3, thereby adjusting the contact frequency between the medicinal material and the crushing blade 15, so that the medicinal material is cut into different particle sizes, thus meeting the different crushing particle size requirements of the medicinal material.
