Abstract
Description
Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically a pulverizer for ultrafine powder of traditional Chinese medicine. Background Technology
[0002] Pulverizing Chinese medicinal materials is an important step in the production process of Chinese medicine preparations. Pulverizing increases the surface area of the medicine, promotes its dissolution, and improves its solubility and absorption rate, thereby enhancing its efficacy.
[0003] Currently, the grinding process of Chinese medicinal herbs requires the use of a grinder. Most existing grinders consist of a grinding chamber and grinding blades. A motor drives a single set of grinding blades to rotate, thereby cutting and grinding the medicinal herbs. However, the cutting precision of the grinding blades is limited, resulting in insufficient fineness of the powder, which in turn affects the efficacy of the subsequent Chinese medicine preparations. Therefore, we propose a grinder for ultrafine powder of Chinese medicinal herbs. Utility Model Content
[0004] The purpose of this invention is to provide a pulverizer for ultrafine powder of Chinese medicinal materials, which solves the problems mentioned in the background art.

[0006] The crushing assembly includes a turntable, which is fixedly connected to a rotating shaft. T-shaped teeth are fixed on all four sides of the outer wall of the turntable, and a first square tooth is fixed between two adjacent T-shaped teeth. A bolt post is fixed in the middle of one side wall of the turntable. Two staggered blades are fitted on the outer wall of the bolt post. A matching nut is engaged on the outer wall of the bolt. A matching filter screen is fixed on the inner wall of the crushing chamber, and the mesh of the filter screen is a conical hole. A discharge pipe is fixedly connected to the bottom of the crushing chamber, and the discharge pipe passes through the carrier and extends to one side of the carrier.
[0007] By adopting the above technical solution, the raw materials of Chinese medicinal herbs are first introduced into the inner cavity of the crushing box. Then, the first transmission wheel is driven to rotate by the servo motor, and the second transmission wheel is driven to rotate by the transmission belt, thereby driving the crushing component to rotate. Then, by using T-shaped teeth, first square teeth, and blades, multiple crushing is achieved, which helps to improve the fineness of the crushed material. The crushed material can be filtered through the filter screen, so that qualified material can pass through the filter screen and be discharged through the discharge pipe. When the material passes through the mesh, the conical hole design helps to reduce clogging.
[0008] In a preferred embodiment of the present invention, a feed hole is provided in the middle of the outer wall of the box cover, and a feed pipe is fixedly connected to the outer end of the feed hole. A feed tray is fixedly connected to the upper opening of the feed pipe.
[0009] By adopting the above technical solution, the material is introduced into the feeding tray, so that the material in the feeding tray can enter the feeding hole through the feeding pipe and then enter the crushing box for crushing.
[0010] In a preferred embodiment of this utility model, the inner wall of the box cover is fixed with a second square tooth on all four sides.
[0011] By adopting the above technical solution, the second square teeth are used to cut and grind the raw materials by alternating with the first square teeth, which helps to further improve the fineness of the raw material crushing.
[0012] In a preferred embodiment of this utility model, blades are fixed on all four sides of the other side wall of the turntable.
[0013] By adopting the above technical solution, the blades can be used to blow air during the rotation of the turntable, thereby improving the tumbling effect of the material in the crushing box and further enhancing the crushing effect. At the same time, the blowing air can apply pressure to the material in the mesh of the filter screen, which is conducive to improving the discharge effect and avoiding clogging.
[0014] In a preferred embodiment of this utility model, the turntable has strip-shaped holes on all four sides of its outer wall.
[0015] By adopting the above technical solution, the design of the strip-shaped holes allows airflow to pass through the turntable, while also reducing the weight of the turntable and lowering the burden on the servo motor.

[0034] Please see Figure 1-6 This utility model provides a technical solution: a pulverizer for ultrafine powder of Chinese medicinal materials, including a frame 1, a pulverizing box 2 fixed on the top of the frame 1, a box cover 3 hinged to one side wall of the pulverizing box 2, a rotating shaft 16 rotatably passing through the other side wall of the pulverizing box 2, a pulverizing component fixedly connected to the inner end of the rotating shaft 16, a second transmission wheel 15 fixedly connected to the outer end of the rotating shaft 16, a servo motor 12 fixed on the cross brace of the inner cavity of the frame 1, a first transmission wheel 13 fixed to the outer end of the transmission shaft of the servo motor 12, the first transmission wheel 13 and the second transmission wheel 15 being connected by a transmission belt 14, the transmission belt 14 passing through a through hole 11 opened at the top of the frame 1;
[0035] The crushing assembly includes a turntable 21, which is fixedly connected to a rotating shaft 16. T-shaped teeth 22 are fixed on all four sides of the outer wall of the turntable 21. A first square tooth 23 is fixed between two adjacent T-shaped teeth 22. A bolt post 26 is fixed in the middle of one side wall of the turntable 21. Two staggered blades 27 are fitted on the outer wall of the bolt post 26. A matching nut is engaged on the outer wall of the bolt 26. A matching filter screen 25 is fixed on the inner wall of the crushing box 2. The mesh of the filter screen 25 is a conical hole. A discharge pipe is fixedly connected to the bottom of the crushing box 2. The discharge pipe passes through the carrier frame 1 and extends to one side of the carrier frame 1.
[0036] In actual use, the raw materials of Chinese medicinal herbs are first introduced into the inner cavity of the crushing box 2. Then, the servo motor 12 drives the first transmission wheel 13 to rotate, and the transmission belt 14 drives the second transmission wheel 15 to rotate, thereby driving the crushing component to rotate. Then, the T-shaped teeth 22, the first square teeth 23, and the blades 27 are used to achieve multiple crushing, which helps to improve the fineness of the crushed material. The crushed material can be filtered through the filter screen 25, so that qualified material can pass through the filter screen 25 and be discharged through the discharge pipe. When the material passes through the mesh, the conical hole setting helps to reduce clogging.
[0037] Furthermore, blades 28 are fixed on all four sides of the other side wall of the turntable 21;
[0038] It should be understood that during the rotation of the turntable 21, the blades 28 can be used to blow air, thereby improving the tumbling effect of the material in the crushing box 2, thus further improving the crushing effect. At the same time, the blowing air can apply pressure to the material in the mesh of the filter screen 25, which is conducive to improving the discharge effect and avoiding clogging.
[0039] Furthermore, a protective cover 17 is fixed to one side of the top of the carrier 1. The protective cover 17 covers the second transmission wheel 15, and the protective cover 17 can provide shielding, thereby improving safety.
[0040] It is worth mentioning that the turntable 21 has strip-shaped holes 24 on all four sides of its outer wall. The design of the strip-shaped holes 24 allows air to pass through the turntable 21, while also reducing the weight of the turntable 21 and reducing the burden on the servo motor 12.
[0041] like Figure 1 and 2 As shown; a feed hole 33 is provided in the middle of the outer wall of the box cover 3, and a feed pipe 31 is fixedly connected to the outer end of the feed hole 33. A feed tray 32 is fixedly connected to the upper opening of the feed pipe 31.
[0042] By introducing the material into the feed tray 32, the material in the feed tray 32 can enter the feed hole 33 through the feed pipe 31 and then enter the crushing box 2 for crushing.
[0043] Furthermore, the inner wall of the box cover 3 is fixed with second square teeth 34 on all four sides. The second square teeth 34 are designed to cut and grind the raw materials by interlacing with the first square teeth 23, which helps to further improve the fineness of the raw material crushing.
[0044] It should be noted that the filter holes on the outer wall of the filter screen 25 are tapered holes. The tapered holes allow the material to have greater contact with the air when passing through the filter holes, which is conducive to the diffusion of the material and helps to avoid clogging.
[0045] The implementation principle of the ultrafine powder pulverizer of traditional Chinese medicine in this application is as follows: First, the material is introduced into the feeding tray 32, so that the material in the feeding tray 32 can enter the feeding hole 33 through the feeding pipe 31 and then enter the pulverizing box 2. Then, the servo motor 12 drives the first transmission wheel 13 to rotate, and the transmission belt 14 drives the second transmission wheel 15 to rotate, thereby driving the pulverizing component to rotate. Then, the T-shaped teeth 22, the first square teeth 23, and the blades 27 are used to achieve multiple pulverization, which is conducive to improving the fineness of the pulverized material. At the same time, the second square teeth 34 and the first square teeth 23 are used to cut and grind, which is conducive to further improving the fineness of the raw material. The pulverized raw material can be filtered through the filter screen 25, so that the qualified material can pass through the filter screen 25 and be discharged through the discharge pipe.
