Description
Technical Field
[0001] This utility model relates to the field of pulverizer technology, specifically to a pulverizing device for raw materials used in powder production. Background Technology
[0002] In the production of traditional Chinese medicine (TCM) powders, the pulverization of raw materials is a crucial and fundamental step. TCM powders hold an important position in the TCM industry due to their convenient administration and rapid absorption. However, TCM raw materials are diverse in type and properties, including different parts such as roots, stems, fruits, flowers, and leaves, with significant differences in texture and hardness. This places high demands on the performance of pulverizing equipment.
[0003] Currently, existing Chinese herbal medicine (TCM) raw material pulverizing equipment has several shortcomings. Firstly, many traditional pulverizing devices employ single-roller crushing. Single-roller crushing is inefficient when dealing with complex and diverse TCM raw materials. Because the single-roller crushing method is relatively singular, it is difficult to ensure uniform crushing of raw materials with different textures, easily resulting in uneven particle size in the pulverized TCM powder. This not only affects the quality stability of the TCM powder but may also affect its efficacy in subsequent preparation processes. Furthermore, existing pulverizing devices do not provide sufficient impact and shearing between the material and the pulverizing components during the pulverizing process, leading to poor pulverization results and failing to meet the requirements of modern TCM powder production for high-quality raw materials. Utility Model Content
[0004] The purpose of this invention is to provide a raw material pulverizing device for powder production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a powder production raw material crushing device, comprising a casing and a feeding box. The feeding box is installed on the outside of the feeding channel at the top of the casing. Inside the feeding box, crushing roller one and crushing roller two are installed side by side. One end of crushing roller one and crushing roller two extends to the outside of the feeding box and is equipped with meshing gear one and gear two. The other end of crushing roller one extends to the other side of the feeding box and is equipped with a driven wheel. The output end of the feeding box is connected to the crushing chamber inside the casing through the feeding channel. A machine platform is provided on one side of the casing. A servo motor is installed on the top of the machine platform. The output end of the servo motor is connected to a rotating disk at the center of the crushing chamber through a rotating shaft. Crushing blades are evenly arranged on the edge of the rotating disk. A discharge pipe is installed at the bottom of the casing. A discharge motor is installed at one end of the discharge pipe, and the output end of the discharge motor extends into the discharge pipe and is equipped with a spiral discharge slurry.
[0006] Preferably, the bottom of the casing is provided with a discharge port that communicates with the crushing chamber. The output end of the discharge port is connected to the input end of the discharge pipe through a discharge hopper, and a screening filter screen is also installed on the inner side of the discharge port.
[0007] Preferably, a guide plate is provided at the connection between the feeding channel and the crushing chamber, and the top of the guide plate is inclined downward.
[0008] Preferably, both the chassis and the machine base are equipped with a stable support at the bottom, and a controller is installed on one side of the machine base.
[0009] Preferably, a transmission wheel is provided on the rotating shaft, and a belt is connected between the transmission wheel and the driven wheel, and a protective cover is provided on the outside of the transmission wheel, the driven wheel, and the belt.
[0010] Preferably, a protective cover is installed on the feed box outside the gear one and gear two.

[0012] This utility model provides a raw material pulverizing device for powder production, which has the following significant advantages compared with the prior art:
[0013] 1. By installing crushing roller one and crushing roller two side by side inside the feed box, and extending one end of each roller to the outside of the feed box to install meshing gear one and gear two, dual-roller coordinated crushing is achieved, significantly improving crushing efficiency.

[0014] 2. The output end of the feed box is connected to the crushing chamber through the feed channel, and a guide plate is set at the connection. The top of the guide plate is designed to be inclined downward, which effectively guides the material smoothly into the crushing chamber, reduces the accumulation and blockage of material during the feeding process, and ensures the smoothness of material conveying.
[0015] 3. The rotating disk at the center of the crushing chamber is evenly equipped with crushing blades along its edge. A servo motor drives the rotating disk to rotate at high speed via a rotating shaft, enabling the crushing blades to efficiently shear and crush the material. In addition, impact blocks are evenly installed on the inner wall of the crushing chamber, further enhancing the impact and crushing effect of the material during the crushing process, and improving the fineness and uniformity of the crushing.
[0016] 4.

The discharge motor 10 is a high-efficiency motor, and its output end extends into the interior of the discharge pipe 11, where a spiral discharge slurry 14 is installed. The function of the spiral discharge slurry 14 is to force the material out of the discharge pipe 11 by rotating, ensuring smooth material flow and avoiding blockage.
[0049] Specifically, the discharge motor 10 is mounted on the bottom of the housing 1 via a fixed bracket. The motor output shaft passes through the wall of the discharge pipe 11 and is connected to the screw discharge slurry 14.

The design angle and material selection of the discharge hopper 9 have been optimized to ensure that the material flows smoothly into the discharge pipe 11 under the action of gravity.
[0052] A screening filter 12 is installed inside the discharge port 8. The function of the screening filter 12 is to screen the crushed material to ensure that only the material that meets the particle size requirements can be discharged through the discharge port 8, while the larger particles are intercepted in the crushing chamber 2 for further crushing.
[0053] The screening filter screen 12 is made of high-strength, wear-resistant material, and its pore size is designed according to actual needs. The screening filter screen 12 is installed inside the discharge port 8 for easy replacement and maintenance.
[0054] Both the chassis 1 and the base 16 are equipped with a stabilizing bracket 13 at the bottom, and a controller 28 is installed on one side of the base 16.
[0055] Working principle: The raw materials of traditional Chinese medicine to be crushed are fed into the feed box 6 through the opening at the top. The inner wall of the feed box 6 is smooth, which reduces the frictional resistance of the material during the feeding process. The material is stored in the feed box 6 and waits to enter between crushing roller 4 and crushing roller 5. The servo motor 17 at the top of the machine base 16 is started, and the servo motor 17 drives the rotating shaft 19 to rotate. The transmission wheel 18 on the rotating shaft 19 drives the driven wheel 22 to rotate through the belt 21, thereby driving crushing roller 4 to rotate. Under the action of gear 23 and gear 25, crushing roller 4 and crushing roller 5 rotate relative to each other, realizing the uniform crushing of the raw materials.
[0056] The pre-crushed material enters the crushing chamber 2 inside the machine housing 1 from the output end of the feed box 6 through the feed channel 3. A guide plate 27 is provided at the connection between the feed channel 3 and the crushing chamber 2. The top of the guide plate 27 is inclined downward to facilitate the smooth entry of the material into the crushing chamber 2. The output end of the servo motor 17 drives the rotating disk 7 at the center of the crushing chamber 2 to rotate at high speed through the rotating shaft 19. The rotating disk 7 is located at the center of the crushing chamber 2, and its edge is evenly provided with crushing blades 15. The crushing blades 15 are made of special alloy material with sharp edges, which can efficiently shear and crush the material. Impact blocks 26 are evenly installed on the inner wall of the crushing chamber 2. The installation position of the impact blocks 26 is matched with the rotation trajectory of the crushing blades 15. While the material is being sheared by the crushing blades 15, it will also collide with the impact blocks 26, further enhancing the crushing effect. The impact blocks 26 are rectangular block structures made of high-hardness wear-resistant material. They are fixed to the inner wall of the crushing chamber 2 by bolts. The installation position is evenly distributed to ensure that the material is evenly stressed during the crushing process.
[0057] The thoroughly pulverized material is discharged from the outlet 8 at the bottom of the pulverizing chamber 2. A screening screen 12 is installed inside the outlet 8. The screening screen 12 is made of high-strength, wear-resistant material, and its aperture is designed according to actual needs. It can screen the pulverized material, ensuring that only materials meeting the particle size requirements can be discharged through the outlet 8, while larger particles are intercepted in the pulverizing chamber 2 for further pulverization. Materials meeting the particle size requirements enter the discharge hopper 9 through the outlet 8. The design angle and material selection of the discharge hopper 9 are optimized to ensure that the material flows smoothly into the discharge pipe 11 under gravity. A discharge motor 10 is installed at one end of the discharge pipe 11. The output end of the discharge motor 10 extends into the interior of the discharge pipe 11 and is equipped with a spiral discharge slurry 14. After the discharge motor 10 is started, the spiral discharge slurry 14 rotates, forcibly discharging the material from the discharge pipe 11, ensuring smooth material flow and avoiding blockage.
