Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulverizing devices, specifically to a pulverizing device for traditional Chinese medicine. Background Technology
[0002] Traditional Chinese medicine (TCM) pulverizing devices play a crucial role in the pharmaceutical and processing of TCM. Their core function is to precisely pulverize various TCM herbs into a fine powder that meets the requirements of subsequent processing. In practice, these devices primarily rely on the high-speed operation of toothed hammers, blades, or the coordinated action of moving and stationary blades. Utilizing powerful impact, shearing, and grinding forces, they rapidly break the TCM herbs into tiny particles. Some devices also employ airflow to quickly discharge and collect these pulverized particles. Through this process, the effective components of the TCM herbs are fully released, significantly improving bioavailability and therapeutic efficacy. This also facilitates the preparation of diverse drug dosage forms such as tablets, capsules, and granules, and lays a solid foundation for the research and development of new TCM drugs.
[0003] However, most traditional grinding devices on the market employ a single type of grinding blade structure, which exhibits significant limitations when dealing with medicinal herbs with special characteristics such as long roots and high fiber content. This significantly reduces the grinding efficiency of the blades, failing to achieve the expected fineness and uniformity standards. Furthermore, when the device is tilted for discharge, the existing positioning mechanisms are unreliable. When material is being ground or discharged from the tilted outlet, the lack of precise and effective positioning measures leads to material scattering and deviation, making it difficult for the material to accurately fall into the designated collection container or conveying path. This not only affects the smoothness and stability of the discharge process but may also lead to material waste, reduced processing efficiency, and even adverse effects on subsequent processing steps.

[0005] To address the shortcomings of existing technologies, this utility model provides a Chinese herbal medicine pulverizing device, which has the advantages of multi-level pulverization and maintaining device stability, thereby solving the problems mentioned in the background technology.
[0006] (II) Technical Solution
[0007] To achieve the advantages of multi-level pulverization and maintaining device stability, the specific technical solution adopted by this utility model is as follows: A Chinese herbal medicine pulverizing device includes a frame and a pulverizing cylinder. The pulverizing cylinder is installed on the top of the frame, and a motor is fixedly installed at the bottom of the pulverizing cylinder. A rotating column is fixed on the surface of the motor housing, and one end of the rotating column is rotatably connected to the frame through a bearing. A cylinder cover is threadedly installed at the opening on the top surface of the pulverizing cylinder, and a handle is welded to the top surface of the cylinder cover. The output end of the motor extends to the inside of the pulverizing cylinder, and a main pulverizing blade and an auxiliary pulverizing blade are sequentially installed on the output end of the motor from bottom to top. Fastening screws connected to the output end of the motor are inserted through the surfaces of the main pulverizing blade and the auxiliary pulverizing blade. The main pulverizing blade consists of two arc-shaped blades with opposite inclination directions and sharp blades symmetrically welded to their sides. The two ends of the auxiliary pulverizing blade are provided with upwardly inclined blunt blades.
[0008] Furthermore, a perforated positioning block is welded to the lower side of the motor, and a locking component is welded to the right side wall of the frame corresponding to the perforated positioning block. Two positioning posts are inserted into the locking component, and a support ring is welded to the surface of each positioning post. A spring that abuts against the support ring is also fitted onto the surface of each positioning post. One end of the positioning post is inserted into the perforated positioning block, and a handle that abuts against the outer surface of the locking component is fixed to the other end of the positioning post. Limiting holes are opened on the surface of the positioning post.
[0009] Furthermore, the handle on the top surface of the cylinder cover has a U-shaped structure, and tempered glass is embedded in the top surface of the cylinder cover. A threaded ring is welded to the bottom of the cylinder cover, and an external thread is provided on the outer surface of the opening on the top surface of the crushing cylinder corresponding to the threaded ring. Hand-held parts are welded to both the left and right sides of the handle.
[0010] Furthermore, a support bracket is welded to the middle position of the side of the frame, and the support bracket is composed of a vertical part and an inclined part, and the inclined part of the support bracket is set corresponding to the crushing cylinder.
[0011] Furthermore, a control switch is fixedly installed on the left side wall of the frame, and the output terminal of the control switch is electrically connected to the motor.
[0012] Furthermore, one side of the support ring contacts the inner wall of the locking assembly, and the other side of the support ring abuts against one end of the spring, while the other end of the spring abuts against the inner wall of the locking assembly.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a Chinese herbal medicine pulverizing device, which has the following beneficial effects:
[0015] (1) This utility model effectively solves the problem of single pulverizing blades in traditional devices by using a synergistic design of the main pulverizing blade and the auxiliary pulverizing blade. The main pulverizing blade consists of two arc-shaped blades with opposite inclination directions and symmetrically welded spike-shaped blades on the sides. The arc-shaped blades can quickly cut and tear long-rooted Chinese medicinal materials, while the spike-shaped blades can accurately pierce and crush fibrous medicinal materials, preventing them from tangling around the rotating shaft. The upward-inclined blunt blades at both ends of the auxiliary pulverizing blade can perform secondary grinding and homogenization on the initially pulverized material, realizing multi-level pulverizing operations. This combination not only significantly improves pulverizing efficiency but also ensures that the pulverized Chinese medicinal materials have uniform particle size and meet the fineness standards, satisfying the requirements of different processing scenarios for medicinal powder.
[0016] (2) This utility model perfectly solves the problem of unreliable positioning when the traditional device is tilted during material discharge by using the elastic insertion design of the locking component. The insertion and cooperation between the perforated positioning block and the positioning column, combined with the continuous force of the spring on the support ring, maintains the stability and reliability of the crushing cylinder in the vertical state, meeting the requirements of Chinese medicine crushing. By pulling the positioning column with the handle, the spring can be quickly compressed, causing the positioning column to disengage from the perforated positioning block, thus quickly unlocking the crushing cylinder. Combined with the leaning bracket with the inclined part, it is easy to maintain the stability of the crushing cylinder in the tilted material discharge state. With this structure, the device maintains reliable operation in both crushing and tilted material discharge states, reducing material waste and improving processing efficiency.

[0025] According to an embodiment of this utility model, a Chinese herbal medicine pulverizing device is provided.
[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a traditional Chinese medicine pulverizing device according to an embodiment of the present invention includes a frame 1 and a pulverizing cylinder 2. The pulverizing cylinder 2 is installed on the top of the frame 1, and a motor 3 is fixedly installed on the bottom of the pulverizing cylinder 2. A rotating column 7 is fixed on the surface of the housing of the motor 3, and one end of the rotating column 7 is rotatably connected to the frame 1 through a bearing. A cylinder cover 5 is threadedly installed at the opening on the top surface of the pulverizing cylinder 2, and a handle 11 is welded to the top surface of the cylinder cover 5. The output end of the motor 3 extends to the inside of the pulverizing cylinder 2, and a main pulverizing blade 14 and an auxiliary pulverizing blade 15 are sequentially installed on the output end of the motor 3 from bottom to top. Fastening screws 17 connected to the output end of the motor 3 are inserted through the surfaces of the main pulverizing blade 14 and the auxiliary pulverizing blade 15. The main pulverizing blade 14 is composed of two arc-shaped blades with opposite inclination directions and sharp blades 16 symmetrically welded to its sides. The two ends of the auxiliary pulverizing blade 15 are provided with upwardly inclined blunt blades. The pulverizing cylinder 2 is made of food-grade stainless steel, and the inner wall is polished to avoid adhesion during the pulverization of traditional Chinese medicine and to facilitate subsequent cleaning. The bottom of the crushing cylinder 2 is fixedly mounted with a motor 3 by a bolt assembly. The motor 3 is a three-phase asynchronous motor with overheat protection function, which can maintain stable performance under long-term high-load operation. The locking action of the fastening screw 17 can effectively prevent the blade from loosening or shifting during high-speed rotation. The main crushing blade 14 consists of two arc-shaped blades with opposite inclination directions. The blades of the arc-shaped blades are treated with high-frequency quenching, and the hardness can reach HRC55-60, which can easily cut hard Chinese medicinal roots and stems. The sides of the blades are symmetrically welded with spike-shaped blades 16. The spike-shaped blades 16 have a conical structure and a length of 3-5cm, which can penetrate into the interior of the Chinese medicinal fiber for crushing, and prevent fibrous medicinal materials from getting tangled in the rotating shaft. The auxiliary crushing blades 15 have blunt blades at both ends that are inclined upward at 15°-20°. The surface of the blunt blades is rounded, which can gently grind and homogenize the initially crushed material during rotation, further improving the uniformity of the crushed particles. The rotating column 7 is made of high-hardness alloy material. One end of it is rotatably connected to the frame 1 through a precision bearing. The bearing is filled with wear-resistant grease to ensure that the crushing cylinder 2 can rotate flexibly around the rotating column 7 as the axis, which provides convenience for the subsequent tilting discharge operation.
[0027] Please refer to Figure 1 and Figure 4A perforated positioning block 9 is welded to the lower side of the motor 3. A locking assembly 10 is welded to the right side wall of the frame 1 corresponding to the perforated positioning block 9. Two positioning posts 19 are inserted and installed on the locking assembly 10. Each positioning post 19 has a support ring 20 welded to its surface, and a spring 21 that abuts against the support ring 20 is fitted on the surface of each positioning post 19. One end of the positioning post 19 is inserted into the perforated positioning block 9, and the other end of the positioning post 19 is fixed with a handle 18 that abuts against the outer surface of the locking assembly 10. A limit hole 22 is opened on the surface of the positioning post 19. The perforated positioning block 9 is made of thick-walled steel plate. The surface of the pulverizing cylinder 2 is uniformly distributed with multiple positioning holes, and the hole positioning accuracy is controlled within ±0.1mm. The locking component 10 is a hollow rectangular frame structure with two parallel positioning posts 19 inserted inside. The positioning posts 19 are made of chrome-plated round steel with a surface smoothness of Ra0.8μm to ensure smooth sliding. The support ring 20 is coaxially aligned with the positioning posts 19, and each positioning post 19 is fitted with a spring 21 that abuts against the support ring 20. The spring 21 is a high-strength compression spring with an elastic coefficient of 50-80N / mm, which can provide a stable elastic force. One end of the positioning post 19 can be precisely inserted into the positioning hole of the perforated positioning block 9 to lock the angle of the pulverizing cylinder 2, and the other end is fixed by welding to a handle 18 that abuts against the outer surface of the locking component 10. The surface of the handle 18 is covered with a non-slip rubber sleeve to improve the grip comfort during operation. In addition, the surface of the positioning post 19 is provided with multiple limiting holes 22. The limiting holes 22 are evenly distributed along the axial direction of the positioning post 19 and can be used with the pin to temporarily fix the positioning post 19, which facilitates device maintenance or material cleaning in the unlocked state.
[0028] Please refer to Figure 1 and Figure 2The handle 11 on the top surface of the cylinder cover 5 has a U-shaped structure, and tempered glass 12 is embedded in the top surface of the cylinder cover 5. A threaded ring 6 is welded to the bottom of the cylinder cover 5. The outer surface of the opening on the top surface of the crushing cylinder 2 is provided with external threads corresponding to the threaded ring 6. Handhold parts 13 are welded to both sides of the handle 11. The handle 11 on the top surface of the cylinder cover 5 adopts an integrally formed U-shaped structure with a diameter of 25mm and an overall height of 10cm, which is convenient for operators to grip and apply force. Cylindrical handhold parts 13 are welded to both sides of the handle 11. The surface of the handhold parts 13 is knurled to increase friction and prevent hand slippage during operation. A 5mm thick tempered glass 12 is embedded in the top surface of the cylinder cover 5. The tempered glass 12 is explosion-proof and has a light transmittance of over 90%. Operators can observe the crushing situation inside the crushing cylinder 2 in real time through the tempered glass 12 and adjust the crushing time in a timely manner. The bottom of the cylinder cover 5 is welded with an annular threaded ring 6. The inner surface of the threaded ring 6 is machined with precision threads. The outer surface of the opening on the top surface of the crushing cylinder 2 is provided with matching external threads corresponding to the threaded ring 6. The thread accuracy reaches 6g level, ensuring a sealed connection between the cylinder cover 5 and the crushing cylinder 2, and effectively preventing dust generated during the crushing process from leaking out.
[0029] Please refer to Figure 1 and Figure 2 A support bracket 8 is welded to the middle of the side of the frame 1. The support bracket 8 consists of a vertical part and an inclined part, with the inclined part corresponding to the crushing cylinder 2. The support bracket 8 is welded from square steel and has an overall load-bearing capacity of not less than 50 kg. The support bracket consists of a vertical part and an inclined part. The vertical part is perpendicularly connected to the frame 1 and is 30 cm long. The angle between the inclined part and the vertical part is 135°, and the end of the inclined part bends upward to form an arc-shaped support surface, the curvature of which matches the outer arc of the crushing cylinder 2. When the crushing cylinder 2 rotates to the inclined discharge position, the inclined part can fit tightly against the outer surface of the crushing cylinder 2, providing additional support for the crushing cylinder 2, preventing the locking component 10 from deforming due to long-term stress, and extending the service life of the device.
[0030] Please refer to Figure 1 and Figure 2 A control switch 4 is fixedly installed on the left side wall of the frame 1, and the output terminal of the control switch 4 is electrically connected to the motor 3. The control switch 4 adopts a waterproof and dustproof design, and its surface has clearly marked buttons, including a start button, a stop button, and a speed adjustment knob. The internal circuit of the control switch 4 adopts an overload protection design, which can automatically cut off the power supply when the motor 3 experiences an abnormal overload to prevent the motor from burning out. The output terminal of the control switch 4 is electrically connected to the motor 3 through a high-temperature resistant cable, and the cable is protected by a metal corrugated tube to prevent wear during device operation.
[0031] Please refer to Figure 4One side of the support ring 20 is in contact with the inner wall of the locking component 10, and the other side of the support ring 20 is against one end of the spring 21. The other end of the spring 21 is against the inner wall of the locking component 10. With this installation method, the spring 21 is always in a slightly compressed state, which can generate a continuous thrust on the support ring 20, thereby driving the positioning column 19 to maintain pressure in the direction of the perforated positioning block 9, ensuring that the insertion and engagement between the positioning column 19 and the perforated positioning block 9 is stable and reliable, and effectively preventing the crushing cylinder 2 from accidentally shifting during the tilting discharge process.
[0032] Working Principle: First, connect the power cord of control switch 4 to an external power source. During the crushing operation, the operator seals and fixes the cylinder cover 5 onto the crushing cylinder 2 by engaging the threaded ring 6 on the top of the cylinder cover 5 with the external thread on the top surface of the crushing cylinder 2, ensuring that the material does not splash during the crushing process. Then, start motor 3 through control switch 4. The output of motor 3 drives the main crushing blade 14 and the auxiliary crushing blade 15 to rotate at high speed. The arc-shaped blade of the main crushing blade 14 first cuts and tears the input Chinese medicinal materials, while the sharp blade 16 penetrates deep into the interior of fibrous medicinal materials to crush them and prevent them from tangling. The blunt blade of the auxiliary crushing blade 15 then performs secondary grinding on the initially crushed material, making the medicinal material particles finer and more uniform. The operator can observe the crushing situation inside the crushing cylinder 2 through the tempered glass 12 until the expected effect is achieved. When it is time to discharge the material, turn off motor 3 and hold handle 11 to unscrew the cylinder cover 5. Then, pull the handle 18 of locking component 10 to compress spring 21 and disengage from perforated positioning block 9, thus releasing the lock on crushing cylinder 2. The grinding cylinder 2 is rotated around the rotating column 7 to an inclined position, and the grinding cylinder 2 contacts the inclined part of the support 8, which provides support for the grinding cylinder 2. The ground material can slide out along the inclined inner wall of the grinding cylinder 2 and fall into the designated collection container. The whole process achieves efficient grinding and reliable discharge of Chinese medicinal materials through the coordinated operation of the mechanical structure.
