Description

Technical Field

[0001] This invention relates to the field of equipment technology for processing Chinese medicinal materials, specifically a pulverizing device for processing Chinese medicinal materials. Background Technology

[0002] Traditional Chinese medicinal herbs are the core material basis of the traditional Chinese medicine system. They refer to natural medicines and their processed products used for the prevention, treatment, diagnosis, and rehabilitation of diseases under the guidance of traditional Chinese medicine theory. Originating from traditional Chinese medical practice, they are the crystallization of wisdom and key raw materials for the research and development of modern Chinese medicine preparations, compound prescriptions, and innovative drugs.

[0003] Currently, there are tens of thousands of kinds of Chinese medicinal materials. Different Chinese medicinal materials have different characteristics. For example, common Chinese medicinal materials such as ginseng, wolfberry, and rehmannia have extremely high sugar content. During the pulverization and pharmaceutical manufacturing process, due to their high sugar content, they are prone to forming a gel-like adhesion layer on the cavity wall, resulting in drug residue and affecting the subsequent processing of other medicinal materials. For example, common Chinese medicinal materials such as astragalus, kudzu root, and codonopsis are rich in fiber and starch. During the pulverization process, they are prone to producing fine powder, resulting in a large amount of dust remaining in the equipment cavity, requiring routine cleaning by staff and increasing their workload.

[0004] To address the dust and adhesion issues that arise during the pulverization of various Chinese medicinal herbs, existing technologies, such as the self-contained residue cleaning structure of a Chinese medicinal herb processing device (application number 202310117007.0), utilize a vibrating cleaning component inside the device. This component vibrates during the processing to dislodge residues from the inner wall of the equipment. However, because herbs with high sugar content, such as goji berries and ginseng, tend to stick to the equipment during pulverization, vibration alone is less effective for drier raw materials. Therefore, existing technologies still have many problems in practical applications. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a pulverizing device for processing Chinese medicinal materials, which solves the problems mentioned in the background section.

The outer edge of the first grinding disc is provided with horizontally open clamping pieces, and each clamping piece is equipped with a rotatable pulley. The pulleys extend into the slot, and the first grinding disc rotates in the slot through the pulleys.

[0009] Preferably, the first grinding disc has a plurality of first mounting grooves arranged in a circumferential array on its surface, extending from the center of the first grinding disc to its outer edge. Each mounting groove has a mounting box at both ends, and each mounting box contains a torsion spring. A rotatable grinding roller is installed between two corresponding torsion springs. The grinding roller has a semi-circular cross-section and a plurality of raised first grinding blocks are provided on its arc-shaped surface. The grinding roller is also sealed at the opening of the first mounting groove.

[0010] Preferably, a buffer airbag is provided at the center of the upper end face of the first crushing disc, which is sealed and surrounds the outside of the main shaft, and a first spring is provided inside the buffer airbag, which is also surrounded by the outside of the main shaft.

[0011] Preferably, a second spring surrounds the outside of the telescopic rod, the pressure plate is a circular umbrella-shaped structure with the central plate surface raised upwards, and multiple second mounting grooves extending from the center of the pressure plate to its outer edge are opened on the surface of the pressure plate. A rotatable cleaning roller is installed in the second mounting groove, a gap is left between the center of the pressure plate and the main shaft, and a brush is provided on the cleaning roller.

[0012] Preferably, the exhaust port has an annular structure, and a rotatable exhaust fan is installed at the lower end of the middle plate of the exhaust port, with the lower end of the exhaust fan sleeved on the main shaft.

[0013] Preferably, the second crushing disc has the same circular umbrella-shaped structure as the first crushing disc, with a gap between the second crushing disc and the first crushing disc. The second crushing disc has multiple third mounting grooves extending from the center of the second crushing disc to its outer edge. A rotatable grinding roller is installed in the third mounting groove. The upper arc surface of the grinding roller abuts against the bottom of the first crushing disc. A discharge port is opened on the side wall of the casing between the second crushing disc and the first crushing disc. A cleaning brush extending towards the tube sleeve is provided on one side of the inner wall of the discharge port.

[0014] Preferably, a gear box is mounted inside the housing cavity and positioned below the second crushing disc. The gear box has inwardly extending bevel gears rotatably mounted on both sides. The main shaft and the sleeve both extend into the gear box. A first gear disk is mounted on a section of the sleeve placed on the gear box, and a second gear disk is mounted on a section of the main shaft placed on the gear box. The first and second gear disks are arranged opposite to each other, and both the first and second gear disks are meshed with the bevel gears and move in opposite directions on the same axis.

[0015] Preferably, a drive motor is coaxially connected to the lower end of the main shaft.

[0016] Beneficial effects This invention provides a pulverizing device for processing Chinese medicinal materials, which has the following beneficial effects: This equipment, by setting up a pressing component, allows the raw materials of Chinese medicine to be crushed to be fed into the pressing plate and the first crushing plate through the feed inlet. The pressing plate, supported by the elastic force of the second spring, pushes the pressing plate downward to press down the material. This solves the problems of splashing and uneven crushing of Chinese medicine materials of different sizes and weights during the crushing process. At the same time, the pressing plate is equipped with a cleaning roller, which can contact the surface of the first crushing plate during the rotation of the first crushing plate to clean the adhering Chinese medicine materials.

[0017] A rotatable grinding roller is installed on the first grinding disc. During its rotation, the first grinding disc rubs against the Chinese medicinal materials, thereby actuating the grinding roller. The grinding roller rubs against the Chinese medicinal materials, thus pulverizing them. During the rotation of the grinding roller, the grinding roller opens the cover of the first mounting groove, allowing the qualified fragments to enter between the first and second grinding discs for further grinding. At the same time, torsion springs are set at both ends of the grinding roller. The spring force pulls the grinding roller back to its original position and can actuate the Chinese medicinal materials to change position during the reset process to continue pulverizing, thereby improving the pulverizing efficiency. The main shaft and the sleeve move in opposite directions on the same axis, which can further refine and pulverize the fragments passing through the first mounting groove to meet the pulverization requirements.

[0018] Furthermore, an exhaust fan is also installed at the upper end of the main shaft. A dust collection bag can be connected to the outer end of the exhaust fan. The dust swept by the cleaning roller enters the upper end of the pressing plate and can be collected into the dust collection bag during the exhaust process of the exhaust fan.

[0019] This equipment uses a single power source to drive the main shaft, enabling not only multi-stage grinding but also various self-cleaning functions tailored to the characteristics of different Chinese herbal raw materials. For example, the rotation of the first grinding disc causes the cleaning roller to rotate passively to clean the surface, while the main shaft simultaneously drives the exhaust fan to expel dust. By using a single power source to drive multiple stages of action simultaneously, it is more energy-efficient and effective than multiple independent units working independently. Furthermore, it collects the dust and debris released from the Chinese herbal materials, making it more environmentally friendly. Attached Figure Description

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] Example 1: The pulverizing device for processing Chinese medicinal materials disclosed in this invention is mainly used to solve the problems of splashing, insufficient pulverization, material adhesion, and dust residue that exist when pulverizing Chinese medicinal materials with different characteristics, such as ginseng and wolfberry with high sugar content, and astragalus and kudzu root rich in fiber and starch, during the pulverization process. Through the cooperation of various components, the device achieves efficient and clean pulverization of Chinese medicinal materials. The specific implementation structure and working process are as follows: like Figure 2 As shown, the device as a whole includes a chassis 1, which is a hollow cylindrical structure with an open top. An annular exhaust port 103 is opened at the top of the chassis 1, and a docking port 104 is fixedly arranged around the top of the exhaust port 103. The docking port 104 is used to connect a dust collection bag or other dust collection equipment to achieve centralized dust collection. The exhaust assembly, the pressing assembly, and the crushing assembly are assembled in sequence from top to bottom inside the chassis 1.

[0026] like Figure 3 As shown, the pressing assembly is used to achieve stable downward pressure on the material, preventing material splashing during the crushing process, and simultaneously cleaning the material adhering to the surface of the first crushing disc 4. The pressing assembly consists of telescopic rods 8, a second spring 901, and a pressing disc 5. Multiple telescopic rods 8 are fixedly mounted on the upper surface of the housing 1, all extending downwards. The preferred number of telescopic rods 8 is 4-6, arranged in a circumferential array along the housing 1 to ensure uniform force distribution on the pressing disc 5. A second spring 901 is sleeved around the outer side of each telescopic rod 8. The upper end of the second spring 901 abuts against the upper surface of the housing 1, and the lower end abuts against the upper surface of the pressing disc 5, providing a continuous and stable elastic downward pressure to the pressing disc 5, preventing material splashing due to insufficient pressure or material inconsistency.

[0027] like Figure 2 , 3As shown, a pressing plate 5 is suspended at the lower end of the telescopic rod 8. The pressing plate 5 is a circular umbrella-shaped structure with the central plate surface raised upwards, which is adapted to the structure of the first crushing plate 4 to ensure that the material can be evenly distributed between the pressing plate 5 and the first crushing plate 4. Multiple second mounting grooves 501 extending from the center to the outer edge are opened on the surface of the pressing plate 5. A cleaning roller 502 is rotatably mounted in each second mounting groove 501 via a rotating shaft. A brush is fixedly installed on the surface of the cleaning roller 502. When the lower end of the brush is pressed down to its lowest point, due to the support of the buffer airbag 9, a small gap is left between it and the first crushing plate 4 to avoid direct contact and wear. It also slightly abuts against the upper surface of the first crushing plate 4, ensuring that when the first crushing plate 4 rotates, the cleaning roller 502 can simultaneously contact its surface and be driven by the rotation of the first crushing plate 4, effectively cleaning the Chinese medicinal materials adhering to the first crushing plate 4 and preventing material residue.

[0028] like Figure 1 , 2 As shown, a feed inlet 101 is opened on the outer wall of the chamber 1. The feed inlet 101 is located between the pressing plate 5 and the first crushing plate 4, which facilitates the feeding of the Chinese medicine raw materials to be crushed into the two. A movable cover plate can be installed at the feed inlet 101, which can be closed when not in use to prevent dust from escaping or materials from splashing during the crushing process.

[0029] like Figure 2 , 4 As shown, the crushing component is the core crushing part of the device, used to achieve graded crushing of materials and ensure that the crushing fineness meets the standard. The crushing component includes a main shaft 2, a sleeve 3, a first crushing disc 4, a second crushing disc 6, a gear box 7, and a drive motor 202. The main shaft 2 is rotatably installed between the top and bottom of the machine box 1. The drive motor 202 is coaxially fixedly connected to the lower end of the main shaft 2. The drive motor 202 is a servo motor, which can adjust the speed according to the material characteristics to provide power for the entire crushing process. The upper end of the main shaft 2 is fixedly connected to the exhaust component to realize the linkage between the exhaust component and the main shaft 2.

[0030] The housing 1 has a protruding slot 105 circumferentially arranged in the center of the cavity. The slot 105 is an annular groove structure. The first crushing disc 4 is rotatably slidably embedded in the slot 105 to ensure stable operation of the first crushing disc 4. The first crushing disc 4 is a circular umbrella-shaped structure with the central plate surface raised upwards, which is adapted to the pressing disc 5. The outer edge of the disc is evenly provided with horizontally open clamping plates 404. Each clamping plate 404 is equipped with a rotatable pulley 405, which extends into the slot 105. The first crushing disc 4 rotates in the slot 105 through the pulleys 405, effectively reducing friction during rotation and improving operational stability.

[0031] like Figure 4As shown, the first grinding disc 4 has multiple first mounting grooves 401 arranged in a circumferential array on its surface, extending from its center outwards. Each mounting groove 401 has a mounting box 402 fixedly installed at both ends. Each mounting box 402 contains a torsion spring, and a rotatable grinding roller 403 is installed between two corresponding torsion springs. The grinding roller 403 has a semi-circular cross-section, with multiple raised first grinding blocks on its arc-shaped surface. Normally, the grinding roller 403 seals the opening of the first mounting groove 401. When the torsion spring is in its natural state, it pulls the grinding roller 403 to fit against the opening of the first mounting groove 401, achieving a seal. When the first grinding disc 4 rotates and rubs against the medicinal materials, it can rotate the grinding roller 403 around its axis, opening the opening of the first mounting groove 401. Simultaneously, the grinding roller 403 rubs against the medicinal materials, achieving preliminary grinding of the material, corresponding to the grinding and material screening functions of the grinding roller 403 in the beneficial effects.

[0032] like Figure 2 As shown, a sleeve 3 is fitted around the outside of the main shaft 2. The sleeve 3 can rotate relative to the main shaft 2. A second crushing disc 6 is fixedly installed on the top of the sleeve 3. The second crushing disc 6 is placed below the first crushing disc 4, and a suitable gap is left between them for further grinding the crushed material falling through the first mounting groove 401. The second crushing disc 6 has the same circular umbrella-shaped structure as the first crushing disc 4. Multiple third mounting grooves 601 are opened on its plate surface, extending from its center to its outer edge. A rotatable grinding roller 602 is installed in the third mounting groove 601. The upper arc surface of the grinding roller 602 abuts against the bottom of the first crushing disc 4 to ensure that the falling crushed material is fully ground and finely ground.

[0033] A gear box 7 is mounted inside the housing 1, positioned below the second crushing disc 6. Two inwardly extending bevel gears 701 are rotatably mounted on both sides of the gear box 7. The main shaft 2 and the sleeve 3 both extend into the gear box 7. A first gear disc 301 is mounted on one section of the sleeve 3 within the gear box 7, and a second gear disc 201 is mounted on one section of the main shaft 2 within the gear box 7. The first and second gear discs 301 are positioned opposite each other and are both meshed with the bevel gears 701. When the drive motor 202 drives the main shaft 2 to rotate, the main shaft 2 drives the first gear disc 301 to rotate via the second gear disc 201 and the bevel gears 701. This, in turn, causes the sleeve 3 to move coaxially and in the opposite direction to the main shaft 2, resulting in the first crushing disc 4 and the second crushing disc 6 rotating in opposite directions. This further refines and crushes the material, ensuring that the pulverization requirements are met.

[0034] like Figure 4As shown, in addition, a buffer airbag 9 is provided in the middle of the upper end face of the first crushing disc 4, which is sealed and surrounds the outside of the main shaft 2. A first spring 801 is provided in the buffer airbag 9, which is surrounded by the outside of the main shaft 2, to buffer the damage caused by the direct contact between the pressing disc 5 and the first crushing disc 4 during the pressing process. A discharge port 102 is opened on the side wall of the machine box 1 between the second crushing disc 6 and the first crushing disc 4. The crushed qualified material is discharged through the discharge port 102. A cleaning brush 111 extending towards the sleeve 3 is provided on one side of the inner wall of the discharge port 102. During the rotation of the first crushing disc 4 and the second crushing disc 6, it is used to clean the residual material on the surface of the second crushing disc 6, further reducing material residue.

[0035] The exhaust assembly is used to centrally collect dust and solve the problem of dust residue. The exhaust assembly is rotatably mounted on the upper port of the casing 1, including an exhaust fan 203, the aforementioned telescopic rod 8, and the pressure plate 5. The exhaust port 103 has an annular structure, with a rotatable exhaust fan 203 installed at the lower end of the central panel of the exhaust port 103. The lower end of the exhaust fan 203 is sleeved and mounted on the main shaft 2, and is linked to the main shaft 2. When the main shaft 2 rotates, it synchronously drives the exhaust fan 203. A dust collection bag is connected to the outer end of the exhaust fan 203 through a docking port 104. The cleaning roller 502 sweeps away the dust generated on the surface of the first crushing disc 4, as well as the fine powder generated during the crushing process. This dust is carried by the cleaning roller 502 and dispersed to the upper end of the pressure plate 5 during rotation. Under the exhaust action of the exhaust fan 203, the dust enters the dust collection bag through the annular exhaust port 103 and the docking port 104, achieving centralized dust collection, preventing dust residue in the equipment cavity, reducing the cleaning burden on workers, and corresponding to the beneficial effect of dust collection.

[0036] Example 2: The working process of this device specifically addresses the problems of material splashing, insufficient crushing, adhesion, and dust residue in the background technology. The specific steps are as follows: First, securely connect the docking port 104 at the upper end of the exhaust vent 103 to the dust collection bag. Then, start the drive motor 202. The drive motor 202 drives the main shaft 2 to rotate. The main shaft 2, through the meshing transmission of the bevel gear 701, the first gear disk 301, and the second gear disk 201 in the gear box 7, drives the sleeve 3 to rotate coaxially and in the opposite direction with the main shaft 2, thereby driving the first crushing disk 4 and the second crushing disk 6 to rotate in the opposite direction. At the same time, the main shaft 2 drives the exhaust fan 203 to operate synchronously, forming a slight negative pressure in the casing 1 to prepare for dust collection.

[0037] The medicinal materials to be pulverized are fed into the pressure plate 5 and the first pulverizing plate 4 through the feed inlet 101. Supported by the elastic force of the second spring 901, the pressure plate 5 applies stable downward pressure, firmly pressing the material onto the first pulverizing plate 4. This prevents the material from splashing during pulverization due to the rotation of the first pulverizing plate 4, while ensuring that materials of different sizes and weights can fully contact the first pulverizing plate 4. This solves the problems of insufficient pulverization and the inability of the pulverizing component to function properly when the medicinal materials are small.

[0038] Driven by the main shaft 2, the first grinding disc 4 rotates continuously, and its surface rubs against the Chinese medicinal materials. The friction force drives the grinding roller 403 to rotate around the shaft. The first grinding blocks on the arc-shaped surface of the grinding roller 403 fully rub and collide with the Chinese medicinal materials, achieving initial grinding of the materials. During the rotation of the grinding roller 403, its obstruction of the first mounting groove 401 is opened. At this time, the qualified-sized fragments can fall through the first mounting groove 401 into the space between the first grinding disc 4 and the second grinding disc 6 for further grinding; while the unqualified materials will remain on the surface of the first grinding disc 4 and be further ground by the grinding roller 403. At the same time, the torsion springs at both ends of the grinding roller 403 deform when the grinding roller 403 rotates. When the material is ground to a certain size and the friction force decreases, the elastic force of the torsion spring pulls the grinding roller 403 to reset. During the reset process, the residual Chinese medicinal materials will be moved to change position, ensuring that the material can be fully and uniformly ground, effectively improving the grinding efficiency.

[0039] Since the main shaft 2 and the sleeve 3 move in opposite directions on the same axis, the first crushing disc 4 and the second crushing disc 6 rotate in opposite directions. The crushed material falling between them will be further refined and crushed by the grinding action between the bottom of the first crushing disc 4 and the grinding roller 602, ensuring that the crushed material meets the preset pulverization requirements and meets the needs of subsequent traditional Chinese medicine preparations and processing.

[0040] During the crushing process, a certain amount of dust is generated. Simultaneously, as the first crushing disc 4 rotates, the cleaning roller 502 continuously contacts its surface, sweeping away the material adhering to the surface. The dust generated during sweeping is dispersed to the upper end of the pressing disc 5 as the cleaning roller 502 rotates. Due to the continuous operation of the exhaust fan 203, the resulting negative pressure draws this dust into the annular exhaust port 103, and then through the docking port 104 into the external dust collection bag, achieving centralized dust collection, preventing dust residue in the equipment cavity, and reducing the cleaning burden on staff.

[0041] The material, after secondary fine crushing and reaching the required pulverization level, falls between the second crushing disc 6 and the side wall of the machine casing 1 under the action of gravity and the centrifugal force of the rotation of the first and second crushing discs 6, and is finally discharged through the discharge port 102, completing the crushing process. After processing, the drive motor 202 is turned off, and the dust collection bag is removed for dust cleaning to avoid cross-contamination during the processing of different Chinese medicinal materials.

[0042] This equipment uses a single power source to drive the main shaft 2, enabling not only multi-stage grinding but also various self-cleaning functions tailored to the characteristics of different Chinese herbal raw materials. For example, the rotation of the first grinding disc 4 causes the cleaning roller 502 to rotate passively to clean its surface, while the main shaft 2 simultaneously drives the exhaust fan 203 to expel dust. By using a single power source to drive multiple stages of action simultaneously, it is more energy-efficient and efficient than the independent operation of multiple independent units. Furthermore, it collects the dust and debris released from the Chinese herbal materials, making it more environmentally friendly.

[0043] The foregoing has shown and described the basic principles and main features of the present invention and its advantages. It will be apparent to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects.

Therefore, it is intended that all changes falling within the meaning and scope of the equivalents of the claims be included within the present invention, and no reference numerals in the claims should be regarded as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
