Description

Technical Field

[0001] This utility model relates to the technical field of Mongolian medicine processing equipment, and in particular to a medicinal material pulverizing device for granule production. Background Technology

[0002] In the production of granules, the crushing of medicinal materials is a crucial preliminary step that directly affects the quality and production efficiency of the granules. Currently, most medicinal material crushing devices on the market rely on the unidirectional rotation of the crushing shaft to achieve the crushing of medicinal materials.

[0003] In the production of Mongolian medicine granules, medicinal materials often contain a large amount of fibrous rhizomes (such as Astragalus membranaceus and Sophora flavescens), fleshy stems (such as Cynomorium songaricum), and fruits containing mucilage (such as Terminalia chebula). Traditional pulverizing devices, due to the unidirectional rotation of the pulverizing shaft, cause the medicinal materials (especially fiber bundles) to be subjected to shearing force in only one direction, which easily leads to problems such as "blade entanglement" and "incomplete pulverization". Taking the licorice rhizome, which is commonly used in Mongolian medicine, as an example, when pulverizing with traditional devices, the residual rate of fibrous components is as high as 15%, requiring multiple re-grinding, which not only reduces efficiency but may also lead to the loss of volatile components due to repeated pulverization. Utility Model Content

[0004] This invention provides a medicinal material pulverizing device for granule production, which solves the problem that in existing medicinal material pulverizing devices, the medicinal material can only be subjected to force in one direction when the pulverizing shaft rotates in one direction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A medicinal material pulverizing device for granule production includes a base, a pulverizing mechanism, and a feeding mechanism. Support frames are fixedly installed on both sides of the upper end of the base. The pulverizing mechanism includes a housing and several sets of shearing blades. The two sides of the housing are rotatably connected to two opposite surfaces of a pair of support frames. A pulverizing chamber is rotatably connected inside the housing. A rotating shaft is rotatably connected to the bottom of the pulverizing chamber. Several cutter discs are fitted onto the rotating shaft. Several pairs of pulverizing blades are arranged in a circular array inside the cutter discs. Each set of shearing blades is positioned between each pair of pulverizing blades. The outer side of each set of shearing blades is fixedly connected to the inner wall of the pulverizing chamber. Connecting blocks are installed on both sides of the upper end of the housing. The feeding mechanism includes a cover located at the upper end of the housing. A feeding pipe is inserted into the center of the cover.

[0007] Furthermore, the crushing mechanism also includes a sleeve rod, the top end of which is connected to the center of the bottom end of the crushing box, and a connecting shaft is rotatably connected inside the sleeve rod.

[0008] Furthermore, the top end of the connecting shaft is connected to the bottom end of the rotating shaft, and the bottom end of the connecting shaft is rotatably connected to the bottom end of the inner cavity of the housing.

[0009] Furthermore, a first bevel gear is fitted at the bottom end of the sleeve rod, and a second bevel gear is fitted at the bottom end of the connecting shaft.

[0010] Furthermore, a speed reducer is fixedly installed on one side of the bottom of the housing, and a third bevel gear is sleeved on the output end of the speed reducer. The first bevel gear, the second bevel gear and the third bevel gear mesh with each other.

[0011] Furthermore, a first servo motor is fixedly installed on one side of the reducer, and the output end of the first servo motor is connected to the input end of the reducer.

[0012] Furthermore, the feeding mechanism also includes a feeding plate, which is inclined and its bottom side is connected to the top of the feeding pipe. A vibration motor is installed on the bottom side of the feeding plate.

[0013] Furthermore, fixing bolts are movably inserted on both sides of the upper end of the box cover, and the bottom end of the fixing bolts is threadedly connected to the center of the connecting block.

[0014] Furthermore, a second servo motor is fixedly installed on one side of the upper end of the support frame, and the output end of the second servo motor is connected to the housing via transmission.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model's base provides stable support for the entire granule production herbal pulverizing device. The support frame is mounted on the base, providing support and a foundation for the pulverizing mechanism. The pulverizing mechanism's housing can rotate on the support frame, facilitating angle adjustment and discharging the pulverized herbal powder. The pulverizing housing rotates within the housing, with the rotating shaft driving the cutter disc and pulverizing blades. Addressing the characteristics of Mongolian medicinal herbs—high fiber toughness and easy entanglement—this device creates a 'bidirectional shearing field' through the opposing rotation of the pulverizing blades and shearing plates, effectively cutting the fiber bundles of herbs such as licorice and ephedra, avoiding the blade entanglement problem caused by traditional unidirectional pulverization. Actual measurements show that the one-time pulverization pass rate for fibrous Mongolian medicinal herbs is increased to over 92%. Furthermore, the housing can rotate and tilt during pulverization to discharge material, adapting to the 'low temperature, short-time pulverization' process requirements in Mongolian medicine production, reducing the loss of volatile components (such as patchouli oil). A connecting block connects to the feeding mechanism, whose cover is located at the top of the housing, and the feeding pipe facilitates the feeding of herbs into the pulverizing housing.

[0026] Example

[0027] Please see Figure 1-5 This utility model provides a medicinal material pulverizing device for granule production, including a base 1, a pulverizing mechanism 3, and a feeding mechanism 4. Support frames 2 are fixedly installed on both sides of the upper end of the base 1. The pulverizing mechanism 3 includes a housing 301 and several sets of shearing blades 305. The two sides of the housing 301 are rotatably connected to two opposite surfaces of a pair of support frames 2. A pulverizing chamber 302 is rotatably connected inside the housing 301. A rotating shaft 303 is rotatably connected to the bottom of the pulverizing chamber 302, and several blades are sleeved on the rotating shaft 303. The disc 314 has several pairs of crushing blades 304 inside, which are arranged in a ring array. Each set of shearing blades 305 is respectively arranged between each pair of crushing blades 304. The outer side of each set of shearing blades 305 is fixedly connected to the inner wall of the crushing box 302. Connecting blocks 306 are installed on both sides of the upper end of the box body 301. The feeding mechanism 4 includes a box cover 401, which is located at the upper end of the box body 301. A feeding pipe 405 is inserted at the center of the box cover 401. The base 1 provides stable support for the entire granule production herbal pulverizing device. The support frame 2 is installed on the base 1, providing support and a mounting foundation for the pulverizing mechanism 3. The housing 301 of the pulverizing mechanism 3 can rotate on the support frame 2, facilitating the adjustment of the angle of the housing 301 and the pouring out of the pulverized herbal powder inside. The pulverizing box 302 rotates inside the housing 301. The rotating shaft 303 drives the cutter disc 314 and the pulverizing blade 304 to rotate. The reverse rotation of the shearing blade 305 and the pulverizing blade 304 is achieved through a three-stage bevel gear transmission mechanism. Specifically, the power output of the first servo motor 313 is transmitted to the third bevel gear 311 via the reducer 312. The third bevel gear 311 simultaneously engages with the first bevel gear 308 at the bottom of the sleeve rod 307 and the second bevel gear 308 at the bottom of the connecting shaft 310. The bevel gears 309 mesh. Due to the meshing characteristics of the bevel gears, the first bevel gear 308 drives the sleeve rod 307 and the pulverizing box 302 connected thereto to rotate, causing the shearing blade 305 fixed on the inner wall of the pulverizing box 302 to rotate accordingly. The second bevel gear 309 drives the connecting shaft 310 and the rotating shaft 303 connected thereto to rotate, causing the pulverizing blade 304 on the cutter disc 314 on the rotating shaft 303 to rotate accordingly. Due to the meshing position and structural design of the first bevel gear 308, the second bevel gear 309 and the third bevel gear 311, the rotation direction of the pulverizing box 302 (shearing blade 305) and the rotating shaft 303 (pulverizing blade 304) is opposite, thus achieving reverse rotation of the two and forming a bidirectional shearing force in the pulverizing box 302 to efficiently pulverize the medicinal materials.

[0028] Since the shearing blades 305 and the pulverizing blades 304 rotate in opposite directions, and each set of shearing blades 305 is positioned between each pair of pulverizing blades 304, they generate shearing force when rotating in opposite directions, thus better pulverizing the medicinal materials in the pulverizing chamber 302. The connecting block 306 is used to connect the feeding mechanism 4. The cover 401 of the feeding mechanism 4 is located at the upper end of the chamber body 301, and the feeding pipe 405 facilitates the feeding of medicinal materials into the pulverizing chamber 302. In particular, the inner wall of the pulverizing chamber 302 is coated with a polytetrafluoroethylene anti-stick coating, which is suitable for Mongolian medicinal materials containing mucilage and oil (such as nutmeg and blue thorn), preventing material adhesion from affecting pulverizing efficiency. The included angle between the cutter disc 314 and the rotating shaft 303 is 30° to 90°, and the cutting angle of the pulverizing blades 304 can be adjusted according to the hardness of the Mongolian medicinal materials (such as the mineral medicine gypsum and the animal medicine musk shell).

[0029] The crushing mechanism 3 also includes a sleeve rod 307. The top end of the sleeve rod 307 is connected to the center of the bottom end of the crushing box 302. The sleeve rod 307 is rotatably connected to a connecting shaft 310. The sleeve rod 307 of the crushing mechanism 3 is connected to the center of the bottom end of the crushing box 302, and the connecting shaft 310 is rotatably connected inside. This structural design allows the crushing box 302 and the rotating shaft 303 to achieve relative rotation while ensuring the stability of the overall structure, providing support for rotation in different directions.

[0030] The top end of the connecting shaft 310 is connected to the bottom end of the rotating shaft 303, and the bottom end of the connecting shaft 310 is rotatably connected to the bottom end of the inner part of the housing 301. This connection ensures that the rotating shaft 303 can rotate stably within the housing 301, providing a stable power transmission path for the rotation of the crushing blade 304.

[0031] A first bevel gear 308 is fitted at the bottom end of the sleeve rod 307, and a second bevel gear 309 is fitted at the bottom end of the connecting shaft 310. The first bevel gear 308 at the bottom end of the sleeve rod 307 and the second bevel gear 309 at the bottom end of the connecting shaft 310, together with the subsequent third bevel gear 311, can realize the multi-directional transmission of power, so that the crushing box 302 and the rotating shaft 303 rotate in opposite directions.

[0032] A reducer 312 is fixedly installed on one side of the bottom of the housing 301. A third bevel gear 311 is sleeved on the output end of the reducer 312. The first bevel gear 308, the second bevel gear 309 and the third bevel gear 311 mesh with each other. The reducer 312 and the third bevel gear 311 on one side of the bottom of the housing 301 mesh with the first bevel gear 308 and the second bevel gear 309. The speed of the pulverizing box 302 and the pulverizing blade 304 can be controlled by the reducer 312. The speed can be adjusted according to the characteristics of different medicinal materials and pulverizing requirements to improve the pulverizing effect.

[0033] A first servo motor 313 is fixedly installed on one side of the reducer 312. The output end of the first servo motor 313 is connected to the input end of the reducer 312. The first servo motor 313 on one side of the reducer 312 provides power to the entire crushing mechanism 3. Its output end is connected to the input end of the reducer 312, which ensures the stability and reliability of the crushing process.

[0034] The feeding mechanism 4 also includes a feeding plate 402, which is inclined and connected to the top of the feeding pipe 405. A vibration motor 403 is installed on the bottom of the feeding plate 402. The feeding plate 402 of the feeding mechanism 4 is inclined and connected to the top of the feeding pipe 405. The vibration generated by the vibration motor 403 can make the medicinal materials pass through the feeding pipe 405 more smoothly into the crushing box 302 under the action of gravity and vibration, avoid the accumulation of medicinal materials, and improve the feeding efficiency.

[0035] Fixing bolts 404 are movably inserted on both sides of the upper end of the box cover 401. The bottom end of the fixing bolts 404 is threadedly connected to the center of the connecting block 306. The fixing bolts 404 on both sides of the upper end of the box cover 401 are threadedly connected to the center of the connecting block 306, so that the box cover 401 is firmly connected to the box body 301, preventing the box cover 401 from loosening during the crushing process and ensuring the safety and sealing of the crushing process.

[0036] A second servo motor 5 is fixedly installed on one side of the upper end of the support frame 2. The output end of the second servo motor 5 is connected to the housing 301 for transmission. The second servo motor 5 on one side of the upper end of the support frame 2 is connected to the housing 301 for transmission, which can control the housing 301 to rotate on the support frame 2, making it convenient to discharge the crushed medicinal materials and improving the ease of use of the device.

[0037] Specifically, the working principle of this granule production herbal pulverizing device is as follows: The base 1 provides stable support for the entire device, and the support frame 2 installed on it provides a support foundation for the pulverizing mechanism 3. The vibration motor 403 of the feeding mechanism 4 is started. Addressing the requirement in Mongolian medicine production that 'cleaned herbs need to be pulverized quickly,' after starting the vibration motor 403, the chopped Mongolian medicinal slices (such as soaked and softened licorice segments and shade-dried ephedra stems) can be evenly fed into the feeding pipe 405 through the inclined feeding plate 402, avoiding fiber tangling caused by manual feeding. After pulverization, the second servo motor 5 rotates the box 301 to a 45° tilt angle. Combined with the anti-stick coating on the inner wall of the pulverizing box 302, residue-free discharge of herbs containing viscous substances (such as Polygonatum sibiricum) can be achieved, meeting the Mongolian medicine quality standard of 'clean powder for medicinal use.' The cover 401 is threadedly connected to the connecting block 306 on the box body 301 by fixing bolts 404, ensuring the sealing and safety of the feeding process. The first servo motor 313 is started, and power is transmitted through the reducer 312, then through the third bevel gear 311 at the output end to the first bevel gear 308 and the second bevel gear 309. The first bevel gear 308 drives the sleeve rod 307 and the connected crushing box 302 to rotate, while the second bevel gear 309 drives the connecting shaft 310 and the connected rotating shaft 303 to rotate. Because the first bevel gear 308... The transmission relationship between the 8th and the second bevel gear 309 causes the pulverizing box 302 and the rotating shaft 303 to rotate in opposite directions. The cutter disc 314 and the pulverizing blade 304 on the rotating shaft 303 rotate accordingly, generating shearing force with the shearing blade 305 fixed on the inner wall of the pulverizing box 302, thus pulverizing the medicinal materials in the pulverizing box 302. After the medicinal materials are pulverized, the box cover 401 is opened, and the second servo motor 5 on one side of the upper end of the support frame 2 is started. Its output end drives the box body 301 to rotate on the support frame 2, and the pulverized medicinal powder is poured out from the box body 301, completing the discharge operation.

[0038] In particular, when processing mineral medicinal materials (such as gypsum and magnetite) in Mongolian medicine, the rotation speed of the crushing blade 304 can be adjusted to 1500-2000 r / min by the first servo motor 313, and with the fixed support of the shearing blade 305, the impact-shear composite crushing of hard materials can be achieved; when processing volatile medicinal materials (such as cloves and nutmeg), the rotation frequency of the box 301 can be controlled to 5-10 r / min to reduce the damage of the active ingredients caused by the heat generated during crushing.

[0039] In summary, this utility model sets the rotation directions of the shearing blade and the pulverizing blade to opposite directions, and each set of shearing blades is placed between each pair of pulverizing blades. When the two rotate in opposite directions, they can generate shearing force, which can better pulverize the medicinal materials in the pulverizing box.
