Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine decoction piece processing technology, and in particular to a pulverizing and mixing device for traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces refer to TCM herbs that have undergone processing according to specific needs, either for prescription or for direct use in TCM clinical practice. TCM decoction pieces represent the essence of TCM; different processing methods alter the medicinal properties and efficacy of the herbs, which is a characteristic and advantage of TCM.

[0003] The patent application with publication number CN118437489A discloses a high-efficiency pulverizer for processing Chinese herbal medicine slices. Through the cooperation between the crushing mechanism and the grinding mechanism, it is convenient to replace manual labor for fine grinding of Chinese herbal medicine slices. It solves the problem in the prior art that the operator drives the grinding disc to move back and forth in the medicine mill, which is time-consuming and laborious and reduces the grinding efficiency of Chinese herbal medicine slices.

[0004] However, when Chinese medicinal herbs are ground in a grinding tank by the reciprocating motion of the grinding blocks, some powders that have reached the qualified particle size will be over-ground. At the same time, the heat generated by friction during grinding can easily cause the loss of nutrients in the medicinal materials. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a pulverizing and mixing device for Chinese herbal medicine slices that can effectively avoid excessive grinding of Chinese herbal medicine particles and reduce the loss of nutrients in the medicinal materials during the grinding process.

[0006] The technical solution is as follows: A pulverizing and mixing device for Chinese herbal medicine slices includes multiple support legs, with a stirring chamber fixedly connected to the top of the multiple support legs. Multiple grinding chambers are provided on the top of the stirring chamber, and the multiple grinding chambers are arranged in a line. Each grinding chamber has a pair of crushing rollers rotatably connected inside. A first drive assembly is provided on the grinding chamber to drive all the crushing rollers to rotate together. A feeding chamber is provided on the top of the grinding chamber, and the bottom of the feeding chamber is connected to the top of the grinding chamber through a feeding channel. The lower part of the grinding chamber penetrates the top of the stirring chamber and has multiple sieve holes. A grinding plate is rotatably provided inside the grinding chamber. A second drive assembly is provided on the grinding chamber. The second drive assembly is used to drive the grinding plate to rotate periodically along the inner sidewall of the grinding chamber. One side of the grinding plate is in contact with the inner sidewall of the grinding chamber, and the other side of the grinding plate is connected to a lifting plate. The lifting plate and the grinding plate form a hook shape for capturing Chinese herbal medicine particles. Two cooling plates are provided inside the grinding chamber, and the two cooling plates are arranged in an inverted octagon above the two crushing rollers.

[0007] Furthermore, the side of the grinding plate that is in contact with the inner wall of the grinding chamber has multiple grinding strips, and the inner wall of the grinding chamber has striped grooves that match the grinding strips.

[0008] Furthermore, the grinding plate and the lifting plate are rotatably connected by a rotating shaft. A torsion spring is connected to the rotating shaft between the grinding plate and the lifting plate. A protrusion is connected to the lifting plate. The protrusion is used to cooperate with the inner side wall of the grinding chamber to achieve the formation of the hook shape.

[0009] Furthermore, the first drive assembly includes a drive shaft and a motor. Two drive shafts are rotatably connected in the middle of multiple grinding chambers. The two crushing rollers of each grinding chamber are detachably connected to the two drive shafts. The motor is installed on the left side of the leftmost grinding chamber. The output shaft of the motor is driven by one of the drive shafts. One end of the two drive shafts is driven by a gear assembly.

[0010] Furthermore, the second drive assembly includes a rotating ring and a second motor. The rotating ring is rotatably connected inside the grinding chamber. There are multiple grinding plates, and the multiple grinding plates are connected to the rotating ring. A small gear is rotatably provided inside the grinding chamber. A gear ring that meshes with the small gear is provided on the inner side of the rotating ring. The second motor is installed on the outer wall of the grinding chamber, and the output shaft of the second motor is connected to the small gear for transmission.

[0011] Furthermore, a cooling box is provided on the front side of the mixing chamber, and the cooling plate is connected to the cooling box by a cooling pipe.

[0012] Furthermore, a distribution cylinder is horizontally rotatably connected inside the feeding hopper, and at least two quantitative grooves are opened on the distribution cylinder. A motor is installed on the front side of the feeding hopper, and the output shaft of the motor is connected to the distribution cylinder for transmission. A feed port is opened on the top of the feeding hopper.

[0013] Furthermore, a stirring rod is horizontally rotatably connected inside the mixing chamber, and a motor is installed on the left side of the mixing chamber. The output shaft of the motor is connected to the stirring rod for transmission. A discharge port is opened at the bottom of the mixing chamber, and a sealing plate is rotatably connected to the discharge port.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention, through the hook-shaped design of the grinding plate and the lifting plate, periodically captures and releases medicinal powder particles during the grinding process, effectively avoiding over-grinding of powder that has reached the required particle size, thus improving the output quality and efficiency of medicinal powder. At the same time, through the guiding design of the cooling plate for the medicinal powder particles, the temperature of the medicinal powder particles during the grinding process can be effectively reduced, reducing the loss of medicinal nutrients caused by frictional heat generation, and ensuring the quality and efficacy of the medicinal powder.

[0028] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0029] Please see Figures 1-8 A pulverizing and mixing device for traditional Chinese medicine decoction pieces includes four support legs. A mixing chamber 1 is fixedly connected to the top of each of the four support legs. Four grinding chambers 2 are arranged in a line on top of the mixing chamber 1 to process different types of traditional Chinese medicine decoction pieces. Each grinding chamber 2 has a pair of crushing rollers 4 rotatably connected inside for preliminary crushing of the traditional Chinese medicine decoction pieces entering the grinding chamber 2. A first driving assembly is provided on each grinding chamber 2 to drive all the crushing rollers 4 to rotate synchronously. Each grinding chamber 2 has a feeding chamber 3 on top, with a feeding channel at the bottom. 15 is connected to the top of the grinding chamber 2. The lower part of the grinding chamber 2 penetrates the top of the mixing chamber 1 and has multiple sieve holes 201. These sieve holes 201 allow powder particles that have reached the qualified particle size after crushing and grinding to fall into the mixing chamber 1. A grinding plate 5 is rotatably installed inside the grinding chamber 2. A second drive assembly is provided on the grinding chamber 2. The second drive assembly is used to drive the grinding plate 5 to rotate periodically along the inner wall of the grinding chamber 2. One side of the grinding plate 5 is in close contact with the inner wall of the grinding chamber 2, and the other side of the grinding plate 5 is connected to a lifting plate 6. The grinding plate 5 and the lifting plate 6 are connected by a... A rotating shaft is connected, and two torsion springs 601 are installed on the shaft. A protrusion 602 is connected to the lifting plate 6. When the grinding plate 5 is not in contact with the lower opening of the feed channel 15 on the inner wall of the grinding chamber 2, the protrusion 602 contacts the inner wall of the grinding chamber 2, causing the lifting plate 6 to rotate to form a hook shape with the grinding plate 5 that can capture Chinese medicine particles. The torsion springs 601 deform. When the grinding plate 5 rotates to the inner top of the grinding chamber 2, that is, below the lower opening of the feed channel 15, the protrusion 602 disengages from the inner wall of the grinding chamber 2. When the grinding plate 6 is lifted by the hook shape formed by the lifting plate 6 and the grinding plate 5, it will rotate under the elastic action of the torsion spring 601 and no longer form a hook shape with the grinding plate 5. At this time, the captured Chinese medicine particles will fall naturally. The grinding chamber 2 is equipped with two cooling plates 9, which are arranged in an inverted octagon shape above the two crushing rollers 4. When the Chinese medicine particles released after being lifted by the hook shape formed by the lifting plate 6 and the grinding plate 5 fall naturally, the two cooling plates 9 can guide the Chinese medicine particles to contact and reduce the temperature of the Chinese medicine particles during the contact process, thereby reducing the loss of medicinal nutrients caused by frictional heat generation.

[0030] The grinding plate 5 has multiple grinding strips 501 on the side that is in contact with the inner wall of the grinding chamber 2. The inner wall of the grinding chamber 2 has striped grooves 202 that match the grinding strips 501. When the grinding plate 5 rotates, the grinding strips 501 move along the trajectory of the striped grooves 202, repeatedly squeezing and grinding the Chinese medicine particles that fall into the grinding chamber 2 until they reach the required fineness. When the powder reaches the required fineness, the gap between the grinding strips 501 and the striped grooves 202 gradually increases, so that the powder can fall smoothly from the sieve holes 201 of the grinding chamber 2, avoiding the decline in powder quality caused by over-grinding.

[0031] The first drive assembly includes a drive shaft 701 and a motor 702. Two drive shafts 701 are rotatably connected to the middle of multiple grinding chambers 2. The two crushing rollers 4 of each grinding chamber 2 are detachably connected to the two drive shafts 701. The motor 702 is installed on the left side of the leftmost grinding chamber 2. The output shaft of the motor 702 is connected to one of the drive shafts 701. One end of the two drive shafts 701 is connected to the gear assembly 703. Specifically, the gear assembly 703 includes two meshing large gears. When the motor 702 starts, its output shaft drives one of the drive shafts 701 to rotate. Since the two drive shafts 701 are connected through the gear assembly 703, the other drive shaft 701 will also rotate synchronously. In this way, the two crushing rollers of each grinding chamber can rotate simultaneously to perform preliminary crushing of the Chinese herbal medicine raw materials.

[0032] The second drive assembly includes a rotating ring 801 and a second motor 802. The rotating ring 801 is rotatably connected to the grinding chamber 2. There are two grinding plates 5, which are connected to the rotating ring 801. A small gear 803 is rotatably installed inside the grinding chamber 2. A gear ring 804 that meshes with the small gear 803 is provided on the inner side of the rotating ring 801. The second motor 802 is installed on the outer wall of the grinding chamber 2. The output shaft of the second motor 802 is connected to the small gear 803 for transmission. When it is necessary to grind the powder, the second motor 802 will start and drive the small gear 803 to rotate. The rotation of the small gear 803 drives the rotating ring 801 and the grinding plates 5 connected to it to rotate together through the gear ring 804.

[0033] A cooling box 901 is provided on the front side of the mixing chamber 1. The cooling plate 9 is connected to the cooling box 901 through a cooling pipe 902. The cooling plate 9 can be continuously cooled by the circulation of coolant in the cooling pipe 902 within the cooling box 901.

[0034] A dispensing cylinder 10 is horizontally rotatably connected inside the feeding hopper 3. The dispensing cylinder 10 has two metering slots 11 to facilitate the feeding of an appropriate amount of Chinese herbal medicine slices into the grinding hopper 2 each time. A motor 12 is installed on the front side of the feeding hopper 3. The output shaft of the motor 12 is connected to the dispensing cylinder 10 for transmission. The top of the feeding hopper 3 has a feed inlet. By controlling the motor 12 to drive the dispensing cylinder 10 to rotate, the quantitative addition of Chinese herbal medicine slices can be achieved.

[0035] A stirring rod 13 is horizontally rotatably connected inside the mixing chamber 1. A motor 14 is installed on the left side of the mixing chamber 1. The output shaft of the motor 14 is connected to the stirring rod 13. By controlling the motor 14 to drive the stirring rod 13 to rotate, the powder in the mixing chamber 1 can be stirred and mixed evenly. A discharge port is opened at the bottom of the mixing chamber 1, and a sealing plate 16 is rotatably connected to the discharge port.

[0036] Working principle: Initially, the protrusion 602 contacts the inner wall of the grinding chamber 2, causing the lifting plate 6 and the grinding plate 5 to form a hook shape. The torsion spring 601 deforms and stores elastic potential energy. The sealing plate 16 is in a closed state of the discharge port of the mixing chamber 1.

[0037] In use, different Chinese herbal raw materials are first fed into the corresponding feed bins 3 through different feed ports. Then, the distribution cylinder 10 is driven to rotate by the motor 3 12. The Chinese herbal raw materials are transferred by the two quantitative grooves 11 of the distribution cylinder 10, so that an appropriate amount of Chinese herbal raw materials fall into the corresponding grinding bins 2 below each time. Then, the crushing rollers 4 of all grinding bins 2 are driven to rotate by the first drive component to initially crush the Chinese herbal raw materials into Chinese herbal granules.

[0038] After initial crushing, the Chinese medicine granules fall into the bottom of the grinding chamber 2 under gravity. At this time, the grinding plate 5 is driven by the second drive component to rotate periodically along the inner wall of the grinding chamber 2. The grinding strips 501 on the grinding plate 5 interact with the striped grooves 202 on the inner wall of the grinding chamber 2 to finely grind the Chinese medicine granules. As the Chinese medicine granules are gradually ground into powder of qualified fineness, the powder can fall into the mixing chamber 1 through the sieve holes 201 on the grinding chamber 2.

[0039] During the grinding process, the hook-like shape formed between the grinding plate 5 and the lifting plate 6 can capture the Chinese herbal medicine particles located at the bottom of the grinding chamber 2. When the grinding plate 5 rotates to the top of the grinding chamber 2, the protrusion 602 disengages from the inner wall of the grinding chamber 2, and the lifting plate 6 rotates under the elastic action of the torsion spring 601, no longer forming a hook-like shape with the grinding plate 5. At this time, the lifted Chinese herbal medicine particles will fall naturally under their own gravity and, guided by the two cooling plates 9, will pass through the two crushing rollers 4 and fall into the bottom of the grinding chamber 2. Subsequently, the grinding plate 5 continues to rotate... When the lifting plate 6 moves, the protrusion 602 on the lifting plate 6 re-contacts the inner wall of the grinding chamber 2, applying pressure to the lifting plate 6 and causing it to rotate in the opposite direction to reset. In this way, through the continuous rotation of the grinding plate 5, the Chinese medicine granules undergo multiple grinding, lifting and falling processes in the grinding chamber 2 until they reach the qualified fineness and are sieved out through the sieve hole 201, ensuring the uniformity of the fineness of the final powder. At the same time, when the Chinese medicine granules come into contact with the two cooling plates 9 during the falling process, their temperature is reduced, thereby preventing the quality of the ground powder from being affected by frictional heat.

[0040] Finally, the powder produced in the multiple grinding chambers 2 falls into the mixing chamber 1. The stirring rod 13 is driven by the motor 14 to rotate continuously. The stirring rod 13 stirs the different types of powder to ensure that the various Chinese medicine ingredients can be mixed evenly. When it is necessary to take out the stirred powder, the powder can be discharged through the discharge port by opening the sealing plate 16.

[0041] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
