Description

Technical Field

[0001] This utility model belongs to the field of traditional Chinese medicine decoction piece processing technology, specifically a traditional Chinese medicine decoction piece crushing device with screening function. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces are finished products in various forms, such as slices, segments, and blocks, made from raw medicinal materials through cleaning, cutting, and processing. They can be directly used in clinical formulations or pharmaceutical preparations. Crushing increases the specific surface area of ​​the decoction pieces, improving the dissolution efficiency of active ingredients and facilitating subsequent extraction and decoction. It also standardizes particle size, making it easier to mix, package, and store, reducing losses during transportation. Therefore, crushing is necessary for various TCM processing scenarios.

[0003] In the existing technology, crushing devices usually do not have the function of screening crushed particles, which leads to uneven particle size and affects the stability of dissolution of effective ingredients. Particles with excessively large particle size do not achieve the expected crushing effect and have insufficient specific surface area, while particles with excessively small particle size are prone to "over-crushing" and the effective ingredients are difficult to fully dissolve.

[0004] Therefore, this utility model provides a crushing device for Chinese herbal medicine slices with screening function. Utility Model Content

[0005] To address the shortcomings of existing technologies and solve the problem that crushing devices typically lack the function of screening crushed particles, resulting in uneven particle size, affecting the stability of active ingredient dissolution, and causing particles that are too large to achieve the expected crushing effect due to insufficient specific surface area, while particles that are too small are prone to "over-crushing," making it difficult for active ingredients to dissolve fully.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A traditional Chinese medicine decoction piece crushing device with screening function, comprising a shell, wherein a preparation mechanism is arranged inside the shell, and the preparation mechanism includes:

[0007] Crushing assembly, housed within the casing, is used for crushing.

[0008] The screening assembly includes a set of discharge holes on the housing. A screening plate is rotatably connected between the discharge holes and the hole walls via a first rotating shaft. A pair of rectangular blocks are fixed to the end of the screening plate away from the discharge holes. An isosceles hole is provided on the rectangular blocks. The housing is provided with a lifting assembly for driving the rectangular blocks to rise and fall.

[0009] A conveying assembly, mounted on the housing, is used to convey materials.

[0010] Preferably, the crushing assembly includes a pair of second rotating shafts rotatably connected between opposite sidewalls of the housing, with both ends of the second rotating shafts penetrating both sides of the housing, and crushing rollers fixedly connected to the second rotating shafts.

[0011] Preferably, a first motor is fixedly connected to the side wall of the housing via an L-shaped rod. The output end of the first motor is drivenly connected to one end of a second rotating shaft. A gear is fixedly connected to the second rotating shaft, and a pair of gears mesh with each other.

[0012] Preferably, the lifting assembly includes a sliding hole on the side wall of the housing, a set of sliding blocks slidably connected in the sliding hole, movable blocks fixed on both sides of the sliding blocks, the movable blocks being movably connected in the isosceles hole, and a rectangular plate fixed to the side wall of the set of sliding blocks.

[0013] Preferably, a support block is fixed to the side wall of the rectangular plate, and a support rod is rotatably connected to the support block through a rotating hole. A connecting rod is rotatably connected to both ends of the support rod. A disk is fixed to both ends of the second rotating shaft, and a circular block is fixed to the side wall of the disk. The end of the connecting rod away from the support rod is rotatably connected to the circular block through a rotating hole.

[0014] Preferably, the conveying assembly includes a fixed shell fixed to the side wall of the housing, and the bottom of the fixed shell is inclined. A fixed pipe is fixedly connected to the top of the fixed shell, and a conveying pipe is fixedly connected to the fixed pipe. The conveying pipe is inclined toward the top of the housing.

The output end of the second motor is provided with a rotating rod, and the bottom of the rotating rod is rotatably connected to the top of the fixed pipe and penetrates the inner top wall of the fixed pipe. An auger is fixedly connected to the rotating rod.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The present invention discloses a traditional Chinese medicine decoction piece crushing device with screening function. By setting a set of screening plates to swing up and down around a first rotating shaft as the fulcrum, dynamic screening can be performed, which can screen decoction pieces of different particle sizes separately and transport and collect them from the discharge hole. This solves the problem that in the prior art, crushing devices usually do not have the function of screening crushed particles, resulting in uneven particle size, affecting the stability of dissolution of effective ingredients, and particles with too large a particle size do not achieve the expected crushing effect due to insufficient specific surface area, while particles with too small a particle size are prone to "over-crushing" and the effective ingredients are difficult to fully dissolve.

[0017] 2. The Chinese herbal medicine crushing device with screening function described in this utility model, through the reciprocating oscillation of the screening plate, can drive the Chinese herbal medicine particles on the screen surface to continuously bounce up and down and move laterally, causing the material to continuously roll and change position. In this process, the particles originally accumulated on the surface will gradually contact the screen holes, avoiding material compaction in a single area; at the same time, fine particles can pass through the screen holes more quickly, while larger particles are fully lifted, effectively reducing the clogging problem caused by particles stuck in the screen holes, greatly improving the screening volume and screening accuracy per unit time, and ensuring continuous and smooth screening operation.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 4As shown in the figure, a traditional Chinese medicine decoction piece crushing device with screening function according to an embodiment of the present invention includes a housing 1, and a preparation mechanism is provided inside the housing 1. The preparation mechanism includes: a crushing component, which is provided inside the housing 1 for crushing; a screening component, which includes a set of discharge holes 2 opened on the housing 1, a screening plate 3 rotatably connected between the discharge holes 2 and the hole walls of the discharge holes 2 through a first rotating shaft, a pair of rectangular blocks 4 fixedly connected to one end of the screening plate 3 away from the discharge holes 2, and isosceles holes 5 opened on the rectangular blocks 4. A lifting component is provided on the housing 1 for driving the rectangular blocks 4 to rise and fall; and a conveying component, which is provided on the housing 1 for conveying materials.

[0026] The crushing assembly includes a pair of second rotating shafts 6 rotatably connected between opposite side walls of the housing 1, with the two ends of the second rotating shafts 6 passing through both sides of the housing 1 respectively, and crushing rollers 7 fixedly connected to the second rotating shafts 6.

[0027] A first motor 8 is fixedly connected to the side wall of the housing 1 by an L-shaped rod. The output end of the first motor 8 is driven and connected to one end of the second rotating shaft 6. A gear 9 is fixedly connected to the second rotating shaft 6, and a pair of gears 9 mesh with each other.

[0028] During operation, a set of screening plates 3, oscillating up and down around the first rotating shaft, dynamically screens different particle sizes of medicinal slices. The slices are then conveyed and collected from the discharge hole 2. This solves the problem in existing technologies where crushing devices typically lack the function of screening crushed particles, resulting in uneven particle size, affecting the stability of effective ingredient dissolution, insufficient specific surface area for oversized particles, and over-crushing of undersized particles, making it difficult for effective ingredients to dissolve fully.

[0029] The lifting assembly includes a housing 1 with a sliding hole 10 on the side wall. A set of sliding blocks 11 are slidably connected in the sliding hole 10. Movable blocks 12 are fixed on both sides of the sliding blocks 11. The movable blocks 12 are movably connected in the isosceles hole 5. A rectangular plate 13 is fixed on the side wall of the set of sliding blocks 11.

[0030] A support block 14 is fixedly attached to the side wall of the rectangular plate 13. The support block 14 is rotatably connected to a support rod 15 through a rotating hole. Both ends of the support rod 15 are rotatably connected to a connecting rod 16. Both ends of the second rotating shaft 6 are fixedly attached to a disc 17. A circular block 18 is fixedly attached to the side wall of the disc 17. The end of the connecting rod 16 away from the support rod 15 is rotatably connected to the circular block 18 through a rotating hole.

[0031] During operation, the reciprocating oscillation of the screening plate 3 causes the Chinese medicine granules on the screen surface to continuously bounce up and down and shift laterally, causing the material to tumble and change position. In this process, the granules that were originally piled up on the surface will gradually come into contact with the screen holes, avoiding compaction of material in a single area; at the same time, fine particles can pass through the screen holes more quickly, while larger particles are fully lifted up, effectively reducing the clogging problem caused by particles stuck in the screen holes, greatly improving the screening volume and screening accuracy per unit time, and ensuring continuous and smooth screening operation.

[0032] The conveying assembly includes a fixed shell 19 fixed to the side wall of the housing 1, and the bottom of the fixed shell 19 is inclined. A fixed pipe 20 is fixedly connected to the top of the fixed shell 19. A conveying pipe 21 is fixedly connected to the fixed pipe 20 and is inclined toward the top of the housing 1. A second motor 22 is fixedly connected to the top of the fixed pipe 20 through a fixed block. The output end of the second motor 22 is provided with a rotating rod 23, and the bottom of the rotating rod 23 is rotatably connected to the top of the fixed pipe 20 and passes through the inner top wall of the fixed pipe 20. An auger 24 is fixedly connected to the rotating rod 23.

[0033] During operation, the material is fed through the discharge hole 2 at the top of the fixed shell 19 to receive the Chinese medicine particles that are too large in size from the screening component. The large particles after screening are sent back to the crushing component to ensure that the material is crushed sufficiently, improve the finished product qualification rate, and avoid waste of raw materials.

[0034] Working Principle: After the device is started, the first motor 8, fixed to the side wall of the housing 1 via an L-shaped rod, outputs power to directly drive one of the second rotating shafts 6 to rotate. Since the gears 9 fixed to the two second rotating shafts 6 mesh with each other, when one second rotating shaft 6 rotates, it drives the other second rotating shaft 6 to rotate synchronously in the opposite direction through the meshing relationship of the gears 9. Both second rotating shafts 6 are fixed with crushing rollers 7. As the second rotating shafts 6 rotate synchronously in the opposite direction, the two crushing rollers 7 form a "relatively meshing" motion state. The Chinese medicinal herbs to be processed (such as root and leaf herbs) enter the housing 1 through the feed inlet and fall between the two crushing rollers 7. They are then crushed into smaller particles by the opposing rotating crushing rollers 7 through compression and shearing, completing the crushing process.

[0035] When the first motor 8 drives the second rotating shaft 6 to rotate, the discs 17 fixed at both ends of the second rotating shaft 6 rotate synchronously. The circular blocks 18 on the side wall of the discs 17 move in a circular motion with the discs 17. Through the rotational connection, the connecting rod 16 moves. The other end of the connecting rod 16 is rotatably connected to the support rod 15, converting the circular motion into the swing motion of the support rod 15. The support rod 15 is connected to the rectangular plate 13 through the support block 14, driving the rectangular plate 13 to reciprocate up and down. The sliding block 11 on the side wall of the rectangular plate 13 slides up and down in the sliding hole 10 of the housing 1. The movable blocks 12 on both sides of the sliding block 11 are embedded in the isosceles hole 5 of the rectangular block 4. When the sliding block 11 rises and falls, the movable block 12 slides in the isosceles hole 5 and pushes the rectangular block 4 to move up and down. Since one end of the screening plate 3 is rotatably connected to the housing 1 through the first rotating shaft, the rising and falling motion of the rectangular block 4 causes the screening plate 3 to swing back and forth around the first rotating shaft.

[0036] The discharge hole 2 at the top of the fixed shell 19 receives the Chinese medicine particles with excessively large particle size screened out by the screening component. After the second motor 22 at the top of the fixed tube 20 is started, its output end drives the rotating rod 23 to rotate. The bottom of the rotating rod 23 is stably supported on the top of the fixed tube 20 by the bearing structure. The auger 24 fixed on the rotating rod 23 rotates synchronously with the rotating rod 23. The material entering the fixed tube 20 is conveyed upward by the thrust of the spiral blades.
