Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine technology, specifically to an adaptive cutting device and method for the roots and stems of traditional Chinese medicine. Background Technology

[0002] With social development and improved living standards, people are paying more and more attention to their health. Health care, wellness, and medical treatment all require various medicinal materials, so the demand for medicinal materials is increasing. However, most Chinese medicinal materials are long and thin, so they need to be cut into slices when processing them.

[0003] However, due to the varying diameters of Chinese medicinal herbs, existing technologies typically employ clamping plates that work in conjunction with springs to hold the herbs. However, this method suffers from several drawbacks. For herbs with larger diameters, the clamping force is excessive, easily causing damage. For herbs with smaller diameters, the clamping force is insufficient, making it difficult to provide adequate clamping force. Consequently, the material cannot be fully compressed, resulting in some smaller-diameter herbs curling up during the cutting process. This leads to uneven thickness in the cut herbs, affecting both the efficiency and quality of the cutting process. Summary of the Invention

[0004] To address the problems existing in the prior art, an adaptive cutting device and cutting method for Chinese medicinal rhizomes are provided.

[0006] Preferably, the movable seat is further fixedly connected to a vertically arranged fixed rod, the fixed rod is slidably connected to a slider, the movable seat is rotatably connected to a vertically arranged screw, the slider and the screw are threadedly connected, and the screw is further connected to a second spiral spring for resetting; the elastic force of the second spring is greater than the elastic force of the first spring.

[0007] Preferably, the movable seat is rotatably connected to a first gear and a third gear, the movable seat is slidably connected to a small slider, the small slider is rotatably connected to a second gear, and the two ends of the second gear mesh with the first gear and the third gear respectively; the cutter is fixedly connected to a rack, and the first gear meshes with the rack.

[0008] Preferably, the screw is fixedly sleeved with a second disc gear and a first disc gear, and the third gear is coaxially connected with a fourth disc gear, the fourth disc gear meshing with the first disc gear.

[0009] Preferably, the double-helix screw is fixedly sleeved with a third disc gear, which meshes with the second disc gear. When the double-helix screw rotates, it drives the left and right clamping blocks to move towards or away from each other.

[0010] Preferably, the slider is slidably connected to an upper pressure block and a sliding rod that move in a vertical direction. The upper pressure block drives the sliding rod to move through a gear set, and the sliding rod is connected to the slider through a third spring.

[0011] Preferably, the slide bar is fixedly connected to a first inclined block and a second inclined block, the first inclined block is disposed on one side of the small slider, and the frame is also fixedly connected to a fixed inclined block, which is disposed on the other side of the small slider.

[0012] Preferably, the movable seat is fixedly connected to a guide rail, and the guide rail is slidably connected to a locking block for limiting the rotation of the third gear. One end of the locking block is fixedly connected to a first stop bar, and the other end of the locking block is fixedly connected to a second stop bar.

[0013] Preferably, the first stop bar is disposed on one side of the second inclined block, and the cutter is also fixedly connected to a third inclined block, with the second stop bar disposed on one side of the third inclined block.

[0014] This invention also proposes a cutting method using the aforementioned adaptive cutting device for Chinese medicinal rhizomes, comprising the following steps: S1: The conveying mechanism transports the medicinal materials to the fixed seat. Depending on the required length of the medicinal materials to be cut, the conveying speed of the conveying mechanism is controlled. Then, the cylinder is activated, and the cylinder drives the moving plate to move downward. The moving plate drives the moving seat to move downward through the second spring. At this time, the first spring is compressed. S2: As the moving seat continues to move downward, when the left clamp and right clamp contact the fixed seat, the moving seat and the first gear can no longer move downward. As the cutter continues to move downward, the second spring is compressed. The cutter drives the first gear to rotate through the rack. The first gear drives the screw to rotate in sequence through the second gear, the third gear, the fourth disc gear and the first disc gear. S3: When the screw rotates, it drives the double-helix screw to rotate through the second and third disc gears. The double-helix screw drives the left and right clamping blocks to move inward, thereby clamping the medicinal materials. At the same time, the screw drives the slider to move downward. When the upper pressure block comes into contact with the medicinal material, the upper pressure block can no longer move downward. As the slider continues to move downward, the upper pressure block drives the slide bar to move upward through the gear set. The slide bar drives the first inclined block and the second inclined block to move upward. S4: The first inclined block pushes the small slider to move. The small slider moves to the top of the fixed inclined block, so that the first gear and the third gear disengage from the second gear. At the same time, the second inclined block pushes the first stop to move. The first stop drives the locking block and the second stop to move. At this time, the locking block is engaged in the third gear, realizing the locking of the third gear. The second stop moves to the top of the third inclined block. S5: As the cutter continues to move downward, the medicinal material is cut. Then the cylinder drives the moving plate to reset. As the cutter moves upward, the cutter drives the second stop lever to move through the third inclined block. The second stop lever drives the locking block and the first stop lever to reset, so that the locking block no longer limits the rotation of the third gear. The first spiral spring resets the double-rotating screw, and the left and right clamps no longer hold the medicinal materials. The second spiral spring resets the screw, the third spring resets the slide bar, and the second and first springs reset the moving seat. Then, as the moving seat rises, when the rack moves above the first gear, the small slider moves to the side of the fixed wedge block. The fixed wedge block drives the small slider to reset, so that the second gear re-engages with the first and third gears.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This application features an upper pressure block. The height of the upper pressure block varies depending on the diameter of the medicinal herb, thus affecting the rotation time of the double-rotating screw. The larger the diameter of the medicinal herb, the shorter the rotation time of the double-rotating screw, and the further apart the left and right clamping blocks become. This allows for clamping medicinal herbs of different diameters with good clamping force. During reset, the cutter moves above the medicinal herb first to complete the cutting, and then the double-rotating screw resets, preventing the herb from being carried away by the cutter after cutting. This improves clamping efficiency, is easy to operate, and is suitable for automatic clamping of medicinal herbs of different diameters. It facilitates the cutting of medicinal herbs and effectively reduces issues such as the herb sticking up during cutting, thus preventing uneven cut thickness.

[0016] This application is equipped with a sliding rod. When the upper pressure block moves, it can drive the sliding rod to move. The sliding rod can drive the second gear to move through the first inclined block. At this time, the movement of the cutter will no longer drive the third gear to rotate. At the same time, the sliding rod can drive the locking block to engage between the teeth of the third gear, thereby locking the third gear and preventing it from rotating. During the reset, the above structure can be reset under the action of the spring and the inclined block, which facilitates the next cutting operation. The structure is ingenious and can realize the automatic clamping of Chinese medicinal materials and the automatic release of clamping, which is convenient for clamping Chinese medicinal materials and for cutting Chinese medicinal materials.

Detailed Implementation

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] like Figure 1-7 As shown in the figure, this embodiment proposes an adaptive cutting device for Chinese medicinal roots and stems, including a frame 1. The frame 1 is fixedly connected to a fixed seat 5 for placing medicinal materials. A conveying mechanism is provided on one side of the fixed seat 5. The conveying mechanism can be a conveyor belt or other structure. The conveying mechanism is used for conveying Chinese medicinal materials. When the cutting speed is constant, by controlling different conveying speeds of the conveying mechanism, it is easy to achieve the cutting of Chinese medicinal materials to different lengths.

[0021] The frame 1 is fixedly connected to a vertically arranged sliding shaft 9. Several sliding shafts 9 can be provided, and the sliding shafts 9 are arranged in parallel. The sliding shaft 9 is slidably connected to a movable plate 3 and a movable seat 4. The sliding shaft 9 plays a role in limiting and guiding the movement of the movable plate 3 and the movable seat 4.

[0022] The upper end of the movable seat 4 is connected to the movable plate 3 via the second spring 10, and the lower end of the movable seat 4 is connected to the frame 1 via the first spring 7. Both the second spring 10 and the first spring 7 are sleeved on the sliding shaft 9. The upper end of the second spring 10 is connected to the lower end of the movable plate 3, and the lower end of the second spring 10 is connected to the upper end of the movable seat 4. The upper end of the first spring 7 is connected to the upper end of the movable seat 4, and the lower end of the first spring 7 is connected to the frame 1. The first spring 7 and the second spring 10 cooperate with each other to realize the reset operation of the movable seat 4.

[0023] The movable plate 3 is fixedly connected to a vertically oriented cutter 6, which can also be slidably connected to the frame 1. The cutter 6 can only slide in the vertical direction to achieve the cutting of Chinese medicinal materials. The frame 1 is also connected to a cylinder 2, the lower end of which is connected to the upper end of the movable plate 3. When the cylinder 2 is working, it can drive the movable plate 3 to reciprocate vertically.

[0024] The movable seat 4 is rotatably connected to a horizontally arranged double-rotating lead screw 30. The two ends of the double-rotating lead screw 30 are fitted with a left clamping block 29 and a right clamping block 33. The double-rotating lead screw 30 is also connected to a first spiral spring for resetting. The left clamping block 29 and the right clamping block 33 are slidably connected to the movable seat 4, and the movable seat 4 can only slide in the vertical direction and will not rotate.

[0025] One end of the first spiral spring is connected to the double-rotating lead screw 30, and the other end of the first spiral spring is connected to the movable seat 4. The first spiral spring is used for the reset of the double-rotating lead screw 30. When the double-rotating lead screw 30 rotates, it drives the left clamping block 29 and the right clamping block 33 to move towards or away from each other. In the initial state, under the action of the first spiral spring, there is a sufficient distance between the left clamping block 29 and the right clamping block 33, which facilitates the clamping of Chinese medicinal materials.

[0026] The bottom of the movable base 4 is also fixedly connected to a vertically arranged fixed rod 28. The movable base 4 is also slidably connected to a vertically moving slide rod 14. The fixed rod 28 is slidably connected to a slider 13. The slide rod 14 and the slider 13 are slidably connected. The slider 13 can only slide in the vertical direction.

[0027] The movable seat 4 is rotatably connected to a vertically arranged screw 27. The slider 13 is threadedly connected to the screw 27. The screw 27 is also connected to a second spiral spring for resetting. When the screw 27 rotates, it can drive the movable seat 4 to reciprocate vertically. One end of the second spiral spring is connected to the screw 27, and the other end of the second spiral spring is connected to the movable seat 4. The second spiral spring is used for the resetting of the screw 27.

[0028] The movable seat 4 is rotatably connected to the first gear 16 and the third gear 18. The movable seat 4 is slidably connected to the small slider, and the small slider is rotatably connected to the second gear 17. The two ends of the second gear 17 are respectively engaged with the first gear 16 and the third gear 18. The small slider slides along the horizontal direction of the movable seat 4. When the small slider moves, it can drive the second gear 17 to move. At this time, the first gear 16 and the third gear 18 are disengaged from the second gear 17.

[0029] The cutter 6 is fixedly connected to the rack 8. The first gear 16 meshes with the rack 8. When the cutter 6 moves downward, it can drive the first gear 16 to rotate through the rack 8, thereby driving the third gear 18 to rotate through the second gear 17.

[0030] The elastic force of the second spring 10 is much greater than that of the first spring 7. Therefore, when the cutter 6 descends, the first spring 7 is compressed. At this time, under the action of the second spring 10, the cutter 6 and the moving seat 4 move downwards simultaneously. Therefore, the rack 8 will not drive the first gear 16 to rotate. When the left clamping block 29 and the right clamping block 33 come into contact with the fixed seat 5, the moving seat 4 cannot continue to move downwards. When the cutter 6 continues to descend, the rack 8 can drive the first gear 16 to rotate.

[0031] The screw 27 is fixedly sleeved with the second disc gear 24 and the first disc gear 19. The third gear 18 is coaxially connected to the fourth disc gear 32. The fourth disc gear 32 and the first disc gear 19 mesh with each other. When the third gear 18 rotates, it can drive the fourth disc gear 32 to rotate. The fourth disc gear 32 can drive the screw 27 to rotate through the first disc gear 19.

[0032] The double-helix screw 30 is fixedly fitted with a third disc gear 26, and the movable seat 4 is also rotatably connected with a double-headed bevel gear 25. One end of the double-headed bevel gear 25 meshes with the third disc gear 26, and the other end of the double-headed bevel gear 25 meshes with the second disc gear 24. Therefore, when the screw 27 rotates, the second disc gear 24 can drive the third disc gear 26 to rotate through the double-headed bevel gear 25, thereby driving the double-helix screw 30 to rotate.

[0033] The slider 13 is slidably connected to the vertically moving upper pressure block 12 and the slide rod 14. The upper pressure block 12 drives the slide rod 14 to move via a gear set. The slide rod 14 is connected to the slider 13 via a third spring 11. The third spring 11 is sleeved on the slide rod 14. The upper end of the third spring 11 is connected to the slider 13, and the lower end of the third spring 11 is connected to the slide rod 14. The third spring 11 is used for the reset function of the slide rod 14.

[0034] The gear set includes several meshing gears. The gears on both sides mesh with the upper pressure block 12 and the slide rod 14 respectively. Therefore, when the upper pressure block 12 moves upward, the slide rod 14 can be driven to move upward through the gear set.

[0035] The slide bar 14 is fixedly connected to a first inclined block 15 and a second inclined block 23. The first inclined block 15 is located on one side of the small slider. The frame 1 is also fixedly connected to a fixed inclined block 31, which is located on the other side of the small slider.

[0036] When the slide bar 14 moves upward, it can drive the first inclined block 15 to move upward. The first inclined block 15 can drive the small slider to move horizontally, so that the second gear 17 disengages from the first gear 16 and the third gear 18. At this time, the small slider will move to the side of the fixed inclined block 31. Therefore, when the moving seat 4 moves upward to reset, it will drive the small slider to reset under the action of the fixed inclined block 31, so that the second gear 17 re-engages with the first gear 16 and the third gear 18.

[0037] The movable seat 4 is fixedly connected to a guide rail 35, which is set in a horizontal direction. The guide rail 35 is slidably connected to a locking block 21 for limiting the rotation of the third gear 18. The guide rail 35 limits and guides the movement of the locking block 21.

[0038] One end of the locking block 21 is fixedly connected to a first stop bar 20, and the other end of the locking block 21 is fixedly connected to a second stop bar 22. The first stop bar 20 is located on one side of the second inclined block 23, and the cutter 6 is also fixedly connected to a third inclined block 34, with the second stop bar 22 located on one side of the third inclined block 34.

[0039] When the slide bar 14 moves upward, it can drive the second inclined block 23 to rise. The second inclined block 23 can drive the first stop bar 20 to move horizontally. The first stop bar 20 drives the locking block 21 and the second stop bar 22 to move. The locking block 21 is engaged between the third gear 18, which can lock the third gear 18.

[0040] Meanwhile, the second stop lever 22 will move above the third inclined block 34. Therefore, when the cutter 6 moves upward, it can drive the third inclined block 34 to move. The third inclined block 34 can push the second stop lever 22 to move, thereby resetting the locking block 21 and disengaging the locking block 21 from the third gear 18.

[0041] In the initial state, since the second stop lever 22 is located on one side of the third inclined block 34, the second stop lever 22 will not affect the normal movement of the third inclined block 34. Only when the locking block 21 locks the third gear 18 will the second stop lever 22 move above the third inclined block 34. When the third gear 18 is locked, the screw 27 can be prevented from reversing.

[0042] A cutting method, employing the aforementioned adaptive cutting device for Chinese medicinal rhizomes, includes the following steps: S1: The conveying mechanism transports the medicinal materials to the fixed seat 5. Depending on the required length of the medicinal materials to be cut, the conveying mechanism controls different conveying speeds. Then, the cylinder 2 is activated, and the cylinder 2 drives the moving plate 3 to move downward. The moving plate 3 drives the moving seat 4 to move downward through the second spring 10. At this time, the first spring 7 is compressed. S2: As the movable seat 4 continues to move downward, when the left clamping block 29 and the right clamping block 33 come into contact with the fixed seat 5, the movable seat 4 and the first gear 16 can no longer move downward. As the cutter 6 continues to move downward, the second spring 10 is compressed. The cutter 6 drives the first gear 16 to rotate through the rack 8. The first gear 16 drives the screw 27 to rotate in sequence through the second gear 17, the third gear 18, the fourth disc gear 32 and the first disc gear 19. S3: When the screw 27 rotates, it drives the double-helix screw 30 to rotate through the second disc gear 24 and the third disc gear 26. The double-helix screw 30 drives the left clamping block 29 and the right clamping block 33 to move inward, thereby clamping the medicinal material. At the same time, the screw 27 drives the slider 13 to move downward. When the upper pressure block 12 comes into contact with the medicinal material, the upper pressure block 12 can no longer move downward. As the slider 13 continues to move downward, the upper pressure block 12 drives the slide bar 14 to move upward through the gear set. The slide bar 14 drives the first inclined block 15 and the second inclined block 23 to move upward. S4: The first inclined block 15 pushes the small slider to move, and the small slider moves above the fixed inclined block 31, so that the first gear 16 and the third gear 18 are disengaged from the second gear 17. At the same time, the second inclined block 23 pushes the first stop 20 to move, and the first stop 20 drives the locking block 21 and the second stop 22 to move. At this time, the locking block 21 is locked into the third gear 18, and the third gear 18 is locked. The second stop 22 moves above the third inclined block 34. S5: As the cutter 6 continues to move downward, the medicinal material is cut. Then, the cylinder 2 drives the moving plate 3 to reset. As the cutter 6 moves upward, the cutter 6 drives the second stop 22 to move through the third inclined block 34. The second stop 22 drives the locking block 21 and the first stop 20 to reset, so that the locking block 21 no longer limits the rotation of the third gear 18. The first spiral spring resets the double-rotating screw 30, and the left clamp 29 and right clamp 33 no longer clamp the medicinal material. The second spiral spring resets the screw 27. The third spring 11 resets the slide bar 14. The second spring 10 and the first spring 7 reset the movable seat 4. Then, as the moving seat 4 rises, when the rack 8 moves above the first gear 16, the small slider moves to the side of the fixed inclined block 31. The fixed inclined block 31 drives the small slider to reset, so that the second gear 17 re-meshes with the first gear 16 and the third gear 18.

[0043] It should be noted that the height of the upper pressure block 12 varies depending on the diameter of the Chinese medicinal material, thus affecting the rotation time of the double-rotating screw 30. The larger the diameter of the Chinese medicinal material, the shorter the rotation time of the double-rotating screw 30, and the further apart the left clamping block 29 and right clamping block 33 become. Therefore, it can clamp Chinese medicinal materials of different diameters and has a good clamping force for Chinese medicinal materials of different diameters. During the reset, the cutter 6 can move above the Chinese medicinal material first to complete the cutting, and then the double-rotating screw 30 resets. This prevents the Chinese medicinal material from being carried away by the cutter 6 after cutting, improves clamping efficiency, and is easy to operate. It is suitable for automatic clamping of Chinese medicinal materials of different diameters, facilitates the cutting of Chinese medicinal materials, and effectively reduces the occurrence of uneven cutting thickness caused by the tip of the medicinal material sticking up during the cutting process.

[0044] In addition, when the upper pressure block 12 moves, it can drive the slide rod 14 to move. The slide rod 14 can drive the second gear 17 to move through the first inclined block 15. At this time, the movement of the cutter 6 will no longer drive the third gear 18 to rotate. At the same time, the slide rod 14 can drive the locking block 21 to engage between the teeth of the third gear 18, thereby locking the third gear 18 and preventing it from rotating. During the reset, under the action of the spring and the inclined block, the above structure can be reset, which is convenient for the next cutting operation. The structure is ingenious and can realize the automatic clamping of Chinese medicinal materials and the automatic release of clamping, which is convenient for clamping Chinese medicinal materials and for cutting Chinese medicinal materials.

[0045] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.

Depending on the required length of the medicinal materials to be cut, the conveying mechanism controls different conveying speeds. Then, the cylinder (2) is started. The cylinder (2) drives the moving plate (3) to move downward. The moving plate (3) drives the moving seat (4) to move downward through the second spring (10). At this time, the first spring (7) is compressed. S2: As the moving seat (4) continues to move downward, when the left clamp (29) and the right clamp (33) come into contact with the fixed seat (5), the moving seat (4) and the first gear (16) can no longer move downward. As the cutter (6) continues to move downward, the second spring (10) is compressed. The cutter (6) drives the first gear (16) to rotate through the rack (8). The first gear (16) drives the screw (27) to rotate in sequence through the second gear (17), the third gear (18), the fourth disc gear (32) and the first disc gear (19). S3: When the screw (27) rotates, the double-helix screw (30) is driven to rotate through the second disc gear (24) and the third disc gear (26). The double-helix screw (30) drives the left clamping block (29) and the right clamping block (33) to move inward to clamp the medicinal material. At the same time, the screw (27) drives the slider (13) to move downward. When the upper pressure block (12) comes into contact with the medicinal material, the upper pressure block (12) can no longer move downward. As the slider (13) continues to move downward, the upper pressure block (12) drives the slide bar (14) to move upward through the gear set. The slide bar (14) drives the first inclined block (15) and the second inclined block (23) to move upward. S4: The first inclined block (15) pushes the small slider to move. The small slider moves above the fixed inclined block (31), so that the first gear (16) and the third gear (18) disengage from the second gear (17). At the same time, the second inclined block (23) pushes the first stop (20) to move. The first stop (20) drives the locking block (21) and the second stop (22) to move. At this time, the locking block (21) is locked into the third gear (18), thus locking the third gear (18). The second stop (22) moves above the third inclined block (34). S5: As the cutter (6) continues to move downward, the medicinal material is cut. Then the cylinder (2) drives the moving plate (3) to reset. As the cutter (6) moves upward, the cutter (6) drives the second stop (22) to move through the third inclined block (34). The second stop (22) drives the locking block (21) and the first stop (20) to reset, so that the locking block (21) no longer limits the rotation of the third gear (18). The first spiral spring resets the double-rotating screw (30), and the left clamp (29) and right clamp (33) no longer clamp the medicinal material. The second spiral spring resets the screw (27), the third spring (11) resets the slide (14), and the second spring (10) and the first spring (7) reset the moving seat (4). Then, as the moving seat (4) rises, when the rack (8) moves above the first gear (16), the small slider moves to the side of the fixed inclined block (31), and the fixed inclined block (31) drives the small slider to reset, so that the second gear (17) re-meshes with the first gear (16) and the third gear (18).
