Description

Technical Field

[0001] This invention belongs to the field of traditional Chinese medicine processing machinery technology, and more specifically, it relates to a device for precisely slicing traditional Chinese medicine decoction pieces with adjustable thickness. Background Technology

[0002] Slicing Chinese medicinal herbs is one of the core processes in the processing of Chinese medicinal herbs. The quality of the slices directly affects the efficacy, storage stability, and subsequent application experience of the Chinese medicinal herbs. Currently, most of the mainstream Chinese medicinal herb slicing equipment in the industry uses belt conveyor combined with blade shearing to achieve processing. However, traditional equipment has many limitations in structural design and is difficult to fully adapt to the needs of large-scale and high-precision production. As a manufacturer specializing in the research and development and production of Chinese medicine processing equipment, we have discovered a core problem in our long-term service to Chinese medicine processing enterprises: existing slicing equipment cannot simultaneously solve the four core requirements of stable conveying, reliable fixing, adjustable thickness, and convenient maintenance. During material conveying, belt drive deviations can easily cause offsets, resulting in inconsistent slicing benchmarks. Fixing the material either involves hard compression that damages the medicinal materials or loose fixing that causes the slices to slip, affecting the uniformity of thickness. The slice thickness adjustment mechanism lacks flexibility and is difficult to quickly adapt to the production of multiple specifications of medicinal slices. Blade replacement requires special tools, and the disassembly and assembly process is cumbersome, resulting in excessive downtime for equipment maintenance. This directly affects production efficiency and product qualification rate, and seriously restricts the enterprise's large-scale production process. In view of this, we propose a device for precise slicing of Chinese herbal medicine slices with adjustable thickness. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a precision slicing device for Chinese herbal medicine slices with adjustable thickness, thereby solving the problems of easy material conveying deviation, easy damage or slippage during fixing, difficulty in accurately controlling the slice thickness, and cumbersome blade maintenance in existing Chinese herbal medicine slicing equipment.

[0004] A device for precisely slicing traditional Chinese medicine decoction pieces with adjustable thickness, comprising: A second belt conveyor is provided on top of the first belt conveyor. A U-shaped plate is fixedly installed on the top of the second belt conveyor and on one side of the first belt conveyor. A drive plate and a blade are provided inside the U-shaped plate. The blade is located below the drive plate. A stop block is provided inside the U-shaped plate and on one side of the first belt conveyor. A quick-release assembly, located within the drive plate, is used for quick disassembly of the blade; A drive assembly, located at the top of the U-shaped plate, is used to drive the drive plate to move up and down; A fixing component is located inside the first belt conveyor and is used to compress and fix the material.

[0005] Preferably, the quick-release assembly includes a spring, which is disposed within a drive plate. Sliders are fixedly installed within the drive plate at both ends of the spring. A locking plate is fixedly installed on the side of each slider that is far apart from each other. Round-headed locking blocks are symmetrically fixedly installed on the top of the blade. The top ends of the two round-headed locking blocks penetrate the drive plate and extend to one side of the two locking plates respectively. Round rods are fixedly installed on the circumferential walls of the two sliders. The two round rods penetrate the drive plate and extend to the outside.

[0006] Preferably, the round rod is slidably connected to the drive plate, and the slider is slidably connected to the drive plate.

[0007] Preferably, the card plate is slidably connected to the drive plate, and the card plate is adapted to the round-headed card block.

[0008] Preferably, the driving assembly includes a fixed plate, which is fixedly installed on the top of the U-shaped plate. A first motor is fixedly installed on one side of the fixed plate. The output shaft of the first motor passes through the fixed plate and is fixedly installed on a disc. A slide rod is fixedly installed on the top of the driving plate. One end of the slide rod passes through the U-shaped plate and extends to the outside. A connecting rod is provided on the slide rod, and one end of the connecting rod is rotatably connected to the edge of the disc.

[0009] Preferably, the slide rod is slidably connected to the U-shaped plate, and the connecting rod is rotatably connected to the slide rod.

[0010] Preferably, the output shaft of the first motor is rotatably connected to the fixed plate.

[0011] Preferably, the fixing component includes a second motor, which is fixedly installed on one side of the first belt conveyor. Two round shafts are symmetrically arranged inside the first belt conveyor, and a conveyor belt is sleeved between the two round shafts. The surface of the conveyor belt is provided with several rubber strips. The output shaft of the second motor passes through the first belt conveyor and is fixedly connected to one of the round shafts.

[0012] Preferably, the output shaft of the second motor is rotatably connected to the first belt conveyor, and the plurality of rubber strips are arranged in a linear, equally spaced structure.

[0013] Preferably, the two circular shafts are rotatably connected to the first belt conveyor.

[0014] Compared with the prior art, the present invention has the following beneficial effects: By using a dual-belt coordinated conveying system consisting of the first and second belt conveyors, along with a positioning structure with internal blocks in a U-shaped plate, the smooth conveying and unified benchmark positioning of Chinese medicinal materials are achieved. The synchronous transmission of the dual belts can avoid problems such as tilting and jamming during material conveying, while the blocks can ensure that the starting position of slicing of different batches of materials remains consistent. This ensures the stability of the slicing operation from the source of conveying and effectively reduces the slicing position deviation caused by material offset, laying the foundation for subsequent accurate slicing. By coordinating the second motor, double round shafts, and rubber strip conveyor belt in the fixing assembly, a flexible extrusion and fixing effect on the material is achieved. The linearly and equally spaced rubber strips not only enhance the friction with the material surface, preventing the material from sliding during slicing, but also protect the integrity of the material through flexible contact, preventing material damage caused by hard extrusion. The double round shaft drives the conveyor belt to transmit smoothly, ensuring that the extrusion force is evenly distributed, allowing the material to maintain a stable posture throughout the slicing process, and significantly improving the thickness uniformity of the medicinal slices. By linking the first motor, disc, connecting rod, and slide bar in the drive assembly, and combining the adjustable design of motor speed and belt conveyor speed, precise control of slice thickness and continuous operation are achieved. The transmission structure of the disc and connecting rod converts the circular motion into the stable reciprocating lifting and lowering of the slide bar, driving the blade to cut at a uniform speed. By adjusting the speed of the first motor or the conveyor speed, it can flexibly adapt to the processing needs of different thicknesses of medicinal slices, with a wide range of adaptability. The continuous slicing process does not require frequent manual intervention, which greatly improves the processing efficiency of Chinese medicinal slices and meets the needs of large-scale production. By using a quick-release assembly consisting of a spring, slider, and locking plate within the drive plate, which works in conjunction with the blade's round head locking block, rapid blade removal and convenient maintenance are achieved. Simply pressing the round rod drives the locking block to disengage from the round head locking block, thus removing the blade. After releasing, the spring automatically resets to complete the locking and fixing, eliminating the need for complex tools and significantly shortening the operation time for blade replacement and cleaning. This structure lowers the technical threshold and labor costs for equipment maintenance, reduces equipment downtime for maintenance, improves the overall utilization rate of the equipment, and provides a guarantee for long-term stable production.

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] Please see Figures 1-8 This invention provides a device for precisely slicing traditional Chinese medicine decoction pieces with adjustable thickness, comprising: A second belt conveyor 2 is mounted on top of a first belt conveyor 1. A U-shaped plate 3 is fixedly installed on the top of the second belt conveyor 2 and on one side of the first belt conveyor 1. A drive plate 14 and a blade 13 are located inside the U-shaped plate 3, with the blade 13 positioned below the drive plate 14. A stop block 12 is located inside the U-shaped plate 3 and on one side of the first belt conveyor 1. A quick-release assembly is located inside the drive plate 14 and is used for quick disassembly of the blade 13. A drive assembly is located on top of the U-shaped plate 3 and is used to drive the drive plate 14 to move up and down. A fixing assembly is located inside the first belt conveyor 1 and is used to compress and fix the material. The first belt conveyor 1 and the second belt conveyor 2 are then started. The material to be sliced ​​is placed on the collaborative conveying surface of the double belt conveyor. Through the synchronous transmission of the double belts, the material is smoothly transported to the slicing area inside the U-shaped plate 3. During the material transport process, one end of the material contacts the stop block 12 inside the U-shaped plate 3 to achieve the positioning reference before slicing, ensuring that the starting position of the slices is uniform and laying the foundation for accurate slicing. During the material extrusion and fixing stage, the second motor 9 in the fixing component is started synchronously. The output shaft of the second motor 9 passes through the first belt conveyor 1 and drives the round shaft 20 fixedly connected to it to rotate. Through the transmission action of the conveyor belt 10, the other round shaft 20 is driven to rotate synchronously. The rubber strips 11 with linear and equal spacing on the surface of the conveyor belt 10 move with the belt, applying a flexible extrusion force from above the material. In conjunction with the second belt conveyor 2 below, a clamping and fixing effect is formed, preventing uneven slice thickness caused by material displacement or shaking during slicing. During the linkage phase of the slicing drive mechanism, the first motor 8 in the drive assembly is activated. The output shaft of the first motor 8 passes through the fixed plate 4 and drives the disc 5 to rotate. The edge of the disc 5 is rotatably connected to one end of the connecting rod 6, and the other end of the connecting rod 6 is rotatably connected to the slide rod 7. The circular motion of the disc 5 is converted into the reciprocating linear motion of the slide rod 7 through the connecting rod 6. Because the slide rod 7 is slidably connected to the U-shaped plate 3 and the bottom of the slide rod 7 is fixed to the drive plate 14, the drive plate 14 moves up and down synchronously with the slide rod 7 along the guide direction of the U-shaped plate 3. The blade 13 below the drive plate 14 then completes the cycle of descending, slicing, rising, and resetting. In the thickness adjustment and precise slicing stage, based on the target slice thickness requirements, the slice thickness is precisely controlled by adjusting the speed of the first motor 8 or the conveying speed of the first and second belt conveyors 2. When the fixed material is continuously conveyed to below the blade 13, the blade 13 periodically descends under the drive plate 14 to cut and slice the material. The sliced ​​Chinese herbal medicine slices are then conveyed by the second belt conveyor 2 to subsequent collection or processing steps, completing the continuous precise slicing operation. In the quick-release maintenance stage, when the blade 13 is worn and needs to be replaced or cleaned, the two round rods 15 of the quick-release assembly are operated. Pressing the round rods 15 inward causes the round rods 15 to drive the slider 18 to slide along the inside of the drive plate 14, compressing the springs 17 at both ends of the slider 18.Simultaneously, the retaining plate 19 on one side of the slider 18 moves synchronously and disengages from the round-headed retaining block 16 at the top of the blade 13, allowing the blade 13 to be removed directly. When installing a new blade 13, align the round-headed retaining block 16 of the blade 13 with the corresponding slot on the drive plate 14, release the round rod 15, and the spring 17 returns to its original position, pushing the slider 18 and retaining plate 19 to move in opposite directions. The retaining plate 19 then re-engages with the round-headed retaining block 16, completing the quick installation and removal of the blade 13 and significantly improving equipment maintenance efficiency.

[0019] This invention provides a device for precisely slicing Chinese herbal medicine slices with adjustable thickness, which, in addition to the above-mentioned technical solutions, also has the following technical features.

[0020] The quick-release assembly includes a spring 17, which is disposed within a drive plate 14. Sliders 18 are fixedly mounted at both ends of the spring 17 within the drive plate 14. A retaining plate 19 is fixedly mounted on the side of each slide 18 that is far apart from the other. Round-headed retaining blocks 16 are symmetrically fixedly mounted on the top of the blade 13. The tops of the two round-headed retaining blocks 16 penetrate the drive plate 14 and extend to one side of each retaining plate 19. Round rods 15 are fixedly mounted on the circumferential walls of the two slides 18, penetrating the drive plate 14 and extending to the outside. During the quick-release maintenance phase, when the blade 13 shows wear and needs replacement or cleaning, [the quick-release assembly is used]. By operating the two round rods 15 of the quick-release assembly and pressing them inward, the round rods 15 drive the slider 18 to slide along the inside of the drive plate 14. The slider 18 compresses the springs 17 at both ends, and at the same time, the locking plate 19 on one side of the slider 18 moves synchronously and disengages from the round head locking block 16 at the top of the blade 13, allowing the blade 13 to be removed directly. When installing a new blade 13, align the round head locking block 16 of the blade 13 with the corresponding slot on the drive plate 14 and insert it. Release the round rods 15, and the springs 17 return to their original positions, pushing the slider 18 and the locking plate 19 to move in opposite directions. The locking plate 19 then re-engages with the round head locking block 16, completing the quick installation and removal of the blade 13 and significantly improving equipment maintenance efficiency.

[0021] This invention provides a device for precisely slicing Chinese herbal medicine slices with adjustable thickness, which, in addition to the above-mentioned technical solutions, also has the following technical features.

[0022] The round rod 15 is slidably connected to the drive plate 14, and the slider 18 is also slidably connected to the drive plate 14. This sliding connection ensures that the slider 18 can move smoothly inside the drive plate 14 when the round rod 15 is operated. The sliding of the round rod 15 on the drive plate 14 provides a power transmission path for the movement of the slider 18, allowing the operator to easily control the position of the slider 18 by pressing the round rod 15. The sliding of the slider 18 within the drive plate 14 is the key to realizing the quick-release function of the blade 13. During long-term use of the equipment, the sliding fit between the round rod 15, the slider 18, and the drive plate 14 will not easily become loose or jammed. This is because strict requirements are placed on the material selection and processing precision of the round rod 15, the slider 18, and the drive plate 14 during the design and manufacturing process.

[0023] This invention provides a device for precisely slicing Chinese herbal medicine slices with adjustable thickness, which, in addition to the above-mentioned technical solutions, also has the following technical features.

[0024] The clamping plate 19 is slidably connected to the drive plate 14, and the clamping plate 19 is adapted to the round-headed clamping block 16. This adaptation relationship allows the round-headed clamping block 16 to closely cooperate with the clamping plate 19 during movement. When the round rod 15 slides and drives the round-headed clamping block 16 to move, the round-headed clamping block 16 can accurately engage with the corresponding position of the clamping plate 19. The sliding of the clamping plate 19 on the drive plate 14 provides flexibility for its cooperation with the round-headed clamping block 16. The operator can adjust the position of the clamping plate 19 according to actual needs, thereby changing the engagement state of the round-headed clamping block 16 and the clamping plate 19. Through this engagement and disengagement operation, effective control of the installation and disassembly of the blade 13 can be achieved.

[0025] This invention provides a device for precisely slicing Chinese herbal medicine slices with adjustable thickness, which, in addition to the above-mentioned technical solutions, also has the following technical features.

[0026] The drive assembly includes a fixed plate 4, which is fixedly installed on the top of the U-shaped plate 3. A first motor 8 is fixedly installed on one side of the fixed plate 4. The output shaft of the first motor 8 passes through the fixed plate 4 and is fixedly installed on a disc 5. A slide rod 7 is fixedly installed on the top of the drive plate 14. One end of the slide rod 7 passes through the U-shaped plate 3 and extends to the outside. A connecting rod 6 is provided on the slide rod 7. One end of the connecting rod 6 is rotatably connected to the edge of the disc 5. The output shaft of the first motor 8 passes through the fixed plate 4 and drives the disc 5 to rotate. The edge of the disc 5 is rotatably connected to one end of the connecting rod 6. The other end of the connecting rod 6 is rotatably connected to the slide rod 7. The circular motion of the disc 5 is converted into the up-and-down reciprocating linear motion of the slide rod 7 through the connecting rod 6. Because the slide rod 7 is slidably connected to the U-shaped plate 3 and the bottom of the slide rod 7 is fixed to the drive plate 14, the drive plate 14 moves up and down synchronously with the slide rod 7 along the guiding direction of the U-shaped plate 3. The blade 13 below the drive plate 14 then completes the cycle of descending, slicing, rising, and resetting.

[0027] This invention provides a device for precisely slicing Chinese herbal medicine slices with adjustable thickness, which, in addition to the above-mentioned technical solutions, also has the following technical features.

[0028] In this system, the slide rod 7 is slidably connected to the U-shaped plate 3, and the connecting rod 6 is rotatably connected to the slide rod 7. The circular motion of the disc 5 is efficiently converted into the linear motion of the slide rod 7. During the process of the slide rod 7 sliding up and down along the U-shaped plate 3, the U-shaped plate 3 plays a precise guiding role, ensuring the stability and accuracy of the slide rod 7's motion. The rotatable connection between the connecting rod 6 and the slide rod 7 makes the force transmission smoother and reduces the jamming phenomenon during the motion. This rotatable connection method can adapt to the force changes generated by the disc 5 at different rotation speeds and angles, ensuring the efficient operation of the entire transmission system. When the first motor 8 continuously drives the disc 5 to rotate, the slide rod 7 will continuously perform up and down reciprocating linear motion, thereby driving the drive plate 14 and the blade 13 to continuously perform slicing actions.

[0029] This invention provides a device for precisely slicing Chinese herbal medicine slices with adjustable thickness, which, in addition to the above-mentioned technical solutions, also has the following technical features.

[0030] The output shaft of the first motor 8 is rotatably connected to the fixed plate 4. This rotatable connection not only ensures the stable rotation of the output shaft of the first motor 8, but also effectively reduces the impact of vibration caused by rotation on the entire device. The fixed plate 4 provides reliable support for the output shaft of the first motor 8, so that the output shaft will not deviate or shake during rotation.

[0031] This invention provides a device for precisely slicing Chinese herbal medicine slices with adjustable thickness, which, in addition to the above-mentioned technical solutions, also has the following technical features.

[0032] The fixing component includes a second motor 9, which is fixedly installed on one side of the first belt conveyor 1. Two round shafts 20 are symmetrically arranged inside the first belt conveyor 1, and a conveyor belt 10 is sleeved between the two round shafts 20. The surface of the conveyor belt 10 is provided with several rubber strips 11. The output shaft of the second motor 9 passes through the first belt conveyor 1 and is fixedly connected to one of the round shafts 20. The output shaft of the second motor 9 passes through the first belt conveyor 1 and drives the round shaft 20 fixedly connected to it to rotate. Through the transmission action of the conveyor belt 10, the other round shaft 20 is driven to rotate synchronously. The rubber strips 11 on the surface of the conveyor belt 10 are linearly and equally spaced. With the movement of the belt, a flexible extrusion force is applied from above to the material. This, together with the second belt conveyor 2 below, forms an upper and lower clamping and fixing effect, preventing the material from shifting or shaking due to force during slicing, which would cause uneven slice thickness.

[0033] This invention provides a device for precisely slicing Chinese herbal medicine slices with adjustable thickness, which, in addition to the above-mentioned technical solutions, also has the following technical features.

[0034] The output shaft of the second motor 9 is rotatably connected to the first belt conveyor 1. Several rubber strips 11 are arranged in a linear and equally spaced structure. This structural design allows the rubber strips 11 to apply a flexible extrusion force to the material evenly under the drive of the conveyor belt 10. During the slicing process, the equal spacing between the rubber strips 11 ensures the uniformity of the force applied to the material. When the material is placed between the first belt conveyor 1 and the second belt conveyor 2, the evenly distributed rubber strips 11 pass over the material one by one, avoiding the slight sliding or tilting of the material in the horizontal direction due to uneven local force.

[0035] This invention provides a device for precisely slicing Chinese herbal medicine slices with adjustable thickness, which, in addition to the above-mentioned technical solutions, also has the following technical features.

[0036] Two circular shafts 20 are rotatably connected to the first belt conveyor 1. During the operation of the device, the two circular shafts 20 rotate synchronously, driving the belt of the first belt conveyor 1 to run smoothly. This rotatable connection method enables the belt to maintain a uniform and stable speed when conveying materials, avoiding belt slippage or shaking, thereby ensuring that the materials can be accurately conveyed to the slicing position.

[0037] Working principle: Start the first belt conveyor 1 and the second belt conveyor 2. The material to be sliced ​​is placed on the collaborative conveying surface of the two belt conveyors. The material is smoothly conveyed to the slicing operation area inside the U-shaped plate 3 through the synchronous transmission of the two belts. During the material conveying process, one end of the material contacts the stop block 12 inside the U-shaped plate 3 to realize the positioning reference before slicing, ensure the uniformity of the slicing starting position, and lay the foundation for accurate slicing. During the material extrusion and fixing stage, the second motor 9 in the fixing assembly is started synchronously. The output shaft of the second motor 9 passes through the first belt conveyor 1 and drives the round shaft 20 fixedly connected to it to rotate. Through the transmission action of the conveyor belt 10, it drives another round shaft 20 to rotate synchronously. The rubber strips 11 with linear and equal spacing on the surface of the conveyor belt 10 move with the belt and apply a flexible extrusion force from above the material. Together with the second belt conveyor 2 below, it forms an upper and lower clamping and fixing effect, which avoids uneven slice thickness caused by the material shifting or shaking due to force during slicing. During the linkage phase of the slicing drive mechanism, the first motor 8 in the drive assembly is activated. The output shaft of the first motor 8 passes through the fixed plate 4 and drives the disc 5 to rotate. The edge of the disc 5 is rotatably connected to one end of the connecting rod 6, and the other end of the connecting rod 6 is rotatably connected to the slide rod 7. The circular motion of the disc 5 is converted into the up-and-down reciprocating linear motion of the slide rod 7 through the connecting rod 6. Since the slide rod 7 is slidably connected to the U-shaped plate 3 and the bottom of the slide rod 7 is fixed to the drive plate 14, the drive plate 14 moves up and down synchronously with the slide rod 7 along the guide direction of the U-shaped plate 3. The blade 13 below the drive plate 14 then completes the cycle of descending, slicing, rising, and resetting. In the thickness adjustment and precise slicing stage, the slice thickness is precisely controlled by adjusting the speed of the first motor 8 or the conveying speed of the first and second belt conveyors 2 according to the target slice thickness requirements. When the fixed material is continuously conveyed to the blade 13, the blade 13 is driven by the drive plate 14 to periodically move downward to cut and slice the material. The sliced ​​Chinese medicine slices are then conveyed by the second belt conveyor 2 to the subsequent collection or processing steps to complete the continuous precise slicing operation. During the quick-release maintenance phase of blade 13, when blade 13 is worn and needs to be replaced or cleaned, operate the two round rods 15 of the quick-release assembly. Press the round rods 15 inward, and the round rods 15 will drive the slider 18 to slide along the inside of the drive plate 14. The slider 18 will compress the springs 17 at both ends, and at the same time, the locking plate 19 on one side of the slider 18 will move synchronously and disengage from the round head locking block 16 on the top of the blade 13, so the blade 13 can be removed directly. When installing a new blade 13, align the round head locking block 16 of the blade 13 with the corresponding slot on the drive plate 14 and insert it. Release the round rods 15, and the springs 17 will return to their original positions, pushing the slider 18 and the locking plate 19 to move in the opposite direction. The locking plate 19 will re-engage with the round head locking block 16, completing the quick disassembly and assembly of the blade 13, which greatly improves the equipment maintenance efficiency.
