Description

Technical Field

[0001] This invention relates to the field of slicing technology, and in particular to a low-temperature vibration precision slicing device for Dendrobium huoshanense. Background Technology

[0002] Dendrobium huoshanense, a perennial herb belonging to the Dendrobium genus of the Orchidaceae family, is a rare and precious traditional Chinese medicine unique to my country. Its stems are rich in various active ingredients such as Dendrobium polysaccharides, alkaloids, and amino acids, possessing medicinal effects such as nourishing yin and stomach, promoting fluid production and moistening the lungs. It occupies an important position in the field of traditional Chinese medicine and the high-end health product market. With the increasing market demand for deep-processed Dendrobium huoshanense products, slicing, as a key pretreatment step, directly affects the product's appearance quality, efficacy stability, and subsequent processing efficiency. Therefore, stringent requirements are placed on the precision, integrity, and preservation of active ingredients in slicing techniques. The stem segments of Dendrobium huoshanense have a fleshy stem structure, are crisp and tender, and rich in mucilage. They are easily deformed by external pressure at room temperature, and the fibrous tissue is unevenly distributed with significant differences in the thickness of the internodes. During the slicing process, the mucilage component is easily melted by the heat generated by the friction of the blade, causing the slices to stick to the blade surface, forming a "dragging" phenomenon. This not only causes severe tearing and burrs on the slice edges, but also reduces processing efficiency due to repeated cleaning of the blade. Conventional mechanical slicing relies on the unidirectional cutting force of a high-speed rotating blade. Friction generates heat, causing the local temperature to rise above 40°C. This leads to the oxidation and decomposition of heat-sensitive alkaloids (such as dendrobine) in Dendrobium huoshanense, reducing the retention rate of medicinal components by 15% to 20%. When gelatinous or fibrous tissues become entangled in the blade, jamming can easily occur, forcing the equipment to stop for cleaning. The average effective processing time per day for a single machine is less than 6 hours, which is insufficient to meet the needs of large-scale production. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the slicing device in the prior art is prone to jamming. To address this, we propose a low-temperature vibration precision slicing device for Dendrobium huoshanense.

[0004] To achieve the above objectives, this application adopts the following technical solution: a low-temperature vibration precision slicing device for Dendrobium huoshanense, comprising a worktable, a low-temperature chamber fixedly connected to the top of the worktable, a motion stage inside the low-temperature chamber, a plurality of evenly distributed cutting blades mounted on the surface of the motion stage, a drive assembly provided on one side of the motion stage, and a vibration assembly provided at the bottom of the motion stage. The drive assembly includes a servo motor, the output end of which is fixedly connected to a rotating disk. An annular groove is formed on the surface of the rotating disk. Multiple teeth are fixedly connected to both the inner and outer walls of the annular groove. A connecting gear is built into the annular groove and meshes with the annular groove through the teeth. A connecting rod is hinged to the side of the connecting gear away from the rotating disk. A motion seat is sleeved on the end of the connecting rod near the worktable. The motion seat is slidably connected to the worktable surface. A push plate is slidably sleeved on the top of the motion seat. The end of the push plate away from the motion seat is fixedly connected to the motion table. The vibration assembly includes two connecting seats, which are fixedly connected to the two sides of the motion table respectively. A motor is provided on the top of the connecting seat, and a rotating seat is provided at the output end of the motor. Multiple protrusions are fixed around the rotating seat. The side of the protrusion away from the rotating seat is slidably connected to the connecting seat. An arc surface is provided on the top of the connecting seat, and the protrusion is slidably connected to the arc surface.

[0005] Preferably, the workbench has multiple evenly distributed feet fixedly connected around its bottom perimeter, and the workbench surface has a material window.

[0006] Preferably, a partition is provided between the plurality of cutters, the bottom of the partition is fixedly connected to the motion table, and the plurality of protrusions are evenly distributed around the axis of the rotating seat.

[0007] Preferably, the low-temperature chamber is equipped with a sealing cover on the top, and a handle is fixedly connected to the top of the sealing cover. The low-temperature chamber has assembly windows that penetrate through it on both sides, and the motion table is placed in the assembly window. The motion table is slidably connected to the inner wall of the assembly window.

[0008] Preferably, the servo motor is fitted with a housing, and the servo motor is located on one side of the worktable.

[0009] Preferably, the plurality of teeth are evenly distributed around the axis of the rotating disk, and the end of the connecting rod away from the rotating disk extends to the surface of the worktable.

[0010] Preferably, the worktable surface is equipped with guide rails to ensure that the motion seat only moves axially.

[0011] Preferably, the connecting seat is located on the side of the motion table away from the drive assembly, and the connecting seats on both sides are symmetrically distributed along the axis of the motion table.

[0012] Preferably, a fixing seat is sleeved and fixed on the surface of the motor, and the end of the fixing seat away from the motor is fixedly connected to the workbench surface.

[0013] Preferably, a drive roller is fixedly connected to the output end of the motor, and the end of the drive roller away from the motor is fixedly connected to the rotating seat.

[0014] The technical effects and advantages of this invention are as follows: The slicing device of this invention achieves efficient and anti-jamming slicing through structural optimization and multi-component collaboration. Its basic structure includes a low-temperature chamber mounted on top of the worktable, with its inner walls insulated and fitted with a sealed lid to maintain a low-temperature environment. This not only pre-treats stem segments to prevent deformation due to compression at room temperature, but also inhibits the melting of gums due to temperature increases, reduces the impact of blade friction heat on heat-sensitive alkaloids, and improves the retention rate of medicinal components.

[0015] The core working components of the equipment include a motion table, a drive assembly, and a vibration assembly. Through a rotating disc, connecting gears, and connecting rods, the motion table reciprocates along the assembly window. The precision of the servo motor ensures a stable cutting rhythm and enables continuous cutting. The vibration assembly works synchronously with the drive assembly: the motor drives the drive roller and rotating seat to rotate, and the protrusions on the rotating seat slide into contact with the arc surfaces of the connecting seats on both sides of the motion table, causing the motion table to vibrate at high frequency. This micro-vibration can promptly dislodge fibers and adhesives that may entangle the cutting tool. Combined with the low-temperature environment's suppression of adhesive melting, this fundamentally solves the jamming problem and reduces downtime for cleaning.

[0016] Compared to traditional equipment, this equipment organically combines low-temperature environment, reciprocating cutting, and high-frequency micro-vibration: low temperature inhibits the melting of adhesive, reciprocating motion ensures stable cutting force, high-frequency micro-vibration prevents entanglement, and multi-stage collaboration greatly reduces the probability of jamming, increases the average daily effective processing time, meets the needs of large-scale production, and has both high efficiency and protection of drug efficacy components.

[0019] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0020] Reference Figures 1 to 7 As shown, the present invention provides a technical solution: a low-temperature vibration precision slicing device for Dendrobium officinale, comprising a worktable 1, with multiple evenly distributed feet 101 fixedly connected around the bottom of the worktable 1, a material window 102 on the surface of the worktable 1, a low-temperature chamber 2 fixedly connected to the top of the worktable 1, a moving platform 3 inside the low-temperature chamber 2, multiple evenly distributed cutters 301 mounted on the surface of the moving platform 3, partitions 302 arranged between the multiple cutters 301, the bottom of the partitions 302 fixedly connected to the moving platform 3, a drive assembly 4 arranged on one side of the moving platform 3, and a vibration assembly 5 arranged at the bottom of the moving platform 3; the multiple feet 101 are made of a material with a certain degree of elasticity, which can not only stably support the device on the ground, but also absorb some of the vibration generated during the operation of the device, reduce the impact of the device on the ground, and reduce the noise generated during the operation of the device, and avoid the impact of excessive vibration on the coordination accuracy of each component. The height of the feet 101 can be finely adjusted, so that the operator can adjust the level of the worktable 1 according to the flatness of the ground to ensure that the device operates in a horizontal state.

[0021] A sealing cover 201 is installed on the top of the low-temperature chamber 2, and a handle 202 is fixedly connected to the top of the sealing cover 201. Assembly windows 203 are provided on both sides of the low-temperature chamber 2, penetrating through it. The moving platform 3 is placed in the assembly window 203, and the moving platform 3 is slidably connected to the inner wall of the assembly window 203. First, the *Dendrobium huoshanense* stem segments are placed into the low-temperature chamber 2 through the material window 102 on the surface of the working platform 1. The low-temperature chamber 2 provides a low-temperature environment for the stem segments, allowing for pretreatment and effectively preventing deformation of the stem segments due to external pressure at room temperature, while also inhibiting the melting of the gelatinous components due to temperature increases. The sealing cover 201 ensures the airtightness of the low-temperature chamber 2, maintaining the internal low-temperature environment. The sealing cover 201 can be easily opened and closed using the handle 202. The inner wall of the low-temperature chamber 2 uses a special heat-insulating material to minimize heat exchange with the outside environment, ensuring that the temperature inside the chamber remains stable within a suitable range, providing continuous and reliable low-temperature conditions for the pretreatment and subsequent cutting of the stem segments. Furthermore, the size of the material window 102 is carefully designed to facilitate the lateral movement of the moving platform 3 while ensuring vertical vibration.

[0022] The drive assembly 4 includes a servo motor 401, with a housing 402 fixedly fitted onto the surface of the servo motor 401. The servo motor 401 is located on one side of the workbench 1. A rotating disk 403 is fixedly connected to the output end of the servo motor 401. An annular groove 404 is formed on the surface of the rotating disk 403. Multiple teeth 405 are fixedly connected to both the inner and outer annular walls of the annular groove 404. The multiple teeth 405 are evenly distributed around the axis of the rotating disk 403. A connecting gear 406 is built into the annular groove 404. The connecting gear 406 is connected to the annular groove 404 through the teeth 405. The connecting gear 406 is located away from the rotating disk. A connecting rod 407 is hinged to one side of the rotating disk 403. The end of the connecting rod 407 away from the rotating disk 403 extends to the surface of the worktable 1. A motion seat 408 is sleeved on the end of the connecting rod 407 near the worktable 1. The motion seat 408 is slidably connected to the surface of the worktable 1. A guide rail is installed on the surface of the worktable 1 to ensure that the motion seat 408 only moves axially. A push plate 409 is slidably sleeved on the top of the motion seat 408. The end of the push plate 409 away from the motion seat 408 is fixedly connected to the motion table 3. After the drive assembly 4 is started, the servo motor 401 starts to work, and its output end drives the rotating disk 403 to rotate. The teeth 405 on the inner and outer ring walls of the annular groove 404 on the surface of the rotating disk 403 mesh with the connecting gear 406, so that the connecting gear 406 moves together with the rotating disk 403 in the annular groove 404. The connecting gear 406, connected by a hinge, moves along with the connecting rod 407. The end of the connecting rod 407 away from the rotating disk 403 drives the motion seat 408 to slide axially along the guide rail on the worktable 1. The push plate 409 on the top of the motion seat 408 is fixedly connected to the motion table 3. When the connecting gear 406 moves to the side away from the worktable 1, the connecting rod 407 pulls the motion seat 408, which in turn pulls the motion table 3 along the inner wall of the assembly window 203 away from the drive assembly 4 via the push plate 409. When the connecting gear 406 moves to the side closer to the worktable 1, the connecting rod 407 pushes the motion seat 408, which in turn pushes the motion table 3 towards the drive assembly 4 via the push plate 409. This process is repeated to achieve the reciprocating motion of the motion table 3, which drives the cutter 301 on the surface to cut the stem segment. The servo motor 401 has extremely high operating precision and can accurately control the rotation speed of the rotating disk 403, thereby keeping the reciprocating frequency of the motion table 3 stable and ensuring a uniform cutting rhythm. The outer casing 402 provides excellent protection for the servo motor 401, isolating it from external dust, moisture, and debris that may be generated during the cutting process. This prevents these impurities from affecting the normal operation of the motor and extends its service life. The meshing point between the connecting gear 406 and the teeth 405 of the annular groove 404 undergoes special lubrication treatment, reducing frictional resistance during movement. This not only makes the transmission smoother but also reduces the wear rate of components, ensuring the long-term stable operation of the drive assembly 4.The surface of the guide rail is very smooth, and the fit clearance with the motion seat 408 has been precisely adjusted so that the motion seat 408 will not jam or shift during the sliding process, ensuring the accurate reciprocating motion trajectory of the motion table 3 and providing a solid foundation for the stable cutting of the cutter 301.

[0023] Meanwhile, two connecting seats 501 are provided on the vibration component 5. The two connecting seats 501 are fixedly connected to the two sides of the motion table 3 respectively. The connecting seats 501 are located on the side of the motion table 3 away from the drive component 4. The two connecting seats 501 are symmetrically distributed along the axis of the motion table 3. A motor 502 is provided on the top of the connecting seat 501. A fixed seat 503 is sleeved and fixed on the surface of the motor 502. The end of the fixed seat 503 away from the motor 502 is fixedly connected to the table surface of the worktable 1. A drive roller 504 is fixedly connected to the output end of the motor 502. The end of the drive roller 504 away from the motor 502 is fixedly connected to the rotating seat 505. A rotating seat 505 is provided at the output end of the motor 502. Multiple protrusions 506 are fixed around the rotating seat 505. The multiple protrusions 506 are evenly distributed around the axis of the rotating seat 505. The side of the protrusion 506 away from the rotating seat 505 is slidably connected to the connecting seat 501. An arc surface 507 is opened on the top of the connecting seat 501. The protrusion 506 is slidably connected to the arc surface 507. While the drive assembly 4 drives the motion table 3 in reciprocating motion, the vibration assembly 5 also works synchronously, which plays a crucial role in preventing jamming. The motor 502 starts, and its output drives the drive roller 504 and the rotating seat 505 to rotate. Multiple protrusions 506 around the rotating seat 505 rotate together with it. The side of the protrusion 506 furthest from the rotating seat 505 is slidably connected to the arc surface 507 on the top of the connecting seat 501. When the protrusion 506 moves close to the connecting seat 501, it lifts the connecting seat 501, thereby driving the motion table 3 upwards; when the protrusion 506 moves away from the connecting seat 501, the motion table 3 falls under its own gravity. Because the protrusions 506 are evenly distributed around the axis of the rotating seat 505 and rotate at high speed with the rotating seat 505, the motion table 3 achieves high-frequency micro-vibration. This high-frequency micro-vibration allows the cutter 301 to continuously generate minute up-and-down vibrations during the cutting process. When encountering fibrous tissue or gum in the stem segment that tends to entangle the cutter, the minute vibrations can dislodge them, preventing the accumulation of fibers or gum on the cutter and effectively preventing jamming. The mounting base 503 on the surface of the motor 502 not only serves a fixing function but also absorbs some of the vibration generated during motor operation, reducing the transmission of vibration to other parts of the worktable 1. This prevents the entire equipment from becoming loose or damaged due to excessive vibration, ensuring that the vibration component 5 can stably generate high-frequency micro-vibrations and continuously perform its anti-jamming function. The drive roller 504 is made of a material with high strength and wear resistance, which can stably transmit the power of the motor 502 and ensure the stable rotation speed of the rotating seat 505, thereby keeping the high-frequency micro-vibration frequency of the moving table 3 consistent and ensuring the stability of the anti-jamming effect. The arc surface 507 on the top of the connecting seat 501 is finely polished, with extremely high surface smoothness, making the contact with the protrusion 506 smoother, reducing the coefficient of friction between the two, reducing wear on the parts, and making the up-and-down movement of the motion table 3 more stable, so that the high-frequency micro-vibration can act evenly on the cutter 301, preventing jamming in all directions.

[0024] The low-temperature chamber 2 effectively prevents the melting of the gum in Dendrobium officinale stem segments due to temperature increases during cutting, thus reducing the likelihood of slices sticking to the blade surface and preventing gum accumulation that could cause jamming. It also eliminates the need for repeated blade cleaning, improving processing efficiency. The high-frequency micro-vibration of the motion table 3 allows the cutter 301 to promptly dislodge any fibers and gum that might entangle the blade during cutting, making the cutting process smoother and significantly reducing the probability of jamming. The cutter 301 is made of a special high-strength, high-hardness material, with a sharp and wear-resistant blade that easily cuts stem segments, reducing cutting resistance and jamming caused by cutting difficulties. It also maintains good cutting performance over a long period, reducing the frequency of blade replacement and further improving the continuous working capacity of the equipment. The partition 302 divides the surface of the motion table 3 into multiple independent cutting areas, preventing stem segments from squeezing and stacking together during cutting. This ensures that each stem segment receives uniform cutting force, preventing excessive force caused by stem segment stacking and jamming, thus improving cutting smoothness. Furthermore, the low-temperature environment reduces the impact of heat generated by blade friction on the heat-sensitive alkaloids in Dendrobium officinale, lowering the oxidative decomposition of medicinal components such as dendrobine and improving the retention rate of medicinal components. Simultaneously, by reducing jamming caused by the entanglement of gelatinous or fibrous tissue around the blade, the equipment does not require frequent shutdowns for cleaning, extending the average daily effective processing time of a single unit and better meeting the needs of large-scale production. The drive assembly 4, through the cooperation of components such as the servo motor 401, rotating disk 403, connecting gear 406, and connecting rod 407, achieves stable reciprocating motion of the motion table 3, ensuring the continuity and stability of the cutting process, avoiding jamming caused by unstable motion, and further improving the equipment's working efficiency and slice quality. The arc surface 507 design on the top of the connecting seat 501 in the vibration assembly 5 makes the contact between the convex seat 506 and the connecting seat 501 smoother, reducing frictional wear between components, extending the service life of the equipment, and ensuring that the high-frequency micro-vibration can stably and continuously play its anti-jamming role.

[0025] Compared to traditional slicing equipment, this device organically combines a low-temperature environment, reciprocating cutting, and high-frequency micro-vibration to form a highly efficient, anti-jamming slicing system. Traditional equipment often suffers from jamming due to the large amount of heat generated by the high-speed rotating blades, causing the adhesive to melt and entangle around the blades. Furthermore, the lack of effective vibration assistance makes jamming a common problem. This device, however, uses a low-temperature environment to inhibit adhesive melting, high-frequency micro-vibration to promptly remove any potentially entangled fibers and adhesive, and reciprocating motion to ensure stable cutting force. These multiple synergistic effects fundamentally solve the jamming problem, allowing the equipment to operate continuously and stably for extended periods, significantly improving production efficiency and better meeting the stability requirements of large-scale production.

[0026] The technical scope of this invention is not limited to the content described above.
