Abstract
Description
Technical Field
[0001] This invention relates to the field of medicinal material processing, and in particular to a rotary table-type Chinese medicine cutting machine. Background Technology
[0002] In the current field of Chinese medicinal herb processing, rotary herb slicers are the core equipment for achieving large-scale slicing of medicinal materials, and their technological development directly affects the efficiency and quality of Chinese medicinal herb production. With the diversification of Chinese medicinal herb varieties and the refinement of processing requirements, the market has placed higher demands on the adaptability, stability, and medicinal herb protection capabilities of herb slicers. However, existing rotary herb slicers still have certain limitations in structural design and control strategies, making it difficult to fully meet complex processing needs.
[0003] Common rotary herb slicers typically employ a fixed blade layout, where the blade spacing cannot be flexibly adjusted according to the shape, size, and slice thickness requirements of the medicinal materials. This results in poor adaptability to different types of medicinal materials, often leading to problems such as material jamming due to insufficient spacing or incomplete slices due to excessive spacing, thus limiting the equipment's application range. Furthermore, traditional equipment lacks effective real-time mechanical monitoring and dynamic adjustment mechanisms. It cannot detect changes in the hardness of the medicinal materials during cutting, and the servo motor speed and feed rate are usually kept constant. When encountering herbs with high hardness, excessive cutting force can easily cause the herbs to be crushed, while herbs with low hardness may result in uneven slice thickness due to insufficient cutting force, severely affecting the stability of slice quality. In addition, the single-cutting mode of a single set of blades concentrates the cutting load. Herbs with complex fibrous structures or fragile textures are prone to breakage due to excessive local stress during processing, increasing the risk of loss of active ingredients. It is difficult to balance cutting efficiency and herb integrity, failing to meet the requirements of medicinal material processing applications. Therefore, a rotary herb slicer is proposed.

The first assembly integrates a servo drive module, a central controller, and a closed-loop control module. The pressure sensor is connected to the central controller via a CAN bus. The central controller has an FFT algorithm installed inside. The third connector secures the pressure sensor. The pressure sensor can collect the blade force data in real time and transmit it to the central controller via the CAN bus. The central controller uses the FFT algorithm to analyze the data and, in conjunction with the servo drive module and the closed-loop control module, achieves dynamic adjustment, ensuring the accuracy and quality of the slice.
[0005] Preferably, the output end of the first linear drive component passes through the corresponding position of the first connector, and the exterior of the first linear drive component is connected to the corresponding position of the first connector by bolts.

[0007] Preferably, the first connector has sliding rails on both sides inside, and sliders are inserted inside the sliding rails. The outer ends of the sliders are connected to the outside of the first and second adjusting members on the corresponding sides.

The main core of the dual-core processing unit runs the FFT algorithm and real-time control logic, while the secondary core is responsible for the encrypted storage and trend analysis of historical processing data. It also automatically generates optimization suggestions for cutting parameters of different medicinal materials and displays them visually on the operation panel. The main core and secondary core of the dual-core processor are synchronized through an internal data bus. The dual cores have a clear division of labor, which not only ensures the efficiency of real-time control but also provides optimization suggestions through in-depth data analysis, thereby improving the intelligence level of the equipment and the processing accuracy.
[0012] Preferably, the closed-loop control module is further equipped with a disturbance compensation submodule. The disturbance compensation submodule and the feedback data from the pressure sensor form a dual closed-loop adjustment.

[0013] Preferably, the pressure sensor adopts an array-type redundant design, with 1-3 groups of pressure sensors. Each pressure sensor is connected to the central controller through an independent CAN bus branch. The redundancy design improves the reliability of pressure detection. If one group fails, the other groups can continue to work. The independent bus ensures stable data transmission and ensures timely and accurate pressure feedback.
[0014] In summary, compared with the prior art, the present invention provides a rotary herb cutting machine with the following beneficial effects: 1. The present invention drives the movement of the first adjusting component through the first linear drive component, thereby adjusting the distance between the first adjusting component and the second adjusting component with the cooperation of the telescopic bracket. This achieves flexible adjustment of the blade spacing and can accurately adapt the blade spacing according to the shape, size and slicing requirements of different medicinal materials. This greatly improves the equipment's adaptability to diverse processing scenarios and avoids processing limitations caused by fixed blade positions. As a result, it provides a more flexible operating space for slicing various medicinal materials and effectively expands the application range of the equipment. 2. This invention forms a dynamic adjustment system through a pressure sensor and a central controller. By collecting the force data of the rotary cutting wheel in real time and analyzing the hardness characteristics of the medicinal material using the FFT algorithm, the system can synchronously and precisely adjust the rotation speed of the drive components and the displacement of the first and second linear drive components. When encountering medicinal materials with high hardness, the system automatically reduces the rotation speed and feed rate, maintaining a constant slicing shearing force and ensuring the consistency of the slicing process. At the same time, with the cooperation of two sets of rotary cutting wheels, one set of rotary cutting wheels pre-treats the surface of the medicinal material, while the other set of rotary cutting wheels completes the main slicing work. This layered cutting mode significantly reduces the load of a single cut, reduces the breakage of the medicinal material due to compression, and improves the integrity and uniformity of the slices.

Please see Figure 1 The back of the chassis 1 is equipped with a mounting bracket 2. A mounting component 3 is mounted on the upper outer side of the mounting bracket 2. A first mounting accessory 4 is mounted on the top of the mounting component 3. Both the mounting component 3 and the first mounting accessory 4 are chassis components. Please refer to [link / reference]. Figure 2 An operation panel 5 is installed on the outer side of the mounting bracket 2; The cutting table 6 is mounted on top of the chassis 1. A conveyor assembly 7, which is a conveyor belt mechanism, is installed inside the cutting table 6. (See [link to documentation]). Figure 3 and Figure 4 The first connector 8 is inserted inside the mounting component 3, and the first linear drive assembly 9 is installed on the outside of the first connector 8. The output end of the first linear drive assembly 9 passes through the corresponding position of the first connector 8. The outside of the first linear drive assembly 9 is connected to the corresponding position of the first connector 8 by bolts. The first connector 8 is U-shaped and has a plate frame structure. The second connector 10 is connected to the output end of the first linear drive assembly 9. The back of the second connector 10 is connected to the first adjusting member 11. The outside of the first adjusting member 11 is hinged to the telescopic bracket 24. The outer end of the telescopic bracket 24 is hinged to the second adjusting member 12. The rear middle position of the telescopic bracket 24 is hinged to the mating member 23 through the bearing. The back of the mating member 23 is connected to the corresponding position on the outside of the first connector 8. The mating member 23 is a strip structure. Please see Figure 6 The first connecting member 8 has sliding rails 21 on both sides inside, and sliders 22 are inserted inside the sliding rails 21. The outer ends of the sliders 22 are connected to the outside of the first adjusting member 11 and the second adjusting member 12 on the corresponding side. The first adjusting member 11 and the second adjusting member 12 are both plate-shaped structures. Please see Figure 4 The second assembly 13 is connected to the front side of the first adjusting member 11 and the second adjusting member 12. Please refer to [link / reference]. Figure 5 The lower part of the second assembly 13 is equipped with a drive component 16, which is a stepper motor. The drive component 16 is fitted with a third assembly 17, which is a ring bracket. The output shaft of the drive component 16 is connected to a turntable cutting wheel 18. The third connector 19 is connected to the outside of the third assembly 17. The third connector 19 is a strip bracket. A pressure sensor 20 is installed on the outside of the third connector 19. The first assembly 4 integrates a servo drive module, a central controller and a closed-loop control module. The pressure sensor 20 is connected to the central controller via a CAN bus. The central controller has an FFT algorithm. The top of the second assembly 13 is equipped with a second linear drive assembly 14. The first linear drive assembly 9 and the second linear drive assembly 14 are both electric telescopic rods. The output end of the second linear drive assembly 14 passes through the corresponding position of the second assembly 13. The output end of the second linear drive assembly 14 is coaxially connected to a flange 15. The lower part of the flange 15 is connected to the top of the third assembly 17. The servo drive module integrates an adaptive load adjustment unit, which dynamically adjusts the PWM wave duty cycle based on the cutting resistance prediction value output by the central controller. The adaptive load adjustment unit and the drive module adopt a modular plug-in structure. The central controller has a built-in dual-core processing unit. The main core of the dual-core processing unit runs the FFT algorithm and real-time control logic, while the secondary core is responsible for the encrypted storage and trend analysis of historical processing data. It also automatically generates cutting parameter optimization suggestions for different medicinal materials and displays them visually through the operation panel 5. The main core and secondary core of the dual-core processing unit are synchronized through an internal data bus. The closed-loop control module is equipped with a disturbance compensation submodule. The disturbance compensation submodule and the feedback data from the pressure sensor 20 form a dual closed-loop regulation. The compensation coefficient of the disturbance compensation submodule is adaptively and iteratively optimized by the central controller. The pressure sensor 20 adopts an array-type redundant design. The number of pressure sensors 20 is 1-3 groups. All pressure sensors 20 are connected to the central controller through independent CAN bus branches. The detailed implementation process of the above functional modules is as follows: After the equipment is started, each component enters its initial working state according to the preset program. The medicinal materials are conveyed to the cutting table 6 via the conveying component 7. As the rotary cutting wheel 18 rotates, the contact pressure between the medicinal materials and the cutting wheel is captured in real time by the pressure sensor 20. The pressure sensor 20 is installed on the outside of the third assembly 17 via the third connector 19. Multiple sets of sensing units with an array-style redundant design synchronously monitor the contact area to ensure the comprehensiveness of the pressure data. At the same time, each set of sensing units transmits data to the central controller integrated in the first assembly 4 through an independent CAN bus branch. The independent bus design ensures the stability of data transmission. Even if one set of units malfunctions, the other units can still continuously provide valid information. The array-redundant pressure sensor 20 captures contact pressure from different angles through multiple sensing units, avoiding the limitations of a single sensor and ensuring a comprehensive reflection of the interaction between the medicinal material and the cutting wheel, providing complete data support for subsequent hardness analysis. The secure installation of the third connector 19 allows the sensor to be precisely aligned with the cutting area, ensuring the accuracy of data acquisition. Independent CAN bus branches transmit data, completely isolating signal interference between different sensing units. Even if one unit fails, the remaining units can still transmit data stably, ensuring that the central controller can always obtain valid information and avoiding adjustment stagnation caused by data interruption. This guarantees the continuous operation capability of the system from the source and lays the foundation for the stable operation of the entire cutting process. The central controller, as the core processing unit, immediately initiates collaborative processing with its built-in dual-core processing units. The main core prioritizes receiving real-time data from the pressure sensor 20, performs feature analysis on the pressure signal using a built-in FFT algorithm, and accurately identifies the hardness characteristics of the medicinal material (such as overall hardness, local hardness differences, etc.). The secondary core retrieves cutting records of similar medicinal materials from encrypted historical processing data, generates initial parameter suggestions adapted to the current medicinal material through trend analysis, and synchronizes them to the main core via the internal data bus. The main core combines the real-time analysis results with the secondary core's suggestions to comprehensively judge the current cutting state and generate preliminary adjustment commands including the rotational speed adjustment direction of the drive component 16 and the feed rate change trends of the first linear drive component 9 and the second linear drive component 14. The main core focuses on real-time data analysis, using FFT algorithms to keenly capture subtle changes in pressure signals and accurately distinguish between the overall hardness and localized differences in softness and hardness of medicinal materials, avoiding adjustment deviations caused by untimely or inaccurate data processing. The secondary core mines historical processing data, transforming past successful experiences into initial parameter suggestions, reducing over-reliance on real-time data and accelerating parameter adaptation. The internal data bus enables efficient synchronization between the two cores, organically integrating real-time monitoring results with historical experience. This ensures that initial adjustment commands not only match the actual characteristics of the current medicinal materials but also draw on mature processing methods from similar materials, significantly improving the scientific rigor and reliability of the commands and providing strong guidance for subsequent precise adjustments. After the adjustment command is generated, the central controller synchronously sends it to the servo drive module and the closed-loop control module (both integrated in the first assembly 4). Upon receiving the command, the servo drive module's integrated adaptive load adjustment unit dynamically adjusts the PWM wave duty cycle based on the predicted cutting resistance value output by the central controller: when it determines that the cutting resistance is increasing, it reduces the output power of the drive component 16 by decreasing the PWM wave duty cycle, thereby reducing the rotational speed of the rotary cutting wheel 18; simultaneously, for the first linear drive component 9 and the second linear drive component 14, it reduces the displacement of the feed mechanism by adjusting the duty cycle of their drive signals, thus matching the changes in the hardness of the medicinal material and maintaining a stable slicing shearing force. Furthermore, the modular plug-in structure of the servo drive module ensures a rapid response of the adjustment unit to commands and also facilitates subsequent algorithm upgrades. The adaptive load adjustment unit dynamically adjusts the PWM wave duty cycle to precisely match the cutting resistance fluctuations caused by changes in the hardness of the medicinal materials. This ensures that the rotational speed of the rotary cutting wheel 18 and the displacement of the feed mechanism are always adapted to the characteristics of the medicinal materials, fundamentally guaranteeing the stability of the slicing shearing force and avoiding material breakage or uneven slice thickness due to uneven force. The coordinated adjustment of the first and second linear drive components achieves "speed-feed" linkage control, making the cutting process more closely match the actual processing needs of the medicinal materials. The modular plug-in structure not only shortens the response time of the adjustment unit to commands and avoids adjustment lag, but also greatly facilitates the upgrading of the adjustment algorithm according to processing needs in the future, without replacing the entire drive module, reducing maintenance costs and extending the service life of the equipment. After receiving basic instructions from the central controller, the closed-loop control module activates its internal disturbance compensation submodule, forming a dual-closed-loop regulation with the real-time feedback from the pressure sensor 20. The disturbance compensation submodule collects real-time data on mechanical vibrations during equipment operation (such as frictional vibrations at the hinge of the telescopic support 24, inertial vibrations from the rotation of the rotary cutting wheel 18), environmental disturbances, and other factors, converting them into quantified disturbance parameters. Combined with the cutting force changes fed back from the pressure sensor 20, it generates a reverse compensation amount—for example, when mechanical resonance causes instantaneous cutting force fluctuations, the compensation submodule outputs a corresponding adjustment signal to counteract the resonance effect. Simultaneously, the central controller adaptively iteratively optimizes the compensation coefficient of the disturbance compensation submodule based on historical compensation effects, making the adjustment more suitable for the processing characteristics of different medicinal materials. The disturbance compensation submodule accurately identifies and quantifies external factors such as mechanical vibration and environmental interference. It generates reverse compensation to counteract the impact of these disturbances on the cutting process, forming a dual closed-loop regulation with the real-time feedback from pressure sensor 20. This significantly reduces the amplitude of instantaneous cutting force fluctuations, ensuring the stability of the cutting state. The central controller's adaptive iterative optimization of the compensation coefficient allows the system to continuously learn the interference characteristics of different medicinal materials during processing. This ensures that the compensation effect continuously improves with the number of processing cycles. Regardless of the hardness or shape of the medicinal material being processed, it maintains a stable cutting force, further improving the uniformity and integrity of the slices and reducing processing defects caused by interference. Throughout the process, the modules continuously interact and dynamically optimize. Pressure sensor 20 constantly monitors pressure changes in the cutting area and transmits the adjusted pressure data back to the central controller via the CAN bus. The main core compares the pressure characteristics before and after adjustment to determine if the current parameters are suitable. If there is still a deviation, it regenerates the adjustment command and sends it to the servo drive module and the closed-loop control module, forming a "monitoring-analysis-adjustment-re-monitoring" cycle mechanism. The secondary core synchronously records the parameters, pressure change curves, and other data for each adjustment, updates the historical database, and visualizes the optimization suggestions through the operation panel 5, allowing operators to monitor the equipment status in real time. The closed-loop cycle of "monitoring-analysis-adjustment-re-monitoring" ensures that the system can promptly detect and correct adjustment deviations. Regardless of changes in the characteristics of the medicinal materials, dynamic adjustments can keep the cutting parameters at their optimal state, avoiding continuous errors caused by one-time adjustments. The secondary core's recording and updating of processing data continuously enriches the historical database, providing more accurate references for the processing of similar medicinal materials in the future, and continuously improving the efficiency and accuracy of parameter adaptation. The visual display of the operation panel 5 allows operators to intuitively grasp the equipment's operating status and optimization suggestions. Effective monitoring of the equipment can be achieved without professional programming knowledge, lowering the operational threshold and improving ease of use and management efficiency. Furthermore, when the tool spacing needs adjustment, the first linear drive assembly 9 drives the first adjusting component 11 via the second connector 10. With the hinged engagement of the telescopic bracket 24 and the mating component 23, the first adjusting component 11 and the second adjusting component 12 adjust the spacing along the sliding track 21 inside the first connector 8 (through the slider 22). During the adjustment process, the pressure sensor 20 synchronously monitors the impact of tool position changes on the cutting force. The central controller combines this data to optimize the adjustment parameters, ensuring the stability of the cutting process after spacing adjustment. The second linear drive assembly 14 drives the third assembly 17 via the flange 15 to further fine-tune the position of the rotary cutting wheel 18. The adjustment amount is also calibrated in real-time by the central controller based on feedback data from the pressure sensor 20. Furthermore, when the tool spacing needs to be adjusted, the first linear drive assembly 9 drives the first adjusting member 11 to move via the second connecting member 10. Under the hinged engagement of the telescopic bracket 24 and the mating member 23, the first adjusting member 11 and the second adjusting member 12 adjust the spacing along the sliding track 21 (with the cooperation of the slider 22) on the inner side of the first connecting member 8. During the adjustment process, the pressure sensor 20 synchronously monitors the influence of the tool position change on the cutting force. The central controller combines this data to optimize the adjustment parameters and ensure the stability of the cutting process after the spacing adjustment. The second linear drive assembly 14 drives the third assembly 17 to move via the flange 15, further fine-tuning the position of the rotary cutting wheel 18. The adjustment amount is also calibrated in real time by the central controller based on the feedback data from the pressure sensor 20.
[0023] This solution uses the first linear drive component 9 to drive the movement of the first adjustment component 11, thereby adjusting the distance between the first adjustment component 11 and the second adjustment component 12 with the cooperation of the telescopic bracket 24. This achieves flexible adjustment of the blade spacing and can accurately adapt the blade spacing according to the shape, size and slicing requirements of different medicinal materials. This greatly improves the equipment's adaptability to diverse processing scenarios and avoids processing limitations caused by fixed blade positions. As a result, it provides a more flexible operating space for slicing various medicinal materials and effectively expands the application range of the equipment.
[0024] This solution forms a dynamic adjustment system with the pressure sensor 20 and the central controller. By collecting the force data of the rotary cutting wheel 18 in real time and analyzing the hardness characteristics of the medicinal material using the FFT algorithm, it can synchronously and precisely adjust the rotation speed of the drive component 16 and the displacement of the first linear drive component 9 and the second linear drive component 14. When encountering medicinal materials with high hardness, the system will automatically reduce the rotation speed and feed rate to maintain a constant slicing shearing force, ensuring the consistency of the slicing process. At the same time, with the cooperation of two sets of rotary cutting wheels 18, one set of rotary cutting wheels 18 pre-treats the surface of the medicinal material, while the other set of rotary cutting wheels 18 completes the main slicing work. This layered cutting mode significantly reduces the load of a single cut, reduces the breakage of the medicinal material due to compression, and improves the integrity and uniformity of the slices.
