Description

Technical Field

[0001] This utility model belongs to the technical field of Chinese medicinal material processing equipment, and relates to a high-efficiency cutting device for Chinese medicinal materials. Background Technology

[0002] Cutting medicinal herbs is a crucial step in the processing of traditional Chinese medicine, and its quality directly affects the efficacy, storage stability, and subsequent processing efficiency of the herbs. Currently, medicinal herbs are mainly cut manually and using traditional mechanical methods.

[0003] Manual cutting relies on the operator's experience and physical strength, resulting in high labor intensity, low cutting efficiency, and difficulty in ensuring consistent cutting dimensions. This is especially true for batch processing of Chinese medicinal materials, which can easily lead to uneven thickness and length, affecting the quality of the materials.

[0004] Traditional mechanical cutting devices are mostly fixed cutting structures, lacking precise feeding and positioning mechanisms. This makes it easy for medicinal herbs to shift during transport, leading to significant cutting errors. Furthermore, the cutting parameters of the cutting blade assembly are inconvenient to adjust, failing to flexibly adapt cutting speed and thickness to different types and hardnesses of medicinal herbs, resulting in poor versatility. In addition, traditional devices have low automation levels, requiring frequent manual intervention in the feeding and cutting processes, further limiting processing efficiency and posing certain safety hazards.

[0005] With the large-scale development of the traditional Chinese medicine industry, higher requirements have been placed on the efficiency, precision and automation of the cutting of Chinese medicinal materials. Existing technologies are no longer able to meet actual production needs. Therefore, in order to solve the above-mentioned technical problems, the technical solution of this application has been proposed. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency cutting device for Chinese medicinal herbs, thus solving the aforementioned technical problems. The technical solution adopted by this invention is as follows: A high-efficiency cutting device for Chinese medicinal materials includes a base, a conveying mechanism, a cutting mechanism, and a control system; The conveying mechanism includes a conveyor frame, a drive roller, a driven roller, a conveyor belt, and a conveyor motor. The conveyor frame is fixed on the base. The drive roller and the driven roller are rotatably connected to both ends of the conveyor frame. The conveyor belt is sleeved on the drive roller and the driven roller. The conveyor motor is fixed on the conveyor frame and its output shaft is connected to the drive roller for transmission. The cutting mechanism includes a cutting frame, a cutting blade assembly, a lifting cylinder, and a cutting motor. The cutting frame is fixed on the base and located above the output end of the conveying mechanism. The lifting cylinder is fixed on the top of the cutting frame. The piston rod end of the lifting cylinder is connected to a mounting plate. The cutting motor is fixed on the mounting plate. The cutting blade assembly is connected to the output shaft of the cutting motor. The control system includes a controller and a sensor group. The sensor group includes a position sensor for detecting the position of the Chinese medicinal materials and a thickness sensor for detecting the cutting thickness. The position sensor is fixed on the side of the conveyor frame near the cutting mechanism, and the thickness sensor is fixed on the cutting frame. The controller is electrically connected to the conveyor motor, the lifting cylinder, the cutting motor, and the sensor group.

[0007] The working principle of this invention is as follows: During operation, the medicinal herbs are first placed onto the conveyor belt through the feed hopper. The conveyor motor drives the drive roller to rotate, causing the conveyor belt to transport the herbs towards the cutting mechanism. When the position sensor detects that the herbs have reached the cutting position, it transmits a signal to the controller. The controller then controls the conveyor motor to stop conveying and simultaneously controls the lifting cylinder to lower the cutting blade assembly. The cutting motor then drives the cutting blade assembly to rotate and cut the medicinal herbs.

[0008] A thickness sensor detects the cutting thickness and feeds the information back to the controller, allowing the controller to adjust the cutting parameters. After cutting, a lifting cylinder raises the cutting blade assembly, while the conveyor motor continues to operate, transporting the cut medicinal herbs to the receiving trough. Simultaneously, new medicinal herbs are transported to the cutting position, and this cycle repeats continuously.

[0009] Furthermore, the conveyor belt surface is provided with anti-slip protrusions, which are evenly distributed along the length of the conveyor belt. This design primarily aims to enhance the friction between the medicinal herbs and the conveyor belt, preventing the herbs from sliding or shifting during transport due to belt movement or their own weight, thus ensuring the herbs are stably transported to the cutting position. Especially for herbs with smooth surfaces or irregular shapes, the anti-slip protrusions effectively improve the reliability of transport and guarantee the accuracy of subsequent cutting processes. Simultaneously, the evenly distributed structure ensures uniform friction distribution, preventing uneven stress on the herbs and resulting positional deviations.

[0010] Furthermore, the cutting blade assembly includes a blade shaft and at least two cutting blades, which are fixedly spaced on the blade shaft. The blade shaft is connected to the output shaft of the cutting motor via a coupling. Clearly, the cutting blade assembly consists of a blade shaft and at least two cutting blades, with the blades fixedly spaced on the blade shaft, and the blade shaft connected to the output shaft of the cutting motor via a coupling. The design using multiple cutting blades enables the production of multiple slices or segments of medicinal herbs in a single cutting operation, significantly improving cutting efficiency and making it suitable for batch processing needs. The coupling serves to buffer, reduce vibration, and compensate for the relative displacement of the two shafts, ensuring that the power from the cutting motor is stably and efficiently transmitted to the blade shaft, making the cutting blade assembly operate more smoothly and reducing cutting errors caused by unstable power transmission.

[0011] Furthermore, an adjusting shim is provided between the cutting blade and the cutter shaft. This adjusting shim is used to adjust the spacing between adjacent cutting blades. The core purpose of this design is to enable the cutting device to adapt to the different cutting thickness requirements of various Chinese medicinal materials. By increasing or decreasing the number of adjusting shims and changing their thickness, the distance between adjacent blades can be flexibly adjusted, thereby cutting Chinese medicinal materials into slices or segments of different thicknesses. For example, the shim thickness can be reduced when cutting thinner materials and increased when cutting thicker materials, greatly improving the versatility and practicality of the device.

[0012] Furthermore, the cutting frame is equipped with a guide rod, and the mounting plate has a guide hole adapted to the guide rod. The guide rod passes through the guide hole and is slidably connected to the mounting plate. The guide rod and guide hole's mating structure primarily serves a guiding and limiting function. During the lifting process of the lifting cylinder driving the mounting plate and cutting blade assembly to rise and fall, it ensures that the cutting blade assembly always moves vertically, avoiding lateral deviation or swaying. This not only ensures the accuracy of the cutting position and reduces cutting errors but also reduces vibration during the movement of the cutting blade assembly, extends the service life of the cutting blade assembly and lifting cylinder, and improves the overall stability of the device.

[0013] Furthermore, a receiving trough is provided on the base below the cutting mechanism. This receiving trough is detachably connected to the base. Its main function is to collect the cut medicinal herbs, preventing them from scattering onto the base or ground, facilitating subsequent collection, sorting, and handling. The detachable design allows for easy cleaning and maintenance. When the collected herbs reach a certain amount, the trough can be detached and the herbs poured out, making operation simple and convenient. Additionally, if the receiving trough is damaged, it can be quickly replaced without affecting the normal operation of the device.

[0014] Furthermore, the sensor group also includes a tension sensor for detecting conveyor belt tension. This tension sensor is fixed to the conveyor frame and in contact with the driven roller. The tension sensor is electrically connected to the controller. The addition of this tension sensor to the sensor group, which is fixed to the conveyor frame, in contact with the driven roller, and electrically connected to the controller, allows for real-time monitoring of the conveyor belt tension. When the conveyor belt becomes loose due to prolonged use or experiences abnormal tension due to uneven stress, the sensor transmits a signal to the controller. The controller can adjust the conveyor belt tension in a timely manner according to a preset tension range by adjusting the output of the conveyor motor or other related components. This ensures the conveyor belt is always at a suitable tension, preventing slippage due to insufficient tension affecting conveying efficiency, or excessive wear on the conveyor belt and related components due to excessive tension, thus extending the conveyor belt's service life and ensuring stable operation of the conveying mechanism.

[0015] Furthermore: the input end of the conveying mechanism is equipped with a feeding hopper, which is fixed on the conveyor frame. The bottom of the feeding hopper has a discharge port adapted to the conveyor belt. The feeding hopper facilitates centralized feeding of medicinal herbs by operators, preventing them from scattering outside the conveyor belt when directly fed, thus reducing material waste and subsequent cleaning. The discharge port at the bottom, adapted to the conveyor belt, guides the medicinal herbs to fall onto the conveyor belt in an orderly manner, ensuring a more even distribution and facilitating subsequent conveying and cutting processes. It also controls the feeding speed, preventing blockages caused by excessive feeding at once, and ensuring continuous and efficient operation of the device.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. A high-efficiency cutting device for Chinese medicinal materials, which realizes continuous conveying and batch cutting of Chinese medicinal materials through the coordinated and automated operation of the conveying mechanism and the cutting mechanism, without the need for manual intervention in the feeding and cutting process. Compared with manual cutting, the efficiency is increased by 3-5 times, and 50-80 kg of Chinese medicinal materials can be processed per hour, meeting the needs of large-scale production. 2. In this utility model, the position sensor is used to accurately locate the cutting position of Chinese medicinal materials, and the thickness sensor is used to monitor the cutting size in real time. The cutting parameters are adjusted by the control system to keep the cutting accuracy error within ±0.5mm, ensuring that the size of the Chinese medicinal material slices and segments after cutting is uniform and consistent, thereby improving the quality of the medicinal materials. 3. In this utility model, the cutting blade assembly can flexibly adjust the spacing between adjacent blades by adjusting the shims to adapt to the cutting thickness requirements of different Chinese medicinal materials; the conveyor belt adopts an anti-slip design and can be selected with different materials, which is suitable for cutting a variety of Chinese medicinal materials such as rhizomes and vines, and has strong versatility; 4. In this utility model, the automated conveying, positioning and cutting process reduces manual operation. Operators only need to load materials and monitor the equipment, which significantly reduces labor intensity and avoids the safety hazards of manual contact with the cutting area. 5. In this utility model, the cutting mechanism is equipped with a sliding fit structure between the guide rod and the mounting plate, which improves the stability of the lifting and lowering movement of the cutting blade assembly and reduces vibration and offset during the cutting process; the tension sensor monitors the tension of the conveyor belt in real time and adjusts it through the controller, ensuring the smoothness of the conveying process and extending the service life of the equipment; 6.
