Description

Technical Field

[0001] This utility model relates to the field of Chinese medicinal material processing, specifically to an intelligent sorting device for medicinal materials. Background Technology

[0002] In the field of traditional Chinese medicine (TCM) processing, the quality sorting of medicinal materials is a crucial step in ensuring the precision of subsequent processing, the stability of efficacy, and the standardization of products. During the drying and storage processes, sliced ​​or diced TCM materials are prone to contamination by impurities, damaged materials, and inferior products of uneven size. Furthermore, manual sorting suffers from low efficiency, strong subjectivity, and difficulty in achieving consistent sorting accuracy, making it unsuitable for large-scale production. Therefore, intelligent sorting devices, with their integrated process of automated conveying, visual recognition and detection, and pneumatic rejection, have become core equipment in the TCM processing industry. Their ability to achieve orderly arrangement and accurate detection of medicinal materials directly determines sorting efficiency and the quality of qualified materials.

[0003] Existing intelligent sorting devices for medicinal materials mainly consist of a mounting frame, a vibrating plate, a conveyor belt, a visual recognition device, and a pneumatic rejection device. The vibrating plate disperses the medicinal materials, which then fall directly onto the conveyor belt. The conveyor belt transports the materials to the visual recognition device for inspection, and the pneumatic device then rejects defective products. However, sheet-like and strip-shaped medicinal materials tend to overlap and accumulate on the conveyor belt, making it difficult for the visual recognition device to clearly identify the complete shape of individual medicinal materials. This leads to frequent misjudgments (such as missing damaged pieces or mistakenly rejecting qualified pieces), significantly reducing sorting accuracy. At the same time, uneven distribution of medicinal materials makes it difficult for the pneumatic rejection device to accurately locate defective products, and some impurities or damaged pieces cannot be effectively removed, further reducing the sorting pass rate. This makes it difficult to meet the high-efficiency and high-quality sorting requirements for sheet-like and strip-shaped medicinal materials. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an intelligent sorting device for medicinal materials to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a smart sorting device for medicinal materials, including a mounting frame and a vibrating plate located on one side thereon. A conveyor belt located below the discharge position of the vibrating plate is mounted on the mounting frame, and a visual recognition device located above the discharge end of the conveyor belt is mounted on the mounting frame. A pneumatic rejection device is mounted on the visual recognition device, and a waste frame is provided below the pneumatic rejection device. A medicinal material collection box for receiving good medicinal materials is provided outside the waste frame. The mounting frame is equipped with a diversion mechanism located above the conveyor belt. The mechanism includes a positioning frame mounted on the mounting frame, and a docking frame mounted on the positioning frame. The docking frame has an L-shaped cross-section and beveled bottom corners. Multiple equally spaced distribution plates are installed on the outer wall of the docking frame, forming a medicinal material channel between the distribution plates. The bottom of the distribution plates is located above the conveyor belt but does not contact it.

[0006] By adopting the above technical solution, the material distribution plate of the diversion mechanism forms a channel for medicinal materials, and the angled design guides the orderly arrangement of medicinal materials to avoid overlapping and accumulation. After the visual recognition device accurately detects the materials, the pneumatic rejection device removes the unqualified products, and the waste frame and collection box are classified and received, which greatly improves the sorting accuracy and efficiency and is suitable for sorting flake and strip medicinal materials.

[0007] Furthermore, the two ends of the positioning frame are threadedly connected to the top of the mounting frame by bolts. The positioning frame has multiple sets of docking slots. The outer wall of the docking frame without the material distribution plate is equipped with docking blocks that are slidably connected to the docking slots, and the top width of the docking block is greater than its bottom width.

[0008] By adopting the above technical solution, the positioning frame and the mounting frame are bolted securely connected, the docking block and the docking groove slide together, and the docking block is designed to prevent it from falling out. This not only makes it easy to adjust the position of the docking frame to adapt to different medicinal materials, but also ensures the stable operation of the diversion mechanism and avoids displacement from affecting the sorting.

[0009] Furthermore, a screw is fixedly installed on the outer wall of the docking frame without the material distribution plate, and a through hole corresponding to the screw is opened through the positioning frame, and the screw is tightened with a nut after passing through the through hole.

[0010] By adopting the above technical solution, the screw is locked with a nut after passing through the through hole of the positioning frame, which can quickly fix or loosen the docking frame, making it easy to disassemble and replace different specifications of material sorting plates, adapting to the sorting of multiple sizes of medicinal materials, and the operation is simple and reliable, reducing equipment adjustment time.

[0011] Furthermore, the outer corners of the material distribution plate are all designed with bevels. A drive shaft is rotatably mounted on the material distribution plate. Multiple sets of undulating strips located in the herb channel are installed on the drive shaft, and the undulating strips correspond one-to-one with the herb channel to ensure that the herbs can move smoothly between the conveyor belt and the docking frame.

[0012] By adopting the above technical solution, the angled distribution plate prevents scratching of the medicinal materials, and the drive shaft drives the pulsating strip to rotate, pushing the medicinal materials smoothly into the channel, avoiding jamming and accumulation, ensuring that the medicinal materials are transported to the testing station in an orderly manner, and improving the continuity and stability of sorting.

[0013] Furthermore, drive wheels are fixedly installed at both ends of the drive shaft, with the bottom end of the drive wheel in contact with the top surface of the conveyor belt, and the drive wheel is located outside the two outermost material distribution plates.

[0014] By adopting the above technical solution, the drive wheel rotates synchronously with the conveyor belt, eliminating the need for additional power to drive the drive shaft and saving energy. The drive wheel is located next to the outer distribution plate, which does not occupy the space of the medicinal material channel, ensuring that the medicinal material is transported without interference, simplifying the structure and reducing maintenance costs.

[0015] Furthermore, the docking frame is provided with a movable groove corresponding to the wave bar, the outer end of the wave bar is made of rubber material, and the outer corner of the wave bar is designed with an arc-shaped rounded corner.

[0016] By adopting the above technical solution, the movable groove allows the undulating bar to rotate flexibly. The undulating bar, made of rubber and with a rounded corner design, can both push the medicinal materials and avoid scratching them, thus protecting the appearance of the medicinal materials. At the same time, it is suitable for medicinal materials with different hardness, improving the versatility of the device.

[0017] Furthermore, the inner wall of the mounting frame is detachably mounted with a stop block that is attached to the outer end of the outermost material distribution plate by bolts. The outer end face of the stop block is designed with a bevel, and the width of the inner end of the stop block is greater than the distance between the material distribution plate and the inner wall of the mounting frame.

[0018] By adopting the above technical solution, the inclined surface of the baffle guides the medicinal materials into the channel, preventing them from entering the transmission wheel area; the detachable design facilitates replacement and maintenance, and the inner end width is adapted to the spacing between the material distribution plate and the mounting frame, ensuring orderly conveying of medicinal materials, reducing sorting failures, and ensuring efficient operation of the equipment.

[0019] In summary, the present invention has the following main advantages: This invention achieves efficient and accurate sorting, adapting to the needs of large-scale processing of sliced ​​and strip-shaped medicinal materials. The material distribution plate of the diversion mechanism forms multiple channels for medicinal materials, which, together with the vibration strip, promote the orderly arrangement of medicinal materials and avoid overlapping and accumulation. The visual recognition device accurately detects the quality of medicinal materials, and the pneumatic rejection device quickly removes unqualified products. The docking frame is detachable and replaceable, and the design of the blocks and bevels guides the smooth transport of medicinal materials, which not only improves the sorting accuracy and efficiency, but also reduces the misjudgment rate and ensures the quality of qualified medicinal materials.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] A kind of intelligent sorting device for medicinal materials, such as Figure 1 - Figure 5 As shown, it includes components such as mounting frame 1, vibratory feeder 2, conveyor belt 3, diversion mechanism 4, visual recognition device 5, pneumatic rejection device 6, medicinal material collection box 7, and waste material frame 8; The mounting frame 1 is the core support frame of the sorting device, used to install various functional components. The top is equipped with a conveyor belt 3, a diversion mechanism 4, and a visual recognition device 5. The inner wall of the mounting frame 1 is detachably installed with a stop block 432 by bolts. The outer end face of the stop block 432 is designed with a bevel, and the inner width of the stop block 432 is greater than the distance between the material distribution plate 42 and the inner wall of the mounting frame 1. This is used to guide the medicinal materials into the medicinal material channel in an orderly manner and prevent the medicinal materials from entering the position of the transmission wheel 43.

[0025] The vibratory plate 2 is located on one side of the mounting frame 1 and is used to disperse the medicinal materials to be sorted. Its discharge position corresponds to the feed end of the conveyor belt 3. The dispersed medicinal materials can fall evenly onto the surface of the conveyor belt 3.

[0026] The conveyor belt 3 is installed on the mounting frame 1, located below the discharge position of the vibrating plate 2, and is used to transport the medicinal materials to each workstation (the operating principle of the conveyor belt 3 is not described in detail here). The top surface of the conveyor belt 3 is in contact with the bottom end of the drive wheel 43, and can drive the drive wheel 43 to rotate synchronously during operation.

[0027] The diversion mechanism 4 is installed on the mounting frame 1, located above the conveyor belt 3, and is used to divert and arrange the medicinal materials. It includes a positioning frame 40, a docking frame 41, a material distribution plate 42, a transmission wheel 43, a transmission shaft 430, a wave bar 431, a docking block 44, a docking groove 45, and a screw 46. The positioning frame 40 is connected to the top of the mounting frame 1 by bolts at both ends. The outer wall of the positioning frame 40 has multiple sets of docking grooves 45 and through holes corresponding to the screw 46 for installation with the docking frame 41. The docking grooves 45 are slidably connected to the docking block 44 to provide support and sliding guidance for the docking frame 41. The docking frame 41 has an L-shaped cross-section and beveled bottom corners. The outer wall of the non-distribution plate 42 is fitted with a docking block 44 and a screw 46. The top width of the docking block 44 is greater than the bottom width to prevent it from coming out of the docking groove 45. The screw 46 passes through the through hole of the positioning frame 40 and is tightened with a nut to fix the docking frame 41 to the positioning frame 40. The docking frame 41 has a movable groove corresponding to the wave bar 431 for the wave bar 431 to rotate. Multiple material distribution plates 42 are installed on the outer wall of the docking frame 41, distributed at equal intervals, forming a channel for medicinal materials; the outer corners of the material distribution plates 42 are all designed with beveled angles to avoid scratching the medicinal materials; the outermost two material distribution plates 42 are provided with drive wheels 43, and drive shafts 430 are rotatably installed on the material distribution plates 42. The drive wheel 43 is fixedly installed at both ends of the drive shaft 430, with its bottom end in contact with the top surface of the conveyor belt 3, and can rotate synchronously with the operation of the conveyor belt 3; multiple sets of undulating bars 431 are installed on the drive shaft 430, and the undulating bars 431 correspond one-to-one with the medicinal material channel. The outer end is made of rubber material, and the corners are designed with rounded corners to push the medicinal materials to move smoothly between the conveyor belt 3 and the docking frame 41, avoiding jamming.

[0028] The visual recognition device 5 is mounted on the mounting frame 1, located above the discharge end of the conveyor belt 3, and is used to inspect the quality of each medicinal material and distinguish between qualified and unqualified materials. A pneumatic rejection device 6 is installed on the visual recognition device 5. The pneumatic rejection device 6 receives signals from the visual recognition device 5 and, upon activation, blows unqualified medicinal materials into the waste material frame 8. The visual recognition device 5 and the pneumatic rejection device 6 are the same as commonly used visual recognition devices and pneumatic rejection devices in the prior art, and are therefore existing technologies in this field, and will not be described in detail here.

[0029] Waste frame 8 is located below pneumatic rejection device 6 and is used to receive unqualified medicinal materials; medicinal material collection box 7 is located outside waste frame 8 and is used to receive qualified medicinal materials. Qualified medicinal materials can fall into it under the conveying force of conveyor belt 3 and their own inertia.

[0030] Through the coordinated operation of the above components, the medicinal materials to be sorted are sent to the vibrating plate 2 via the conveyor during use. The vibrating plate 2 disperses the medicinal materials through vibration, and the dispersed medicinal materials fall evenly onto the surface of the conveyor belt 3 on the mounting frame 1. After the conveyor belt 3 is started, it runs at high speed, conveying the medicinal materials towards the visual recognition device 5. During this process, the medicinal materials first pass through the diversion mechanism 4 above the conveyor belt 3. The positioning frame 40 of the diversion mechanism 4 is fixed to the top of the mounting frame 1 by bolts. The docking frame 41 is slidably connected to the docking groove 45 of the positioning frame 40 by the docking block 44 and locked by the screw 46 and the nut. The multiple groups of material distribution plates 42 on the docking frame 41 are evenly distributed to form multiple medicinal material channels. The medicinal materials enter the medicinal material channels under the drive of the conveyor belt 3 to achieve diversion. At the same time, when the conveyor belt 3 runs, it is in contact with the top surface of the transmission wheel 43, which drives the transmission wheel 43 to rotate synchronously. Then, the transmission shaft 430 drives multiple groups of undulating bars 431 to rotate. The undulating bars 431 correspond one-to-one with the medicinal material channels, pushing the medicinal materials smoothly into the space between the docking frame 41 and the conveyor belt 3, avoiding the medicinal materials from getting stuck. The stop block 432 is in contact with the outer end of the outermost material distribution plate 42. Its inclined design guides the medicinal materials to enter the medicinal material channels in an orderly manner and prevents the medicinal materials from entering the installation position of the transmission wheel 43. After being sorted, the medicinal materials are neatly arranged and moved to the area below the visual recognition device 5 by the conveyor belt 3. The visual recognition device 5 inspects each medicinal material to distinguish between qualified and unqualified materials. When an unqualified medicinal material is detected, the visual recognition device 5 sends a signal to the pneumatic rejection device 6 at the corresponding position. When the unqualified medicinal material moves to the discharge end of the conveyor belt 3, the pneumatic rejection device 6 is activated and blows it into the waste frame 8 below. Qualified medicinal materials fall directly into the medicinal material collection box 7 under the conveying force of the conveyor belt 3 and their own inertia, completing the sorting process. When it is necessary to sort medicinal materials of another size, first unscrew the fixing bolts of the stop block 432 to remove it and remove its obstruction of the sorting plate 42. Then unscrew the nut at the end of the screw 46. At this time, the fixing between the docking frame 41 and the positioning frame 40 is released. Then the docking frame 41 can be pushed towards the vibrating plate 2. Since the top plane of the docking frame 41 is higher than the top plane of the positioning frame 40, it is convenient for the user to push the docking frame 41. During the sliding process of the docking frame 41, the screw 46 will move along the through hole of the positioning frame 40. At the same time, the docking block 44 will slide in the docking groove 45 to avoid the sorting plate 42 scratching the surface of the conveyor belt 3 over a large area during the sliding process. Until the screw 46 separates from the positioning frame 40, the docking frame 41 and the sorting plate 42 can be removed. Replace the docking frame 41 (including the corresponding spacing and thickness of the dividing plate 42) with the new medicinal material size. First, align the screw 46 of the docking frame 41 with the through hole and push the screw 46 into the through hole. Then, the docking block 44 will slide into the docking groove 45. The docking groove 45 will cooperate with the docking block 44 to support the docking frame 41. After the docking frame 41 is in contact with the positioning frame 40, tighten the nut to fix it. Then install the back stop block 432 to complete the specification adaptation adjustment.
