Description

Technical Field

[0001] This utility model relates to the field of medicinal material processing technology, specifically a medicinal material selection machine. Background Technology

[0002] In the processing of traditional Chinese medicinal materials, sorting is necessary to remove impurities and substandard materials, selecting only those that meet the requirements for processing. Manual sorting is inefficient. Traditional color sorters, which sort by color or translucency differences, cannot effectively identify materials without color defects or with minor flaws, limiting the types of materials that can be sorted and resulting in low accuracy. Machine vision technology, however, can quickly acquire image information of raw materials and assess their quality through image processing and analysis algorithms. Compared to manual sorting, machine vision technology offers advantages such as high efficiency, objectivity, and accuracy. Applying it to the sorting process can effectively improve the accuracy and efficiency of medicinal material sorting. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a medicinal material sorting machine. The technical solution adopted is to use a vibrating feeder, a feeding conveyor belt, and a vibrating conveyor to form a medicinal material conveying and vibrating spreading system. The discharge port of the vibrating feeder is equipped with a feeding conveyor belt, and the discharge end of the feeding conveyor belt is equipped with a vibrating conveyor. The medicinal materials are put into the vibrating feeder, and the vibration of the vibrating feeder disperses the medicinal materials and gradually falls onto the feeding conveyor belt. The feeding conveyor belt transports the medicinal materials into the vibrating conveyor. The vibration of the vibrating conveyor ensures that the medicinal materials are completely dispersed and spread out, avoiding the stacking of medicinal materials, which would affect the subsequent image recognition. The discharge port of the vibrating conveyor is connected to a distributing device through a flow guiding device. The distributing device includes a distributing conveyor belt, one end of which is attached to the flow guiding device, and the other end is... An image acquisition device is fixedly installed on the frame of the material distribution device. The medicinal materials, dispersed and spread by the vibrating conveyor, fall smoothly onto the material distribution conveyor belt through the guide device. When the medicinal materials move to the area below the image acquisition device along the material distribution conveyor belt, the image acquisition device takes pictures to obtain the image information of the medicinal materials. A main control computer is installed at the front of the frame of the material distribution device. A material distribution guide trough is installed on the frame of the material distribution device below the discharge end of the material distribution conveyor belt. A blowing device is installed on the frame of the material distribution device above the material distribution guide trough. The blowing nozzle of the blowing device faces the discharge end of the material distribution conveyor belt. A high-quality product discharge conveyor belt and a low-quality product discharge conveyor belt are installed below the material distribution guide trough. The main control computer is electrically connected to the material distribution conveyor belt, the image acquisition device, the blowing device, the high-quality product discharge conveyor belt, and the low-quality product discharge conveyor belt. The image information acquired by the image acquisition device is analyzed by the main control computer to obtain the location information of the substandard medicinal materials. Combined with the conveying speed of the distribution conveyor belt, the position and time at which the substandard medicinal materials leave the distribution conveyor belt can be determined. The main control computer can then control the blowing device to blow at the corresponding position and time, thereby shortening the falling distance of the substandard medicinal materials. The superior medicinal materials that are not blown will maintain their original falling trajectory, so that the substandard and superior medicinal materials fall into different positions in the distribution guide trough and are separated. They are then transported out and collected by the superior discharge conveyor belt and the substandard discharge conveyor belt, respectively.

[0004] As a preferred embodiment of this utility model, a receiving base plate is fixedly connected below the feeding conveyor belt, and a collection tray is placed at the lower end of the receiving base plate. The receiving base plate can catch the medicinal materials that are stuck to the feeding conveyor belt and have not been detached in time, thus preventing the medicinal materials from falling to the ground from below the feeding conveyor belt. The medicinal materials that fall onto the receiving base plate will slide into the collection tray and be collected.

[0005] As a preferred embodiment of this utility model, the vibrating conveyor is a three-stage pneumatic vibrating disc conveyor, in which the vibration frequency of the three-stage pneumatic vibrating disc increases sequentially, so that the medicinal materials can be fully vibrated and spread out during the conveying process.

[0006] In a preferred embodiment of this invention, the guiding device includes a support frame fixedly connected to the end of the material distribution conveyor belt frame. A guiding trough is fixedly connected to the support frame. The guiding trough is inclined, with its upper end located below the discharge port of the vibrating conveyor, and its lower end fixedly connected to an arc-shaped transition plate. The arc-shaped transition plate conforms to the upper surface of the material distribution conveyor belt. Herbs falling from the vibrating conveyor slide down the guiding trough to the arc-shaped transition plate, and then smoothly land on the material distribution conveyor belt, preventing the herbs from bouncing and piling up as they fall.

[0007] In a preferred embodiment of this utility model, a fixed partition plate is fixedly connected to the middle of the bottom of the inner cavity of the material distribution guide trough, dividing the lower opening of the material distribution guide trough into a first discharge port and a second discharge port. A movable partition plate is rotatably connected to the upper part of the fixed partition plate via a pin. Rotation limiting plates are fixedly connected to both ends of the movable partition plate, and limiting slots are provided on the rotation limiting plates. Limiting posts are fixedly connected to the inner sidewalls of both ends of the material distribution guide trough, and the limiting posts are slidably inserted into the limiting slots. The movable partition plate can rotate a certain angle under the restriction of the limiting posts and limiting slots, thereby adjusting the position of the movable partition plate blocking the medicinal materials. The high-quality product discharge conveyor belt is located below the first discharge port, and the substandard product discharge conveyor belt is located below the second discharge port, with the second discharge port close to the discharge end of the material distribution conveyor belt.

[0008] The beneficial effects of this utility model are as follows: This utility model uses a vibrating feeder, a feeding conveyor belt, and a vibrating conveyor to form a medicinal material conveying and vibrating spreading system. During the conveying process, the medicinal materials can be vibrated and dispersed, ensuring complete dispersion and spreading. A flow guiding device ensures that the medicinal materials are stably spread onto the distributing conveyor belt, facilitating image acquisition of all medicinal materials by the image acquisition device, ensuring comprehensive image acquisition and improving sorting accuracy. The feeding conveyor belt has been optimized and modified by adding a receiving base plate and a collection tray, which can collect medicinal materials that adhere to the feeding conveyor belt and fail to detach in time, preventing them from falling to the ground below the feeding conveyor belt. Furthermore, the movable and adjustable partition plate on the distributing guide chute can adjust the position of the obstructing medicinal materials, allowing the angle of the movable partition plate to be adjusted according to the distance and height of different medicinal materials falling from the distributing conveyor belt, thus meeting the distributing needs of different medicinal materials and improving applicability.

Detailed Implementation

[0015] Example 1

[0016] like Figures 1 to 5 As shown, this utility model discloses a medicinal herb selection machine, which uses a vibrating feeder 1, a feeding conveyor belt 2, and a vibrating conveyor 3 to form a medicinal herb conveying and vibrating spreading system. The discharge port of the vibrating feeder 1 is equipped with a feeding conveyor belt 2, and a receiving base plate 201 is fixedly connected below the feeding conveyor belt 2. A collection tray 202 is placed at the lower end of the receiving base plate 201. The receiving base plate 201 can catch the medicinal herbs that are stuck to the feeding conveyor belt 2 and have not been detached in time, preventing the medicinal herbs from falling to the ground below the feeding conveyor belt 2 and falling onto the receiving base plate 201. The herbs will slide into the collection tray 202 and be collected. The discharge end of the feeding conveyor belt 2 is equipped with a vibrating conveyor 3. The herbs are put into the vibrating feeder 1. The vibration of the vibrating feeder 1 disperses the herbs and gradually falls onto the feeding conveyor belt 2. The feeding conveyor belt 2 transports the herbs into the vibrating conveyor 3. The vibrating conveyor 3 is a three-stage pneumatic vibrating disc conveyor. The vibration frequency of the three-stage pneumatic vibrating disc increases sequentially, so that the herbs can be fully vibrated and spread out during the conveying process, avoiding the stacking of herbs and affecting the subsequent image recognition.

[0017] The discharge port of the vibrating conveyor 3 is connected to the distribution conveyor belt 6 on the distribution device 5 via a flow guiding device 4. The flow guiding device 4 includes a support frame 401 fixedly connected to the end of the distribution conveyor belt 6 frame. A flow guiding groove 402 is fixedly connected to the support frame 401. The flow guiding groove 402 is inclined, with its upper end located below the discharge port of the vibrating conveyor 3, and its lower end fixedly connected to an arc-shaped transition plate 403. The arc-shaped transition plate 403 fits against the upper surface of one end of the distribution conveyor belt 6. The medicinal materials falling from the vibrating conveyor 3 will slide down through the flow guiding groove 402 to the arc-shaped transition plate 403, and then smoothly fall onto the distribution conveyor belt 6, preventing the medicinal materials from bouncing up and piling up when they fall. An image acquisition device 7 is fixedly installed on the frame of the material distribution device 5 above the other end of the material distribution conveyor belt 6. The medicinal materials, dispersed and spread by the vibrating conveyor 3, fall smoothly onto the material distribution conveyor belt 6 through the guide device 4. When the medicinal materials move with the material distribution conveyor belt 6 to the image acquisition device 7, the image acquisition device 7 takes a picture to obtain the image information of the medicinal materials. A main control computer 12 is installed at the front of the frame of the material distribution device 5. A material distribution guide trough 8 is installed on the frame of the material distribution device 5 below the discharge end of the material distribution conveyor belt 6. A blowing device 9 is installed on the frame of the material distribution device 5 above the material distribution guide trough 8, with the air blowing nozzle of the blowing device 9 facing the discharge end of the material distribution conveyor belt 6.

[0018] A fixed partition plate 801 is fixedly connected to the middle of the bottom of the inner cavity of the material distribution guide trough 8, dividing the lower opening of the material distribution guide trough 8 into a first discharge port 803 and a second discharge port 804. A movable partition plate 802 is rotatably connected to the upper part of the fixed partition plate 801 via a pin. Rotation limit plates 805 are fixedly connected to both ends of the movable partition plate 802. Limiting slots 806 are formed on the rotation limit plates 805. Limiting posts 807 are fixedly connected to the inner sidewalls of both ends of the material distribution guide trough 8, and the limiting posts 807 are slidably inserted into the limiting slots 806. The high-quality product discharge conveyor belt 10 is located below the first discharge port 803, and the defective product discharge conveyor belt 11 is located below the second discharge port 804. The second discharge port 804 is close to the discharge end of the material distribution conveyor belt 6. The main control computer 12 is electrically connected to the material distribution conveyor belt 6, the image acquisition device 7, the blowing device 9, the high-quality product discharge conveyor belt 10, and the defective product discharge conveyor belt 11.

[0019] The image information acquired by the image acquisition device 7 is analyzed by the main control computer 12 to obtain the location information of the defective medicinal materials. Combined with the conveying speed of the sorting conveyor belt 6, the position and time at which the defective medicinal materials leave the sorting conveyor belt 6 can be determined. The main control computer 12 can then control the blowing device 9 to blow at the corresponding position and time, thereby shortening the falling distance of the defective medicinal materials. The superior medicinal materials that are not blown away maintain their original falling trajectory. Therefore, the defective medicinal materials fall a shorter distance and land at the second discharge port 804 near the sorting conveyor belt 6, and are conveyed and collected on the defective discharge conveyor belt 11. The superior medicinal materials fall a longer distance and land at the first discharge port 803, which is farther from the sorting conveyor belt 6, and are conveyed and collected on the superior discharge conveyor belt 10, thereby completing the sorting of medicinal materials. The movable partition plate 802 can rotate at a certain angle under the restriction of the limiting post 807 and the limiting slot 806, thereby adjusting the position of the movable partition plate 802 blocking the medicinal materials. When sorting different medicinal materials, due to factors such as weight, the distances they travel after being thrown from the sorting conveyor belt 6 and after being sprayed by the blowing device 9 will also vary. Therefore, when high-quality medicinal materials tend to fall into the second discharge port 804 after being thrown from the sorting conveyor belt 6, the movable partition plate 802 can be tilted towards one side of the second discharge port 804, thereby widening the opening width of one side of the first discharge port 803 to facilitate the falling of high-quality medicinal materials. When substandard medicinal materials tend to fall into the first discharge port 803 after being sprayed by the blowing device 9, the movable partition plate 802 can be tilted towards one side of the first discharge port 803, thereby widening the opening width of one side of the second discharge port 804 to facilitate the falling of substandard medicinal materials.
