[0020] This utility model provides, for example Figures 1-6 The machine shown is an integrated visual recognition and airflow sorting machine for removing impurities from Chinese herbal medicine pieces. It can solve the problems of low efficiency, insufficient accuracy and limited functionality in the existing technology for removing impurities from Chinese herbal medicine pieces.
[0021] refer to Figures 1 to 3As shown, the integrated visual recognition and airflow sorting machine for removing impurities from Chinese herbal medicine pieces includes a chassis 1, a feeding hopper 2, and a Chinese herbal medicine piece collection box 5. The feeding hopper 2, chassis 1, and Chinese herbal medicine piece collection box 5 are distributed from top to bottom. The chassis 1 has an outer shell 3 and a removal collection box 4 on its two sides, respectively. The removal collection box 4 is used to collect impurities. The outer shell 3 is used to install a power fan. The front of the Chinese herbal medicine piece collection box 5 is provided with a side door 8. During operation, Chinese herbal medicine pieces are fed from the feeding hopper 2 and fall into the chassis 1. When the power fan in the outer shell 3 generates airflow, it removes impurities from the Chinese herbal medicine pieces in the chassis 1. Impurities are blown into the removal collection box 4 for collection, while the Chinese herbal medicine pieces are collected in the Chinese herbal medicine piece collection box 5. When the side door 8 is opened, the Chinese herbal medicine pieces collected in the Chinese herbal medicine piece collection box 5 can be taken out.
[0022] refer to Figures 4 to 6 As shown in the figure, a material discharge channel 9 is provided inside the casing 1 in this utility model. The material discharge channel 9 runs through the casing 1 from top to bottom. The Chinese herbal medicine collection box 5 is provided with a first chamber 26, a third chamber 23 and a second chamber 25 in sequence. The upper end of the material discharge channel 9 is connected to the bottom of the feeding hopper 2 and the bottom of the material discharge channel 9 is connected to the upper end of the second chamber 25.
[0023] A cleaning chamber 10 and a first air chamber 17 are respectively provided on the upper two sides of the casing 1. A collection chamber 13 and a second air chamber 20 are respectively provided on the lower two sides of the casing 1. The second air chamber 20 is connected to the material discharge channel 9 through a second air hole 21, and multiple second air holes 21 are provided. The collection chamber 13 is connected to the material discharge channel 9 through a small sieve hole 12, and multiple small sieve holes 12 are provided. The cleaning chamber 10 is connected to the material discharge channel 9 through a cleaning groove 27, and multiple cleaning grooves 27 are provided. The first air chamber 17 is connected to the material discharge channel 9 through a first air hole 16, and multiple first air holes 16 are provided. A first fan 18 and a second fan 19 are provided inside the outer casing 3. The first fan 18 is connected to the interior of the first air chamber 17, and the second fan 19 is connected to the interior of the second air chamber 20. A cleaning channel 11 connected to the cleaning and collection box 4 is provided at the bottom of the cleaning chamber 10. The bottom of the collecting chamber 13 is provided with an inclined channel 14 that communicates with the first chamber 26. The lower side of the discharge channel 9 is also provided with an inclined channel 14 that communicates with the interior of the third chamber 23. An inclined pipe 6 is provided outside the inclined channel 14. A camera 15 is installed on the upper inner wall of the discharge channel 9. The camera 15 can be a high-resolution industrial camera, and the frame rate can generally be set between 30-60fps. It is equipped with an LED light source with a brightness range of 500-2000lm and an angle between 30-60°. It is connected to a commonly used image processing system in the prior art, including an image acquisition card, a computer, and professional image processing software. The image processing software should have functions such as image preprocessing, feature extraction, and classification recognition, and be able to process and analyze the images captured by the camera in real time to accurately identify impurities and substandard products in Chinese herbal medicine slices.
[0024] For example, based on the size of the Chinese herbal medicine slices and the fineness of the impurities, an appropriate image resolution can be selected, generally set between 1024×768 and 4096×3072 pixels, to ensure clear identification of impurities and substandard products. Based on the shape, color, texture, and other characteristics of the Chinese herbal medicine slices and impurities, corresponding feature extraction algorithms and parameters can be set. For instance, for color features, the color space type (e.g., RGB, HSV) and color threshold range can be set; for shape features, thresholds for parameters such as the shape's outline, area, and perimeter can be set. Based on the extracted features, the parameters of the classification and recognition algorithm can be set, such as the kernel function type, parameters C and γ of the Support Vector Machine (SVM); or the network structure, learning rate, and number of iterations of the neural network. By adjusting these parameters, the accuracy and recall of classification and recognition can be improved, thus achieving the screening of Chinese herbal medicine slices.
[0025] The specific process for screening and sorting Chinese medicinal herbs is as follows: The first step involves pouring the Chinese herbal medicine slices into the feed hopper 2. The slices gradually enter the machine housing 1. At this point, the Chinese herbal medicine slices contain large-sized slices, medium-sized slices, small-sized slices, and impurities. These are further subdivided as follows: large-sized slices have a diameter of 5 cm or more; medium-sized slices have a diameter of 3-5 cm; small-sized slices have a diameter of 2-3 cm; and slices with a diameter of less than 2 cm are impurities. After entering the machine housing 1, the Chinese herbal medicine slices first pass between the impurity removal chamber 10 and the first air chamber 17. The first blower 18 is activated to blow air into the first air chamber 17. The airflow enters the material discharge channel 9 through the first air hole 16. The airflow blows the lighter impurities from the side of the Chinese herbal medicine slices into the impurity removal chamber 10 for collection through the impurity removal trough 27. Finally, the impurities are collected in the impurity collection box 4 through the impurity removal channel 11 at the bottom of the impurity removal chamber 10. In the second step, after the Chinese herbal medicine slices have been screened and cleaned, they enter the area between the collection chamber 13 and the second air chamber 20. The second fan 19 is started, and the second fan 19 sends air into the second air chamber 20 and then into the material discharge channel 9 through the second air hole 21. The air in the material discharge channel 9 blows in from the side of the Chinese herbal medicine slices and blows small-sized slices into the collection chamber 13 through the small sieve hole 12. Finally, they fall into the first chamber 26 through the inclined channel 14 for collection. The third step involves the Chinese herbal medicine slices entering the bottom of the feeding channel 9 for further sorting. A perforated sieve plate 22 is movably installed inside the lower end of the feeding channel 9. The side of the perforated sieve plate 22 closest to the third chamber 23 is inclined downwards. An electric vibrator 24 is installed at the bottom of the feeding channel 9. When the electric vibrator 24 is working, it vibrates the perforated sieve plate 22. When the perforated sieve plate 22 vibrates, it can shake the medium-sized slices from the holes on the perforated sieve plate 22 into the second chamber 25 for collection. After the medium-sized slices fall into the second chamber 25, the impurity collection box 4 connected to the third chamber 23 is opened, and the large-sized slices can be discharged into the third chamber 23 for collection, thus realizing the sorting of the three sizes of Chinese herbal medicine slices.
[0026] In actual processing, some Chinese herbal medicine slices are large in size, while others are only available in medium and large sizes. This can be detected by camera 15. Camera 15 is connected to the second fan 19 via a control chip and controlled by existing common control algorithms. When camera 15 detects that there are no small-sized slices in this batch of Chinese herbal medicine slices, it can control the second fan 19 to turn off, reducing energy consumption and making it more energy-efficient. If there are a small number of small-sized slices in the Chinese herbal medicine slices, the second fan 19 can be turned on in time to sort the small-sized slices.
[0027] Furthermore, a rubber baffle 28 is provided in the impurity removal tank 27. The rubber baffle 28 has an arc-shaped plate structure and bends downward to prevent Chinese herbal medicine pieces from falling into the impurity removal tank 27 and causing blockage. A movable gap 29 is provided between the end of the rubber baffle 28 near the inside of the impurity removal tank 27 and the upper inner wall of the impurity removal tank 27. The rubber baffle 28 can be elastically deformed. When Chinese herbal medicine pieces fall onto the upper surface of the rubber baffle 28, they can resist the rubber baffle 28 to bend downward and cause the end of the rubber baffle 28 near the inside of the impurity removal tank 27 to bend upward. This process is repeated to clear the impurities that are easy to block in the impurity removal tank 27 and prevent the impurity removal tank 27 from becoming blocked.
[0028] Furthermore, the first air hole 16 is tilted upward at the end near the material discharge channel 9, which can blow the impurities contained in the Chinese herbal medicine pieces into the bottom of the rubber baffle 28 and into the interior of the impurity removal chamber 10 through the impurity removal groove 27. The structure is reasonably designed, which can not only avoid the Chinese herbal medicine pieces being blown into the impurity removal groove 27 and causing blockage, but also separate the impurities so that after the impurities enter the bottom of the rubber baffle 28, they can be smoothly blown into the impurity removal chamber 10 by the wind.
[0029] It should also be noted that in this utility model, the impurity collection box 4 is installed on the side of the casing 1 by means of hanging. The upper end of the impurity collection box 4 is provided with a hook 7, and the side of the casing 1 is provided with a hanging groove for easy use. Ventilation holes should be provided at the bottom of the impurity collection box 4 and the side of the first chamber 26. The ventilation holes are sealed with breathable cotton to ensure that the wind can carry impurities and small-sized medicinal pieces into the impurity collection box 4 and the first chamber 26 respectively, thus ensuring air circulation.
[0030] A movable baffle 30 is provided at one end of the inclined channel 14 that connects to the material drop channel 9. A connecting shaft 31 is fixedly connected to the upper end of the movable baffle 30. A small motor is embedded inside the housing 1. The small motor is used to drive the connecting shaft 31 to rotate, so that the opening of the inclined channel 14 is opened after the movable baffle 30 rotates. The small motor is a common existing technology and is not shown in the figure.
