[0025] The color sorting device 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0026] like Figures 1-3 As shown, the color sorting device 1 according to an embodiment of the present invention includes a plurality of color sorting devices 10.

[0027] Each color sorting device 10 includes a conveyor belt 100 and a color sorting module 200. The conveyor belt 100 of each color sorting device 10 conveys materials from front to back (as shown by the arrows in the figure in the up-down and front-back directions). Multiple color sorting devices 10 are arranged in the front-back direction. The conveyor belt 100 of the rear color sorting device 10 of two adjacent color sorting devices 10 is adapted to receive the material discharged from the color sorting module 200 of the front color sorting device 10.

[0028] According to the color sorting device 1 of this utility model embodiment, by setting multiple color sorting devices 10, multiple color sorting devices 10 can be used to realize multi-level screening of materials, which is convenient for screening materials with more complex classification requirements such as tea.

[0029] Furthermore, by setting up a conveyor belt 100, materials can be transported from the previous stage color sorting device 10 to the next stage color sorting device 10. Compared with the method of using gravity to move materials in multi-stage color sorters in related technologies, this method can reduce the height difference between color sorting devices 10, facilitate the horizontal arrangement of color sorting devices 10, reduce the overall height of color sorting equipment 1, reduce the installation height required for color sorting equipment 1, prevent the problem of inconvenient maintenance of upper color sorting modules due to excessive height of color sorting equipment 1, and facilitate the maintenance of color sorting equipment 1.

[0030] Furthermore, by arranging multiple color sorting devices 10 in the front-to-back direction, compared with the color sorter in the related art where multi-level color sorting modules are stacked vertically, the multi-level color sorting devices 10 can be arranged in a single layer in the horizontal direction, which can further reduce the overall height of the color sorting device 1, reduce the installation height required for the color sorting device 1, further prevent the problem of inconvenient maintenance of the upper color sorting module due to the excessive height of the color sorting device 1, and further facilitate the maintenance of the color sorting device 1.

[0031] Therefore, the color sorting device 1 according to the present invention has advantages such as easy control of overall height and convenient maintenance.

[0032] The color sorting device 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0033] In some specific embodiments of this utility model, such as Figures 1-3 As shown, the color sorting device 1 according to an embodiment of the present invention includes a plurality of color sorting devices 10.

[0034] Specifically, such as Figure 1 and Figure 2As shown, each color sorting device 10 has a rejection outlet and a retention outlet. The front end of the conveyor belt 100 of the rear color sorting device 10 is adapted to receive the material discharged from the retention outlet of the color sorting module 200 of the preceding color sorting device 10. This allows the material retained after screening by the previous color sorting device 10 to be transported to the next color sorting device 10 for further screening, facilitating multi-stage screening of materials.

[0035] More specifically, such as Figure 1 and Figure 2 As shown, in two adjacent color sorting devices 10, the front end of the conveyor belt 100 of the rear color sorting device 10 is located below the retention outlet of the color sorting module 200 of the front color sorting device 10. This facilitates the rear color sorting device 10 to receive the material discharged from the color sorting module 200 of the front color sorting device 10.

[0036] Figures 1-3 A color sorting device 1 according to some examples of the present invention is shown. For example... Figures 1-3 As shown, the multiple color sorting devices 10 include at least a front-end color sorting device 11 and a rear-end color sorting device 13. The front-end color sorting device 11 is located at the very front of the multiple color sorting devices 10, and its color sorting module 200 is adapted to reject materials with a first characteristic. The rear-end color sorting device 13 is located at the very back of the multiple color sorting devices 10, and its color sorting module 200 is adapted to reject materials that do not conform to the characteristics of the finished product. It should be understood here that those skilled in the art can set "first characteristic," "second characteristic," and "finished product characteristic" according to actual needs. Specifically, rejected materials are discharged through a rejection outlet, and the remaining materials that are not rejected are discharged through a retention outlet. This facilitates the multiple color sorting devices 10 to screen materials with different characteristics, enabling multi-level screening of materials and facilitating the screening of materials with multiple classification requirements.

[0037] Advantageously, such as Figures 1-3 As shown, the multiple color sorting devices 10 also include a secondary color sorting device 12. The secondary color sorting device 12 is located between the front-end color sorting device 11 and the rear-end color sorting device 13, and the color sorting module 200 of the secondary color sorting device 12 is adapted to remove materials with a second characteristic. This further facilitates the screening of materials with different characteristics, facilitates multi-level screening of materials, and facilitates the screening of materials with multiple classification requirements.

[0038] More advantageously, such as Figures 1-3As shown, the color sorting device 1 also includes a first waste sorting device 21 and a second waste sorting device 22. The first waste sorting device 21 is located below the front-end color sorting device 11 and is adapted to receive the material rejected by the front-end color sorting device 11. The first waste sorting device 21 is adapted to select materials having the first characteristic. The second waste sorting device 22 is located below the secondary color sorting device 12 and is adapted to receive the material rejected by the secondary color sorting device 12. The second waste sorting device 22 is adapted to select materials having the second characteristic. Specifically, the first waste sorting device 21 and the second waste sorting device 22 can be a channel-type color sorter or a conveyor-type color sorter. The materials selected by the first waste sorting device 21 and the second waste sorting device 22 can be discharged through their respective retention outlets, and the unselected materials are discharged through the rejection outlet. This allows the first waste sorting device 21 to further screen the waste rejected by the front-end color sorting device 11 based on the first characteristic, and the second waste sorting device 22 to further screen the waste rejected by the secondary color sorting device 12 based on the second characteristic. Specifically, the material first undergoes reverse selection for the first characteristic using the front-end color sorting device 11, then the material rejected by the front-end color sorting device 11 undergoes forward selection for the first characteristic using the first waste sorting device 21. The material retained by the front-end color sorting device 11 undergoes reverse selection for the second characteristic using the secondary color sorting device 12, then the material rejected by the secondary color sorting device 12 undergoes forward selection for the second characteristic using the second waste sorting device 22. Finally, the material retained by the secondary color sorting device 12 undergoes reverse selection using the rear-end color sorting device 13. This sequential reverse and forward selection of corresponding characteristics improves the accuracy and reliability of the screening process, avoiding under-selection or missed selection.

[0039] Specifically, the color sorting device 1 also includes a return material conveying device. The return material conveying device is adapted to transport materials not sorted by the first waste sorting device 21 and the second waste sorting device 22 back to the front end of the conveyor belt 100 of the front-end color sorting device 11. This allows the waste materials not sorted by the first waste sorting device 21 and the second waste sorting device 22 to be sent back to the front-end color sorting device 11 for further multi-stage screening, thereby improving the accuracy and reliability of the screening.

[0040] More specifically, such as Figures 1-3 As shown, the color sorting device 1 also includes a feeding device 30, which is located at the front end of the conveyor belt 100 of the foremost of the multiple color sorting devices 10. Specifically, the return material conveying device is adapted to convey the materials not sorted by the first waste sorting device 21 and the second waste sorting device 22 to the feeding device 30. This facilitates the feeding of materials into the color sorting device 1.

[0041] Furthermore, such as Figure 1 and Figure 2As shown, the color sorting module 200 of each color sorting device 10 is located at the rear end of the conveyor belt 100. This facilitates the subsequent color sorting device 10 to receive the material discharged from the color sorting module 200 of the previous color sorting device 10.

[0042] Optionally, the length-to-height ratio of the color sorting device 1 is greater than or equal to 1.4. This facilitates control over the height of the color sorting device 1, reduces the required installation height, prevents inconvenience in maintaining the upper color sorting module due to excessive height of the color sorting device 1, and makes maintenance of the color sorting device 1 easier.

[0043] Other components and operations of the color sorting device 1 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
