Description

Technical Field

[0001] This utility model relates to the field of color sorter technology, and more specifically, to a light source illumination structure for a color sorter. Background Technology

[0002] Color sorters are widely used in many fields, such as the food industry for color sorting and grading grains like sesame seeds, peanuts, rice, and soybeans, and some chemical industries for color sorting, grading, or removing impurities from materials like plastic sheets, plastic granules, and salt. Color sorters automatically separate discolored particles from granular materials based on differences in their optical properties using photoelectric technology. Currently, domestically developed photoelectric color sorters are also widely used.

[0003] However, most existing color sorters use the traditional slide-type color sorting lighting method. The color sorting lighting source is mostly installed inside the sorting box. When color sorting is working, the color sorting light source can only illuminate the surface of the material particles. When color sorting materials such as large-volume materials, there will be a large shadow under the material. The existence of the shadow will have a serious adverse effect on the sorting of the material and seriously affect the color sorting effect of the color sorter.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, the purpose of this utility model is to propose a light source illumination structure for a color sorter to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A color sorter light source illumination structure includes: a sorting box and a light source plate disposed in the sorting box, wherein the sorting box is adapted to the light source plate and is provided with a light outlet, and a focusing lens is provided between the light source plate and the light outlet;

[0008] The light source board has a curved structure, and a first lamp bead board and a second lamp bead board are respectively provided on both sides of the light source board. The output beams of the first lamp bead board and the second lamp bead board are distributed in an intersecting manner.

[0009] Furthermore, the cross-sectional end face of the light outlet has an inclined structure.

[0010] Furthermore, the light source plate is movably connected to the sorting box, and the light source plate has assembly corners on both sides.

[0011] Furthermore, the light source board has heat dissipation fins on the side away from the first lamp bead board and the second lamp bead board.

[0012] Furthermore, the light source plate has a focusing section located on the side near the focusing lens and between the first lamp bead plate and the second lamp bead plate.

[0013] The beneficial effects of this utility model are:

[0014] This invention features a cross-distribution of light beams from the first and second LED plates, which, in conjunction with a curved light source plate and a focusing lens, concentrate the light beams towards the light outlet, increasing the illumination brightness and radiation area. The complementary lighting design provides a wide illumination angle for the material, preventing shadows from appearing below the material and improving the color sorting efficiency and accuracy of the color sorter.

[0023] According to an embodiment of the present invention, a light source illumination structure for a color sorter is provided.

[0024] Example 1

[0025] like Figure 1 As shown, Embodiment 1 of the present invention is as follows:

[0026] A color sorter light source illumination structure includes: a sorting box 1 and a light source plate 2 disposed in the sorting box 1. The sorting box 1 is adapted to the light source plate 2 and is provided with a light outlet 5. A focusing lens 9 is provided between the light source plate 2 and the light outlet 5.

Combined with the supplementary lighting design of the first lamp plate 3 and the second lamp plate 4, the angle of illumination on the material is wider, avoiding shadows below the material and improving the color sorting efficiency and accuracy of the color sorter.

[0031] In addition, a focusing part 8 is provided on the side of the light source plate 2 near the focusing lens 9 and located between the first lamp bead plate 3 and the second lamp bead plate 4.

[0032] Specifically, the beams output by the first lamp bead board 3 and the second lamp bead board 4, together with the curved light source board 2 and the focusing lens 9, are focused onto the light outlet 5 to improve the illumination brightness and color sorting accuracy.

[0035] A color sorter light source illumination structure, based on Embodiment 1, further includes: a light source plate 2 movably connected to a sorting box 1, and assembly corners 6 are respectively provided on both sides of the light source plate 2.

[0036] Specifically, by adjusting the assembly angle of the light source board 2, the output beam angle of the first lamp bead board 3 and the second lamp bead board 4 can be adjusted, thereby adapting to color sorting assembly requirements and having wide adaptability.

[0037] In summary, the following effects can be achieved by utilizing the above-described technical solution of this utility model:
