At the same time, by adjusting the parameters of the vision cameras and the supplementary light lamps, it can adapt to the sorting requirements of different materials and colors.

[0008] Further, a plurality of material guiding grooves are opened at the upper end of the inclined plate.

[0009] Through the above solution, the material guiding grooves can divert the materials conveyed from the hopper and the discharge roller, ensuring that each material particle can accurately fall into the predetermined position.

[0031] Please refer to Figure 1 , Figure 2 and Figure 3, A color sorter in this embodiment includes an inclined plate 1. One side of the upper end of the inclined plate 1 is fixedly connected to a hopper 2. The inner bottom end of the hopper 2 is rotatably connected to a discharge roller 3. A plurality of material distribution grooves 4 are arranged in an annular array on the outer wall of the discharge roller 3. A discharge port 5 is opened at the bottom end of the hopper 2. A light-shielding plate 6 is fixedly connected to the upper end of the inclined plate 1. A plurality of vision cameras 7 arranged in a straight array penetrate through the upper end of the light-shielding plate 6. Through the design of the discharge roller 3 and the material distribution grooves 4 in the hopper 2, this device can evenly and continuously separate and convey the materials onto the inclined plate 1, and cooperate with the vision cameras 7 to perform high-speed and accurate color recognition, improving the sorting efficiency. On both sides inside the light-shielding plate 6, supplementary light lamps 8 are fixedly connected. The supplementary light lamps 8 provide uniform and sufficient light to ensure that the vision cameras 7 can capture clear material images, thereby improving the screening accuracy.

[0032] Please refer to Figure 2 , Figure 3 and Figure 4 , A plurality of material guiding grooves 9 are opened at the upper end of the inclined plate 1. The material guiding grooves 9 can divert the materials conveyed from the hopper 2 and the discharge roller 3 to ensure that each material particle can accurately fall into a predetermined position. This can avoid the accumulation or mutual interference of materials on the inclined plate 1, thereby improving the sorting accuracy and efficiency. One side of the hopper 2 is fixedly connected to a motor 10. The output end of the motor 10 passes through one end of the hopper 2 and is fixedly connected to the discharge roller 3 through a coupling. The motor 10 serves as a power source and directly drives the rotation of the discharge roller 3 through the coupling. This direct drive method reduces the transmission links, improves the energy transfer efficiency, and at the same time reduces the failure rate, making the entire sorting process more stable and reliable. By controlling the rotation speed of the motor 10, the rotation speed of the discharge roller 3 can be precisely adjusted, thereby controlling the discharge speed and sorting speed of the materials.

Solenoid valves 16 are fixedly connected to the outside of the plurality of air outlet pipes 15. Flexible hoses 17 are fixedly connected to one end of the plurality of air outlet pipes 15 far away from the air tank 14. By adjusting the opening and closing states of the solenoid valves 16, the flow conditions of materials in different areas can be controlled. This helps to separate the materials to different positions on the inclined plate 1 according to color differences or other characteristics, facilitating subsequent collection and processing.

The other sides of the plurality of flexible hoses 17 far away from the air outlet pipes 15 are fixedly connected to the pneumatic push rods 19. Since the flexible hoses 17 are directly connected to the pneumatic push rods 19, when the air tank 14 releases air flow through the air outlet pipes 15 and the flexible hoses 17, the pneumatic push rods 19 can quickly respond and make corresponding movements.

[0034] In this embodiment, for the color sorter, through the design of the discharging roller 3 and the material distribution groove 4 in the hopper 2, the device can evenly and continuously separate and convey the materials onto the inclined plate 1, and cooperate with the vision camera 7 to perform high-speed and accurate color recognition, improving the sorting efficiency. A plurality of vision cameras 7 are arranged in a linear array, expanding the field of view range, enabling more materials to be observed and recognized simultaneously. At the same time, the supplementary light lamp 8 provides uniform and sufficient light to ensure that the vision camera 7 can capture clear material images, thereby improving the screening accuracy. The operation of the color sorter is relatively simple. Just put the materials into the hopper 2, and the device can automatically complete the sorting process. At the same time, by adjusting the parameters of the vision camera 7 and the supplementary light lamp 8, it can adapt to the sorting requirements of different materials and colors.

At the same time, by adjusting the parameters of the vision camera 7 and the supplementary light lamp 8, it can adapt to the sorting requirements of different materials and colors.

[0035] It should be noted that the material distribution groove 4 corresponds to the material guiding groove 9.

[0036] The working principle of the above embodiment is as follows:

[0037] First, place the material to be sorted into the hopper 2. At this time, the motor 10 starts to work, driving the discharge roller 3 to rotate at the bottom end inside the hopper 2. Since a plurality of material distribution grooves 4 are arranged in an annular array on the outer wall of the discharge roller 3, as the discharge roller 3 rotates, these material distribution grooves 4 can evenly and continuously separate the material from the hopper 2 and convey it to the inclined plate 1. After the material comes out of the material distribution grooves 4, it will fall into the material guiding grooves 9 opened on the inclined plate 1. The design of these material guiding grooves 9 can divert the material, ensuring that each material particle can accurately fall into the predetermined position, avoiding the accumulation or mutual interference of the material on the inclined plate 1. A plurality of vision cameras 7 at the upper end of the light shielding plate 6 start to work. These vision cameras 7 are arranged in a linear array, which can expand the field of view, enabling more materials to be observed and identified simultaneously. The vision cameras 7 capture the images of the materials on the inclined plate 1 and identify materials of different colors through image processing technology. In order to ensure that the vision cameras 7 can capture clear material images, the fill light 8 provides uniform and sufficient light. The fill light 8 is installed on both sides inside the light shielding plate 6 to provide sufficient illumination for the vision cameras 7 and improve the screening accuracy. When the vision cameras 7 identify the colors of the materials, according to the preset sorting rules, the control system will decide which materials need to be removed. At this time, the control system will control the solenoid valve 16 at the corresponding position to open, so that the air flow in the air tank 14 enters the corresponding pneumatic push rod 19 through the air outlet pipe 15 and the hose 17. After receiving the air flow, the pneumatic push rod 19 will perform a telescopic movement, pushing the second fixed plate 20 fixedly connected to it to move. Since the second fixed plate 20 is connected to one side of the bottom end of the baffle plate 12, the baffle plate 12 will slide in the chute 11, thereby changing the opening and closing states of the discharge port 21. When the discharge port 21 is opened, the materials at the corresponding position will fall into the waste box 22 through the discharge port 21, realizing the removal of unqualified materials. The qualified materials will continue to slide down along the inclined plate 1 and finally enter the collection box 23 through the material guiding grooves 9. Users can adjust the parameters of the vision cameras 7 and the fill light 8 according to the characteristics and sorting requirements of the materials to optimize the sorting effect.
