[0035] Example

[0036] like Figure 1 As shown, the utility model proposes a double infrared color sorting machine, including a frame and an electric conveyor belt 1 fixed on the frame for conveying tea leaves at high speed. The speed of the electric conveyor belt 1 is 1m / s-2m / s, so that the tea leaves have a high initial velocity when leaving the electric conveyor belt 1, and can perform parabolic motion. Multiple groups of mounting rods 11 are installed on both sides of the top of the electric conveyor belt 1. The tops of the multiple groups of mounting rods 11 are fixedly connected with a top rod 12. Transparent acrylic plates or glass are installed between the mounting rods 11 and the top rods 12 for protection and dust prevention, and for easy observation. Two groups of baffles 2 for guiding the tea leaves are symmetrically installed above the electric conveyor belt 1. The baffles 2 are fixedly connected to one side of the mounting rods 11, so that the tea leaves are kept at the center of the top of the electric conveyor belt 1, preventing some tea leaves from drifting to the outside of the conveyor belt and falling due to wind resistance during high-speed movement.

[0037] For further information, see Figure 2 and Figure 3The color sorter includes a tea collecting device 3 fixed on one side of the tea output end of the electric conveyor belt 1. The tea leaves at the tea output end of the electric conveyor belt 1 enter the tea collecting device 3 in a parabolic shape. The partition 31 located inside the tea collecting device 3 divides the tea collecting device 3 into a finished product channel and a defective channel. A finished product hopper 32 installed at the bottom of the tea collecting device 3 is provided below the finished product channel. At the same time, after the tea leaves fly out in a parabola, they directly enter the finished product channel in the tea collecting device 3 without being affected by external forces, and are discharged from the finished product hopper 32, so that tea leaves that can be directly filled and shipped can be collected below the finished product hopper 32. A waste hopper 33 installed at the bottom of the tea collecting device 3 is provided below the defective channel, so that tea leaves containing a large amount of impurities can be collected below the waste hopper 33, so that they can be sorted and recycled.

[0038] Specifically, Figure 3 and Figure 4 As shown, the color sorter further includes a cleaning mechanism 5 disposed above the tea collection device 3. The cleaning mechanism 5 includes a plurality of air pipes 52 evenly distributed along the width direction of the tea output end, and the air outlet of the air pipe 52 is disposed toward the side of the tea output end. After the impurities are detected, the air pipe 52 directly blows air to blow the tea leaves containing the impurities into the waste hopper 33 instead of directly into the finished product hopper 32. The cleaning mechanism 5 further includes a pneumatic device 51, a fixing block 53, and an air passage 54. The pneumatic device 51 is installed above the tea collection device 3. The pneumatic device 51 is connected to an air pump. After receiving the position information of the impurities sensed by the infrared sensor 4 after the processing module 7, the pneumatic device 51 triggers the air pipe 52 corresponding to the impurity position to exhaust air, and blows the impurities together with the tea leaves at the position thereof into the defective product channel below. The pneumatic device 51 is a prior art, and controls the corresponding air pipe 52 to blow air after receiving the signal, and will not be described in detail here. The fixed block 53 is arranged above the defective product channel, and multiple groups of air passages 54 are provided in the fixed block 53, the air passages 54 open downward, and multiple groups of air pipes 52 are correspondingly connected to the multiple groups of air passages 54, so that the position of the exhaust port of the air pipe 52 is fixed. At the same time, the air pipe 52 can also directly enter the fixed block 53, and the position of the air pipe 52 is fixed by the fixed block 53, so that the position of the air outlet of the air pipe 52 is fixed, thereby ensuring the accuracy of the air blowing and impurity removal. The impurity removal mechanism 5 also includes a fixed plate 55 and a connecting frame 56, and two groups of fixed plates 55 are symmetrically arranged on the top of the tea collection device 3, and the connecting frame 56 is fixedly connected between the two groups of fixed plates 55, and the positions of the fixed plate 55 and the connecting frame 56 are fixed. The fixed block 53 is installed on the connecting frame 56, and the position of the fixed block 53 is fixed.

[0039] Furthermore, the color sorter is provided with infrared sensors 4 above and below the air outlet of the air pipe 52, respectively. The infrared sensors 4 are facing the position where the tea leaves make parabolic motion, and the color of the tea leaves is identified. The position where the color difference occurs is regarded as impurities. The tea leaves detected by the infrared sensor 4 as containing impurities are quickly blown to the defective channel by the air pipe 52, and the other tea leaves enter the finished product channel. Both ends of the lower group of infrared sensors 4 are fixedly connected with mounting plates 8, which are fixed on the frame, and the position of the mounting plates 8 is fixed, so that the position of the infrared sensors 4 is fixed. A fill light 9 is installed between the two groups of mounting plates 8, and the position of the lower group of fill lights 9 is fixed. A top plate 71 is also connected between the top of the pneumatic device 51 and the processing module 7, and a fill light 9 is also installed on the top plate 71, and the position of the upper group of fill lights 9 is also fixed. Both groups of fill lights 9 face the position where the tea leaves move between the baffle 2 and the tea collection device 3, so as to illuminate the position where the tea leaves make parabolic motion, so that the infrared sensor 4 can accurately sense the tea leaves.

[0040] Finally, the two sides of the pneumatic device 51 are respectively fixedly connected with vertically arranged support plates 6, and the tea collection device 3 is fixedly connected between the two groups of support plates 6, so that the position of the tea collection device 3 is fixed. Two groups of connecting plates 61 are also symmetrically arranged on both sides of the pneumatic device 51, and the side of the pneumatic device 51 close to the baffle 2 is fixedly connected with the processing module 7 through the connecting plate 61, and the position of the processing module 7 is fixed. The infrared sensor 4 located above is installed on one side of the processing module 7, and the processing module 7 is used to process the impurity position information sensed by the infrared sensor 4 and send it to the pneumatic device 51, and the pneumatic device 51 controls the corresponding air pipe 52 to blow air to remove the impurities.

[0041] In this embodiment, the tea leaves are first evenly discharged onto the electric conveyor belt 1, which drives the tea leaves to move at high speed. At the end of the electric conveyor belt 1, the tea leaves fly out in a parabolic motion trajectory. At this time, when the tea leaves are moving, the upper and lower groups of fill lights 9 illuminate the tea leaves, making the color of the tea leaves bright. At the same time, when the tea leaves pass between the upper and lower groups of infrared sensors 4, the color of the tea leaves is quickly identified, and when impurities are detected, the signal is transmitted to the processing module 7 for processing. When the tea leaves are in parabolic motion, the tea leaves pass under the air pipe 52, and at the same time directly move to the finished product channel in the tea collection device 3, and are discharged through the finished product bucket 32. A collection bucket is set below the finished product bucket 32 ​​to collect the finished tea leaves. After the impurities are detected, the signal is processed by the processing module 7 and then sent to the pneumatic device 51. The pneumatic device 51 controls the air pipe 52 corresponding to the position of the impurities to exhaust. When the impurities pass under the air pipe 52, the air pipe 52 just blows the impurities and the tea leaves in the area where they exist to the defective channel below, and discharges them through the waste hopper 33, completing the removal of impurities. Therefore, the tea leaves discharged through the finished product hopper 32 are all high-quality tea leaves without impurities, which is convenient for improving product quality after filling and leaving the factory.

[0042] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
