[0022] The screening side structure 5 includes a first connecting seat 51, an extension bracket 52, a screening sensor 53, a screening air cannon 54 and a limiting plate 55, and the first connecting seat 51 is fixedly installed on one side of the defective product output conveyor belt 3, and the extension bracket 52 is fixedly installed above the first connecting seat 51 and extends to the top of the tea input conveyor belt 4; the screening sensor 53 is fixedly installed inside the extension bracket 52 and is located directly above the tea input conveyor belt 4, and the screening air cannon 54 is fixedly installed inside the extension bracket 52; the limiting plate 55 is fixedly installed on the inner side of the first connecting seat 51 and extends downward, close to the surface of the defective product output conveyor belt 3.

[0023] The protective side structure 6 includes a second connecting seat 61, an extension plate 62, a guide plate 63 and a cut-off plate 64, and the second connecting seat 61 is fixedly installed on the other side of the defective product output conveyor belt 3, and the extension plate 62 is fixedly installed above the second connecting seat 61, and the guide plate 63 is fixedly installed above the extension plate 62; the cut-off plate 64 is fixedly installed above the guide plate 63.

[0024] The first connecting seat 51 inside the screening side structure 5 adopts a long steel metal seat, and the extension bracket 52 adopts several groups as needed, and the screening sensor 53 adopts a group of color sensors; the screening air cannon 54 adopts a stainless steel metal pipe, and the air outlet of the screening air cannon 54 faces the surface of the tea input conveyor belt 4 from the side, and the rear end of the screening air cannon 54 is connected to the compressed air pump; the limiting plate 55 adopts a steel metal plate perpendicular to the surface of the defective output conveyor belt 3, and the bottom end of the limiting plate 55 is close to the surface of the defective output conveyor belt 3, but not touching it.

[0025] The protective side structure 6 is made of stainless steel as a whole, and the guide plate 63 is a plate inclined inwardly, the bottom end of which is located at one-fifth of the surface of the defective product output conveyor belt 3; the cut-off plate 64 is a plate perpendicular to the surface of the defective product output conveyor belt 3, and the height of the cut-off plate 64 is higher than the surface of the tea input conveyor belt 4.

[0026] The tea screening device for tea processing is designed to automatically and efficiently separate inferior tea from high-quality tea to ensure the quality of the output tea. The device achieves accurate screening and processing of tea through the coordinated work of multiple structural components. Its working principle is as follows:

[0027] 1. Tea input:

[0028] The tea leaves enter the tea leaves input conveyor belt 4 through the tea leaves input hopper 7, and the tea leaves input hopper 7 is responsible for evenly distributing the tea leaves to be screened onto the conveyor belt for subsequent screening operations.

[0029] 2. Tea delivery:

[0030] The tea input conveyor belt 4 transports the tea leaves forward, and through the movement of the conveyor belt, the tea leaves gradually enter the screening area. This conveyor belt is installed on the surface of the supporting bottom plate 1 to ensure that the tea leaves move on a stable plane.

[0031] 3. Tea testing:

[0032] When the tea leaves move to the screening area, the screening sensor 53 installed inside the extension bracket 52 starts to work. The screening sensor 53 usually adopts a color sensor to detect the color of the tea leaves to identify inferior tea leaves.

[0033] 4. Elimination of inferior tea leaves:

[0034] Once the screening sensor 53 detects defective tea leaves, the screening air cannon 54 will be activated immediately. The screening air cannon 54 is connected to a compressed air pump and uses a jet of air to blow the defective tea leaves and a small amount of surrounding high-quality tea leaves off the conveyor belt. The direction and strength of the jet of air are precisely adjusted to ensure that the defective tea leaves can be effectively removed.

[0035] 5. Guidance for inferior tea:

[0036] The blown-off inferior tea leaves will first be intercepted by the cut-off plate 64 of the protective side structure 6. The cut-off plate is installed vertically, and its height exceeds the surface of the tea input conveyor belt 4, ensuring that the inferior tea leaves will not fly outside the device.

[0037] 6. Transport of inferior tea leaves:

[0038] The intercepted defective tea leaves will slide down along the inclined surface of the guide plate 63. The guide plate is inclined inwardly, and its bottom end is close to one-fifth of the surface of the defective product output conveyor belt 3, so that the defective tea leaves can fall smoothly onto the defective product output conveyor belt, and the moving direction of the defective product output conveyor belt 3 is opposite to that of the tea leaf input conveyor belt 4.

[0039] The defective tea leaves are transported to the defective tea outlet 2 for centralized processing or screening again. The defective tea leaves can be screened again on the conveyor belt 4 to improve the overall screening accuracy.

[0040] 7. High-quality tea output:

[0041] After screening, the tea leaves remaining on the tea conveyor belt 4 are high-quality tea leaves. Since the inferior tea leaves are effectively removed, the quality of the tea leaves that continue to move on the conveyor belt is guaranteed and can directly enter the next processing procedure.

[0042] in conclusion

[0043] The tea screening device for tea processing achieves efficient screening of tea through the coordinated work of components such as tea input conveyor belt, screening sensor, screening air cannon, protective side structure and defective output conveyor belt. Its working principle is simple and accurate, which can effectively remove defective tea and ensure the high quality of output tea, while ensuring the orderly processing and re-screening of defective tea, thus improving the overall screening efficiency and accuracy.

[0044] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
