[0031] The working principle of the screening table for white tea processing in the utility model:

[0032] When the screening table for white tea processing is working, a large amount of tea leaves are poured into the unloading hopper. When unloading is required, the unloading structure is opened, and the push plate is pulled back by pushing the cylinder, so that the discharge port below the unloading hopper can unload the tea through the push plate.

[0033] When the tea leaves fall into the mixing structure below the lower hopper, a certain amount of tea leaves are loaded into the mixing structure as required. After the discharging work is completed, the pushing cylinder pushes out the pushing plate to close the lower end of the lower hopper. When the mixing structure is loaded with an appropriate amount of tea leaves, the pushing cylinder below the lower hopper pushes out the pushing plate to close the discharging port below the lower hopper. Then, the driving motor drives the driving screw to drive the mixing structure, and the mixing structure moves toward the screening area at a uniform speed. When the lower part of the mixing structure is above the screening area, the mixing structure moves at a uniform speed as a whole. The flip motor in the mixing structure opens the mixing baffle to a suitable angle according to the tea discharging demand. Then, the tea leaves in the mixing hopper are discharged at a uniform speed through the gap opened by the mixing baffle. The tea leaves are spread over the screening area in a relatively even state. The dust collection box provided below the screening area removes the debris and fine debris mixed into the tea leaves.

[0034] When the material mixing structure has completely discharged the tea leaves, the driving motor will quickly move the material mixing structure to the bottom of the lower hopper, and the flipping motor will flip the material mixing baffle upwards to seal the bottom of the material mixing hopper, so that the lower feeding device returns to its original state, preparing for the subsequent tea screening work;

[0035] The spreading speed and thickness of the tea leaves can be adjusted according to the moving speed of the mixing structure and the opening angle of the mixing baffle, which can greatly meet the screening work of tea leaves of different specifications. The operator does not need to spread the tea leaves manually, and the impurity removal effect is further improved during the feeding process, reducing the workload of the operator.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
