[0002] As people's living standards continue to improve, tea has become more popular with tea beverages because of its natural, healthy, and convenient drinking characteristics. At the same time, the quality requirements for tea are getting higher and higher. In the process of making tea, since the collected tea leaves are of different sizes and shapes, the grades of the finished products are also different, so before making them, the tea leaves must be screened. The existing screening of tea leaves by size usually uses a single mesh manual shaking filter screen, which has low screening efficiency, increases the workload of the staff, and has a low use effect. In addition, due to the single mesh, it is impossible to perform multi-grade screening during screening, resulting in insufficient practicality.

The utility model can effectively improve the screening efficiency of tea through the device, and can achieve the screening effect of tea raw materials through the combination of springs and linear motors.

[0009] A material discharging hopper is fixedly connected to the upper part of the screening machine box, a quantitative feeding cylinder is slidably provided at the lower part of the material discharging hopper, and a material blocking plate is fixedly connected to the quantitative feeding cylinder.

[0010] Furthermore, the screening frame is vertically slidably arranged on the movable slot, and the apertures of the plurality of screening screens gradually decrease from top to bottom.

[0011] Furthermore, an infrared sensor matched with the material blocking plate is fixedly connected to the screening machine chassis, and a controller is fixedly connected to the screening machine chassis.

[0012] Furthermore, the infrared sensor is electrically connected to the controller, and the controller is electrically connected to the electric push rod.
