The double-layer high-frequency vibrating screen machine is widely used in the tobacco industry, and its controllability of vibration has a great influence on the screening quality of cut tobacco. In this paper, we obtain the factors affecting the motion characteristics of the vibrating screen by theoretical derivation and experimental measurement of the motion parameters of the double-layer high-frequency vibrating screen machine, and determine the relationship between various factors and the amplitude of the vibrating screen. We also studied the properties of material motion. Through the overall research, we found that in the controllable process of realizing the high-frequency double-layer vibrating machine, we need to pay attention to the quality of the rotor of the motor, the angular velocity, and the radius of gyration, and also need to consider the number of spring piece and the rigidity of the spring piece. Also, the quality of the material will affect the movement of the screen.
