Recycling of waste plastics has a positive role in promoting carbon peak and carbon neutralization.Vibration separation technology is the key technology of high-precision separation of waste plastics.According to the characteristics of different types of waste plastic films,the vibration separation mechanism was analyzed,and the appropriate vibration separation mechanism was determined.The layered vibration separation technology was proposed,and the ADAMS simulation optimization model of waste plastic film on the vibration separator was established.The motion parameters and structural parameters of the vibration bed were optimized.So that the length of vibration sorting mechanism is reduced by 11%,and its width is reduced by 50%,and the manufacturing cost of the separation system is saved.The stability of the layered vibration sorting prototype was verified by ANSYS modal analysis.The lightweight design of the prototype components was carried out,and the structural prototype model was constructed,which laid foundation for the design and manufacture of the actual prototype.
