Study on vibration sorting of waste plastic film by micro-element trajectory method

The sorting of waste plastic film can effectively protect the environment, improve energy effi-ciency, and effectively improve its recycling value. In this paper, a new method for solving the vibration sorting trajectory of waste plastic film, micro-element trajectory method, was proposed. The mathematical model of the thin film vibration was established, the force of the thin film was analyzed, and the motion trajectory of the thin film was obtained. The experimental platform was built to obtain the displacement difference of different thin film vibration sorting. The simulation experiment was carried out by ADAMS. Compared with the experimental results and simulation results, the correctness of the algorithm was verified. The comparison results show that compared with the experimental results, the average error rate of the sorting displacement difference of different thin films is 3.17 %; and compared with the simulation experiment, the average error rate of the motion trajectory calculated by using the single film is 5 %, the error is small. The algorithm has small amount of calculation and fast calculation speed. It provides an efficient and reliable calculation method for the follow-up research of waste plastic film vibration sorting technology.
