Experiment and optimal design of a collection device for a residual plastic film baler

Abstract

It is imperative to carry out research on residual plastic film collection technology to solve the serious problem of farmland pollution. The residual plastic film baler was designed as a package for film strip collection, cleaning and baling. The collection device is a core component of the baler. Response surface analysis was used in this study to optimize the structure and working parameters for improving the collection efficiency of residual film and the impurity of film package. The results show that the factors affecting the collection rate of residual film and the impurity of the film package are the speed ratio (k) between the trash removal roller and eccentric collection mechanism, the number (z) and the mounting angle (θ) of spring teeth in the same revolution plane. For the collection rate, the importance of the three factors are in the order, k>z>θ. Meanwhile, for the impurity, the importance of three factors are in the order, z>k>θ. When the speed ratio, the mounting angle and the number of spring teeth was set at 1.6°, 45°, and 8°, respectively, the collection rate of residual film was 88.9% and the impurity of residual film package was 14.2% for the baler.
