Abstract

Abstract: In response to the problems of incomplete film removal and low reliability in the elastic tooth chain rake residual film recycling machine, a fixed scraper type peel off device was designed, and its key components were designed and analyzed. To verify the operational performance of the peel off device, an L₉（3⁴） orthogonal experiment was conducted with the driving speed of the machine （A）, the length of the spring teeth （B）, and the angle between the spring teeth and the delamination plate （C） as experimental factors, and the delamination rate as the experimental indicator. The results showed that the delamination rate of the elastic tooth chain rake residual film recycling machine was 92.5% to 95.7%;the range analysis showed that the influence magnitude of each factor was A>C>B. The optimal experimental condition combination for the delamination rate was A₂B₁C₂, which meant that the machine’s driving speed was 8 km/h, the length of the spring teeth was 160 cm, and the angle between the spring teeth and the delamination plate was 50°. Validation tests were conducted on the optimal combination （A₂B₁C₂） for 5 times, with an average delamination rate of 95.16%, meeting the operational requirements of the the elastic tooth chain rake residual film recycling machine.
