| Abstract: |
| A vertical double\|row chain residual film recovery machine was designed to address the problems of high contamination rate and poor utilization rate of residual film recovery in the current residual film recovery machine. The structure and working principle of the machine were introduced, and the key structure and parameters of the conveying device were analyzed. The kinematics and dynamics of the conveying and unloading process of the vertical double\|row chain operation were studied. The operating parameters of the main working parts were determined by theoretical calculation, and the key factors affecting the performance of film recovery were obtained. The results showed that the optimum parameters affecting the film recovery performance were 86.08 r·min-1 of conveyor chain speed, 128.97 r·min-1 of unloading chain speed and 91.92° of transfer angle of conveyor chain. The film recovery rate was 86.3% and the trash rate was 36.57% under the optimum combination of parameters. The actual recovery rate of residual film under the optimal combination of parameters was 86.7% and the trash rate was 35.9%, which met the industry requirements. |
