| Abstract: |
| To further study the influence of different working parameters on the film winding effects of the floating pneumatic film winding device in the process of residual film recovery, this study established an internal airfield model of the floating pneumatic film winding device by using SolidWorks Flow Simulation software to simulate the dynamic change process of airflow in the process of film winding. Three\|factor and three\|level Box\|Behnken experimental design method was used. Fan installation angle, inlet air flow velocity, the roll of film roll speed and evaluation of floating type pneumatic film device operation effects related to three different location speed value (driven roller surface vertical airflow velocity v1, roll film roll surface horizontal airflow velocity v2 and guide diaphragm surface airflow velocity under v3) and the mathematical model for floating pneumatic membrane device of the optimal parameter combination were established. The field validation experiments were carried out. The simulation results showed that when the fan installation angle was 33°, the inlet air velocity was 3.50 m·s-1 and the film roller speed was 17 rad·s-1, the response value to evaluate the operation effect of the floating pneumatic film winding device reached the optimum. The results of field experiment showed that after optimizing the working parameters of the floating pneumatic film winding device, the recovery rate of residual film of the combined potato harvesting and pneumatic assisted residual film recovery machine was 91.6%, and the impurity content rate was 7.5%, which met the national and industrial requirements. |
