Design and experiment of the device for removing paper bags from the broken handle of pear
Aiming at the problems of manual cutting of the handle of the crown pears after picking that requires the high labor intensity for bag removal,a handle-breaking and bag-removing integrated machine was designed,and its handle-breaking device was optimized.Matlab software was used to calculate the bag removal movement of the bag removal robot Trajectory.In order to optimize the structural parameters of the device,a three-factor Box-Behnken test was designed.The design-Expert software was used to analyze the variance of the test results,and a regression model of significant parameters was established to obtain the optimal structure of the crown pear broken handle and bag removal device Parameters.The cutting gap was 0.89 mm.the"V"-shaped positioning opening angle of the positioning plate was 36.5°,and the feed per tooth was 7.8 r/min.With this combination,the broken handle rate was 90.15%,and the average width of the paper bag tear was 50.63 mm.The research results can provide a theoretical basis for the design and improvement of the device for removing the broken handle of the crown pear.
