Design and Parameter Optimization of Slicing Machines Based on New Rotary-straight Line Reciprocating Mechanisms
Aiming at the problems of low slicing efficiency and quality of the existing pastry sli-cing machines,the design analysis and parameter optimization of a slicing machine was carried out based on the new rotary-linear reciprocating mechanisms.Firstly,the design of the slicing mecha-nisms and the calculation of the length-diameter ratio and speed of the elliptical guide rail was carried out.Secondly,the kinematics and the statics analyses were carried out,then,based on the simulation analysis of different aspect ratios and rotational speed dynamics,the cubic polynomial fitting equation of the mean and root mean square value of the cutter acceleration was constructed as the objective function.The NSGA-Ⅱ genetic algorithm was used to optimize the long and short diameter multi-ob-jective parameters,and the rotational speed was selected.Finally,a prototype was built to complete the comparative experiments of different speeds and the performance tests of corn cake slices.The re-sults show that the optimal long and short diameters and rotation speeds are as 190 mm,120 mm and 20 r/min respectively.After optimization,the cutter efficiency is increased by 75％,the maximum and average errors of the cutter feeding acceleration are reduced by 26％and 49％respectively,and the maximum and arerage errors of retract acceleration are reduced by 60％and 63％respectively.The corn cake section is neat and beautiful,which verifies the feasibility of the design.
