In order to solve the problem of the complicated calculation in the manual design of the collective doffing lifting system of spinning frame and effectively improve the design progress and manufacturing efficiency,this paper introduces the motion law of the collective doffing lifting system of the spinning frame,and establishes the motion mathematical model of the system based on the structural mechanics and displacement analysis of the herringbone arm.Taking spinning frame series TH598 with collective doffing system as an example,the program design is carried out based on Matlab.The mechanical and displacement characteristic curves of the spinning frame are analyzed.It is pointed out that the mechanical and displacement characteristic curves of the spinning frame can be plotted with Matlab,and the precise coordinates of the spinning frame can be obtained.It provides a theoretical basis for the selection and mechanical debugging of the driving motor of the spinning frame,and effectively improves the design progress and manufacturing efficiency.
