During the carpet tufting process, the mechanics and kinematic performance of the tufting needles restrict the increase of the spindle speed and affect the vibration characteristics of the entire mechanical system, while the kinematic performance of the tufting needles directly depends on the design of the transmission mechanism. Working principle, the tufting needle transmission mechanism composed of crank-rocker mechanism and crank-slider mechanism is designed, and the movement of the transmission link mechanism is mathematically analyzed; the transmission under different crank parameters is analyzed by ADAMS simulation software The movement analysis and comparison of the mechanism are carried out, focusing on the movement of the tufting needle when it penetrates into the base fabric.
