Optimization of presser foot and needle bar driving mechanism based on the complex method principle

The rod presser foot and needle bar driving mechanism of the embroidery machine cannot achieve accurate parking time position at high speed, which limits development speed make quality decline. Aiming solving this bottleneck problem, characteristics based on analyzing kinematics is developed. These influences each linkage parameters are analyzed. Six main selected to optimize by using complex method. Taking as constraints, linkages was optimized in order obtain maximum mechanism. results show that more reasonable effective, pause increased 15.5%, 100° ± 0.5° required technological requirements, satisfies requirements coordinate movement bar-presser drive high-speed machine. study also provides a method reference for follow-up research development.
