Reciprocating yarn-guiding system is a device for evenly and efficiently winding processed yarns into corresponding packages according to process requirements. Based on the traditional reciprocating yarn-guiding system and the linear magnetic driving mode, the linear magnetic reciprocating yarn-guiding system is proposed in this article. First, the technological requirements of conical package are analyzed, and the polynomial motion law based on reciprocating yarn-guiding mechanism is discussed emphatically. Second, the motion characteristics and operation mechanism of driving parts of reciprocating yarn-guiding mechanism are studied. The maximum acceleration models are established on two kinds of magnetic field analysis theories. Then, the appropriate models have been chosen by comparing the simulation results. And then, the movement functions of reciprocating yarn-guiding mechanism are ensured through the maximum acceleration model and the motion laws. Finally, the yarn distributions winding different types of yarns are simulated. The simulation results showed that the linear magnetic reciprocating yarn-guiding system based on polynomial motion law not only satisfied the fundamental requirements of package but also cut down one-stroke time and improved the efficiency of winding.
