Abstract
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.
Highlights
The package plays an important role in yarn storage, dyeing, and machining; it has always been the focus attention on the textile industry to prepare high-quality winding and improve the digitalization and automation of the reciprocating yarn-guiding system.[1,2,3,4]
In the reciprocating yarn-guiding system, the differential micro gear set drives the forming cam to rotate, which makes the slider in the chute move reciprocally
A polynomial yarn-guiding motion law based on this system is proposed
Summary
The package plays an important role in yarn storage, dyeing, and machining; it has always been the focus attention on the textile industry to prepare high-quality winding and improve the digitalization and automation of the reciprocating yarn-guiding system.[1,2,3,4] At present, there are some reciprocating yarn-guiding systems such as forming cam and link pole reciprocating yarn-guiding system, rotary motor and ball screw reciprocating yarn-guiding system, and crank-link and sliding block reciprocating yarn-guiding system.
