绕线机绕线张力控制方法分析

分析胶管和电缆等纤维线绕线机的绕线过程和绕线张力,得出绕线张力变化发生在排线跃层提速的过程中,建立了恒转速模式下的绕线张力计算模型,得出绕线张力变化率正比于小线轴卷绕转速平方和线直径,并给出了恒转速控制方法的应用范围,其经济性好。与恒转速控制方法相比,当选取的小线轴卷绕转速和线直径较大时,恒线速度控制方法的绕线张力控制效果更优,但系统复杂性和成本显著提高。

Analysis of Winding Tension Control Method of Winding Machine

The winding process and winding tension of fiber winding machine for hose and cable were analyzed. It was concluded that the winding tension changed in the speed-up process of the winding. The winding tension calculation model under the constant rotating speed mode was established. It was concluded that the winding tension change rate was proportional to the square of small spool rotating speed and the wire diameter. The application scope of the constant rotating speed control method was then obtained,and the economic benefit of this method was good. Compared with constant rotating speed control method,when the selected small spool rotating speed and wire diameter was large,the winding tension control effect of constant linear speed control method was better,but the system complexity and cost increased significantly.
