钢帘线收线机的张力控制装置

钢帘线收线机的张力波动直接影响钢帘线的质量,选择张力的控制方式十分重要。说明收线机常用的几种控制方式,分析其控制原理及优缺点,给出结构图。机械摩擦式张力收线机主要是通过调节碟簧压力来实现恒张力收线,使用中摩擦盘容易磨损,维护成本高;永磁式张力收线机是通过永磁滞差速装置实现恒张力收线,运行时噪声低,无机械冲击;力矩电机驱动的收线机负载特性软,主要用于内放外收型捻股机;变频控制的收线能自动跟踪收线过程中的张力变化,控制精度高,张力适应范围广。

Tension control device of steel cord take-up

The tension fluctuation of steel cord take-up affects steel cord quality directly.It is very important to choose control way of tension.Some common control ways of take-up are illustrated,and its control principle,advantages and disadvantages are analyzed,structure diagram is given out.Mechanical frictional type tension take-up realizes constant tension take-up by adjusting disc spring pressure,friction disc wears easily and maintenance cost is high in using;permanent magnet type tension take-up realizes co...
