一种新颖的宝塔线长度测量控制仪

仪器以直接测长的方式，克服了传统的由齿轮相互搭配间接控制线长和由测转速换算到线长的方法所带来的测量和控制误差。整机设计合理，构造精密，闭环在线测量和控制线长精度优于国家标准GB6863－86，适用于制线工业和化纤工业的绕线长度的测量和控制。

New Instrument for Measuring the Length of the Thread on Cone

A new instrument for directly measuring the length of the thread on cone is developed here, which can overcome Some tolerances and disadvantages introduced by traditional measuring methods via the gear-coordination and via the measurement of the rotation velocity, The design of the whole instrument processes a series of features, such as rational parameters selected, precise structure, etc The precision of the on-line close-circle measurement and controlling of the length of the thread is better than the state standards of GB6863 - 86. The instrument can be well used for measuring and controlling the length of the thread in the thread industry as well as in the chemical fiber industry.
