【摘要】 介绍一种在瓦楞纸板生产线上能自动调节原纸张力的张力测控装置。该装置由单片机控制电控气动比例阀的输出气压,由使用该气压进行制动的气刹来调节张力的大小,在整个生产过程中,使原纸始终处于恒张力的状态下,从而消除了断纸现象。更多还原

【Abstract】 This paper introduces a measure and control device of paper tension which can automatically adjust paper tension in the production line for currugated board. In this device, a singlechip microcomputer is used to control the output pressure of the electricitycontrolled pneumatic ratio valve. And an air brake driven by this pressure regulates the paper tension. In the whole production process, the paper is always kept in a constant tension state and so the broken paper phenomena is eliminated.更多还原
