张力控制是提高产品合格率、改善产品质量的关键技术,而开卷段控制系统的主要任务就是保持张力的恒定,它是开卷段控制系统的核心部分。本文在开卷机后增加了一个跳动辊装置,通过中间辊轮的高度即可判断出张力的变化,然后再通过调节开卷机的转速从而保证开卷段张力的恒定。
Tension control is to improve the product qualification rate, improve product quality, the key technology, and uncoiler control system is the main task of maintaining a constant tension, it is the core part of the uncoiler control system. This paper adds a beating roller device after the uncoiler, through the height of the middle roller can determine the change of tension, and then by adjusting the uncoiler speed so as to ensure uncoiler tension constant.
