    由本生产线的工艺流程可以看出：开卷、展平、修边、碎边和校平应在一个线速度V1下同步运行。定尺送进和皮带之间设有横剪刀，因此，定尺送进、皮带和横剪刀是断续运行，同时，它的运行速度V2应大于V1。在校平机与定尺送进机之间的缓冲坑，其作用是：平衡V1和V2之间的速度关系，保证生产线的稳定运行。 

三、电气控制方案： 
        展平、修边、碎边和校平的运行速度容易实现同步，只要将电机的旋转速度按照自身的减速器、传动辊子等的机械参数折算成线速度，与生产线的线速度V1统一即可。 
        在开卷工作中，由于卷径是在不断变化的，开卷电机的旋转速度与生产线的线速度V1很难找到匹配关系。换句话说，如何解决开卷机与整条生产线的运行速度V1同步的问题，是电气设计的主要工作之一。 定尺送进、横剪刀和皮带是断续运行。板材由定尺送进机的牵引辊按照加工要求的长度送入剪扳，机进行横向剪切。因此，定尺送进机是生产线的位置控制精度要求最高的设备。 
目前，开卷机的控制有以下几种方案： 
①、 电磁滑差调速：手动调节开卷机的转速，使之与生产线的线速度一致。 
②、 张力控制：利用板材表面张力恒定的原理，使之自动跟随生产线的线速度。 
张力控制的实施又分为：力矩电机、直流电机、张力控制器等。 
方案①的优点：电气控制简单，造价低廉。缺点：控制方式陈旧，劳动量大，效率低，耗能高，无法实现生产线的自动运行。 
方案②的优点：操作简单，自动化程度高。缺点：控制复杂，造价高昂。 
我们经过调研，决定采用艾默生TD3300张力控制交流变频器，使开卷机在张力的控制下，自动跟随生产线的线速度。在自动化程度不降低的前提下，大大降低了开卷生产线的制造成本，提高了性能价格比。
