滤网纸生产的核心问题就是在滤网纸生产过程中滤网纸张力需要保持恒定。不 合适的张力会影响滤网纸过滤效果和生产质量。假设滤网纸张力过大，滤网纸就会 紧绷变形更有甚者会断裂；但是滤网纸张力偏小，就会使滤网纸不能伸直，出现堆 积使机器出现故障。综上所述滤网纸生产过程中一定要保持滤网纸张力的恒定。

要保持张力恒定就需要通过电机动作来控制收放卷速度变化，收放卷机是空压 机滤网纸收放卷装置上的重要设备。收放卷机转速控制系统性能的好坏直接关系到 滤网纸卷能否符合生产要求,而且影响到滤网纸在后面的工作效果和工作质量。本 文通过控制收放卷机调节滤网纸张力,从而减小滤网纸张力变化，使生产的滤网纸 满足工业要求。

本文讲述了张力控制系统的发展史，还着重介绍了滤网纸控制技术的原理，以 及滤网纸张力控制系统对滤网纸的生产的必要性。然后分析了几种方式来实现滤网 纸的张力控制，结合空压机滤网纸的特殊牲，对滤网纸张力控制进行了模型分析， 并选择合适的控制方式，然后再选择适宜的张力检测元件及张力执行机构。把张力 检测单元检测到的张力值传送到 PLC 中，再通过 PLC 控制收放卷电机动作，从而保 持滤网纸张力恒定，保证滤网纸的质量和性能。

Abstract Tension control is filament winding, printing, paper, manufacturing one of the most widely used technology, with the development of modern winding equipment to high-speed, high-precision direction, tension control technology is particularly important。 Winding tension control technology is a roll of film production in key technologies, winding tension control accuracy, stability will directly affect the quality of the film composite apparatus adaptable and flexible film products。 The main task of this paper is the study of air compressor equipment filter paper tension control technology, the establishment of the winding tension control device mathematical model, select the tension control is suitable for special applications under the background, design a set to meet the industrial production index air compressor filter paper winding tension control system。

Filter paper core problem is unwinding and rewinding force control process needs to maintain a constant tension。 Improper tension will affect the filter paper transfer effects and production quality。 If the force is too large filter paper, filter paper easily deformed or broken; if the force is too small filter paper, filter paper can cause slippage deviation, but also wrinkles。 Therefore, the filter paper force control system must maintain a stable tension。

To maintain a constant tension on the need to move through the motor to control the operation of unwinding and rewinding motor speed change unwinding and rewinding machine is extremely important film production line equipment。 Retractable reeler correction control system performance is directly related to whether the pole piece reel alignment, thereby affecting the pole pieces, packing and shipping and subsequent treatment process。 By controlling the discharge retractable winder motor to adjust the force of the filter paper, thereby reducing the tension fluctuation on the filter paper results of the work。
