张力控制，通俗地讲，就是要控制卷取物体时保持物体相互拉长或者绷紧的力。张力应用于最广泛的造纸、纤维、塑料薄膜、电线、印刷品、磁带等轻工业中，带材或线材的收放卷张力对产品的质量起着至关重要的作用。在收卷和放卷的过程中，为保证生产的质量及效率，保持恒定的张力是很重要的。Tension control, in layman's terms, is to control the force that keeps objects elongated or taut when they are being taken. Tension is used in the widest range of light industry such as paper, fiber, plastic film, wire, printed matter, tape, etc. The tension of the strip or wire is critical to the quality of the product. In order to ensure the quality and efficiency of production, it is important to maintain a constant tension during the winding and unwinding process.
在冶金、造纸、纺织等行业中，在加工过程中或者是加工完成之后，最后的一道工序一般就是将加工物卷绕成筒状。在这一过程中，卷绕的好坏将是决定产品质量的关键，卷的太紧，容易使织物变形，拉断，卷的太松又容易使卷取不紧凑，不利于搬运和运输，因而为了达到使卷绕紧凑，保证产品的质量，都要求在卷绕过程中，在织物上建立一定的张力，并保持张力为一恒定值，能够实现这一功能的系统，就叫做张力控制系统。目前应用的张力控制系统，根据其测量控制的原理结构主要有三种：间接法张力控制系统；直接法张力控制系统；兼有间接法和直接法的复合张力控制系统。In the metallurgy, papermaking, textile and other industries, in the process of processing or after the completion of processing, the last process is generally to wind the processed product into a cylindrical shape. In this process, the quality of the winding will be the key to determine the quality of the product. The volume is too tight, the fabric is easily deformed, the fabric is broken, the coil is too loose and the coiling is not compact, which is not conducive to handling and transportation. Therefore, in order to achieve compact winding and ensure the quality of the product, it is required to establish a certain tension on the fabric during the winding process and maintain the tension at a constant value. The system capable of realizing this function is called the tension control system. . At present, the tension control system applied has three main principles according to its measurement control: indirect method tension control system; direct method tension control system; and composite tension control system with indirect method and direct method.
从控制方式上分类，张力控制一般可以分为手动、半自动、全自动三类；卷径控制方式可自动检测卷径从而对张力的执行机构进行调整、补偿，实现张力的恒定。卷径控制方式属于半自动控制方式，其突出特点就是省去了价格相对昂贵的张力传感器，安装简单，而且能很方便的获得锥度张力控制，特别适用于冶金、印刷、包装、造纸、印染等行业的分切及收卷机器设备。According to the classification of control methods, the tension control can be generally divided into three types: manual, semi-automatic and fully automatic; the winding diameter control method can automatically detect the winding diameter to adjust and compensate the tension actuator to achieve constant tension. The roll diameter control method is a semi-automatic control mode. Its outstanding feature is that it eliminates the relatively expensive tension sensor, which is easy to install and can easily obtain taper tension control. It is especially suitable for metallurgy, printing, packaging, paper making, printing and dyeing industries. Cutting and winding machines.
