Open the door! The advantages and characteristics of the tension control inverter winding are here.
。 In many industries of industrial production, precise tension control is required to maintain constant tension to improve product quality . 金等行业都被广泛应用。 Industries such as paper making, printing and dyeing, packaging, wire and cable, fiber optic cable, textile, leather, metal foil processing, fiber, rubber, metallurgy and other industries are widely used.
Before the frequency conversion technology was not mature, DC control was usually used to obtain good control performance. 的日趋成熟，出现了矢量控制变频器、 张力控制专用变频器等一些高性能的变频器 。 With the maturity of frequency conversion technology , some high-performance frequency converters such as vector control frequency converter and tension control special frequency converter have appeared . 动机。 Because of the structure, cost performance, use, maintenance and other aspects of AC motors are better than DC motors.
The purpose of tension control is to keep the tension on the wire or strip constant. For winding, the winding warp changes from small to large. In order to ensure constant tension, the output torque of the motor is required to change from small to large. At the same time, corresponding torque compensation should be performed in different operation processes. That is, the moment when the small roll starts, accelerate, decelerate, stop, and when the large roll starts, different torque compensation should be performed during different winding, so that the whole process of winding can be stabilized, and the tension during small rolls can be avoided ; The phenomenon of loose yarn when large rolls are started.
变频收卷的 优点有哪些？ Now let's find out what are the advantages of tension control frequency conversion winding ? For details, please see the following:
1. The tension setting is set on the man-machine, humanized operation, the unit is the unit of force: Newton.
2. Use advanced control algorithms: recursive calculation of the coil diameter; linear increase of tension when the hollow coil diameter is activated.
3. Application of tension taper calculation formula, dynamic adjustment of torque compensation and so on.
4. Real-time calculation of the winding diameter, the accuracy is very high, and the smooth performance of the output torque of the winding motor is guaranteed. 了卷径的递归运算，在操作失误的时候，能自己纠正卷径到正确的数值。 In addition, a recursive calculation of the coil diameter is added in the calculation of the coil diameter, and when the operation error occurs, the coil diameter can be corrected to the correct value by itself.
是在传统机械传动收卷的基础上改造成变频收卷，非常简便而且造价低，基本上不需对 原有机械进行改造。 5. The tension control is based on the traditional mechanical transmission winding, which is transformed into a frequency conversion winding. It is very simple and low in cost. Basically, there is no need to modify the original machine. The transformation period is small, and basically the installation and commissioning can be completed in two or three days.
6. It overcomes the disadvantages of mechanical winding on mechanical wear and prolongs the service life of the machine. Easy to maintain equipment.
系统。 In many paper mills, color printing factories, weaving and dyeing factories, etc., there are tension control systems used in the production process with winding processing. Then a tension control system with superior performance is very important to the enterprise. As a manufacturer of electromechanical products, Hailing Magnetic Powder has superior tension controller performance, which has been recognized and praised by customers. Welcome.
