What Is The Working Principle Of The Tension Controller?

The tension controller is a device in life that can permanently control the tension of the tape as it is transported on the device. The use of such equipment keeps the speed of the equipment well and keeps production unaffected in an emergency. So what is the working principle of this kind of equipment? Let's take a look at the introduction of experts!

The tension controller works mainly through the coil. The coil stationary magnetic powder clutch and the magnetic powder brake are automatic devices that control the input current to change the output transition. When the coil is not energized, the input shaft rotates, and the magnetic powder is pressed against the inner wall of the clamp ring by the centrifugal force, and the output shaft is not in contact with the input shaft. At this time, it is in an idling state. When the coil is energized, the magnetic powder generates a magnetic flux under the action of the magnetic force line, so that the output shaft and the input shaft become a rigid body and rotate, and a slip occurs when the overload occurs, and the working state is at this time. Thereby achieving the purpose of transmitting torque.

Tension controller This device consists of a magnetic powder brake and a clutch. According to the loop, it can be divided into open loop, closed loop or free loop tension control system; according to the monitoring method of different coils, it can be divided into ultrasonic type, floating type, tracking arm type and so on. The stability of tension control is directly related to the quality of the slitting product. If the tension is insufficient, the raw material will drift during operation, and the finished paper will wrinkle after slitting and rewinding; if the tension is too large, the raw material will be easily broken, so that the finished paper breaks after slitting and rewinding.

Through the introduction of the above-mentioned aerospace experts on the working principle of the tension controller, everyone has a certain understanding of this equipment in life. It is also very helpful to us when we use it.

Tension controller debugging steps

In short, the same normal tension controller only needs to be placed and debugged and fine-tuned for two basic operations. Other specific parameters depend on the specific results necessary.

The steps of resettlement and debugging are very simple. It can be done step by step by listening to the clarification book. It is usually the same as clearing, calibration, etc. depending on the difference model. Fine tuning is based on the tension control system with PID setting results

To deal with a controller, the PID setting is the same as usual: the same as usual, the differential D value is set to zero, the integral I is set to a small number between 5-10, and the change P value is from small to large until the system Can mediate stability, when P mediation is good, add an external nuisance, see the time required for the system to recover to balance, if it is too slow, increase the value of I until the result is satisfactory, the same system changes two cycles to reach equilibrium For the best.

As for the most fundamental role of the tension controller, although it is to control the tension, a constant tension system is exemplified. The actual value of the tension is compared with the set value to control the magnitude of the output value.

For example, the tension setting is 5N. When the actual value is greater than 5N, the output value becomes smaller/larger (depending on the phase setting) and the infinitely approaches 100%/0 (depending on the phase setting) to control the braking torque. Probably the frequency of the inverter. When the tension is too large or too small, the size of the set value should be properly adjusted.
