Advantages and disadvantages of magnetic tensioner

In the tension control system, the magnetic tensor brake and clutch as the terminal execution mechanism, the quality of its performance has a direct impact on product quality and cost. Our company's production equipment is mainly equipped with Mitsubishi LE-40MTA tension controllers. Its execution agencies use traditional magnetic powder brakes. The control process is shown in Figure 1. Because the printing workshop has a certain humidity, the magnetic powder in the magnetic powder brake is vulnerable to moisture, or due to the high working temperature, it is easy to cause the magnetic powder brake control to control the failure and increase the waste rate. Moreover, the maintenance of magnetic powder brakes is difficult.

Features: The magnetic tensioner is damped by magnetic torque and has no mechanical friction. Therefore, it can produce stable tension for a long time, and the accuracy can be effectively guaranteed. It is suitable for the use of general products with accuracy requirements. The price is low! Economy!

Working principle: Use non -contact magnetic torque to provide torque.

Advantages: magnetic tensioner is damped by magnetic torque and has no mechanical friction, so it can produce stable tension for a long time, and the accuracy can be valid

ensure. The MTA class can also provide two tension to meet the needs of the feet when winding.

Disadvantages: Due to the limitation of the structure of the tension items, when setting the tension of the winding, you can only adjust from the tension to the big tension. If you want to adjust the big tension into a small tension, you must reduce it under the parking state and then reduce it to the winding state before the winding state. The tension is required.
