[0002] The coil unwinding mechanism is responsible for smoothly and continuously unwinding the coil from the material roll and sending it to the next working area at a certain speed. The unwinding mechanism is usually the starting link of production. The performance of the unwinding mechanism directly affects the continuity of production and the quality of the product.

[0003] In order to maintain a stable unwinding tension during the unwinding process, the existing coil unwinding mechanism usually adopts magnetic powder brakes and electromagnetic brakes. In large paper mills, steel rolling mills, coating plants and other fields, the coil volume is huge and a particularly large tension needs to be provided to the coil.
