[0002] Coiled materials are products made of sheet metal, cloth, etc. that are wound and reeled onto rollers. To continue processing or collecting the coiled materials, a control device is required to control the unloading and reeling of the coiled materials. Conventional equipment of this type directly uses a motor to connect the roller to a fixed drive shaft. If the motor stops, the roller will continue to rotate.

If the surrounding machines cannot stop quickly, the coil will be damaged and the transmission efficiency will be affected. It will also be impossible to apply tension to the coil.

[0004] Now, a new type of automatic unwinding control device is proposed to solve the above problems. Utility Model Content
