At this time, the pulled raw material strip will be redundant and dirty on the ground. Therefore, a reel brake device for cutting the ventilation duct raw material roll is needed, which can brake the raw material roll that has stopped cutting to avoid the raw material roll from dragging on the ground and getting dirty due to inertial rotation.
