Straightening device and control method thereof

The invention discloses a straightening device and a control method thereof, and relates to the technical field of straightening. The straightening device comprises a feeding mechanism, a feeding roller way, a first transition roller way, a straightening mechanism, a position detector and a controller. The feeding roller way is connected with the straightening mechanism through the first transition roller way, the feeding direction of the feeding roller way is the same as that of the first transition roller way, the position of the feeding mechanism corresponds to that of the feeding roller way, the position detector is electrically connected with the controller, and the controller is electrically connected with the feeding mechanism, the feeding roller way, the first transition roller way and the straightening mechanism at the same time. The first transition roller way is oppositely provided with a first inlet end and a first outlet end, and the controller is used for controlling the feeding ...
