The rotating disc type winding device comprises a left rotating disc and a right rotating disc which can rotate, two winding shafts are arranged between the left rotating disc and the right rotating disc and are parallel and symmetrical about a central axis of the rotating discs, one winding shaft is located at a winding position and is called a main winding shaft, and the other winding shaft is located at a discharging position and is called a standby winding shaft. The two winding shafts are driven by the turntable to turn over and are used as a main winding shaft and a standby winding shaft in turn. The distinction between the "take-up position" and the "take-off position" is determined by the arrangement of the entire production line, and the "take-up position" and the "take-off position" are spatially fixed and do not change with the rotation of the turntable. Specifically, when the film is normally wound, the main winding shaft is responsible for winding the film; when the film coiled by the main coiling shaft reaches a set length, the coiling is carried out, when the coiling is changed, the turntable rotates 180 degrees around the rotating shaft of the turntable, the original main coiling shaft rotates to the unloading position to become a new standby coiling shaft, the original standby coiling shaft rotates to the coiling position to become a new main coiling shaft, then the film is cut off by the cutter, the film newly conveyed at the upstream of the production line is coiled by the new main coiling shaft, and the new standby coiling shaft carries out the operations of unloading a finished film coil, installing a new paper core cylinder and the like to wait for the next circulation to be in a standby state.
