Corrugated board turnover device and method thereof

The invention discloses a corrugated board turnover device and method, and relates to the technical field of corrugated board turnover, the corrugated board turnover device comprises a mounting seat, a fixed-angle turnover piece is mounted on the outer wall of a rotating shaft, locking pieces are arranged at the two ends of a positioning shaft, and a cleaning unit is arranged at the bottom of the positioning shaft. According to the device, a fixed-angle overturning piece is arranged, a rotating shaft rotates when a telescopic air cylinder contracts, in the process, a follow-up rotating gear rotates along an arc-shaped rack frame, a rectangular inserting block can move in the direction close to a connecting clamping block, and therefore two U-shaped clamping plates clamp and limit a corrugated board; when the follow-up rotating gear is separated from the arc-shaped rack frame, the corrugated board can be clamped and limited by the U-shaped clamping plate, so that the stability of the corrugated board in the ov
