Corrugated paper is a plate-like object formed by bonding corrugated paper formed by processing a corrugated roll with a liner paper. In the production and processing process of the corrugated board, when the corrugated board enters the subsequent stacking from the paper outlet of the counting machine, the corrugated box printing has high requirements on the surface paper of the corrugated board, and the corrugated board is not allowed to have flaws and impressions. Therefore, in order to prevent the corrugated board surface paper from being scratched when the corrugated board surface paper enters the stacking machine, the corrugated board coming out of the counting machine needs to be turned over manually. At present, the board is turned over to current corrugated container board upset mainly divide into the manual work and turns over the board with the upset machine, and the manual work turns over the inefficiency of board, working strength is big, and current corrugated container board panel turnover machine can only overturn a corrugated container board when overturning the corrugated container board of stack, and the upset is inefficient, has seriously restricted the productivity of enterprise.

Although the corrugated board overturning and stacking device disclosed by the invention can overturn two corrugated boards at the same time, the overturning efficiency is still lower. The invention also discloses a corrugated board turnover machine and a full-automatic corrugated board turnover dislocation stacking machine as disclosed in the invention patent with the application number of 201611238316.X, which comprise a rack and a turnover assembly, wherein the turnover assembly comprises a turnover body and two transportation pieces, the turnover body is rotatably connected to the rack around a first rotating shaft, the transportation pieces are slidably connected to the turnover body along the radial direction of the first rotating shaft, the two transportation pieces can be close to or far away from each other, and the two transportation pieces are oppositely arranged and form a transportation channel suitable for transporting corrugated boards. Although the corrugated board turnover machine disclosed by the invention can turn over a plurality of stacked corrugated boards at one time, the middle corrugated boards are easy to throw out due to insufficient friction force between the corrugated boards or over-high turnover speed in the clamping and turning process. Therefore, aiming at the defects of the existing corrugated board turnover machine, the invention provides the corrugated board clamping turnover machine which is high in turnover efficiency and can effectively prevent the corrugated board from being thrown out.
