The invention relates to the technical field of corrugated board overturning machines, and particularly discloses a corrugated board clamping overturning machine.
The corrugated paper is a plate-like article formed by bonding a face paper and corrugated paper having a corrugated shape formed by corrugating a corrugated roll. In the production and processing process of the corrugated board, when the corrugated board enters the subsequent stacking from the paper outlet of the counter, the requirement of the corrugated board on the surface paper of the corrugated board is very high due to the printing of the corrugated board, and the corrugated board is not allowed to have flaws and indentations. Therefore, in order to protect corrugated paper board from being scratched when the corrugated paper board enters the stacking, the corrugated paper board from the counter needs to be manually turned over. At present, the existing corrugated board overturning is mainly divided into a manual overturning plate and an overturning machine overturning plate, the efficiency of the manual overturning plate is low, the working strength is high, and the existing corrugated board overturning machine can only overturn one corrugated board when overturning stacked corrugated boards, so that the overturning efficiency is low, and the productivity of enterprises is severely restricted.
For example, the invention patent with the application number of 2020103991374 discloses a corrugated board overturning and stacking device, which comprises a first support column and a second support column, wherein the second support column is arranged on one side of the first support column, a motor base is arranged on one side of the first support column, and a rotary turntable is used for rotating a screw rod. The corrugated board overturning and stacking device disclosed by the invention can overturn two boards at the same time, but the overturning efficiency is still lower. The invention patent with the application number of 20161238316. X discloses a corrugated board overturning machine and a full-automatic corrugated board overturning staggered stacking machine, and the full-automatic corrugated board overturning staggered stacking machine comprises a frame and an overturning assembly, wherein the overturning assembly comprises an overturning body and two conveying pieces, the overturning body is rotatably connected to the frame around a first rotating shaft, the conveying pieces are slidably connected to the overturning body along the radial direction of the first rotating shaft, the two conveying pieces can be mutually close to or far away from each other, and the two conveying pieces are oppositely arranged and form a conveying channel suitable for conveying the corrugated board. The corrugated board turning machine disclosed by the invention can turn a plurality of stacked corrugated boards at one time, but the middle corrugated boards are easy to be thrown out due to insufficient friction force or over-high turning speed between the boards in the clamping and turning process. Therefore, the invention provides the corrugated board clamping and overturning machine which has high overturning efficiency and can effectively prevent corrugated boards from being thrown out.
