DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, a high-strength moisture-proof corrugated cardboard surface defect online detection device, the controller 6 is respectively provided with wires between the second conveyor belt 9, the cylinder 11 and the motor 8, and the controller 6 is electrically connected to the second conveyor belt 9, the cylinder 11 and the motor 8 through the wires.

[0023] When the corrugated cardboard passes through the first fixed frame 4, the controller 6 controls the second conveyor belt 9 to stop running, and adjusts the height of the detector 15 according to the size of the corrugated cardboard on the second conveyor belt 9 so that the corrugated cardboard can be fully detected by the detector 15. The controller 6 controls the cylinder 11 to drive the detector 15 to move up and down to change the height of the detector 15. After the detection is completed, the controller 6 controls the second conveyor belt 9 to continue running until it reaches the sorting structure position.
