[0023] During use, the staff first places the paper on the top surface of the workbench 1, then starts the first hydraulic push rod 4 on the front side, so that the fixed plate 5 on the front side moves downward, presses and fixes the front end of the paper, then starts the second hydraulic push rod 9 to move the U-shaped frame 10 and the internal squeezing roller 11 downward, so that the squeezing roller 11 presses against the paper, then starts the guide rail 6, so that the slider of the guide rail 6 moves forward and backward, thereby driving the L-shaped frame 7 and the squeezing roller 11 to move forward and backward to flatten the wrinkles on the paper, then starts the first hydraulic push rod 4 on the front side again, so that the fixed plate 5 on the front side moves up and resets, then starts the first hydraulic push rod 4 on the rear side, so that the fixed plate 5 on the rear side moves downward to press and fix the rear end of the paper, and then flattens the wrinkles on the paper again through the squeezing roller 11. It is conducive to flattening the wrinkles of the paper, and at the same time, it is conducive to fixing the front and rear ends of the paper respectively, so as to improve the stability of the paper wrinkle flattening process, and to prevent the paper from moving, so as to improve the flattening effect and flatness of the paper.
