When the carrying arm 23 moves to the left, the topmost plate can be pushed to the left by turning the screw 24; the height of the screw 24 below the carrying arm 23 can also be adjusted by rotating the screw 24 to push plates of different thicknesses and the number of plates pushed; After the topmost plate is pushed to the left and moved out of the limit frame 171, the plate will be inserted between the two conveying rollers 35 and enter the guide unit 39 supported by the first arm 391; by driving the first motor 36 in the feeding structure 3, through the transmission of the pulley 37 and the transmission belt 38, the conveying rollers 35 between the bottom roller frames 30 are driven to rotate and apply force, and the plate is driven to pass through the two conveying rollers 35 for support and force, so that it is received by the guide plate 393 between the second arm 392 in the guide unit 39, and then continuously fed to the left through the guide roller 395 between the roller arms 394; According to the thickness of different plates, the limit nut 34 can be rotated to adjust the length of the driving screw 31 passing through the roller frame 30, that is, to adjust the height of the lifting seat 32, and adjust the distance between the two conveying rollers 35 to allow plates of different thicknesses to pass through; and after the plates pass between the two conveying rollers 35, the lifting seat 32 can be driven by the conveying rollers 35 to rise and compacted with the help of the second spring 33 to apply downward force.
