When the first movable seat 33 and the stop plate 53 abut, the first movable seat 33 and the first friction plate 49 return to the initial position relative to the paper feeding table 1. As the second movable plate 36 continues to move, the second friction plate 50 slides relative to the first friction plate 49 until the second movable plate 36 and the second friction plate 50 move to the initial position. This can correct the deviation of paperboards of different specifications, thereby improving the scope of application. The design of the support roller 41 allows the paperboard to smoothly enter between the multiple paper feeding rollers 8 and smoothly move out from between the multiple paper feeding rollers 8.

The upper rotating shaft 4 drives the corresponding lower rotating shaft 5 to rotate in opposite directions through the two adjacent second gears 10, and the second gear 10 drives the corresponding support shaft 7 to rotate through the first gear 9, so that the two adjacent paper feeding rollers 8 can rotate in opposite directions, and the paper board is transported by the paper feeding rollers 8. When the oscillator drives the two adjacent rotating seats 6 to swing in opposite directions relative to the upper rotating shaft 4 and the lower rotating shaft 5, the support shaft 7 drives the first gear 9 to rotate in the opposite direction. The adjacent second gear 10 rolls on the oscillator, and the two adjacent rotating seats 6 are driven to swing. After adjusting the position of the paper feed roller 8, the driving roller 12 can still drive several paper feed rollers 8 to rotate synchronously. The staff drives the first movable plate 23 and the stop block 24 to move upward, and the first compression spring 26 is in a compressed state, so that the stop block 24 is no longer in contact with the support block 20, thereby releasing the limit on the position of the support block 20. The staff drives the servo motor 15 and the motor seat 17 to move, and the motor seat 17 drives the support block 20 to move synchronously, so that the end of the positioning column 19 is out of the positioning groove 21, and the fourth gear 16 is no longer engaged with the third gear 14, and the removal of the servo motor 15 is completed.

[0050] The adjustment plate 27 is driven to move by the first hydraulic telescopic rod 28, and the adjustment plate 27 slides relative to the support plate 32. The design of the support plate 32 allows the adjustment plate 27 to move smoothly relative to the support box 2. The adjustment plate 27 drives several tooth plates 31 to move, and two adjacent tooth plates 31 respectively drive the corresponding two fifth gears 29 to rotate in different directions. The fifth gear 29 can drive the rotating seat 6 to swing through the first connecting frame 30, and the rotating seat 6 drives the support shaft 7 and the paper feeding roller 8 to move, thereby changing the distance between the two adjacent paper feeding rollers 8. The third movable plate 55 is driven to move in the vertical direction by the fourth hydraulic telescopic rod 56, thereby changing the distance between the third movable plate 55 and the second friction plate 50, adjusting the length of the second compression spring 57, and then controlling the second compression spring 57. The pressure exerted by the compression spring 57 on the second friction plate 50 changes the friction force between the second friction plate 50 and the first friction plate 49, and the second movable plate 36 is driven to translate by the second hydraulic telescopic rod 38. The second movable plate 36 drives the second friction plate 50 to translate through the guide sleeve 54. The second friction plate 50 drives the first friction plate 49 and the first movable seat 33 to move relative to the paper feeding table 1 through the friction force, so that the two first movable seats 33 move toward the conveyed cardboard. The first movable seat 33 drives the slider 52 to slide relative to the support frame 51. When the cardboard tilts, one of the rotating plates 34 above the first movable seat 33 tilts, and several first correcting rollers 47 on the rotating plate 34 respectively abut against the cardboard. As the first movable seat 33 continues to move, the first movable seat 33 is rotated. The first deflection-correcting roller 47 on the rotating plate 34 pushes the cardboard to move, and the first deflection-correcting roller 47 corrects the cardboard until the second deflection-correcting roller 48 on the first movable seat 33 is in contact with the cardboard, and the first deflection-correcting roller 47 and the second deflection-correcting roller 48 are in the same straight line again. The cardboard supports the second deflection-correcting roller 48 and the first movable seat 33. As the second friction plate 50 continues to translate, the second friction plate 50 cannot drive the first friction plate 49 to move synchronously by friction. The second friction plate 50 slides relative to the first friction plate 49. After the cardboard is corrected, the first movable seat 33 automatically stops moving. When the second friction plate 50 moves to the preset position, the second hydraulic telescopic rod 38 drives the second movable plate 36 to move in the opposite direction, and the second friction plate 50 again The first friction plate 49 and the first movable seat 33 are driven to move in opposite directions by friction force. When the first movable seat 33 and the stop plate 53 abut against each other, the first movable seat 33 and the first friction plate 49 are reset to the initial position relative to the paper feeding table 1. As the second movable plate 36 continues to move, the second friction plate 50 slides relative to the first friction plate 49 until the second movable plate 36 and the second friction plate 50 move to the initial position. Cardboards of different specifications can be corrected, thereby improving the scope of application. The design of the support roller 41 allows the cardboard to smoothly enter between the multiple paper feeding rollers 8 and smoothly move out from between the multiple paper feeding rollers 8. The second connecting frame 44 and the second movable seat 40 are driven to move in the vertical direction by the third hydraulic telescopic rod 43.The second movable seat 40 can drive the support roller 41 to move vertically through the second support portion 42 to change the initial height of the support roller 41.
