A number of support legs 45 are fixedly connected to the bottom of the paper feeding table 1. The translation structure includes a second movable plate 36 arranged below the second friction plate 50.

[0024] Working principle: According to the thickness of the cardboard, the pendulator drives two adjacent rotating seats 6 to swing in opposite directions relative to the upper rotating shaft 4 and the lower rotating shaft 5 respectively. The rotating seat 6 drives the support shaft 7 to slide relative to the avoidance hole 46, so that the distance between two adjacent paper feeding rollers 8 is set to a preset value. A plurality of support shafts 7 are driven to rotate through a synchronous drive structure, so that the support shafts 7 drive a plurality of paper feeding rollers 8 to convey the cardboard. And the cardboard is rectified through a rectifying mechanism, so that the cardboard is conveyed centered relative to the paper feeding rollers 8, which is convenient for conveying cardboard of different specifications according to actual needs, improving the applicable range, and can convey the cardboard centered, reducing the possibility of deviation in the printing position and ensuring the printing quality; The servo motor 15 drives the fourth gear 16 to rotate, the fourth gear 16 drives the third gear 14 to rotate, the third gear 14 drives the driving roller 12 and the first bevel gear 11 to rotate.

When the pendulator drives two adjacent rotating seats 6 to swing in opposite directions relative to the upper rotating shaft 4 and the lower rotating shaft 5 respectively, the support shaft 7 drives the first gear 9 to roll on the adjacent second gear 10. After the pendulator drives two adjacent rotating seats 6 to swing and adjusts the position of the paper feeding rollers 8, the driving roller 12 can still drive a plurality of paper feeding 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 no longer contacts the support block 20, releasing the limitation on the position of the support block 20. The staff drives the servo motor 15 and the motor base 17 to move, and the motor base 17 drives the support block 20 to move synchronously, so that the end of the positioning column 19 disengages from the positioning groove 21, and the fourth gear 16 no longer meshes with the third gear 14, and the removal of the servo motor 15 can be completed; Drive the adjustment plate 27 to move through the first hydraulic telescopic rod 28. The adjustment plate 27 slides relative to the support plate 32. Through the design of the support plate 32, the adjustment plate 27 can move stably relative to the support box 2. The adjustment plate 27 drives several toothed plates 31 to move. Two adjacent toothed plates 31 respectively drive two corresponding fifth gears 29 to rotate in opposite directions. The fifth gear 29 can drive the swing seat 6 to swing through the first connecting frame 30. The swing seat 6 drives the support shaft 7 and the paper feeding roller 8 to move, changing the distance between two adjacent paper feeding rollers 8. Drive the third movable plate 55 to move in the vertical direction through the fourth hydraulic telescopic rod 56, 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 further controlling the pressure exerted by the second compression spring 57 on the second friction plate 50, changing the friction force between the second friction plate 50 and the first friction plate 49. Drive the second movable plate 36 to translate through 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 towards the conveyed cardboard. The first movable seat 33 drives the slider 52 to slide relative to the support frame 51. When the cardboard is tilted, one of the rotating plates 34 above the first movable seat 33 is tilted, and several first deviation rectifying rollers 47 on the rotating plate 34 are respectively abutted against the cardboard. As the first movable seat 33 continues to move, the first deviation rectifying rollers 47 on the rotating plate 34 push the cardboard to move, and the first deviation rectifying rollers 47 correct the deviation of the cardboard until the second deviation rectifying rollers 48 on the first movable seat 33 are all in contact with the cardboard, and the first deviation rectifying rollers 47 and the second deviation rectifying rollers 48 are again on the same straight line. The cardboard supports the second deviation rectifying rollers 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 through the friction force, and 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 reverse direction, and the second friction plate 50 drives the first friction plate 49 and the first movable seat 33 to move in the reverse direction through the friction force again. When the first movable seat 33 abuts against the stop plate 53, the first movable seat 33 and the first friction plate 49 are reset to the initial position relative to the paper feeding table 1. And 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. It can correct the deviation of cardboard of different specifications, improving the applicable range. Through the design of the support roller 41, the cardboard can enter between several paper feeding rollers 8 stably and move out between several paper feeding rollers 8 stably. Drive the second connecting frame 44 and the second movable seat 40 to move in the vertical direction through the third hydraulic telescopic rod 43,The second movable seat 40 can drive the support roller 41 to move in the vertical direction through the second support portion 42, thereby changing the initial height of the support roller 41.
