In the paper feeding process, the power source drives the main shaft 101 to rotate through the gear set, and meanwhile, the main shaft 101 enables the rubber roller 200 to rotate in the opposite direction to the main shaft 101 through the transmission assembly 230, so that the paper board between the main shaft 101 and the rubber roller 200 is conveyed in a rolling mode. When the gap between the rubber roller 200 and the main shaft 101 needs to be adjusted due to the change of the thickness of the paper board, the driving unit 220 drives the two eccentric seats 210 to rotate on the frame 100, so that the position of the rubber roller 200 is changed under the driving of the eccentric seats 210, and the gap between the rubber roller 200 and the main shaft 101 is adjusted to adapt to the paper board conveying with different thicknesses.

Therefore, when the main shaft 101 is driven to rotate by the power source, the third gear 234 and the fourth gear 235 which are meshed with each other drive the rubber roller 200 to move and rotate, and the steering direction is opposite to the main shaft 101, so that the paperboard is conveyed in the rolling direction.
In the transmission process, the third gear 234 is arranged on the frame 100 through the supporting frame and is meshed with the fourth gear 235 fixedly arranged on the main shaft 101, so that the third gear 234 synchronously rotates when the main shaft 101 rotates, the end part of the rubber roll 200 is fixedly connected with the linkage unit 240 which is movably connected on the end surface of the third gear 234 in the radial direction, so that when the eccentric seat 210 rotates in a driving straight line of the driving unit 220, the axis of the rubber roll 200 is adjusted to change, thereby adjusting the gap between the rubber roll 200 and the main shaft 101, in the process, the end part of the rubber roll 200 passes through the through hole 233 of the supporting seat, the diameter of the through hole 233 is larger than the diameter of the end part of the rubber roll 200, and at the moment, the end part of the rubber roll 200 is fixedly connected with the linkage unit 240 which is movably connected on the end surface of the third gear 234 in the radial direction, so that the rubber roll 200 and the third gear 234 can be mutually connected through the linkage unit 240, and when the third gear 234 rotates in the axial direction, the rubber roll 200 can be driven by the linkage unit 240 to rotate coaxially, and the paper board can be conveyed under the condition of matching with the main shaft 101.
