[0037] Working principle: When using the transmission structure to transmit cardboard, first place the cardboard on the conveyor belt 2 on the support frame 1, and then start the driver 3 through an external power supply to drive the conveyor belt 2 to move, so as to convey the cardboard. During the process of conveying the cardboard, when the cardboard passes through the inclined plate 42, under the guiding action of the inclined plate 42, it will move between the two limiting plates 43, and then under the drive of the conveyor belt 2, the cardboard continues to move. When the cardboard passes through the pressure roller 46, the pressure roller 46 will drive the slider 45 to slide on the surface of the fixed rod 47, and at the same time, the pressure roller 46 rotates on the surface of the slider 45, so as to limit the position of the cardboard and reduce the pressure on the cardboard as much as possible, and avoid damaging the cardboard as much as possible.

[0038] When it is necessary to convey cardboard of different sizes, first pull the pull plate 56 to drive the limit rod 55 to slide on the inner wall of the "L"-shaped plate 54, so that the limit rod 55 moves away from the connecting plate 51, releasing the restriction on the position of the connecting plate 51. Then move the side plate 41 to drive the positioning rod 53 to move away from the plug plate 52. Then move the side plate 41 to be replaced so that the positioning rod 53 approaches the plug plate 52. Release the pull plate 56. Under the action of the elastic force of the second spring 57, the pull plate 56 moves closer to the "L"-shaped plate 54 to restrict the position of the side plate 41, completing the replacement of the side plate 41, the inclined plate 42 and the limit plate 43. By setting the replacement device 5, when it is necessary to convey cardboard of different sizes, the limit device 4 can be removed from the support frame 1 and the limit plate 43 with an appropriate distance can be replaced, thereby improving the flexibility of the use of the conveying structure of the cardboard pasting device.
