The extension and retraction length of the first cylinder changes with the equilibrium point. The position of the first conveyor roller can be adaptively adjusted during the conveying process, ensuring that the paper and the first conveyor roller are always taut, effectively preventing wrinkles on the paper surface. The extension and retraction of the second cylinder drives one end of a swing arm to swing, causing the other end of the swing arm to swing and adjust the second conveyor roller. A pressure is set on the second cylinder. When the paper is subjected to external tension, the force exerted by the second conveyor roller on the paper surface and the pressure exerted by the second cylinder interact to achieve equilibrium. The extension and retraction length of the second cylinder changes with the equilibrium point. The position of the second conveyor roller can be adaptively adjusted during the conveying process, ensuring that the paper and the second conveyor roller are always taut, effectively preventing wrinkles on the paper surface.
