This invention discloses a pressure roller adjustment mechanism for a winding device, comprising a mounting bracket, two adjustment components, two traction ropes, and a pressure roller
assembly. The two adjustment components are symmetrically arranged at both ends of the mounting bracket. One end of each traction
rope is fixedly or detachably mounted on an adjustment component, and the other end is mounted on one end of the pressure roller
assembly. During the winding process, the adjustment components control the pressure roller
assembly to always press against the tangent point of the foil roll through the two traction ropes. The pressure roller adjustment mechanism of the winding device, through the coordinated arrangement of the two adjustment components, two traction ropes, and pressure roller assembly, continuously controls the pressure roller assembly to press against the tangent point of the foil roll, ensuring that the foil roll is tightly wound and preventing uneven winding of the foil roll.
