Under the reaction force of the spring, the pressure roller can elastically press on the fabric of the guide roller, thereby further improving the flatness and quality of the fabric.

[0017] Secondly, by using a crank to rotate the first rotating rod on the mounting frame, the sprocket on the first rotating rod engages with the sprocket on the second rotating rod via a chain. The rotation of the second rotating rod causes the outer second bevel gear to engage with the first bevel gear, allowing the screw connected to the first bevel gear to rotate in the side groove. Since the two screws rotate synchronously on the mounting frame, the protrusions connected to the threads on the outer sides of the screws can slide in the side groove. The protrusions of the two protrusions are rotatably connected to the end of the same adjusting rubber roller, allowing the adjusting rubber roller to adjust and apply pressure to the fabric, thereby better tightening the fabric during the winding and conveying process and effectively preventing wrinkles.
