A slitting machine unwinding structure

Abstract

This utility model relates to the field of slitting machine technology, specifically to a slitting machine unwinding structure, including a machine support frame. An unwinding assembly is located at the right end of the machine support frame. The unwinding assembly includes an unwinding roller, a first gear, a servo motor, a first sprocket, a second gear, a support frame, a lifting plate, a pressure roller, a second sprocket, a first limiting rod, a first spring, a third sprocket, and a transmission chain. The transmission chain is connected to the first, second, and third sprockets. The second gear meshes with the first gear. A roll of nonwoven fabric is fitted onto the surface of the unwinding roller. The pressure roller presses the nonwoven fabric roll tightly. The servo motor, the first gear, and the second gear work together to drive the unwinding roller to rotate counterclockwise, unwinding the nonwoven fabric roll. Simultaneously, the transmission chain, the first sprocket, the second sprocket, and the third sprocket work together to drive the pressure roller to rotate clockwise, causing the pressure roller to rotate synchronously with the nonwoven fabric roll, thereby avoiding wear on the nonwoven fabric and improving the tensioning effect of the nonwoven fabric.
