摘要
Disclosed is a pre-wound sheet cut-off mechanism of a thin material sheet winding device, including a first winding roller, a plurality of curved guide plates arranged at a predetermined distance below the first winding roller and distributed and spaced from each other by a predetermined distance along an axial direction of a shaft of the first winding roller, a plurality of pre-winding plates each coupled between adjacent curved guide plates, a second winding roller, and a rider roller. In a winding operation, a core is conveyed into a curved-guide-plate channel defined between the first winding roller and the curved guide plates to adhere to and pre-wind a thin material sheet that is conveyed to the first winding roller, and is thereafter transported to a winding nip to form a roll with the thin material sheet. The winding speed of the roll is reduced for preparing a next core to reach the pre-winding plates, accordingly, the thin material sheet is slacked, such that the slacked thin material sheet can be pre-wound, thereafter, the thin material sheet pre-wound continuously and the thin material sheet is gradually tensioned on the next core until the thin material sheet is torn apart.
