Patent ID: 7883047

Claim:
A tension adjustment structure for a fabric winding machine driven by a driving mechanism to roll up a fabric and adjust the tension of the rolling fabric, comprising: a roller pivotally located on the fabric winding machine and coupled with the driving mechanism through a first transmission unit, the first transmission unit having two transmission wheels located respectively on the driving mechanism and the roller and a belt striding over the two transmission wheels to drive the roller to roll up the fabric; a fabric pressing mechanism having an action arm on the fabric winding machine and a fabric pressing bar located on the action arm, the fabric pressing bar having a first position not in contact with the fabric and a second position in contact with the fabric to be lifted upwards; and an adjustment mechanism including a brake member being in contact with the action arm, a pressing member corresponding to the belt and a linkage unit located between the brake member and the pressing member, the brake member being butted by the action arm while the fabric pressing bar is at the first position and the linkage unit driving the pressing member to butt the belt to increase the rolling tension; the fabric pressing bar being moved by the action arm at the second position to release the pressing member from the belt through the linkage unit.
