Abstract
A tension adjustment structure for fabric winding machine includes a driving mechanism, a roller, a fabric pressing mechanism and an adjustment mechanism. The roller and the driving mechanism have corresponding transmission wheels strode by a belt. The driving mechanism drives the roller to roll up a fabric. The fabric pressing mechanism has an action arm and a fabric pressing bar located on the action arm. The fabric pressing bar has a first position without in contact with the fabric and a second position in contact with the fabric and lifted by the fabric. The adjustment mechanism is butted by the action arm when the fabric pressing bar is at the first position to butt the belt and increase initial rolling force of the roller. The action arm releases the belt while the fabric pressing bar is at the second position so that fabric rolling tightness can be controlled.
