The invention provides a tension-adjustable two-roller active scutching device which comprises a rack, an integral frame, a transmission mechanism, an upper scutching roller and a lower scutching roller; the integral frame comprises a left fulcrum, a right fulcrum, a left lateral plate, a right lateral plate and a connecting prop; the middle parts of the left lateral plate and the right lateral plate are connected into a rigid integral by the connecting prop; the left fulcrum and the right fulcrum are respectively mounted at outsides of the left lateral plate and the right lateral plate, and respectively propped by a bearing seat and a worm gear reducer; the upper scutching roller and the lower scutching roller are mounted between the left lateral plate and the right lateral plate in symmetry with the connecting prop as the center; the transmission mechanism comprises a decelerating motor, an upper scutching roller gear, a lower scutching roller gear and transition gears; and the decelerating motor and the upper scutching roller gear are connected, the upper scutching roller gear mounted on the upper scutching roller is connected with the lower scutching roller gear mounted on the lower scutching roller via a pair of transition gears. The invention is reasonable in structure, convenient in operation, and simple in tension adjustment, the two rollers have equivalent speed and no tension difference, and the scutching and de-wrinkling effects are good.
