The invention relates to a tension frame, in particular to a rolling-washing-machine closed tension frame, and belongs to the technical field of rolling washing machine devices. The rolling-washing-machine closed tension frame comprises a box wall plate, a cloth feeding guiding roller, a cloth discharging guiding roller, grooved wheel discs, adjusting air cylinders and swinging arms. A bearing base is fixed on the box wall plate, and a swinging-arm rotating shaft is rotationally connected in the bearing base; the two adjusting air cylinders are hinged to the left side and the right side of the box wall plate, the extending ends of the two adjusting air cylinders are connected with the left end and the right end of the swinging-arm rotating shaft through adjusting arms, the swinging arms are fixedly connected on the swinging-arm rotating shaft, and the front ends of the swinging arms are connected with the grooved wheel discs. According to the rolling-washing-machine closed tension frame, steam losses in device operating are reduced through the closed structure, and the technology temperature of cloth is guaranteed; meanwhile, the tension of the cloth is adjusted through the air-cylinder swinging arms, device operating is more stable and more reliable, operation is convenient, losses of accessories are greatly reduced, the device cost is reduced, and maintenance is more convenient.
