Two sets of cloth turning mechanisms are symmetrically provided in the cloth inlet channel. When the cloth passes through the cloth outlet channel, the fan sprays high-pressure gas to blow the cloth into a rope shape. A cloth turning mechanism is provided, and the cloth brushing roller is used to rub the cloth to break up the rope-shaped cloth to avoid uneven dyeing. By providing a dehydration mechanism, when the cloth dyeing is completed, one end of the cloth is pulled out of the cylinder body and the cloth is wound around the cloth winding roller. The cloth winding roller rotates and drives the cloth to move, and then one end of the cloth is wound between the upper squeezing roller and the lower squeezing roller.
