This invention discloses a drying system for printed and dyed fabrics. The invention relates to the field of printing and dyeing fabric drying technology and includes a steel frame and a control module. The steel frame has several staggered drying cylinders on its sidewalls. A moving mechanism is provided on the sidewall of the drying cylinder located on the fabric inlet side. The moving mechanism includes a moving stake for carrying a cleaning mechanism to move axially relative to the drying cylinder. The movement of the cleaning mechanism is achieved by a motor started by the control module. The cleaning mechanism includes a scraper, which has an X-shaped structure and is made of rubber. The side of the scraper closest to the drying cylinder is arc-shaped to conform to the surface of the drying cylinder. The scraper is used to clean the surface of the drying cylinder. This invention can trigger a deflection plate to momentarily deflect when the scraper moves to the end of its stroke, causing contaminants attached to the scraper surface to be quickly ejected. It has the characteristic of achieving efficient online removal of oil film on the surface of the drying cylinder without affecting the continuous operation of the equipment.
