The invention discloses polyester coating equipment with a function of cleaning. The equipment comprises a base, an air drying mechanism, a dip-dying mechanism, a drying mechanism and a winding mechanism, wherein the drying mechanism comprises a first bracket, a second bracket, electric hot plates, a fifth drum and a sixth drum; the electric hot plates are fixed between the first bracket and the second bracket; the winding mechanism comprises a support plate, a motor, a motor shaft, a rotary rack, a winding drum, a hydraulic cylinder, a piston rod, a limit sleeve and a fourth bolt; and the rotary rack is put on the piston rod by running through the winding drum. In the polyester coating equipment with the function of cleaning, the winding drum can rotation along with the rotation of the rotary rack to facilitate automatic winding of polyester fabrics, and at the same time, a first drum, a second drum, a third drum, a fourth drum, the fifth drum and the sixth drum rotate to assist the polyester fabrics to move rightwards, which facilitates the orderly completion of cleaning, air drying, dip-dying, drying and winding processes of the polyester fabrics, and makes the whole operation more well-organized and efficient.
