[0034] Subsequently, the user operates the control button 101 again, so that the control button 101 controls the rotation motor 402 on the surface of the support frame 403 to work. Under the action of the rotation motor 402, the winding roller 401 is driven to rotate on the surface of the support frame 403. Under the action of the winding roller 401, the dyed polyester yarn body 110 is wound. Under the action of the frame body 405, the winding roller 401 is supported. After the winding is completed, the user loosens the mounting screw 404 on the surface of the support frame 403, removes the winding roller 401 from the surface of the frame body 405, and replaces the winding roller 401 to realize the automatic winding function of the dyed polyester yarn body 110 by the production line.
