The invention belongs to the field of spinning and discloses a spinning oiling device and a control method. The spinning oiling device comprises a body, the body is provided with a cavity, and the cavity is filled with oil mist. When fibers for spinning pass through the cavity, the oil mist in the cavity oils the passing fibers. The cavity is divided into an oil mist concentration zone filled withthe oil mist and a fiber oiling zone through which the fibers pass, the oil mist concentration zone is communicated with the fiber oiling zone, and the oil mist in the oil mist concentration zone enters the fiber oiling zone to oil the fibers passing through the fiber oiling zone. A novel spinning oiling concept is provided; through a non-contact oil mist oiling mode, the difference of the oilingquantity of a single fiber in a bundle of fibers within oiling time can be effectively reduced, the spinning process tension in a spinning process is improved, and the quality of the fibers is improved.
