In the process of the enameled wire being pulled outward, the excess lubricating oil on the surface of the enameled wire can be scraped off by the scraping blade, so as to achieve the purpose of evenly distributing the lubricating oil on the surface of the enameled wire. Then, the lubricating oil flows into the inside of the lubricating oil box through the threading cover, so as to achieve the purpose of recovering the lubricating oil, and solves the problem that the second oiling wheel of the existing device does not directly contact with the lubricating oil, which easily leads to uneven distribution of the lubricating oil applied to the upper and lower parts of the enameled wire;

[0014] 2. The surface of the enameled wire used in the production of the enameled wire is coated with oil. By setting the surfaces of the first roller and the second roller to be concave from both ends to the middle, the enameled wire passing around the surface can be limited to prevent the enameled wire from falling off the first roller or the second roller.
