Description

Technical Field

[0001] The present application relates to the field of polyester spinning process production, and in particular to an oiling device suitable for polyester ultrafine fibers. Background Art

[0002] Polyester microfiber is a synthetic fiber made from polyester compounds through spinning, stretching and other processes. Its diameter is thinner than ordinary fibers, so it has a higher specific surface area and better softness, hygroscopicity, air permeability and other characteristics. In the spinning production process of hollow or cotton fibers, oiling is an important step in the spinning process. Proper oiling can increase the bundling of the yarns and reduce the friction coefficient. The distance from the spinneret to the winding machine generally involves many rollers and wire guides, which reduces the impact of friction on the yarn quality, has anti-static properties, and is convenient for weaving.

[0003] A Chinese patent with announcement number CN218932568U discloses an oiling device for DTY wire production, including an L-shaped frame, a first motor, a second gear, a first gear, a rotating rod, a first oiling roller, a supporting frame, an oil tank, an oil outlet pump, a connecting pipe, an oil spray head, a second oiling roller and a connecting frame. When in use, oil can be sprayed onto the first oiling roller and the second oiling roller by starting the oil outlet pump.

[0004] During the use of the above technology, since the position of the oil spray head is fixed and the oil spray head can only oil the first oil coating roller at the top, the second oil coating roller at the bottom cannot directly contact the oil, and the amount of oil sprayed by the oil spray head on the first oil coating roller along its axial direction also varies, resulting in uneven oiling of the DTY wire at different positions on the axial direction of the first oil coating roller, which is obviously insufficient.
