Uniform oil coating device and oil coating method for enameled wire production

Abstract

The invention relates to the technical field of varnished wire production, in particular to a uniform oiling device and method for varnished wire production, an oiling mechanism and an oil wiping mechanism are sequentially arranged in the conveying direction of varnished wires, the oiling mechanism is provided with an oil pool and a rotatable oil roller in the oil pool, and the varnished wires are tangent to the oil roller and can be dipped in lubricating oil; the oil scraping mechanism is characterized in that the circumferential surfaces of two clamping wheels abut against each other, an oil scraping opening is formed between the two clamping wheels, the clamping wheels are driven by a rotary driving assembly to rotate, flexible oil scraping sleeves are sleeved on the wheels and abut against each other to clamp enameled wires, an adjusting assembly is additionally arranged to adjust the distance between the clamping wheels to adapt to different wire diameters, extrusion wheels are matched with the clamping wheels, and the distance between the extrusion wheels and the clamping wheels is smaller than the thickness of the oil scraping sleeves. When the squeezing wheel rotates along with the clamping wheel, oil in the oil wiping sleeve can be squeezed out, so that the oil coating mechanism firstly enables the enameled wire to be fully dipped in oil, the rotating clamping wheel scrapes redundant oil through the oil wiping sleeve, the squeezing wheel maintains the adsorption force of the oil wiping sleeve, and the problem of adsorption saturation of an existing oil scraping device is solved.
