Background In recent years, with the development of industries such as low-altitude economy, intelligent robots, wearable equipment, electric automobiles, consumer electronics and the like, the market demand for high-quality and low-cost metal foils has been rapidly rising. In the rolling production of metal foil, the process lubrication and cooling are generally carried out by adopting rolling oil, so that more rolling oil remains on the rolled foil. The residual quantity of rolling oil not only affects the rolling speed and reduces the production efficiency, but also causes the defects of easy production of sliding belts, coiling quality, crease and the like, and the residual quantity of the residual oil also affects the subsequent procedures of cleaning, annealing and the like. Therefore, oil removal is an important process in foil production, and rolling oil on the foil is removed by adopting an oil squeezing or blowing mode. When the shape of the metal foil is not good, the oil squeezing effect is poor, the oil removal of the foil depends on the blowing effect, the blowing oil removal effect is related to wind pressure and wind quantity, and when the residual oil is more, the wind pressure and wind quantity are required to be larger.
