The invention belongs to the technical field of gravure
coating for
lithium battery materials, and specifically relates to a double-sided high-speed gravure
coating device and a method for a
lithium battery. According to the double-sided high-speed gravure
coating device for the
lithium battery, coiled
lithium battery materials, that is,
aluminium foils or
copper foils, sequentially pass through an unwinding mechanism, a charging traction mechanism and a front-
surface coating mechanism from the left to right, then enter upwards a lower
drying box and pass downwards through a back-
surface coating mechanism, then pass upwards through an upper
drying box from the left to right, and then pass downwards through a discharging traction mechanism and are led to a winding mechanism for winding. According to the double-sided high-speed gravure coating device and method for the
lithium battery, a coating manner is changed into quantitative and same-direction high-speed coating adopting a cable from the original 'reverse coating adopting a micro-gravure roll', and the lengthened, high-temperature, high-air-quantity and energy-saving
drying boxes are used, thus the
drying time of the coated materials is shortened, and a
machine speed can achieve 120m / min for completing one-time double-sided high-speed coating.
