Abstract

The invention provides an aluminum foil double-face fast coating device. The aluminum foil double-face fast coating device comprises a first frame, an unwinding mechanism, a feeding drawing mechanism, a coating mechanism, a drying oven, a discharging drawing mechanism and a winding mechanism, wherein the unwinding mechanism, the feeding drawing mechanism, the coating mechanism, the drying oven, the discharging drawing mechanism and the winding mechanism are arranged on the first frame. The coating mechanism is a double-face ladder type coating mechanism which comprises a front side coating mechanism body and a back side coating mechanism body. The drying oven is a suspension drying oven. Aluminum foil sequentially passes through the unwinding mechanism, the feeding drawing mechanism, the coating mechanism, the drying oven, the discharging drawing mechanism and the winding mechanism, and then double-face coating is completed. An aluminum foil double-face fast coating method sequentially comprises the steps of unwinding, front side coating, back side coating, double-face drying and winding. According to the aluminum foil double-face fast coating device and method, through the ladder type one-time front side and back side coating and one-time double-face drying technologies, the material conveying path is greatly shortened, fast coating is achieved, the coating speed can reach 150m/min, in addition, the double faces are dried at a time after being coated, the space of the drying oven is saved, the manufacturing cost is reduced, meanwhile, energy is saved by about 160KW/h, and the aluminum foil double-face fast coating device and method are suitable for gravure coating and reverse kiss coating.

Description

technical field [0001] The invention relates to the technical field of gravure coating of aluminum foil, in particular to a device and method for double-sided rapid coating of aluminum foil. Background technique [0002] New energy lithium battery outer packaging aluminum-plastic composite film, before dry lamination, coat a layer of resin binder on the front and back of the aluminum foil, then laminate with PE film on one side, and laminate with nylon film on the other side, this one-time aluminum foil double-sided coating Cloth technology is still blank in our country. [0003] The double-sided rapid coating technology of aluminum foil proposed by the present invention proposes a ladder-type one-time front and back side coating and one-time double-sided drying technology. One of the coating technologies is that the feeding route is shorter than that of the front and back sides respectively. Cloth, drying separately shortens the feeding distance by 50 meters, and realizes ...
