Two pairs of rollers of the existing laminating device are of an up-and-down parallel structure, and the direction of a pole piece is in the horizontal direction. Because the two paired rollers are driven by the independent motors and the speed reducers which are arranged on the same side of the two paired rollers in the axial direction, the gravity centers of the paired rollers and the center line of the paired rollers are not on the same base line. When the roll needs to be lifted up due to the fact that the gravity point is not in the center position when the band needs to be threaded and the pole piece connecting band opening and the copper film blank area are avoided, the phenomenon that the roll is inclined can be caused only by lifting up the press roll through the return force of the pressurized gas-liquid pressurizing cylinder, and therefore an auxiliary device needs to be additionally added for correction.
