Rolling equipment for manufacturing substrate strip for cathode of nickel-metal hydride battery

The present invention discloses a nickel-hydrogen battery negative electrode produced by the rolling apparatus the strip substrate, comprising: a body, a winding system, drive system, control system, measurement system, cooling system and rolling system; each system provided at the body , the rolling system and the drive system drives; rolling system by a support roller disposed on the frame, two intermediate rolls, intermediate rolls and work rolls a configuration, two intermediate rolls and supporting rolls, the intermediate rolls are on a lower two, upper work roll, for the next two, upper, lower by two supporting rollers, two lower second intermediate rolls, an intermediate roller is enclosed in the outer two lower work rolls, work roll diameter is 17.5 to 18mm, the hardness of the work roll is 63 / 64HRc; winding tension of the winding system is 54kg ~ 1080kg. The device structure is simple, with the rolling pressure and the winding tension is provided by the specific work rolls, the rolling precision, the thickness of the negative electrode satisfy a nickel hydrogen battery with a steel strip substrate tape requirements.
