This utility model proposes a continuous production equipment for nickel-metal hydride battery electrodes, relating to the field of nickel-metal hydride battery electrode production technology. It includes a base, on which a shearing assembly and a conveying assembly are mounted, with the conveying assembly located to the left of the shearing assembly. This continuous production equipment for nickel-metal hydride battery electrodes operates by starting a first rotary motor to drive a turntable to rotate counterclockwise. The turntable drives a mounting block to rotate. When the inclined surface of the mounting block contacts a ball bearing at the bottom of a push rod, the ball bearing moves upward along the inclined surface of the mounting block. Simultaneously, the push rod drives the shearing blade upward, thus shearing the battery electrode. As the mounting block continues to rotate away from the ball bearing, the ball bearing falls under the influence of gravity, causing the shearing blade to fall until the next top block lifts the ball bearing. This achieves continuous shearing of the battery electrode while simultaneously reducing its structural complexity and cost.
