The invention discloses a novel wringing roller changing device. The novel wringing roller changing device comprises a shaft head fixing mechanism, a hoisting beam and a dragging mechanism driven by a crown block, wherein the shaft head fixing mechanism is fixedly installed on one end of the hoisting beam, and the other end of the hoisting beam is provided with a balancing weight; the dragging end of the dragging mechanism is connected with the hoisting beam; the shaft head fixing mechanism comprises a control rod, an upper clamping mold, a lower clamping mold, an upper clamping mold base and a lower clamping mold base, wherein the upper clamping mold base and the lower clamping mold base are arranged in parallel vertically; one ends of the upper clamping mold base and the lower clamping mold base are fixed on a support; the free end of the lower clamping mold base extends out of the edge of the free end of the upper clamping mold base; the lower surface of the free end of the upper clamping mold base is fixedly connected with the upper clamping mold which is provided with a semi-circular groove; the semi-circular groove is matched with the outer periphery surface of a shaft head of a wringing roller; the upper surface of the free end of the lower clamping mold base is fixedly connected with the lower clamping mold which is provided with another semi-circular groove; the another semi-circular groove is matched with the outer periphery surface of the shaft head of the wringing roller. According to the device, the roller changing efficiency is improved, and labor and material resources are saved.
