Anti-shaking back-up roll for coiled material

The utility model discloses an anti-shake back-up roll for coiled materials, which comprises a base, a buffer mechanism is arranged above the base, a side plate is arranged above the buffer mechanism, a support mechanism is arranged in the side plate, a limit mechanism is arranged above the side plate, and the limit mechanism is arranged above the support mechanism. Under the cooperation of the air cylinder, the lifting column, the supporting pad and the compression roller, the purpose of preventing the supporting roller from shaking in the vertical direction can be achieved, and therefore the actual production effect cannot be affected; the driving shaft, the transmission shaft, the supporting roller and the rotating shaft can be driven to rotate by starting the driving machine, the purpose of rotating the coiled material is achieved, the supporting roller is detachably connected with the transmission shaft and the rotating shaft and is convenient to disassemble, and therefore replacement of the supporting r
