The invention discloses efficient board grinding equipment. The efficient board grinding equipment comprises a base and a belt, wherein the left side of the top of the base is fixedly connected with afirst electric telescopic rod, the right end of the first electric telescopic rod is fixedly connected with a movable seat, a second electric telescopic rod is fixedly connected to the left side of the movable seat, a clamping plate is fixedly connected to the top of the second electric telescopic rod, a board is arranged between the clamping plate and the movable seat, a longitudinal sliding groove is formed in the top of the right side of the base, the inner cavity of the longitudinal sliding groove is connected with a sliding plate in a sliding mode, the two sides of the sliding plate aremovably connected with pulleys through rotating shafts, and the top of the sliding plate is fixedly connected with a connecting rod. According to the efficient board grinding equipment, a vertical rodcan be rotated, the vertical rod drives the grinding discs to rotate, the two grinding discs at the upper part and the lower part of the board rotate simultaneously, and the grinding discs can move longitudinally, so that the function of simultaneously polishing the top and the bottom of the board is achieved, the grinding efficiency of the board is greatly improved, and people can conveniently use the board.
