Adjusting mechanism of calendering and embossing device

An adjusting mechanism of a calendering and embossing device is characterized in that a pair of air bags is positioned at two ends of a movable roll support to push a movable roll downwards; another air bag is positioned in the middle of the movable roll support to lift the movable roll upwards; a wedge-shaped block and an adjusting screw rod are installed between the lower surface of a movable roll bearing block and the upper surface of a U-shaped groove of the support; and a wedge gib and adjusting screw are installed between the lateral side of the movable roll bearing block and a lateral side guide rail of the U-shaped groove of the support. The adjusting screw drives the wedge gib to move up and down to adjust gap between the support and the movable roll bearing block. The adjusting screw rod drives the wedge-shaped block to move horizontally to lead the movable roll to move up and down so as to finely adjust clearance between the movable roll and a fixed roll.
