A cooling fan 8 is installed on the outer side wall of the body 6 by bolts at each U-shaped jet hood 4. After the cooling fan 8 is started, it will blow air to the upper and lower sides of the metal plate through the U-shaped jet hood 4, so as to achieve double-sided blowing and cooling of the metal plate. The top of the bracket 2 is located on both sides of the pump 11 and two waterproof electric push rods 1 are symmetrically fixed. The telescopic part of the waterproof electric push rod 1 is installed with a roller frame 12, and the bottom of the roller frame 12 is evenly distributed with pressure rollers 15. After the waterproof electric push rod 1 is started, the pressure roller 15 will be placed on the upper side of the cooling metal plate, so as to compress and straighten the metal plate when conveying during the cooling process of the metal plate.
