[0037] When gluing and pressing, the blower 4 can drive the outside air to enter the inside of the blower 4 through the groove 2 and the through hole 3, and finally be discharged by the blower 4. Through the operation of the blower 4, the cooling of the glue on the cardboard surface during gluing can be realized, so as to improve the later gluing and pressing efficiency and convenience.
