In the above technical solution, the corrugated paper is placed on the conveying roller 10, and the motor is operated, and the output shaft thereof rotates and drives the conveying roller to rotate through the gear and the chain. The corrugated paper is moved forward as the transfer roller 10 rotates, and when the corrugated paper is moved to a position where line pressing is required, the ultrasonic humidifying device is turned on. The ultrasonic humidifier 20 pressurizes the steam generated by the ultrasonic humidifier by passing the steam through a steam booster pump 22, and then the steam is passed through a hose to a plurality of nozzles 24 to humidify the corrugated paper. During the humidification process, the air cylinder 29 is opened to push the support plate 25, and the roller 26 on the support plate 25 moves linearly in the groove 28 on the support plate 27. The supporting plate 25 moves to drive the nozzles 24 on the supporting plate to do linear motion in the width direction of the corrugated paper, so that the positions of the corrugated paper, which need to be pressed with the lines, are uniformly and comprehensively humidified.

However, it will be appreciated by those skilled in the art that various modifications may be made to the burst resistant corrugated paper dual line pressing apparatus of the present invention as set forth above without departing from the spirit of the invention. Accordingly, the scope of the invention should be determined from the following claims.
