[0024] Specifically, by designing the atomizing nozzle 21 into a two-layer structure, the upper layer is mainly used for humidifying and steam action on the upper layer of the paperboard, and the lower layer is for the middle layer of the paperboard. Each layer is equipped with independent steam injection pipeline and nozzle, and the two-layer spraying has a synergistic effect on the preheating of the glue at the corrugated paper peak. The upper spraying makes the steam diffuse on the surface of the paper, preliminarily raises the temperature of the glue, and creates a foundation for further deep preheating by the lower spraying. When the steam acts on the glue through the lower spraying, since the glue has been preliminarily heated by the upper spraying, it can more quickly absorb the heat brought by the lower spraying, and accelerate the gelatinization process of the starch glue. In the production process of the seven-layer board with high grammage material, this double preheating mechanism can ensure that the glue at the corrugated paper peak of the middle layer and the upper layer reaches the ideal gelatinization state quickly, speeds up the bonding speed of the upper single-sided corrugated paper and the middle separator paper, and further significantly improves the production efficiency, realizes the speed increase from 50 m / min to 80 m / min.

[0027] In detail, when the paperboard is at the position before entering the steam device, the real-time width of the paperboard can be accurately measured by the sensor arranged for detecting the width of the paperboard, when the paperboard passes through the sensor, the sensor generates a corresponding electrical signal, the signal represents the width information of the paperboard, then the sensor transmits the obtained paperboard width signal to the PLC, the PLC internally prewrites a corresponding control program to drive the second motor 35 to rotate, the output end of the second motor 35 drives the rotating shaft 34 to rotate, since the rotating shaft 34 and the second bidirectional screw rod 32 are both fixedly installed with the meshed bevel gears 33, so the rotation of the rotating shaft 34 is transmitted through the meshing of the bevel gears 33, and drives the second bidirectional screw rod 32 to synchronously rotate.
