An air inlet pipe 22 is fixedly connected to one end face of the preheating roller 2, the air inlet pipe 22 penetrates through a support frame 1 and is communicated with the interior of the preheating roller 2, and a steam generating mechanism (not shown in the figure) is connected to one end, far away from the preheating roller 2, of the air inlet pipe 22. The preheating roller 2 is made of heat conducting materials.

The upper side of the preheating roller 2 is provided with a first adjusting roller 3, and a gap exists between the first adjusting roller 3 and the preheating roller 2. The lower side of the preheating roller 2 is provided with a second adjusting roller 4, a gap also exists between the second adjusting roller 4 and the preheating roller 2, and the axes of the preheating roller 2, the first adjusting roller 3 and the second adjusting roller 4 are respectively parallel to each other. The corrugated medium is transferred from the side of the preheating roll 2 close to the first regulating roll 3 to the direction close to the preheating roll 2, and then the corrugated medium passes through the gap between the first regulating roll 3 and the preheating roll 2, then passes through the gap between the preheating roll 2 and the second regulating roll 4 around the preheating roll 2, and moves in the direction away from the preheating roll 2.

When preheating corrugated medium, generate thematic steam through steam generation mechanism, steam gets into inside preheating roller 2 along intake pipe 22 afterwards, corrugated medium walks around preheating roller 2 and moves to the direction of keeping away from preheating roller 2, and at this in-process, preheating roller 2 carries out the drying to corrugated medium, can improve corrugated medium's roughness, corrugated medium after the drying is better at the quality of follow-up carrying out the bonding, and it is comparatively simple to the structure that corrugated medium preheats, be convenient for operate and save the resource.

The first adjusting roller 3 is connected with a driving mechanism 5, and the driving mechanism 5 drives the first adjusting roller 3 to rotate around the axis of the preheating roller 2. So first adjusting roller 3 can adjust the area increase or the reduction that the corrugated medium walked around preheating roller 2 when rotating around the axle center of preheating roller 2, is convenient for adjust the drying degree of corrugated medium.

The driving mechanism 5 comprises two first gears 51 and two second gears 52, the two first gears 51 are respectively located at two sides of the preheating roller 2, each supporting roller 21 penetrates through the axle center of the corresponding first gear 51, and the supporting rollers 21 are rotatably connected with the first gears 51. A second gear 52 is disposed below each first gear 51, and each first gear 51 is engaged with the corresponding second gear 52.

A connecting roller 53 is fixedly connected between the two second gears 52, two ends of the connecting roller 53 respectively penetrate through the second gears 52 and are rotatably connected with the corresponding support frame 1, and one end of the connecting roller 53 penetrates through the support frame 1 and is fixedly connected with an output shaft of a servo motor 54.
