A heating connection pipe 34 is fixedly connected inside the heating plate 31 and is connected to the external connection line 37.

[0033] A connecting wire 37 is fixedly connected to the external side of the heating connecting pipe 34. The connecting wire 37 is mainly responsible for connecting the heating connecting pipe 34 to the external heating system. A clamping roller 32 is rotatably connected to the external side of the heating plate 31. A clamping roller 33 is fixedly connected to the external side of the clamping roller 32. The clamping roller 32 and the clamping roller 33 are arranged in pairs on both sides of the heating plate 31.

Externally, the external support connecting block 39 is fixedly connected to the outside of the support control plate 1, the external connection line 37 is fixedly connected to the inside of the support control plate 1, the bottom of the heater 36 is fixedly connected to the support fixing plate 38, the support fixing plate 38 provides installation support for the heater 36, electromagnetic heating plate 35, clamping roller 1 32 and clamping roller 2 33 and other components, the external heating connecting pipe 34 is fixedly connected to the outside of the support fixing plate 38, the external electromagnetic heating plate 35 is fixedly connected to the outside of the support fixing plate 38, the external clamping roller 1 32 is rotatably connected to the outside of the support fixing plate 38, the external clamping roller 2 33 is rotatably connected to the outside of the support fixing plate 38, and the external support fixing plate 38 is fixedly connected to the outside of the support control plate 1.

[0034] Specifically, the arc-shaped steam heating plate device uses the support control plate 1 as a carrier and is equipped with a humidification and heating mechanism 3. In the heating mechanism 3, the arc-shaped heating plate 31 is attached to the paperboard conveying path, and the electromagnetic heating plate 35 and the heating connecting pipe 34 provide heat in coordination. The heater 36 drives the electromagnetic heating plate 35, and the connecting line 37 introduces external heat. The clamping roller fixes and conveys the paperboard.

A connecting water supply pipe 23 is also fixedly connected to the outside of the water container 21, which is responsible for transporting the water in the water container 21 to the connecting sliding pipe 24. The support connecting block 22 and the water container 21 are both fixedly connected to the top of the support control plate 1.

Meanwhile, the clamping roller 2 33 and the clamping roller 1 32 provide support and fixation for the cardboard, ensuring that the position of the cardboard is fixed, thereby achieving the effect of heating to compensate for temperature and improve adhesion.

[0038] When water spraying for cooling or steam heating is required, the water inside the water container 21 can be pumped through the water supply pipe 23 into the connecting sliding pipe 24, and then sprayed out through the atomizing nozzle 25. At the same time, when the position of the connecting sliding pipe 24 needs to be adjusted, the position of the connecting sliding pipe 24 can be changed by sliding the supporting sliding block 27. Meanwhile, the supporting slide rail 26 provides support for the movement of the supporting sliding block 27, thereby ensuring the normal operation of the connecting sliding pipe 24 when the position is changed, thus achieving the effect of water spraying for cooling or steam heating.

[0039] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
