[0024] See also Figure 1-2 The present invention provides a technical solution for a roller with a heating function: it includes a roller body 1, and the two ends of the roller body 1 are respectively fixedly connected with a first end plate 3 and a second end plate 5, and the outer sides of the first end plate 3 and the second end plate 5 are respectively fixedly connected with a first rotating sleeve 2 and a second rotating sleeve 6, and the first rotating sleeve 2 is rotatably connected with an air inlet pipe 4 through a first sealing bearing 8, and the second rotating sleeve 6 is rotatably connected with an air outlet pipe 7 through a second sealing bearing 10.

[0025] The external heat source in this embodiment is selected as gas, which is heated by an electric heating wire and then connected to the air inlet pipe 4 using an air pump.

[0026] A heat storage ceramic 9 is installed inside the roller body 1. The two ends of the heat storage ceramic 9 are fixedly connected to the air inlet pipe 4 and the air outlet pipe 7 respectively. The heat storage ceramic 9 is set to be cylindrical. The diameter of the heat storage ceramic 9 is smaller than the inner diameter of the roller body 1, and a gap of 2-3 mm is set between the heat storage ceramic 9 and the roller body 1.

[0027] An air inlet hole 14 is formed at one end of the air inlet pipe 4 close to the heat storage ceramic 9 , and an air outlet hole 11 is formed at one end of the air outlet pipe 7 close to the heat storage ceramic 9 .
