[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4A pressing roller with heating and cooling functions comprises a pressing roller body 1 and a supporting assembly, wherein a cavity is arranged in the pressing roller body 1, a connecting pipe 2 which is in communication with the cavity is arranged on one side of the pressing roller body 1, the supporting assembly comprises a bearing 3, a sealing member 4, a water inlet pipe 5 and a water outlet pipe 6, the sealing member 4 is T-shaped, the large end of the sealing member 4 is provided with the bearing 3, one end of the sealing member 4 is connected to the inner ring of the bearing 3, the outer ring of the bearing 3 is connected to the inner wall of the connecting pipe 2, the inner wall of the connecting pipe 2 is provided with a groove which is adapted to the sealing member 4 with the bearing 3, and the water inlet pipe 5 and the water outlet pipe 6 are arranged on the sealing member 4.
[0023] The big end of the seal 4 is connected to the connecting pipe 2 of the roller body 1 through the bearing 3. The seal 4 is T-shaped. A groove adapted to the seal 4 with the bearing 3 is arranged in the connecting pipe 2. The groove is also T-shaped. The water inlet pipe 5 and the water outlet pipe 6 pass through the seal 4. The water inlet pipe 5 is connected to an external heat source, and then the pressure roller can be heated by the reflux through the water outlet pipe 6. The water inlet pipe 5 is connected to an external cold source, and then the pressure roller can be cooled by the reflux through the water outlet pipe 6. It is easy to use.
