Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. During the printing process, as the printing speed of the printing machine continues to increase, the rotation speed of the printing roller inside the printing machine is also getting higher and higher, thereby generating a lot of heat. If the heat is not dissipated in time, it will affect the printing quality and the service life of the printing roller.

[0003] Existing printing roller cooling methods usually include natural cooling during shutdown and online cooling of the cooling structure.
