The whole device is powered by an external power supply. After the power-on is completed, the motor group 644, the heater 54, and the driving roller 9 work simultaneously. During the operation of the driving roller 9, it drives the conveyor belt surface 61 to rotate at a constant speed. The air blower group 644 blows the exhaust air into the distribution cavity 57 through the reserved hole 55 and the through hole 56.

Step Ⅲ: The first tension balance mechanism 5 cooperates with the second tension balance mechanism 6 to uniformly adjust the tension of the explosion-proof aluminum foil 4. When the explosion-proof aluminum foil 4 enters the first tension balance mechanism 5, the air blown from the air supply ports 52 to both sides can blow the two sides of the explosion-proof aluminum foil 4 flat, thereby preventing wrinkles from occurring during the printing process and ensuring the printing quality. Moreover, during the blowing process, the air heated by the heater 54 can heat the surface of the explosion-proof aluminum foil 4, thereby increasing the drying speed after printing the explosion-proof aluminum foil 4 and further improving the printing quality. During the process of the explosion-proof aluminum foil 4 passing through the second tension balance mechanism 6, the internal negative pressure mechanism 64 will make the two sides of the explosion-proof aluminum foil 4 closely adhere to the two sides of the conveyor belt surface 61. At the same time, during the rotation of the conveyor belt surface 61, the inclined guide rod 63 will pull the explosion-proof aluminum foil 4 to be slightly stretched to both sides, further ensuring that the explosion-proof aluminum foil 4 is in a state of uniform tension during the conveying process. Step Ⅳ: The explosion-proof aluminum foil 4 enters between the printing rollers 3 for printing. During the process of the explosion-proof aluminum foil 4 with uniform tension passing between the printing rollers 3, the printing machine case 2 controls the printing rollers 3 to perform printing treatment on the surface of the explosion-proof aluminum foil 4 to complete the printing process. Step Ⅴ: Unloading. The printed explosion-proof aluminum foil 4 is wound up through the receiving device for storage.
