[0014] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0015] Example 1

[0016] See also Figure 1 and Figure 2 As shown, a printing drying device for decorative film processing involved in this embodiment comprises a drying cylinder 1 with a horizontal axis, an air inlet end cover 2 is provided at one end of the drying cylinder 1, and an air outlet end cover 3 is provided at the other end, the air inlet end cover 2 is provided with an air inlet 4, the air outlet end cover 3 is provided with an air outlet 5, an air duct 6 is connected between the air inlet 4 and the air outlet 5, a fan 7 for supplying air toward the air inlet is connected in series on the air duct 6, and an electric heating component 8 is provided in the air duct 6 at the air outlet of the fan 7, and the electric heating component 8 is a PTC heating element;

[0017] The drying cylinder 1 is provided with a first mesh plate 9 close to the air inlet end cover 2 and a second mesh plate 10 close to the air outlet end cover 3. A plurality of transmission rollers are rotatably connected between the second mesh plate 10 and the first mesh plate 9. The axis of the transmission roller is parallel to the axis of the drying cylinder 1. A material port 13 for the decorative film to enter and exit is opened on the side of the drying cylinder 1.
