At the same time, the purified gas is returned to the drying mechanism 2 for reuse of hot air, thereby improving the drying effect of the drying mechanism 2.

[0023] like Figure 3 As shown, the drying mechanism 2 includes an air outlet plate 201, which is fixedly installed on the top of the inner cavity of the mounting cover 4. The bottom of the air outlet plate 201 is provided with evenly distributed air outlets. The top of the air outlet plate 201 is connected to a connecting pipe 202, and the top of the connecting pipe 202 is connected to a horizontal pipe 203. The right side of the surface of the horizontal pipe 203 is connected to a first cylinder 204. The first cylinder 204 is provided with a first ventilation motor 205, and the right side of the first cylinder 204 is connected to a heating box 206. The heating box 206 is provided with evenly distributed heating wires 207.

[0024] like Figure 3 As shown, a frame 208 is provided on the right side of the heating box 206. A filter screen 209 is fixedly installed on the inner side of the frame 208. Mounting side plates 210 are fixedly installed on both the front and back of the frame 208. The mounting side plates 210 are fixedly installed on the heating box 206 by mounting bolts.

[0025] The effects achieved by the above components are as follows: by setting up a filter screen 209 to filter the air entering the heating box 206, dust is prevented from adhering to the surface of the heating wire 207 and affecting the heating effect of the heating wire 207 on the air.

[0030] The above components achieve the following effect: by setting up activated carbon plate 305 and hydrated aluminosilicate plate 306, harmful substances generated during the drying of release agent are adsorbed and purified, preventing harmful substances from being released into the air and causing air pollution.

[0031] The working principle of a back coating device for laser film production:

[0032] The first ventilation motor 205 blows air into the interior of the horizontal tube 203. When the external air flows through the interior of the heating box 206, the heating wire 207 heats the incoming air. The hot air then enters the interior of the air outlet plate 201 through the connecting pipe 202, and is then blown evenly onto the surface of the laser film 7 through the air outlet at the bottom of the air outlet plate 201, thereby drying the release agent on the laser film 7.

[0033] The second ventilation motor 302 discharges the dried hot air inside the mounting cover 4 through the second cylinder 301, then introduces it into the purification box 304 through the air guide pipe 303, and then returns the hot air to the heating box 206 through the return pipe 307, thereby improving the heating efficiency of the air and improving the drying effect of the release agent on the laser film 7.
