The guide rollers in the first guide roller group 71 and the second guide roller group 73 are both arranged in three levels from top to bottom. Three-level inlets and outlets 7221 are arranged on both sides of the drying oven 72 from top to bottom. The coated substrate cooperates with the first-level inlet and outlet 7221 after passing through the first-level guide roller on the left side, cooperates with the second-level inlet and outlet 7221 after passing through the first and second-level guide rollers on the right side, cooperates with the third-level inlet and outlet 7221 after passing through the second and third-level wire conduits on the left side, and cooperates with the third-level guide roller on the right side after coming out from the right side of the third-level inlet and outlet 7221.

[0032] The drying device 7 is provided with a heating device 721 and a box body 722, and the inlet and outlet 7221 are arranged on both sides of the box body 722. The heating device 721 is provided with a heating chamber 7211 and an air distribution chamber 7216. A partition 7214 is provided between the heating chamber 7211 and the air distribution chamber 7216, and a connecting port 7215 is provided at one end of the partition 7214.

[0033] The principle of this utility model is:

[0034] When the utility model is in use, the substrate is installed on the unwinding device 3, and the substrate is wound in the winding device 9 after being pulled. The process involves existing conventional operating means, which will not be repeated here. Among them, the unwinding device 3 and the winding device 9 are existing ones, such as the air expansion shaft or hydraulic extrusion structure shown in the embodiment drawings. The utility model does not involve improvements in this aspect, so it will not be repeated.

[0035] The substrate coming out of the unwinding device 3 is subjected to constant tension control by the tension adjusting device 4. During the process, the tension detectors 43 on both sides of the tension adjusting roller 42 detect the change in tension (the tension detector 43 is already available and will not be described in detail), and then the angle between the connecting portion 41 and the table 2 is adjusted by the hydraulic device to achieve tension control, thereby ensuring that the tension of the substrate remains unchanged during the unwinding and rewinding process, thereby effectively ensuring the coating effect.

[0036] After the tension is adjusted by the tension adjusting device 4, the substrate is coated in the coating device 5. During the process, the coating device 5 is existing, and a comma scraper is used in the embodiment figure. However, for those skilled in the art, without departing from the core technical solution of the utility model, simple replacement of the coating device 5, such as slit coating, etc., should also fall within the protection scope of the utility model.

[0037] The coated substrate is folded back twice in the drying device 7, thereby forming three heating strokes, so that the length of the coating device 5 can be greatly reduced, thereby effectively reducing the volume of the equipment. The coated surface will change during the folding process, such as the attached Figure 3 As shown, the film-coated surface will rotate from the top to the bottom, and then rotate to the top, so the air outlet 7219 needs to be arranged accordingly to dry the film-coated surface, as shown in the attached Figure 5 The dotted line on the middle air distribution plate 7218 indicates the position of the coated surface corresponding to the air outlet hole 7219. The expanded diameter opening at the front end of the air outlet hole 7219 can achieve comprehensive air drying of the coated surface.
