[0003] In the drying aspect, the common method is to use a simple air heater to heat directly against the film. However, this approach often has the problem of uneven heating, resulting in local overbaking or insufficient baking of the film, affecting product quality. Moreover, single air heater air supply has limited airflow coverage, making it difficult to effectively bake the film overall, thereby reducing production efficiency and product pass rate.

Then, the air induced assembly provides power to cause the gas to enter the first air duct 6 and the second air duct 7. The gas enters the first air duct 6 and then enters multiple first connecting tubes 8. At this time, the heating tube 10 inside the first connecting tube 8 heats the air flow, thereby heating the air flow, so that the gas ejected from the first jet hole 9 has a temperature. The heated air flow is then sprayed onto the polyurethane film for baking. The provision of multiple first connecting tubes 8 can improve the baking effect. The polyurethane film is then transported to the cooling zone 4 through the conveying assembly. The gas enters the second air duct 7 and then enters multiple second connecting tubes 11. Since the external air temperature is lower than that of the drying zone 3, the low-temperature gas is sprayed onto the polyurethane film through the second jet hole 12, thereby cooling the polyurethane film. The provision of multiple second connecting tubes 11 improves the cooling effect. This device can integrate line drying and cooling, thereby improving the production efficiency of polyurethane film. At the same time, it has a simple structure, occupies a small area, and is convenient for subsequent installation and maintenance.
