[0036] Preferably, the film rack 3 is used to place the newly scraped polymer film on the glass plate, the pump body 9 pumps the steam generated by the steam generating assembly 13 into the conduit 8, and the conduit 8 transmits the steam to the inside of the shell 4, the humidity sensor 6 is used to display the air humidity in the temperature sensor 7, and the temperature sensor 7 is used to display the air temperature in the shell 4. The fan 5 is used to start the fan 5 through the numerical feedback of the humidity sensor 6 and the temperature sensor 7 when the required temperature and humidity in the shell 4 are too high, and perform exhaust treatment in the shell 4;
[0037] Place the newly scraped flat film on a glass plate, open the lower door 2, and immediately place the newly scraped flat film on the film rack 3 in the housing 4, and check the film-making temperature and humidity in the lower housing 4 through the temperature sensor 7 and the humidity sensor 6;

[0039] Example 2
[0040] Please refer to the instruction manual Figure 1-6 As a preferred embodiment of the utility model, the steam generating assembly 13 is a cylindrical structure, and the inner wall of the steam generating assembly 13 extends to the center point and is sequentially provided with an inner cylinder 14, multiple sets of reinforcing ribs 15, multiple sets of heating fixing assemblies 16, heating belts 17, a water bucket 18 and a grid portion 19. The inner cylinder 14 is arranged between the steam generating assembly 13 and the multiple sets of reinforcing ribs 15. The diameter of the multiple sets of reinforcing ribs 15 is larger than the diameter of the inner cylinder 14. One side of the multiple sets of reinforcing ribs 15 penetrates the inner cylinder 14 and contacts the steam generating assembly 13.
