[0032] The method of using a blower 210 to generate air and using a PTC heater 161 to heat the air source to dry the aluminum-coated film body 130 is a conventional existing technology.

[0033] A condensation assembly is also provided on the front outer wall of the drying oven 100, which includes a condensation box 300.

[0034] Specifically, multiple limit frames 150 are rotatably connected to the inner walls on both sides of the first side with movable rollers 151, and multiple limit frames 170 are rotatably connected to the inner walls on both sides with movable rollers 171. Limit plates 172 are also fixedly connected to the outer walls on both sides of the second side with limit frames 170. Multiple limit plates 172 are rotatably connected to the inner walls with movable rollers 171 of the same structure. This is to reduce the excessive stretching and swaying of the aluminized film body 130 during the hot air blowing and drying process.

[0035] Furthermore, a PTC heater 161 is provided on the inner wall of the second fixed shell 160, and an air outlet 162 is provided on the top of the second fixed shell 160. A hot air outlet is provided on the outer wall of the air outlet 162. The first fixed shell 140 has the same structure as the second fixed shell 160, which facilitates heating the air source and discharging it evenly.

[0036] Furthermore, the top of the condenser box 300 is equipped with an exhaust fan 310, and the air inlet of multiple exhaust fans 310 is connected to an exhaust pipe. The ends of multiple exhaust pipes extend into the interior of the drying box 100 to facilitate the discharge of accumulated moisture inside.

[0037] Furthermore, multiple exhaust fans 310 are connected to condenser pipes 350 at their exhaust ends, and multiple condenser pipes 350 are connected to water collection tanks 360 at their ends.

[0038] It is worth noting that the water collection tank 360 is fixedly installed at the bottom of the inner cavity of the condensate box 300, and a water valve 330 is provided on the outer wall of the water collection tank 360 to facilitate the discharge of internal condensate and excess air.

[0039] In some embodiments, a drain pipe may be connected to the outer wall of the water valve 330 to collect condensate.

[0040] It is worth noting that an opening is provided on one side of the outer wall of the condenser box 300, and a connecting shell 340 is fixedly connected to one side of the outer wall of the condenser box 300 by screws. A metal perforated plate 320 is fixedly connected to the other side of the outer wall of the condenser box 300. A cooling vortex tube 342 is fixedly connected to one side of the outer wall of the connecting shell 340, and a through circular hole 341 is provided on the other side of the outer wall of the connecting shell 340.

[0041] In some embodiments: the cooling vortex tube 342 is prior art, which facilitates the use of an external compressed air source to generate a certain cold source, thereby cooling the condenser tube 350. The condenser tube 350 model can be AIRSTE VT-3009.

[0044] Working Principle: During use, the aluminized film body 130 can be wound around the outer wall of multiple rotating traction rollers 120. The wave-like winding method greatly increases the time the aluminized film body 130 remains in the drying chamber 100, thus improving the drying effect. Furthermore, the drying chamber 100 is equipped with multiple limiting frames 150 and 170, as well as multiple limiting plates 172. These limiting frames 150, 170, and 172 provide support for the aluminized film body, reducing the impact of the external blower 210 on the aluminized film body 130 during hot air drying with the PTC heater 161, thus reducing excessive pulling and swaying. During the drying process of the aluminized film body 130, the drying chamber 100... The internal moisture can be better utilized and discharged by the exhaust fan 310, allowing the high-temperature moisture to enter the multiple condenser tubes 350. The multiple cooling vortex tubes 342 on the outer wall of the connecting shell 340 can use an external compressed air source to generate cold air and blow it onto the outer wall of the multiple condenser tubes 350, thereby reducing the surface temperature of the condenser tubes 350 and rapidly condensing the high-temperature moisture. The condensed water can flow into the water collection tank 360 and be discharged through the water valve, thereby reducing the direct discharge of moisture and the resulting humidity in the environment, which would affect the drying efficiency of the drying device. Moreover, the device uses multiple condenser tubes 350 for condensation and cooling with cooling vortex tubes, which makes the condensation effect more rapid and reduces the possibility of excessively high moisture re-entering the drying chamber 100 for drying, thus affecting the drying efficiency.
