In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: the TPU film to be dried is clamped and positioned by a splint, and the electric slide rail drives the slider to move the TPU film to be dried. After drying inside the baking oven, it moves between two first mounting plates, one end of the first connecting rod is connected to a first mounting plate, one side of the first mounting plate is connected to a fan, and the first mounting plate There are two fans, and the two first mounting plates and fans are opposite to each other. An air duct is provided inside the first mounting plate, and the air duct is located on the opposite side of the two first mounting plates.

The air outlet end of the exhaust fan 19 is sealed and connected to one side of the processing box 2 and communicates with the interior thereof. The air inlet end of the exhaust fan 19 is sealed and connected to one end of the exhaust pipe 18, and the other end of the exhaust pipe 18 is sealed and connected to the other end of multiple exhaust heads 16. The processing box 2 is connected to a wet sponge treatment layer 22 through a clamping plate 21. When the TPU film is cooled, the exhaust fan 19 will extract the gas in the cooling chamber 13 through the exhaust pipe 18 and the exhaust head 16, and transport it to the interior of the processing box 2, so that the wet sponge treatment layer 22 in the processing box 2 can process the gas extracted from the cooling chamber 13, thereby avoiding the odor generated during the baking of the TPU film being directly discharged into the working environment, and reducing the probability of the TPU film generating gas to pollute the environment during baking.
