Film winding device

The utility model relates to a thin film winding device which comprises a box body and a winding mechanism arranged on the box body, a heat dissipation plate is fixed on the top of the box body, an air blowing assembly used for blowing air to the heat dissipation plate is arranged on the box body, and an air outlet of the air blowing assembly faces the heat dissipation plate. A material guiding mechanism, a material guiding roller and a feeding roller are sequentially arranged on the side, away from the winding mechanism, of the box body from top to bottom. By arranging the air blowing assembly and the heat dissipation plate, a thin film firstly passes through the heat dissipation plate during winding, meanwhile, the air blowing assembly is used for blowing air to the thin film on the heat dissipation plate, the thin film is cooled, the thin film can be kept at a certain temperature during winding, the phenomenon that the thin film is wrinkled due to the too high temperature is avoided, and the winding qualit
