Description

Technical Field

[0001] This utility model relates to the field of thin film coating technology, specifically a drying device provided in a thermally conductive and flame-retardant thin film coating apparatus. Background Technology

[0002] The thermally conductive and flame-retardant film coating apparatus is a device specifically designed to uniformly and precisely coat the surface of flexible substrates (such as PI film, PET film, copper foil, aluminum foil, etc.) with a functional coating that combines high thermal conductivity and excellent flame-retardant properties. After coating, a drying device is required to dry the film.

[0003] However, existing drying devices typically use fans to blow hot air to dry film coatings. When the fan draws in air, if the surrounding air is humid, the airflow drawn in by the fan carries a lot of moisture, which will cause some steam to be blown out when the airflow turns into hot air. In addition, most drying devices can only dry one side of the film, affecting the drying effect of the film coating. Therefore, they do not meet the existing requirements. To address this, we propose a drying device for thermally conductive and flame-retardant film coating devices. Utility Model Content

In addition, most drying devices can only dry one side of the film, which affects the drying effect of the film coating.

[0024] A first motor is installed on the rear end face of one of the U-shaped plates 1.
