Novel thin film stretching and drying device

The invention discloses a novel thin film stretching and drying device which is characterized in that two sides of a drying and stretching roller of a drying and stretching device are respectively sleeved with a liquid baffle, and the upper ends and the lower ends of the two liquid baffles are respectively fixed by an upper adjusting frame and a lower adjusting frame in a supporting device. Through the arrangement of the liquid baffles, when the stretching and drying device is used for stretching and drying a thin film, the thick lug edges on the two side edges of the thin film are located on the outer sides of the two liquid baffles, and at the moment, even if the thick lug edges throw liquid in the stretching and drying process, due to the arrangement of the liquid baffles, the liquid cannot be splashed to the thin film on the inner sides of the liquid baffles, so that thin film defects are avoided, and the thin film quality is improved; and the stretching and drying device has the advantages of being simpl
