Self-adaptive wind field partition device for thin film production line

The invention discloses a self-adaptive wind field partition device for a film production line, which is characterized in that an upper support beam and a lower support beam are respectively and fixedly arranged at an interval up and down, an upper fixed wind shield and a lower fixed wind shield are respectively and fixedly arranged on the upper support beam and the lower support beam, and a strip-shaped aperture for a film to pass through is reserved between the upper fixed wind shield and the lower fixed wind shield; in order to enable the length of the aperture to be adaptively adjusted according to the real-time width of the film, two sliding wind shielding devices are arranged and are fixedly connected with the film stretching track trolleys on the two sides in the film production line, and the sliding wind shielding devices move along with the film stretching track trolleys on the two sides in the film production line. The upper fixing wind shield can slide relative to the upper supporting beam and the
