AI Technical Summary
Existing gauze curtain retraction devices cannot guarantee the flatness of the gauze curtain during the retraction process, resulting in wrinkles and deformation of the gauze curtain, which affects the performance.
A gauze curtain take-up and take-down device including a take-up roller and a clamping roller is adopted. The take-up roller is driven to rotate by a drive unit, and the clamping roller is pushed to slide along a first direction by an elastic component, so that the clamping roller and the take-up roller clamp the gauze curtain to ensure the flatness of the gauze curtain.
This effectively prevents wrinkles and deformation of the gauze curtain after it is rolled up, ensuring the effectiveness of the gauze curtain and maintaining its flatness during the opening and closing process.
