[0002] In the production and processing of optical films, in order to avoid wrinkles on the optical films, they need to be flattened. Currently, when flattening the optical films, it is inconvenient to press and hold both ends of the optical films, which causes misalignment during flattening, resulting in low flattening effect and affecting the quality of the optical films.

[0003] The prior art patent CN219971369U discloses a flattening device for optical film production. The pressure plate is pulled so that the fixed ring squeezes the spring, causing the spring to deform. When the optical film is placed on the top surface of the placement table, the pressure plate is released so that the spring can be reset, and then the fixed ring drives the insertion rod to move, so that the pressure plate can press the two ends of the optical film, and then flatten it through the flattening roller.

[0004] However, in the aforementioned prior art, after pressing the two ends of the optical film, the two ends of the optical film cannot be retracted and adjusted, and cannot be stretched according to the length of the optical film. At this time, if the optical film is too long, the middle part will bulge. If it is directly pressed and flattened, wrinkles or even overlaps will occur, affecting the flattening quality of the optical film. Utility Model Content
