Description
TECHNICAL FIELD
[0001] The utility model relates to a film flattening device technical field, specifically a film anti-curling flattening device for film production line. BACKGROUND
[0002] In the film processing production line such as trolley battery diaphragm, the film needs to be wound on multiple guide rollers. Among them, the adjacent guide rollers have a certain distance limit. If the span of the two adjacent guide rollers is large, the film is prone to curling and wrinkling. The traditional way is to separately increase the guide roller at the place where the film span is large, but it is often limited by space, resulting in no installation space for the guide roller, and the long span and high processing precision of the guide roller will result in high processing cost.
[0003] Therefore, we designed and developed the film anti-curling flattening device. During film production, corresponding fixed rollers and movable rollers are designed on both sides of the film to tighten both ends of the film, thereby effectively preventing the film from curling and wrinkling due to the large distance between the guide rollers.
