Film material constant-speed folding device

The utility model discloses a film material constant-speed folding device, which relates to the field of film material folding and comprises a conveying mechanism and a folding mechanism, and the conveying mechanism comprises a side plate, a first bearing seat, a lower traction roller, a chute bearing seat, an upper traction roller, a turbine motor and a pressure cylinder. The turbine motor drives the lower traction roller to rotate, the upper traction roller presses a film material on the lower traction roller, the lower traction roller pushes the film material to enter the folding mechanism, then the lower traction roller drives the large synchronous wheel to rotate, the large synchronous wheel drives the small synchronous wheel to rotate through the belt, and therefore the two sets of swing arm rollers are driven to rotate. And the film material passes through the space between the two groups of swing arm rollers after passing through the lower roller, so that the two groups of swing arm rollers are driven
