Film conveying mechanism for film laminating machine

The utility model provides a film conveying mechanism for a film laminating machine. The film conveying mechanism comprises two groups of synchronous wheels, two groups of synchronous belts, two groups of clamp strips and two rotary shafts. The two groups of synchronous wheels are connected with each other by the two rotary shafts; each group of synchronous wheels is divided into first-layer synchronous wheels and second-layer synchronous wheels, each group of synchronous belts is divided into a first synchronous belt and a second synchronous belt, the first synchronous belts are linked onto the first-layer synchronous wheels, the second synchronous belts are linked onto the second-layer synchronous wheels, and the first-layer synchronous wheels and the second-layer synchronous wheels are in vertically meshed transmission with one another via gears; the two groups of clamp strips are symmetrically fixed to two ends of the two groups of synchronous belts, each group of clamp strips is divided into a first clamp strip, a second clamp strip, a third clamp strip and a fourth clamp strip, the first clamp strips and the second clamp strips are positioned at meshed positions of the first synchronous belts and the second synchronous belts, and the third clamp strips and the fourth clamp strips are positioned on the outer sides of the first synchronous belts and the second synchronous belts. The film conveying mechanism has the advantages that thin films can be meshed and clamped by the clamp strips via the upper synchronous belts and the lower synchronous belts, power can be transmitted by the synchronous wheels, and accordingly the films can be synchronously conveyed.
