[0023] In one embodiment of the present invention, the first film layer feeding assembly 11 and the second film layer feeding assembly 12 respectively convey the waterproof breathable film and the release film, which are conveyed to the composite molding assembly 20 through a composite transmission roller, and compounded and cut into a shape suitable for the waterproof breathable cap through a mold. At the same time, the subsequent cutting adjustment assembly 30 timely adjusts the tightness of the film layer conveying to avoid breakage due to shrinkage during composite cutting, or transmission dislocation, which affects the uniformity of the finished waterproof breathable film, thereby achieving timely adjustment.
[0024] Specifically, the composite molding assembly 20 includes an upper mold 21; a lower mold 22; an upper pressure cylinder 23 that drives the upper mold 21 to rise and fall, and the upper pressure cylinder 23 is guided by guide pillars 24 on all sides.
