The invention relates to a production and processing device of a waterproof zipper. The invention solves the problem that a gap is generated between a right waterproof glue layer and a left waterproofglue layer of the zipper when processing waterproof zippers in the prior art. The invention adds an opposite slant hole and a blowing pipe to a pressing board structure of a sewing machine in the prior art; according to aerodynamic principle, the cloth ribbons pasted with waterproof glue layer are pushed to middle by the constant air blowed out from the additionally equipped blowing pipe, thus ensuring that the gap between the waterproof glue layer cloth ribbons at the right half side and the left half side of the zipper is close after sewing; at the same time, a spotted fence on the back ofan upper pressing board can avoid overlapping sewing caused by excessive squeeze when the cloth ribbons are pushed to the middle by wind blowing. The invention can guarantee the smooth sewing of the waterproof zipper cloth ribbons pasted with waterproof glue layers and compact sewing gap after sewing, thereby resulting in excellent waterproof performance of the product.
