Zipper splicing device

The utility model discloses a zipper splicing device, relates to the field of zipper manufacturing equipment, and solves the problem that manual operation is needed for zipper splicing. Comprising a zipper belt leading-in mechanism, a vacancy sensing mechanism, a tooth combining mechanism, a clamping and inserting mechanism, a zipper belt leading-out mechanism and a control system for controlling all the mechanisms to operate, and after the clamping and inserting mechanism clamps a square block of a zipper belt on one side to a positioning station to be positioned, a plug pin of a zipper belt on the other side is clamped to be inserted into the square block; and the zipper belt leading-out mechanism guides the zipper teeth to penetrate through the splicing channel to splice the zipper. The vacancy sensing mechanism senses vacancies between zipper belts, a square bolt sensing groove in a sensing hook is positioned to a square bolt entering a groove, the clamping and inserting mechanism clamps the zipper belts
