Referring to fig. 13, a feed opening 351 is disposed below the cutting mechanism 340, and a material stop plate 352 is disposed behind the cutting mechanism 340 to stop the cut-off glue injection material pulling head from falling into the feed opening 351.

The glue injection zipper head cutting device provided by the invention has the advantages that during work, the whole glue injection zipper head after demolding is placed on the bracket, then the whole glue injection zipper head is clamped by the manipulator to move along the central line direction of the central glue rod, the tail end of the glue tail of each glue injection zipper head and the connecting part of the central glue rod are conveyed into the cutting mechanism one by one, and finally the cutting mechanism cuts off the glue tail end and the connecting part from the combined surface.

The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
