Since the distance between the two upper guide pieces 345 (or the lower guide pieces 346) increases from front to back, and the distance a between the rear end portions of the two upper guide pieces 345 or the lower guide pieces 346 is greater than the distance b between the tail ends of the two opposing glue filling zipper head glue on both sides of the central glue stick, and the distances between the glue tail ends of the glue-injected zipper head at the two sides of the central glue stick are the same, therefore, when the glue-injected zipper head at the front end part of the upper guide plate 345 moves to the rear end part of the upper guide plate 345, the connecting part of the tail ends of the two glue injection zipper heads and the central glue rod is stretched to be in a stretching state, and because the tail ends of the upper guide piece 345 and the lower guide piece 346 are respectively aligned and supported with the upper cutter 341 and the lower cutter 342, when the glue injection zipper heads move forwards between the upper cutter 341 and the lower cutter 342, the connecting part is still in the stretching state, so that the tail end of the rubber tail can not leave burrs when being cut, and the cutting quality of the rubber injection zipper head is ensured.

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 utility model discloses a head cutting device is drawn to injecting glue, the whole injecting glue after the drawing of patterns is earlier drawn the zipper head and is placed on the bracket to the during operation, then draws the zipper head to remove along the central line direction of central gluey stick by the whole injecting glue of manipulator centre gripping, draws the connecting portion that the stick was glued with every injecting glue tail end and center to carry one by one and cut the mechanism, cuts off from gluing the faying face between tail end and the connecting portion by cutting the mechanism at last.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
