[0023] In this double-opening zipper head threading machine, a zipper without a pull head or with only one pull head is sequentially passed through the chain guiding mechanism 2, the die mechanism 6 and the belt pulling mechanism 5, and the belt pulling mechanism 5 pulls the zipper to move. The chain guiding mechanism 2 guides the zipper to prevent the zipper from knotting and flipping. The pull head enters the threading die of the die mechanism 6 through the vibrating feeding mechanism 3 and the feeding mechanism 4. At the same time, the zipper enters the pull head positioning assembly 61 of the die mechanism 6, and the zipper is conveyed along the arc-shaped guide plate 102 and the guide plate conveyor 103. When the first proximity switch 116 detects the pull head on the zipper, the induction cylinder acts to push one end of the induction rod 105 downward, so that the other end of the induction rod 105 props up upward, and then drives the induction steel sheet 106 to swing upward. After the pull head passes through the induction steel sheet 106, the induction cylinder 104 resets, and the induction rod resets under the action of the first tension spring 114, so that the second bearing 108 on the induction steel sheet 106 abuts against the zipper. The zipper continues to be dragged and conveyed. When the induction steel sheet 106 detects a vacant position on the zipper, that is, when a vacant position appears, the induction rod 105 swings and is sensed by the second proximity switch 117. The crochet cylinder 111 acts to drive the crochet 112 to move downward and hook into the vacant position of the zipper. When the zipper is conveyed, the crochet 112 and the sliding seat 110 are dragged to move along the direction of the guide rail assembly 109 to a limited position and are detected by the third proximity switch 118 to be in place, and then the conveying of the zipper is stopped. The positioning accuracy is high. Then, the piercing die 62 acts to pierce the pull head into the zipper at the limited position. It can first pierce the first pull head, then turn the zipper around and pierce the second pull head, and has the functions of threading the closed and open zippers, which can be used for multiple purposes and improves the production efficiency.
