[0023] Refer to Figures 1 to 4As shown in the figure, a double-opening zipper positioning device includes a support 1, a guiding component 2 and a positioning component 3 arranged on the support 1. The guiding component 2 has a guiding channel 20. The positioning component 3 includes an induction cylinder 31, an induction rod 32, an induction steel sheet 33, a first bearing 34, a second bearing 35, a guide rail component 36, a sliding seat 37, a hook needle cylinder 38, a hook needle 39, a hook needle connecting rod 40, a first tension spring 41, a second tension spring 42, a first proximity switch 43, a second proximity switch 44, a third proximity switch 45, a limit seat 46, a front limit block 47 and a limit bolt 48. The first proximity switch 43 is arranged on the guiding channel 20. The middle part of the induction rod 32 is hinged to the support 1 through the first bearing 34. The induction cylinder 31 is arranged on the support 1 and is distributed at one end of the induction rod 32 close to the first proximity switch 43. The second proximity switch 44 is arranged on the support 1 and is distributed on the periphery of the induction cylinder 31. The first tension spring 41 connects the support 1 and one end of the induction rod 32 close to the first proximity switch 43. The induction steel sheet 33 is arranged at one end of the induction rod 32 far from the first proximity switch 43. The second bearing 35 is arranged at the lower end of the induction steel sheet 33. The second bearing 35 is distributed in the guiding channel 20. The guide rail component 36 is arranged on the support 1, and the guiding direction of the guide rail component 36 is the same as that of the guiding channel 20. The sliding seat 37 is arranged on the guide rail component 36. The hook needle cylinder 38 is arranged on the sliding seat 37. The hook needle 39 is connected to the piston rod of the hook needle cylinder 38 through the hook needle connecting rod 40. The limit seat 46 is arranged on the sliding seat 37. The third proximity switch 45 is arranged on the limit seat 46. The limit bolt 48 is arranged on the limit seat 46 and is distributed on the periphery of the third proximity switch 45. The second tension spring 42 connects the support 1 and the sliding seat 37. The front limit block 47 is arranged at the input end of the guide rail component 36.

[0024] Moreover, a vertically penetrating chute 371 is provided on the sliding seat 37. The hook needle connecting rod 40 is distributed in the chute 371 and slides up and down along the chute 371.

[0025] Specifically, the guiding component 2 includes an arc-shaped guide plate 21, a guide plate 22, two zipper limit plates 23 and two limit columns 24. The guide plate 22 is arranged on the support 1. The first proximity switch 43 is arranged on the guide plate 22. The arc-shaped guide plate 21 is arranged at the input end of the guide plate 22. The two zipper limit plates 23 are arranged on the transverse two sides of the guide plate 22. The two limit columns 24 are arranged on the transverse two sides of the guide plate 22 and are distributed between the zipper limit plates 23 and the arc-shaped guide plate 21.

[0026] The working mode of the present utility model is as follows: For this double-open zipper positioning device, the zipper that has passed through the first slider is conveyed along the guiding channel 20 of the guiding component 2. When the first proximity switch 43 detects the slider on the zipper, the induction cylinder 31 acts, pushing one end of the induction rod 32 to move downward, causing the other end of the induction rod 32 to prop up upward, and then driving the induction steel sheet 33 to swing upward. After the slider passes through the induction steel sheet 33, the induction cylinder 31 resets, and the induction rod resets under the action of the first tension spring 41, so that the second bearing 35 on the induction steel sheet 33 abuts against the zipper. The zipper continues to be dragged and conveyed. When the induction steel sheet 33 detects a vacant position on the zipper, that is, when a vacant position appears, the induction rod 32 swings and is sensed by the second proximity switch 44. The crochet cylinder 38 acts to drive the crochet 39 to move downward and hook into the vacant position of the zipper. When the zipper is conveyed, the crochet 39 and the sliding seat 37 are dragged to move along the direction of the guide rail component 36 to a defined position and are detected as in place by the third proximity switch 45, and then the conveying of the zipper stops, with high positioning accuracy.
