[0025] The present application will be further described below with reference to the drawings and specific embodiments:

[0026] As shown in Figure 1 , 2 A double-pull rubber tooth zipper positioning device, comprising a material guide assembly 1 and a transmission mechanism (not shown in the figure), the material guide assembly 1 comprises an upper material guide plate 11 and a lower material guide plate 12, the upper material guide plate 11 and the lower material guide plate 12 are provided with a chain belt feeding channel 10 opposite each other, the transmission mechanism is used to pull the chain belt 21 through the chain belt feeding channel 10, the lower material guide plate 12 is provided with a probe mechanism 3 below, the probe mechanism 3 is used to detect the zipper empty space 22 of the zipper 2;

[0027] The upper material guide plate 11 is provided with an upper die 4 for threading the puller, and the upper part of the upper material guide plate 11 is located between the upper die 4 and the probe mechanism 3 and is provided with a hook needle positioning mechanism 5, which is correspondingly arranged with the chain belt feeding channel 10, and is used to hook the upper stop end 23 of the zipper 2 when triggered, and the hook needle positioning mechanism 5 and the upper material guide plate 11 are respectively provided with a pullback mechanism 6, and the hook needle positioning mechanism 5 is slidably connected with the upper material guide plate 11 through the pullback mechanism 6, and the upper part of the upper die 4 is provided with a position detection sensor 7, which is used to detect the simultaneous arrival of the two hook needles 51 and control the transmission mechanism to stop.

[0028] In this embodiment, the zipper 2 is a zipper material that is not cut off and the two chain belts 21 are in a separated state, and the zipper material is provided with a zipper gap 22 between the upper zipper 2 and the lower zipper 2, and the upper zipper 2 is provided with an upper stop end 23 at one end close to the zipper gap 22, and the lower zipper 2 is provided with a block plug end 24 at one end close to the zipper gap 22.

[0029] When working, the transmission mechanism on the device drives the chain belt feeding channel 10 to move forward, and since there is no zipper tooth on the zipper gap 22, when the zipper gap 22 of the zipper 2 travels to the sensing position of the probe mechanism 3, the probe mechanism 3 triggers and controls the hook needle 51 mechanism to hook the upper stop end 23 of the zipper 2, and then the hook needle 51 mechanism follows the zipper 2 to continue to move forward in a small range under the action of the transmission mechanism, and when the position detection sensor 7 detects that the hook needle 51 mechanism moves to the set position, the transmission mechanism is controlled to stop running, and then the hook needle 51 mechanism is reset under the action of the pullback mechanism 6, at this time the block plug end 24 of the zipper 2 is located at the position of the upper die 4, thereby realizing precise and efficient positioning of the two-chain-belt-separated zipper 2 before threading the puller, and the operation is stable and reliable.

[0030] Further, as shown in Figure 1 、 2 The lower material guide plate 12 is provided with a probe hole 121 at the chain belt feeding channel 10, and the probe hole 121 is arranged below the zipper tooth of the chain belt 21, and the probe mechanism 3 includes a probe 31, a probe tension spring 32 and a probe sensor 33.

[0031] The middle part of the probe 31 is rotatably connected with the lower material guide plate 12, the probe end is located in the probe hole 121, and the other end is provided with a probe sensor 33 and a probe tension spring 32 on both sides, respectively, the two ends of the probe tension spring 32 are connected with the probe 31 and the lower material guide plate 12, respectively, and the probe tension spring 32 is used to pull the probe 31 to make the probe end close to the chain belt feeding channel 10.

[0032] In this embodiment, when the zipper gap 22 of the zipper 2 travels to the probe perforation 121, the probe end of the probe 31 drops into the zipper gap 22 under the pulling force of the probe pulling spring 32, thereby rotating the probe 31, changing the distance between the other end of the probe 31 and the probe sensor 33, and triggering the probe sensor 33. After the probe sensor 33 is triggered, the crochet 51 mechanism is started to control, thereby achieving accurate detection of the zipper gap 22 to control the starting of the crochet 51 mechanism.

[0033] Further, as shown in Figure 1 、 2 , the upper material guide plate 11 is provided with a crochet perforation 111 corresponding to the position of the chain belt feeding channel 10, the crochet perforation 111 is arranged above the chain teeth of the chain belt 21, and the crochet perforation 111 is located between the probe perforation 121 and the upper die 4.

[0034] The crochet 51 mechanism includes a crochet 51 and a crochet driver 52, the crochet 51 is located above the crochet perforation 111, the other end of the crochet 51 is connected with the driving end of the upper crochet driver 52, and the crochet driver 52 is slidingly connected with the upper material guide plate 11 through the back-pulling mechanism 6.

[0035] In this embodiment, when the probe sensor 33 is triggered, the crochet driver 52 is controlled to move the crochet 51 in the direction close to the crochet perforation 111, until the hook end of the crochet 51 is in place, then the crochet 51 hooks the upper stop end 23 of the zipper 2 moving forward, and follows the zipper 2 to move forward in a small range. When the in-place detection sensor 7 detects that the crochet 51 moves to the set position, the transmission mechanism is controlled to stop running, and then the crochet 51 mechanism is reset under the action of the back-pulling mechanism 6, at this time the square plug end of the zipper 2 is located at the gap of the upper die 4; thereby accurately hooking the upper stop end 23 of the zipper 2 in the process of positioning the zipper 2.

[0036] Further, as shown in Figure 1 、 2 , the back-pulling mechanism 6 includes a sliding block 61, a back-pulling spring 62 and a connecting plate 63, the sliding block 61 is slidingly connected with the upper material guide plate 11 through a sliding rail, the connecting plate 63 is connected with the upper material guide plate 11 and located at the front end of the sliding block 61, the two ends of the back-pulling spring 62 are respectively connected with the connecting plate 63 and the sliding block 61, the crochet driver 52 of the crochet 51 mechanism is connected with the sliding block 61, and the crochet 51 of the crochet 51 mechanism is connected with the driving end of the crochet driver 52 after penetrating through the sliding block 61 upward.

[0037] In this embodiment, when the slider 61 and the hook needle 51 follow the small movement of the zipper 2 and trigger the in-place detection sensor 7, the transmission mechanism stops, and under the action of the back-pulling spring 62, the slider 61 pulls the hook needle 51 back to reset, thereby realizing accurate control of the block plug end of the zipper 2 to be located at the empty position of the upper die 4 during the positioning of the zipper 2.

[0038] In addition, in this embodiment, since the two chain strips 21 of the zipper 2 are in a separated state, the transmission mechanism needs to be controlled to stop after the two hook needles 51 are detected to be in place by the in-place detection sensor 7, and through such a structural design, it is ensured that the two chain strips 21 are accurately aligned after being positioned.

[0039] Further, as shown in Figure 1 、 2 In order to improve the accuracy and reliability of the in-place detection of the hook needle 51, the side of the slider 61 close to the in-place detection sensor 7 is provided with a trigger screw 8.

[0040] Further, as shown in Figure 1 、 2 In order to improve the stability of the movement of the slider 61, the back-pulling mechanism 6 further comprises a guide rod 64, one end of the guide rod 64 is connected with the slider 61, and the other end penetrates through the connecting plate 63 and is slidingly connected with the connecting plate 63.
