The two ends of the supporting plate 82 are open to facilitate the unloading of the zipper.

[0057] The working process of the full-automatic luggage zipper double-puller three-in-one machine is as follows:

[0058] The whole chain belt passes through the belt feeding slide 33 to the lower side of the belt separating cutter 32. Meanwhile, the vibrating feeding screen 41 of the first upper puller device 4 and the second upper puller device 5 works to adjust the posture of the puller and then sequentially sends the puller to the entrance of the puller feeding slide 42. The puller moves through the puller feeding slide 42 to the exit of the puller feeding slide 42, and then is taken away one by one by the puller feeding swing arm 43. The puller feeding swing arm 43 rotates to adjust the horizontal posture of the puller. After the puller is respectively supplemented and placed into the first puller locking block 622 and the second puller locking block 623, the first puller locking block 622 and the second puller locking block 623 move towards the guide block 621 until the first puller fixing position and the second puller fixing position are formed. During the movement of the first puller locking block 622 and the second puller locking block 623, a position is left for the puller. The chain belt pulling clamp hand 71 moves to one side of the belt separating device 3 under the drive of the linear actuator 72. The clamping fingers on the left clamp hand 711 and the right clamp hand 712 open and then respectively clamp the two chain belts of the zipper. The chain belt pulling clamp hand 71 moves back. The left and right chain belts are opened after passing through the first puller. Then, the left and right chain belts enter the two chain belt slides 6212 in the guide block 621 and then pass through the second puller. The two pullers are symmetrically placed along the center line of the guide block 621. The two chain belts are combined together by the second puller. When the chain belt pulling clamp hand 71 moves a distance, the belt pressing block 31 moves downward to press the movable end of the chain belt. The chain belt is cut by the belt separating cutter 32. At this time, the chain belt pulling clamp hand 71 pulls away the zipper formed by the chain belt after passing through the puller. The left clamp hand 711 and the right clamp hand 712 open to place the zipper on the lower zipper device 8. The above process is repeated to continuously complete the double-puller chain belt threading action. When only one puller needs to be threaded, only one puller is provided by the first upper puller device 4 and the second upper puller device 5 to the double-puller belt threading device 6 according to the threading direction, and the other actions remain unchanged.
