Technical Field
The existing zipper pull-up device comprises the steps that firstly, a pull-up notch is formed in a zipper belt, then, a pull-up die conveys the zipper head to the notch, then, the zipper belt moves forwards to enable a zipper belt without zipper teeth to enter the zipper head until the zipper head abuts against the end parts of the zipper teeth, then, a split pin is used for punching down, the end parts of the zipper teeth are slightly separated, the zipper head can be put in, and then, the zipper belt is conveyed continuously to achieve the work of pulling up the zipper head. As disclosed in chinese patent No. CN 2017111473888, a simple pull-up machine includes a conveying channel, two smoothing blocks are disposed at the rear of the conveying track, two smoothing blocks are disposed at intervals, smoothing through grooves are formed at opposite ends of the two smoothing blocks, smoothing slits are formed at the shortest distance between the upper end and the lower end of the smoothing through grooves, a positioning frame is disposed at the rear of the smoothing through grooves, a positioning platform is disposed at the lower end of the positioning frame, the lower end surface of the positioning platform is parallel to the upper end surface of the smoothing slits, a positioning block is disposed in the positioning frame, a positioning groove is formed at the lower end of the positioning block, limiting blocks are formed at the left side and the right side of the positioning groove in opposite directions, a sliding block is disposed at the positioning groove in a sliding manner, and the limiting blocks are disposed in the sliding groove and are provided with first resetting devices for driving the sliding block to move downwards and enabling the upper end surface of the sliding groove to abut against the upper end surface of the limiting block; a minute hand is arranged in the positioning frame and behind the sliding block, and a minute hand driving device is arranged on the positioning frame; and a pull head die is arranged below the limiting block.
The chain belt moves on the conveying channel, when the initial section of the upper pull head of the chain belt moves to the position below the first induction piece, the first induction piece receives a signal, the second induction piece moves down, the chain belt continues to move, the initial section of the chain belt is known to move to the induction section of the second induction piece to descend, the chain belt is controlled to stop moving, the pull head conveying device is driven to convey the pull head to the chain belt, the pull head moves up to the press-in sliding block, the upper end face of the pull head inlet is parallel to the positioning platform, then the induction section of the second induction piece is separated from the needle to move up, and then the chain belt continues to move to realize the upper pull head work.
The traditional double-needle split-band type upper slider machine has low precision requirement because the second split needle separates the chain belt into larger mouthpieces. However, the pull-up machine in the prior art is provided with the smoothing block, the positioning platform, the limiting block and other limiting structures, so that the pull-up device is required to be high in precision, but in the actual production process, the fact that the chain belt is only slightly tensioned through the traction wheel is found, the chain belt is not tensioned enough in the conveying process, and therefore the success rate of the chain belt slightly deviates to influence the winding is caused in the market.
