A slider threading method capable of producing ultra-short zippers and an automatic threading machine

Abstract

The invention provides a puller penetrating method capable of producing an ultra-short zipper and an automatic puller penetrating machine. The puller penetrating method includes the steps that when a tape pulling motor is started and puller feeding delay is started, in the puller penetrating process, whether the reaching time of a next cut opening is earlier than the puller feeding delay or not is judged; if the next cut opening is firstly induced, the working process for the ultra-short zipper is implemented, the tape pulling motor stops, puller penetrating stops, a zipper dividing contact pin is moved upwards, a puller die holder is moved downwards, and a puller penetrating work cycle for the next zipper is started; if the puller feeding delay is firstly up, the normal long-zipper working process is carried out, when the puller feeding delay is up, the zipper dividing contact pin is moved upwards, the puller die holder is moved downwards, and the puller penetrating work cycle for the next zipper is started. According to the puller penetrating method and the automatic puller penetrating machine, either the current penetrating zipper is the ultra-short zipper or the normal long zipper is automatically identified through a long-short zipper judgment unit, then different working processes are carried out according to the judgment result, the machine is more automatic, the device use ratio is improved, the production cost is reduced, and the problem that penetrating of a puller of the ultra-short zipper can only be manually carried out is solved.

Description

technical field [0001] The invention relates to a slide fastener production technology, in particular to a slider threading method capable of producing ultra-short slide fasteners and an automatic threading machine. Background technique [0002] At present, zipper production usually produces long chain belts with chain elements first, and then punches and removes certain chain elements at intervals and fixed lengths according to the design length of the finished zipper on the chain belt to form a knife edge without chain elements, and then Then thread the sliders and install the upper and lower stops at these knife edges, and finally cut the zipper tape and divide it into finished zippers. Among them, the chain belt threading slider is completed on the automatic head threading machine. The automatic head threading machine includes a frame, and a pull belt mechanism, a feeding mechanism, a chain splitting mechanism and a control system arranged on the frame. Used to separat...

Problems solved by technology

[0003] In view of the above-mentioned problems existing in the prior art, the technical problem to be solved by the present invention is to provide a method for threading a slider that can produce ultra-short zippers and an automatic threading machine, which can simultaneously produce a head threading machine that produces a normal long zipper. Solve the difficult problem that the ultra-short zipper cannot be produced fully automatically, and effectively reduce the labor cost of the product and the labor intensity of the operator
