Automatic spring puller feeding device

Abstract

The invention relates to the field of zipper machinery, in particular to an automatic spring puller feeding device which comprises a pushing mechanism, a feeding mechanism, a piece pushing mechanism and a mold mechanism, the pushing mechanism is used for pushing pullers to the feeding mechanism one by one, and the feeding mechanism is used for limiting and erecting the pullers one by one so that the pulling piece state of the pullers can be adjusted and the pullers can be conveyed to the mold mechanism, the piece pushing mechanism is used for adjusting a pull piece of a pull head limited on the feeding mechanism to be in an unlocking state, and the mold mechanism is used for limiting and placing the pull head for subsequent procedures; the mold mechanism is provided with a puller model groove for placing a puller conveyed from the feeding mechanism, the feeding mechanism comprises a movable material receiving port which is correspondingly connected with the output end of the material pushing mechanism, and the piece pushing mechanism comprises a pulling sheet movable push rod which can push a pulling sheet corresponding to the material receiving port. By means of the device, the spring puller can be adjusted to be in an unlocking state, the unlocking state can be kept for conveying, and puller penetrating work can be conducted, so that the problem that an existing automatic puller penetrating machine cannot conduct automatic puller penetrating of the spring puller is solved.

Description

technical field [0001] The invention relates to the field of zipper machinery, in particular to a mechanical device for automatic feeding of spring sliders in the zipper machinery. Background technique [0002] As one of many sliders, the spring slider has the same basic function as the ordinary slider. The difference is that the spring slider has the function of automatically locking the slider on the zipper to prevent it from being easily opened. Therefore, this spring slider When opening and closing the zipper, the slider needs to be unlocked by the slider to pull the slider. Usually, the slider on the slider must be rotated 90 degrees (that is, the slider is perpendicular to the surface of the slider, or tends to Close to 90 degrees, the following will be directly described as 90 degrees) to unlock, to penetrate the zipper, and slide freely on the zipper, such as figure 1 In the locked state, the spring slider in this state cannot be inserted into the zipper, nor can it...

AI Technical Summary

Problems solved by technology

[0003] In the zipper production process, when the spring slider is inserted into the zipper, it must be turned and pulled until it is in the unlocked state before it can be inserted. In the manual zipper threading work, the manual operation is directly received, but the manual operation has low efficiency. However, in the work of mechanical automation zipper threading that can greatly improve efficiency, the pull tabs of some spring sliders can achieve the function of maintaining the unlocked state, that is, the pull tabs can maintain 90 degrees when adjusted to 90 degrees. State, this kind of spring slider that can be maintained needs to be adjusted once in the automatic feeding of the slider to carry out subsequent conveying and threading work, but some spring sliders cannot easily achieve unlocking or even do not maintain unlocking The effect of the state, the pull piece may be easily in or restored to the locked state, and it needs external intervention to adjust to the unlocked state before the subsequent head piercing work can be carried out

[0004] For the above-mentioned function that can keep the unlocked state but there is no adjustment of the unlocked state once in the automatic threading and feeding, there are also some spring sliders that do not maintain the unlocked state well or do not have the function of maintaining the unlocked state, which cannot be more effective and smooth. It is even impossible to perform automatic head-threading work in some existing automatic head-threading machines, which hinders the improvement of the automatic head-threading efficiency of this spring slider, and there has been no better solution in the industry.
