A pull-on slider threading machine and a slider threading method

Abstract

The invention discloses a pull-on type slider threading machine and a slider threading method. The pull-on type slider threading machine includes a machine base, a feeding assembly arranged on the machine base, a space sensing assembly, a block positioning assembly, a front entrainment assembly, and a threading assembly. The slider assembly, the rear entrainment assembly, the drag assembly, the slider assembly includes the slider die mechanism and the driving mechanism for driving the slider die mechanism, the slider die mechanism includes the slider die, the limit cylinder and the limit block, the limit cylinder The piston rod is connected with the limit block, and the limit cylinder drives the limit block to conflict with the slider die. The beneficial effects obtained by the present invention: the driving mechanism can drive the slider die mechanism to move along the conveying direction parallel to the zipper tape, which facilitates the slider to be worn on the zipper, avoids damage to the zipper, and improves the quality of the zipper. The opening of the headform ensures that the slider can be worn normally, and has wide applicability. The square positioning component improves the positioning accuracy of the zipper tape, improves the uniformity of the zipper product, and is conducive to ensuring the reliability of the slider-putting process.

Description

technical field [0001] The invention relates to the technical field of zipper processing, in particular to a pull-on type slider threading machine and a slider threading method. Background technique [0002] The process of zipper processing includes the process of threading the slider. In the prior art, the slider is loaded into the slider mold, and then the slider is worn on the zipper. Due to the lack of driving the slider mold is conveyed parallel to the zipper belt. The drive mechanism that moves in the same direction leads to the steps of threading the slider in the prior art: firstly divide the zipper tape, embed the slider into the zipper tape at the parting place, drag the zipper tape through the dragging assembly, and pass the bandage Tighten the zipper tape to force the zipper into the slider, and drag the zipper tape to make the slider wear on the zipper. This way of threading the slider will force the zipper into the slider. It will cause some damage to the zipp...

[0002] The process of zipper processing includes the process of threading the slider. In the prior art, the slider is loaded into the slider mold, and then the slider is worn on the zipper. Due to the lack of driving the slider mold is conveyed parallel to the zipper belt. The drive mechanism that moves in the same direction leads to the steps of threading the slider in the prior art: firstly divide the zipper tape, embed the slider into the zipper tape at the parting place, drag the zipper tape through the dragging assembly, and pass the bandage Tighten the zipper tape to force the zipper into the slider, and drag the zipper tape to make the slider wear on the zipper. This way of threading the slider will force the zipper into the slider. It will cause some damage to the zipper and reduce the quality of the zipper; and it is necessary to pull the slider in the process of wearing the slider to open the locking piece inside the slider. Since different sizes of sliders require different forces to open the slider, However, the existing equipment often only uses the same cylinder to pull the tab, so the cylinder needs to meet the requirements for pulling the tab of the largest slider. The opening of the slider mold caused the equipment to fail and the slider could not be worn; moreover, there was a lack of positioning components for the zipper tape during the process of threading the slider, resulting in different positions for the slider to be worn on each zipper. lack of unity
