Description

Pull tab assembly machine for zipper pull

technical field

The utility model relates to a zipper slider production equipment, in particular to a slider assembly machine for a zipper slider.

Background technique

As shown in Figure 1, the zipper puller is generally composed of a slider A, an iron hook B, a horse hook C, a cap D, and a pull piece E. Correspondingly, in the zipper pull assembly process, there is a pull piece assembly process. Some automatic zipper puller assembly machines are designed with a corresponding pull tab feeding mechanism for each standard shape of the pull tab so that the standard shape of the pull tab can be assembled. However, for some zipper pullers with small output, if a zipper puller assembly machine is specially designed for them only because of the different shapes of the pull tabs, it will obviously lead to a substantial increase in production costs; in addition, for some pull tabs with non-standard shapes, The traditional zipper puller assembly machine is also unable to realize automatic feeding and automatic assembly of pull tabs. Therefore, in the actual production process, the assembly of zipper sliders with small output or non-standard pull piece shape is often a semi-automatic operation, that is: first use an automatic assembly machine to assemble the slider A, iron hook B, horse hook C and cap. The cover D is fed in sequence and riveted on the end D1 of the cap D to assemble a semi-finished product (the part shown on the left in Figure 1); then manually hang the pull piece E on the pull ring B1 of the iron hook B; Finally, use pliers or a manual punching table to close or narrow the gap B3 of the pull ring B1 of the iron hook B to fix the pull piece E. Since the assembly of the pull tab E is completely manual, the production efficiency is low, and the stability of the product quality is not good, and the product is easily processed and scrapped.
