Description
The application is aimed at the patent application number: 202110863325.2, filing date: 2021-07-29, patent name: a method and a device for producing a zipper pull of a sports wear.
Technical Field
The invention relates to the field of relevant accessories of zippers, in particular to a pull-tab production device of a sports wear zipper.
Background
The pull tab of the zipper is typically formed from a sheet of metal having an aperture in which the slider is mounted. These metal sheets tend to be too small to allow the zipper to slide easily; therefore, many manufacturers attach ropes with larger handles at the tail ends of the existing zipper handles, such as the structure shown in Chinese patent CN2415646Y, and the rope type zipper handle consists of a pull rope and a handle body, wherein the handle body is a bicolor flat body, the middle part of the handle body is concave, raised strips are arranged at the upper part and the lower part of the concave part, and the pull rope is fixed at the upper part of the handle body. Which shows the basic structure of existing pull tabs with pull cords.
As shown in CN 110384314A, a pull tab for a slide fastener includes: a coupling body capable of coupling with a slider, and a tab body integrally attached to the coupling body, the coupling body including: an exposed portion exposed from the tab body, and an embedded portion embedded in the tab body, the tab body including: a first resin forming portion including at least one or more annular end portions having an opening and capable of surrounding an end portion of the embedded portion adjacent to the exposed portion; and a second forming portion made of resin, which is formed in the first forming portion with the embedded portion disposed therebetween, wherein the first forming portion and the second forming portion are integrated (formed as a single body).
In the present invention, when the tab body is integrally attached to the coupling body, first, the end of the embedded portion adjacent to the exposed portion in the coupling body is surrounded by the annular end of the first formed portion formed in advance. Then, the second forming portion is formed by injection molding a resin into such first forming portion with the embedded portion disposed therebetween. Thus, the tab body including the first and second forming portions into which the embedded portion of the connecting body is embedded is formed, and the tab is completed. In injection molding of the second forming portion, the annular end portion is disposed at an end portion of a cavity of a molding die of the second forming portion, that is, an end portion of a cavity of the connecting body adjacent to the exposed portion, and an end portion of the embedded portion of the connecting body adjacent to the exposed portion is surrounded by the annular end portion at the end portion of the cavity. The opening of the annular end portion is set to a size such that the annular end portion surrounds an end portion of the embedded portion of the connecting body adjacent to the exposed portion with as little clearance as possible. In this state, the second forming portion is formed by injecting the molten resin into the cavity of the forming die, and the first forming portion and the second forming portion are integrated with the embedded portion disposed therebetween to form the tab body, and the annular end portion remains as an end portion of the tab body adjacent to the exposed portion of the coupling body.
Which shows a way of forming a pull tab with a resin structure.
However, the conventional pull tab, particularly the pull tab of a slide fastener applied to sportswear, has the following problems:
1. the pull-tab structure made of resin is excessively inconsistent in connection between the pull-cord and the pull-tab due to production limitation, so that the positions of the two ends of the pull-cord on the pull-tab are not uniform, and the attractive appearance of the product is affected;
2. the existing production process has poor quality, and the condition of separation between the pull rope and the pull tab is easy to occur;
