Detailed Implementation

[0015] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0016] See Figure 1-4This embodiment relates to a zipper head processing positioning fixture, including a positioning turntable body 100 and a limiting strip 110 surrounding it. The positioning turntable body 100 includes a first disc 1 and a second disc 2, as well as a top cover 5 and a connector 6 for detachable installation of the first disc 1 and the second disc 2. The first disc 1 and the second disc 2 are respectively surrounded by a number of sets of spaced first protrusions 10 and second protrusions 20. The second protrusions 20 are located between adjacent first protrusions 10 to form a number of positioning grooves 102. A third disc 3 and a fourth disc 4 are respectively detachably installed on the first disc 1 and the second disc 2. The third disc 3 and the fourth disc 4 are respectively surrounded by a number of sets of third protrusions 30 and fourth protrusions 40 that are respectively sleeved around the first protrusions 10 and the second protrusions 20.

[0017] Specifically in this embodiment, such as Figure 1 The overall structure of this zipper head processing and positioning fixture shown can be combined with [other components] in actual use. Figure 2-4The installation process of the positioning turntable body 100 is shown. Specifically, the second disc 2 can be slidably embedded into the mounting groove 11 provided on the first disc 1. Several sets of second protrusions 20 on the second disc 2 can be slidably engaged in several sets of grooves 12 opened at corresponding positions on the first disc 1, completing the detachable connection process between the first disc 1 and the second disc 2. At the same time, the top cover 5 can be positioned above the second disc 2 and combined with the connector 6 to limit and fix the positioning turntable body 100 structure formed by the first disc 1 and the second disc 2. Furthermore, according to the specifications of the zipper head, a third disc 3 and a fourth disc 4 can be combined and used on the first disc 1 and the second disc 2 respectively. The difference between the structure of the third disc 3 and the first disc 1 is that... The third protrusion 30 is designed to fit around the first protrusion 10. It also features a second mounting groove 31 adapted to the first disc 1, several sets of second grooves 32 for sliding around the first protrusion 10, and third grooves 33 for sliding engagement of the second protrusion 20 and the fourth protrusion 40. This allows for the detachable installation of the third disc 3 under the first disc 1. The fourth disc 4 is detachably connected via a matching frame 41 and a matching annular groove 21 on the third disc 3. The frame 41, formed by several sets of third grooves 33 within several sets of fourth protrusions 40, allows for the detachable installation of the third disc 3 under the first disc 1. The fourth protrusion 40 is adapted to fit around several sets of third protrusions 30 on the third disc body 3. Finally, it is combined with the connecting parts 6, which adopt a threaded rod structure, and are respectively inserted into multiple sets of through holes 101 at corresponding positions on the top plate, the second disc body 2, the first disc body 1, and the third disc body 3. Specifically, it can be used with nuts or connecting parts with threaded holes according to installation requirements. Alternatively, the corresponding through holes 101 on the first disc body 1 and the third disc body 3 can be set with threaded holes, and the connecting parts 6 with the threaded rod structure can be threaded to realize the installation and fixing process of the overall structure of the positioning turntable. In actual use, when the first disc body 1 and the second disc body 2 and the fourth disc body 4 are used in combination, it can be used for zipper heads with larger specifications. When the first disc 1 and its associated third disc 3 and second disc 2 are used in combination, they are suitable for zipper heads with smaller specifications. The lengths of the first protrusion 10, second protrusion 20, third protrusion 30, and fourth protrusion 40 can be customized according to actual usage requirements and the specifications of the zipper head. In conjunction with the working process of commonly used zipper head assembly machines in the prior art, the positioning turntable body 100 can be connected to the driving component and driven to rotate. After a batch of zipper heads are screened and arranged by the vibrating plate and the corresponding slide rails placed at a certain angle on one side of the positioning turntable body 100, they can slide sequentially into the positioning grooves 102 formed by several sets of first protrusions 10 or third protrusions 30 for feeding, in conjunction with the rotation of the positioning turntable body 100.At this time, the second protrusion 20 and the third protrusion 30 in the positioning groove 102 can be inserted to an appropriate length into the corresponding opening at the tail of the zipper head to make their orientation stable and consistent. This will then drive the zipper head in the positioning groove 102 to the side with the limiting strip 110 to limit it and prevent it from sliding out and falling off. Specifically, the limiting strip 110 can be installed and fixed on the zipper head assembly machine by means of the mounting base 111 and the slot 112 provided on it, combined with the bolt connector 6. During the blocking process of the limiting strip 110, the operator can hang the pull tabs on the zipper head in the positioning groove 102 one by one. Then, the pull tabs on the zipper head can be impacted by the impact head located above the positioning turntable body 100 and acted on by the zipper head assembly machine to limit their position. After that, the pull tabs slide out of the positioning groove 102 without being blocked by the limiting strip 110 as the positioning turntable body 100 rotates, and are then collected uniformly. The positioning turntable body 100 in this zipper head processing and positioning fixture has a structural design that, compared to the traditional fixed turntable structure, offers greater flexibility and convenience in assembly and disassembly of the first, second, third, and fourth disc bodies 1, 2, 3, and 4, which are installed and fixed via connector 6 and top cover 5. The disc bodies can be combined and disassembled according to the specifications of the zipper head, providing flexibility and applicability for different zipper head sizes. This facilitates operation and adjustment while further enhancing the versatility of this zipper head processing and positioning fixture, meeting diverse processing and positioning requirements and usage needs.

[0018] The top cover 5 has multiple sets of fifth protrusions 50 arranged around its periphery, corresponding to the positions of the second protrusion 20 or the fourth protrusion 40. The top cover 5 and the second disc 2 are positioned together via a connecting portion. Specifically, during installation, the top cover 5 can be fitted and engaged within the grooves 12 or 33 on the first disc 1 or the third disc 3 using the multiple sets of fifth protrusions 50, thereby further improving the positional stability of the top cover 5 during installation. This also allows for [further integration / combination]. Figure 3 and Figure 4 The connecting part is designed such that the connecting part includes a rib 51 provided on the wall below the top cover 5 and an adapter groove 22 for the rib 51 to be engaged on the corresponding position of the second disc 2. In actual installation, the engagement process of the rib 51 in the groove 22 can ensure the stability of the relative position between the second disc 2 and the first disc 1 and the top cover 5 when the fourth disc 4 is not in use. This improves the connection effect and stability of the overall structure of this zipper head processing and positioning fixture.

[0019] A positioning sleeve 7, detachably connected to the connector 6, is also provided below the first disc 1 or the third disc 3. The positioning sleeve 7 is limited to the first disc 1 or the third disc 3 by a second connecting part thereon. Figure 3 and Figure 4 The positioning sleeve 7 shown is designed so that, in actual use, the threaded hole on the positioning sleeve 7 facilitates a detachable connection process using a connector 6 with an adapted threaded rod structure. Simultaneously, the positioning sleeve 7 has a connecting groove 70 and a set screw 71 rotatably connected to the connecting groove 70 on its side wall. This allows for a detachable connection process with the drive shaft of the drive component used to drive the positioning turntable body 100 on the zipper head assembly machine, further improving the ease of assembling and disassembling this zipper head processing positioning fixture on the drive component. Additionally, the second connecting part includes the positioning sleeve... The top of the 7 has a second rib 72, and the bottom of the first disc 1 and the third disc 3 have corresponding grooves 13 and 34 for the second rib 72 to be fitted and locked. According to actual use requirements, during installation, the positioning sleeve 7 can be locked in the second groove 13 or the third groove 34 at the bottom of the first disc 1 or the third disc 3 through the second rib 72, and thus be connected and fixed to the connector 6. The addition of the second connection part can effectively improve the stability of the relative installation position of this zipper head processing positioning tool on the positioning sleeve 7, and ensure its connection effect and use stability.

[0020] The limiting strip 110 is rotatably provided with several sets of evenly arranged rubber shafts 113, combined with Figure 1 and Figure 5 As shown, when the positioning turntable body 100 rotates under the drive of the driving component, when the head end of the zipper head located in the positioning groove 102 abuts against the rubber shaft 113, the rubber shaft 113 can rotate accordingly along the moving direction of the zipper head. Compared with the traditional limit strip 110 with a sheet-like structure, the arrangement of several sets of rubber shafts 113 on it will not cause the zipper head to jam, and can effectively reduce the unnecessary wear on the surface of the zipper head, improve the functional diversity of this zipper head processing positioning fixture, and ensure the stability of the zipper head quality during the processing positioning process.

[0021] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
