Description
Technical Field
[0001] This utility model relates to the field of nylon zipper manufacturing technology, and more specifically, to a limiting mechanism for a nylon zipper forming machine. Background Technology
[0002] In the nylon zipper manufacturing industry, the limiting mechanism is a core component that ensures the precision and quality of zipper forming. Its performance directly affects production efficiency and product qualification rate. With the increasing market demand for diversified nylon zipper specifications, the limiting mechanism of traditional nylon zipper forming machines, due to its fixed design, requires disassembling part of the structure and manually adjusting the position of the limiting components when facing the production needs of zippers of different widths and specifications. This is not only cumbersome and time-consuming, but also prone to limit offset due to manual adjustment errors, making it difficult to meet the high-efficiency requirements of continuous production of multi-specification zippers. Existing publication number CN209869355U discloses a screw limiting device for a nylon zipper forming machine, comprising: two forming screws arranged side-by-side inside the nylon zipper forming machine, with their front ends protruding outside the machine; and a screw limiting device disposed on the front side wall of the nylon zipper forming machine and tangent to the threaded section at the front end of the forming screws; the screw limiting device includes a first bearing tangent to the threaded section at the front end of the forming screw and located on the top side of the forming screw; two second bearings tangent to the threaded section at the front end of the forming screw and located on the left and right sides of the forming screw; and a third bearing tangent to the threaded section at the front end of the forming screw and located on the bottom side of the forming screw. Therefore, the forming screws can be limited by the first, second, third, and fourth bearings, preventing them from easily shaking or shifting during rotation, thereby avoiding friction with the inner wall of the nylon zipper forming machine and improving the service life of the forming screws. In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: Traditional nylon zipper forming machines often lack convenient horizontal adjustment functions in their limiting mechanisms. When faced with the production needs of nylon zippers of different widths and specifications, it is often necessary to disassemble part of the structure to adjust the contact position between the turntable and the zipper. This is not only cumbersome and time-consuming, but also prone to unstable limiting and guiding effects of the turntable on the zipper due to manual adjustment errors, making it difficult to adapt to the continuous production of multi-specification zippers. Therefore, a limiting mechanism for a nylon zipper forming machine is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1 As attached Figs. 1 to 4The limiting mechanism of a nylon zipper forming machine shown includes a limiting mechanism 1, a control component 5, a first bearing 2, a screw 3, and a fixing component 4. The limiting mechanism 1 is installed on the side of the fixing component 4. The screw 3 is provided on the side of the limiting mechanism 1 away from the fixing component 4. The first bearing 2 is installed on the outer diameter surface of the screw 3. The limiting mechanism 1 includes a control component 5, a connecting component 6, a rotating component 7, and a second bearing 8. The connecting component 6 is installed on the side of the control component 5. The rotating component 7 is installed on the side of the connecting component 6 away from the control component 5. The second bearing 8 is installed on the outer diameter surface of the rotating component 7.
[0021] Wherein: When the limiting mechanism 1 uses the fixed component 4 as the basic support for the entire structure, the limiting mechanism 1 is installed on its side. The limiting mechanism 1 is the core functional component, which includes a control component 5, a connecting component 6, a rotating component 7 and a second bearing 8. The control component 5 is connected to the connecting component 6, and the connecting component 6 is connected to the rotating component 7. The outer diameter surface of the rotating component 7 achieves stable rotation through the second bearing 8. At the same time, a screw 3 is provided on the side of the limiting mechanism 1 away from the fixed component 4. The outer diameter surface of the screw 3 is equipped with a first bearing 2 to reduce rotational friction. Through the support of the fixed component 4, the coordinated cooperation of the components inside the limiting mechanism 1, and the auxiliary effects of the screw 3 and the first bearing 2, and the rotating component 7 and the second bearing 8, the limiting function of the nylon zipper forming process is achieved.
[0022] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figs. 1 to 4 As shown below, see details: In a preferred embodiment, the control component 5 includes a knob 9, an adjusting threaded rod 10, and a guide rod 11. The adjusting threaded rod 10 is mounted on the side of the knob 9, and the guide rod 11 is provided on the side of the adjusting threaded rod 10 away from the knob 9. The control component 5 uses the knob 9 as the operation input end. When the operator rotates the knob 9, it can directly drive the adjusting threaded rod 10 to rotate. The guide rod 11 on the side of the adjusting threaded rod 10 away from the knob 9 is used to limit the movement direction of the connecting component 6 and prevent it from deviating during rotation.
[0023] In a preferred embodiment, the connecting assembly 6 includes a threaded sleeve 12, a connecting plate 13, and a fixing plate 14. The connecting plate 13 is installed on the side of the threaded sleeve 12, and the fixing plate 14 is installed on the side of the connecting plate 13 away from the threaded sleeve 12. The threaded sleeve 12 engages with the adjusting threaded rod 10 of the control assembly 5 through threads, converting rotational motion into linear motion. The connecting plate 13, as an intermediate connecting member, transmits the power of the threaded sleeve 12 to the fixing plate 14, ultimately driving the rotating assembly 7 to move horizontally.
[0024] In a preferred embodiment, the rotating assembly 7 includes a third bearing 15, a rotating shaft 16, and a turntable 17. The rotating shaft 16 is mounted on the inner diameter surface of the third bearing 15, and the turntable 17 is mounted on the side of the rotating shaft 16. The third bearing 15 is mounted on the outer diameter surface of the rotating shaft 16, which can reduce the frictional resistance when the rotating shaft 16 rotates and ensure its smooth rotation. The rotating shaft 16, as the core component for power transmission, transmits the power of the connecting assembly 6 to the turntable 17. The turntable 17 is in direct contact with the nylon zipper and achieves the limiting and guiding of the zipper through its own rotation.
[0025] In a preferred embodiment, the fixing component 4 includes a fixing slot plate 18, a bearing seat 19, and a connecting block 20. The bearing seat 19 is mounted on the side of the fixing slot plate 18, and the connecting block 20 is provided on the side of the bearing seat 19 away from the fixing slot plate 18. The fixing component 4 uses the fixing slot plate 18 as the basic frame to provide an installation reference for the entire limiting mechanism 1. The bearing seat 19 on its side is used to support rotating components such as the screw 3 to ensure stable rotation. The connecting block 20 is used to connect the fixing component 4 to the limiting mechanism 1 to achieve the fixing of the overall structure.
[0026] In a preferred embodiment, the screw 3 is provided in two sets, the control component 5 and the connecting component 6 are threadedly connected, and the control component 5 and the second bearing 8 are interference fit.
[0027] In a preferred embodiment, the threaded sleeve 12 and the connecting plate 13 are connected by welding, and the connecting plate 13 and the fixing plate 14 are connected by welding. The threaded sleeve 12 is provided in four sets.
[0028] In a preferred embodiment, the third bearing 15 and the rotating shaft 16 are interference fit, the rotating shaft 16 and the turntable 17 are connected by welding, and the turntable 17 is provided with four sets.
[0029] The working process of this utility model is as follows: First, in the production process of nylon zipper, the operation of the limiting mechanism 1 is based on the fixed component 4. The fixed groove plate 18 of the fixed component 4 serves as the frame to provide the installation reference. The bearing seat 19 provides stable support for the screw 3. The connecting block 20 firmly connects the fixed component 4 and the limiting mechanism 1 to ensure that the overall structure does not shake during operation.
[0030] When the zipper limit parameters need to be adjusted, the operator inputs operating force through the knob 9 of the control component 5. The knob 9 rotates and drives the adjusting threaded rod 10 to rotate synchronously. At this time, the guide rod 11 restricts the movement direction of the connecting component 6 to prevent it from deviating. The adjusting threaded rod 10 is engaged with the threaded sleeve 12 of the connecting component 6 through the thread, converting the rotational motion into linear motion. Since the threaded sleeve 12 and the connecting plate 13, and the connecting plate 13 and the fixing plate 14 are all connected by welding, the power is transmitted to the fixing plate 14 in sequence, thereby driving the rotating component 7 to move horizontally.
[0031] When the rotating component 7 is working, the third bearing 15 is installed on the outer diameter surface of the rotating shaft 16 to reduce the rotational friction of the rotating shaft 16 and ensure its smooth rotation. The rotating shaft 16 transmits the power of the connecting component 6 to the turntable 17 connected by welding. The turntable 17 plays a direct limiting and guiding role for the nylon zipper by rotating on its own. The second bearing 8 on the outer diameter surface of the rotating component 7 is interference-fitted with the control component 5, which further ensures the stability of the movement trajectory of the rotating component 7.
[0032] Meanwhile, the two sets of screws 3 on the side of the limiting mechanism 1 away from the fixed component 4, with the assistance of the first bearing 2, work together with the overall structure to achieve adjustment, ensuring that the nylon zipper maintains a stable trajectory during the forming process and improving production quality. The above is the working principle of the limiting mechanism of this nylon zipper forming machine.
