Zipper structure and manufacturing process thereof

Abstract

This invention relates to the field of zipper structure technology, specifically to a zipper structure and its manufacturing process. The structure includes a fabric tape and zipper teeth, equidistantly mounted on the fabric tape. Both the upper and lower surfaces of the zipper teeth have stitching grooves, which are arc-shaped. A strip-shaped vertical plate is fixedly mounted on the bottom surface of the stitching groove, and a fixing cap is fixedly mounted on the upper end of the strip-shaped vertical plate. Through the cooperation of the various components, during zipper production, when conductive thread is inserted into the fabric tape using a sewing device, the fixing cap causes the conductive thread to slide onto both sides of the strip-shaped vertical plate, embedding the fixing cap inside. This secures the conductive thread within the stitching groove, connecting multiple independent zipper teeth into a single unit, increasing the fixing strength of the zipper teeth, extending the service life of the entire zipper, and simultaneously improving the conductivity of the electroplating process, ensuring the production quality of the zipper.

Description

Technical Field

[0001] This invention relates to the field of zipper structure technology, specifically to a zipper structure and its manufacturing process. Background Technology

[0002] Zippers are connectors that use continuously arranged teeth to join or separate items, and are now widely used in clothing, bags, tents, etc. A zipper consists of teeth, a slider, and top and bottom stops (front and back stops) or locking mechanisms. The teeth are the key component, directly determining the zipper's lateral tensile strength. Generally, copper metal is used to make the teeth to extend their lifespan. However, existing copper zipper teeth are directly fixed to the fabric tape using installation equipment, making each tooth an individual unit. Therefore, the strength of each tooth determines the lifespan of the entire zipper. Furthermore, the conductive medium connecting each tooth makes electroplating after production prone to producing unsatisfactory plating results, affecting the zipper's overall quality. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a zipper structure and its manufacturing process, which can effectively solve the problem that in the existing technology, the zipper teeth are all individual units and there is no conductive medium between each group of zipper teeth. Therefore, the electroplating effect of the zipper is not ideal, and the service life of the zipper is also affected by the strength of the individual zipper teeth.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: This invention provides a zipper structure, including a fabric tape, and further comprising: Zipper teeth are equidistantly installed on the fabric tape. Both the upper and lower surfaces of the zipper teeth are provided with stitching grooves, and the stitching grooves are arc-shaped. A strip vertical plate is fixedly installed on the bottom surface of the stitching groove, and a fixing cap is fixedly installed on the upper end of the strip vertical plate.

[0005] Furthermore, it also includes conductive thread for securing the zipper teeth, the conductive thread being located inside the thread groove and sewn inside the fabric tape.

[0006] Furthermore, the fixing cap has an inverted V-shaped structure, and the ends of the fixing cap are arc-shaped, while the two sides of the fixing cap are pointed.

[0007] Furthermore, the conductive suture is made by a conductive wire and a center line, with the conductive wire located inside the center line.

[0008] Furthermore, it also includes a clamping device for fixing the end of the conductive thread, comprising two sets of housings fixedly installed on the surface of the fabric tape, wherein an extrusion plate is rotatably connected inside the housing, and the extrusion plate is elastically connected to the inner wall of the housing through a torsion spring, and a through hole is provided on the surface of the housing.

[0009] A manufacturing process for a zipper structure, the manufacturing process comprising the following steps: S1: First, insert the conductive wire into the center line using the existing winding equipment, and at the same time, install the zipper teeth onto the fabric tape in a symmetrical and staggered manner using the installation equipment; S2: Then, a grooving groove is made on the surface of the installed zipper teeth using a grooving device, and then a conductive thread is inserted into the fabric tape using a sewing device; it is worth noting that during the insertion of the conductive thread, it is necessary to ensure that the conductive thread is inside the grooving groove. S3: When the conductive thread is inside the thread groove, the conductive thread will begin to contact the strip vertical plate with the fixing cap installed at the top. At the same time, because the upper end of the fixing cap is an arc-shaped structure, the conductive thread will be biased to one side of the strip vertical plate. Therefore, as the conductive thread continues to be sewn in, the conductive thread will be subjected to tension and squeeze against the two sides of the fixing cap. As a result, the two sides of the fixing cap will be embedded in the interior of the conductive thread to fix the conductive thread. S4: After the conductive stitching is inserted, the finished product is powered on to begin electroplating the zipper teeth installed on the fabric tape.

[0010] Beneficial effects

[0011] The technical solution provided by this invention has the following advantages compared with known public technologies: This invention, through the cooperation of various parts, ensures that during zipper production, when the conductive thread is inserted into the fabric tape by the sewing equipment, the thread slides between the thread groove and the vertical strip through the fixing cap installed at the upper end of the vertical strip. Simultaneously, the two sides of the fixing cap secure the conductive thread inside the thread groove. Under the tension generated by the sewing equipment, the conductive thread becomes more stable, allowing multiple independent zipper teeth to form a whole, ensuring the service life of the entire zipper, increasing the electroplating effect during electroplating, guaranteeing the production quality of the zipper, and clamping the cut end of the conductive thread to ensure its tightness.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0016] The present invention will be further described below with reference to embodiments.

[0017] Example:

[0018] A zipper structure, see attached diagram. Figure 1 - Appendix Figure 6 The zipper includes a fabric strip 1, which is composed of two sets of identical fabric pieces; it also includes several zipper teeth 2, which are equidistantly installed on the two sets of fabric pieces. The fabric strip 1 is a flexible strip woven from cotton yarn, chemical fiber, or a mixture of chemical fibers, used to support the zipper teeth 2 and other zipper components. It is worth noting that the zipper teeth 2 are made of copper. It is also worth noting that the zipper teeth 2 are not limited to copper; other materials such as nylon, resin, or aluminum can also be used. Combined with appendix Figure 1It also includes a conductive thread 3 for fixing the zipper teeth 2. The conductive thread 3 is inserted into the fabric tape 1 through existing sewing equipment. On the one hand, it can fix several zipper teeth 2, and on the other hand, it can connect multiple individual zipper teeth 2 into a whole, so as to facilitate the subsequent electroplating of the zipper teeth 2. The conductive stitch 3 is made by combining a conductive wire and a center line, with the conductive wire located inside the center line. By using the conductive wire and the center line to form the conductive stitch 3 and placing the conductive wire inside the center line, the conductive wire can be protected, facilitating subsequent electroplating of the zipper teeth 2. It is worth noting that the conductive stitch 3 is conductive as a whole. The conductive stitch 3 is located inside the stitch groove 201 and sewn inside the fabric tape 1. By sewing it inside the fabric tape 1, the symmetrically staggered zipper teeth 2 can be connected into a whole, so that the zipper is no longer limited to the fixing strength of a single zipper tooth 2 during use, extending the service life of the entire zipper and facilitating subsequent electroplating of the zipper teeth 2, ensuring the electroplating effect of the zipper teeth 2.

[0019] Combined with appendix Figure 2 - Appendix Figure 5 Both the upper and lower surfaces of the zipper teeth 2 are provided with stitching grooves 201, and the stitching grooves 201 have an arc-shaped structure. By setting the stitching grooves 201, it is easier to insert the conductive thread 3 into the fabric tape 1 through the sewing equipment. At the same time, it can also make better contact between the zipper teeth 2 and the conductive thread 3, so that the zipper teeth 2 can be better fixed, thereby extending the service life of the entire zipper. A strip-shaped vertical plate 202 is fixedly installed on the bottom surface of the stitching groove 201. By setting the strip-shaped vertical plate 202, the stitching groove 201 can be divided into two parts, so that the conductive thread 3 can be evenly distributed on both sides of the strip-shaped vertical plate 202 when it is inserted into the fabric tape 1. This ensures that the conductive thread 3 is evenly distributed when it is inserted into the fabric tape 1, increasing the aesthetics of the entire zipper. The upper end of the strip vertical plate 202 is fixedly equipped with a fixing cap 203. By setting the fixing cap 203, the conductive stitching 3 on both sides of the strip vertical plate 202 can be fixed, which strengthens the fixing strength of the zipper teeth 2 and also ensures that the conductive stitching 3 will not be lifted or detached from the stitching groove 201 due to the influence of the external environment. It is worth noting that external factors can include sharp objects accidentally coming into contact with the conductive stitching 3 and moving under the action of external force. The fixing cap 203 has an inverted V-shaped structure and the end of the fixing cap 203 has an arc-shaped structure. By setting the end of the fixing cap 203 to an arc-shaped structure, it can... When the conductive thread 3 is inserted into the fabric tape 1, it will first come into contact with the fixing cap 203. Under the action of the arc-shaped upper end of the fixing cap 203, the conductive thread 3 will easily slide into both sides of the strip vertical plate 202. It is worth noting that when one set of conductive threads 3 slides into one side of the strip vertical plate 202, another set of conductive threads 3 will enter the other side of the strip vertical plate 202 under the squeezing action of the fixing cap 203 and the conductive threads 3 already inserted into the fabric tape 1. The two sides of the fixing cap 203 are pointed. By making the two sides of the fixing cap 203 pointed, the conductive thread 3 can be fixed when it enters the seam groove 201.

[0020] Combined with appendix Figure 6 It also includes a clamping member 4 for fixing the end of the conductive thread 3, which is used to fix the end of the conductive thread 3 after sewing to prevent the end of the conductive thread 3 from loosening after cutting; it includes two sets of outer shells 401 fixedly installed on the surface of the fabric tape 1, and a pressing plate 402 is rotatably connected inside the outer shell 401. The pressing plate 402 is elastically connected to the inner wall of the outer shell 401 through a torsion spring 403. By setting the pressing plate 402, the cut conductive thread 3 can be pressed and fixed. At the same time, in conjunction with the torsion spring 403, the reaction force generated by it can act on the pressing plate 402, so that the pressing plate 402 can fix the conductive thread 3 more effectively; a through hole 404 is provided through the surface of the outer shell 401, which facilitates the sewing needle of the sewing equipment to enter the interior of the outer shell 401.

[0021] Specifically, during zipper production, while inserting the conductive wire into the center line, the zipper teeth 2 are fixed to the fabric tape 1 using a fixing device. Then, the fabric tape 1 with the zipper teeth 2 installed is moved to the bottom of the grooving device, and a stitching groove 201 is opened on the surface of the zipper teeth 2. After the stitching groove 201 is opened, the strip vertical plate 202 and the fixing cap 203 are installed on the bottom surface of the stitching groove 201 using a spot welding device. Then, the completed conductive thread 3 is inserted into the fabric tape 1 through a sewing device, ensuring that the conductive thread 3 is inside the thread groove 201. When the conductive thread 3 enters the thread groove 201, it will slide into both sides of the strip vertical plate 202 under the action of the fixing cap 203 and contact the two sides of the fixing cap 203. This allows the two sides of the fixing cap 203 to be embedded inside the conductive thread 3, fixing the conductive thread 3 while connecting multiple individual zipper teeth 2 into a whole, which facilitates the subsequent electroplating of the zipper teeth 2 and ensures the electroplating effect. After the conductive thread 3 is inserted, the sewing needle will carry the conductive thread 3 into the interior of the outer casing 401. The sewing needle will pass through the through hole 404, and the conductive thread 3 will squeeze the compression plate 402, causing it to rotate and drive the torsion spring 403 to deform. This causes the torsion spring 403 to generate a restoring reaction force that acts on the compression plate 402, so that the compression plate 402 clamps the conductive thread 3, ensuring that the end of the conductive thread 3 can be clamped after it is cut, thus ensuring the tightness of the conductive thread 3 sewing.

[0022] A manufacturing process for a zipper structure, comprising the following steps: S1: First, insert the conductive wire into the center wire using the existing winding equipment, and at the same time, install the zipper teeth 2 symmetrically and staggeredly onto the fabric tape 1 using the installation equipment; S2: Then, a seam groove 201 is made on the surface of the installed zipper tooth 2 using a grooving device, and then the conductive thread 3 is inserted into the fabric tape 1 using a sewing device; it is worth noting that during the insertion of the conductive thread 3, it is necessary to ensure that the conductive thread 3 is inside the seam groove 201. S3: When the conductive thread 3 is inside the thread groove 201, the conductive thread 3 will begin to contact the strip vertical plate 202 with the fixing cap 203 installed at the upper end. At the same time, because the upper end of the fixing cap 203 is an arc-shaped structure, the conductive thread 3 will be biased to one side of the strip vertical plate 202. Therefore, as the conductive thread 3 continues to be sewn in, the conductive thread 3 will be subjected to tension and squeeze against the two sides of the fixing cap 203. As a result, the two sides of the fixing cap 203 will be embedded in the interior of the conductive thread 3 to fix the conductive thread 3. S4: After the conductive stitching 3 is inserted, the finished product is powered on and the zipper teeth 2 installed on the fabric tape 1 are electroplated.
