Description

Technical Field

[0001] This utility model belongs to the field of metal zipper processing technology, specifically a positioning structure for metal zipper processing. Background Technology

[0002] Metal zippers are a type of zipper. They mainly consist of a fabric tape, metal teeth, a zipper pull, and locking mechanisms. The fabric tape provides basic connection and support; the teeth are the core interlocking components that enable opening and closing. Compared to nylon and resin zippers, metal zippers are more robust and are often used on jeans, jackets, and backpacks.

[0003] In the manufacturing process of metal zippers, metal teeth are installed and pressed onto the fabric tape, and then the fabric tape is connected to the object, so that the object can be closed with the help of the metal teeth and the zipper pull.

[0004] Metal zipper teeth and fabric tape are generally quite long. When sewing the fabric tape to an object, it is necessary to push the object and the zipper tape under the sewing needle of the sewing machine so that the sewing machine can sew the fabric tape and the object together. However, the fabric tape cannot be positioned during movement, which will cause the fabric tape to deviate during the pushing process, resulting in deviation between the fabric tape and the sewn object. Therefore, a positioning structure for metal zipper processing is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a positioning structure for metal zipper processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a positioning structure for metal zipper processing, including a mounting plate, a fixing frame fixedly mounted on the top of the mounting plate, a positioning component mounted on the left side of the fixing frame, and a fixing component mounted on the top of the mounting plate.

[0007] The positioning component includes a slide groove on the left side of the fixing frame and an insertion interface on the left side of the mounting plate. A connecting block one is slidably installed inside the slide groove. A first clamping plate is fixedly installed on the left side of the connecting block one. A connecting block two is slidably installed inside the insertion interface. A second clamping plate is fixedly installed on the left side of the connecting block two. A rotating screw is threadedly connected inside the first clamping plate. A compression spring is installed on the outer surface of the rotating screw. The top end of the compression spring is installed at the bottom of the first clamping plate, and the bottom end of the compression spring is installed at the top of the second clamping plate.

[0008] Preferably, the top of the fixing frame is provided with a threaded hole, the top of the connecting block is provided with a slide rail, the top of the mounting plate is provided with a slide rail, the inside of the threaded hole is threaded with a threaded post, and the outer surface of the threaded post is threaded with a limit sleeve.

[0009] Furthermore, when the limiting sleeve rotates and fits against the bottom of the connecting block one on the threaded column, the first clamping plate is fixed on the outer surface of the rotating screw, which can initially limit and fix the first clamping plate and the connecting block one, and prevent the connecting block one from shifting.

[0010] Preferably, the bottom of the threaded column passes through slide rail one and slide rail two and extends to the top of connecting block two, and the limiting sleeve is installed at the bottom of connecting block one.

[0011] Preferably, a connecting plate is fixedly installed on the top of the first clamping plate, a plug-in plate is fixedly installed on the top of the connecting plate, and a hole is opened on the top of the second clamping plate, with the top of the plug-in plate inserted into the hole.

[0012] Furthermore, when the first clamping plate moves up and down along the outer surface of the rotating screw, the connecting plate and the plug plate limit and fix the upper and lower positions of the first clamping plate to prevent the first clamping plate from shaking.

[0013] Preferably, the fixing component includes a fixing block fixedly installed on the front of the mounting plate, the top of the fixing block having a threaded opening, and a fastening bolt being threaded into the threaded opening.

[0014] Preferably, there are two fixing blocks, which are symmetrically distributed on the front and back of the mounting plate, respectively.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model, by rotating the lead screw, allows the first clamping plate to move up and down along the lead screw, and the first clamping plate can drive the connecting block on the right side to move up and down together inside the slide groove. The distance between the first clamping plate and the second clamping plate can be adjusted so that the distance between the first clamping plate and the second clamping plate is adapted to the thickness of the object and the zipper tape after they are stacked. The teeth on the zipper tape are placed inside the first clamping plate and the second clamping plate and made to fit against the side wall, so that the teeth are conveyed along the side wall of the first clamping plate and the second clamping plate, thereby achieving the effect of positioning and conveying the zipper tape and the object forward under the sewing needle for sewing.

[0017] 2. In this utility model, by loosening the threaded post, the first clamping plate and the second clamping plate are pulled to a suitable position, and then the first connecting block and the second connecting block move together. The threaded post will move inside the first sliding track and the second sliding track. Then, the threaded post is tightened, and the bottom of the threaded post will abut against the top of the second connecting block, fixing the position of the second connecting block in the insertion interface. The position of the first clamping plate and the second clamping plate after movement is fixed, achieving the effect of adjusting the position of the first clamping plate and the second clamping plate left and right. This facilitates the placement of zipper tapes of different sizes, so that the zipper tape and the object are sewn together under the sewing needle. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 As shown, the positioning structure for metal zipper processing includes a mounting plate 1, a fixing bracket 11 fixedly mounted on the top of the mounting plate 1, a positioning component 2 mounted on the left side of the fixing bracket 11, and a fixing component 3 mounted on the top of the mounting plate 1.

[0028] The positioning component 2 includes a slide groove 201 on the left side of the fixed frame 11 and an insertion interface 202 on the left side of the mounting plate 1. A connecting block 1 203 is slidably installed inside the slide groove 201. A first clamping plate 204 is fixedly installed on the left side of the connecting block 1 203. A connecting block 205 is slidably installed inside the insertion interface 202. A second clamping plate 206 is fixedly installed on the left side of the connecting block 205. A rotating screw 207 is threadedly connected inside the first clamping plate 204. A compression spring 208 is installed on the outer surface of the rotating screw 207. The top end of the compression spring 208 is installed at the bottom of the first clamping plate 204, and the bottom end of the compression spring 208 is installed at the top of the second clamping plate 206.

[0029] A connecting plate 5 is fixedly installed on the top of the first clamping plate 204, and a plug-in plate 51 is fixedly installed on the top of the connecting plate 5. A hole is opened on the top of the second clamping plate 206, and the top of the plug-in plate 51 is inserted into the hole.

[0030] Through the above technical solution, a fixing bracket 11 is fixedly installed on the top left side of the mounting plate 1. A sliding groove 201 is opened on the left side of the fixing bracket 11. The connecting block 1 203 can slide up and down inside the sliding groove 201. The first clamping plate 204 is fixedly installed on the left side of the connecting block 1 203. The connecting block 205 is inserted into the insertion interface 202 opened on the left side of the mounting plate 1. The second clamping plate 206 is fixedly installed on the left side of the connecting block 205. The first clamping plate 204 and the second clamping plate 206 are both L-shaped and symmetrically distributed. The bottom of the rotating screw 207 passes through the first clamping plate 204 and extends into the interior of the second clamping plate 206. The compression spring 208 is installed between the first clamping plate 204 and the second clamping plate 206. When sewing the zipper tape to the object, the rotating screw 207 is rotated. 07 allows the first clamping plate 204 to move up and down along the rotating screw 207. The compression spring 208 makes the first clamping plate 204 more stable when moving downward. The first clamping plate 204 can also drive the connecting block 203 on the right side to move up and down inside the slide groove 201. The distance between the first clamping plate 204 and the second clamping plate 206 is adjusted so that the distance between the first clamping plate 204 and the second clamping plate 206 is adapted to the thickness of the object and the zipper tape after being stacked. The teeth on the zipper tape are placed inside the first clamping plate 204 and the second clamping plate 206 and are made to fit against the side walls of the first clamping plate 204 and the second clamping plate 206. The teeth are then conveyed along the side walls of the first clamping plate 204 and the second clamping plate 206, achieving the effect of positioning and forward conveying the zipper tape.

[0031] It should be noted that the connecting plate 5 is installed between the first clamping plate 204 and the second clamping plate 206. The plug-in plate 51 is fixedly connected to the connecting plate 5, and the plug-in plate 51 is inserted into the hole of the first clamping plate 204. When the first clamping plate 204 moves up and down, the plug-in plate 51 and the connecting block 203 can prevent the first clamping plate 204 from shaking. The connecting plate 5 can also block the zipper tape to prevent the zipper tape from contacting the compression spring 208.

[0032] Considering the different sizes of the teeth installed on the fabric belt, it is necessary to adjust the first clamping plate 204 and the second clamping plate 206. As shown in the figure, the top of the fixing frame 11 has a threaded hole, the top of the connecting block 1 203 has a slide 4, the top of the mounting plate 1 has a slide 41, the threaded hole is internally threaded with a threaded post 42, and the outer surface of the threaded post 42 is threaded with a limit sleeve 43.

[0033] The bottom of the threaded column 42 passes through slide 1 4 and slide 2 41 and extends to the top of connecting block 2 205, and the limiting sleeve 43 is installed at the bottom of connecting block 1 203.

[0034] Through the above technical solution, a threaded hole is opened at the top of the fixing frame 11, and the threaded post 42 is threaded into the inside of the threaded hole. The threaded post 42 can be inserted into the inside of slide rail 1 4 and slide rail 2 41. When the first clamping plate 204 and the second clamping plate 206 are adjusted left and right, the threaded post 42 is loosened, and the first clamping plate 204 and the second clamping plate 206 are pulled to the appropriate position. Then, the connecting block 1 203 and the connecting block 2 205 will move together. Tightening the threaded post 42 will cause the bottom of the threaded post 42 to penetrate through slide rail 2 41 and abut against the top of connecting block 2 205, thus connecting block 2 205. 205 is fixed in the position inside the insertion interface 202, and the limiting sleeve 43 rotates on the outer surface of the threaded post 42. The limiting sleeve 43 can abut against the bottom of the connecting block 203, and limit and fix the connecting block 203 to the inside of the slide rail 4. Then, the position of the first clamping plate 204 and the second clamping plate 206 after movement is fixed, so that after the mounting plate 1 is fixed to the sewing machine worktable by means of the fixing component 3, the left and right positions of the first clamping plate 204 and the second clamping plate 206 can be adjusted to place zipper tapes of different sizes, which is convenient for sewing zipper tapes with objects.

[0035] It is important to note that a sewing machine is a device that uses mechanical transmission, a sewing needle to pierce the fabric and pull the thread to achieve sewing, and is used to sew zipper tape to objects.

[0036] Furthermore, considering the issue of how to fix the mounting plate 1 to the top of the sewing machine workbench, a diagram is provided to disclose the specific structure of the fixing component 3. The fixing component 3 includes a fixing block 301 fixedly installed on the front of the mounting plate 1. The top of the fixing block 301 has a threaded opening, and the internal thread of the threaded opening is connected to a fastening bolt 302.

[0037] There are two fixing blocks 301, which are symmetrically distributed on the front and back of the mounting plate 1, respectively.

[0038] Through the above technical solution, fixing blocks 301 are installed on both the front and back of the mounting plate 1, so that the fastening bolts 302 can be threaded into the threaded holes opened on the top of the fixing blocks 301, and the fastening bolts 302 can be installed into the working interior of the sewing machine to achieve the effect of fixing the mounting plate 1.

[0039] In summary, the working principle of this utility model is as follows:

[0040] When sewing and positioning the zipper tape, firstly, tighten the fastening bolt 302 to connect it to the threaded hole at the top of the fixing block 301. Then, the fastening bolt 302 can be installed inside the sewing machine worktable, fixing the mounting plate 1 to the top of the sewing machine worktable. At this time, the first clamping plate 204 and the second clamping plate are located at the sewing needle of the sewing machine. Rotating the rotating screw 207 allows the first clamping plate 204 to move up and down along the rotating screw 207. Compressing the spring 208 makes the downward movement of the first clamping plate 204 more stable, and the first clamping plate 204 can drive the connecting block 203 on the right side. The device moves up and down inside the slide 201 to adjust the distance between the first clamping plate 204 and the second clamping plate 206, so that the distance between the first clamping plate 204 and the second clamping plate 206 is adapted to the thickness of the object and the zipper tape after being stacked. The teeth on the zipper tape are placed inside the first clamping plate 204 and the second clamping plate 206, and the teeth are made to fit against the side walls of the first clamping plate 204 and the second clamping plate 206, so that the teeth are conveyed along the side walls of the first clamping plate 204 and the second clamping plate 206, thereby achieving the effect of positioning and conveying the zipper tape and the object forward under the sewing needle for sewing.

[0041] After the zipper tape is placed inside the first clamping plate 204 and the second clamping plate 206, it is not under the sewing needle. The position of the first clamping plate 204 and the second clamping plate 206 needs to be adjusted. First, loosen the threaded post 42, then pull the first clamping plate 204 and the second clamping plate 206 to the appropriate position. Then, connecting block one 203 and connecting block two 205 will move together, and the threaded post 42 will shift inside the slide rail one 4 and the slide rail two. Then, tighten the threaded post 42. The bottom of the threaded post 42 will abut against the top of connecting block two 205, thus connecting... Block 205 is fixed in position within the insertion interface 202. The limiting sleeve 43 rotates on the outer surface of the threaded post 42 and abuts against the bottom of the connecting block 203, thus limiting and fixing the connecting block 203 to the inside of the slide rail 4. This fixes the position of the first clamping plate 204 and the second clamping plate 206 after they have moved, achieving the effect of adjusting the position of the first clamping plate 204 and the second clamping plate 206 left and right. This facilitates the placement of zipper tapes of different sizes, allowing the zipper tape to be sewn to the object below the sewing needle.
