Description

Technical Field

[0001] This application belongs to the field of garment processing technology, specifically relating to a zipper sewing template and an automatic zipper feeding machine. Background Technology

[0002] Zippers are connectors that use continuously arranged teeth to bring items together or separate them. They are widely used in the clothing industry, especially in the connection of front plackets and the closure of trouser pockets.

[0003] Currently, in garment manufacturing, the zipper is first folded onto the edge of the placket, and then sewn together with the placket using a sewing machine. However, during the sewing process, because the sewing machine's pressing mechanism only presses near the needle, as the placket and zipper move relative to the pressing mechanism, the mechanism squeezes and pulls them, causing deformation. This prevents the zipper from being evenly pressed onto the placket fabric strip, affecting the sewing quality. Furthermore, employees need to constantly press the zipper during the sewing process, which is time-consuming and labor-intensive, increasing their workload and impacting production efficiency. Utility Model Content

[0004] This application provides a zipper sewing template and an automatic zipper feeding machine, aiming to solve the technical problem in the prior art where the zipper is easily misaligned relative to the fabric when sewing zippers and fabric, which affects sewing quality and efficiency.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A zipper sewing template is provided, comprising:

[0007] The base plate has a long, narrow first sewing opening along the first path;

[0008] A partition is rotatably connected to the base plate on one side. The partition has a second sewing opening corresponding to the first sewing opening. The partition and the base plate are fitted together to clamp and fix the fabric.

[0009] A pressure plate, rotatably connected to the partition on one side, has a clearance opening to avoid sewing needles; the pressure plate and the partition are fitted together vertically to clamp and secure the zipper tape; and

[0010] A connecting component, disposed on the base plate, is used to connect and fix the partition and the pressure plate;

[0011] The base plate, the partition plate, and the pressure plate are in a sewn state where they are sequentially attached from bottom to top. In the sewn state, the first sewn opening, the second sewn opening, and the clearance opening are connected vertically.

[0012] In conjunction with the first aspect, in one possible implementation, the pressure plate is further provided with an avoidance channel, which is spaced apart from the avoidance opening along a second path, the second path being perpendicular to the first path, and the avoidance channel is used to allow the chain portion of the zipper to extend upwards out of the pressure plate.

[0013] In conjunction with the first aspect, in one possible implementation, the connecting component includes a snap-fit ​​protrusion and a snap-fit ​​groove. The snap-fit ​​protrusion is disposed on the pressure plate, and the partition plate has a snap-fit ​​interface corresponding to the snap-fit ​​protrusion. The snap-fit ​​groove is disposed on the base plate. In the sewing state, the snap-fit ​​protrusion passes downward through the snap-fit ​​interface and engages with the snap-fit ​​groove.

[0014] In conjunction with the first aspect, in one possible implementation, a side hinge is provided between the pressure plate and the partition, with both ends of the side hinge connected to the partition and the pressure plate respectively, so that the pressure plate swings about the central axis of the side hinge.

[0015] In conjunction with the first aspect, in one possible implementation, the avoidance channel extends along the first path, and the length of the avoidance channel is equal to the length of the zipper, so as to limit the displacement of the zipper on the first path.

[0016] In conjunction with the first aspect, in one possible implementation, the base plate is provided with two limiting plates, one end of which is rotatably connected to the upper surface of the base plate, and the axis of rotation is perpendicular to the first path; the two limiting plates are respectively located at both ends of the first sewing opening, and the two limiting plates are respectively attached to the upper and lower parts of the base plate to clamp and fix the fabric to limit the displacement of the fabric on the first path.

[0017] In conjunction with the first aspect, in one possible implementation, the base plate, the partition plate, and the pressure plate are all transparent plates.

[0018] In conjunction with the first aspect, in one possible implementation, the base plate is provided with a fabric outline.

[0019] Compared with existing technologies, the zipper sewing template provided in this application features a base plate, partitions, and pressure plates to secure the fabric and zipper. During sewing, the pressure plates and partitions are opened, the fabric is placed on top of the base plate, the partitions are flipped to clamp the fabric between the partitions and the base plate, and then the pressure plates are flipped again to clamp the zipper with the partitions. Connecting components are used to secure the partitions and pressure plates, increasing clamping strength. The template is then moved onto a sewing machine, which automatically sews along the first sewing hole, joining the zipper and fabric together. The entire process utilizes partitions and pressure plates to secure the fabric and zipper respectively, and connecting components to secure the partitions, pressure plates, and base plate. The pressure plates always press down on the zipper, eliminating the need for manual pressing, significantly reducing employee involvement, lowering labor intensity, and increasing sewing efficiency. The pressure plates and partitions secure the fabric and zipper vertically, providing a large clamping area, preventing the zipper or fabric from shifting or deforming during use, thus improving sewing quality.

[0020] Secondly, an automatic zipper feeding machine is provided, comprising:

[0021] The sewing machine body has a processing platform;

[0022] The zipper sewing template, as described in any of the above possible implementations, is disposed on the processing platform, and the zipper sewing template is movable along a first path and also along a second path; and

[0023] A clamping element is installed on the processing platform. The clamping element has a clamping end that extends above the zipper sewing template. The bottom of the clamping end is in vertical contact with the top of the zipper sewing template to restrict the displacement of the zipper sewing template in the vertical direction.

[0024] In conjunction with the second aspect, in one possible implementation, the clamping component includes a clamping body and a clamping arm disposed on one side of the clamping body, the bottom surface of the clamping arm is provided with a bonding plate, the bonding plate forms the clamping end, and the clamping body is detachably disposed on the processing platform.

[0025] The automatic zipper feeding machine provided in this application, compared with the prior art, is equipped with a base plate, partition plate, and pressure plate to fix the fabric and zipper. During sewing, the pressure plate and partition plate are opened, the fabric is placed on top of the base plate, the partition plate is flipped so that it clamps the fabric with the base plate, and then the pressure plate is flipped so that it and the partition plate cooperate to clamp the zipper. A connecting assembly is used to fix the partition plate and pressure plate, increasing the clamping strength. The entire template is then moved onto the sewing machine, which automatically sews along the first sewing hole, stitching the zipper and fabric together. Throughout the process, the partition plate and pressure plate fix the fabric and zipper respectively, and the connecting assembly fixes the partition plate, pressure plate, and base plate. The pressure plate always presses downwards to tighten the zipper. This system eliminates the need for employees to manually press the zipper constantly, significantly reducing employee involvement, lowering labor intensity, and increasing sewing efficiency. The pressure plate and divider secure the fabric and zipper vertically, providing a large clamping area. This prevents the zipper or fabric from shifting or deforming during use, improving sewing quality. The zipper sewing template moves automatically on the sewing machine body; employees only need to flip the divider and pressure plate to clamp and secure the zipper and fabric. The connecting components fix the pressure plate and divider during sewing, providing large-area fixation for both the zipper and fabric. This prevents the zipper from twisting or deforming during sewing, further improving sewing quality. Attached Figure Description

Additionally, "multiple" and "several" mean two or more, unless otherwise explicitly specified.

[0046] Please refer to the following: Figures 1 to 5 The zipper sewing template provided in this application is described below. A zipper sewing template includes a base plate 1, a partition plate 2, a pressure plate 3, and a connecting component 4; the base plate 1 has a long strip-shaped first sewing opening 11 along a first path; one side of the partition plate 2 is rotatably connected to the base plate 1, and the partition plate 2 has a second sewing opening 21 corresponding to the first sewing opening 11, the partition plate 2 and the base plate 1 are fitted together vertically to clamp and fix the fabric; one side of the pressure plate 3 is rotatably connected to the partition plate 2, and the pressure plate 3 has a relief opening 31 to avoid the sewing needle, the pressure plate 3 and the partition plate 2 are fitted together vertically to clamp and fix the zipper tape; the connecting component 4 is disposed on the base plate 1 and is used to connect and fix the partition plate 2 and the pressure plate 3; the base plate 1, the partition plate 2, and the pressure plate 3 are in a sewing state where they are sequentially fitted from bottom to top, and in the sewing state, the first sewing opening 11, the second sewing opening 21, and the relief opening 31 are connected vertically.

[0047] It should be noted that the base plate 1, partition plate 2, and pressure plate 3 are all rectangular plates, which are easy to manufacture. The sides of the rectangular plates are parallel to each other. When installing partition plate 2 and pressure plate 3, partition plate 2 can be connected to base plate 1 and pressure plate 3 along the side of base plate 1, so that the sides of base plate 1, partition plate 2, and pressure plate 3 are parallel to each other after installation, which is convenient to manufacture.

[0048] It should be noted that the rotation axis of partition 2 and bottom plate 1 is parallel to the first path; the rotation axis of pressure plate 3 and partition 2 is parallel to the first path.

[0049] It should be noted that, Figure 5 The solid arrows in the diagram represent the first path, and the dashed arrows represent the second path.

[0050] It should be noted that a zipper consists of a chain and two strips of fabric. The two sides of the chain are connected to the strips of fabric. The sewing of the zipper and the fabric refers to sewing one side of the strip of fabric to the other side of the fabric.

[0051] It should be noted that the first sewing opening 11 and the second sewing opening 21 have the same dimensions in the vertical direction. The width of the clearance opening 31 is greater than the width of the second sewing opening 21. After the zipper strip and fabric are sewn together, the employee can directly open the pressure plate 3, take out the zipper, and the fabric will be pulled out from the second sewing opening 21 along with the zipper.

[0052] It should be noted that after the fabric is placed on the base plate 1, the area to be sewn will be aligned with the first sewing opening 11. The partition 2 is flipped over, and the partition 2 and the base plate 1 are fitted together to fix the fabric. A zipper is placed on top of the partition 2 so that the zipper strip covers the second sewing opening 21. Finally, the pressure plate 3 is covered. When sewing, the sewing needle will sew along the first path inside the first sewing opening 11, sewing the fabric on the first sewing opening 11 and the fabric strip on the second sewing opening 21 together, thus achieving the operation of sewing the zipper and the fabric together.

[0053] The zipper sewing template provided in this embodiment, compared with the prior art, is equipped with a base plate 1, a partition plate 2, and a pressure plate 3 to fix the fabric and the zipper. When sewing, the pressure plate 3 and partition plate 2 are opened, the fabric is placed on top of the base plate 1, the partition plate 2 is flipped so that it clamps the fabric with the base plate 1, and then the pressure plate 3 is flipped so that it cooperates with the partition plate 2 to clamp the zipper. The connecting component 4 is used to fix the partition plate 2 and pressure plate 3, increasing the clamping strength. The entire template is then moved onto the sewing machine, and the sewing machine automatically sews along the first sewing hole, thus sewing the zipper... The zipper and fabric are sewn together. The entire process uses partition 2 and pressure plate 3 to fix the fabric and zipper respectively. The connecting component 4 fixes partition 2, pressure plate 3 and base plate 1. Pressure plate 3 always presses the zipper downward, eliminating the need for employees to manually press the zipper all the time. This greatly reduces the degree of employee involvement, reduces labor intensity and increases sewing efficiency. Pressure plate 3 and partition 2 can fix the fabric and zipper in the vertical direction. The clamping area is large, and the zipper or fabric will not deviate during use, thus improving the sewing quality.

[0054] In some embodiments, see Figure 1 and Figure 3The pressure plate 3 is also equipped with a clearance channel 32, which is spaced apart from the clearance opening 31 along a second path perpendicular to the first path. The clearance channel 32 allows the zipper chain to extend upwards from the pressure plate 3. After the pressure plate 3 and the partition 2 are fitted together, the zipper chain extends out from the pressure plate 3 through the clearance channel 32, preventing the pressure plate 3 from being obstructed and affecting its clamping effect on the zipper strip. This ensures that the zipper is evenly pressed onto the strip, improving sewing quality. During sewing, employees do not need to specifically press the zipper chain, reducing their workload.

[0055] In some embodiments, see Figure 1 The connecting component 4 includes a snap-fit ​​protrusion 41 and a snap-fit ​​groove 42. The snap-fit ​​protrusion 41 is located on the pressure plate 3, and the partition 2 has a snap-fit ​​interface 22 corresponding to the snap-fit ​​protrusion 41. The snap-fit ​​groove 42 is located on the base plate 1. In the sewing state, the snap-fit ​​protrusion 41 passes downward through the snap-fit ​​interface 22 and snaps into the snap-fit ​​groove 42. After the pressure plate 3 is placed on the partition 2, the employee presses the snap-fit ​​protrusion 41 to snap into the snap-fit ​​groove 42, thus achieving a fixed connection between the pressure plate 3 and the base plate 1. The snap-fit ​​interface 22 is penetrated by the snap-fit ​​protrusion 41, which limits the snap-fit ​​interface 22 in the horizontal and vertical directions, so that the partition 2 is stably connected to the base plate 1, effectively reducing the shaking and displacement between the components and improving the precision and quality of the entire zipper sewing process. When it is necessary to maintain, clean, or replace the zipper sewing template, the pressure plate 3, partition 2, and base plate 1 can be quickly separated and reassembled, making disassembly convenient.

[0056] As another implementation of the connecting component 4, see [link to documentation]. Figure 3 The connecting component 4 includes an upper magnet 44 and a lower magnet 43. The lower magnet 43 is embedded in the base plate 1, and the upper magnet 44 is correspondingly embedded in the pressure plate 3. When in the sewing state, the lower magnet 43 and the upper magnet 44 are attracted and fixed together, and clamp the partition 2.

[0057] In some embodiments, see Figure 2 A side hinge 5 is provided between the pressure plate 3 and the partition 2. The two ends of the side hinge 5 are connected to the partition 2 and the pressure plate 3 respectively, allowing the pressure plate 3 to swing around the central axis of the side hinge 5. The side hinge 5 connects the pressure plate 3 and the partition 2 together, preventing misalignment when the pressure plate 3 or the partition 2 is flipped, thus reducing the impact on the seam fabrication. This eliminates the need for employees to frequently manually adjust the zipper position or press down forcefully to compensate for any mismatch, reducing the difficulty and workload of manual operation.

[0058] In practice, a side hinge strip 5 is provided between the base plate 1 and the partition plate 2.

[0059] Specifically, the side hinge strip 5 uses adhesive tape, with the pressure plate 3 and partition plate 2 bonded to both sides of the tape respectively. The adhesive tape has high bonding strength, is easy to replace, and has low cost.

[0060] In some embodiments, see Figure 5 The clearance channel 32 extends along the first path, and its length is equal to the length of the zipper, thus limiting the displacement of the zipper on the first path. The clearance channel 32 ensures that the zipper is accurately positioned on the first path, preventing lateral shifting during sewing and improving sewing quality. No additional positioning or fixing of the zipper on the first path is required, reducing manual intervention and lowering the workload for employees.

[0061] In some embodiments, see Figure 1 and Figure 3 The base plate 1 is provided with two limiting plates 12. One end of the limiting plate 12 is rotatably connected to the upper surface of the base plate 1, and the axis of rotation is perpendicular to the first path. The two limiting plates 12 are located at both ends of the first sewing opening 11. The two limiting plates 12 are respectively attached to the base plate 1 from top to bottom, clamping and fixing the fabric to limit the displacement of the fabric on the first path.

[0062] It should be noted that during operation, the two limit plates 12 rotate in opposite directions.

[0063] Two limiting plates 12 are set at both ends of the first sewing opening 11. After the fabric is placed on the base plate 1, the two limiting plates 12 are flipped relative to each other, so that the swing ends of the two limiting plates 12 move closer together. The limiting plates 12 limit the fabric on the first path, preventing zipper sewing deviation caused by fabric movement and improving sewing accuracy. During the sewing process, the base plate 1 and the partition 2 limit the fabric in the vertical direction, and the two limiting plates 12 limit the fabric on the first path. This eliminates the need for employees to frequently adjust the fabric position during sewing, reducing their workload. When it is necessary to change to new fabric, the two limiting plates 12 swing in opposite directions, so that the two swing ends move away from each other, allowing the fabric to be placed without interfering with the fabric placement process.

[0064] In practice, the limiting plate 12 is rotatably connected to the base plate 1 via a side adhesive strip, which is an adhesive tape.

[0065] In some embodiments, the base plate 1, partition 2, and pressure plate 3 are all transparent. The transparent plates allow employees to easily and intuitively observe the relative positions of the fabric and zipper after the pressure plate 3 and partition 2 are attached, which is beneficial for employees to adjust and ensures sewing quality.

[0066] Optionally, the base plate 1, partition plate 2 and pressure plate 3 can all be made of plastic sheets, or acrylic sheets can be used, as long as they have a certain degree of transparency to facilitate employee observation. They will not be listed one by one here.

[0067] In some embodiments, the base plate 1 is provided with a fabric outline. The fabric outline is adapted to the outer contour of the fabric, which can help employees place the fabric, reduce the number of position adjustments, and improve sewing efficiency.

[0068] In practice, Figure 3 The dashed outline in the image represents the outer contour of the fabric.

[0069] Based on the same inventive concept, this application also provides an automatic zipper feeding machine, see reference. Figures 4 to 6 The automatic zipper feeder includes a sewing machine body 6, a zipper sewing template as described in any of the above embodiments, and a pressing member 7. The sewing machine body 6 has a processing platform 61. The zipper sewing template as described in any of the above embodiments is disposed on the processing platform 61. The zipper sewing template can move along a first path and can also move along a second path. The pressing member 7 is installed on the processing platform 61. The pressing member 7 has a pressing end extending above the zipper sewing template. The bottom of the pressing end is in vertical contact with the top of the zipper sewing template to restrict the displacement of the zipper sewing template in the vertical direction.

[0070] The automatic zipper machine provided in this embodiment, compared with the prior art, is equipped with a base plate 1, a partition plate 2, and a pressure plate 3 to fix the fabric and the zipper. When sewing, the pressure plate 3 and the partition plate 2 are opened, the fabric is placed on the base plate 1, the partition plate 2 is flipped so that the partition plate 2 and the base plate 1 clamp the fabric, and then the pressure plate 3 is flipped so that the pressure plate 3 and the partition plate 2 cooperate to clamp the zipper. The partition plate 2 and the pressure plate 3 are fixed by the connecting component 4 to increase the clamping strength. The entire template is moved to the sewing machine, and the sewing machine automatically sews along the first sewing hole to sew the zipper and the fabric together. The entire process uses the partition plate 2 and the pressure plate 3 to fix the fabric and the zipper respectively, and the connecting component 4 to fix the partition plate 2, the pressure plate 3, and the base plate 1. The zipper is finally pressed down, eliminating the need for employees to manually press it constantly, significantly reducing employee involvement, lowering labor intensity, and increasing sewing efficiency. The pressure plate 3 and partition 2 can fix the fabric and zipper in the vertical direction, with a large clamping area. During use, the zipper or fabric will not deviate and deform, improving sewing quality. The zipper sewing template moves automatically on the sewing machine body 6. Employees only need to flip the partition 2 and pressure plate 3 to clamp and fix the zipper and fabric. The connecting component 4 fixes the pressure plate 3 and partition 2 during sewing. The pressure plate 3 and partition 2 respectively fix the zipper and fabric over a large area, preventing the zipper from twisting or deforming during sewing, thus improving sewing quality.

[0071] It should be noted that the processing platform 61 is also equipped with a telescopic drive component that moves along the first path. The telescopic drive component is a telescopic cylinder. The telescopic drive component has a telescopic end that moves along the second path. The telescopic end is connected to the base plate 1 to drive the zipper sewing template to move along the first path or the second path, so as to ensure the normal operation of the sewing work.

[0072] In some embodiments, see Figure 5 and Figure 6The clamping component 7 includes a clamping body and a clamping arm 72 located on one side of the clamping body. The bottom surface of the clamping arm 72 is provided with a bonding plate 73, which forms the clamping end. The clamping body is detachably mounted on the processing platform 61. By setting the clamping arm 72 and the bonding plate 73 on its bottom surface as the clamping end, the clamping plate 3 can be more precisely fitted, facilitating the application of uniform pressure to the zipper by the clamping plate 3. When processing different types or sizes of zippers, the appropriate clamping component 7 can be quickly replaced, improving the versatility and adaptability of the equipment.

[0073] In practice, the main body of the clamping device and the clamping arm 72 are integrally cast.

[0074] In practice, the clamping component 7 is a weight-adding component that stands upright on the processing platform 61 by its own weight. When not sewing, the clamping component 7 can be removed without affecting the placement of the fabric on the base plate 1 or the movement of the base plate 1. When sewing, it is placed in the corresponding position on the processing platform 61 so that the bonding plate 73 is attached to the upper surface of the pressure plate 3. When the pressure plate 3 moves with the base plate 1 on the first path, the bonding plate 73 is always limited at the top of the pressure plate 3 to prevent the pressure plate 3 from being misaligned and affecting the sewing quality.

[0075] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
