Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] This application discloses a garment sewing device; see [link to relevant documentation] Figures 1 to 5 as well as Figure 7 , Figure 8As shown, the assembly includes: a processing table 1, a sewing machine 2, and template components 3 for fixing the fabric on the left and right sides respectively; the sewing machine 2 is installed on the processing table 1 for sewing objects fixed on the templates; the template components 3 are placed on the processing table 1 for limiting the processing position of the sewing objects; wherein, the template components 3 include a male mold component 31, a female mold component 32, and a limiting component 33; the male mold component 31 is used to limit the sewing of the fabric and zipper strip; the female mold component 32 is used to limit the sewing of the fabric and zipper head; the limiting component 33 is installed on the male mold component 31 and the female mold component 32 for positioning the fabric spread around the male mold component 31 or the female mold component 32; both the male mold component 31 and the female mold component 32 are composed of an upper template 301 and a lower template 302; the lower template 302 is used to limit the sewing of the fabric; the upper template 301 is used to limit the sewing of the zipper strip or zipper head.

[0037] See Figure 7 and Figure 8 As shown, the lower template 302 includes a first cutting piece 3022, a second cutting piece 3023, and a sealant 3024. The first cutting piece 3022 is mounted on the second cutting piece 3023, and the sealant 3024 is mounted between the sides of the first cutting piece 3022 and the second cutting piece 3023 that are close to each other. Both the first cutting piece 3022 and the second cutting piece 3023 have reserved grooves for the sewing machine 2's cutting tool. The first cutting piece 3022 is also equipped with a chip that senses the sewing machine 2. When the first cutting piece 3022 and the second cutting piece 3023 are placed in the appropriate position of the sewing machine 2, the sewing machine 2 senses the chip to proceed to the next step of operation and automatically sew the fabric.

[0038] The materials used for sewing the garment include an inner lining and an outer fabric. The inner lining is larger than the outer fabric, which helps to accommodate more internal space. The first piece 3022 and the second piece 3023 are both made of PVC material and are transparent. The two pieces are the same size and volume. The two pieces are side-bonded by adhesive 3024. The adhesive 3024 connects the first piece 3022 and the second piece 3023, so that the garment is placed between the two pieces. This not only helps to hold the garment together, but the smaller gap between the pieces also increases the tightness of the garment and improves the flatness of the sewing.

[0039] The upper template 301 includes a zipper strip processing plate 3012 and a zipper head processing plate 3013; both the zipper head processing plate and the zipper head processing plate 3013 are composed of three plates.

[0040] See Figure 5As shown, the zipper processing plate 3012 includes a first clamping plate 3001, a second clamping plate 3002, and a third clamping plate 3003, which are arranged sequentially from top to bottom. The zipper head processing plate 3013 has the same stacking clamping plates as the zipper processing plate 3012. The third clamping plate 3003 of the zipper head processing plate 3013 also has a receiving groove. The first clamping plate 3001, the second clamping plate 3002, and the third clamping plate 3003 are all made of PVC material and are transparent. They are also bonded to each other using a sealing glue 3024, which helps to reduce the gap between adjacent clamping plates and improve the compression of the fabric. The difference between the zipper head processing plate 3013 and the zipper processing plate 3012 is that the zipper head processing plate 3013 has a receiving groove for placing the zipper head. The rest of the shape and size are the same.

[0041] See Figure 8 As shown, the limiting component 33 includes adhesive 331, toothed needles 332, and sponge strips 333; the second cut piece 3023 is also coated with scribe lines of the same specifications as the fabric, the shape of which is consistent with the shape of the fabric to be sewn. The scribe lines on the second cut piece 3023 facilitate the limiting and positioning of the inner lining and outer fabric when they are placed, ensuring that all fabrics in the same batch are placed in the same position; the adhesive 331 is provided with an array and installed on the second cut piece 3023; the sponge strips 333 are installed on the second cut piece 3023 and located at the four corners of the fabric; the toothed needles 332 are arranged on the adhesive 331. The first piece 3022 is positioned on one side and faces the same direction as the adhesive 331. Adhesive 331 and toothed needles 332 are also installed on the end face of the first piece 3022 near the second piece 3023. When the fabric is placed on the second piece 3023, it is held in place by the adhesive 331 to prevent the fabric from shifting. The adhesive 331 and toothed needles 332 are arranged in an arc shape and in strips to better fix the fabric on the second piece 3023. After sewing, the worker can easily tear off the adhered fabric along the direction of the toothed needles 332. The sponge strip 333 can position the fabric around its perimeter.

[0042] See Figure 2 and Figure 4 The side where the adhesive 331 and the toothed needle 332 are attached to each other from left to right is called the rope position. The adhesive 331 and the toothed needle 332 are arranged alternately. When the sewing device 2 sews the fabric, it plays the role of gathering the thread ends of the fabric.

[0043] The reserved groove on the second cut piece 3023 is also equipped with adhesive 331 and toothed needle 332, and the direction of the adhesive 331 and toothed needle 332 is opposite to that of the end face of the first cut piece 3022. The placed adhesive 331 and toothed needle 332 can prevent the fabric from slipping when sewing along the track, and play a certain limiting role.

[0044] The first clamping plate 3001, the second clamping plate 3002, and the third clamping plate 3003 are all provided with through grooves, and the through area gradually decreases from bottom to top; the through groove on the third clamping plate 3003 is also equipped with an insert strip; the through groove on the second clamping plate 3002 is used to place a zipper strip or chain head.

[0045] See Figure 1 As shown, the sewing device 2 includes a sewing part 21, a transmission part 22, and a clamping part 23; the sewing part 21 is mounted on the processing table 1 and is used to sew the fabric, zipper, and chain belt defined on the male mold component 31 or the female mold component 32; the transmission part 22 is mounted on the processing table 1 and is used to drive the male mold component 31 or the female mold component 32 to move; the clamping part 23 is mounted on the transmission part 22 and is used to clamp the upper template 301 and the lower template 302.

[0046] The sewing part 21 contains a sewing needle, a knife, and a pre-reserved thread. The transmission part 22 contains a bracket, a servo motor, and a threaded rod. The processing table 1 has a guide groove perpendicular to the bracket. The control motor on the back of the processing table 1 moves the sewing part 21 longitudinally. The servo motor controls the threaded rod to move the clamping part 23 on the bracket laterally, thereby ensuring the sewing of different positions of the fabric. The clamping part 23 has a push cylinder and a clamping plate. One side of the push cylinder is threadedly engaged with the threaded rod. The threaded rod drives the push cylinder to move laterally. The clamping plate on the lifting end of the push cylinder and the surface of the processing table 1 approach each other. By lifting or retracting the push cylinder, the male mold component 31 or female mold component 32 on the surface of the processing table 1 are pressed together.

[0047] See Figure 4 As shown, the sewing machine 2 follows the following stitching path on the fabric: After lifting the blade, the sewing machine 2 automatically maintains a certain distance from the fabric. After clamping the lower template 302, the original positioning point moves from point a along an arc-shaped trajectory to point b. Upon reaching point b, the sewing machine 2 lifts the blade and moves to point c, continuing to sew along the arc-shaped trajectory to point d. After point d, the blade is automatically lifted and moved to point e. At point e, the blade is sewn along the arc-shaped trajectory to point f. At point f, the blade is automatically lifted and moved to point g. At point g, the blade is sewn along the arc-shaped trajectory to point h. At point h, the blade is lifted and moved to point i. At point i, the blade is sewn along the arc-shaped trajectory to point j. At point j, the blade is automatically lifted and moved to point m. The sewing between points m and n moves back and forth along the arc-shaped trajectory. Finally, the blade is automatically lifted and returned to its original position, and the clamping part 23 is released.

[0048] This application also discloses a fabric sewing process; see [link to relevant documentation]. Figure 6 As shown, the process steps are as follows:

[0049] S101: Cut out fabric and lining of the same shape and size. Cut the lining and outer fabric to a sufficient size and place them on one side for preparation. When sewing each set of fabric, take the lining and outer fabric respectively and stack them from the inside to the outside.

[0050] S102: The inner lining and the outer fabric are placed on the second cut piece 3023 marked with lines. The edges of the fabric are positioned by the sponge strip 333. The first cut piece 3022 is flipped over and laid on the inner lining and the outer fabric.

[0051] S103: Sewing equipment 2 sews the inner lining and outer fabric together by setting a trajectory route and fixing them in place;

[0052] S104: The insert is placed in the through groove of the third clamping plate 3003, the second clamping plate 3002 is flipped over and laid on the insert, the zipper strip or chain head is placed in the through groove of the second clamping plate 3002, the first clamping plate 3001 is laid on the second zipper strip or chain head, and the upper template 301 with the zipper strip or chain head placed is neatly stacked on the lower template 302. The sewing device 2 further sews the upper template 301 and the lower template 302 in the defined positions.

[0053] S105: The sewn male mold component 31 and female mold component 32 are removed from the processing table 1 and sewn together along the zipper and chain head strap on one side close to each other.

[0054] Compared to existing technologies, the use of male mold component 31, female mold component 32, limiting component 33, and sewing equipment 2 for sewing fabric reduces the time and effort required for traditional manual sewing, decreases labor costs, and effectively improves sewing efficiency. The male mold component 31, female mold component 32, and limiting component 33 maintain the flatness of the fabric during each part of the sewing process, preventing the fabric from being pulled by the sewing thread and avoiding any deviation that could affect the sewing quality. The automated sewing operation of the male mold component 31 and female mold component 32 on the sewing equipment 2 further reduces manual labor during production, improving the intelligence and automation level of fabric sewing production.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
