Description

Technical Field

[0001] This utility model relates to the field of garment manufacturing technology, specifically a laser-cutting and forming fixture for carrot pants. Background Technology

[0002] The current carrot pants differ from regular pants in their body (especially the hip area), resulting in a different back pocket design. Consequently, the back pocket forming process also differs. It's necessary to ensure a certain distance between the pocket opening on the pant piece and the pocket fabric, with the opening positioned in an arrowhead pattern. Furthermore, the stitching lines on the pocket flap, pocket patch, and pocket opening must be parallel and evenly spaced. This makes the manufacturing process difficult, requiring experienced operators and resulting in low efficiency and yield. The main challenge lies in the need for multiple templates for marking, followed by sequential pocket opening. This requires precise cutting with a cutting machine, and the cut ends must be oriented like arrows. A small arrow distance can easily lead to incomplete or improper cutting. Excessive stitching makes it difficult to shape, which is one of the challenges. Secondly, inaccurate manual positioning makes it difficult to control the needle position during the sewing process with the bag flap or bag patch, easily leading to overstitching or understitching. This results in gaps and slanted twists in the open pocket, requiring rework and adjustment later. Moreover, in actual production, relying solely on cardboard alignment for sewing causes the stitching lines of the bag flap, bag patch, and open pocket to be non-parallel, significantly reducing the overall aesthetics. Finally, the sewing efficiency is low. The process of positioning, marking, opening, attaching the bag flap, and attaching the bag patch takes at least 5-6 minutes to complete, and the multiple runs and disassemblies make it difficult to match the various dimensions, resulting in inaccurate dimensions, low parallelism, and inconsistent product quality.

[0003] In conclusion, the pocket design of existing trousers (carrot pants) still needs further improvement and enhancement. Utility Model Content

[0036] See Figure 1-2 The laser-cutting and forming fixture for carrot pants described in this embodiment is used for opening the back pocket of the pants and for sewing the pocket flap and pocket patch in parallel in one go. This embodiment takes the pocket formed on the back pant piece of carrot pants as an example.

[0037] The molding fixture described in this embodiment includes: a base plate 1, a first pressure plate 2, a second pressure plate 3, and a face plate 4;

[0038] The base plate 1 has a first marking line 11 and a through groove 12 on it;

[0039] The first marking line 11 is used for aligning and laying the pocket piece A. That is, the first marking line 11 is marked according to the size of the edge of the pocket piece A and compared with the opening position (i.e., the position of the through groove 12). During production, it is only necessary to align and lay it with the position of the first marking line 11. It should be noted here that pocket piece A refers to the pocket fabric piece.

[0040] The through groove 12 is configured as a laser-opening pocket groove and a sewing groove (i.e., a first sewing groove 122 and a second sewing groove 123). A forming part 121 extends into the groove from both ends of the through groove 12 along the length direction. The free ends of the two forming parts 121 are respectively set with sharp angles. The first sewing groove 122 and the second sewing groove 123 are formed on the left and right sides of the forming part 121, respectively. The first sewing groove 122 is used to sew the pocket patch piece C to the trouser body piece B and the pocket piece A, while the second sewing groove 123 is used to sew the pocket patch piece D to the trouser body piece B and the pocket piece A.

[0041] It should be noted that the sharp corner edges 121A and connecting lines 121B on the two forming parts 121 on the base plate 1 are configured as laser cutting positions;

[0042] In addition, a first anti-slip layer 5 is attached to the opposite surfaces of the base plate 1 and the first pressure plate 2, and the first anti-slip layer 5 is disposed on the outside of the through groove 12 to restrict the pocket piece A from sliding relative to the base plate 1 and prevent the pocket piece A from being pushed or twisted during the sewing process.

[0043] The first pressure plate 2 is hinged to the base plate 1 and has a second marking line 21 and a first through groove 22.

[0044] The first through groove 22 is provided corresponding to the through groove 12 for the sewing needle to pass through;

[0045] The second marking line 21 is used for laying the trouser body piece B; that is, the second marking line 21 is marked according to the edge size of the trouser body piece B and compared with the first through groove 22. During production, it is only necessary to lay it in alignment with the position of the second marking line 21.

[0046] The second pressure plate 3 is hinged to the first pressure plate 2 and has a second through groove 31 and at least two positioning stops 32 and 33.

[0047] The second through groove 31 corresponds to and matches the first through groove 22, and is also used for the insertion of sewing needles;

[0048] Two positioning strips 32 and 33 are respectively provided on the left and right sides of the second through groove 31 along the length direction. One positioning strip 32 is used for the bag eyebrow piece C to abut against and cover the second through groove 31; the other positioning strip 33 is used for the bag patch piece D to abut against and cover the second through groove 31.

[0049] Among them, an adhesive layer 6 is provided on the second pressure plate 3 and between the two edges of the two positioning baffles 32 and 33 and the second through groove 31, respectively, for adhering the bag eyebrow cut piece C and the bag patch cut piece D, so as to limit the bag eyebrow cut piece C and the bag patch cut piece D from deviating during the sewing process and further improve the sewing quality.

[0050] Panel 4 is hinged to and covers the second pressure plate 3; panel 4 has two matching grooves 41 corresponding to the first sewing groove 122 and the second sewing groove 123. It should be noted that in this embodiment, a partition 42 is formed on panel 4 at the position of the line 121B connecting the sharp corners on the bottom plate 1, so that two matching grooves 41 corresponding to the first sewing groove 122 and the second sewing groove 123 are formed on panel 4.

[0051] The bottom plate 1, the first pressure plate 2, the second pressure plate 3 and the panel 4 are hinged to each other, wherein the hinge position of the panel 4 and the second pressure plate 3 is parallel to the length direction of the through groove 12.

[0052] In addition, it also includes magnetic components 8, which are respectively installed on the base plate 1, the first pressure plate 2, the second pressure plate 3 and the front panel 4, for magnetic clamping of adjacent plates. This ensures that the pocket piece A and the trouser body piece B can be tightly clamped during the laser opening process, and that each piece can be clamped when sewing the pocket eyebrow and pocket patch, ensuring that the sewn pocket is flat and neat.

[0053] More specifically, a second anti-slip layer 7 is attached to the opposite surfaces of the first pressure plate 2 and the second pressure plate 3, and the second anti-slip layer 7 is disposed on the outside of the first through groove 22 to restrict the pant body piece B from sliding relative to the first pressure plate 2. This ensures that each piece can be laid flat without sliding or twisting during the sewing process, and plays a good role in limiting the position.

[0054] More specifically, a soft padding member 9 is provided on the partition plate 42 on the side opposite to the second pressure plate 3. It spans across the two forming parts 121 and is used to press the bag eyebrow cutting piece C and the bag patch cutting piece D. This ensures that the opening position is pressed after the laser opening of the bag, preventing excessive loosening during the sewing process and affecting the sewing quality.

[0055] More specifically, the panel 4 is also provided with a receiving groove 43 for the bag eyebrow piece C to be inserted; after the bag eyebrow piece C is sewn into shape, it covers the sewing position of the bag patch piece D. The other parts of the sewn bag eyebrow piece C can be placed in the receiving groove 43 and passed through the panel 4, so that the bag patch sewing position is exposed, which is convenient for sewing and observing the sewing status.

[0056] In actual preparation and use: see Figure 1-8 ;

[0057] (1) A transparent acrylic sheet is used to make a base plate 1, a first pressure plate 2, a second pressure plate 3 and a panel 4, and two adjacent plates are hinged together with adhesive tape. It should be noted that the hinge position of the second pressure plate 3 and the panel 4 is perpendicular to the hinge position of the other plates. In addition, mounting holes for the installation of magnetic components 8 are opened on the base plate 1, the first pressure plate 2, the second pressure plate 3 and the panel 4 respectively, and each magnetic component 8 is aligned and installed.

[0058] (2) The base plate 1 is precisely engraved with a through groove 12 with two forming parts 121 and a first marking line 11. The free part 121 is set with a sharp angle. The laser then performs laser opening along the edge 121A of the sharp angle and the line 121B connecting the two sharp angles. The forming part 121 forms a first sewing groove 122 and a second sewing groove 123 on both sides along the length direction. In addition, a first anti-slip layer 5 is laid on both sides of the through groove 12. It is formed by attaching abrasive paper, or it can be an anti-slip layer made of other anti-slip materials.

[0059] (3) The first pressure plate 2 has a first through groove 22 and a second marking line 21. Sandpaper (i.e., the second anti-slip layer 7) is attached to the upper and lower surfaces of the first pressure plate 2 respectively. The sandpaper is thin and will not affect the sewing.

[0060] (4) The second pressure plate 3 has two positioning strips 32 and 33 fixed on its upper surface with strong adhesive. The two positioning strips 32 and 33 are parallel to the length direction of the second through groove 31. Then, two adhesive layers 6 are fixed in the area from the positioning strips 32 and 33 to the second through groove 31. The adhesive layer 6 can be made of adhesive paper.

[0061] (5) Panel 4, on which a receiving groove 43 and two alignment grooves 41 are formed. The two alignment grooves 41 are formed on the left and right sides with the partition 42 as the boundary, and are respectively opposite to the first sewing groove 122 and the second sewing groove 123. The receiving groove 43 is used to place the excess part of the bag eyebrow cut piece C.

[0062] In addition, a soft pad pressing member 9 is attached to the side of the partition 42 opposite to the bottom plate 1, and is pressed on the bag opening position to prevent the cut pieces of the bag opening from being too loose during sewing, affecting the sewing quality.

[0063] During use:

[0064] (1) As Figure 3 shown, place and lay the pocket cut piece A (i.e., the pocket cloth) corresponding to the first marking line 11 of the bottom plate 1. After adjusting the alignment, cover the first pressing plate 2 on the pocket cut piece A to clamp the pocket cut piece A, and prevent slipping through the first anti-slip layer 5. Also, the first pressing plate 2 is tightly pressed against the bottom plate 1 through the magnetic attraction member 8 to tightly clamp the pocket cut piece A.

[0065] (2) As <^ Figure 4 shown, place and lay the trouser body cut piece B corresponding to the second marking line 21 on the first pressing plate 2. After adjusting the alignment, cover the second pressing plate 3 on the trouser body cut piece B to clamp the trouser body cut piece B, and also prevent slipping through the second anti-slip layer 7.

[0066] (3) As Figure 5 shown, then first perform alignment laser cutting on it through a sewing machine with a laser. The laser bag opening track is formed along the sharp corner edge 121A of the forming part 121 and the connection line 121B of the two sharp corners, forming a shape similar to the Chinese character "工" (worker). After the bag opening is completed, withdraw, and wait to lay the bag eyebrow cut piece C.

[0067] (3) As Figure 6 shown, take the bag eyebrow cut piece C. First, fold the bag eyebrow cut piece C in half, and place the folded edge against the positioning bar 32 close to the first sewing groove 122. Then, flip the panel 4 and cover it to clamp the folded bag eyebrow cut piece C with the second pressing plate 3. Then, place it on the sewing machine to sew the first stitch line, so that the bag eyebrow, the trouser body, and the trouser pocket are sewn together.

[0068] After sewing the bag eyebrow, drag the free end part of the bag eyebrow cut piece C towards the first sewing line direction to avoid covering the second sewing groove 123. In addition, to prevent the phenomenon of fabric stacking, place the free end part of the bag eyebrow cut piece C in the receiving groove 43, so that the panel 4 can be smoothly covered on the second pressing plate 3.

[0069] As Figure 7 、 8As shown, then take the bag patch piece D, place its edge against the inside of another positioning strip 33, lay it in the direction of the second through groove 31, cover the second through groove 31, then cover the top panel 4, and sew the second seam line along the second seam groove 123.

[0070] (5) Flip the pocket patch D and the pocket eyebrow patch C into place to form a complete back pocket shape.

[0071] This utility model provides a laser-cut pocket-forming fixture for carrot pants. It features a simple structure, easy manufacturing, and low cost. The fixture combines laser pocket cutting with template positioning and sewing, forming the pocket opening, pocket flap, and pocket patch in a single, continuous process. No drawing or sizing is required. It precisely sews the pocket flap and pocket patch parallel to the pocket opening, resulting in a high overall aesthetic appeal and significantly reduced processing difficulty. The laser-cut pocket opening with sharp corners is achieved through a base plate, a first pressure plate, and a second pressure plate, resulting in a square pocket. The pocket flap and pocket patch can be sewn without disassembly. After the pocket flap is formed, it can be flipped open to sew the pocket patch to the other half, ensuring the pocket flap, pocket patch, and pocket opening are parallel and of consistent quality. More importantly, it significantly improves production efficiency, forming a single back pocket in only 30-40 seconds, more than six times the original efficiency.
