Currently, the industry commonly uses manual assistance with sewing machines for gripper strip sewing. However, manually folding the gripper strips makes it difficult to accurately control the width, resulting in large deviations in the gripper strip width and inconsistent garment appearance. Furthermore, manually adjusting the gripper strip position and correcting deviations takes up a significant amount of time, which cannot meet the efficiency requirements of mass production. Utility Model Content

[0003] The purpose of this invention is to provide a front panel facing clamping strip arc-shaped shaping and export sewing fixture, which is easy to operate, ensures consistent clamping strip width and uniform feed, avoids manual adjustment, and improves production efficiency.

[0004] To achieve the above objectives, this utility model provides a front panel facing clip arc-shaped shaping and guiding sewing fixture, including a connecting seat and guide presser feet; the connecting seat includes an integrally formed fixing piece and a guide piece; the fixing piece is laid flat on the sewing machine table and has fixing holes for fixing to the table; the guide piece is fixed on the fixing piece and has a guide edge extending from the outside of the sewing machine head to the bottom of the sewing machine head; the guide edge has a certain safety distance from the sewing machine table; multiple guide presser feet are evenly arranged along the guide edge; each includes a U-shaped clamping plate that snaps onto the guide edge; the U-shaped groove of the clamping plate is engaged with the guide edge, and the groove openings are respectively fixed to the upper and lower surfaces of the guide piece; the U-shaped groove and the guide piece form a U-shaped clip folding area.

[0005] With the above structure, this sewing fixture provides specialized structural support for the arc-shaped shaping and sewing of the front panel facing strip through the cooperation of the connecting seat and the guide presser foot. The fixing plate of the connecting seat is laid flat on the sewing machine table and has fixing holes for easy fixation of the fixture to the table; the guide plate has a guide edge to provide a path for guiding the facing strip; the guide presser foot is set along the guide edge, and its U-shaped groove and the guide plate form a folding area for the facing strip, so that the fabric strip can be folded under the limitation of the guide edge and the U-shaped groove, which facilitates subsequent sewing and improves sewing efficiency and accuracy.

[0006] Preferably, the guide plate is a slanted plate structure with one end fixed to the fixed plate and the other end extending upward at an angle; the guide edge is located at the end of the guide plate away from the fixed plate. The guide plate's slanted plate structure, with one end fixed to the fixed plate and the other end extending upward at an angle, and the guide edge located at the end away from the fixed plate, ensures a safe distance between the guide edge and the sewing machine table, preventing the guide presser foot from squeezing the fabric at the bottom of the device and scratching the sewing machine table.

[0010] Preferably, a limiting block is clamped between one side of the slot wall of the clamping plate and the guide plate, and between the other side of the slot wall of the clamping plate and the guide plate; the limiting block is fixed to the clamping plate in an adjustable position; by adjusting the position of the limiting block, the distance between the limiting block and the guide edge is changed, thereby adjusting the width of the folded area of ​​the threaded strip. This design achieves flexible adjustment of the folded width of the threaded strip, can be adapted to the processing of different specifications of clamped threaded strips, and improves the versatility of the tooling.

[0011] Preferably, the groove wall of the card plate is provided with an elongated hole extending towards the guide edge; the limiting block is slidably installed in the elongated hole; the limiting block is provided with a threaded post extending out of the elongated hole; a nut is fixed to one end of the threaded post extending out of the elongated hole. This structure is easy to operate; loosening the nut allows the limiting block to slide along the elongated hole, and tightening the nut after adjustment locks the position, providing high adjustment accuracy and reliable fixation.

[0012] Preferably, the guide plate is provided with clearance holes, and the two limiting blocks are connected by a connecting post passing through the clearance holes. The connecting post enables the synchronous movement of the two limiting blocks, ensuring that the width of the two sides of the folded area of ​​the toothed strip is symmetrical, and avoiding uneven tooth width caused by unilateral offset; the clearance holes provide movement space for the connecting post without affecting the structural strength of the guide plate.

[0013] Preferably, multiple connecting posts are provided. The use of multiple connecting posts enhances the stability of the connection between the two limiting blocks, preventing tilting of the limiting blocks during sliding or use, and ensuring consistent adjustment of the folded width. Furthermore, the axes of all connecting posts are perpendicular to the surface of the guide plate, preventing the connecting posts from getting stuck against the inner wall of the clearance hole.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are: This utility model, a front panel facing clip arc-shaped guide sewing fixture, solves the technical problems of inaccurate precision control and inability to meet the efficiency requirements of mass production in existing technologies. This utility model provides specialized structural support for the arc-shaped guide sewing of the front panel facing clip through the cooperation of a connecting seat and a guide presser foot. The fixing plate of the connecting seat lies flat on the sewing machine table and has fixing holes for easy fixation of the fixture to the table; the guide plate has a guide edge to provide a path for guiding the clip; the guide presser foot is set along the guide edge, and its U-shaped groove, together with the guide plate, forms a folding area for the clip, allowing the fabric strip to be folded under the constraint of the guide edge and the U-shaped groove, facilitating subsequent sewing and improving sewing efficiency and accuracy.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] The orientations mentioned in this specification are based on the orientation of the front panel hanging clip arc-shaped shaping and leading sewing tool of this utility model during normal operation. They do not limit the orientation during storage and transportation, but only represent relative positional relationships, not absolute positional relationships.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, a front panel facing clip arc-shaped shaping and guiding sewing fixture is used for sewing the clip between the front panel and the facing.

[0020] A front panel hanging clip with arc-shaped shaping and export sewing fixture includes a connecting seat 1 and a guide presser foot 2.

[0021] The connecting base 1 includes an integrally formed fixing plate 11 and a guide plate 12. The fixing plate 11 is laid flat on the sewing machine table and has fixing holes 111 for fixing to the table. The fixing holes 111 are oblong holes, and the fixing plate 11 is fixed to the table by at least two screws. The oblong hole design allows for fine adjustment of the position of the connecting base 1 along the length of the hole, ensuring that the guide edge 121 is precisely aligned with the sewing path of the sewing machine head, avoiding sewing misalignment caused by installation deviation. The guide plate 12 is fixed to the fixing plate 11 and has a guide edge 121 extending from the outside of the sewing machine head to the bottom of the sewing machine head.

[0022] Furthermore, because the feed bar is clamped between the front panel and the fabric, fabric pieces need to be inserted at both the bottom and top of the device. To prevent the guide presser foot 2 from squeezing the fabric piece at the bottom of the device and to prevent the guide presser foot 2 from scratching the sewing machine table, the guide edge 121 is kept at a safe distance from the sewing machine table. The safe distance ranges from 5 to 10 mm to avoid squeezing the bottom fabric piece and scratching the table.

[0023] like Figure 1 and Figure 4 As shown, the specific method is as follows: the guide plate 12 is an inclined plate structure with one end fixed to the fixing plate 11 and the other end extending upward at an angle; the inclination of the guide plate 12 and the fixing plate 11 is 3-5°, and in this embodiment, the inclination of the guide plate 12 and the fixing plate 11 is 5°. The guide edge 121 is set on the end of the guide plate 12 away from the fixing plate 11. Through this structure, a certain safe distance can be achieved between the guide edge 121 and the sewing machine table surface.

[0024] Furthermore, the guide plate 12 has a fan-shaped structure, with the guide edge 121 set on the arc edge and the fixing plate 11 fixed on the right-angle edge. The fan-shaped structure of the guide plate 12 makes the guide edge 121 form a natural smooth arc, which can realize the insertion of the toothed strip from one side and ensure the consistency and accuracy of the arc-shaped shaping of the toothed strip.

[0025] Furthermore, the end of the guide edge 121 is provided with a feed angle 122 extending towards the sewing machine head. The feed angle 122 extends downward at an angle, and its width gradually decreases from the guide edge 121 towards the sewing machine head. The downward extension of the feed angle 122 can press the fabric at the bottom of the device tightly, while the gradually decreasing feed angle 122 can guide the folded feed dog smoothly into the area under the presser foot of the sewing machine, reducing jamming and deviation during feed dog delivery and improving sewing continuity.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, multiple guide feet 2 are evenly arranged along the guide edge 121. In this embodiment, four are provided, but in actual applications, three or five can be designed as needed. This embodiment does not limit this. The guide foot 2 includes a U-shaped retaining plate 21 that is fastened to the guide edge 121. The U-shaped groove of the retaining plate 21 is engaged with the guide edge 121, and its groove opening is fixed to the upper and lower surfaces of the guide piece 12, respectively. In this embodiment, it is fixed by welding. The U-shaped groove and the guide piece 12 form a U-shaped toothed folding area.

[0027] In use, the fabric strip C is inserted into the folding area of ​​the toothed strip and moves from one end of the guide edge 121 to the other end. Under the constraint of the guide edge 121 and the U-shaped groove, the fabric strip C is folded in half.

[0028] Example 2: This embodiment is a further improvement on Embodiment 1.

[0029] Because the width of the fabric strip C (which becomes a toothed strip after being folded in half) is not fixed, and if the width of the folded area of ​​the toothed strip is longer than the width of the fabric strip C, it can easily cause a deviation in the width of the toothed strip. Therefore, in this embodiment, a limiting block 3 is clamped between one side of the groove wall of the clamping plate 21 and the guide piece 12, and between the other side of the groove wall of the clamping plate 21 and the guide piece 12. The limiting block 3 is fixed to the clamping plate 21 in an adjustable position. By adjusting the position of the limiting block 3, the distance between the limiting block 3 and the guide edge 121 is changed, thereby adjusting the width of the folded area of ​​the toothed strip. The setting of the limiting block 3 realizes the flexible adjustment of the folded width of the toothed strip, which can be adapted to the processing of toothed strips of different specifications (such as width 5mm-15mm), improving the versatility of the tooling.

[0030] The groove wall of the clamping plate 21 has an elongated hole 211 extending towards the guide edge 121; the limiting block 3 is slidably installed in the elongated hole 211; the limiting block 3 has a threaded post 31 extending out of the elongated hole 211; a nut 32 is fixed to one end of the threaded post 31 extending out of the elongated hole 211. The limiting block 3 is slidably installed on the clamping plate 21 through the elongated hole 211, one end of the threaded post 31 is fixedly connected to the limiting block 3, and the other end passes through the elongated hole 211 and extends to the outside of the clamping plate 21. The nut 32 is threadedly connected to the end of the threaded post 31 extending out of the clamping plate 21. By tightening the nut 32, the limiting block 3 is fixed to the clamping plate 21. This structure is easy to operate. Loosening the nut 32 allows the limiting block 3 to slide along the elongated hole 211, and tightening the nut 32 after adjustment locks the position. The adjustment accuracy is high and the fixation is reliable.

[0031] Furthermore, the guide plate 12 is provided with a clearance hole 123, and the two limiting blocks 3 are connected by a connecting post 33, which passes through the clearance hole 123. The connecting post 33 enables the synchronous movement of the two limiting blocks 3, ensuring that the width of the two sides of the folded area of ​​the toothed strip is symmetrical, and avoiding uneven tooth width caused by unilateral offset; the clearance hole 123 provides the moving space for the connecting post 33, without affecting the structural strength of the guide plate 12. There are multiple connecting posts 33, three in this embodiment, but two or one can also be used in actual applications. The axes of the multiple connecting posts 33 are all perpendicular to the plate surface of the guide plate 12. The multiple connecting posts 33 can enhance the stability of the connection between the two limiting blocks 3, prevent the limiting blocks 3 from tilting during sliding or use, ensure the consistency of the folded width adjustment, and prevent the connecting post 33 from getting stuck with the inner wall of the clearance hole 123, as the axis direction is perpendicular to the guide plate 12.

[0032] In use, according to the specifications of the toothed strip, loosen the nut 32, slide the limiting block 3 along the long strip hole 211, adjust the distance between the limiting block 3 and the guide edge 121 so that the width of the toothed strip folding area matches the toothed strip specifications, tighten the nut 32 to lock the limiting block 3; put the toothed strip into the toothed strip folding area from the entrance end of the guide presser foot 2, and the toothed strip will automatically fold under the action of the U-shaped groove; start the sewing machine, and the folded toothed strip will move along the inclined arc path of the guide edge 121, and smoothly enter the sewing area of ​​the machine head through the feed angle 122 to complete the sewing of the front panel facing toothed strip.

[0033] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
