A needle 6 is provided below the sewing machine 7 on one side of the support rod 5, and the needle 6 is located directly above the sewing groove 31 and the sewing groove 41. The principle and structure of the sewing machine 7 and the mechanism of the needle 6 are existing technologies and will not be described in detail here.

[0014] like Figure 3-4As shown, the lower guide rail 1 includes a base plate 18. The two sides of the base plate 18 are bent inward to form bent edges 12. A baffle 13 is connected between the bottom of the two bent edges 12. A bottom edge channel 14 is formed between the baffle 13 and the base plate 18. The two bent edges 12 and the two sides of the baffle 13 form bent edge channels 16. The two bent edge channels 16 are connected to the bottom edge channel 14 at the bottom, which is used to bend the two sides of the fabric inward. The bottom edge channel 14 and the bent edge channel 16 are located on the same side of the base plate and have an inlet 11. The other side has an outlet 15. The distance between the two bent edges 12 in the direction of the inlet 11 and the outlet 15 gradually approaches, and the width of the base plate 18 gradually narrows, so that the width of the outlet 15 is smaller than the width of the inlet 11, which facilitates the guidance and shaping of the fabric.

[0015] like Figure 5-6 As shown, the upper guide rail 2 includes a substrate 27. The two sides of the substrate 27 are bent inward to form bent edges 22. A baffle 23 is connected between the bottom of the two bent edges 22. A fabric feeding channel 24 is formed between the baffle 23 and the substrate 27. The fabric feeding channel 24 is provided with a fabric inlet 21 on one side of the substrate and a fabric outlet 25 on the other side. The distance between the two bent edges 22 in the direction of the fabric inlet 21 and the fabric outlet 25 gradually approaches, and the width of the substrate 27 gradually narrows, so that the width of the fabric outlet 25 is smaller than the width of the fabric inlet 21, which facilitates the guidance and shaping of the fabric.

[0016] An opening 17 is provided between the baffle 13 of the lower guide rail 1 and the fabric outlet 15, and the opening 17 is connected to the bottom edge channel 14; an opening 26 is provided on the baffle 23 of the upper guide rail 2, and the opening 26 is connected to the fabric inlet channel 24; the opening 17 and the opening 26 are used by the operator to insert tools to pull and guide the fabric through the lower guide rail 1 and the upper guide rail 2 for the first time.

[0017] like Figure 7-8 As shown, the two-color hook includes an upper fabric 9 and a lower fabric 91. The upper fabric 9 is located in the fabric feeding channel 24 of the upper guide rail 2. The lower fabric 91 includes a bottom edge 93 and two bent fabric edges 92 on both sides. The bottom edge 93 is located in the bottom edge channel 14 of the lower guide rail 1, and the bent fabric edges 92 are located in the bent edge channel 16 of the lower guide rail 1. The upper fabric 9 is located above the bent fabric edges 92 of the lower fabric 91.

[0018] Working principle: The base plate 3 is placed on the workbench, and the gap between the top plate 4 and the base plate 3 is adjusted by the push rod motor 8 to facilitate the introduction of the fabric. First, one end of the lower fabric 91 is inserted into the inlet 11 of the lower guide rail 1. The lower fabric 91 is then led out from the outlet 15 through the opening 17. At this time, as the curved edge channels 16 on both sides of the lower guide rail 1 gradually approach each other and the bottom edge channel 14 gradually narrows, the two sides of the lower fabric 91 are bent inward and overlapped to form a state ready for sewing. Then, one end of the upper fabric 9 is inserted into the inlet 21 of the upper guide rail 2, and the upper fabric 9 is pulled out from the outlet 25 through the opening 26. The shape of the upper fabric 9 after being pulled out does not change. The gap between the top plate 4 and the bottom plate 3 is used to limit and press the bent lower fabric 91 and the upper fabric 9 covering the lower fabric 91 to prevent deformation. The sewing machine 7 is started, and the needle 6 sews the upper fabric 9 and the lower fabric 91 with thread 94 through the sewing groove 31 and sewing groove 41 on the top plate 4 and the bottom plate 3. During the sewing process, the sewn upper fabric 9 and the lower fabric 91 at the outlet gap of the top plate 4 and the bottom plate 3 can be slowly pulled to continue sewing.

[0019] This invention guides two different colored fabrics by setting up an upper guide rail 2 and a lower guide rail 1. The bottom edge channel 14 and the curved edge channel 16 of the lower guide rail 1 are connected, so that the fabric bends inward on both sides when it passes through, forming a state ready for sewing. The two colored fabrics meet and overlap at the exit of the upper guide rail 2 and the lower guide rail 1 for one-time sewing. The distance between the top plate 4 and the bottom plate 3 is adjusted by the guide rod to press and limit the overlapping state of the two fabrics, preventing deformation during sewing and affecting the sewing accuracy. The needle 6 is started to sew. By pulling the two fabrics at the exit gap of the top plate 4 and the bottom plate 3, they can be sewn in one go, improving processing efficiency and sewing accuracy, and reducing the difficulty for operators.
