[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1-3 As shown, the new device for fitting large and small lace includes a lace sewing assembly 1 disposed above the sewing machine workbench; the lace sewing assembly 1 includes a positioning rod 11, a first limiting part 12 and a second limiting part 13; the positioning rod 11 is installed on the top of the sewing machine workbench; the first limiting part 12 is rotatably disposed outside the positioning rod 11; the second limiting part 13 is rotatably disposed outside the positioning rod 11 and located below the first limiting part 12.

[0025] The lace to be processed is divided into large lace and small lace. When it is necessary to sew the large and small lace together, first place the small lace above the second restrictive part 13, and then place the large lace on one side of the first restrictive part 12 and above the second restrictive part 13, so that the positions of the large and small lace overlap. Then the sewing machine is started and the overlapping positions of the large and small lace are sewn together. This allows the worker to quickly complete the sewing of the large and small lace by simply pulling the lace by hand. Before the improvement, the sewing time for large and small lace was 33 seconds per piece, with a rework rate of 15%. After the improvement, the sewing time for large and small lace was 10 seconds per piece, and the rework rate was only 1%. The production efficiency was increased by 69%, which greatly improved the production efficiency and the production qualification rate.

[0026] See Figures 2-4 As shown, the first limiting part 12 is L-shaped.

[0027] The first limiting part 12 can be rotated at an angle along the positioning rod 11, which can improve the applicability of the first limiting part 12.

[0028] See Figures 4-6 As shown, the lace sewing assembly 1 also includes a sliding part 14; the sliding part 14 is slidably disposed on the outside of the first limiting part 12; the top of the sliding part 14 is provided with a kidney-shaped hole 141 located above the first limiting part 12.

[0029] The large lace should be placed on top of the sliding part 14, and the large lace can slide on the sliding part 14. The sliding part 14 can slide along the first limiting part 12, so that the position of the sliding part 14 on the first limiting part 12 can be changed, and the stitching position of the large lace on the sliding part 14 can be adjusted.

[0030] See Figure 3 and Figure 4 As shown, the lace sewing assembly 1 also includes a locking bolt 15; the locking bolt 15 is disposed on the top of the sliding part 14 and above the kidney hole 141, and the locking bolt 15 can be screwed in by means of thread to abut against the top of the first limiting part 12 and restrict the position of the sliding part 14 to the outside of the first limiting part 12.

[0031] When the position of the sliding part 14 on the first limiting part 12 changes, the locking bolt 15 should first be rotated in the opposite direction until the locking bolt 15 loses its clamping effect on the first limiting part 12. Only then can the sliding part 14 slide on the first limiting part 12, thereby realizing the adjustment of the position of the sliding part 14 and preventing the sliding part 14 from sliding freely on the first limiting part 12.

[0032] See Figure 4 and Figure 5 As shown, the second limiting part 13 has a through groove 131 in the middle for the lace to pass through; the through groove 131 is trapezoidal in shape, and the through groove 131 and the first limiting part 12 are on the same horizontal plane.

[0033] The small lace trim can be placed in the through slot 131 opened on the second limiting part 13 and located below the large lace trim. In this state, the stitching lines of the large and small lace trims can overlap, allowing the sewing machine to perform sewing work.

[0034] See Figure 6 As shown, the end face of the sliding part 14 is provided with a limiting groove 142 for the lace to pass through; the limiting groove 142 is trapezoidal in shape; the limiting groove 142 is located above the through groove 131.

[0035] The large lace can be placed in the limiting groove 142 opened on the sliding part 14 and located above the small lace. In this state, the seam lines of the large lace and the small lace can overlap, which facilitates the sewing machine to perform sewing work.

[0036] See Figure 5 and Figure 6 As shown, the sliding part 14 is made of a rigid material.

[0037] The sliding part 14 is preferably made of a rigid iron material.

[0038] See Figure 5 and Figure 6As shown, the first limiting part 12 and the second limiting part 13 are both made of rigid materials.

[0039] The first limiting part 12 and the second limiting part 13 are preferably made of rigid iron.

[0040] Working principle: When sewing large and small lace trims, the small lace trim to be processed is first placed above the second restrictive part 13. Then, the large lace trim to be processed is placed on one side of the first restrictive part 12, ensuring it is above the second restrictive part 13 so that their positions overlap. The sewing machine is started to sew the overlapping area of ​​the large and small lace trims. During this process, the worker only needs to hold the large and small lace trims to quickly complete the sewing, significantly improving efficiency. Before the improvement, sewing large and small lace trims took 33 seconds per piece, with a rework rate of 15%; after the improvement, the time was reduced to 10 seconds per piece, the rework rate dropped to 1%, production efficiency increased by 69%, and the production qualification rate was greatly improved. The first restrictive part 12 can be adjusted along the positioning rod 11 to enhance its applicability. The large lace trim should be placed on top of the sliding part 14 and be able to slide. The sliding part 14 can slide along the first restrictive part 12, changing its position and simultaneously adjusting the sewing position of the large lace trim on the sliding part 14. When adjusting the position of the sliding part 14, the locking bolt 15 must first be rotated in the opposite direction until it loses its clamping effect on the first limiting part 12. Only then can the sliding part 14 slide on the first limiting part 12 to achieve position adjustment and prevent the sliding part 14 from sliding freely. The small lace can be placed in the through groove 131 of the second limiting part 13, located below the large lace. At this time, the seam lines of the two overlap, and the sewing machine can sew them together. The large lace can also be placed in the limiting groove 142 of the sliding part 14, located above the small lace, similarly achieving seam line overlap and facilitating the operation of the sewing machine. The sliding part 14, the first limiting part 12, and the second limiting part 13 are preferably made of rigid iron material.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
