The mounting plate is disposed at the bottom of the guide plate and is fixed to the worktable of a sewing machine by fastening screws. Two parallel guide holes for fabric strips are provided on the guide plate, and the fabric strip enters from one guide hole and exits from the other guide hole.

[0006] Furthermore, a limiting plate is installed between the guide plate and the substrate, and a first adjustment hole is provided on the top of the substrate between the two guide holes. The limiting plate is connected to the first adjustment hole on the top of the substrate through a first adjustment screw.

[0007] Furthermore, a second adjustment hole is provided on the strip plate, and the second adjustment hole is connected to the substrate through a second adjustment screw.

[0008] Furthermore, the substrate has a transition plate at its edge away from the guide plate, which is integrally designed with the substrate and extends toward the sewing machine workbench.

[0009] Furthermore, a serpentine guide rod for guiding the fabric strip is installed at the inlet end of the guide plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When operating this utility model, the operation process is simplified, the labor intensity is reduced, and there is no need to manually align the fabric and strips. Simply embed them into the guide plate and guide hole respectively, pull them out and sew directly. Even beginners can quickly get started. The strips first pass through the serpentine guide rod before entering the guide hole, avoiding deviation or curling during straight feeding. The limit plate can be moved by loosening the first adjusting screw to adjust the width of the guide hole, so as to be suitable for use with strips of different widths, thus increasing the applicability range.

[0013] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1-3 As shown, this utility model provides an auxiliary positioning pull cylinder, including a mounting plate 1 and a base plate 2. A U-shaped guide plate 4 is fixedly connected to the top of the base plate 2 via a strip plate 3. A guide plate 5 with an L-shaped structure is provided at the bottom of the base plate 2. One side of the guide plate 5 is fixedly connected to one side of the base plate 2. The mounting plate 1 is fixed to the bottom of the guide plate 5. The mounting plate 1 is fixed to the worktable of the sewing machine by fastening screws 6. A strip-shaped mounting hole is provided on the mounting plate 1. The fastening screws 6 pass through the mounting hole to fix the pull cylinder to the worktable of the sewing machine. The strip-shaped mounting hole can adjust the installation distance between the pull cylinder and the sewing machine needle. Two parallel fabric strip guide holes 7 are provided on the guide plate 5. The fabric strip enters from one guide hole 7 and exits from the other guide hole 7.

[0015] like Figure 1 and Figure 3As shown, when sewing the fabric and strip together, first fix the mounting plate 1 to the sewing machine's worktable with the fastening screws 6, then place one side of the fabric inside the guide plate 4. The guide plate 4 is used to guide the fabric's movement, replacing manual positioning. The feed end of the strip enters through one guide hole 7 and exits through another guide hole 7, which can accurately guide the fabric's movement, forcing the strip to follow the preset path, while avoiding the strip's deviation or curling during straight feed. During operation, the fabric on both sides automatically aligns, and the worker does not need to manually position the fabric and strip. After pulling out the fabric and strip, they can be sewn directly, reducing the difficulty of the work and making it suitable for beginners or high-frequency operation.

[0016] A limiting plate 8 is installed between the guide plate 5 and the substrate 2. A first adjustment hole 9 is provided on the top of the substrate 2 and between the two guide holes 7. The limiting plate 8 is connected to the first adjustment hole 9 on the top of the substrate (2) through a first adjustment screw 10.

[0017] like Figure 2 and Figure 3 As shown, by loosening or tightening the first adjusting screw 10, the limiting plate 8 can move laterally or be fixed on the guide plate 5. The width of the two guide holes 7 can be adjusted by adjusting the limiting plate 8 so that it can accommodate strips of different widths of cloth.

[0018] The strip plate 3 has a second adjustment hole 11, and the second adjustment hole 11 is connected to the base plate 2 through a second adjustment screw 12.

[0019] like Figure 2 As shown, the installation position of the guide plate 4 can be adjusted by the second adjusting hole 11 and the second adjusting screw 12, thereby adjusting the distance between the fabric and the strip, indirectly controlling the relative position of the fabric and the strip, and precisely controlling the stitch distance.

[0020] The substrate 2 is provided with a transition plate 13 at the edge away from the guide plate 5, which is integrally designed with the substrate 2 and extends toward the sewing machine workbench.

[0021] like Figure 1 As shown, the transition plate 13 supports the base plate 2 on the sewing machine worktable, and the smooth transition plate 13 may reduce the resistance of the fabric passing through and reduce damage to the fabric.

[0022] The guide plate 5 is equipped with a serpentine guide rod 14 for guiding the fabric strip at its inlet end.

[0023] like Figure 1As shown, the serpentine guide rod 14 is fixedly installed at the inlet end of the guide plate 5 through the arc plate. The fabric strip can enter the guide hole 7 through the crossbar part of the serpentine guide rod 14 in sequence. It has the advantages of dynamic guidance, tension adjustment and path planning, and solves the drawbacks of traditional linear feed that is easy to deviate and difficult to control elastic fabric.

[0024] Operating principle: When in use, first fix the pull tube to the sewing machine worktable with the fastening screw 6. Then, adjust the position of the limiting plate 8 according to the width of the fabric strip and fix it with the first adjusting screw 9. According to the stitch distance between the fabric strip and the fabric, loosen the second adjusting screw 12 to adjust the installation position of the guide plate 4. Then tighten the second adjusting screw 12 to limit the guide plate 4. Embed one side of the fabric into the guide plate 4, which will forcefully constrain its direction. One end of the fabric strip enters into a guide hole 7 through the crossbar of the serpentine guide rod 14 and comes out from another guide hole 7. The worker does not need to manually align the fabric and the fabric strip. Just embed them into the guide plate 4 and the guide hole 7 respectively, pull them out and sew them directly through the sewing machine needle. Even beginners can quickly get started.

[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model.
