[0020] like Figures 1 to 3As shown, this utility model discloses a guiding and correcting mechanism, including a guiding and correcting wheel. The guiding and correcting mechanism is positioned above the worktable to correct misaligned material and move it to the sewing machine needle for sewing. It has a simple structure, is easy to install, and optimizes sewing results.

[0021] like Figure 4 and Figure 5 As shown, the guide wheel includes an independently rotatable feeding roller 1. One end of the feeding roller 1 has multiple mounting slots 1a evenly formed along its circumference for mounting the correction gears 2. The correction gears 2 are rotatably mounted within the mounting slots 1a. An independently rotatable main shaft 3 is located inside the feeding roller 1, and the main shaft 3 is rotatably mounted within the feeding roller 1 via a first bearing 12. One end of the main shaft 3 has a threaded rod 4, the surface of which is formed with threads 4a that mesh with the correction gears 2. The other end of the main shaft 3 is connected to a correction motor 5.

[0022] The feeding roller 1 is rotatably mounted on the first lifting seat 7. The correction motor 5 is fixedly mounted on the first lifting seat 7 via the correction motor mounting plate 6. The drive shaft of the correction motor 5 is connected to the main shaft 3. The correction motor 5 can drive the threaded rod 4 to rotate. The correction gear 2 meshes with the threaded rod 4, thereby driving the correction gear 2 to rotate back and forth. The correction gear 2 contacts the material and corrects the material's position deviation.

[0023] The feeding roller 1 is connected to a feeding motor 8 via a feeding transmission assembly. The feeding motor 8 is fixedly mounted on the first lifting seat 7 via a feeding motor mounting plate 9. The feeding transmission assembly includes a first driving wheel 10, a first driven wheel, and a first synchronous belt 11. The drive shaft of the feeding motor 8 is rotatably connected to the first driving wheel 10. The feeding roller 1 has a first driven wheel on its outer side, and the first synchronous belt 11 is sleeved on the first driving wheel 10 and the first driven wheel. The feeding motor 8 can drive the feeding roller 1 to rotate, and the correction gear 2 at the front end of the feeding roller 1 assists in moving the material to the sewing mechanism.

[0024] The first lifting seat 7 is slidably mounted on the first mounting base 14 via the first slide rail 13. The first mounting base 14 is provided with a vertically arranged first lifting cylinder 15. The drive rod of the first lifting cylinder 15 is connected to the first lifting seat 7, and the first lifting cylinder 15 can drive the first lifting seat 7 to move up and down. The upper end of the first lifting cylinder 15 is provided with an adjustable screw 16, which is located above the first mounting base 14. When the first lifting cylinder 15 drives the first lifting seat 7 to move downward, the lower end of the adjustable screw 16 moves downward and abuts against the upper end of the first mounting base 14, and the first lifting seat 7 stops moving. By adjusting the position of the adjustable screw 16 on the first lifting seat 7, the lifting height of the first lifting seat 7 can be limited.

[0025] The front end of the first mounting base plate 14 is provided with a material support plate 17. The upper surface of the material support plate 17 is formed with an arc-shaped groove 17a that conforms to the curvature of the guide wheel. The arc-shaped groove 17a corresponds vertically to the guide wheel. The first lifting cylinder 15 drives the first lifting seat 7 to move downward. The guide wheel moves downward with the first lifting seat 7 and comes closer to the material on the material support plate 17. The material moves along the arc-shaped groove 17a, increasing the contact area between the material and the guide wheel, which facilitates correction and feeding.

[0026] The first lifting seat 7 is equipped with a reverse bone joint mechanism, which includes an elastic reverse bone plate 18 that can move up and down. The elastic reverse bone plate 18 is connected to a reverse bone cylinder 19, which is mounted on a reverse bone cylinder mounting bracket 20. The reverse bone cylinder mounting bracket 20 is connected to the first lifting seat 7 through a feeding motor mounting plate 9.

[0027] The front end of the first lifting seat 7 is provided with a first guide plate 21 and a second guide plate 22. The inner side of the first guide plate 21 has a first groove 21a for the elastic reinforcing piece 18 to pass through. The elastic reinforcing piece 18 can pass through the first guide plate 21 and the second guide plate 22 along the first groove 21a. The lower ends of the first guide plate 21 and the second guide plate 22 have arc-shaped curved surfaces. The output end of the material support plate 17 has an extended inclined surface 17b, which corresponds vertically to the elastic reinforcing piece 18. An air blowing pipe 23 is provided on one side of the feeding motor mounting plate 9, and the outlet end of the air blowing pipe 23 faces the inclined surface 17b.

[0028] When the material's suture passes through the inclined plane 17b, the air blowing pipe 23 blows compressed air toward the material's suture. Subsequently, the reverse suture cylinder 19 drives the elastic reverse suture plate 18 to pass through the first guide plate 21 and the second guide plate 22 along the first groove 21a. The elastic reverse suture plate 18 contacts the inclined plane 17b, and the front end of the elastic reverse suture plate 18 folds the material's suture in the same direction.

[0029] The preferred embodiment of this utility model has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of this utility model.
