[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example

[0026] Reference Figures 1-4 A sewing device for a shirt placket tube-pulling process includes a processing table 1, a presser foot 16, and a sewing needle 17. The sewing device also includes:

[0027] Pulling cylinder 2, which is fixedly installed on the top of the processing table 1;

[0028] A limiting component is provided on the top of the processing table 1 and is used for limiting the conveyance of the shirt placket;

[0029] The positioning assembly includes: a U-shaped frame 11, a screw 12, a movable frame 13 and a pressure roller 14. Both ends of the bottom of the U-shaped frame 11 are fixedly mounted on the top of the processing table 1. The bottom end of the screw 12 passes through the top of the U-shaped frame 11 and is threadedly connected to the U-shaped frame 11. The top of the movable frame 13 is rotatably connected to the bottom end of the screw 12. The front and rear ends of the pressure roller 14 are rotatably connected to the front inner wall and the rear inner wall of the movable frame 13 respectively.

[0030] By means of the above structure: by rotating the screw 12 and through the threaded connection between the screw 12 and the U-shaped frame 11, the movable frame 13 and the pressure roller 14 can be driven to move downward and the shirt placket can be pressed down to limit the position, which can avoid the shirt placket from warping during transportation and ensure that the presser foot 16 and the sewing needle 17 can sew the shirt placket stably.

[0031] As a preferred solution of the present invention, the limiting assembly includes an L-shaped bracket 3, two vertical rods 4, two sliders 6, a movable roller 7 and a fixed roller 9. The bottom end of the L-shaped bracket 3 is fixedly mounted on the top of the processing table 1, and the top ends of the two vertical rods 4 are fixedly mounted on the bottom of the L-shaped bracket 3. Sliding holes 5 are opened on the two vertical rods 4, and the sliders 6 are slidably connected in the corresponding sliding holes 5. The ends of the two sliders 6 that are close to each other are rotatably connected to the same movable roller 7. The front and rear ends of the fixed roller 9 are respectively rotatably connected to the sides of the two vertical rods 4 that are close to each other. The fixed roller 9 cooperates with the movable roller 7. By setting the limiting assembly and supporting the sliding of the movable roller 7 by the slider 6, the limited transportation of the shirt placket can be achieved through the cooperation of the fixed roller 9, ensuring that the shirt placket is spread out during transportation after being formed by the pull tube 2, thereby improving the sewing efficiency of the shirt placket.

[0032] As a preferred solution of the present invention, springs 8 are fixedly installed on the top inner walls of the two sliding holes 5, and the bottom ends of the springs 8 are fixedly installed on the tops of the corresponding sliders 6. By setting the springs 8, the sliders 6 and the movable rollers 7 can be driven to move downward and reset.

[0033] As a preferred solution of the present invention, a guide plate 10 is fixedly installed on the top of the processing table 1, and the shirt placket can be guided and transported by providing the guide plate 10.

[0034] As a preferred solution of the present invention, two stabilizing bars 15 are fixedly installed on the top of the movable frame 13. The top ends of the two stabilizing bars 15 pass through the top inner wall of the U-shaped frame 11 and extend to the top of the U-shaped frame 11. By setting the stabilizing bars 15, the up and down movement stability of the movable frame 13 and the pressure roller 14 can be improved.

[0035] As a preferred solution of the present invention, an adapting groove 18 is provided on the top of the processing table 1, and the adapting groove 18 can facilitate the downward movement of the sewing needle 17 for sewing.

[0036] The working principle of the present utility model is as follows: when in use, the shirt placket is first passed through the inside of the pull tube 2, and then the shirt placket is formed and passed between the movable roller 7 and the fixed roller 9. At this time, the elastic force of the spring 8 and the sliding block 6 support the movable roller 7, and then the fixed roller 9 cooperates to realize the limited conveyance of the shirt placket, ensuring that the shirt placket is spread out during conveyance after being formed by the pull tube 2, thereby improving the sewing efficiency of the shirt placket. At this time, the shirt placket is guided by the guide plate 10 and passes under the pressing roller 14. Here, by rotating the screw 12 and through the threaded connection between the screw 12 and the U-shaped frame 11, the movable frame 13 and the pressing roller 14 can be driven to move downward and the shirt placket can be pressed downward to limit the position, which can avoid the situation of warping of the shirt placket during conveyance and ensure that the presser foot 16 and the sewing needle 17 can sew the shirt placket stably.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
