[0085] In the present technical solution, the sewing section 400 is composed of a fully automatic sewing machine 410 and a second moving section 420. The fully automatic sewing machine 410 is placed on a workbench 100 and connected to a data processing center via a communication line. When the fixed section 600 moves the textile cloth to the sewing section 400, the data processing center 140 commands the automatic sewing machine to operate and sew, which effectively reduces the workload of workers and improves work efficiency.

[0086] The second moving part 420 is composed of a connecting rod, a sliding block 422, a third screw rod 424, a first servo motor 423 and a protective cover 430, and a moving groove 150 specifically for the second moving part 420 to move is provided on the workbench 100, the connecting column 421 is detachably connected to the full-automatic sewing machine 410, and the connecting column 421 is connected to the sliding block 422. By moving the sliding block 422, the connecting column 421 can be moved in the moving groove 150, and the connecting column 421 then moves the full-automatic sewing machine 410.

[0087] In order to more accurately realize the position movement of the fully automatic sewing machine 410, a third screw rod 424 is further provided in the sewing part 400, and a threaded hole matching the third screw rod 424 is provided on the sliding block 422, and the third screw rod 424 is threadedly connected to the sliding block 422, and a first servo motor 423 is further provided at the other end of the third screw rod 424 relative to the sliding block 422, and the first servo motor 423 is connected to the screw rod through a coupling, and the first servo motor 423 is connected to the data processing center 140 through a communication line. When the sewing machine 410 moves, the signal from the data processing center 140 can drive the servo motor to rotate and then drive the screw to move the sliding block 422. The precise calculation of the data processing center 140 and the output of the servo motor can achieve precise control of the position of the full-automatic sewing machine 410, thereby improving the working accuracy of the present technical solution. The position of the full-automatic sewing machine 410 in the present design solution can be changed through the design of the second moving part 420. The present technical solution can complete more products of different sizes, thereby increasing the diversity of products that can be achieved by the present technical solution.

[0088] In the present technical solution, the sewing part 400 is also provided with a protective cover 430, and the third screw rod 424 and the sliding block 422 are placed in the protective cover 430, wherein the screw rod and the protective cover 430 are rotatably connected, and the protective cover 430 is in the form of a rectangular parallelepiped, and the upper and right sides of the protective cover 430 are openings, and the upper side of the protective cover 430 is detachably connected to the workbench 100 by bolts. The protective cover 430 can effectively prevent the moving part from being stuck by foreign objects or accidentally touched by workers during operation, thereby increasing the stability and safety of the present technical solution.
