[0002] Existing sewing machines are all standard sewing machines, which can only perform basic sewing work. In the process of fabric processing, it is often necessary to manually perform other processes on the fabric. When processing the trouser ears, the trouser ear fabric must be folded in half, sewn according to the seam position with a flat machine, and then the seam position is ironed with an iron. Then, the trouser ears are turned out along the seam position with a thin iron wire, and finally ironed again. Such a complicated processing process requires several people to work together to complete, which seriously affects work efficiency.

[0003] The prior art CN201620921200.5 discloses a trouser loop sewing device without visible stitches and a sewing machine, comprising a fixing part, a sewing part, a workbench, a sewing machine head and a foot pedal, wherein the fixing part is arranged on the workbench, the sewing part is fixedly connected to the fixing part, the sewing part is located below the sewing machine head, and the sewing part comprises a feeding section, a pull tube for folding the cloth strips, a sewing hole and a discharging section. Although the utility model can automatically fold and shape the trouser loops, the following problems still exist:

[0004] 1. In high-end clothing, the requirements for trouser loops are higher. The edges of the folded and sewn trouser loops need to be opened to both sides respectively to ensure that the trouser loops are flat after ironing. However, the utility model directly flips and irons the trouser loops after sewing, causing the two folded edges to lean to one side, resulting in one side of the trouser loops being thicker and the other side being thinner, affecting product quality.

[0005] 2. During the automatic folding and sewing process, how to ensure the accuracy and consistency of each stitch is a major challenge, especially under high-speed operation, which may face problems such as skipped stitches and uneven stitches, requiring more sophisticated tension adjustment and sewing speed control mechanisms.

[0041] The working principle and use method of a trouser loop center splitting forming device of this embodiment:

[0042] The present embodiment provides a trouser loop center-split forming device, in which a fixing plate 1 is set on a sewing machine 5 by means of a fixing groove 11 and a nut to ensure the stability of the device. The guide forming device 2 then folds the fabric precisely in half and sews it through the sewing hole 21 below the sewing needle 51 to form a preliminary trouser loop structure. After the sew- ing is completed, the V-shaped end of the center-split rod 41 will gently contact and guide the sewing edges to separate to both sides, so that the edges of the fabric are separated to both sides, and then enter the inside of the flip pull tube 3 to flip the sewn trouser loops inside, ensuring that the edges of the trouser loops on both sides are flat and symmetrical after flipping, thus creating good conditions for subsequent ironing.

[0043] When in use, first, ensure that the sewing machine 5 is in the stopped state, then align the fixing plate 1 with the corresponding position on the sewing machine 5 through the fixing groove 11 thereon, use the nut to tighten the fixing plate 1, ensure that the sewing hole 21 of the guide molding device 2 is accurately aligned with the needle position of the sewing machine 5, then stuff the fabric for making the trouser loops into the guide molding device 2, and ensure that the fabric is flat and the folding line is aligned with the center of the guide molding device 2, and then transfer it back from the flip pull tube 3 to the entrance end of the guide molding device 2, and then start the sewing machine 5. The fabric will automatically fold into the shape of trouser loops under the action of the guide molding device 2, and be sewn through the sewing holes 21 on the device. The operator needs to control the sewing speed to ensure that the sewing stitches are even and firm to form a preliminary trouser loop. Loop structure, once the trouser loops are sewn, the V-shaped end of the center dividing rod 41 will lightly touch the sewn edge before turning over, guiding and prompting the fabrics on both sides of the sewn part to separate naturally, so that they are respectively biased towards the two sides of the trouser loops.
