Background
At present, the single-side sewing device based on the curved needle and the rotating shuttle can be applied to the lock-stitch sewing device with a complex scene. The device utilizes a curved needle to lead, the curved needle penetrates into a fabric from one side of the fabric and penetrates out from the other position at the same side, then a rotating shuttle at the position hooks a thread ring on the curved needle, and after the rotating shuttle rotates for a circle, a thread is looped to lock a bottom thread in the rotating shuttle, thereby forming a lock stitch.
The existing lock stitch sewing device can only execute a certain item or a certain type of sewing work generally, and when the sewing scene is more complex or the sewing parameters of different parts on a product are inconsistent, different sewing devices are needed.
The unilateral lock stitch sewing device based on the curved needle utilizes the curved needle and the rotating shuttle to sew up, and when sewing up, the curved needle needs to take the suture to pierce into the cloth and then pierce out the cloth, and in this process, the suture needs continuous bending motion and friction. And the angle of the circular arc of the curved needle is larger, and in certain specific occasions, the curved needle can be bent and deformed and cannot be normally matched with the rotating shuttle in a movement way, so that higher requirements are provided for the rigidity of the curved needle. In addition, the inclination of the curved needle for penetration and penetration is too large, and the distance between a penetration point and a penetration point is large, so that the curved needle is not suitable for being used in a sewing scene with a relatively thick structure or a sewing needle with a nearly vertical penetration angle.
