[0003] Most of the cloth products we use require sewing, but most of the sewing equipment in the current production environment

[0004] There is no feeding device, so a feeding device designed for sewing machines is particularly important for improving production efficiency.

[0005] is important.

[0006] For example, Chinese patent publication number CN220012985U discloses a sewing machine feeding mechanism, which relates to the technical field of sewing machines and includes a supporting bottom groove plate, a driving mechanism provided above the supporting bottom groove plate, a push plate provided above the driving mechanism, a threaded long rod rotatably connected to the left side of the push plate, a frame plate threadedly connected to the outer surface of the threaded long rod, a bottom surface of the frame plate fixedly connected to the upper surface of the supporting bottom groove plate, a rotating hand-held slot fixedly connected to the outer surface of the threaded long rod, and a sewing machine body mounted on the upper surface of the supporting bottom groove plate. The rotating hand-held slot can be rotated to drive the threaded long rod to rotate, thereby driving the pushing plate to move, thereby moving the fabric on the driving mechanism, improving the convenience of moving the fabric to the sewing position, and improving the efficiency of the device in sewing fabric. Activating the provided cylinder can drive the clamping slot and the driving frame to move, thereby driving the unloading plate to slide on the longitudinal limit strip. Although this type of sewing machine feeding mechanism can improve the convenience when the sewing position cannot be moved by using a driving mechanism and various moving mechanisms, the sewing machine feeding mechanism of this solution cannot keep the fabric in a stretched state when fixing the fabric, which may affect product quality.
