The pull-down vertical driving member is used to drive the pull-down horizontal driving member and the pull-down rod to move vertically up and down, and the pull-down horizontal driving member is used to drive the pull-down rod to extend and retract horizontally. The pull-down rod can pass through the material unloading space and make the material in the material unloading space form a U-shaped hanging state; the sewing device sews the material, and the material after sewed is an annular structure; the material fixing mechanism also includes a material fixing portion, which includes two material fixing parts, and a spacing space for the pull-down rod to pass through is provided between the two material fixing parts.
