[0002] Blankets are a common bedding product that provides warmth and is thinner than quilts. They are often made from animal fibers (such as wool, mohair, rabbit hair, cashmere, camel hair, and yak hair) or chemical fibers like acrylic and viscose. Some are blends of animal and chemical fibers. Embossing machines are primarily used for embossing, foaming, wrinkling, and branding on various fabrics. They can also be used to emboss non-woven fabrics, coatings, artificial leather, paper, and aluminum sheets, imitating leather patterns and various shades of patterns. Custom blankets require cutting.

[0003] The prior art can refer to the Chinese patent with the authorization publication number CN107099993A, which discloses a blanket cutting device, including a workbench, movable devices welded on both sides of the workbench, and each movable device includes a guide rail, a sliding support frame is clamped at the upper end of the guide rail, and a slot is opened at the bottom end of the sliding support frame, and a protective pad is clamped in the slot, and a carpet is placed on the protective pad. However, this cutting device still has some shortcomings when used:

[0004] First, the blanket cannot be fixed according to its size, which may cause the blanket to be loosely fixed and cause deviation in the cut size;

[0005] Secondly, the blanket may curl or wrinkle due to the influence of wind during cutting, which may cause the cutting position to be inaccurate and make the blanket inconvenient to use after production.

[0006] Therefore, a positioning structure for cutting a blanket is provided. Utility Model Content
