Description

Technical Field

[0001] This utility model relates to the field of plush toy processing technology, specifically a fabric cutting machine. Background Technology

[0002] Plush toy manufacturing is the process of making plush toys from various materials through cutting, sewing, stuffing, and decorating. The process involves designing the toy's appearance based on market demand or customer requirements, making samples, confirming the design and process, selecting suitable plush fabric (commonly polyester fiber), laying out the fabric to reduce waste, using a fabric cutting machine or by hand, sewing the cut fabric into the toy shell, turning the sewn shell right side out, evenly stuffing the toy shell with PP cotton to ensure the toy's shape is full and uniform, sewing the stuffing opening with a hidden stitch, sewing or gluing eyes, noses, etc., adding ribbons, bows, etc., inspecting the stitching, stuffing, and accessories, removing loose threads and dust, and packaging with plastic bags or boxes.

[0003] In some existing fabric cutting machines, when cutting fabric, the fabric is wrapped around the outside of the unwinding roller, and then the fabric is manually pulled out to a certain length and pulled to the lower end of the cutting blade. Then, the cutting blade is driven by a motor to move downward to cut the fabric.

[0004] Existing fabric cutting machines of this type have the following problems: when cutting fabric, it is necessary to manually pull out the fabric and continue cutting the next piece of fabric, which is labor-intensive. At the same time, the cutting effect of a single cutting blade is not good and it is inconvenient to use. Therefore, we propose a fabric cutting machine. Utility Model Content

The rotation of the left gear 72 will drive the right meshing gear 72 to rotate. The rotation of the gear 72 will drive the rotating shaft 75 to rotate on the inner wall of the strip opening. Then, through the support of the rotating shaft 73, the support rod 74 will be driven to open and close in a scissor-like state. While the support rod 74 is swinging, it will drive the fixed column 78 to slide and rotate inside the sliding groove. When the fixed column 78 slides to the front end of the sliding groove, the fixed column 78 will drive the sliding plate 77 to move from the upper end of the slide plate 76 towards the center, which will drive the cutting blades 79 at both ends to cut the fabric.
