Background technique

Knitted fabrics are divided into two types: weft-knitted fabrics and warp-knitted fabrics according to the weaving method. Weft-knitted fabrics are often made of low-elastic polyester yarns or special-shaped polyester yarns, nylon yarns, cotton yarns, wool yarns, etc., and use flat stitches. Variable plain stitch, ribbed plain stitch, double rib plain stitch, jacquard stitch, terry stitch, etc. are woven on various weft knitting machines. During the processing of knitted fabrics, the fabrics need to be cut to meet the follow-up requirements. For the processing of fabrics, however, when the existing knitted fabric cutting machine is cutting knitted fabrics, it usually uses a fixing mechanism to fix the knitted fabric, but the fixing mechanism cannot be moved, which makes it inconvenient for the cutting machine to cut different sizes of fabrics.
