The invention provides an automatic pulling and hot-cutting machine. The machine comprises a discharge mechanism, a hot-cutting mechanism and a pulling mechanism in sequence according to the fabric moving sequence, wherein the discharge mechanism comprises a discharge frame, a cloth guide roller, a feed frame, feed rollers and a fixing clamp; the hot-cutting mechanism comprises a hot-cutting cylinder, a heating wire support and a heating wire; the pulling mechanism comprises a pulling workbench, a pulling motor, a pulling guide rail, a pulling frame, a moving clamp and a moving clamp cylinder. The machine can be applied to fabrics with different materials and widths, and practicability is strong; automation of pulling and hot-cutting is realized, and consumption of human resources is greatly reduced; the problem of uneven cuts due to uneven tension during hot cutting of the fabrics is effectively solved; meanwhile, the cuts are free of raw and rough edges.
