The invention discloses an integrated mechanism for rough edge trimming and sundry removal during high-speed fabric sewing. The mechanism comprises a pressing foot sewing mechanism and a gas tube sundry removal mechanism, wherein the gas tube sundry removal mechanism is disposed on a sewing mechanism and located at a feeding hole of the pressing foot sewing mechanism; the pressing foot sewing mechanism comprises a fabric placement groove; the fabric placement groove has a U-shaped structure, and an opening of the groove faces a material operation platform of the sewing mechanism; the fabric placement groove has a structure of which the width decreases gradually from top to bottom; and the gas tube sundry removal mechanism comprises a gas tube. A fabric to be processed by the rough edge trimming is placed in the fabric placement groove for sewing; and an operation worker only needs to adjust the quantity of the fabric placed into the fabric placement groove at earlier stage.
