Sewing machine

The invention relates to a sewing machine which comprises a rack, a cloth hanging plate, a sewing machine head, at least one pair of cloth rolling wheels and at least one pair of cloth pull wheels. Both the sewing machine head and a cloth hanging plate drive mechanism are arranged on the rack. The cloth rolling wheels are elastically connected to a feeding opening of the sewing machine head in a sliding mode and are in longitudinal symmetry. The cloth pull wheels are elastically connected to a discharging opening of the sewing machine head in a sliding mode and are in longitudinal symmetry. The cloth hanging plate is connected with the cloth hanging plate drive mechanism in a transmission mode. The cloth hanging plate is driven by the cloth hanging plate drive mechanism to pass through the cloth rolling wheels from the feeding opening of the sewing machine head. The cloth pull wheels are close to the cloth hanging plate to clamp the cloth hanging plate and rotate to pull the cloth hanging plate away from the sewing machine head after sewing operation is conducted on cloth on the cloth hanging plate through the sewing machine head. The sewing machine has the advantages that the cloth hanging plate connected with cloth in a penetrated mode can be driven directly to move linearly and conduct feeding operation; compared with a fell seam machine, manual feeding is avoided, and the positions of the cloth hung on cloth hanging needles are relatively fixed; a water gap is controllable, sewing operation of the headmost end and the rearmost end of the cloth can be conducted effectively, and a reprocessing procedure is omitted.
