Abstract

The invention discloses an automatic presser foot device for a sewing machine. The automatic presser foot device comprises a rack, a sewing cutting template and a machine head, wherein the sewing cutting template is fixedly clamped on the rack, and the automatic presser foot device is arranged on the machine head; the automatic presser foot device comprises a presser foot motor fixed on the machine head; a motor shaft is fixed to the output end of the presser foot motor; a conveying wheel is fixed to the motor shaft; a conveying belt is arranged on the conveying wheel; a transmission base is fixedly connected to the conveying belt; a spring column and a needle column are arranged on the machine head in a penetrating mode; and the transmission base is fixedly connected with a presser foot column. The automatic presser foot device has the advantages that when the presser foot motor works, the motor shaft drives a transmission wheel to reciprocate at an angle, the transmission base enables the presser foot column and a sewing presser foot to be lifted, a first transmission belt is loosened when a downward pressing action is performed, a presser foot spring applies pressure to the presser foot column to enable the sewing presser foot to perform a downward pressing action quickly, and the height of lifting and downward pressing is determined by the rotation angle of the presser footmotor.

Description

technical field [0001] The invention relates to the technical field of garment manufacturing equipment, in particular to an automatic foot presser device for a lockstitch sewing machine. Background technique [0002] The function of the automatic device of the presser foot of the lockstitch sewing machine is in the garment manufacturing process. By cooperating with the movement of the sewing machine spindle, the sewing piece is used as a sewing tool for stable processing. If the sewing presser foot is abnormal, the sewing effect of the piece is likely to appear. Jumping wires, throwing wires, not connecting the wires, beading and other bad lines. [0003] In the prior art, the presser foot transmission device of manual lockstitch sewing machine is as figure 1 As shown, the device is mostly a manual part linked to the machine head through a connecting rod or a button to lift the presser foot. Every time the presser foot is lifted during work, a button operation is required b...
