Abstract

The invention provides a pressure foot lifting and inverted material feeding device of a sewing machine, belonging to the mechanical technical field. The pressure foot lifting and inverted material feeding device solves the technical problems of complex structure, high producing cost and the like existing in the existing sewing machine. The pressure foot lifting and inverted material feeding device of the sewing machine is arranged on a baseboard of the sewing machine and comprises a control mechanism, a power part and a clutch mechanism which are connected with the baseboard of the sewing machine, wherein the clutch mechanism has two power output ends; the control mechanism is connected with the clutch mechanism; the control mechanism can cause one of the power output ends to be connected with the power section; one of the power output ends is connected with an inverted material feeding mechanism of the sewing machine, and the other power output end is connected with a pressure foot lifting mechanism of the sewing machine. The device has compact structure, beautiful appearance, simple structure design, and reduces the cost of the sewing machine.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a sewing machine, in particular to a presser foot lifting and reverse feeding device of the sewing machine. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. The sewing machine can sew fabrics such as cotton, fiber crops, silk, wool, and artificial fibers, and products such as leather, plastics, and paper. [0003] Existing sewing machines such as Figure 4 As shown, there are presser foot lifting and reverse feeding mechanisms independent of each other on the sewing machine. And the power part of the presser foot lifting mechanism is located outside the sewing machine casing; the power part of the reverse feeding mechanism is located at the bottom plate of the sewing machine. [0004] In the sewing machine with the above...
