The device comprises a vertical plate, a fixing plate is fixedly connected to the right end of the vertical plate, and an electricpush rod is fixedly installed on the fixing plate; a retractable rod is installed on the electric push rod, a pressure foot plate is fixedly connected to the bottom of the retractable rod, and a working plate is fixedly connected to the right end of the pressure foot plate; a rectangular through hole is formed in the working plate, pressure foot idler wheels are movably connected to the bottom ofthe pressure foot plate through rotation shafts, and a connection rod is fixedly connected to the left end of the pressure foot plate; a slide block is fixedly connected to the left end of the connection rod, a slide groove is formed in the right end face of the vertical plate, and a first supporting plate is fixedly connected to the bottom of the vertical plate; second supporting plates are fixedly connected to the two ends of the first supporting plate respectively, mounting bases are fixedly connected to the bottoms of the second supporting plates, and a control switch is further arrangedon the vertical plate and connected with the electric push rod through a wire. The whole device is convenient to use, cloth is conveniently pressed and conveyed, and the working efficiency of the sewing machine is improved.

Description

technical field

[0001] The invention relates to a sewing machine presser foot device, which belongs to the field of sewing equipment. Background technique

[0002] A sewing machine is a machine that uses sewing thread to sew one or more layers of sewing materials together. The sewing machine can sew fabrics such as cotton, linen, silk, wool, and artificial fibers and products such as leather, plastic, and paper. Neat and beautiful, flat and firm, fast sewing speed and easy to use. And derived art forms such as hand-push embroidery and computer embroidery. There are many classification methods of sewing machines. The more common ones are distinguished by stitches and uses. Type stitch is the most common. It consists of two sutures, which are intertwined like twisted ropes. The interweaving point is in the middle of the sewing material. From the cross-section of the stitches, the two sutures are like two locks interlocking each other. Therefore, it is called a lock stitch, w...
