Press foot special for sewing parachute connection rope and sewing machine

Abstract

The invention discloses a press foot special for sewing a parachute connection rope. The press foot includes a compressing rod (1) and a groove pressing block (2), wherein the compressing rod (1) includes a vertical part and a bent part, the vertical part is of a rectangular flat structure, the upper end of the bent part is connected with the bottom end of the vertical part, the top end of the groove pressing block (2) is connected with the bottom end of the bent part of the compressing rod (1), rectangular positioning grooves of which the lengths are the same as the length of the groove pressing block (2) are formed in the bottom of the groove pressing block (2), and the rectangular positioning grooves are clamped in the two sides of the parachute connection rope, so that the parachute connection rope is limited in the rectangular positioning grooves of the groove pressing block (2). The invention further discloses a sewing machine with the special press foot. The special press foot has good positioning effects, the difficult problem of buckling is solved, and the difficult problems are solved that when sewing materials are relatively thick or round, the press foot does not easily compress the sewing materials, and upper and lower parts of a sewing part are misplaced.

Description

technical field [0001] The invention belongs to the technical field of sewing machines, and more specifically relates to a special presser foot for sewing parachute connecting ropes and a sewing machine. Background technique [0002] Sewing machines for sewing can be roughly divided into two types: industrial and household. The sewing machine is mainly composed of four parts: the machine head, the machine base, the transmission and the presser foot. It is a machine that forms one or more stitches on the cloth to interweave or sew the cloth. Parachute products used in aerospace and sewing machine equipment are also used for sewing. Among them, the function of the sewing machine presser foot is to press the cloth against the feed dog so that the cloth can move when sewing. [0003] Generally, the sewing part requires the sewing part of the object to be sewn to advance according to a certain trajectory, and the sewing thread is required to be straight and uniform, and the thr...
