Double-needle type sewing machine

Abstract

The invention relates to a double-needle type sewing machine. The double-needle type sewing machine comprises a base, a through hole is formed in the base, miniature air cylinders are fixedly connected inside the through hole, a supporting plate is fixedly connected to the output ends of the miniature air cylinders, a sewing machine body is fixedly connected to the top of the base, an anti-windingassembly is arranged on the sewing machine body and comprises an installing base, connecting plates and a drive shaft, the installing base is fixedly connected to the front side face of the sewing machine body, the connecting plates are fixedly connected to the front side face of the installing base, the drive shaft is movably connected between the connecting plates, a needle bed is fixedly connected to the bottom of the sewing machine body, a threaded groove is formed in the bottom of the needle bed, a connecting base is movably connected inside the threaded groove, and a sewing needle is fixedly connected to the bottom of the connecting base. The double-needle type sewing machine is reasonable in structure, can adjust the distance between double needles and the distance between the needles and the base, meets the demands of different clothes, and is higher in practicability.

Description

technical field [0001] The invention relates to a double-needle sewing machine, which belongs to the technical field of sewing machines. Background technique [0002] Double-needle sewing machine (also called double-needle flat car) is a commonly used sewing machine with two needles, two synchronous, three synchronous, and corner sewing. Yes, although the flat car can sometimes replace the double needle, considering the efficiency, use the flat car to do the work of the double needle in mass production, unless it is a small amount of production, the efficiency of the double needle is high, and the double lines are parallel and neat, but the existing double needle type The sewing machine is prone to thread entanglement, and because the height and distance of the double needles cannot be adjusted, it cannot meet the needs of different fabrics. Contents of the invention [0003] The technical problem to be solved by the present invention overcomes the existing defects, and p...

[0002] Double-needle sewing machine (also called double-needle flat car) is a commonly used sewing machine with two needles, two synchronous, three synchronous, and corner sewing. The effect is that the double threads are side by side and parallel to each other, but it is essential Yes, although the flat car can sometimes replace the double needle, considering the efficiency, use the flat car to do the work of the double needle in mass production, unless it is a small amount of production, the efficiency of the double needle is high, and the double lines are parallel and neat, but the existing double needle type The sewing machine is prone to thread entanglement, and because the height and distance of the double needles cannot be adjusted, it cannot meet the needs of different fabrics
