Abstract

The invention relates to the technical field of sewing machines, in particular to a feeding-needle adjusting mechanism of a sewing machine. The needle feeding adjusting mechanism comprises a swinging shaft installed in a sewing machine head and a feeding needle installed at the lower end of the swinging shaft. The upper end of the swinging shaft is adjustably installed on a swinging crank, the swinging crank is connected with the lower end of a swinging plate through a swinging crank pin, and the upper end of the swinging plate is hinged to a needle-rod puncturing head of the sewing machine. The feeding-needle adjusting mechanism has the advantages that the needle feeding mechanism is effectively simplified, assembling time is saved, an upper cover does not need to be disassembled when a feeding-needle journey is adjusted, and meanwhile it is guaranteed that the feeding needle and a machine needle of the sewing machine are synchronous.

Description

technical field [0001] The invention relates to the technical field of sewing machines, in particular to a needle feeding adjustment structure of the sewing machine. Background technique [0002] The needle feeding adjustment structure of the existing sewing machine includes a crank linkage mechanism driven by the sewing machine main shaft, the crank linkage mechanism further drives the swing shaft to work, and the swing shaft drives the needle feed to swing. The specific working principle of this structure is: the main shaft rotates counterclockwise to drive the eccentric sleeve to rotate, the eccentric sleeve rotates and drives the needle feeding swing crank to swing through the needle feeding connecting rod, the swing crank drives the swing connecting rod shaft to swing, and the swing connecting rod shaft swings to drive The needle feeding swing connecting rod swings, and finally the needle feeding swing connecting rod drives the needle feeding to swing through the swing ...
