Sewing machine needle bar separation mechanism

Abstract

The invention discloses a needle bar separation mechanism of a sewing machine, and belongs to the technical field of manufacturing of sewing machines. The needle bar separation mechanism of the sewing machine resolves the technical problem that in the prior art, a puncturing mechanism and a feeding mechanism of the sewing machine can not be separated. The needle bar separation mechanism of the sewing machine comprises a machine head shell (1), wherein an upper shaft is arranged on the machine head shell (1) in the axial direction and is divided into two sections, namely an upper shaft I (2) and an upper shaft II (3), a clutch device used for achieving separation and combination of the two upper shafts is arranged at the two opposite ends of the upper shaft I (2) and the upper shaft II (3), and the clutch device comprises a swinging component driven by a driving device. Due to the fact that the clutch device is arranged, combination and separation of the upper shaft I (2) and the upper shaft II (3) are achieved, the puncturing mechanism and the feeding mechanism can be combined with and separated from each other, continuous jump line sections can be formed on cloth, various sewing requirements are met, a clothing material is more beautiful, and work efficiency and product quality are improved.

Description

technical field [0001] The invention belongs to the technical field of sewing machine manufacturing, and in particular relates to a sewing machine needle bar separation mechanism capable of realizing the combination and separation of the main shaft of the sewing machine and the main shaft of the stabbing mechanism. Background technique [0002] Traditional sewing machine generally all comprises support, and head housing is set on support, and main shaft, thread take-up mechanism, stabbing material mechanism, feeding mechanism and thread hook mechanism are set in the head housing. During the working process, the main shaft drives the thread take-up mechanism, stabbing mechanism, feeding mechanism and thread hooking mechanism to realize synchronous movement, and the stabbing mechanism is driven by the main shaft to perform stabbing movement, so that the upper thread punctures through the fabric, and the main shaft drives the feeding mechanism to feed The movement makes the clo...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to eliminate the technical problem that the stabbing mechanism and the feeding mechanism of the sewing machine cannot be separated in the prior art, and to provide a sewing machine with the ability to separate and combine the stabbing mechanism and the feeding mechanism, so as to sew out the thread on the cloth. Trace segment and jumper segment, to avoid manual removal of stitches by workers, improve work efficiency
