Embodiment 1

[0024] A sewing machine threader such as Figure 1-3 As shown, the fixed seat 1 is included, and the threader main body 2 is arranged on the fixed seat 1 with the fixed seat 1 as a reference. The fixed seat 1 is set as a "Z" shape, and is divided into a fixed plate body for fixing on an external sewing machine, and a connecting plate body perpendicular to the fixed plate body. The part is connected to the main body 2 of the threader through a rotating pair. The rotating pair in this embodiment uses a plug screw as a connecting piece, which runs through the side of the main body 2 of the threader and the bent edge of the fixing seat 1. Tighten the hexagonal nut at the end as a fastener, so that the main body 2 of the threader can be set in rotation with the fixed base 1 as the movement reference.

[0025] like image 3 As shown, the angle range of the threader body 2 rotating around the rotary pair is 0-90°, and the initial position of the threader body 2 is the position perp...

Embodiment 2

[0032] An industrial sewing machine, which is applied with the sewing machine threader of Embodiment 1, wherein a triangular support is set at the turning point of the fixing seat 1 of the sewing machine threader as a rib plate, so as to reduce the shaking caused by the rotation of the threader main body 2 and enhance the stability of the threader sex; such as Figure 4 As shown, the fixed plate body of the fixed seat 1 is used as one end of the connection, and is connected to the end of the presser foot bar 8 of the lockstitch sewing machine.

[0033] When the sewing machine was not broken, the threader main body 2 was in an open state, that is, the threader main body 2 was perpendicular to the connecting plate body of the holder 1, and the U-shaped guard finger 6 on the threader was used to block the fingers. In order to prevent the sewing machine operator from putting his finger under the sewing machine needle by mistake during operation. What threader main body 2 played t...

Abstract

The invention discloses a sewing machine threader and an industrial sewing machine applying the same. Based on the principles of spring elastic deformation and magnetism and aiming at the requirementfor automatic threading at a high-strength eye use state in sewing production, the developed industrial sewing machine threader serves as an independent part and can be selectively assembled with theindustrial sewing machine; and the developed industrial sewing machine threader is conductive to reducing eye fatigue of workers, meanwhile, the threading action accuracy is improved, and the labor hour cost is saved. According to the technical scheme, the industrial sewing machine threader comprises a fixing base, a threader main body is rotationally connected to the fixing base, an included angle is formed between the initial position of the threader main body and the fixing base, a space formed by the included angle is used for containing a sewing machine needle, limiting between the threader main body and the fixing base is achieved through magnetic attraction, and a movably stretchable crochet hook for threading is arranged on the threader main body.

Description

technical field [0001] The invention belongs to the field of textile and garment machinery, and relates to an industrial sewing machine threader based on spring elastic deformation and magnetic principles. Background technique [0002] At present, in the textile and garment industry, there are many types of industrial sewing machines, including lockstitch sewing machines, chain sewing machines, overlock sewing machines, interlock sewing machines, herringbone cars, keyhole machines and tacking machines, among which the most common The model is an industrial sewing machine. The main mechanisms of industrial sewing machines include thread take-up mechanism, feeding mechanism, thread hooking mechanism and needle bar mechanism, etc. These mechanisms have basically reached the level of automation, yet the link of threading is still completed by manual threading by sewing workers. Existing auxiliary sewing machine threading tools are mostly replaced by crochet needles with strong...
