Embodiment Construction

[0044] Below in conjunction with accompanying drawing, the shuttle swing mechanism of the novel sewing machine and the needle bar stabbing material and its combined mode are illustrated.

[0045] refer to figure 2 , image 3 Structure and mechanism transmission of the present invention are further described as follows:

[0046] The stabbing and hooking combination device of the sewing machine includes a shuttle hooking mechanism and a stabbing mechanism; it is characterized in that:

[0047] The crank assembly A includes a vertical shaft 1, a hook crank 2, a long connecting rod 4, a sector gear 7, a pinion 8, an upper shaft gear 58, and a vertical shaft gear 59. Wherein the upper shaft gear 58 and the vertical shaft gear 59 keep meshing, the upper end of the vertical shaft 1 is fixed on the vertical shaft gear 59 via a screw 57, and the lower end of the vertical shaft 1 is fixed in the center hole on the upper part of the hook crank 2 via a screw 3; One end of the long con...

Abstract

The invention discloses a needle bar and a thread hooking combination device of the sewing machine, comprising a swing shuttle swinging mechanism and a needle bar mechanism. The swing shuttle swinging mechanism is composed of a thread hooking crank component A and a pendulum shaft component B; the needle bar mechanism is composed of a needle bar cam assembly unit A and a swing rod assembly unit B; wherein, the thread hooking crank component A comprises a vertical shaft, a thread hooking crank, a long connecting rod, a pinion, an upper shaft gear and a vertical shaft gear; the pendulum shaft component B comprises an installing seat and a pendulum shaft strung inside the central seat sleeve of the installing seat; the needle bar cam assembly unit A is composed of an upper shaft connected with a driving device of the host machine of the sewing machine and a needle bar cam nested on the shaft rod; and the swing rod assembly unit B is composed of a needle bar, a swing rod and a fixing pedestal. The swing shuttle swinging mechanism and the cam swing rod slider needle bar mechanism of the sewing machine are matched with each other to move by means of the rotation of the upper shaft, thereby forming a novel thread hooking combination mechanism of the swing shuttle sewing machine needle bar.

Description

technical field [0001] The invention relates to a stitching material and thread hook combination device of a sewing machine, which belongs to the category of sewing machine components. Background technique [0002] The shuttle shaft of the traditional shuttle sewing machine is placed horizontally, and the movement mode is to swing around the axis. The transmission mode of the mechanism adopts a crank rocker mechanism and a guide rod mechanism connected in series. The transmission mode of the thrusting mechanism adopts the crank slider mechanism. The combination of the above-mentioned swinging movement mechanism of the shuttle shuttle and the stabbing mechanism of the crank slider forms a combination mechanism of the stabbing and thread hooking of the traditional shuttle sewing machine. [0003] The swing structure of the traditional sewing machine shuttle is as follows: figure 1 shown. The connection structure of the swing mechanism of the shuttle hook line is: the long ...
