Problems solved by technology

[0004] However, the method in the above-mentioned prior art can solve the problem of skipped stitches, but it needs to install additional air blowing devices and air pressure equipment on the sewing machine, and it will be different due to the difference in suture material (thickness, rigidity and flexibility) used. Unable to ensure that the needle thread deviates from the normal position with each blow
And when the needle position (distance between needles; this type of sewing machine usually has four needles or three needles) is changed, the blowing device must be changed at the same time to reset the position of the blowing port, otherwise the needle thread cannot be blown away from the normal position correctly , making the blowing device more complex and costly in structural design and fabrication
[0005] In summary, there are still technical problems that cannot be solved in the prior art on the use of this blowing principle

Embodiment Construction

[0052] In order to better understand the technical content of the present invention, use and the effect that can be achieved, all preferred embodiments are listed in detail in conjunction with the accompanying drawings.

[0053] Please refer to figure 1 and 2 As shown in the figure, the jumping stitch device of the sewing machine of the present invention is installed in the machine base of the sewing machine, and is used to combine with the hook seat 2 in the machine base. The role of the needle, which includes:

[0054] A fixed seat 11, combined with the sewing machine body;

[0055] An eccentric shaft 12 is passed through the above-mentioned fixed seat 11;

[0056] A rocker 13 is combined with one end of the eccentric shaft 12, and the other end is combined with the hook stand 22 through the ball-and-socket connecting rod 21;

[0057] A connecting rod 14, located between the swing arm 321 on the horizontal axis 32 of the sewing machine and the rocking bar 13;

[0058] A...

Abstract

The invention relates to a skipping stitch device of a sewing machine, which mainly comprises a fixed seat, an eccentric shaft, a rocker, a connecting rod and a deflecting control rod. The fixed seat is combined with a sewing machine body and used for sleeving the eccentric shaft and a torsional spring; the eccentric shaft is inserted into the fixed seat; the rocker is combined with one end of the eccentric shaft, and the other end of the eccentric shaft is combined with a bearded needle table by a ball-and-socket connecting rod; the connecting rod is arranged between a swinging arm on a cross shaft of the sewing machine and the rocker; and the deflecting control rod is arranged at the other end of the eccentric rod. The skipping stitch device can be provided for an operator to control a connecting mechanism by the deflecting control rod to drive a bearded needle to make micrometric displacement, ensures that the bearded needle cannot hook the needle and lines and easily controls the action of a skipping stitch by controlling the deflecting control rod and other automatic control modes, thereby sewing and wrapping operations can be conveniently achieved, the procedures and the time of manual operation can be saved, and operation efficient workers can be increased.

Description

technical field [0001] The present invention relates to a stitch skipping device of a sewing machine, in particular, the operator can use the dial control lever to control the link mechanism to drive the hook needle to move slightly backward, so that the hook needle cannot catch the needle thread, so as to facilitate sewing hemming continuous worker. Background technique [0002] Press, the general chain mesh sewing machine is used to handle the sewing operation of the trouser waist, and it is often necessary to manually disassemble the two ends of the suture in order to fold and join the waist. In order to achieve the above operations, the hook needle can not catch the thread at both ends of the sewing head and tail, that is, the phenomenon of skipped stitches is formed, so as to save manual operation time and reduce operational troubles. [0003] In the prior art, there is an air blowing method to achieve the above-mentioned needle skipping purpose. Its structure is to in...
