Abstract
The invention relates to a line-taking lever component for a double-needle sewing machine. An operation lever, a connecting lever and a connecting shaft of the line-taking lever component have an integrated structure; the connecting lever and the operation lever are fixed on the connecting shaft and are formed into an obtuse angle; an extending part toward the connecting lever is arranged on an end part of the operation lever; and two line holes are formed on the extending part. The line-taking lever component for the double-needle sewing machine avoids an operation of hinging the connecting lever with the operation lever of the traditional four-connecting-lever line-taking lever and has a reasonable structure. Two line holes are designed and are used together with the double-needle sewing machine, so that the convenience is brought to the double-needle sewing machine and the working efficiency is increased.
Description
Technical field
The present invention relates to a kind of thread take-up tension lever assembly of two-needle sewing machine, belong to Sewing machines accessory technical field.
Background technology
Sewing machines is in when work, and suture passes the pin hole of suture needle, and the reciprocating motion through suture needle drives suture and passes the stitching that clothing is realized clothing repeatedly.In order to make suture needle suture in the process that comes and goes keep certain rate of tension, avoid random line or broken string, generally on Sewing machines, be provided with thread take-up mechanism.Thread take-up mechanism is one of Sewing machines four big principal organ, and its performance quality is very big to the good bad influence of sewing work, and many disadvantages of Sewing machines, as the line that stretches tight, rolling line, broken string, vibrations, noise etc. all have substantial connection with thread take-up mechanism.The effect of thread take-up mechanism is in each work period of stitching forming process; Control the thread take-up tension lever supply and reclaim an amount of upper thread; The stitching that upper thread and bottom line are formed tightens up; And, move between two extreme positions of the cable-through hole on the thread take-up tension lever in one-period from needed line amount of using of stitching of spool extraction.
Traditional Sewing machines is generally single head single needle structure; The characteristics of this Sewing machines are the single needle thread take-up tension levers that only is provided with a shank on its needle bar frame and matches with it; The main feature of this single needle Sewing machines is that structure is unreasonable; Production efficiency is lower, and becomes the product that the weaving industry is progressively eliminated.Two-needle sewing machine is a kind of new architecture that on the basis of single needle Sewing machines, grows up, and the Sewing machines of two pins is arranged, and the effect of coming out is that two-wire is arranged side by side; Parallel each other, it has rational in infrastructure, and is easy and simple to handle; The production efficiency advantages of higher is the requisite machine of textile industry.
Summary of the invention
In view of the problem of above-mentioned existence, it is a kind of rational in infrastructure that the present invention provides, make simple, the crosspointer thread take-up tension lever assembly that is complementary and uses with two-needle sewing machine.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of thread take-up tension lever assembly of two-needle sewing machine, its working beam, connecting rod and connecting axle are integral structure; Said connecting rod and working beam are fixed on the connecting axle, form an obtuse angle; There is an extension towards connecting rod said working beam end, and two cable-through holes are arranged on it; Said connecting axle is made up of the cylinder of two hollows that connect up and down, and top periphery has screw thread, and following periphery has a screw.
Fluted on the pole face of aforesaid working beam.
Aforesaid connecting rod is the cylinder of hollow, the hole one and hole two of running through connecting rod is arranged, the axis in hole one and the parallel axes that is connected axis hole, the axis in hole two and the axis normal that is connected axis hole on it.
The height of cylinder is greater than the height of following cylinder above the aforesaid connecting axle, above the diameter of cylinder less than the diameter of following cylinder.
The thread take-up tension lever assembly of two-needle sewing machine of the present invention; Simple in structure, reasonable in design, particularly connecting rod and working beam are passed through the fixing integral structure of connecting axle; Avoided traditional four connecting rod thread take-up tension levers need connecting rod and the hinged operation of working beam have been reduced the use of parts; Screw thread that connecting axle is set and screw are used to connect the remaining part of sewing mechanism, install simple and convenient; The design of two cable-through holes can be used with two-needle sewing machine, provides convenience for two-needle sewing machine, has improved operating efficiency.
Description of drawings
Fig. 1 is the plan view from above of two-needle sewing machine thread take-up tension lever assembly of the present invention;
Fig. 2 is the side plan view of two-needle sewing machine thread take-up tension lever assembly of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, the thread take-up tension lever assembly of the two-needle sewing machine that the present invention is proposed is further explained.
See figures.1.and.2, be applicable to the thread take-up tension lever assembly of two-needle sewing machine of the present invention, its working beam 1, connecting rod 2 and connecting axle 3 are integral structure; Said connecting rod 2 and working beam 1 are fixed on the cylinder below the connecting axle, form an obtuse angle; Said working beam 1 is tapered to the end by the connecting axle place, and is fluted on the pole face, and there is an extension towards connecting rod the end; Two cable-through holes 4 are arranged on it, and two pins of corresponding two-needle sewing machine are during use; One group of upper thread passes a cable-through hole and corresponding with it suture needle, and thread take-up mechanism drives working beam and does periodic motion, thereby drives two groups of upper threads that are attached thereto; Supply and reclaim upper thread, work when guaranteeing crosspointer; Said connecting rod 2 is the cylinder of hollow, the hole 1 and hole 26 of running through connecting rod is arranged, the axis in hole 1 and the parallel axes that is connected axis hole, the axis in hole 26 and the axis normal that is connected axis hole on it; Said connecting axle 3 is made up of the cylinder of two hollows that connect up and down; The height of top cylinder is greater than the height of following cylinder; The diameter of top cylinder is less than the diameter of following cylinder, and top periphery has screw thread, is used to connect other rod member of thread take-up mechanism; Following periphery has screw 7, is used for fixing other parts of Sewing machines.
The present invention adopts connecting rod and working beam through the fixing integral structure of connecting axle, has avoided traditional four connecting rod thread take-up tension levers need connecting rod and the hinged operation of working beam have been reduced the use of parts; Two cable-through holes cooperate two pins of two-needle sewing machine to use, and carry out the take-up action synchronously, provide convenience for two-needle sewing machine, have improved operating efficiency.
The above is merely preferred embodiment of the present invention, does not limit the scope that the present invention implements with this, and the equivalence of doing according to technical scheme of the present invention and description changes and modification, all should belong to the scope that the present invention is contained.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
