Description
Technical field
The utility model belongs to sewing device technical field, is related to a kind of thread releasing mechanism of sewing machine.
Background technique
Industrial sewing machine generally can all use thread-loosening device, and existing thread-loosening device is driven by trimming electromagnet mostly
It is dynamic, then pass through the connection of loose ends steel wire, driving loose ends top plate is swung, and loose ends top plate driving loose ends mandril moves right, loose ends top
Bar pushes thimble, and thimble pushes thread tension releasing disc to move out, and wire-clamping device plate is made to lose spring pressure release, and plays the work of loose ends
With.But the device, since loose ends steel wire is too long, intervening resistance is larger, and trimming electromagnet could be driven with very big power.
To solve the above-mentioned problems, 204780185 U of China's patent CN discloses a kind of electronics for sewing machine loose ends
Thread-loosening device, it includes sewing machine case and the wire-clamping device that is mounted on the right side of sewing machine case, and wire-clamping device is that thimble-type presss from both sides
Line apparatus, and its thimble is penetrated into the inside of sewing machine case；It is provided with mandril on the left of thimble, support sleeve, a left side are cased on mandril
Side is provided with telescopic shaft, and support sleeve is connected by the bottom of bracer and sewing machine case；Telescopic shaft left end is pierced by sewing machine case,
And what is be pierced by is attached partially in electromagnet；Electromagnet is mounted on the left side of sewing machine case by mounting plate.
Although above-mentioned apparatus can be convenient later period maintenance to a certain extent, since second spring is frequently squeezed change
Shape is easy to appear fatigue failure, to influence normal reset, needs replacing second spring at this time, and above-mentioned apparatus is in replacement the
It when two springs, needs to remove complete equipment, maintenance is more inconvenient.
Utility model content
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of loose ends machine of sewing machine
Structure, the technical problem to be solved by the utility model is to how to improve the maintenance convenience of this thread releasing mechanism.
The purpose of this utility model can be realized by the following technical scheme:
A kind of thread releasing mechanism of sewing machine, the sewing machine include the tension disk being fixed on head of sewing machine, the folder
Sliding is provided with loose ends thimble in line device；The thread releasing mechanism includes support sleeve one, support sleeve two, transmission shaft one and transmission shaft
Two, the support sleeve one and support sleeve two are both secured on head, and the support sleeve one be located at tension disk and support sleeve two it
Between, the right end of the transmission shaft one passes through the support sleeve one and mutually reclines with the loose ends thimble, the right end of the transmission shaft two
Left end across the support sleeve two and the transmission shaft one mutually reclines, and electromagnet, the electromagnetism are further fixed on the head
The output end of iron is connected with the transmission shaft two；It is characterized in that, being fixed with spring base, the spring on the transmission shaft two
Pressure spring one is provided between seat and the left side of support sleeve one, and the contact surface of the transmission shaft one and transmission shaft two is located at the pressure
In spring one.
Its working principles are as follows: electromagnet drives transmission shaft two to move to right when loose ends, and then compression press spring one drives transmission shaft
One moves to right, so that loose ends thimble be driven to move, realizes loose ends.Loose ends thimble moves to right how to realize loose ends, can be as in background technique
As recording in mentioned patent document, the application subsequent content can also refer to the content.After loose ends, transmission shaft two
It moves to left, no longer exerts a force to transmission shaft one, transmission shaft one can reset under the action of pressure spring one, and tension disk is then in clamp shape at this time
State.It, can be manual as when fatigue, which occurs, in pressure spring one to be needed replacing since transmission shaft one is located in pressure spring one with the contact of transmission shaft two
Transmission shaft one is moved to right, it is made to occur spacing between transmission shaft two, can slightly pinch pressure spring one with left hand at this time, by it from biography
Spacing between moving axis one and transmission shaft two removes replacement, and without removing a whole set of thread-loosening device, maintenance can be improved
Convenience.
In a kind of thread releasing mechanism of above-mentioned sewing machine, it is provided with driving lever on half section of the right side side wall of the transmission shaft one,
The driving lever is between support sleeve one and tension disk.After design has driving lever, the mobile transmission shaft one of maintenance personal can be facilitated.
In a kind of thread releasing mechanism of above-mentioned sewing machine, the side wall of the transmission shaft one offers card slot, the driving lever
Inner end can be connected in the card slot.Design has card slot, when not needing maintenance usually, without driving lever to be inserted into, will not occupy
The inner space of sewing machine；When it is time for repair, driving lever is inserted into, then can fast moves transmission shaft one.
In a kind of thread releasing mechanism of above-mentioned sewing machine, the right side of the support sleeve one opens up fluted, the pine
Line mechanism further includes the gag lever post in groove, and the inner end of the gag lever post is articulated at one end of the groove, the limit
The other end of position bar is free end, and the gag lever post can make to be affixed on the left of the other end of gag lever post and the driving lever by swinging
It leans on.When it is time for repair, it drives transmission shaft one to move to right by driving lever, then gag lever post is taken out from groove, make the another of gag lever post
One end mutually reclines to form limit with driving lever, avoids transmission shaft one from springing back, and do not hold transmission shaft one manually, can vacate at this time
Both hands replace pressure spring one；After pressure spring one is replaced, gag lever post is reapposed in groove.
In a kind of thread releasing mechanism of above-mentioned sewing machine, the tension disk includes setting gradually along direction from left to right
Tension seat, thread tension disc one, thread tension disc two, baffle and adjustment seat are provided with pressure spring two, the pine between the baffle and adjustment seat
The right end of line thimble is connected with the baffle.When clamp, thread tension disc two is close to thread tension disc one under the action of pressure spring two, right
Suture is clamped；When loose ends, thimble is driven to move to right by electromagnet, transmission shaft two, transmission shaft one, thimble drives baffle to move to right
Compression compression two, so that thread tension disc two is no longer close between thread tension disc one no longer by the active force of pressure spring two, then realizes pine
Line.
Compared with prior art, the utility model has the advantage that
Since transmission shaft one is located in pressure spring one with the contact of transmission shaft two, as when, which there is fatigue, in pressure spring one to be needed replacing,
Transmission shaft one can be moved to right manually, it is made to occur spacing between transmission shaft two, can slightly pinch pressure spring one with left hand at this time, it will
Its spacing between transmission shaft one and transmission shaft two removes replacement, without removing a whole set of thread-loosening device, can mention
Height maintenance convenience.
