Description
Technical field
The present invention relates to a kind of sewing machines to remove Bird's Nest device.
Background technology
When sewing machine starts to sew sewing, there are the end of a thread of certain length at eedle pinprick, the end of a thread is initial in sewing
It will appear the ball of string of one similar " Bird's Nest " at the back side of position, influence the quality of sewing.There are several kinds of processing " Bird's Nest " at present
Mode, such as with dial line device, electronics tension disk, although simple in structure, remove " Bird's Nest " effect it is undesirable.
Invention content
It cannot be removed effectively " Bird's Nest " present invention aim to address current sewing machine using line device, electronics tension disk etc. is dialled
The technical issues of.
For realization more than goal of the invention, the present invention provides a kind of sewing machine removal Bird's Nest device, including being set below head
Eedle, presser feet, crimping spring, tension disc, line hook, set square, bracket, connecting plate, stent and power source；
The crimping spring pushes down the tension disc, the line worked hard in glove with the set square respectively with the stent and connecting plate phase
Even, connecting plate described in the power source drive, connecting plate drive set square line to be made to hook in institute around the holder pivots certain angle
It states in bracket and is slided between tension disc below the eedle, so as to which the end of a thread of suture is hooked, when returning to initial position
Tension disc pushes down the end of a thread of suture.
Further, wraping plate is further included, the power source is fixed on the bracket, and stent is fixed by screws in described
On head；The elongated slot end of wraping plate described in power source drive is rotated around its axial screw, and one end of wraping plate is connected with the connecting plate
Move up and down connecting plate.
Further, the set square has the round elongated slot that resigning is slided for its axial screw.
Further, the connecting plate has the round elongated slot for driving its axial screw resigning.
Further, the line, which hooks front, has circular arc and Gou Xian areas.
Further, the bottom of the presser feet is equipped with thread cutter.
Compared with prior art, the beneficial effects of the invention are as follows：
Before sewing is started, power source is powered the present invention, and driving set square makes line hook within the carrier around holder pivots certain angle
From crimping Board position to eedle, lower section is slided, and so as to which the end of a thread of suture is hooked, power source power-off is resetted by torsional spring and hooks line
Tension disc pushes down the end of a thread of suture when returning to initial position.Starting sewing, eedle starts thorn cloth, and suture is left on above sewing,
Since sewing moves in sewing process to presser feet direction, cut off when suture encounters thread cutter, the end of a thread of suture is left on
Line is hooked between tension disc, and when sewing terminates, after completing trimming, power source is powered, and line, which hooks, to be stretched out, the end of a thread of suture fall and by
Removal, one-off are fully completed.It is acted above following circulating repetition, removes " Bird's Nest " effect formed by the end of a thread of suture
It is good.

Specific embodiment
The invention will be further described in the following with reference to the drawings and specific embodiments.
As shown in Figs. 1-5, sewing machine removal Bird's Nest device of the invention, be included in the eedle 3 of 1 lower section of head, presser feet 4,
Crimping spring 5, tension disc 6, line hook 7, set square 8, bracket 9, connecting plate 10, stent 11, wraping plate 12 and power source 13.Crimping spring 5
It is fixed with tension disc 6 by screw 51, crimping spring 5 pushes down tension disc 6 to adjust pressure of the tension disc 6 to line hook 7, and it is logical that line hooks 7
It crosses set square 8 respectively with stent 11 and connecting plate 10 to be connected, specifically, set square 8 is connected by its centre bore and the rotation of stent 11
It connects, 8 one end of set square is connected with connecting plate 10, and the other end hooks 7 with line and is connected.Set square 8 passes through 12 He of wraping plate in power source 13
Connecting plate 10 drive under turn an angle around stent 11, make line hook 7 in bracket 9 below eedle 3 between tension disc 6 edge
Slideway 16,17 slides, and Fig. 3 shows to be position below eedle 3, and Fig. 4 shows to be the position under tension disc 6, is exactly
It is slided between this two positions, so as to which the end of a thread 15 of suture 2 is hooked, tension disc 6 pushes down suture when online hook 7 returns to initial position
2 the end of a thread 15.
The action process of the sewing machine removal Bird's Nest device of the present invention is as follows：
Suture 2 passes through eedle 3, and suture 2 has the end of a thread 15, and the end of a thread 15 is located at 3 lower part of eedle；Before sewing is started, power source 13
Be powered, driving set square 8 turn an angle around stent 11, make line hook 7 in bracket 9 from 6 position of tension disc to eedle 3 below
It slides, so as to which the end of a thread 15 of suture 2 is hooked, power source 13 powers off, and set square 8 is driven to reset by connecting plate 10 and line is hooked 7
Tension disc 6 pushes down the end of a thread 15 of suture 2 when returning to initial position.Start sewing, eedle 3 starts thorn cloth, and suture 2 is left on sewing
Above, it since sewing moves in sewing process to 4 direction of presser feet, is cut off when suture 2 encounters thread cutter 41, suture 2
The end of a thread 15 is left on line and hooks between 7 and tension disc 6, and when sewing terminates, after completing trimming, power source 13 is powered, and line hooks 7 and stretches out,
The end of a thread 15 of suture 2 falls and is removed, and one-off is fully completed.It acts, is removed by suture 2 above following circulating repetition
The end of a thread 15 formed " Bird's Nest " effect it is good.
The present invention also have it is simple in structure, manufacture it is at low cost, it is easy for installation the advantages that.
Using above-mentioned desirable embodiment according to the present invention as enlightenment, by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property range is not limited to the content on specification, it is necessary to determine its technical scope according to right.
