Description
Technical field
The utility model belongs to sewing device technical field, refers in particular to a kind of with the sewing machine for hooking line apparatus.
Background technology
Sewing machine needs to leave the end of a thread of certain length at eedle eye, to protect when sewing cloth when starting sewing
The end of a thread will not be deviate from slave pinprick when having demonstrate,proved seam.The end of a thread of certain length is returned when playing seam on eedle eye stays in cloth sewing
Initial position can influence the attractive in appearance of cloth.
Processing mode at first is manually held the end of a thread when starting sewing, the end of a thread is stayed in above sewing, in sewing
After the completion of work, the end of a thread processing is repaiied by artificial progress.This processing mode is cumbersome.
In order to avoid the trouble of artificial treatment, the end of a thread was dialled when upper once sewing end using group line device later
Rise, when once being sewed after, by sewing machine thorn cloth line hook action, the end of a thread is taken to below sewing, it is ensured that the positive U.S. of sewing
See.
Also a kind of more universal mode is to set a kind of electronics tension disk in head passing channel, the electronics when playing seam
Suture is clamped certain time by tension disk action, hanging the end of a thread is brought to when playing seam below sewing, and pass through electronic clip
Line device clamps line, the line amount for dragging the end of a thread on eedle during seam by returning is supplied line, final realize shortens the end of a thread below sewing
Length.
Latter two has handled the mode of suture head, and due to sewing machine quick acting, the end of a thread can be deposited in seam when playing seam
Material is following, forms a nest like ball of string, is commonly called as " Bird's Nest " phenomenon, especially when playing the automatic reinforcing mode of seam, plays seam position " Bird's Nest "
Phenomenon is particularly evident.Although both modes solve the problem of there is the end of a thread above upper thread, but due to the end of a thread being transferred to
Below sewing, Bird's Nest ball of string problem is formd.
There is one kind to clamp the end of a thread by sliding wire-clamping device in current industry, blade is set on presser feet, rise logical during seam
Pullling for wire-binding device and sewing is crossed, makes to be cut off on the top presser feet edge of a knife of the end of a thread, " Bird's Nest " problem is solved.But this mode by
It is jammed in the end of a thread, when playing the first pin of seam, upper thread, which is tightened up, to take bottom line the end of a thread above sewing to, produces band bottom line and ask
Topic.It is that after the end of a thread is clamped, by a set of throwing device, the upper thread in head drawing lines is beaten to solve the mode of the problem to have one kind
Pine, has made have enough upper thread line amounts during seam, it is to avoid band bottom line problem.But this kind of routing mode has routing amount unstable
Defect, routing amount often can be excessive, cause suture head to receive not tight, and causes secant time delay, cut off rear the end of a thread remain it is long,
The throwing device of fixed journey system can not be met simultaneously needs different the rising of line amount to stitch the problem of take-up is unstable because needle gage is different.Together
When, because space is limited at head, the wire-clamping device of slip needs to stop pin position guarantee closer distance with presser feet and eedle, can shadow
Cloth passes through when ringing normal sewing operation, the problem of producing dossal.In addition, the end of a thread is hooked on moving in thread tension disc and slide rail,
When drag hook leaves thread tension disc, the end of a thread is difficult to deviate under thread tension disc, produces accumulation.Meanwhile, in order to avoid blade distance line too
Closely, the line normally sewed is sliced off, it is necessary to make blade set the pin hole line certain distance for leaving sewing, still, so causes secant
When cloth on remain longer the end of a thread.
The content of the invention
The utility model be for existing technology exist above mentioned problem there is provided with hook line apparatus sewing machine, this
Utility model technical problem to be solved is：How to realize and reliably trigger the end of a thread, be subsequently reliably to have cut off suture head,
And remained on sewing compared with the offer support of short-term head.
