Description
Technical field
The present invention relates to technical field of sewing machines more particularly to use in sewing machine presser feets.
Background technique
With the continuous development of apparel industry, present single needle sewing machine (abbreviation single needle machine) all generally has to be cut automatically
Line function, this function also bring a drawback while reducing labor intensity, i.e., in the production efficiency for improving operator
If do not dragged tightly online when playing seam, the reverse side of sewing just will appear a random line, is commonly called as " Bird's Nest " phenomenon, does not only result in sewing
Stitching portion out is smooth, unsightly, reduces the class of sewing, and also cause the waste of suture.Form " Bird's Nest " phenomenon
The reason is that stayed on needle after previous subtangent long the end of a thread when playing seam no-station pole canopy and caused by being brought to fabric reverse side.If risen
Give needlework some tension when seam, then the problem would not occur.
For this purpose, single needle machine all avoids the occurrence of " Bird's Nest " phenomenon using anti-Bird's Nest device at present, anti-Bird's Nest device mainly by
Electric control part (for controlling each mechanism action), wire-clamping device and this 3 part of anti-Bird's Nest presser feet composition, are sold on the market
Anti- Bird's Nest device is nearly all a kind of shared anti-Bird's Nest presser feet, as depicted in figs. 1 and 2.Anti- Bird's Nest device difference on the market
It is their wire-clamping device, is broadly divided into two kinds, is aspirated-air type wire-clamping device and mechanical wire-clamping device respectively.Aspirated-air type folder
Line apparatus is a special purpose machinery of Japanese Juki Corporation's Earlier designs, and clamp head and lint absorbing all use aspiration, mechanical to press from both sides
Line apparatus is then the common device that clamping the end of a thread is acted using mechanical device in market, and the purpose of both devices is all that will cut
The end of a thread after line is clamped.For mechanical wire-clamping device, the line comprising connection cylinder in the device hooks and tabletting, work
Cylinder stretches out when making, and the line hook hook being connected to above is retracted to the end of a thread, and the end of a thread is pushed down in tabletting, realizes wire clamping function.
Although the working method of aspirated-air type wire-clamping device and mechanical wire-clamping device slightly has difference, with they cooperate
Presser feet be almost it is the same, as illustrated in fig. 1 and 2, the presser feet for anti-Bird's Nest device of the prior art includes pressure foot 1 and cutter
2, it offers in pressure foot 1 from back to front along linear extension to front edge and the pin hole 11 that is open, the bottom surface of pressure foot

The needs of pin hole 11 in domain, presser feet are enlarged, and are needed chamfering on 12 side of take-up slot of presser feet, are processed a tiny metallic channel 13
(not having in common presser feet), enables blade exposing and line smoothly slides into the region.The pin hole 11 and metallic channel 13 of increasing are stitching
Fabric cannot be pushed down when processed well, be easy to cause bouncing pilotage and disconnection fault.When the needle code that sewing requires is bigger, line holds very much
It easily slides into metallic channel 13 and has caused seam broken string and sewing interrupt line, needlework are easy by presser feet when thicker part is stitched to thin location
It is also this reason that cutter 2, which is cut off,.In order to adapt to the sewing of all kinds of techniques, keep the remaining the end of a thread of seam short as best one can, needle is from cutting
The vertical range of the blade of knife 2 correspondingly needs to be transferred to 3mm or so, and remaining the end of a thread is also about 3mm at this time, affects sewing
The quality of technique, when sewing stitching and requiring very high, finished product also needs to carry out the operation of trimming hair by hand.
