Description
Technical field
The present invention relates to Sewing machines, particularly relate to the anti-Bird's Nest device of a kind of flat seam machine.
Background technology
" Bird's Nest " is when namely flat seam machine plays seam, upper thread is stayed on presser feet face and is started sewing, and ball of string phenomenon appears in beginning place bottom line, and computer tangent line flat seam machine mainly uses a sewing thread, sewing is formed a kind of stitching, makes the machine that one or more layers sewing interweaves or unites by a seam.Usually thin material and thick material two kinds of purposes are divided into, computer tangent line flush joint function makes the goods such as fabric and leather, plastics, paper such as fiber crops, silk hair, artificial fibre, thin material is generally used for knitted underwear, shirt, uniform etc., thick material is generally used for all kinds of sportswear, jean, fashionable dress, overcoat, shoes and hats, case and bag etc., computer tangent line flat seam machine is the most basic car type at sewing device, there is Bird's Nest phenomena impair product quality, the more high shortcomings of defect ware rate in existing flat seam machine common fault bottom line when playing seam.
Publication number is that the Chinese invention patent of CN104911838A discloses a kind of Sewing machines removal Bird's Nest device and using method, this removal Bird's Nest device comprises the drag hook, clamp, eedle and the pressure foot that are positioned at below head, drag hook is connected with head by rotating shaft, eedle is provided with the pinprick passed for suture, pressure foot is positioned on needle plate, pressure foot is provided with the crossed beam trunking corresponding with eedle, and crossed beam trunking extends along the direction of sewing movement, and the bottom of crossed beam trunking is provided with thread cutter.This Sewing machines adopts arc swing hook wire clamp line apparatus, eedle the end of a thread after trimming is clamped, by the cooperation of the clamp loose ends time of two tension disks next time when playing seam, sufficiently stable line amount is provided for starting sewing, make to have tightened up seam upper thread fast when not being with bottom line, the end of a thread clamped is cut off in the position near sewing pin hole, and residual the end of a thread is short, and Ji is to solve the problem of Bird's Nest the end of a thread.
Publication number is that the Chinese utility model patent of CN204185662U discloses the anti-Bird's Nest device of a kind of computer tangent line flat seam machine, sewing machine main body is provided with anti-Bird's Nest device, and described anti-Bird's Nest device comprises loose ends electromagnet, hooks line apparatus and high and low press foot; Described high and low press foot comprises presser feet head, presser feet head lower end is provided with presser feet handle and presser feet keeps to the side, described presser feet top of keeping to the side is provided with two independently square column, described two square column inside are provided with mounting groove, be provided with elastic component in described mounting groove, inner side of keeping to the side with described presser feet inside described presser feet handle all has blade installation slot.It utilizes installation height presser feet in existing computer tangent line flat seam machine, hooks line apparatus and loose ends electromagnet, at the end of sewing, hook line apparatus hooks face the upper thread come up and clamps, then loose ends electromagnet upper thread pine once, when next sewing starts, hook under line apparatus keeps the upper thread clamped the prerequisite of reaching the standard grade and started seam, eedle thorn cloth, hook the face suture clamped of line apparatus to be cut off by the blade of high and low press foot, Ji is also saved simultaneously pluck line procedures to be realized not resident bird nest.
The secant blade of above-mentioned two pieces patent is all rectangles, between blade and the end of a thread be " cutting " but not the action of " cutting ", that is need larger active force that the end of a thread just can be made to disconnect between the end of a thread and the blade of blade, the blade of this blade is a straight line in addition, scope is 0-180 °, the blade that can only more renew after blade rust.In addition its to hook line apparatus external, be easy to link with the surrounding environment such as the end of a thread, cloth, human body in operation process, thus cause the use of the whole equipment of hook line apparatus deformation effect, even also likely cause larger loss of personal property.
Summary of the invention
For the above-mentioned technical problem existed in prior art, the invention provides the anti-Bird's Nest device of a kind of flat seam machine, comprise presser feet base plate 1, with the presser feet handle 2 of presser feet base plate hinged, it is characterized in that: presser feet handle 2 is arranged a hole, arrange aspiration channel 3 and line hook 4 in hole, line hooks afterbody patch and links plate 5; One end of the hinged connecting plate 6 in top of presser feet handle, the hinged described line of the other end of connecting plate 6 links plate 5; The cylinder block of presser feet handle also affixed cylinder 7, the piston rod of cylinder 7 and the middle part of connecting plate 6 hinged; The middle part of presser feet base plate arranges shallow slot, inlays dise knife 8 in shallow slot, arranges the gap 11 that can hold suture and penetrate, the gap, circumferential blade cover part 11 of dise knife 8 between two presser feets of presser feet base plate.
Further, the line hook compressing tablet 41 line being hooked to its guide effect is also set in hole presser feet handle 2 arranged.
Further, the making leaf spring 81 to its positioning action of dise knife 8 is set between presser feet base plate and presser feet handle.
Compared with prior art, blade of the present invention is rounded, its blade is 360 ° of circumference, and between the end of a thread be " cutting " but not the action of " cutting ", therefore minimum between the end of a thread and the blade of blade active force just can make the end of a thread disconnect, after the local rust of this blade cutting edge in addition, as long as blade is rotated a very little angle just can again become sharp, without the need to the blade more renewed, even can use throughout one's life.In addition its to hook line apparatus built-in, be not easy to link with the surrounding environment such as the end of a thread, cloth, human body in operation process, thus the use of the whole equipment of hook line apparatus deformation effect can not be caused, avoid causing larger loss of personal property.
