Abstract
The utility model discloses a sewing machine's presser foot automatic adjustment structure, contain a fixing base, the binding of fixing base below has the presser foot board that the groove was worn to several ways, should wear the inslot is equipped with corresponding several activity Board, between qieyu presser foot board and the activity Board, with mutually the equidistance be provided with buy car in installments the seam usefulness the several pinhole, see through the several elastic component who sets up between fixing base and the activity Board, mat activity Board below forms a free end, and when the different multistage of sewing utensil thickness stitches the thing, let activity Board still can adjust the optimum location automatically, it can steady pressure pull to reach the seam thing, improve seam thing in the dropped stitch condition of many sewing machine seams.
Description
Technical field
The utility model relates to a kind of presser feet automatic mechanism of sewing machine, relates in particular to a kind of utilizationMultiple movable pressing boards see through the appropriate location of automatically adjusting with seam thing thickness, improve seam thing in spininess sewingDropped stitch situation person.
Background technology
Commonly use the presser foot of sewing machine, because presser feet is designed to integral type, make presser feet in the pressure of compacting cloth coverBe mostly certain value, when presser feet is in the time pressing the seam thing of multilayer reflexed or overlapping, the compacting strength of this presser feet withoutMethod effectively obtains suitably and distributes, to such an extent as to location slit thing is easily because of cloth material and multi-layered thickness, in sendingWhen cloth, produce the phenomenon of out-of-flatness and fold, cause spininess sewing to produce dropped stitch problem, make suture quality not good.
Then there is dealer to develop the design that presser feet is split as to two joints, can determine according to area and the thickness of seam thingSurely be to press fixingly with single-unit or binodal, improve the aforementioned problem that cannot on average press; But for multistageThe seam thing of moulding, this binodal structure still cannot on average press, and is hereat still improved space.
At present, the solution of the aforementioned condition of production, is mostly and is dependent on staff in sewing process, asMeet dropped stitch problem, the sewing again of taking out stitches, for safeguarding sewing quality, institute's production efficiency that causes and production capacityDecline, cost promotes and the disappearance such as of poor quality, has in fact inconvenience part.
Therefore, how allowing presser feet steadily be pressed to carry out sewing, is the object of the utility model wish improvement.
Utility model content
The purpose of this utility model is to provide a kind of presser feet automatic mechanism of sewing machine, for reaching above-mentioned purposeAnd solve and commonly use problem, principal character of the present utility model is: comprise a holder, this holder belowLink and have several pressure foot of wearing groove and more than one movable pressing board, this is worn groove correspondence this activity is setPressing plate, and between between pressure foot and movable pressing board, with the equidistant several pin holes that arrange for sewing,And this is fixed be provided with elastic parts between movable pressing board, make this movable pressing board below form a free end, withCoordinate the thickness of seam thing to carry out adjustment of displacement.
Compared with previously commonly using structure, the utility model sees through multiple movable pressing boards and coordinates elastic parts,Can automatically adjust and the appropriate location of stitching thing thickness, allow the strength pressing be able to suitable distribution, reachIn sewing operation, significantly improve the cost depletion that dropped stitch causes and improve the object of the quality of sewing.Can further understand relevant the utility model for reaching above-mentioned purpose, feature for ease of those skilled in the artThe technological means adopting and effect thereof, hereby exemplify preferred embodiment and coordinate graphic being described as follows.

Detailed description of the invention
Conventionally according to the utility model, the feasible embodiment of this best, and coordinate after graphic detailed description,In order to do increasing understanding to the utility model, be not used in addition limitr of the utility model.
Refer to shown in the 1st figure～7th figure, the utility model is that a kind of presser feet of sewing machine is adjusted knot automaticallyStructure, has a holder 1, this holder 1 below link have several pressure foot 11 of wearing groove 111 withAnd more than one movable pressing board 12, this wear groove 111 be mainly used to correspondence arrange equal amount activity pressPlate 12, and between pressure foot 11 and movable pressing board 12, to arrange several for sewing with equidistantPin hole 13, and between this holder 1 and movable pressing board 12, be provided with more than one elastic parts 121, makeThese movable pressing board 12 belows form a free end 122, and the thickness that can see through seam thing 15 coordinates elastic parts 121Be adjusted to appropriate location.
Refer to shown in the 1st figure～2nd figure the arranged on left and right sides that this pressure foot 11 is worn groove 111 in severalRespectively be provided with a location division 16, this location division 16 is provided with to link holder 1 and movable pressing board 12Several locating holes 161, each locating hole 161 is circular hole, sees through corresponding several axostylus axostyles 112 and wears,Holder 1 can be linked with pressure foot 11 and movable pressing board 12; Wherein, each movable pressing board 12 is equalBe provided with a tank 124, this tank 124 is mainly used in configuring elastic parts 121, this elastic parts 121 inIn the present embodiment, be spring, but be not limited thereto; And be provided with between this pressure foot 11 and movable pressing board 12Pin hole 13, each pin hole 13, to form with equidistant setting, can coordinate 1～12 suture needle 14 to adjust,Or the suture needle of greater number 14, be not restricted to shown in figure.
Refer to again shown in the 3rd figure～7th figure, in the time that seam thing 15 is not sewed the part of projection, this presser feet122 of the free ends of plate 11 belows and seam thing 15 are fit-state, and this movable pressing board 12 is subject to elasticityAssembly 121 restrictions are parallel with this pressure foot 11; And there is certain thickness seam thing 15 when making multilayer foldingTime, this movable pressing board 12 can be stitched thing 15 thickness and be promoted, because the perforation 123 of this movable pressing board 12 is ellipseCircular design, limits therefore can see through axostylus axostyle 112, makes this movable pressing board 12 carry out upper and lower displacement action, inAfter seam thing 15 sewings, this movable pressing board 12 resets and is parastate with this pressure foot 11.
In sum, this pressure foot 11 of presser feet automatic mechanism mat of the sewing machine that the utility model providesIn wear groove 111, be equipped with several movable pressing boards 12 that can see through elastic parts 121 adjustment of displacements, and inBetween pressure foot 11 and movable pressing board 12, can pass for several suture needle 14 sewings with same spaced setPin hole 13, allows movable pressing board 12 by this in the time that the different multistage of sewing tool thickness stitches thing 15, still can be automaticAdjust optimum position, reach and steadily press this seam thing 15, make to commonly use the out-of-flatness of spininess sewing and fold and produceThe object that raw dropped stitch situation is improved completely.
