Description
Technical field
The present invention relates to a kind of sewing-machine equipment technical field, particularly relating to a kind of presser feet and the Sewing machines that also excise unnecessary lace for sewing up double-layer cloth simultaneously.
Background technology
Refer to Fig. 1, it illustrates a kind of common sewing-machine foot in prior art, the briquetting 2 that it having depression bar 1 for being removably connected with Sewing machines, being fixed on depression bar lower end, and the front-end and back-end of briquetting 2 tilt slightly, so that feeding.Adopt the Sewing machines of this common presser feet, when sewing up the edge of double-layer cloth, such as upper strata is the flower pattern cut-parts that edge has special colored tooth, when lower floor is lace grenadine, the edge of lower floor's lace grenadine needs to exceed flower pattern cut-parts, after being sewed up along the colored tooth edge of flower pattern cut-parts by presser feet, the unnecessary lace grenadine in edge needs manual pruning to remove, not only waste time and energy, and clip flatness is coarse uneven after pruning, the double-layer cloth after sewing up will have a strong impact on product appearance after making for ready-made clothes (such as brassiere underwear, underpants).
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of presser feet and the Sewing machines that also fitly can excise unnecessary lace for sewing up double-layer cloth.
For achieving the above object, the present invention by the following technical solutions:
A kind of presser feet, comprise the depression bar removably connected with Sewing machines, the briquetting being fixed on described depression bar lower end, it is characterized in that: the side side of described briquetting is fixed with side plate along its length, the lateral surface of described side plate has the cutting knife spigot surface extended from top to bottom; The bottom margin of described side plate has the kink of lateral buckling in the bottom surface of described briquetting, forms the guiding channel extended before and after the length direction of described briquetting between the bottom surface of described kink and described briquetting.
Preferably, the part of the corresponding described guiding channel in bottom surface of described briquetting has the groove extended along its length, and described bending part is in described groove.
More preferably, the bottom surface of a little higher than described briquetting in the bottom surface of described kink.The difference in height of the bottom surface of described kink and the bottom surface of described briquetting is less than or equal to 1mm.
In one embodiment, the front portion of described briquetting has the arc transiting surface that the opposite side side from described guiding channel front end to described briquetting extends.
Wherein, the rear and front end of described side plate has a connecting portion be fixedly connected with described briquetting respectively.Described connecting portion and described briquetting are by being welded to connect.
The present invention also provides a kind of Sewing machines adopting above-mentioned presser feet, described Sewing machines has the driving shaft driving needle bar to move up and down, it is characterized in that: described driving shaft is also removably provided with the cutting knife with described needle bar synchronization action, described cutting knife matches with described cutting knife spigot surface.
Compared to prior art, the present invention has the following advantages: when adopting the Sewing machines with presser feet to carry out sewing up of double-layer cloth, by the kink of side plate, upper strata flower pattern cut-parts and lower floor's lace grenadine are separated, upper strata flower pattern cut-parts are by the guiding channel feeding of presser feet, lower floor's lace grenadine is from the kink bottom surface feeding of presser feet bottom surface and side plate, synchronously moved up and down with needle bar by cutting knife when sewing up, cutting knife cuts downwards along the cutting knife spigot surface of side plate and is excised by the excess margins of lower floor's lace grenadine, guarantees smooth cut, smoother; And presser feet can prevent cutting knife from damaging the colored tooth of upper strata flower pattern cut-parts, ensure that sewing up rear double-layer cloth has uniform seam; Use presser feet of the present invention and Sewing machines, drastically increase production efficiency, alleviate the labour intensity because manual pruning causes, improve the problem that colored sheet edge clip that handwork causes is uneven.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is described in detail.
Refer to Fig. 1 to Fig. 5, a kind of presser feet, comprise the depression bar 10 removably connected with Sewing machines, the briquetting 20 being fixed on depression bar 10 lower end, the side side of briquetting 20 is fixed with side plate 30 along its length, and the lateral surface of side plate 30 has the cutting knife spigot surface 31 extended from top to bottom; The bottom margin of side plate 30 has the kink 32 of lateral buckling in the bottom surface of described briquetting, forms the guiding channel 40 extended before and after the length direction of briquetting 20 between the bottom surface of kink 32 and briquetting 20.The part of the corresponding guiding channel 40 in bottom surface of briquetting 20 has the groove 21 extended along its length, and kink 32 is positioned at groove 21.The bottom surface of a little higher than briquetting 20 in bottom surface of kink 32, when installing side plate 30, the difference in height of the bottom surface of kink 31 and the bottom surface of briquetting 20 is less than or equal to 1mm.
In the present embodiment, the front portion of briquetting 20 has the arc transiting surface 22 that the opposite side side from guiding channel 40 front end to briquetting 20 extends, so that when starting to sew up, the colored tooth of upper strata flower pattern cut-parts is put into guiding channel 40.
The front end of side plate 30 has front connecting portion 33, and front connecting portion 33 is welded on the front end upper surface of briquetting 20.The rear end of side plate 30 has rear connecting portion 34, and rear connecting portion 34 is welded on the rear end upper surface of briquetting 20.
As shown in Figure 5, in the present embodiment, the kink 31 of side plate 30 is greater than rear portion width along the length direction upper forepart width of briquetting 20.The curved transition of forward edge of kink 31.
Refer to Fig. 6, the present invention also provides a kind of Sewing machines adopting above-mentioned presser feet, described Sewing machines has the driving shaft (not shown) driving needle bar to move up and down, described driving shaft is also removably provided with the cutting knife 50 with described needle bar synchronization action, cutting knife 50 matches with the cutting knife spigot surface 31 of side plate 30.
When the double-layer cloth 60 of this use in sewing machine to be flower pattern cut-parts 61 and lower floor in upper strata be lace grenadine 62 sews up; by the kink 32 of side plate 30, flower pattern cut-parts 61 and lace grenadine 62 are separated; the edge of the flower pattern cut-parts 61 on upper strata passes through guiding channel 40 feeding of presser feet; flower tooth is protected under the stop of side plate 30, avoids being cut to by cutting knife 50.The lace grenadine 60 of lower floor is from the bottom surface feeding of the kink 32 of the bottom surface of briquetting 20 and side plate 30, (in Fig. 6 the direction of arrow) is synchronously moved up and down by cutting knife 50 with needle bar when sewing up, when cutting knife 50 cuts downwards along the cutting knife spigot surface 31 of side plate 30, the excess margins of the lace grenadine 62 of lower floor is excised, makes smooth cut, smoother.
Adopt presser feet of the present invention and Sewing machines, substantially increase production efficiency, alleviate the labour intensity of manual pruning, and improve uneven, the irregular defect in lace edge that handwork causes.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
