Preferably, the groove that the part of the corresponding described guiding channel in the bottom surface of described briquetting is extended before and after having along its length, described bending part is in described groove.
More preferably, the bottom surface of a little higher than described briquetting in 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 respectively a connecting portion being fixedly connected with described briquetting.Described connecting portion and described briquetting are by being welded to connect.
The utility model also provides a kind of Sewing machines that adopts above-mentioned presser feet, described Sewing machines has the driving shaft that drives needle bar to move up and down, it is characterized in that: on described driving shaft, be also removably provided with and the cutting knife of described needle bar synchronization action, described cutting knife matches with described cutting knife spigot surface.
Compared to prior art, the utlity model has following advantage: while adopting the Sewing machines with presser feet to carry out sewing up of double-layer cloth, kink by side plate is separated upper strata flower type cut-parts and lower floor's lace grenadine, upper strata flower type 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, while sewing up, synchronously moved up and down with needle bar by cutting knife, cutting knife cuts downwards the unnecessary edge excision of lower floor's lace grenadine along the cutting knife spigot surface of side plate, guarantees that otch is smooth, smoother; And presser feet can prevent that cutting knife from damaging the colored tooth of upper strata flower type cut-parts, guarantees that sewing up rear double-layer cloth has uniform seam; Use presser feet of the present utility model and Sewing machines, greatly improved production efficiency, alleviated the labour intensity causing because of manual pruning, improved the inhomogeneous problem of colored sheet edge clip that handwork causes.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is preferred embodiment elaborated.
Refer to Fig. 1 to Fig. 5, a kind of presser feet, comprise the depression bar 10 removably connecting with Sewing machines, the briquetting 20 that is fixed on depression bar 10 lower ends, a 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 extending from top to bottom; The bottom margin of side plate 30 has to the kink 32 of lateral buckling in the bottom surface of described briquetting, forms along the guiding channel 40 extending before and after the length direction of briquetting 20 between kink 32 and the bottom surface of briquetting 20.The groove 21 that the part of the corresponding guiding channel 40 in bottom surface of briquetting 20 is extended before and after having along its length, kink 32 is positioned at groove 21.The bottom surface of a little higher than briquetting 20 in bottom surface of kink 32, when side plate 30 is installed, the difference in height of the bottom surface of the bottom surface of kink 31 and 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 opposite side side from from guiding channel 40 front ends to briquetting 20 extends, so that while starting to sew up, the colored tooth of upper strata flower type 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 utility model also provides a kind of Sewing machines that adopts above-mentioned presser feet, described Sewing machines has the driving shaft (not shown) that drives needle bar to move up and down, on described driving shaft, be also removably provided with and the cutting knife 50 of described needle bar synchronization action, cutting knife 50 matches with the cutting knife spigot surface 31 of side plate 30.
This use in sewing machine is that flower type cut-parts 61 and lower floor are that the double-layer cloth 60 of lace grenadine 62 is while sewing up in upper strata; kink 32 by side plate 30 is separated flower type cut-parts 61 and lace grenadine 62; the edge of the colored type cut-parts 61 on upper strata is by guiding channel 40 feedings of presser feet; flower tooth is protected under the stopping 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 bottom surface of briquetting 20 and the kink 32 of side plate 30, while sewing up by cutting knife 50 with needle bar synchronously move up and down (direction of arrow in Fig. 6), when cutting knife 50 cuts downwards along the cutting knife spigot surface 31 of side plate 30, by the unnecessary edge excision of the lace grenadine 62 of lower floor, make otch smooth, smoother.
Adopt presser feet of the present utility model and Sewing machines, greatly improved production efficiency, alleviated the labour intensity of manual pruning, and improved inhomogeneous, the irregular defect in lace edge that handwork causes.
Above-described embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
