Description
Technical field:
This utility model belongs to sewing machine technique field, refers in particular to a kind of sewing machine and removes Bird's Nest rapid changing knife band cutter presser feet.
Background technology:
Sewing machine, when sewing cloth, needs to leave the end of a thread of certain length at eedle eye place when starting to sew, during in order to have ensured to stitch, the end of a thread will not be deviate from from eedle eye. On eedle eye, the end of a thread of certain length can stay initial position formation " Bird's Nest " of cloth sewing when playing seam, affects the attractive in appearance of sewing.
In order to remove Bird's Nest, the processing mode commonly used at present is, is manually held by the end of a thread when starting to sew, makes the end of a thread stay above sewing, after sewing work, manually carries out repairing the end of a thread and processes.
The presser feet base plate 1 that current industry commonly uses has central authorities' wire casing 2, gear line end 3, off-line groove 4, it does not have install blade function (as shown in Figure 1, 2).
Having a kind of band cutter presser feet in current industry, on presser feet, central authorities' wire casing arc end leaves a gap, and slit aperture arranges blade, and the end of a thread top presser feet gap edge of a knife clamped when playing seam is cut off, and cuts off the end of a thread and solves " Bird's Nest " problem. But this with cutter presser feet owing to the edge of a knife of slit aperture is close from needle falling hole, suture head is just cut off together, thin material sewing be very easily cause sewing machine to play seam off-line. Meanwhile, the edge of a knife, again away from suture stitching center, can cause again when sewing thicker cloth that sewing upper thread the end of a thread is long, increases and prunes the end of a thread workload; The side of this presser feet has insert groove, and blade is fixed in insert groove by glue, changes and bother very much after breaks down, it is necessary to special instrument dismounts.
Current industry also has another kind of band cutter presser feet, on presser feet, central authorities' wire casing arc end is slotted backward, groove end away from arc end is provided with blade, and the end of a thread clamped when playing seam is cut off on the top presser feet groove end edge of a knife in feeding process, cuts off the end of a thread and solves " Bird's Nest " problem. But this structure is broken and changed the original gear line arc end of presser feet and off-line groove below, when sewing the softer sewing such as thin material, sewing is easily got into and is damaged sewed product in the groove offered and the problems such as dropped stitch occur; Thicker or when adding the sewing of floss sewing, suture mark can squeezed feed mouth, cut off suture mark, affect sewed product quality, increase defect ware. Meanwhile, the side of this presser feet also has insert groove, and blade is fixed in insert groove by glue, changes and bother very much after breaks down, it is necessary to special instrument dismounts.
