Abstract

The utility model discloses a broken faller of an anti-idle needle of a sewing machine which includes a faller body; a faller mounting hole, a first cloth distributing rack slot, a second cloth distributing rack slot and a third cloth distributing rack slot are arranged on the faller body; and a needle hole is arranged in the middle of the second cloth distributing rack slot. The broken faller of the anti-idle needle of the sewing machine is characterized in that one side of the needle hole is provided with a line pigtail knitting platform; when a tailed substance separates a presser foot and the faller, the tailing line is not cut off by the presser foot, the faller and cloth feeding teeth, etc, under the buffer of the line pigtail knitting platform, which can guarantee an operator to continuously tailor a plurality of tailed substances, and reduce the threading time wasted caused by broken line due to idle needle, thereby reaching the purposes of effective, simple and safe operation.

Description

The anti-empty needle broken string of Sewing machines needle plate

Technical field

The utility model relates to the Sewing machines needle plate, particularly relates to the anti-empty needle broken string of the flat seam machine needle plate of lock-type chain stitch.

Background technology

Sewing machines work principle roughly is: will make on the needle plate that thing is placed on Sewing machines, putting down presser feet pushes down and makes thing, the leftover bits and pieces pedal switch that tramps with one's feet again starts Sewing machines, utilize the reciprocating motion of walking the cloth tooth bar in the cloth rach slot, the compounding practice worker uses hand propelled, it is linked simultaneously by eedle bobbin to be carried the bottom line that carries with shuttle of reaching the standard grade, and pushes according to required direction of making making thing, finishes sewing.Because the formation of the flat seam machine stitching of existing lock-type chain stitch is carried out in cloth, wired knitting device of distinguishing above the Sewing machines needle plate as types such as overseam, flat-seams not on its needle plate, therefore after breaking away from eedle and presser feet, cloth will break at once, the operative employee can be often loses time because of broken string, threading, influences the progress of work.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of broken string of avoiding when cloth leaves eedle and presser feet is provided, the handled easily worker continues the sewing of next piece cloth at once, overcome the time that operative employee's threading is wasted, the anti-empty needle broken string of the Sewing machines of increasing work efficiency needle plate.

The technical scheme of the anti-empty needle broken string of the utility model Sewing machines needle plate is: comprise the needle plate main body, needle plate installing hole, first is set on the needle plate main body to be walked cloth rach slot, second and walks cloth rach slot and the 3rd and walk the cloth rach slot, walk second and to have pin hole in the middle of the cloth rach slot, a side that it is characterized in that described pin hole is shaped on line and distinguishes the woollen yarn knitting platform.

The utility model discloses the anti-empty needle broken string of a kind of Sewing machines needle plate, when making thing disengaging presser feet and needle plate, suture moves forward along with making thing, be shaped on line by a side and distinguish woollen yarn knitting platform (the oblique sphere of semi arch) at needle plate main body pin hole, online the distinguishing under the buffering of knitting platform of suture do not cut off by presser feet, needle plate and feed dog etc., guarantee that the operative employee makes thing to polylith and sews continuously, minimizing is wasted the time of threading because of empty needle causes broken string, thereby reaches efficient, simple, safe operation purpose.

The specific embodiment

The utility model relates to the anti-empty needle broken string of a kind of Sewing machines needle plate, as shown in Figure 1-Figure 3, comprise needle plate main body 1, needle plate installing hole 2, first is set on the needle plate main body to be walked cloth rach slot 3, second and walks cloth rach slot 4 and the 3rd and walk cloth rach slot 5, walk second and to have pin hole 6 in the middle of the cloth rach slot, a side that it is characterized in that described pin hole 6 is shaped on line and distinguishes woollen yarn knitting platform 61.When making thing disengaging presser feet and needle plate, suture moves forward along with making thing, be shaped on line by a side and distinguish woollen yarn knitting platform 61 (the oblique sphere of semi arch) at needle plate main body pin hole 6, online the distinguishing under the buffering of knitting platform 61 of suture do not cut off by presser feet, needle plate and feed dog etc., guarantee that the operative employee makes thing to polylith and sews continuously, minimizing is wasted the time of threading because of empty needle causes broken string, thereby reaches efficient, simple, safe operation purpose.
