Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of chain sitch sewing machine, particularly a kind of thread hooking apparatus of chain sitch sewing machine.
Background technology
The sewing device of thick material in using seam to knit in current factory, mostly be general sewing machine to replace or oneself repacking, complex structure, the efficiency that wastes time and energy is low, easily occur the defects such as waste product, what most importantly their adopted mostly is single needle sewing machine, and they just cannot reach requirement for the higher product of requirement of strength.
For above-mentioned problem, people appreciate deficiency, and in addition improvement, a kind of hook line structure [application number: 200720306713.6 of three pin three chain type sewing machines disclosed in Chinese patent storehouse; Authorization Notice No.: CN201151805Y], comprise shank, pin folder, eedle, presser feet, needle plate, feed dog, left bending rack, middle bending rack, right bending rack, curved needle shaft, left looper, middle looper, right looper, this apparatus design left looper, middle looper, right looper, and they are separately fixed on corresponding left bending rack, middle bending rack, right bending rack, more left bending rack, middle bending rack, right bending rack are fixed on curved needle shaft.
Above-mentioned hook line structure is increased to the mode that have employed three staight needles, three loopers on the basis of original single staight needle, single looper mode, directly can improve sewing intensity by increasing stitching like this.In addition, above-mentioned hook line structure shortens for a long time than common flat seam machine on the stitching formed, because flat seam machine needs the upper thread grown to walk around shuttle very much in formation stitching process, cause same section of upper thread repeatedly back and forth through staight needle pin hole, therefore will have lost its intensity to a great extent.And in above-mentioned string-hooking mechanism, form suture needed for stitching shorter, suture back and forth rub sassafras and tortuous number of times also less, the intensity of therefore losing is also less, and this also just can improve the intensity of sewing greatly, to meet the demand that high strength is sewed.
But still there is a problem in above-mentioned hook line structure: staight needle can be subject to reaction force that fabric applies in through the process of fabric makes staight needle have trend to the direction motion of pin folder, and above-mentioned hook line structure is distributed in same angled straight lines by employing three staight needles, the penetration power that staight needle is acted on fabric is comparatively disperseed, above-mentioned reaction force is made to cause larger impact on staight needle through fabric, make staight needle comparatively painstaking in the process of puncture, and above-mentioned painstaking degree show on some thick fabrics especially obvious, thus have a strong impact on the quality of making chain-type stitch on thick fabric.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of thread hooking apparatus of chain sitch sewing machine, and technical problem to be solved in the utility model how to improve the quality of making thick fabric.
The purpose of this utility model realizes by following technical proposal: a kind of thread hooking apparatus of chain sitch sewing machine, chain sitch sewing machine comprises needle plate and is positioned at the pin folder on the upside of needle plate, thread hooking apparatus comprises three staight needles pressing from both sides with pin and fix, be positioned at three loopers on the downside of needle plate and the driving mechanism that simultaneously can drive three looper reciprocally swingings, it is characterized in that, the distribution triangular in shape of staight needle described in three, described needle plate has the needle plate hole worn for staight needle, needle plate hole has three and position and staight needle one_to_one corresponding, under the effect of driving mechanism, the needle point of three loopers can be relative with three staight needles respectively.
Chain sitch sewing machine also comprises the presser feet between needle plate and pin folder, presser feet runs through and has three through holes, and the position of three through holes and three staight needle one_to_one corresponding.During use, presser feet by cloth presser on needle plate; The pin hole of every root staight needle is all equipped with upper thread, and pin folder moves down and makes the related upper thread of staight needle pass through hole, cloth and needle plate hole successively together and be displaced downwardly on the downside of needle plate; Then, driving mechanism work drives three loopers to swing to staight needle direction to be hooked by three upper threads respectively simultaneously, and pin is clipped in while line is hooked three staight needles can be driven to reset, thus forms wire loop; Then, the feed dog being positioned at needle plate place drives cloth to move forward, and after cloth has moved, repeats above-mentioned action, to intersect formation chain-type stitch to make two wire loops.
In this thread hooking apparatus, three staight needle distributions triangular in shape, with the distance between two staight needles effectively shortening furthest apart in oblique three pins of the prior art, enable staight needle one among a small circle in cloth is punctured, the penetration power that staight needle is acted on thick fabric is comparatively concentrated, to enable staight needle comparatively swimmingly through fabric, thus effectively improve the quality that thick fabric makes.
In the thread hooking apparatus of above-mentioned chain sitch sewing machine, the distribution mode of the looper described in three is identical with the distribution mode of the staight needle described in three.
Namely under the effect of driving mechanism, three loopers can be distinguished simultaneously relative with three staight needles, and are hooked by upper thread simultaneously, make, while the operating efficiency ensureing thread hooking apparatus, to turn improve the quality that thick fabric is made.
In the thread hooking apparatus of above-mentioned chain sitch sewing machine, the staight needle described in three is acute triangle distribution.
Adopt above-mentioned structure, with the distance between two staight needles shortening furthest apart in oblique three pins of the prior art further, reduce the leg-of-mutton area that three staight needles are formed, make the puncture force of above-mentioned staight needle more concentrated, thus enable staight needle more swimmingly through fabric, to further increase the quality that thick fabric is made.
In the thread hooking apparatus of above-mentioned chain sitch sewing machine, the needle point of two staight needles adjacent in the staight needle described in three is not all distributed on same level straight line.
Adopt above-mentioned structure, wearing the mutual interference in cloth process effectively to reduce adjacent two staight needles, enable staight needle more swimmingly through cloth, thus improve the quality that thick fabric makes.
Compared with prior art, the thread hooking apparatus of this chain sitch sewing machine is identical with the distribution mode of three staight needles by the distribution mode arranging three staight needle distributions triangular in shape and three loopers, while the operating efficiency ensureing thread hooking apparatus, distance again between effective two staight needles shortening furthest apart in oblique three pins of the prior art, enable staight needle one among a small circle in cloth is punctured, the penetration power that staight needle is acted on thick fabric is comparatively concentrated, to enable staight needle comparatively swimmingly through thick fabric, thus effectively improve the quality that thick fabric makes.
