Description
Technical field
The utility model belongs to knitting technology field, relate to knitting circular knitting machine knitting needle (crosspointer) arrange and lopping technology, specifically for double knit circular knitting machine based on to the one of pin lopping method to pin textile structural.
Background technology
In knitting technology field, circle latitude machine is a kind of the most common a kind of braiding apparatus, its topmost funtion part is cam system, comprise syringe, syringe is provided with needle tray, in needle tray, place knitting needle, knitting needle is driven in needle tray and is moved and realize narrowing and widening along needle tray by triangle, to complete knitting cycle.
Reversible cloth not only has the thickness advantage thicker than single-side fabric, and two-sided institutional framework can by design upper pin and lower pin different go out divider, realize more kinds of fabric structures and style, there is obvious jacquard weave advantage.Comprise two kinds for the round latitude machine that weaves reversible cloth, one is double cylinder single needle circle latitude machine, and another kind is common double-faced jacquard circle latitude machine.
Wherein, the first adopts double headed needle, because single needle restriction cannot realize double-faced jacquard, is only applicable to weave single organization's structure.Along with the continuous progress and development of the second braiding machine, the round latitude machine of double cylinder single needle structure is fewer and feweri, is more common at present in the tubular stocking machine that cannot adopt the second structure to realize two-layer fabric braiding, for the production of strip socks with jacquard weave not.
The second circle latitude machine, its knitting needle comprises two groups, pin and lower pin, wherein plays pin to be longitudinally arranged in the needle tray on bottom cylinder outer circumference face, upper pin is disposed radially in the needle tray on upper dials upper surface.Upper pin backshank points to the upper dials center of circle.Its lopping method is that upper pin and lower pin while or the pin that interlocks, complete at the same time or separately and move back the step such as circle, kinking lopping.Because this round latitude machine weaves respectively inside and outside two-layer fabrics by upper and lower two groups of pins, can go out divider and realize double-faced jacquard by setting difference.But this structure and one-tenth sired results skill, cannot be applicable in the little circular knitting machines such as the hosiery machine of common syringe diameter about 10cm.
For syringe diameter at the little circular knitting machine in 10cm left and right, due to size restrictions, cannot on upper dials, realize the setting of the various parts such as knitting needle, triangle, even if do not consider the setting of the parts of the control knitting needle folding and unfoldings such as triangle, backshank place circumferential length has also seriously limited the density of upper pin, causes knitting out high-density fabric.
For above-mentioned technical problem, a kind of feasible solution is, adopts with the top cylinder of bottom cylinder same structure (tubular structure) and substitutes the upper dials in existing double knit circular knitting machine, and top cylinder is relative with bottom cylinder, and upper pin longitudinally arranges, and syringe needle is downward.
While adopting above-mentioned solution, can combine in order to realize inside and outside two-layer fabric, upper pin and lower pin need be arranged in periphery Monday.If upper pin and lower pin are longitudinally oppositely arranged, even successively staggered lopping, in the time going out pin, the syringe needle of two knitting needles that are oppositely arranged up and down can bump against so.
Knitting machine emerges 200 for many years, loses all the time and has pair needle construction, generally because of like this.
If upper pin and lower pin stagger on circumference, in same circumferential length, the density of knitting needle reduces half so, and the Density knitting out accordingly also will reduce half.
In view of above-mentioned technical problem, double knitting technology is applied to little circular knitting machine, is difficult to realize the braiding of high density double knitting jacqard thing, becomes row industry personnel's common recognition.Therefore, enclose latitude machine side generation 100 for many years from two-sided, on market, not yet have the close pin roundlet of ripe double-faced jacquard machine product to come out.Even if having two-sided roundlet machine relevant programme to propose, also, because knitting needle limitations in density can be produced the factors such as the single Density of fabric category is low, cannot promote the use of.
Summary of the invention
The purpose of this utility model is for the problems referred to above of depositing in prior art, proposes a kind of being suitable for and upper and lower knitting needle is set and realizes the solution of double-faced jacquard lopping at minor radius circular knitting machine middle-high density.
For achieving the above object, first the utility model proposes a kind of double knit circular knitting machine to pin lopping method, the method comprises pin lopping and the large step of lower pin lopping two, it is characterized in that, described upper pin is arranged in same periphery with lower pin longitudinal relative (syringe needle of upper pin and lower pin aligns up and down), upper pin lopping step and lower pin lopping step are staggered the time and are carried out
Described upper pin lopping step comprises,
Fall pin and move back circle---knitting needle is descending, old coil from pinhock relatively knitting needle move to move back and enclose to shank, syringe needle is radially outward skew in the descending process of knitting needle, pinhock is from process inside new yarn,
The lopping of liter pin---knitting needle is up, and pinhock draws new yarn to form new coil to rising to the bait, and old coil relative knitting needle from shank is displaced downwardly to from syringe needle to deviate to be enclosed within new coil, and syringe needle is radially inwardly skew reset in the up process of knitting needle,
Described lower pin lopping step comprises
