Abstract

The invention belongs to the technical field of knitting and discloses a counter-knitting structure. The counter-knitting structure comprises upper needles and lower needles, the upper needles and the lower needles are arranged in needle grooves of an upper needle barrel and a lower needle barrel respectively, and the upper needle barrel and the lower needle barrel are arranged coaxially and rotate synchronously. The counter-knitting structure is characterized in that the upper needles and the lower needles are in axially one-to-one opposite arrangement, and a guide surface for guiding a needle head to radially deflect outwards in a needle outgoing process is formed in front of each needle in a needle outgoing direction. By opposite arrangement of the upper needles and the lower needles, more needles can be arranged in a unit circle, and accordingly fabric density can be improved effectively; due to independence of the upper needles and the lower needles, knitting of various fabrics can be realized by the counter-knitting structure just like a double-layer circular knitting machine. By means of interleaved looping and radial deflection of the needle heads, the serious problem of collision of the needle heads of the upper and lower needles in opposite arrangement is ingeniously and effectively solved.

Description

A kind of to needle braiding structure

The application is number of patent application is 2013104172996, and name is called that a kind of two-sided circular knitting machine is to point case application of pin lopping method and the application for a patent for invention to needle braiding structure.

Technical field

The invention belongs to knitting technical field, it relates to the knitting needle (two pin) of knitting circular knitting machine is arranged and lopping technology, specifically a kind of for two-sided circular knitting machine to needle braiding structure.

Background technology

In knitting technical field, circular knitting machine is a kind of a kind of braiding apparatus the most common, its topmost function part is divided into lopping system, comprise syringe, syringe is provided with pin groove, placing knitting needle in pin groove, knitting needle is driven to move along pin groove in pin groove by triangle and realizes narrowing and widening, to complete knitting cycle.

Reversible cloth not only has the thickness advantage thicker than single-side fabric, and two-sided weave construction can by design upper pin different from lower pin go out pin rule, it is achieved more kinds of fabric structures and style, have obvious jacquard weave advantage. Comprising two kinds for weaving the circular knitting machine of reversible cloth, one is double cylinder list pin circular knitting machine, and another kind is common double-faced jacquard circular knitting machine.

Wherein, the first adopts double headed needle, because single pin restriction, cannot realize double-faced jacquard, is only applicable to braiding single organization structure. Along with the continuous progress and development of the 2nd kind of braiding machine, the circular knitting machine of double cylinder list needle construction is fewer and feweri, is more common at present and cannot adopt in round hosiery machine that the 2nd kind of structure realizes double cloth weave, for the production of the strip socks of not band jacquard weave.

2nd kind of circular knitting machine, its knitting needle comprises pin and two groups, lower pin, wherein plays pin to be longitudinally arranged in the pin groove on lower syringe outer circumference face, and upper pin is arranged radially in the pin groove on dials upper surface. Upper pin backshank points to the upper dials center of circle. Its lopping method is, upper pin and lower pin simultaneously or the pin that interlocks, complete to move back the step such as circle, kinking lopping at the same time or separately. Because this kind of circular knitting machine weaves inside and outside two-layer fabrics respectively by upper and lower two groups of pins, go out pin rule realize double-faced jacquard by setting difference. But, this kind of structure and become sired results skill, cannot be applicable to common syringe diameter in the little round machine such as hosiery machine of about 10cm.

For syringe diameter at the little round machine of about 10cm, due to size limitation, the setting of the various parts such as knitting needle, triangle cannot be realized on upper dials, even if not considering the setting of the parts of the control knitting needle folding and unfoldings such as triangle, backshank place circumferential length also seriously limits the density of pin, causes knitting out high-density fabric.

For above-mentioned technical problem, a kind of feasible terms of settlement is, adopts and substitutes the upper dials in existing two-sided circular knitting machine with the upper syringe of the lower identical structure of syringe (tubular structure), and upper syringe is relative with lower syringe, and upper pin is longitudinally arranged, and syringe needle is downward.

When adopting above-mentioned terms of settlement, can combining to realize inside and outside double-deck fabric, upper pin and lower pin need to be arranged in circumference Monday face. If upper pin and lower pin are longitudinally oppositely arranged, even if successively staggered lopping, so when going out pin, the syringe needle of two knitting needles being oppositely arranged up and down then can bump against.

Knitting machine emerges 200 for many years, loses all the time and has needle construction, generally because of so.

If upper pin and lower pin are at circumferential Iy offset, so in same circumferential length, the density of knitting needle then reduces half, and the thread count knit out accordingly also will reduce half.

In view of above-mentioned technical problem, double knitting technology is applied to little round machine, it is difficult to realize the braiding of high-density double-faced jacquard knitted fabrics, becomes the common recognition of row industry personnel. Therefore, emerge 100 for many years from the two-sided latitude machine that encloses, market not yet has the little round machine product of the ripe close pin of double-faced jacquard come out. Even if there being the relevant scheme of two-sided little round machine to propose, also because the restriction of knitting needle density, the factors such as the single thread count of fabric category is low can be produced, cannot promote the use of.

Summary of the invention

It is an object of the invention to for the problems referred to above deposited in prior art, it is proposed to a kind of being suitable for arranges upper and lower knitting needle at little radius circle machine middle-high density and realize the solution of double-faced jacquard lopping.

For achieving the above object, first the present invention proposes a kind of two-sided circular knitting machine to pin lopping method, the method comprises pin lopping and the big step of lower pin lopping two, it is characterized in that, described upper pin is longitudinally relative (syringe needle of upper pin and lower pin aligns up and down) with lower pin to be arranged in same circumference face, upper pin lopping step and lower pin lopping step are staggered the time and are carried out

Described upper pin lopping step comprises,

Falling pin, to move back circle knitting needle descending, and old coil moves to move back from knitting needle relative in pinhock and encloses to pin bar, and syringe needle is radial direction shift outward in the descending process of knitting needle, pinhock from process inside new yarn,

Rising row on pin lopping knitting needle, pinhock draws new yarn to form new coil to rising to the bait, and old coil relative knitting needle from pin bar is displaced downwardly to deviate to be enclosed within new coil from syringe needle, and syringe needle is radial inward deflection reset in row process on knitting needle,

Described lower pin lopping step comprises

Rising pin and move back row on circle knitting needle, old coil moves to move back under knitting needle relative in pinhock and encloses to pin bar, syringe needle radial direction shift outward in row process on knitting needle, pinhock from process inside new yarn,

Falling pin lopping knitting needle descending, the downward hook of pinhock draws new yarn to form new coil, and old coil moves to deviate to be enclosed within new coil from syringe needle on relative knitting needle from pin bar, and syringe needle radial inward deflection in the descending process of knitting needle resets,

Described upper pin and lower pin are in hand-manipulating of needle process, and the radial maximum offset of syringe needle is from identical.

The present invention breaches the centuries, and general thought circular knitting machine knitting needle can only, along the mindset of syringe axial linear movement, creatively propose to turn to and the knitting needle hand-manipulating of needle scheme of radial two direction compound actions along syringe a kind of comprising.

Needle construction (, on the same line, syringe needle is oppositely arranged for upper pin and lower pin) is designed by pin lopping method being directed to specially of the present invention. Upper pin with under arrange for pin, the more knitting needle of magnitude setting in unit perimeter can be conducive to, can effectively improve the density of fabric, for the syringe size of existing 220 pin one side circle hosiery machines, application technical solution of the present invention, it may be achieved the process for processing of double-deck 220 pin high density product. Because adopting independent upper pin and lower pin (non-double end crochet hook), two groups of pins can set as required and respective go out pin rule, so the same with double-deck large circle machine variation fabric can be knit out, it is achieved little round machine double-faced jacquard function. The present invention staggers the time lopping by upper pin and lower pin and coordinates the mode of syringe needle radial direction skew, make knitting syringe needle in knitting cycle, it is on different circumference face from relative knitting syringe needle, ingenious and efficiently solve the upper and lower serious problems two pin syringe needles being difficult to avoid being set for pin and bumping against.

In the above-mentioned methods, the radial maximum offset of described syringe needle from, time overlapping with subtend syringe needle with it, ensure that it is offset to and be as the criterion outside subtend syringe needle, generally, the radial departure distance of syringe needle is greater than subtend knitting needle arrives pin groove bottom before going out pin radial maximum width outside syringe needle. When subtend knitting needle go out pin front have outer ledge be greater than outside the syringe needle of this subtend knitting needle to the structure of the radial maximum width of pin groove bottom to the radial maximum width of pin groove bottom time, the radial offset of syringe needle is as the criterion with the radial maximum width of the outer ledge to pin groove bottom that are greater than this structure.

Syringe needle can go out to complete gradually in pin or narrowing process skew or reset, until syringe needle and relative knitting syringe needle realize the radial maximum width that departure distance is greater than outside subtend syringe needle to pin groove bottom radial overlapping front a moment, namely syringe needle shift outward and/or the action that inwardly resets continue whole go out pin and narrowing process. Also can complete skew in a certain period in the process going out pin or narrowing or reset, namely the action of syringe needle shift outward from going out pin until the syringe needle of syringe needle and subtend knitting needle radial overlapping before process in a period in complete, syringe needle inwardly reset action from knitting with subtend depart from overlapping until knitting needle completes to complete in the period in the process narrowed.

The skew of described syringe needle can be accomplished in several ways, and here is three kinds of relatively preferred feasible patterns:

Its one, by going out needle path footpath is provided with outer inclined lead-in chamfered blocking structure realize;

Its two, inside knitting needle near the half portion of syringe needle arrange can syringe moves radially relatively top part, by radially outward moving of a top part, promote knitting needle outwards to realize offseting;

Its three, arrange inside syringe not with syringe rotate, parts corresponding and synchronous with raising cam and depressing cam, on these parts correspondence knitting needle near the half portion of syringe needle, there is the convex surface along syringe circumferential direction smooth excessiveness or flange. When syringe turns to a certain knitting needle pin through raising cam stitch groove starting point or before, also just through convex surface or flange protruding starting point in a circumferential direction inside this knitting needle, and at stitch through super pin depressing cam stitch groove terminal or afterwards, also just through convex surface or flange projection terminal in a circumferential direction inside knitting needle.

Of the present invention in pin lopping method, described knitting needle go out pin and narrowing action can adopt conventional raising cam and depressing cam to realize, it is also possible to adopt existing digitalized needle selecting machine to realize. In order to improve the reliability of lopping, the existing parts for held loop such as sinker, grid tooth can also be applied in braiding process equally.

In addition, owing to upper pin is longitudinally arranged by the method for the invention, and syringe needle is down. So, after needle latch is opened, due to the factor such as vibration of knitting machine, needle latch probably fell under deadweight effect before catching yarn and closes pin mouth phenomenon. Cause lopping failure, cause leakage pin. In order to prevent this kind of problem, ensure that knitting cycle reliably completes, the parts stopping that needle latch falls can must be set at section one section of circumference place staying open by corresponding needle latch in the outside of syringe equally, protect the parts such as needle plate such as routine. Certainly, except upper pin needle latch is because except deadweight falls, the lopping system being applicable to the present invention is the same with routine circular knitting machine, and the needle latch of lower pin also exists the possibility closing pin mouth because of centripetal force effect, same can also being suitable for by lower pin protects needle plate, to guarantee reliably completing of knitting cycle.

Based on above-mentioned to pin lopping method, the present invention propose a kind of relative to preferably for realize the syringe needle of the method and offset and reset action to needle braiding structure, comprise pin, lower pin, upper pin and lower pin are separately positioned in the pin groove of syringe and lower syringe, described upper syringe and lower syringe are coaxially arranged, and synchronous axial system, it is characterized in that, upper pin (goes up pin identical with lower pin quantity with lower pin along axial being oppositely arranged one to one of syringe, and it is in same circumference face, upper pin syringe needle is downward, lower pin syringe needle is upwards, upper pin and lower pin align vertically one to one), the pin front that goes out of every piece of knitting needle is equipped with one and can go out in pin process the guide surface guiding syringe needle radially outward to offset.

Described guide surface, for promoting syringe needle footpath outwards inclined, therefore, is arranged on going out on needle path footpath of syringe needle. Guide surface to be realized guiding function, should have an inclination angle, so that when guide surface contacts with syringe needle end face, it is possible to syringe needle is produced an outside component. Guide surface can also have certain radian, i.e. convex surface, or concave surface, wherein preferred convex surface.

Described guide surface can by being arranged in pin groove and convexing to form that pin groove bottom one is connected, can also be formed by the surface, position of the corresponding pin groove of other parts being arranged on pin groove front (going out pin direction), extend on the outer in pin groove front as being formed at raw gram seat. Consider pin slot machining difficulty problem, it is preferable that guide surface is formed on other parts.

For realizing of the present invention radially-inwardly being resetted by knitting needle in pin lopping method, it is possible to be respectively equipped with, outside pin and lower pin, the assembly or parts that syringe needle can be impelled radially-inwardly to reset when narrowing on described. As, the spring piece that the arranged outside one of each piece of knitting needle is pressed on knitting needle; For another example, the spring ring being enclosed within outside syringe; Again or, after be provided with compression spring, be pressed on briquetting outside knitting needle etc. above.

Above-mentioned knitting element needle braiding structure mixed the necessity such as yarn carrier, sinker or assists, can become a kind of to pin lopping system.

Said structure only improves for the setting of knitting needle and the design that goes out needle path footpath, and the other parts of lopping system, such as the parts that the parts such as yarn carrier, sinker are all suitable in common round machine latch needles lopping system. So tired stating is not done at place.

Go for pin lopping method it should be understood that of the present invention any comprising the various lopping systems to needle construction, and it is not limited to the lopping system that pin is all arranged by whole knitting needle. Provide an example below: upper pin is less than lower pin, and on every root, pin is relative with a lower pin, and equally, upper pin goes out to arrange guide surface structure on needle path footpath, at least with on go out needle path footpath is also arranged guide surface structure for the lower pin answered.

Embodiment

With reference to Fig. 1,2, of the present invention to pin lopping method, its knitting cycle is divided into pin lopping and the big step of lower pin lopping two, and two big steps are staggered the time and carried out, and after whole actions of one complete, another one side starts action. Even if not exclusively staggering the time, one of them person the withdraw of the needle to its syringe needle leave hook yarn position, another one could start pin, and ensures that the former completes in whole action when the another one hand-manipulating of needle is to hook yarn position.

The each key operations state of lopping action is divided and is seen a-g in Fig. 1 or Fig. 1, described upper pin lopping and lower pin lopping step all can be divided into pin to move back circle, the big step of narrowing lopping two substantially, further, can be subdivided into: move back circle, skew, pad yarn, kinking, reset, lopping six actions. Following pin is example, and each action details is as follows:

Move back circle: on knitting needle row, old coil descending relative to knitting needle, in the process of old coil lower slip each relative to knitting needle, needle latch is opened (or needle latch opened by the spy special needle latch parts of opening such as fishing before knitting needle enters weaving position), on rear slide needle lever, knitting needle goes upward to pinhock opening place to be stopped after the new yarn in yarn carrier yarn mouth place.

Skew: on knitting needle in the process of row, radial along syringe, offset laterally, make syringe needle deviate initial circumference face. For upper row hook yarn is prepared, prevent from bumping against with upper pin syringe needle.

Pad yarn: yarn mouth action, by new yarn pad at pin mouth, hook yarn time descending in order to knitting needle.

Kinking: knitting needle is descending, pinhock hooks to pad to lead downwards at the yarn of pin mouth and draws, and straight yarn is bent to half-turn.

Reset: knitting needle hooks in the descending process of yarn, and syringe needle radially-inwardly offsets along syringe, returns initial circumference face gradually.

Lopping: this step can also be called knocking over, while knitting needle deviate from by old coil, new coil is formed. Simultaneously or generations that partly overlap, namely in the descending process of knitting needle, old coil slides into below needle latch from pin bar, and promotion needle latch upwards closes pin mouth further, and new yarn is closed in pinhock by needle latch for knitting cycle and reset action. After pin mouth is closed, old coil breakked away from needle latch, deviate from from syringe needle, was enclosed within new coil. New coil is formally formed. A complete single pin lopping action terminates.

Upper pin knitting cycle is substantially identical with lower pin, and difference is, it is contrary with the direction of action of narrowing that knitting needle goes out pin.

With reference to Fig. 3-5, the present invention propose to needle braiding structure, part-structure is identical with common circular knitting machine, comprise, syringe, knitting needle, syringe is cylinder shape, the syringe outer side wall circumference evenly some pin grooves 1 of arrangement, knitting needle is arranged in pin groove 1, upper syringe 2 is provided with the identical pin groove 1 of quantity with the outer wall of lower syringe 9, arranges one piece of upper pin 3 in each pin groove of upper syringe 2, and syringe needle is downward, arranging one piece of lower pin 10 in each pin groove of lower syringe 9, syringe needle is upwards. Special part is, the pin groove of upper syringe and the pin groove of lower syringe align one by one, and equally, upper pin 3 is also longitudinally relative with lower pin 10.

Be provided with inside upper syringe 2 for assembling grid tooth 11(for held loop during upper needle knitting) grid fluted disc 5, along extending laterally under grid fluted disc, the part 6 stretching out pin groove bottom goes out pin front at upper pin and forms the inclined-plane guiding syringe needle extroversion skew.

Being provided with the life gram seat 8 for assembling sinker (for held loop during lower needle knitting) inside lower syringe 9, along extending laterally on raw gram seat 8, the part 7 stretching out pin groove bottom goes out, at lower pin, the inclined-plane that pin front forms guiding syringe needle extroversion skew.
