Background technology
Loom shuttle is the device in weaving process for wefting insertion.Yarn through warp thread shed open, coordinates the beating parts on loom, completes the weaving process of fabric under the guiding of shuttle.Therefore, shuttle is requisite significant components in weaving process.Mostly shuttle is to determine with kaki, Qinggang oak, lamination wood or what the material such as nylon was made, size and shape stochastic pattern and needs, has coefficient of friction little, the feature of tough and hard wear resistant.Shuttle draws yarn when weaving, and due to the inertia of shuttle wefting insertion action, can cause that weft yarn is storing unwinding excessive on the spool of weft yarn, so that weft yarn relaxes, the phenomenon of burr occurs in fabric, affects final product quality.Method conventional at present is the way installing shuttle hair on shuttle additional, and the method utilizes shuttle hair that the frictional force of yarn prevents the excessive unwinding of yarn, avoids the generation of fabric burr problem to a certain extent.But, when weaving speed is high, wefting insertion frequency is big time, the effect of shuttle hair reduces, and weft yarn still there will be the problems such as lax, tension force is too small.And, when weaving high-tech smallware, control for weft yarn requires more strict, the weft yarn active length that each wefting insertion needs is short, if weft yarn occurs in that lax phenomenon at a certain latitude place, owing to shuttle hair device does not possess weft tension control, the relaxed length of this weft yarn can not be fully used when the weaving of next latitude, causes the appearance of burr problem.It addition, carry out along with woven, Suo Maoyi occurs that tired and weft yarn and spool integral diameter reduce, and causes that weft yarn frictional resistance is reduced by shuttle hair, and the lax control effect of weft yarn is weakened by shuttle hair gradually.Therefore, shuttle hair can not effectively overcome the defect of fabric burr.
Owing to the shuttle of Tradition Looms does not have weft tensioner part, lax weft yarn can not be retracted in the storage pirn in shuttle, generally requiring and move back the weft yarn that latitude or manual adjustments are lax, cause troublesome poeration, waste time and energy in weaving process, work efficiency is low.For example, utilize the multi-shuttle box rigid rapier weaving machine described in China Patent Publication No. CN101215749A and CN101078150A, during weaving tubing, it may appear that the phenomenon of fabric burr, cause that the performance of tubing is decreased obviously, it is impossible to meet application requirement.Therefore, invent a kind of Novel shuttle with weft tension control and lax weft yarn restoring device, significant.
Summary of the invention
The invention aims to overcome deficiency of the prior art, it is provided that a kind of novel loom shuttle, there is weft tensioner and the restoring device of lax weft yarn.It is applied to fly-shuttle loom, especially multi-shuttle box rigid rapier weaving machine, overcomes fabric burr that the shuttle of Tradition Looms is likely to occur in wefting insertion process, weave the problems such as uneven, improve weaving efficiency, improve product quality class.
The technical scheme is that a kind of loom shuttle with weft tensioner, there is the housing of cavity and yarn guiding port including centre, the spool storing weft yarn is set in housing, on the described spool fixing steel wire that to be set in housing axial, also including symmetrical two weft tensioner being arranged on spool both sides, each described weft tensioner all includes: the setting of casing below rotating circular disk, rotating circular disk, the upper sleeve pipe above rotating circular disk;Having the lower half circle cylinder and lower spring that contact with described rotating circular disk inside described setting of casing, described upper inside pipe casing has the upper semi-circle cylinder contacted with described rotating circular disk, upper spring and the upper adjustment screw touched with described upper spring interface;Also have and connect described rotating circular disk and the main spring on spool.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one: shown in accompanying drawing 1,2, a kind of loom shuttle with weft tensioner, including the cavity housing 1 with yarn guiding port 6, store the spool 5 of weft yarn, the main spring 3 of torsional moment can be produced, be fastened transversely to the fixing steel wire 2 in housing.Housing 1 is made up of nylon material, this material have wear-resisting, resistance to roll, resistance to punching, good stability of the dimension and fatigue resistance high;Surface processes through coating, and wearability, static electricity resistance and excellent radiation performance meet the needs of weaving process.The fixing steel wire 2 of replaceable spool 5 is fine grain hot-rolled high-quality steel HRBF500 material, more than yield strength 500MPa, elongation percentage more than 15%, and one end of fixing steel wire is fixed with housing, the position being retrained steel wire by the recessed grain on housing of the other end.When changing spool 5, will be located in the fixing steel wire 2 of groove one end and transfer to from groove, change new spool 5.Spool 5 two ends storing weft yarn are connected with bayonet lock 4 respectively, and the cross section of bayonet lock 4 is triangle, it is also possible to be X-shaped or other shapes, as long as guaranteeing not occur Relative sliding.Bayonet lock 4 is connected with the main spring 3 that can produce torsional moment away from one end of spool, and the other end of the main spring 3 that can produce torsional moment is connected with rotating circular disk 7.
Arrange symmetrical two weft tensioner in the both sides of spool 5, each weft tensioner includes: the setting of casing 12 below rotating circular disk 7, rotating circular disk 7, the upper sleeve pipe 8 above rotating circular disk;Setting of casing 12 is internal has the lower half circle cylinder 14, lower spring 13 and the lower adjustment screw 15 that contacts with lower spring that contact with rotating circular disk 7, and upper sleeve pipe 8 is internal has the upper semi-circle cylinder 11, upper spring 10 and the upper adjustment screw 9 that contacts with upper spring 10 that contact with rotating circular disk 7.
Be stored in spool 5 weft yarn and be pulled from yarn guiding port 6 draw time, the rotation of spool 5 drive main spring 3 to reverse to produce resilience force be F1.By the degree of tightness of upper adjustment screw 9, regulate the frictional resistance with upper semi-circle cylinder 11 when rotating circular disk 7 rotates, this frictional force be sized to F2.When weaving process introduces weft yarn, it is stored in spool 5 weft yarn and is pulled and draw from yarn guiding port 6, due to the increase of weft tension, work as F1> F2, rotating circular disk 7 starts to rotate, and drives main spring to twist, thus promoting the spool 5 storing weft yarn persistently to rotate release weft yarn.When the weft yarn that weft tension reduction causes is lax, now F2> F1, the main spring generation turn-back that is connected with spool, drive the spool storing weft yarn to rotate backward, store up occurring lax weft yarn to be retracted in pirn.So circulation is repeatedly, and it is F that the rotation of spool 5 causes main spring 3 to reverse generation resilience force1, and there is frictional force F on rotating circular disk 72Mutually contend with so that weft yarn remains a range of tension force, weft yarn constantly can either be drawn from yarn guiding port, the weft yarn relaxed can be promoted again to be retracted in spool 5, it is to avoid it excessively unwinds.
Embodiment two: shown in Figure 3, a kind of loom shuttle with weft tensioner, its structure is similar to embodiment one.Along with shuttle uses the increase of time, semicylinder and and rotating circular disk between coefficient of friction can change, the effect so changing frictional force by regulating screw will weaken to some extent, now screw must carry out large range of adjustment, in turn result in rotating circular disk deviation original position within shuttle, go wrong.In order to effectively improve this defect, we can the position symmetrical about shuttle centrage increase simultaneously one and on regulate screw 9 there is the lower adjustment screw 15 of identical action effect.Good effect can be reached by regulating the symmetrical screw of this group when shuttle uses, mainly include two aspects.One: one group of symmetry acts on while regulating screw, it is possible to more accurate regulating friction force, this also implies that can according to the difference of tension force needed for different yarns, suitable adjustment frictional force, reaches better tension force and controls effect;Adjustment screw its two: groups symmetrical avoids single adjustment screw Problems existing, because when screw is carried out large range of conciliation by needs, it is likely to result in rotating circular disk deviation original position, and produce friction with fixing steel wire, this frictional force is unstable and uncontrollable, control to have undesirable effect to the tension force of shuttle, and the appearance of one group of symmetry adjustment screw just can avoid this problem, regulate this group simultaneously and regulate screw, can also ensureing that rotating circular disk is in center all the time while changing frictional force, it is more stable that the tension force of shuttle controls effect.
Embodiment three: such as the kit-of-parts described in embodiment one, two, together constitute the loom shuttle device with weft tension control function, this device can according to different needs, change semicylinder and realize the good effect controlling weft tension with the frictional force of rotating circular disk, although this device effect is fine, but relative complex.Sometimes the control effect of tension force is not had significantly high requirement by weft yarn, and only having only to it, to be maintained at non-relaxed state just passable.Based on this, design a kind of simple easily processing and the loom shuttle that weft yarn can be made to be maintained at non-relaxed state, particularly necessary.This shuttle device, omit the weft tension described in embodiment one or two and control device 3,4,7,8,9,10,11,12,13 and 14, two grooves are had respectively in the yarn guiding port both sides of shuttle, each fix a weft tension control spring in wherein, spring one end is fixed on portion in shuttle body, other end rounded (yarn-guiding loop) is in the outside of shuttle body, as shown in Figure 4.It addition, at the steel wire fixing an arc close to yarn guiding port place, the two ends of this curved wire are symmetrical about yarn guiding port, and are fixed on shuttle body, this steel wire is wherein equipped with a removable yarn-guiding loop.When the work of this shuttle, weft yarn unwinds from spool 5, then first passes around the weft tension control spring with yarn-guiding loop on the left of yarn guiding port, secondly with the weft tension control spring of yarn-guiding loop on the right side of yarn guiding port, then pass through the yarn-guiding loop close to yarn guiding port place, eventually pass through yarn guiding port.It is respectively mounted Magnet, it is therefore an objective to the spool 5 when slowing down wefting insertion excessively unwinds below the bayonet lock 4 at spool 5 two ends.This device is simply easily processed, and yarn, under the weft tension control spring effect with yarn-guiding loop of the two ends, yarn guiding port left and right, possesses certain tension force, do not have lax phenomenon.
Certain above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All modifications done according to the spirit of main technical schemes of the present invention, all should be encompassed within protection scope of the present invention.
