Description
Technical field
The invention belongs to technical field of textile machine, be specifically related to a kind of weft insertion device of the Rapier looms for weaving two-layer fabric.
Background technology
The weft insertion device of Rapier looms from its literal lexical or textual analysis as can be known its function be to carry parallel (being the alleged wefting insertion of industry).The TECHNICAL INFORMATION SOURCES that in disclosed Chinese patent literature, is no lack of the weft insertion device of Rapier looms, slightly with exemplify such as " the sword belt guide that is used for the sword belt loom " that " the sword belt driving mechanism that is used for Rapier looms ", the CN200985409Y that Granted publication CN1779008B recommends provides and " electronic weft insertion system of rapier loom " of CN201785584U introduction, etc.
Be not limited to the above-mentioned patent documentation that exemplifies and all include arrow shaft and sword transmission wheel, and fit system and the structure of arrow shaft and sword transmission wheel all are identical.Specifically, sword transmission wheel do clockwise with counterclockwise checker motion under, make the arrow shaft reciprocating motion and finish wefting insertion, in addition, although above-mentioned patent is referred to as sword belt with arrow shaft, played in fact the effect of arrow shaft.
As is known in the industry, arrow shaft must have the physical property of tempering toughness with gentleness, otherwise can't finish the wefting insertion action, and when sword transmission wheel was done counterclockwise to turn round, arrow shaft was just moved towards the direction that deviates from Rapier looms, and vice versa.But when arrow shaft is moved towards the direction that deviates from Rapier looms, when namely the sword head of arrow shaft one end moves towards the direction that deviates from wefting insertion, then the other end of arrow shaft (with respect to the end with sword head) stretches just as tediously long tail, thereby requires in the on-the-spot space that is enough to for the arrow shaft motion of stretching that keeps of the fabric knitting of Rapier looms.So cause following technical problem: one, the space that takies Workplace is large, and consists of the impact of interference capability to the pedestrian; Its two, as aforementioned, because arrow shaft need possess the rigidity of wefting insertion technological requirement, therefore easily crack and even rupture; Its three, arrow shaft is short service life, changes frequent and affects the operating efficiency of loom; Its four, lose safety, because when the aforementioned other end of arrow shaft stretches just as tediously long tail, have the anxiety that injures the pedestrian.
In order to eliminate aforementioned drawback, industry is poured into mentality of designing the material of arrow shaft untiringly at present, phase is got the service life of proper extension arrow shaft, but can not solve first in aforementioned 4 shortcomings, the 4th shortcoming, namely take the Workplace space and people around or object are produced interference effect.
Chinese invention patent application publication No. CN102912532A(is used for the weft insertion device of the Rapier looms of braiding two-layer fabric) and the weft insertion device of CN102912533A(Rapier looms) technical problem of aforementioned four aspects all can comprehensively be solved, but still there is following logical fraud in these two patent application schemes: one, owing to needing to use two sword belts, therefore draw the sword wheel and have two, thereby cause complex structure, and the steady effect of motion is difficult to guarantee; Its two all have a pair ofly owing to drawing sword wheel and sword belt, therefore be used for ordering about the power that draws the power transmission box that the sword wheel moves relatively large, thereby be unfavorable for saves energy consumption.In view of this, still have improved necessity, for this reason, the applicant has carried out unremitting exploration and experiment, has finally found the way that is remedied this shortcoming, and technical scheme described below is based on producing under this prerequisite.
