Meanwhile, weaving process, along with beating motion, makes the fluctuation of warp thread larger, looms vibration is larger, this broadwise exacerbating cloth width is shunk and occurs the loose and loose warp phenomenon of cloth cover, for the short fiber warp thread without starching (powerful weak), there is the deficiency that cracked ends rate is high.
[summary of the invention]
The object of the present invention is to provide the wide cloth support arrangement of the full width of the large jacquard weaving machine of a kind of arrow shaft, this full width wide cloth support arrangement adapts to the large jacquard weaving machine of arrow shaft completely and adopts the short fiber warp thread without starching to carry out high-efficiency weaving, when it can slow down harness motion top line to the lifting force of view picture fabric, lower layer warp yarns to the tension force slowing down warp tension when the downforce of view picture fabric and beating motion and bear, ensure that the uniformity consistency that view picture fabric tension continues, cloth width broadwise shrinkage is little, and warp thread cracked ends rate is low.
For solving the problems of the technologies described above, the invention provides following technical scheme:
The wide cloth support arrangement of full width of the large jacquard weaving machine of arrow shaft, comprise the semicircular cover plate of monolithic, the semicircular cloth supporting plate of monolithic and the wall scroll screw rod be movably set between cover plate and cloth supporting plate, described screw rod is formed with the equal and continuous thread that the hand of spiral is contrary of two pitch tilted towards rod end separately by this bar centre position, form fabric between cover forward end and cloth supporting plate front end to import and export, fabric is continued to be interwoven by top line and lower layer warp yarns, motion is weaved along with the large jacquard weaving machine of arrow shaft, the fabric that fell place is formed continues shift-in cloth supporting plate front end, and then wrap up screw rod under mobile status and shift out cover forward end, to be close to lid surface by the wide cloth support arrangement of full width of the large jacquard weaving machine of this arrow shaft of rolling off, described screw rod is circular, the fabric at parcel screw rod place is in open circle, movable space of installing screw rod is supplied to be a untight circle between cover plate and cloth supporting plate, this untight circle roughly constitutes three concentric circles differed in size with the fabric and screw rod wrapping up screw rod place.
Compared with prior art, tool has the following advantages and beneficial effect in the present invention:
1, revolutionize an existing left side, right cloth support structure is only left to cloth width, right both sides are played and limited are propped up binding mode, as overhead is left, the downward suppression of right cloth support to cloth width both sides, such as underneath type is left again, the upwards suppression of right cloth support to cloth width both sides, the substitute is view picture fabric parcel screw rod, and screw rod is constrained between cover plate and cloth supporting plate effectively, thus, when jacquard weaving is when shedding amount is large, this device can slow down the lifting force of top line to view picture cloth cover, thus it is crooked to avoid warp, loose warp, cloth cover relaxation, hair warp caused by sword head bottom friction loose warp, cracked ends chance is little, and when jacquard weaving is when shedding amount is little, slow down the downforce of lower layer warp yarns to view picture cloth cover, the cracked ends phenomenon causing caused by cloth cover tension to avoid average tension on warp.
2, screw surface has the equal and continuous thread that the hand of spiral is contrary of two pitch tilted towards rod end separately, ensure that the uniformity consistency that view picture fabric tension continues, the effect that cloth width broadwise is shunk can be avoided completely, and then, fabric forms open circle at screw rod place, screw rod is solid to cloth width parcel, grips cornerite large.
3, because screw rod is upper, there is between lower cover certain free gap, in process along with loom beating-up motion, the fabric being wrapped in screw rod place can drive screw rod to move back and forth as trace together, when slay is to moving cloth fell beating-up, fabric moves to fell place, and when slay moves apart fell, fabric batches action smoothly, fabric and beating-up is made to realize relative motion thus, to slow down the tension force that the process warp tension of beating up bears, when the large jacquard weaving machine of arrow shaft adopting the short fiber warp thread (this especially weak through yarn material brute force) without starching weave, show as the advantage that cracked ends rate is low, short fiber warp thread (as cotton warp) without starching can reduce by one sizing preparatory process, and weave smoothly.
