The specific embodiment
Like Fig. 5,6, shown in 7, first weft yarn extending apparatus of the present invention comprises slay 1, connecting rod 8, is fixed with guide rod guide holder 7 and guide rail bearing 16 on the said connecting rod 8; Said guide rod guide holder 7 is provided with guide rod 6, and said guide rod 6 can slide on guide rod guide holder 7; Said guide rod 6 stretches out guide rod guide holder 7 one ends and is provided with spacing connecting plate 9, and the other end of said guide rod 6 is fixed with master slider 3, between master slider 3 and guide rod guide holder 7, is provided with back-moving spring 4 on the said guide rod 6; Be fixed with guide rail 11 on the said guide rail bearing 16, said guide rail 11 is provided with time slide block 15, also is fixed with cylinder block 12 on said the slide block 15, is fixed with cylinder 13 on the said cylinder block 12, and the piston rod free end of said cylinder 13 is connected with tuck 14; Also be connected with pull bar 10 on the said cylinder block 12, the other end of said pull bar 10 is connected on the master slider 3.
Said guide rod 6 is two.The outside of said master slider 3 is surrounded by rubber blanket 2, and said pull bar 10 is hinged on master slider 3.Said cylinder block 12 is the U font of a side opening, and said cylinder 13 is fixed on the top of cylinder block 12, and said tuck 14 is positioned at the opening part of cylinder block 12.The other end of said guide rod 6 is provided with screw thread, and the both sides of said spacing connecting plate 9 respectively are provided with a nut, fixes said spacing connecting plate 9, and can adjust the position of spacing connecting plate 9.The adjustable length of said pull bar 10, two ends respectively are provided with an oscillating bearing.The cross section of said connecting rod 8 is trapezoidal.Be provided with sliding bearing 5 between said guide rod and the guide rod guide holder.The piston rod free end of said cylinder 13 is fixed on the tuck seat 17, and said tuck 14 also is fixed on the tuck seat 17.
The operation principle of first weft yarn extending apparatus of the present invention is following:
When slay 1 moves behind machine; Master slider 3 and guide rod 6 in the hole on guide rod guide holder 7 under the driving of back-moving spring 4 also to the machine rear to motion; Through pull bar 10 haul time slide block 15 along guide rail 11 near fabric and machine rear to mobile; Make tuck 14 on time slide block 15 arrive fabric edges and squeezed into the weft yarn rear side (seeing accompanying drawing 2) of fell, and under the effect of cylinder 13, move downward and stumble weft yarn (seeing accompanying drawing 3); When the next round wefting insertion finishes to beat up once more; Slay 1 moves towards master slider 3 directions, up to contacting with master slider 3, and pushing away master slider 3 and guide rod 6 to machine the place ahead to moving and with back-moving spring 4 compressions; Pushing away time slide block 15 through pull bar 10 moves before machine and away from the fabric direction along guide rail 11; Tuck 14 is moved weft yarn unnecessary in the shed open to the shed open outside (seeing accompanying drawing 4), and the first weft thread that the back of beating up is introduced is open and flat, stretch, unfolded, reaches the purpose that improves fabric quality; Tuck 14 is mentioned the extreme higher position under the effect of cylinder 13 then, accomplishes one time stretching.
When fabric width changes; The length difference of first latitude and other latitude also can change to some extent; Adjust the relative position of spacing connecting plate 9 and guide rod 6 with the nut on spacing connecting plate 9 two sides, change guide rod 6 extension elongation behind machine, thereby change effective traverse of master slider 3; Adjust the length of pull bar 10 simultaneously, change requirement span to satisfy fabric width.
