The specific embodiment
Shown in Fig. 5,6,7, first weft yarn extending apparatus of the present invention comprises slay 1, connecting rod 8, and guide rod guide holder 7 and guide rail bearing 16 are fixedly arranged on the described connecting rod 8; Described guide rod guide holder 7 is provided with guide rod 6, and described guide rod 6 can slide at guide rod guide holder 7; Described 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 described guide rod 6 fixedly has master slider 3, is provided with back-moving spring 4 on the described guide rod 6 between master slider 3 and guide rod guide holder 7; On the described guide rail bearing 16 guide rail 11 is arranged fixedly, described guide rail 11 is provided with time slide block 15, and cylinder block 12 is also fixedly arranged on described the slide block 15, on the described cylinder block 12 cylinder 13 is arranged fixedly, and the piston rod free end of described cylinder 13 is connected with tuck 14; Also be connected with pull bar 10 on the described cylinder block 12, the other end of described pull bar 10 is connected on the master slider 3.
Described guide rod 6 is two.The outside of described master slider 3 is surrounded by rubber blanket 2, and described pull bar 10 is hinged on master slider 3.Described cylinder block 12 is the U font of a side opening, and described cylinder 13 is fixed on the top of cylinder block 12, and described tuck 14 is positioned at the opening part of cylinder block 12.The other end of described guide rod 6 is provided with screw thread, and the both sides of described spacing connecting plate 9 respectively are provided with a nut, fixes described spacing connecting plate 9, and can adjust the position of spacing connecting plate 9.The adjustable length of described pull bar 10, two ends respectively are provided with an oscillating bearing.The cross section of described connecting rod 8 is trapezoidal.Be provided with sliding bearing 5 between described guide rod and the guide rod guide holder.The piston rod free end of described cylinder 13 is fixed on the tuck seat 17, and described tuck 14 also is fixed on the tuck seat 17.
The operation principle of first weft yarn extending apparatus of the present invention is as follows:
When slay 1 moves behind the 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, by pull bar 10 haul time slide block 15 along guide rail 11 near fabric and machine rear to movement, 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 again, 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 mobile 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), the first weft thread that the back of beating up is introduced is open and flat, stretch, unfolded, reach the purpose that improves fabric quality, tuck 14 is mentioned the extreme higher position under the effect of cylinder 13 then, finishes stretching one time.
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 the machine, thereby change effective traverse of master slider 3, adjust the length of pull bar 10 simultaneously, to satisfy the fabric width variation to the requirement of span.
