The specific embodiment
Like Fig. 5,6, shown in 7, the first weft yarn extending apparatus of the utility model 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.
