DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 6 As shown, a line selection mechanism of a warp knitting machine described in the utility model comprises a bottom plate 1, a pair of side plates 2 are fixedly connected to the top wall of the bottom plate 1, and the two side plates 2 are horizontally symmetrical about the bottom plate 1; a support plate 3 is fixedly connected to the top wall of the side plate 2; a rotating shaft 4 is rotatably connected to the side wall of the support plate 3; a mounting circular plate 5 is fixedly connected to the end of the rotating shaft 4; a fixed plate 6 is fixedly connected to the side wall of the support plate 3; a rotating disk 7 is provided on the side wall of the fixed plate 6, and the first rotating disk 7 is connected to the rotating shaft 4 through a transmission assembly; a group of evenly distributed pay-off rollers 8 are fixedly connected to the side wall of the mounting circular plate 5; a group of yarn wheels 9 are rotatably connected to the outer circular walls of a group of the pay-off rollers 8; a wire roller 10 is rotatably connected between the side walls of a pair of the side plates 2; During operation, different yarns are placed on the yarn wheels 9 on different pay-off rollers 8 in turn, and the yarns are introduced into the warp knitting machine through the guide roller 10 below for weaving. When different yarns need to be replaced, the turntable 7 is rotated, and the rotation of the turntable 7 drives the rotating shaft 4 to rotate through the transmission assembly. The rotation of the rotating shaft 4 drives the mounting circular plate 5 to rotate, and the mounting circular plate 5 drives the pay-off roller 8 to rotate, so that the pay-off rollers 8 with different yarns placed thereon rotate close to the guide roller 10. The above technical scheme well avoids the problem in the prior art that when different yarns need to be replaced during use of the existing warp knitting machine, the line rollers need to be disassembled and then different yarn line rollers need to be reinstalled, which is a cumbersome operation and inefficient.

[0024] The transmission assembly includes a rotating rod 11, the side wall of the support plate 3 is rotatably connected to the rotating rod 11, and one end of the rotating rod 11 passes through the support plate 3 and is fixedly connected to the end of the rotating shaft 4; the other end of the rotating rod 11 is fixedly connected to a worm wheel 12; the side wall of the fixed plate 6 is rotatably connected to a worm 13, and the worm 13 is meshed with the worm wheel 12, and the other end of the worm 13 passes through the fixed plate 6 and is fixedly connected to the end of the turntable 7; when working, by rotating the turntable 7, the rotation of the turntable 7 drives the worm 13 to rotate, the rotation of the worm 13 drives the worm wheel 12 to rotate, the rotation of the worm wheel 12 drives the rotating rod 11 to rotate, and the rotation of the rotating rod 11 drives the rotating shaft 4 to rotate.

[0025] A group of mounting plates 14 are evenly fixed to the outer circular wall of the mounting circular plate 5, and the position of the mounting plates 14 corresponds to the pay-off roller 8; the side wall of the mounting plate 14 is rotatably connected to the first tensioning roller 15 through an elastic component; the side wall of the mounting plate 14 is rotatably connected to the second tensioning roller 16; when working, the yarn on the yarn wheel 9 passes through the first tensioning roller 15 and then is led out from the second tensioning roller 16, and the first tensioning roller 15 keeps the yarn in a taut state through the elastic component to avoid the situation where the yarn is too loose and different yarns are entangled with each other.

[0026] The elastic component includes a slide groove 17; the side wall of the mounting plate 14 is provided with a slide groove 17; a guide rod 18 is fixedly connected between the two inner side walls of the slide groove 17; the outer circular wall of the guide rod 18 is slidably connected with a first slider 19, and one end of the first slider 19 is rotatably connected to the end of the first tensioning roller 15; a spring 27 is fixedly connected to the side wall of the slide groove 17, and the other end of the spring 27 is fixedly connected to the side wall of the first slider 19, and the spring 27 is sleeved on the guide rod 18; during operation, when the yarn on the yarn wheel 9 passes through the first tensioning roller 15 and the second tensioning roller 16, the elastic force of the spring 27 in the slide groove 17 makes the yarn passing through the first tensioning roller 15 at the end of the slider in a stretched and straight state.

[0027] The side wall of the mounting plate 14 is provided with a mounting groove 20; the inner wall of the mounting groove 20 is rotatably connected with a threaded rod 21; the outer circular wall of the threaded rod 21 is threadedly connected with a second slider 22, and the second slider 22 slides horizontally in the mounting groove 20; the end of the second slider 22 is fixedly connected with a pressure block 23; the side wall of the pressure block 23 is provided with an arc groove 24; the other end of the threaded rod 21 is fixedly connected to a knob 25; when working, by turning the knob 25, the rotation of the knob 25 drives the threaded rod 21 to rotate, the rotation of the threaded rod 21 drives the second slider 22 to move, and the movement of the second slider 22 drives the pressure block 23 to press the second tensioning roller 16, thereby fixing the yarn on the second tensioning roller 16 to avoid affecting the yarn on the working yarn wheel 9.

[0028] The inner circular wall of the arc groove 24 is fixedly connected with a non-slip soft pad 26 . During operation, the anti-slip soft pad 26 is fixedly connected with the inner circular wall of the arc groove 24 , so that the fixation is more firm and the fixing effect is better.

[0029] Working principle: by placing different yarns on the yarn wheel 9 on different pay-off rollers 8 in turn, the yarn is introduced into the warp knitting machine through the guide roller 10 below for weaving. When different yarns need to be replaced, by rotating the turntable 7, the rotation of the turntable 7 drives the worm 13 to rotate, the rotation of the worm 13 drives the worm gear 12 to rotate, the rotation of the worm gear 12 drives the rotating rod 11 to rotate, the rotation of the rotating rod 11 drives the rotating shaft 4 to rotate, the rotation of the rotating shaft 4 drives the installation circular plate 5 to rotate, and the installation circular plate 5 drives the pay-off roller 8 to rotate, so that the pay-off rollers 8 with different yarns placed on them rotate close to the guide roller 10. The above technical scheme well avoids the problem in the prior art that when different yarns need to be replaced during use of the existing warp knitting machine, the line rollers need to be disassembled and then different yarn line rollers need to be reinstalled. This method is complicated to operate and has the problem of low efficiency. When the yarn on the yarn wheel 9 passes through the first tensioning roller 15 and the second tensioning roller 16, the elastic force of the spring 27 in the slide groove 17 makes the yarn passing through the first tensioning roller 15 at the end of the slider in a stretched state, thereby avoiding the situation where the yarn is too loose and different yarns are entangled with each other. By turning the knob 25, the rotation of the knob 25 drives the threaded rod 21 to rotate, and the rotation of the threaded rod 21 drives the second slider 22 to move. The movement of the second slider 22 drives the pressure block 23 to press the second tensioning roller 16, thereby fixing the yarn on the second tensioning roller 16 to avoid affecting the yarn on the working yarn wheel 9. The anti-skid pad 26 is fixedly connected to the inner circular wall of the arc groove 24, so that the fixation is more firm and the fixing effect is better.
