[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Specific examples are given below.
[0024] like Figures 1 to 4As shown, an adjustable yarn guiding mechanism of a flat knitting machine described in an embodiment of the utility model comprises a pair of fixed plates 1; a pair of inner side walls of the fixed plates 1 are connected to a first roller 11 for rotation together; a pair of inner side walls of the fixed plates 1 are connected to a second roller 12 for rotation together; a pair of side walls of the fixed plates 1 are each provided with a first slide groove 13; a slide rod 14 is slidably connected to the inner side wall of the first slide groove 13; a third roller 15 is rotatably connected to the middle of the slide rod 14; a connecting plate 16 is fixedly connected to the end of the slide rod 14; a hole is provided on the connecting plate 16; a plurality of fixing holes 17 are provided on the side wall of the fixed plate 1; the holes on the connecting plate 16 are aligned with the fixing holes 17; a fixing pin 18 is installed in the hole on the connecting plate 16; when working, the yarn is passed around the first roller 11, the second roller 12 and the third roller 15 respectively during spinning, and when the yarn descends The third roller 15 is then moved to a position where the yarn is pulled up and the yarn is pulled down and the yarn is pulled up ...
[0025] like Figure 3 As shown, the end of the fixed plate 1 is fixedly connected to a fixed frame 2; the inner side wall of the fixed frame 2 is provided with a second slide groove 21; a slide plate 22 is slidably connected in the second slide groove 21; a hole is provided on the slide plate 22; when working, the yarn passes through the hole on the slide plate 22 during spinning, and then passes around the first roller 11, the second roller 12 and the third roller 15. During the decircling process, the yarn will swing on the coil, and at this time, the yarn passes through the slide plate 22, which can drive the slide plate 22 to slide in the second slide groove 21 during the swinging, and the yarn can be limited and protected at this time. In this step, the fixed frame 2 is set to connect the slide plate 22, so that the yarn can be limited and protected when it swings, which can reduce the situation where the yarn swings too much and falls off the surface of the first roller 11 and gets entangled, so as to improve the stability of spinning.
[0026] like Figure 4As shown, a pair of fixed rods 3 are fixedly connected to one end of the fixed plate 1 away from the fixed frame 2; the end of the fixed rod 3 is rotatably connected to the fourth roller 31; during operation, when the yarn passes through the second roller 12, the yarn is passed between the fourth rollers 31 on both sides. At this time, the fourth roller 31 clamps the yarn and rotates as the yarn moves during the descent of the yarn. In this step, by setting the fixed rod 3 to connect the fourth roller 31, the yarn can be clamped after passing through the second roller 12 to improve the stability of the yarn when it moves downward.
[0027] like Figure 4 As shown, a pair of side walls of the fixed rods 3 are fixedly connected to a fixed ring 4; the inner wall of the fixed ring 4 is fixedly connected to a plurality of bristles 41; when working, before the yarn passes through the fourth rollers 31 on both sides, the yarn passes through the fixed ring 4, and when the yarn moves continuously, it will contact with the bristles 41, and the bristles 41 can clean the surface of the yarn. In this step, by setting a fixed ring 4 to connect the bristles 41, the surface of the yarn can be cleaned when it moves, so as to reduce the attachment of debris such as fluff remaining on the surface of the yarn, so as to improve the quality of spinning.
[0028] like Figure 3 As shown, a pair of fifth rollers 5 are rotatably connected to the inner wall of the fixed plate 1; the pair of fifth rollers 5 are aligned with the first roller 11 and the second roller 12 respectively; during operation, when the yarn moves on the surface of the first roller 11 and the second roller 12, the fifth roller 5 presses the yarn from one side of the first roller 11 and the second roller 12, and drives the fifth roller 5 to rotate simultaneously when the yarn moves. In this step, by setting the fifth roller 5 to press the yarn from one side of the first roller 11 and the second roller 12, the yarn can be reduced from coming out when moving on the surface of the first roller 11 and the second roller 12, so as to improve the stability of the yarn when moving.
[0029] like Figure 3 As shown, the side wall of the skateboard 22 is fixedly connected with a protective cover 6; the protective cover 6 is aligned with the hole on the skateboard 22; during operation, when the yarn passes through the hole on the skateboard 22, the protective cover 6 is aligned with the hole on the skateboard 22 so that the yarn will pass through the protective cover 6, and when the yarn swings, the protective cover 6 is a flexible material and will drive the protective cover 6 to swing. In this step, by setting the protective cover 6 to connect the hole on the skateboard 22, the wear between the yarn and the skateboard 22 can be reduced when the yarn passes through and swings, resulting in the yarn breaking or fluffing, so as to improve the stability during routing.
[0030] like Figure 4As shown, the side wall of the fifth roller 5 is fixedly connected with a rubber pad 7; when working, when the fifth roller 5 presses the yarn onto the first roller 11 and the second roller 12, the rubber pad 7 contacts the yarn to increase friction and reduce wear. In this step, the rubber pad 7 is connected to the fifth roller 5 to reduce the wear between the fifth roller 5 and the yarn.
[0031] Working principle: during spinning, the yarn is passed around the first roller 11, the second roller 12 and the third roller 15 respectively. When the yarn is relatively loose during the descent of the yarn, the fixing pin 18 can be taken out from the hole on the connecting plate 16, and then the sliding bar 14 is made to slide in the first slide groove 13 to drive the third roller 15 to move. At this time, the position of the third roller 15 can be changed so that the third roller 15 is not on the same horizontal line as the first roller 11 and the second roller 12, and then the fixing pin 18 is inserted into the hole on the connecting plate 16. At this time, the yarn can be lifted up to increase its tension and be tightly attached to the surfaces of the first roller 11, the second roller 12 and the third roller 15. During spinning, the yarn is passed through the hole on the slide plate 22, and then passed around the first roller 11, the second roller 12 and the third roller 15. During the de-looping process, the yarn will swing on the coil, and at this time, the yarn passing through the slide plate 22 can drive the slide plate 22 to slide in the second slide groove 21 when swinging, and the yarn can be limited and protected at this time. When the yarn passes through the second roller 12, the yarn passes between the fourth rollers 31 on both sides. At this time, the fourth roller 31 clamps the yarn and rotates as the yarn moves during the descent. Before the yarn passes through the fourth rollers 31 on both sides, the yarn passes through the fixed ring 4. When the yarn moves continuously, it will contact the bristles 41. At this time, the bristles 41 can clean the surface of the yarn. When the yarn moves on the surface of the first roller 11 and the second roller 12, the fifth roller 5 The first roller 11 and the second roller 12 press the yarn on one side, and when the yarn moves, it will drive the fifth roller 5 to rotate at the same time. When the yarn passes through the hole on the slide plate 22, the protective cover 6 is aligned with the hole of the slide plate 22, which will allow the yarn to pass through the protective cover 6. When the yarn swings, the protective cover 6 is a flexible material that will drive the protective cover 6 to swing. When the fifth roller 5 presses the yarn onto the first roller 11 and the second roller 12, the rubber pad 7 contacts the yarn to increase friction and reduce wear.
