[0042] Reference Figure 1-Figure 5A twist reduction device for a circular knitting machine, comprising a carrier plate 1, a storage seat 2, a first untwisting rod 3 and a tension adjustment assembly 4, wherein a first yarn guide plate 11 and a second yarn guide plate 12 are respectively arranged on both sides of the carrier plate 1, the storage seat 2 is arranged on the carrier plate 1, and a receiving cavity 21 is provided on the storage seat 2, a plurality of first untwisting rods 3 are arranged and distributed in the receiving cavity 21 at intervals, and a placement area is formed between two adjacent groups of first untwisting rods 3, the first untwisting rods 3 are used to be wound with yarn, and the tension adjustment assembly 4 is used to adjust the tension of the yarn;

[0043] Several tension adjustment components 4 are provided and are distributed at intervals in the placement area. The tension adjustment components 4 include a screw component 41, a guide rod 42 and an adjustment plate 43. The screw component 41 and the guide rod 42 are respectively located on both sides of the accommodating chamber 21. The screw component 41 is connected to the bottom of the accommodating chamber 21 through a screw bearing seat 44. One end of the adjustment plate 43 is connected to the screw component 41. A connecting bearing 45 is installed at the connection between the adjustment plate 43 and the screw component 41, and the other end is connected to the guide rod 42. The adjustment plate 43 is arranged in an arc structure. By setting the connecting bearing 45, when the screw component 41 is rotated, the adjustment plate 43 can move in the vertical direction. The guide rod 42 is used to guide the movement of the adjustment plate 43, so that the adjustment plate 43 can move smoothly.

[0044] One end of the screw component 41 extends to the outside of the storage seat 2 and is installed with a hand wheel 411. Through the cooperation of the screw component 41 and the guide rod 42, the adjustment plate 43 and the first untwisting rod 3 are on the same horizontal plane to form a height difference. Through the setting of the hand wheel 411, the operator can rotate the screw component 41 by turning the hand wheel 411.

[0045] The first yarn guide plate 11 and the second yarn guide plate 12 are respectively provided with a first yarn hole 111 and a second yarn hole 121. A yarn movement area is formed by the first yarn hole 111, the second yarn hole 121 and the bottom of the adjustment plate 43. The yarn on the yarn tube enters the twist reduction device from the first yarn hole 111 and is drilled out from the second yarn hole 121. A guide plate 17 is also provided between the second yarn guide plate 12 and the storage seat 2. The guide plate 17 has a guide hole 171, which can guide the moving direction of the yarn.

[0046] Based on the above structure, one end of the yarn is passed through the first yarn hole 111, so that the yarn is located in the accommodating cavity 21 of the storage seat 2, and the yarn is wound around one or more groups of first untwisting rods 3 according to the type of yarn. When the yarn is being transported, it needs to move around the first untwisting rods 3 so that the fibers in the yarn are stretched to a certain extent, thereby gradually reducing the twist in the yarn, and the yarn is always located below the adjusting plate 43. The rotation of the screw rod component 41 can drive the adjusting plate 43 to move its position, so that the adjusting plate 43 squeezes the yarn and drives the yarn to move. The change in the position makes the heights of the yarn partially located at the first untwisting rod 3 and the yarn partially located at the adjusting plate 43 different, thereby realizing the tension adjustment of the yarn. Since there are several tension adjustment components 4, the yarn needs to contact different tension adjustment components 4 when moving from the storage seat 2 to the second yarn guide plate 12. The operator can adjust the heights of different adjustment plates 43 according to the actual situation, so as to be suitable for different types of yarns, thereby solving the problem that the tensions borne by different types of yarns are always at the same level, which affects the quality of the yarn.

[0047] In one embodiment, referring to Figure 1 , Figure 3 and Figure 4 , further comprising a yarn guide wheel 5 and a supporting member 6, the bearing plate 1 is provided with an annular groove 13, and the annular groove 13 is located between the second yarn guide plate 12 and the storage seat 2;

[0048] The yarn guide wheel 5 is connected to the annular groove 13 through the supporting component 6. When the yarn extends from the storage seat 2 to the second yarn guide plate 12, the yarn contacts the yarn guide wheel 5. The contact between the yarn guide wheel 5 and the yarn can guide the yarn. When the yarn needs to change direction, the yarn guide wheel 5 can help achieve smooth turning and avoid yarn knotting or entanglement.

[0049] In one embodiment, referring to Figure 1-Figure 3 , a track groove 14 is also provided on the carrier plate 1, and the track groove 14 is located on one side of the annular groove 13;

[0050] A support shaft 15 is provided at the center of the guide wheel 5 corresponding to the other side of the supporting plate 1, and an untwisting component 7 is rotatably provided on the support shaft 15. The untwisting component 7 includes a sleeve 71, a support plate 72 and a second untwisting rod 73. The sleeve 71 is rotatably provided on the support shaft 15, the support plate 72 is provided on the outer peripheral surface of the sleeve 71, and the second untwisting rod 73 is provided on the support plate 72. One end of the second untwisting rod 73 passes through the track groove 14 and extends to the outside of the supporting plate 1.

[0051] Based on the above structure, in order to further improve the twist reduction effect of the yarn, a second untwisting rod 73 entangled with the yarn is provided on the yarn guide wheel 5, so that the yarn can be untwisted at two different positions. Since the second untwisting rod 73 is installed on the support plate 72, and the support plate 72 is connected to the shaft sleeve 71 sleeved on the support shaft 15, the second untwisting rod 73 can be relatively moved along the track groove 14 by rotating the shaft sleeve 71. By changing the angular position of the second untwisting rod 73, the distance between the second untwisting rod 73 and the yarn guide wheel 5 can be changed, thereby adjusting the tension of the yarn.

[0052] In one embodiment, referring to Figure 1 and Figure 4 The supporting member 6 includes a fixed seat 61 and a movable rod 62. The fixed seat 61 is disposed on the annular groove 13. The fixed seat 61 has a receiving groove 611.

[0053] One end of the movable rod 62 is sleeved in the accommodating groove 611, and the other end of the movable rod 62 is connected to the bottom of the yarn guide wheel 5. As the position of the movable rod 62 in the accommodating groove 611 changes, the height of the yarn guide wheel 5 will change synchronously. The change in the height of the yarn guide wheel 5 will also change the tension of the yarn, so that it can be flexibly adjusted according to the type of yarn.

[0054] In one embodiment, referring to Figure 1 and Figure 3 The second untwisting rod 73 is provided with a yarn placing groove 731 with a threaded structure, and the yarn placing groove 731 is used to place the yarn so that the yarn can be wound around the second untwisting rod 73 along the angle of the yarn placing groove 731. At the same time, the yarn placing groove 731 can limit the yarn to avoid position deviation of the yarn during the transportation process.

[0055] In one embodiment, referring to Figure 1 and Figure 2 A mounting frame 16 is provided at one end of the carrying plate 1, and the twist reducing device can be stably installed above the circular knitting machine through the connection between the mounting frame 16 and the machine bracket.
