[0019] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0020] refer to Figure 1-3 The embodiment of the utility model discloses a yarn rack for feeding yarn of a circular knitting machine, comprising a connecting rod 2, on which a mounting rod 5 for placing a yarn tube 6 is arranged.

[0021] like Figure 1 As shown, the left end of the connecting rod 2 is fixedly connected to the yarn loop of the circular knitting machine 1, and the mounting rod 5 is arranged on the right end of the circular knitting machine 1. A wire guide rod 3 is arranged on the connecting rod 2, and the yarn tube 6 is rotatably arranged on the connecting rod 2. After being pulled by the wire guide rod 3, it passes through the yarn feeder 4 on the circular knitting machine 1.

[0022] The yarn guide rod 3 is arranged in the vertical direction to adjust the direction of the yarn so that the yarn enters the yarn feeder 4 in a predetermined direction.

[0023] like Figure 2 As shown, the yarn tube 6 is sleeved on the mounting rod 5, a connecting portion 7 is fixedly provided on the connecting rod 2, a magnet 8 is fixedly provided on the connecting portion 7, an iron sheet 9 is provided on the mounting rod 5, and the magnet 8 can magnetically attract the iron sheet 9. When the magnet 8 magnetically attracts the iron sheet 9, the mounting rod 5 and the yarn tube 6 are connected to the connecting rod 2.

[0024] A support plate 16 is disposed at the lower end of the mounting rod 5 , and the upper end surface of the support plate 16 can abut against the lower end surface of the yarn drum 6 to prevent the yarn drum 6 from falling off the mounting rod 5 downward.

[0025] When the mounting rod 5 needs to be replaced, one only needs to pull the mounting rod 5 downward forcefully, pull out the old yarn tube 6 through the upper end of the mounting rod 5 (the outer diameter of the iron sheet 9 is set to be smaller than the inner diameter of the through hole of the yarn tube 6), and then replace it with the new yarn tube 6 to complete the replacement of the yarn tube 6.

[0026] To avoid unraveling of the yarn, refer to Figure 2 The connecting portion 7 is rotatably provided with a linkage rod 14 through a second bearing 13, and the linkage rod 14 is coaxially fixed with a friction portion 15, refer to Figure 3 The connecting rod 2 is provided with a sliding block 26 , and the sliding block 26 is provided with a friction belt 19 . The friction belt 19 is wound around the outer peripheral side of the friction part 15 .

[0027] Specifically, springs 20 are fixedly provided at both ends of the friction belt 19, and second hooks 22 are fixedly provided at the free ends of the springs 20. Two first hooks 21 are fixedly provided on the sliding block 26. The friction belt 19 can be installed on the sliding block 26 by hooking the two second hooks 22 on the corresponding first hooks 21 respectively.

[0028] A spline shaft 11 is fixedly disposed on the upper end of the mounting rod 5 . The spline shaft 11 extends upward from the upper end surface of the mounting rod 5 . The linkage rod 14 is provided with a spline hole 12 for the spline shaft 11 to penetrate therein.

[0029] The mounting rod 5 is rotatably connected to the iron sheet 9 via a first bearing 10 .

[0030] A plurality of columns 17 are fixedly arranged on the upper end surface of the support plate 16 and extend upward. A plurality of embedding holes are provided on the yarn drum 6 for the columns 17 to penetrate therein, so that the yarn drum 6, the mounting rod 5 and the linkage rod 14 can realize synchronous rotation.

[0031] When the yarn feeder 4 pulls the yarn, the yarn tube 6, the mounting rod 5 and the linkage rod 14 rotate simultaneously, and the friction belt 19 generates a friction force on the friction part 15, thereby generating a damping to prevent the yarn tube 6 from rotating randomly and causing the yarn to be scattered, and to prevent the individual yarns from being entangled after being scattered.

[0032] In order to facilitate the adjustment of the resistance of the friction part 15, the sliding block 26 is slidably arranged on the connecting rod 2, and a dovetail slide rail (not shown in the figure) is fixedly arranged on the upper end surface of the connecting rod 2. The sliding block 26 is provided with a dovetail slide groove (not shown in the figure) for the dovetail slide rail to slide inside. The connecting rod 2 is rotatably provided with a shaft rod 24 through the third bearing 23. One end of the shaft rod 24 is a threaded section, and the sliding block 26 is provided with a threaded through hole 25 for the threaded section of the shaft rod 24 to pass through. When the shaft rod 24 is rotated, the pressure between the friction belt 19 and the friction part 15 can be adjusted, and the damping size of the linkage rod 14 when rotating is changed.

[0033] In order to adapt to the yarn bobbins 6 of different heights, the lower end of the mounting rod 5 is threadedly sleeved with an adjusting nut 18, and the upper end surface of the adjusting nut 18 can abut against the lower end surface of the supporting plate 16. The lower end of the mounting rod 5 is an elliptical column, and the supporting plate 16 is provided with an elliptical through hole for the lower end of the mounting rod 5 to pass through, so as to ensure that the supporting plate 16 and the mounting rod 5 rotate synchronously.

[0034] The height of the support plate 16 is adjusted by adjusting the nut 18, thereby adjusting the distance from the upper end surface of the yarn bobbin 6 to the lower end surface of the connecting rod 2 to adapt to yarn bobbins 6 of different heights and avoid the yarn bobbin 6 jumping upward when the machine is running due to the height of the yarn bobbin 6 being too low and the distance between the upper end surface of the yarn bobbin 6 and the lower end surface of the connecting rod 2 being too large, so that the yarn bobbin 6 is separated from the column 17 due to jumping when the machine is running.

[0035] The modifications and changes made using this creation are all within the patent scope claimed by this creation, and are not limited to those disclosed in the embodiments.
