In view of this, the inventor of the present application provides a wear-resistant flipping device for the yarn guide plate of a ring spinning machine, which can prevent wear on the outer surface of the yarn guide rod and ensure the accuracy and stability of the flipping movement of the yarn guide plate.
[0024] Example 1

[0027] Based on the above embodiment, by respectively arranging the first bushing 24 and the second bushing 32 in the first mounting hole 23 and the second mounting hole 31, the yarn guide rod 1 is prevented from wearing against the first mounting hole 23 and the second mounting hole 31 during rotation; the two cylinder fixing brackets 2 are connected to form an integral whole, thereby improving the overall stability of the two flipping wear-resistant devices.
[0028] In this embodiment, if Figure 3 As shown, one end of the connecting plate 22 is rotatably connected to the output end of the cylinder 21, and the other end of the connecting plate 22 is penetrated by a fastening hole 26. The connecting plate 22 is sleeved on the yarn guide rod 1 through the fastening hole 26. A fastening groove 27 is provided on one side of the fastening hole 26.

[0029] Based on the above embodiment, when the cylinder 21 is connected to the yarn guide rod 1 through the connecting plate 22, the yarn guide rod 1 is placed inside the fastening hole 26, and the size of the fastening groove 27 is reduced by the fastening screw 28, and the fastening hole 26 is also reduced accordingly, thereby tightening the yarn guide rod 1. At this time, the output end of the cylinder 21 is extended, which will push the connecting plate 22 to rotate around the yarn guide rod 1. At the same time, the connecting plate 22 drives the yarn guide rod 1 to rotate in the first shaft liner 24 and the second shaft liner 32.
[0030] In this embodiment, the two ends of the yarn guide rod 1 are respectively arranged in the first bushing 24 and the second bushing 32, and a flange end face is provided on one side of the first bushing 24 and the second bushing 32. The flange end face of the first bushing 24 fits with the side wall of the cylinder fixing bracket 2, and the flange end face of the second bushing 32 fits with the side wall of the sensor bracket 3.

At this time, the flange end face on one side of the first bushing 24 and the locking ring 25 limit the first bushing 24 to prevent the first bushing 24 from moving out from between the first mounting hole 23 on the cylinder fixing bracket 2 and the yarn guide rod 1; the support rod tightening ring 33, the second bushing 32 and the sensor bracket 3 are sequentially mounted on the yarn guide rod 1. At this time, the flange end face on one side of the second bushing 32 and the support rod tightening ring 33 limit the second bushing 32 to prevent the second bushing 32 from moving out from between the second mounting hole 31 on the sensor bracket 3 and the yarn guide rod 1.
[0033] In this embodiment, if Figure 5 As shown, the first bushing 24 and the second bushing 32 are both complete circular rings, the thickness of the first bushing 24 and the second bushing 32 are both 2mm-5mm, and the diameter of the flange end surface of the first bushing 24 and the second bushing 32 are both 25mm-38mm.
[0034] Based on the above embodiment, when the first shaft liner 24 is severely worn, it is necessary to remove the connecting plate 22, the locking ring 25, the cylinder fixing bracket 2 and the first shaft liner 24 in sequence, and then replace the new first shaft liner 24; when the second shaft liner 32 is severely worn, the sensor bracket 3 and the second shaft liner 32 are removed in sequence, and then replace the new second shaft liner 32.

[0037] Based on the above embodiment, when the first shaft liner 24 is severely worn, the locking ring 25 is moved to separate it from the flange end face of the first shaft liner 24. At this time, the first shaft liner 24 can be taken out from between the first mounting hole 23, and the first shaft liner 24 is removed from the yarn guide rod 1 through the opening on the first shaft liner 24. The new first shaft liner 24 is sleeved on the yarn guide rod 1 through the opening thereon, and the replaced first shaft liner 24 is moved between the first mounting hole 23 and the yarn guide rod 1, and then the locking ring 25 is moved to fit with the flange end face of the first shaft liner 24; when the second shaft liner 32 is severely worn, the support rod tightening ring 33 is separated from the flange end face of the second shaft liner 32, the second shaft liner 32 is taken out, and a new second shaft liner 32 is replaced.
[0038] Example 3
