[0024] like Figure 6 As shown, the direction of the arrow in the figure represents the control direction of the yarn guide plate flipping mechanism 5. Since the two yarn guide plate flipping mechanisms 5 at the rear and middle of the extra-long ring spinning frame 6 are separately controlled by a control system 51 located at the rear of the ring spinning frame 6, the air source is respectively led from the rear air path plate to the rear and middle cylinders of the vehicle, resulting in the flipping actions of the rear and middle cannot be performed simultaneously, and the closer the installation position of the middle yarn guide plate flipping mechanism 5 is to the front of the vehicle, the easier it is to delay the flipping action, resulting in a longer rotation time of the yarn guide rod 21, and then a longer time for the yarn guide plate to complete the flipping action. When the air source pressure is insufficient, the flipping action of the yarn guide plate between the front and the middle of the vehicle cannot be completed. In view of this, the inventor of the present application provides a yarn guide plate flipping mechanism for a ring spinning frame, which can simultaneously control the yarn guide rods on one side of the ring spinning frame to rotate simultaneously, so that the yarn guide plates on one side of the spinning frame can be flipped simultaneously.
[0025] like Figure 1-5As shown, a ring spinning machine guide plate flipping mechanism is arranged in the middle of the super-long ring spinning machine, and the mechanism is controlled by a control system arranged at the rear of the super-long ring spinning machine, wherein the control system is not shown in the figure, and the mechanism includes: a frame assembly 1, a yarn guide rod assembly 2, a worm gear screw lifting assembly 3 and a flipping assembly 4.
[0026] Among them, Figure 1 As shown, the frame assembly 1 includes a middle wall panel 11 , the bottoms of the front and rear sides of the middle wall panel 11 are provided with supports 12 , and the middle parts of the front and rear sides of the middle wall panel 11 are provided with ribs 13 .
[0027] Based on the above embodiment, the worm gear screw lifting assembly 3 and the flip assembly 4 are supported by the middle wall plate 11 and the ribs 13 .
[0028] In this embodiment, if Figure 1-2 As shown, two yarn guide rod assemblies 2 are provided, and the two yarn guide rod assemblies 2 are respectively arranged above two dragon tendons 13, and each yarn guide rod assembly 2 includes a yarn guide rod 21, and a plurality of yarn guide plates 22 are evenly arranged on the yarn guide rod 21.

Since the second lifting screw 308 is connected to the steel collar seat, the second lifting screw 308 drives the steel collar seat to move up and down when it moves up and down.
[0036] In this embodiment, if Figure 1 , Figure 2 , Figure 5As shown, the flip assembly 4 is arranged between the two yarn guide rod assemblies 2, and includes a cylinder fixing bracket 41. The two ends of the cylinder fixing bracket 41 are respectively connected to the two yarn guide rods 21. Two cylinders 42 are symmetrically arranged on one side of the cylinder fixing bracket 41. The output end of each cylinder 42 is provided with a connecting plate 43, and the connecting plate 43 is connected to the yarn guide rod 21.
[0037] Among them, both ends of the cylinder fixing bracket 41 are provided with mounting holes 46, and the cylinder fixing bracket 41 is sleeved on the two yarn guide rods 21 through the two mounting holes 46; the cylinder 42 is rotatably connected with the connecting plate 43, and one end of the connecting plate 43 is penetrated by a fastening hole 44, and a fastening groove 45 is provided on one side of the fastening hole 44. The fastening groove 45 connects the fastening hole 44 with the outside world, and a screw is provided on one side of the fastening groove 45.

[0038] Based on the above embodiment, the connecting plate 43 is sleeved on the yarn guide rod 21 through the fastening hole 44, and then the size of the fastening groove 45 is reduced by screws. At this time, the connecting plate 43 tightens the yarn guide rod 21 through the fastening hole 44. When the cylinder 42 is extended or shortened, the connecting plate 43 is driven to rotate around the yarn guide rod 21. At the same time, the connecting plate 43 drives the yarn guide rod 21 to rotate in the mounting hole 46 through the fastening hole 44, thereby causing several yarn guide plates 22 on the yarn guide rod 21 to flip over.
[0039] The working principle of the utility model is as follows: when the super-long ring spinning machine is working, the control system arranged at the rear of the super-long ring spinning machine controls the motor to drive the transmission worm 305 to rotate, thereby driving the first rotating worm wheel 306 and the second rotating worm wheel 309 meshing with the transmission worm 305 to rotate, thereby driving the first lifting screw rod 302 and the second lifting screw rod 308 to move up and down, and the first lifting screw rod 302 and the second lifting screw rod 308 respectively drive the yarn guide rod 21 and the steel collar seat to move up and down, thereby making the yarn evenly wound on the bobbin;
[0040] When it is necessary to replace the yarn tube, the control system controls the motor to make the worm gear lifting assembly 3 move the yarn guide rod 21 to the specified position, and then controls the cylinder 42 of the flipping assembly 4 to extend, thereby controlling the yarn guide plate 22 to flip upward, so that the yarn tube will not collide with the yarn guide plate 22 when plugging and pulling out the yarn tube; when the yarn tube is replaced, the cylinder 42 is shortened, driving the connecting plate 43 to rotate around the yarn guide rod 21, and at the same time, the connecting plate 43 drives the yarn guide rod 21 to rotate in the mounting hole 46 through the fastening hole 44, thereby causing several yarn guide plates 22 on the yarn guide rod 21 to flip downward, and the transmission worm 305 is driven by the motor to move the first lifting screw rod 302 downward, thereby causing the yarn guide rod 21 to drive the yarn guide plate 22 to move down to the working position.
[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
