[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-3 A replaceable yarn guide for textile machinery includes a main body 1. A mounting frame 2 is fixedly connected to the top of the main body 1. A sliding opening 3 is provided at the top of the main body 1. A movable frame 4 that can move left and right is slidably connected to the sliding opening 3. A clamping cavity 5 is provided inside the movable frame 4. A clamping structure 6 is provided inside the clamping cavity 5. The clamping structure 6 clamps a first bearing 7. A rotating shaft 8 is engaged with the inner wall of the first bearing 7. A yarn guide roller 9 is sleeved on the outer wall of the rotating shaft 8.

[0021] It should be noted that the yarn guide roller 9, servo motor 10, first bearing 7, and second bearing 13 are existing technologies. The specific model and specifications to be used need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technologies in this field, so it will not be elaborated here.

[0022] Furthermore, a servo motor 10 is installed on one side of the inner wall of the slide 3, and a lead screw 11 is fixedly connected to the output end of the servo motor 10. A slide rod 12 is fixedly connected to the inner wall of the slide 3.

[0023] In this process, by starting the servo motor 10, the servo motor 10 drives the lead screw 11 to rotate, and the lead screw 11 drives the moving frame 4 to slide left and right on the inner wall of the slide 3, making the disassembly of the moving frame 4 easier.

[0024] Furthermore, the slide bar 12 is positioned above the lead screw 11, the lead screw 11 is threadedly connected to the movable frame 4, and the slide bar 12 is slidably connected to the movable frame 4.

[0025] Among them, under the action of the slide bar 12, the movable frame 4 can move more stably within the slide opening 3.

[0026] Furthermore, a second bearing 13 is snapped into the inner wall of the mounting bracket 2, and the inner wall of the second bearing 13 is fixedly connected to the rotating shaft 8.

[0027] The second bearing 13 can be removed along with the rotating shaft 8, which can prevent damage to the second bearing 13 and the mounting bracket 2 when the rotating shaft 8 is removed.

[0028] Furthermore, the clamping structure 6 includes a bidirectional lead screw 14, a clamping seat 15, an external rotating handle 16, a rectangular slot 17, and a pin 18.
