[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] Based on the existing existing technology, the yarn guide hook is installed by multiple sets of nut threads, which is cumbersome to operate, and the yarn guide hook is difficult to lock and easy to rotate. This embodiment provides a yarn guide hook fixing bracket for a twisting machine. Please refer to Figure 1-Figure 4 The embodiment provides a yarn guide hook fixing frame for a twisting machine, which can quickly and conveniently install the yarn guide hook and maintain the stability of the yarn guide hook. The yarn guide hook fixing frame for the twisting machine includes a U-shaped frame 2 installed on the top of a mounting column 1, a yarn guide hook 3 is installed above the U-shaped frame 2, an adjustment and fixing mechanism 4 for adjusting and fixing the angle of the yarn guide hook 3 is provided on the U-shaped frame 2, the yarn guide hook 3 is provided with a mounting mechanism 5 for facilitating the rapid installation of the yarn guide hook 3, and a rotating mechanism 6 for adjusting the traction position of the yarn guide hook 3 is provided at the bottom of the mounting column 1. The wire angle of the yarn guide hook 3 is adjusted and fixed by adjusting the fixing mechanism 4 to adapt to different spinning conditions. The yarn guide hook 3 is quickly installed by the mounting mechanism 5, which improves the efficiency of disassembly and assembly. The setting of the rotating mechanism 6 facilitates the rotational displacement of the overall angle of the yarn guide hook 3.

[0025] Since the yarn guide hook 3 is difficult to lock and easily rotates after the angle of the yarn guide hook 3 is adjusted in the prior art, the device is provided with an adjustment and fixing mechanism 4, which includes a rotating shaft 401 rotatably connected to the U-shaped frame 2, a fixing frame 402 is fixedly connected to the rotating shaft 401, a handle 403 is installed on the front of the fixing frame 402, and the yarn guide hook 3 is installed on the fixing frame 402, a gear 404 is installed at the end of the rotating shaft 401, and a fixing component 405 is provided on one side of the gear 404 to fix the fixed frame 402 after rotation.

[0026] The fixing assembly 405 includes a stretching rod 4051 that is slidably connected to the through hole opened on the U-shaped frame 2. A compression spring 4052 is provided between the stretching rod 4051 and the inner wall of the U-shaped frame 2. A pull ring 4053 is installed at the front end of the stretching rod 4051. A half gear 4054 is installed on the stretching rod 4051, and the half gear 4054 is meshed with the gear 404. When adjusting the yarn guide traction angle of the yarn guide hook 3 on the fixing frame 402, the pull ring 4053 is pulled, thereby driving the stretching rod 4051 to move forward from the inside of the through hole and squeeze the compression spring. 4052, thereby separating the half gear 4054 from the gear 404. At this time, hold the handle 403 and rotate the fixing frame 402 as needed, thereby driving the rotating shaft 401 and the gear 404 on the rotating shaft 401 to rotate. When the angle adjustment is completed, release the pull ring 4053, and the compression spring 4052 is reset under the action of its own elasticity, thereby driving the stretching rod 4051 to serve. At this time, the half gear 4054 is reset and re-engaged with the gear 404, thereby completing the angle fixation of the yarn guide hook 3, preventing the yarn guide hook 3 from rotating and affecting the yarn guide.

[0027] A limit plate 4055 is installed at the end of the stretching rod 4051, and the diameter of the limit plate 4055 is larger than the diameter of the stretching rod 4051. When the stretching rod 4051 is pulled, the limit plate 4055 is buckled on the U-shaped frame 2, thereby preventing excessive force from pulling the stretching rod 4051 out of the through hole.

[0028] Since the prior art uses multiple sets of nut threads to fit together to install the yarn guide hook 3, which is cumbersome to operate, the device is also provided with a mounting mechanism 5, which includes a mounting plate 501 mounted on the back of the yarn guide hook 3, and the mounting plate 501 is mounted inside the mounting groove opened on the fixing frame 402, and the interior of the mounting plate 501 is provided with sliding holes 502 on the upper and lower sides, and the inner wall of the sliding hole 502 is installed with an extension spring 503, and the outer end of the extension spring 503 is installed with a slider 504 that is slidably connected to the inside of the sliding hole 502, and a connecting handle 505 is installed between the two sliders 504, and the connecting handle 505 is slidably connected to the inside of the sliding groove opened on the right side of the mounting plate 501 and communicated with the sliding hole 502. A clamping block 506 is installed on the left side, and a clamping cavity 507 is provided on the inner walls of the left and right sides of the installation groove, which is engaged with the slider 504 and the clamping block 506. When the yarn guide hook 3 needs to be installed, the clamping block 506 on the left side of the installation plate 501 is inserted into the inside of the clamping cavity 507 on the left side of the installation groove. This pulls the connecting handle 505 to slide to the left along the slide groove, thereby driving the slider 504 to slide toward the inside of the slide hole 502 and squeezing the extension spring 503. When the installation plate 501 is completely engaged in the interior of the installation groove, the connecting handle 505 is released, and the extension spring 503 is reset under the action of its own elasticity, thereby pushing the slider 504 to reset and insert into the inside of the clamping cavity 507 on the right side of the installation groove, thereby quickly completing the installation of the yarn guide hook 3.

[0029] Example 2

[0030] On the basis of Example 1, Figure 1-Figure 4 As shown, since the use position of the yarn guide hook 3 in the prior art is fixed, and during the yarn guiding traction process, it may be necessary to adjust the angle of the yarn guide hook 3 to adapt to different yarn guiding traction conditions, the device is also provided with a rotating mechanism 6, which includes a base 601 installed below the mounting post 1, a transmission member 602 is installed inside the base 601, a turntable 603 is installed on the outer end of the transmission member 602, a rotating shaft 604 is installed inside the transmission member 602, and the rotating shaft 604 is rotatably connected to the rotating hole opened on the base 601, and its top is connected to the mounting post 1. When the angle of the yarn guide hook 3 needs to be adjusted, the turntable 603 is turned to drive the worm in the transmission member 602 in the base 601 to rotate, thereby driving the worm gear meshing with it to rotate, and then driving the rotating shaft 604 on the worm gear to rotate, thereby driving the mounting post 1 and the yarn guide hook 3 thereon to rotate, thereby completing the angle adjustment of the yarn guide hook 3.

[0031] An annular guide rail 605 is installed at the bottom of the mounting post 1, and guide rubber wheels 606 are installed in an annular shape and equidistantly on the top of the base 601. The guide rubber wheels 606 are rotatably connected to the inside of the annular guide rail 605. When the mounting post 1 rotates along the rotating shaft 604, the annular guide rail 605 at the bottom of the mounting post 1 is driven to rotate on the guide rubber wheels 606, thereby making the rotation of the mounting post 1 more stable.
