When the height difference between the yarn transmission height and the conductor structure is too large, it is easy to cause wear to the yarn and then break the yarn. Therefore, the traditional yarn guiding device is not convenient to always maintain the uniformity of the yarn transmission height and the conductor structure height. In response to the above problems, it is urgently needed to carry out innovative design based on the original yarn guiding device. Utility Model Content

[0023] 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.

[0024] See also Figures 1-6 , the utility model provides a technical solution:

[0025] In order to solve the problems existing in the prior art, this embodiment adopts the following technical solution, a CNC tufted carpet machine yarn guide device that can avoid thread breakage, including a support frame 1, a servo motor 2 is installed on the back of the support frame 1 through a bracket, and yarn rollers 3 are evenly spaced on the output shaft of the servo motor 2, the outer side of the output shaft of the servo motor 2 is connected to one end of the movable shaft 4 through a pulley mechanism, and the other end of the movable shaft 4 is meshed with the movable cylinder 8 through a bevel gear set 7; it also includes: a screw rod 9, a bolt passes through the bottom of the movable cylinder 8, the bottom of the screw rod 9 is fixedly connected to one of the support cylinders 10, and the support cylinder 10 and the yarn roller 3 are arranged in a one-to-one correspondence, the movable cylinder 8 and the support frame 1 are rotatably connected, and the fixed rod 13 and the support frame 1 are slidably connected, the fixed rod 13 is arranged on the side of the screw rod 9, and the bottoms of the two fixed rods 13 are respectively fixed with support cylinders 10.

[0026] Since the yarn is wound in a roll, when its thickness gradually decreases after transmission, the transmission position will change accordingly. When the height difference between the yarn transmission height and the conductor structure is too large, it is easy to cause wear to the yarn and then break the yarn. Therefore, the traditional yarn guide device is not convenient to always keep the yarn transmission height and the conductor structure height consistent. The middle position of the movable shaft 4 is fixedly installed with a fan blade 5, and the outer side of the fan blade 5 is provided with a protective cover 6, and the protective cover 6 is fixed to the support frame 1; the side of the protective cover 6 is fixedly connected to one end of the air hose 14, and the other end of the air hose 14 is fixedly connected to the support frame 1; The end is fixed on one of the limiting tubes 11, and the protective cover 6 is connected to one of the limiting tubes 11 through the air supply hose 14; the limiting tube 11 passes through the top of the support frame 1, and the cross-section of the limiting tube 11 is an "L"-shaped structure, and the limiting tube 11 and the support frame 1 are slidably connected; the limiting tubes 11 are arranged at equal intervals on the support frame 1, and adjacent limiting tubes 11 are connected to each other through connecting tubes 12, and the bottom of each limiting tube 11 is connected to a support tube 10; a fixed cavity 101 is opened inside the support tube 10, and a feed hole 102 is evenly reserved on the inner wall of the support tube 10.

[0027] The servo motor 2 drives the yarn roller 3 to rotate to realize the transmission of the yarn. The yarn passes through the inside of the support tube 10 and is transmitted to the subsequent textile mechanism. When driving, the servo motor 2 can drive the movable shaft 4 to rotate through the pulley mechanism, and then drives the movable tube 8 to rotate through the meshing transmission of the bevel gear set 7. When the movable tube 8 rotates, it can drive the support tube 10 to rise continuously through the threaded transmission with the screw rod 9. Since the thread groove on the screw rod 9 is relatively tight, when the servo motor 2 drives the yarn roller 3 to rotate at high speed, it can ensure that the support tube 10 rises slowly, thereby ensuring that the support tube 10 is at the same height as the yarn transmission on the yarn roller 3, thereby avoiding yarn wear.

[0028] When the movable shaft 4 rotates, it can drive the fan blades 5 to rotate synchronously. Therefore, the side of the fan blades 5 that generates suction is interconnected with the air supply hose 14, and can suck the dust and fluff on the surface of the yarn passing through the inside of the support tube 10 into the fixed cavity 101 through the feed hole 102, and then transmit it to the connecting tube 12 through the corresponding limiting tube 11, and finally enter the air supply hose 14 and then be discharged, so as to realize the cleaning of the yarn. When the screw rod 9 is raised and lowered, it can drive one of the limiting tubes 11 to slide on the support frame 1, and then the adjacent limiting tubes 11 are connected and raised and lowered synchronously through the connecting tube 12, which on the one hand ensures the stable lifting and lowering of the support tube 10, and on the other hand does not affect the transmission of gas.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
