The utility model is based on the electrostatic elimination device originally arranged at the yarn guiding roller at the front end of the beam winding machine, and then an electrostatic elimination device is arranged between the beam frame part of the beam winding machine and behind the headstock. The electrostatic elimination device is provided with two identical electrostatic bars at the upper and lower positions of the warp thread. The electrostatic bars are connected to the electrostatic elimination box through wire connectors. The electrostatic bars are respectively fixed on two fixed rods, and the two fixed rods are installed on two support rods located on both sides of the beam winding machine. A number of discharge needles are evenly distributed on the electrostatic bars, and a protective cover with a grounding wire is also arranged outside the electrostatic bars. The utility model has the advantages of simple structure, convenient installation and operation, effectively eliminating the static electricity generated on the warp thread, and ensuring the product quality.

[0003] The beam winding machine adopts a conventional method for installing electrostatic bars. A fixed bracket is installed on the headstock crossbeam, and then the electrostatic bars are installed on the fixed bracket.

[0023] During use, the yarn cloth 3 is wound around the auxiliary roller 4 and the first roller 7 and then wound into the loom shaft 2. When the diameter of the loom shaft 2 increases during winding the yarn cloth 3, the second roller 8 is pushed to move. During this process, the telescopic rod 20 is telescoped and the square frame 19 is sleeved with the support rod 21 to realize real-time adjustment of the angle of the static eliminator 26 installed on the rotating rod 17. At the same time, the distance between the static eliminator 26 and the yarn cloth 3 is adjusted by the telescopic electric cylinder 22, so as to ensure that the yarn cloth is always within the effective working range distance of the static eliminator, ensuring the static elimination effect and avoiding affecting the quality of the loom shaft produced.

[0024] Embodiment 2: On the basis of Embodiment 1, the T-shaped slider 9 in the installation component is fixedly arranged on the side wall of the fixed plate 6, the sliding plates 10 are symmetrically and fixedly arranged on the inner walls of the two side machine tables 1, and T-shaped sliding grooves 11 are formed on the side walls of the sliding plates 10; the limiting plate 12 is fixedly arranged at the bottom end of the sliding plate 10, the pushing plate 13 is fixedly arranged at the bottom end of the fixed plate 6, a fixed column 14 is fixedly arranged at the side end of the pushing plate 13, the end of the fixed column 14 is movably inserted into the limiting plate 12, and a spring 15 is sleeved on the fixed column 14; both ends of the rotating rod 17 are rotatably arranged on the second bracket 16, the bottom end of the second bracket 16 is fixedly connected to the machine table 1, and two symmetrically perpendicular connecting rods 18 are fixedly arranged at the bottom end of the rotating rod 17, and a square frame 19 is fixedly arranged at the end of the connecting rod 18; the telescopic rods 20 are symmetrically and rotatably arranged on the rotating shafts of the auxiliary rollers 4, the output ends of the telescopic rods 20 are rotatably connected to the fixed plate 6, and the support rods 21 are fixedly arranged on the side walls of the output rods of the telescopic rods 20; the T-shaped slider 9 and the T-shaped sliding groove 11 are correspondingly arranged and have the same number of sets, and the T-shaped slider 9 is movably clamped in the T-shaped sliding groove 11; the spring 15 is in a compressed state, and both ends of the spring 15 are respectively clamped with the limiting plate 12 and the pushing plate 13, and the second roller 8 is clamped with the loom shaft 2; the support rod 21 is perpendicular to the yarn cloth 3 wound between the auxiliary roller 4 and the first roller 7, the support rod 21 and the square frame 19 are correspondingly arranged and have the same number of sets, the support rod 21 is sleeved with the square frame 19, and the inner wall of the square frame 19 is movably embedded with a ball in contact with the support rod 21.

[0025] During use, during the process of installing and winding the yarn cloth 3 into the loom shaft 2, the second roller 8 is always in clamping contact with the loom shaft 2 under the action of the spring 15. As the diameter of the loom shaft 2 winding the yarn cloth 3 continuously increases, the loom shaft 2 pushes the second roller 8 during this process, causing the T-shaped slider 9 on the fixed plate 6 to slide along the T-shaped sliding groove 11. At the same time, the distance between the auxiliary roller 4 and the first roller 7 increases and the telescopic rod 20 extends, and the square frame 19 moves along the support rod 21, thereby rotating the angle of the rotating rod 17, so as to realize real-time adjustment of the angle of the static eliminator 26 installed at the side end of the rotating rod 17 to be perpendicular to the yarn cloth 3 between the auxiliary roller 4 and the first roller 7, ensuring that the yarn cloth 3 is always within the effective working range angle of the static eliminator 26.

The photoelectric switches 24 detect the distance between the mounting plate 23 and the yarn cloth 3.

[0027] During use, the photoelectric switches 24 and the telescopic electric cylinders 22 are connected to the PLC. After the static electricity bar 26 is fixedly installed on the mounting plate 23 by screws, the distance between the mounting plate 23 and the yarn cloth 3 is set. Then, during the operation of the device, the photoelectric switches 24 can detect the distance between the yarn cloth 3 and the static electricity bar 26. When the distance exceeds the set ideal working distance, the photoelectric switches 24 feed back signals to the PLC, and the PLC gives signals to the telescopic electric cylinders 22 to control the telescoping of the telescopic electric cylinders 22, so as to ensure that the yarn cloth 3 is always within the effective working range distance of the static electricity bar 26.
