[0002] Synthetic fiber is a commonly used synthetic fiber. Its molecular structure lacks polar groups and has poor moisture absorption. During production, processing or use, static electricity is easily generated and accumulated due to friction, peeling, etc. This static electricity can cause the fibers to stick together and entangle, attract dust and impurities, and may also affect the stability of subsequent processing steps, or even cause safety hazards in certain environments. Therefore, it is necessary to use appropriate technical means to eliminate static electricity in order to ensure smooth production and product quality.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a polyester fiber static eliminator, comprising a winding machine 1, with a support plate 2 fixedly connected to the front of the winding machine 1. The winding machine 1 is used for winding and arranging polyester fibers, maintaining uniform fiber tension during operation, preventing fiber entanglement and knotting, and providing stable working conditions for static elimination. Its body is made of anti-static material, which can reduce the impact of its own static electricity on the fibers. A static eliminator ion bar 3 is fixedly connected to the bottom of the support plate 2. The static eliminator ion bar 3 can generate a large number of ions with positive and negative charges, quickly neutralizing the static electricity on the surface of the polyester fibers. The ion release is uniform, and the static elimination efficiency is high. Its installation position is directly opposite the fiber winding path, ensuring that the ion wind can fully cover the fiber surface. An extension mechanism 4 is provided at the bottom of the static eliminator ion bar 3; the extension mechanism 4 can expand the diffusion range of the ion wind, adapt to polyester fiber widths of different widths, and improve the static elimination effect.

[0033] Reference Figure 2 , Figure 4 and Figure 5 The expansion mechanism 4 includes an expansion port 401 fixedly connected to the bottom of the antistatic ionizing air bar 3. The expansion port 401 is welded to the bottom of the antistatic ionizing air bar 3. The cross-section is an isosceles trapezoidal structure, which can guide the ionizing air to diffuse downward and expand the coverage area. Its inner wall is smooth to reduce airflow resistance and ensure smooth ionizing air delivery. A protective shell 402 is fixedly connected to the right side of the expansion port 401. The protective shell 402 is welded to the right side of the expansion port 401. It is made of sheet metal and can protect the internal connecting parts and prevent dust and fiber debris from accumulating and affecting operation. A support member is provided at the rear of the inner wall of the protective shell 402. A toothed plate 403 is provided on the outer wall of the support member. The support member provides a stable sliding guide for the toothed plate 403 to ensure that the toothed plate 403 moves only in the horizontal direction.

[0034] Furthermore, multiple sets of rotating columns 404 are rotatably connected to the inner walls of both the expansion port 401 and the protective shell 402. A rotating plate 408 is fixedly connected to the outer arc surface of the foremost rotating column 404, and a rear plate 410 is fixedly connected to the outer arc surface of the rearmost rotating column 404. Rotating plates 409 are fixedly connected to the outer arc surfaces of the remaining rotating columns 404. These multiple sets of rotating columns 404 are evenly distributed on the inner walls of the expansion port 401 and the protective shell 402, and are rotatably connected by precision bearings. The rotation is smooth and without jamming, and can synchronously drive the rotating plates 408, 409, and 410 to rotate. The surfaces of the rotating columns 404 are smooth, reducing frictional wear with the bearings. The outer arc surfaces of the multiple sets of rotating columns 404 are all fixedly connected to the outer arc surfaces of the bearings. A gear 405 is fixedly connected to the rotating column 404 and is keyed to the outer arc surface on the right side, ensuring reliable transmission. Multiple sets of gears 405 mesh with the toothed plate 403 to ensure that all rotating columns 404 move synchronously and avoid misalignment of the guide structure. A guide plate 407 is fixedly connected to the inner wall of the expansion port 401. Two sets of guide plates 407 are provided to disperse the positive and negative charged ions blown out by the antistatic ion fan bar 3 to the front and rear sides of the isosceles trapezoidal expansion port 401, thereby improving the antistatic efficiency on both sides. A limiting mechanism 5 is provided on the upper part of the protective shell 402. The limiting mechanism 5 can fix the toothed plate 403 after it is adjusted to the position, ensuring that the antistatic effect is continuous and reliable.

[0035] Reference Figures 2-4 The support includes a guide elliptical column 406 fixedly connected to the rear of the inner wall of the protective shell 402. The inner wall of the toothed plate 403 is slidably connected to the outer wall of the guide elliptical column 406. The guide elliptical column 406 is welded and fixed to the rear of the inner wall of the protective shell 402, parallel to the moving direction of the toothed plate 403. The surface is polished, resulting in high smoothness and reducing frictional resistance with the inner wall of the toothed plate 403, making the toothed plate 403 slide more smoothly. The outer teeth of the gear 405 mesh with the bottom outer teeth of the toothed plate 403. The meshing of the gear 405 and the toothed plate 403 can accurately convert the linear motion of the toothed plate 403 into the rotational motion of the rotating column 404. Lubricating grease is applied to the meshing point to reduce tooth surface wear and extend service life. The guide plate 407 is inclined outward. The outward inclination of the guide plate 407 can guide the ion wind to diffuse to both sides, further expanding the coverage area and adapting to the antistatic needs of wide polyester fibers.

[0036] Reference Figures 3-5The inner wall of the rear plate 410 is elastically connected to a contact block 412 via a connecting spring 411. In its natural state, the connecting spring 411 pushes the contact block 412 backward, causing it to contact the rear inner wall of the expansion port 401, ensuring a seal and preventing leakage of ion air through the gap. The spring surface is rust-proofed to withstand humid workshop environments. The outer wall of the contact block 412 is slidably connected to the inner wall of the rear plate 410. The rear part of the contact block 412 is designed with double bevels, which contact the rear inner wall of the expansion port 401. The contact block 412 is made of rubber, providing good elasticity and sealing. The double bevel design facilitates the rotation of the rear plate 410 for opening or rotation in the opposite direction for closing. The outer wall of the contact block 412 is in contact with the rear plate 410. The sliding fit of the inner wall is smooth and does not affect the flipping of the rear plate 410. The front part of the rotating plate 408 is set as an arc surface, which contacts the front inner wall of the expansion port 401. The arc surface of the front part of the rotating plate 408 fits against the front inner wall of the expansion port 401, which can reduce airflow resistance and enhance sealing performance. The arc surface is polished and smooth without burrs, and there is no friction noise when it contacts the inner wall of the expansion port 401. The rear part of the rotating plate 408, the front and rear parts of the rotating plate 409, and the front part of the rear plate 410 are all provided with arc grooves. Multiple sets of arc grooves contact each other, which can form a sealed connection between the rotating plate 408, the rotating plate 409, and the rear plate 410, reducing the entry of dust and its fiber debris into the bottom opening of the antistatic ion fan bar 3.

[0037] Reference Figure 3The limiting mechanism 5 includes a fixing block 501 fixedly connected to the upper part of the protective shell 402. The inner wall of the fixing block 501 is elastically connected to a limiting post 503 via a return spring 502. The fixing block 501 is welded and fixed to the upper part of the protective shell 402. It adopts a solid metal block structure with high strength, which can provide stable support for the return spring 502 and the limiting post 503, ensuring the reliable operation of the limiting mechanism 5. A T-shaped plate 504 is fixedly connected to the front end of the toothed plate 403. The T-shaped plate 504 is welded and fixed to the front end of the toothed plate 403, which can drive the toothed plate 403 to move synchronously. At the same time, the T-shaped structure can prevent the toothed plate 403 from falling off the inner wall of the protective shell 402, improving the structural stability. A circular groove is opened on the upper part of the T-shaped plate 504, and the bottom of the limiting post 503 is inserted into the inner wall of the circular groove. The return spring 502 is a tension spring with elastic restoring force. In a stable, natural state, pulling the limiting post 503 downwards allows its bottom to be stably inserted into the circular groove, thus fixing the toothed plate 403. The circular groove has two sets of T-shaped plates 504 whose outer walls penetrate and slide to the front inner wall of the protective shell 402. This penetration facilitates manual control of the T-shaped plates 504's movement. A toggle groove 505 is provided on the right side of the T-shaped plate 504, providing a point of force for manual adjustment of the toothed plate 403's position. The outer wall of the limiting post 503 penetrates and slides to the inner wall of the fixing block 501, and the bottom outer arc surface of the limiting post 503 penetrates and slides to the upper inner wall of the protective shell 402. This penetration does not affect the limiting operation and allows for easy manual upward movement to release the limiting post 503's limiting function.

[0038] Working principle: Before operation, pull the limiting post 503 of the limiting mechanism 5 upward to disengage it from the circular groove of the T-shaped plate 504, releasing the fixation on the toothed plate 403. The T-shaped plate 504 is then pushed forward through the actuating groove 505, causing the toothed plate 403 to slide horizontally forward along the guide elliptical column 406 inside the protective shell 402. The toothed plate 403 meshes with the gears 405 of multiple sets of rotating columns 404, causing the rotating columns 404 to rotate synchronously, thereby driving the rotating plate 408 and the rotating plate 403 to rotate. 9. After the rear plate 410 is flipped to the open angle and adjusted to the correct position, the limiting post 503 is released, and the reset spring 502 pulls it to insert into the corresponding circular groove to complete the fixation. When not in use, the multiple sets of rotating posts 404 are reset, the connecting spring 411 in the rear plate 410 pushes the rubber contact block 412 to fit against the inner wall of the expansion port 401, the arc surface of the rotating plate 408 fits against the front inner wall of the expansion port 401, and the arc grooves of each plate contact each other to form multiple seals, reducing ion air leakage and the entry of foreign matter.

[0039] During operation, the winding machine 1 conveys polyester fibers with uniform tension, and its anti-static body avoids generating static interference. The positive and negative ion wind generated by the anti-static ion wind bar 3 is conveyed downwards and guided to diffuse to the front and rear sides by the guide plate 407 on the inner wall of the expansion port 401. At the same time, the opened rotating plate 408, rotating plate 409 and rear plate 410 further expand the coverage of the ion wind, ensuring that the ion wind fully covers the fiber surface and quickly neutralizes static electricity. The polyester fibers after static electricity elimination are smoothly wound up by the winding machine 1. The whole process achieves precise and comprehensive elimination of static electricity in polyester fibers through width adaptive adjustment and efficient ion wind coverage, ensuring the quality of fiber processing.
