Description

Technical Field

[0001] This utility model relates to the field of static electricity treatment technology in polyester production, specifically to a static electricity elimination device for polyester filament production. Background Technology

[0002] In the production of polyester filament, molten polyester material is extruded from the spinning box and stretched into filaments by the spinneret. Due to the friction between the fiber and the spinneret, static electricity is easily generated. Static electricity can cause the filaments to scatter and entangle, affecting product quality and production efficiency.

[0003] Traditional methods of static elimination, such as humidification and antistatic agent spraying, have problems such as unstable effects and fiber contamination. In existing technologies, ion fans can be used to neutralize static electricity, but a single fan is difficult to cover the entire filament and lacks a stable guiding structure.

[0004] Therefore, there is an urgent need for an electrostatic elimination device that combines water mist humidification, ion neutralization, and yarn guiding adjustment to improve the production quality of polyester filament. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electrostatic elimination device for polyester filament production, which solves the problem of static electricity generated by friction between the filament and the spinneret during polyester filament production. By combining ion wind with humidifying spray, the drape of the polyester filament and the effect of eliminating static electricity are effectively improved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a static electricity elimination device for polyester filament production, comprising a spinning box and a support. Spinnerets are symmetrically arranged on both sides of the lower end of the spinning box, and a placement groove is formed between two of the spinnerets. A water spray pipe is provided in the placement groove, and several spray nozzles are fixed on both sides of the side wall inside the placement groove. An atomizing humidifier is connected to the outer end of the water spray pipe. An ion fan is fixed at the lower end of the placement groove to blow water mist onto the polyester filament and neutralize static electricity.

[0007] Furthermore: conductive rod one is fixed at both ends of the spinneret, conductive rod one is connected to the bracket, conductive rod two is fixed at the lower end of the bracket, and conductive rod one and conductive rod two are integrally formed and grounded.

[0008] Furthermore: the bracket is provided with an adjustable wire guide mechanism, which includes a wire guide frame, a connecting rod and a fixing seat. The connecting rod is fixed to both ends of the outer side of the wire guide frame, and the other end of the connecting rod is connected to the fixing seat. A screw is threaded to the outer side of the fixing seat. The wire guide frame is matched with the polyester filament, and the fixing seat is slidably fixed on the conductive rod.

[0009] Furthermore, a second ion fan is also provided at the lower end of the bracket, and the second ion fan operates synchronously with the ion fan below the placement tank.

[0010] Furthermore, the interior of the ion fan is equipped with rust-proof electrodes.

[0011] Furthermore, the aperture of the guide frame is not less than the outer diameter of the polyester filament.

[0012] This invention provides an electrostatic elimination device for polyester filament production. Compared with the prior art, it has the following advantages:

[0013] This electrostatic eliminator for polyester filament production significantly reduces static electricity accumulation in polyester filaments through the combined effects of water mist humidification and ion fan. The adjustable filament guide mechanism ensures the filaments remain vertically downward, preventing filament drift and improving production stability. The conductive rod and filament guide mechanism work together to enhance static electricity discharge efficiency. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-5This utility model provides a technical solution: an electrostatic elimination device for polyester filament production; specifically, it consists of a spinning box 1 and a support 2. The spinning box 1 is fixedly installed at the upper end of the support 2. The polyester material enters from the upper end of the spinning box 1, melts through internal heating, and is drawn into filaments by its own gravity. The filaments then pass through a spinneret 3 fixed at the feed end of the spinning box 1. This is existing technology and will not be described in detail here. The spinnerets 3 are located on both sides of the lower end of the spinning box 1. A placement groove 4 is provided between the spinnerets 3. A water spray pipe 5 is fixed in the placement groove 4. Spray nozzles 6 are fixed on both sides of the water spray pipe 5 located in the placement groove 4. The water spray pipe 5 is connected to an atomizing humidifier to spray water mist through the spray nozzles 6. An ion fan 12 is fixed at the lower end of the placement groove 4. The ion fan 12 sprays the atomized group through it. The sprayed water mist and the neutralizing ions from the ion fan 12 eliminate static electricity in the polyester filament, thereby neutralizing and eliminating the static electricity generated by the friction between the polyester filament and the spinnerets 3.

[0022] Conductive rod 1 7 is fixedly connected to both ends of the spinneret 3. Conductive rod 1 7 is connected to the bracket 2. Conductive rod 2 8 is fixed at the lower end of the bracket 2. Conductive rod 1 7 and conductive rod 2 8 are integrally formed. The static electricity on the spinneret 3 is conducted away through conductive rod 1 7 and conductive rod 2 8. The lower end of conductive rod 2 8 is connected to the ground to conduct the static electricity to the ground for elimination.

[0023] A wire guiding mechanism is provided between the supports 2. The wire guiding mechanism includes a wire guide frame 11. The holes of the wire guide frame 11 are matched and corresponding to the holes of the spinneret 3. Connecting rods 10 are fixed on both sides of the wire guide frame 11. A fixing seat 9 is fixed on the outer end of the connecting rod 10. A screw 13 is threadedly connected to the outer side of the fixing seat 9. The fixing seat 9 is slidably set on the conductive rod 8. It can be fixed by tightening the screw 13 so that the screw 13 abuts against the outer wall of the conductive rod 8. Conversely, the fixing seat 9 can be slid to adjust. The setting can be adjusted up and down according to the thickness of the polyester filament. This can keep the polyester filament vertical and prevent the polyester filament from floating. The wire guide frame 11, connecting rods 10 and fixing seat 9 can all be set to conduct electricity. When the polyester filament comes into contact with the wire guide frame 11, static electricity can be conducted, which can further improve the static electricity elimination effect.

[0024] An ion fan 12 is also fixed at the lower end of the bracket 2. The ion fans 12 distributed vertically can keep the polyester filament vertically downward. The wind speed of the ion fan 12 is set synchronously. The inside of the ion fan 12 is gold-plated needle tip. The gold-plated needle tip can effectively prevent the inside of the ion fan 12 from rusting due to long-term moisture.
