Description

Technical Field

[0001] The utility model belongs to the technical field of wire production, in particular to a preheating protection device for wire production. Background Art

[0002] During the process of wire preheating and subsequent coating of insulation layer, the wire is prone to oxidation after heating. During the heating process, the surface temperature of the wire rises. Especially when the wire is exposed to the air, oxygen reacts with the metal on the surface of the wire to form oxides, which not only reduces the conductivity of the wire, but also may cause the contact resistance to increase, thus affecting the performance and reliability of the entire electrical system.

[0003] At present, in order to prevent the oxidation of the scheduled wires, inert gas (such as nitrogen) is mostly introduced into the production environment or the wires are immersed in corrosion inhibitor. The introduction of nitrogen replaces the oxygen in the air, thereby reducing the risk of oxidation. However, this method is often limited in effect when the structure is complex or the gas distribution is uneven. Coating with corrosion inhibitor is an effective protective measure, but the traditional immersion method often leads to uneven coating. Due to the fluidity and viscosity of the corrosion inhibitor, some areas may not be fully covered during the wire immersion process, or the amount of corrosion inhibitor applied is too small. In addition, in industrial production, the demand for batch processing of multiple wires is increasing. The existing immersion coating method is usually difficult to achieve efficient batch coating, and multiple wires cannot be processed at the same time, resulting in low production efficiency. The limitations of this coating method are more obvious, affecting the overall production efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a preheating protection device for wire production to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] A preheating protection device for wire production is provided, comprising a base, a wire frame body is arranged above the base, a plurality of wire wheel bodies are rotatably connected above the wire frame body, a wire transmission channel is formed between two adjacent wire wheel bodies, a protection cover body is arranged on one side of the upper part of the base, a plurality of wire entry and exit holes are symmetrically arranged on both sides of the protection cover body, an anti-oxidation seat body is arranged inside the protection cover body, a plurality of accommodating groove bodies are arranged on the upper part of the anti-oxidation seat body, a spray cylinder body is rotatably connected inside the accommodating groove body, and a driving mechanism for driving the plurality of spray cylinder bodies to rotate is arranged above the anti-oxidation seat body.

[0006] As a further embodiment of the utility model: the spray cylinder is a hollow structure, and a plurality of liquid guide slots are arranged on the spray cylinder. The plurality of liquid guide slots are evenly distributed around the spray cylinder to ensure that the dripping range of the corrosion-inhibiting liquid of each liquid guide slot overlaps with each other, thereby covering the entire surface of the wire. The corrosion-inhibiting liquid can be affected by the combined effects of centrifugal force and gravity when flowing, and can drip more accurately onto the wire transported inside the spray cylinder, thereby avoiding liquid splashing or irregular flow.

[0007] As a further embodiment of the present invention: the liquid guide groove is a V-shaped liquid guide groove to enhance the fluidity of the liquid in the groove, guide the corrosion-inhibiting liquid to flow along the top of the liquid guide groove to the bottom of the liquid guide groove, form uniform small droplets and then drip down, ensuring that the corrosion-inhibiting liquid can drip evenly and stably from the liquid guide groove onto the surface of the wire.

By adjusting the rotation speed of the driven gear, the rotation speed of the spray cylinder can be accurately controlled, and then the coating rate and uniformity of the corrosion inhibitor liquid can be adjusted. During the rotation of the spray cylinder, due to the action of centrifugal force, the corrosion inhibitor liquid will evenly adhere to the inner wall of the spray cylinder and flow out from a number of liquid guide grooves provided on the upper part of the spray cylinder and drip onto the surface of the wire transported inside it. By rotating dripping, the surface of the wire is evenly coated to form a protective film to prevent the wire from being oxidized due to contact with high temperature and air.

The spray cylinder is used to apply the corrosion inhibitor. The spray cylinder rotates rapidly inside the containing tank. This rotation makes the corrosion inhibitor evenly adhere to the inner wall of the cylinder, thereby achieving more effective coating. Through the coordinated work of multiple spray cylinders, the system can process multiple wires at the same time, ensuring that each wire can obtain uniform and sufficient coating, avoiding the problem of uneven coating of corrosion inhibitor on the wire, and ensuring that the wire can effectively prevent oxidation after preheating.

[0011] As a further embodiment of the present utility model: a through hole is provided on one side of the upper part of the containing tank body, and the spray cylinder is rotatably connected to the outside of the through hole, and half of the spray cylinder is immersed in the corrosion-inhibiting liquid to ensure that sufficient liquid coating can be obtained during rotation, so that the liquid can be evenly adhered to the inner wall of the cylinder body and flow out from a plurality of liquid guide grooves provided on the upper part of the spray cylinder body and drip onto the surface of the wire transported inside it. The setting of the through hole allows the wire to pass conveniently during the coating process. No liquid guide groove is provided at one end of the spray cylinder body, and it is a ring structure rotatably connected to the containing tank body and is located on the outside of the through hole, providing a connection portion so that the spray cylinder can be stably rotated and connected to the inside of the containing tank body, thereby ensuring the stability of the spray cylinder body during rotation.

The constant supply helps to ensure that the spray cylinder obtains sufficient liquid coating during rotation, maintaining the consistency and uniformity of the coating. During the coating process, the liquid accumulation chamber can timely replenish the corrosion-inhibiting liquid required by the spray cylinder to avoid a decrease in coating effect due to liquid shortage.

[0013] As a further embodiment of the utility model: an inert gas inlet pipe is also provided on the upper part of the protective cover body, and the inert gas inlet pipe is used to introduce nitrogen to prevent the wire from being oxidized during the coating or heating process. This can ensure that the nitrogen introduction system is efficient, stable and safe, thereby effectively preventing the wire from being oxidized during the heating and coating process, and improving the reliability and efficiency of the overall process.

[0027] See also Figure 1-6 As shown, in the embodiment of the utility model, a preheating protection device for wire production includes a base 1, a wire frame 2 is arranged above the base 1, a plurality of wire wheel bodies 3 are rotatably connected above the wire frame 2, and two adjacent wire wheel bodies 3 form a wire transmission channel, a protective cover body 4 is arranged on one side of the upper part of the base 1, and a plurality of wire inlet and outlet holes 41 are symmetrically arranged on both sides of the protective cover body 4,

[0028] The protective cover body 4 serves to isolate the air and reduce the oxidation corrosion of the wire by external oxygen. An anti-oxidation seat body 5 is arranged inside the protective cover body 4. A plurality of receiving grooves 6 are arranged on the upper part of the anti-oxidation seat body 5. The interior of the receiving grooves 6 is rotatably connected with a spraying cylinder 7. A driving mechanism 8 for driving the plurality of spraying cylinders 7 to rotate is arranged above the anti-oxidation seat body 5.

[0029] After preheating, the wire passes through the wire frame 2 on one side above the base 1, and is transported toward the protective cover 4 through each conveying channel formed by two adjacent wire wheel bodies 3, and enters the protective cover 4 through a plurality of wire inlet and outlet holes 41 on one side of the protective cover 4 for anti-oxidation treatment. The driving mechanism 8 drives each spray cylinder 7 to rotate, so that the corrosion inhibitor can evenly drip on the wire transported in the spray cylinder 7 to ensure coating uniformity. After the corrosion inhibitor is coated, a plurality of wires are led out from the wire inlet and outlet holes 41 on the other side of the protective cover 4, and are transported to the next process through the wire conveying channel on the wire frame 2 on the other side. Multiple wire conveying channels and multiple spray cylinders 7 can process multiple wires at the same time, so that the wires can be quickly coated with the corrosion inhibitor after preheating, avoiding the problem of uneven coating of the corrosion inhibitor on the wires. Multiple wires can be processed at the same time, thereby improving the production efficiency of the wires and effectively preventing the oxidation of the preheated wires due to exposure to air at high temperature.

The plurality of liquid guiding slots 71 are evenly distributed around the spray cylinder 7 to ensure that the dripping range of the corrosion-inhibiting liquid of each liquid guiding slot 71 overlaps with each other, thereby covering the entire surface of the conductor. The corrosion-inhibiting liquid can be affected by the combined effects of centrifugal force and gravity when flowing, and can drip more accurately onto the conductor transported inside the spray cylinder 7, thereby avoiding liquid splashing or irregular flow.

[0031] For further examples, see Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the liquid guiding groove 71 is a V-shaped liquid guiding groove to enhance the fluidity of the liquid in the groove, guide the corrosion-inhibiting liquid to flow along the top of the liquid guiding groove 71 to the bottom of the liquid guiding groove 71, form uniform small droplets and then drip down, ensuring that the corrosion-inhibiting liquid can drip evenly and stably from the liquid guiding groove 71 onto the surface of the conductor.

[0032] For further examples, see Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, the inner wall of the liquid guide groove 71 is coated with a water-clear coating, which is a fluorosilicone resin coating. The surface of the fluorosilicone resin coating has extremely strong water resistance and low surface energy, which can effectively reduce the adhesion of the corrosion-inhibiting liquid on the inner wall of the liquid guide groove 71, in order to enhance the fluidity of the liquid and reduce liquid residue, so that the corrosion-inhibiting liquid can drip smoothly.

[0033] Furthermore, in one embodiment, see Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the spray cylinder 7 is provided with a driven gear 9, and the driven gear 9 is meshedly connected with a driving mechanism 8. By starting the driving mechanism 8, the driven gear 9 is driven to rotate, and then the spray cylinder 7 is rotated. By adjusting the rotation speed of the driven gear 9, the rotation speed of the spray cylinder 7 can be accurately controlled, and then the coating rate and uniformity of the corrosion inhibitor can be adjusted. During the rotation of the spray cylinder 7, due to the action of centrifugal force, the corrosion inhibitor will evenly adhere to the inner wall of the spray cylinder 7, flow out from a plurality of liquid guide grooves 71 provided on the upper part of the spray cylinder 7 and drip onto the surface of the wire transported therein. By rotating dripping, the surface of the wire is evenly coated to form a protective film to prevent the wire from being oxidized due to contact with air at high temperature, and can be effectively protected, reducing the risk of oxidation, thereby effectively extending the service life of the wire.

The output end of the driving motor 82 is fixedly connected with a first gear 83, and the first gear 83 is transmission-connected with a plurality of second gears 84. The first gear 83 and the plurality of second gears 84 are both fixedly connected with a rotating shaft 85, and the rotating shaft 85 is rotationally connected to the outside of the driving box body 81. The rotating shaft 85 is fixedly connected with a transmission gear 86, and the transmission gear 86 is meshingly connected with a driven gear 9. The rotation of the first gear 83 drives the plurality of second gears 84 to rotate, and the rotation of the first gear 83 and the plurality of second gears 84 drives the plurality of The rotating shaft 85 rotates, and the rotation of several rotating shafts 85 drives several transmission gears 86 to rotate. The rotation of the transmission gear 86 drives the driven gear 9 to rotate, and then drives several spray cylinders 7 to rotate inside the containing tank 6. The corrosion inhibitor is coated by rotating the spray cylinder 7, so that the corrosion inhibitor is evenly attached to the inner wall of the spray cylinder 7, and flows out from several liquid guide grooves 71 and drips onto the surface of the wire transported inside, thereby achieving more effective coating. Through the coordinated work of multiple spray cylinders 7, the system can process multiple wires at the same time, ensuring that each wire can obtain uniform and sufficient coating, avoiding the problem of uneven coating of the corrosion inhibitor on the wire, and ensuring that the wire can effectively prevent oxidation after preheating.

The receiving tank body 6 adopts a semi-open design, so that the corrosion-inhibiting liquid can be contained and maintained at a suitable liquid level at the bottom, while allowing a portion of the spray cylinder body 7 to be immersed in the liquid to form a good contact surface. Half of the spray cylinder body 7 is immersed in the corrosion-inhibiting liquid to ensure that sufficient liquid coating can be obtained during rotation, so that the liquid can be evenly attached to the inner wall of the cylinder body, and the liquid flows out from a plurality of liquid guide slots 71 provided on the upper portion of the spray cylinder body 7 and drips onto the surface of the wire transported therein.

This constant supply helps to ensure that the spray cylinder 7 obtains sufficient liquid coating when rotating, and maintains the consistency and uniformity of the coating. During the coating process, the liquid accumulation chamber 62 can timely replenish the corrosion-inhibiting liquid required by the spray cylinder 7 to avoid a decrease in the coating effect due to liquid shortage.
