Description

Technical Field

[0001] This utility model belongs to the field of electroplated brass wire production technology, specifically relating to a hot air nozzle. Background Technology

[0002] In the process of producing electroplated brass wire using tungsten or steel wire, multiple water washing processes are required. After the final water washing, before entering the drying oven for heat diffusion during the electroplating of brass and before the finished wire is wound up, it is necessary to ensure that the surface of the tungsten wire is dry. This is usually achieved by using high-pressure hot air from a nozzle to dry it. However, most nozzles simply pressurize the gas before it is ejected, resulting in poor pressurization and insufficient airflow to dry the surface of the tungsten wire, thus leading to poor drying of the tungsten or steel wire. Summary of the Invention

[0003] This invention addresses the problem that in the existing electroplated brass wire production process, the wire surface needs to be dried multiple times to ensure dryness, but existing pressurizing nozzles have poor pressurization effect and small air volume. It provides a hot air nozzle that uses a flow buffer and a pressurizing pipe to perform secondary pressurization of hot air, effectively ensuring the pressurization effect. In addition, the V-shaped groove ensures the diffusion of the blown air and effective contact with the wire surface. At the same time, the air outlet angle of the blow hole can be easily adjusted.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A hot air nozzle includes an air inlet assembly, a connector, and an air outlet assembly. The air inlet assembly includes an air inlet pipe and a diffuser pipe, with the air outlet end of the air inlet pipe fixedly connected to the diffuser pipe. The connector includes a sleeve and an annular plate, with the annular plate fixedly disposed on the inner side of one end of the sleeve. The sleeve is threaded onto the diffuser pipe, and the diffuser pipe corresponds vertically to the annular plate. The air outlet assembly includes a flow-retarding element, a pressure-boosting pipe, and a sealing plate. The flow-retarding element is disposed inside the diffuser pipe and is a hollow sphere with an air inlet at one end and an air outlet at the other end. The air inlet corresponds to the air inlet pipe. The air outlet end of the flow-retarding element extends out of the sleeve through a central opening in the annular plate. The air outlet is fixedly connected to the pressure-boosting pipe, and the air outlet end of the pressure-boosting pipe is fixedly disposed with a sealing plate. A blowing hole is formed in the center of the sealing plate. Airflow delivered by the air inlet pipe is pressurized by the flow-retarding element and the pressure-boosting pipe and then blown out from the blowing hole.

[0005] Preferably, the air outlet end of the sealing plate has a V-shaped groove, the V-shaped groove extends radially along the sealing plate and is connected to the air blowing hole, the diameter of the air blowing hole is smaller than the inner diameter of the pressurizing pipe, and the inner diameter of the pressurizing pipe is equal to the diameter of the air outlet. The V-shaped groove ensures that the air diffusion effectively dries the surface of the filament.

[0006] Preferably, the inner diameter of the diffuser is larger than the inner diameter of the air inlet pipe, the outer diameter of the flow-retarding element corresponds to the inner diameter of the diffuser, and the inner diameter of the annular plate is smaller than the outer diameter of the sphere of the flow-retarding element. The annular plate supports the flow-retarding element, preventing it from detaching from the sleeve under the impact of airflow.

[0007] Preferably, the diameter of the air outlet is smaller than the diameter of the air inlet to ensure the high-pressure blowing effect of the sweeping air.

[0008] Preferably, the diameter of the air inlet is larger than the inner diameter of the air inlet pipe and smaller than the inner diameter of the ball of the flow buffer to ensure the pressurization effect of the purging air.

[0009] Preferably, both ends of the V-shaped groove extend through the outer side of the sealing plate.

[0010] Preferably, a first limiting member is fixedly sleeved on the air inlet pipe, and a second limiting member is fixedly sleeved on the sleeve.

[0011] Preferably, both the first and second limiting members are prism structures with a through hole in the center, so that the equipment can be easily assembled or disassembled by clamping the limiting members with external tools.

[0012] Preferably, the air outlet assembly includes a vertical position and an inclined position, and the included angle α between the vertical position and the inclined position is 0-45°, and the air outlet angle of the air outlet assembly can be adjusted as needed.

[0013] Preferably, when the included angle α is 0-45°, the air inlet corresponds to the air outlet of the air inlet pipe and there is a gap between them.

[0014] The beneficial effects of this utility model through the above technical solution are as follows: 1. This utility model delivers gas into the slow-flow component located inside the diffuser through the air inlet pipe. The gas accumulates and is pressurized before being discharged from the pressurization pipe. Then, it is pressurized again in the pressurization pipe and discharged from the blower hole to blow air onto the surface of the filament to be dried. Based on the secondary pressurization, the air volume is effectively guaranteed.

[0015] 2. By adjusting the air outlet component to an inclined position, the high-pressure airflow blown out of the air outlet is inclined along the extension direction of the filament, which can dry a larger area of ​​the filament surface while ensuring the drying effect.

[0016] 3. The flow-slowing component of this utility model is a hollow sphere, and the connection between the air outlet component and the connecting component is approximately a spherical connection, so the air outlet direction of the blower hole can be easily adjusted.

[0017] 4. This utility model allows for easy disassembly and assembly of the air inlet assembly, connectors, and air outlet assembly of the equipment by using a sleeve and a threaded connection between the diffuser tube. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-5 As shown, this embodiment provides a hot air nozzle, wherein multiple hot air nozzles are provided and are all connected to an air supply pipe. The air supply pipe is connected to an air source, and multiple hot air nozzles are arranged along its axial direction on the lower side of the air supply pipe. All hot air nozzles are connected to the air supply pipe.

[0025] The hot air nozzle includes an air inlet assembly, a connector, and an air outlet assembly. The air inlet assembly includes an air inlet pipe 1 and a diffuser pipe 2. The air outlet end of the air inlet pipe 1 is fixedly connected to the diffuser pipe 2. The air inlet end of the air inlet pipe 1 is connected to the air supply pipe. Hot air in the air supply pipe is delivered to the air inlet pipe 1. The inner diameter of the diffuser pipe 2 is larger than the inner diameter of the air inlet pipe 1.

[0026] The connector includes a sleeve 3 and an annular plate 4. The annular plate 4 is fixedly installed on the inner side of one end of the sleeve 3. The sleeve 3 is threaded onto the diffuser tube 2. The diffuser tube 2 and the annular plate 4 are vertically aligned. The connection between the air inlet assembly and the air outlet assembly is achieved through the cooperation of the sleeve 3 and the annular plate 4.

[0027] The air outlet assembly includes a flow-retarding element 5, a pressure-boosting pipe 6, and a sealing plate 7. The flow-retarding element 5 is disposed inside the diffuser pipe 2. The flow-retarding element 5 is a hollow sphere with an air inlet 8 at one end and an air outlet 9 at the other end. The air inlet 8 corresponds vertically to the air inlet pipe 1. The air inlet pipe 1 delivers hot air to the diffuser pipe 2 and enters the flow-retarding element 5 through the air inlet 8. The outer diameter of the flow-retarding element 5 matches the inner diameter of the diffuser pipe 2. The diameter of the air inlet 8 is larger than the inner diameter of the air inlet pipe 1 but smaller than the inner diameter of the sphere of the flow-retarding element 5. After the airflow enters the flow-retarding element 5, the flow velocity decreases, the pressure increases, and... The airflow gathers and gradually increases in pressure within the flow-retardant 5. The diameter of the air outlet 9 is smaller than that of the air inlet 8, and the diameter of the air inlet 8 is smaller than the inner diameter of the diffuser 2. The air outlet 9 is fixedly connected to a pressurizing pipe 6, and the inner diameter of the pressurizing pipe 6 is equal to the diameter of the air outlet 9. After the hot air in the flow-retardant 5 is pressurized, it enters the pressurizing pipe 6. A sealing plate 7 is fixedly installed at the air outlet end of the pressurizing pipe 6. A blowing hole 10 is opened in the middle of the sealing plate 7. The diameter of the blowing hole 10 is smaller than that of the inner diameter of the pressurizing pipe 6. After the hot air is pressurized again in the pressurizing pipe 6, it is blown out through the blowing hole 10 to dry the surface of the filament 14.

[0028] The air outlet end of the sealing plate 7 has a V-shaped groove 11. The V-shaped groove 11 extends radially along the sealing plate 7 and is connected to the air blowing hole 10. Furthermore, both ends of the V-shaped groove 11 penetrate the outer side of the sealing plate 7, that is, the length of the V-shaped groove 11 is equal to the outer diameter of the sealing plate 7. By setting the V-shaped groove 11, the diffusion of hot air after being blown out of the air blowing hole 10 is limited, so that it is concentrated in the position close to the circumference of the filament 14, ensuring effective drying of the surface of the filament 14.

[0029] The air outlet end of the flow-slowing component 5 extends through the central opening of the annular plate 4 and out of the sleeve 3. The inner diameter of the annular plate 4 is smaller than the outer diameter of the sphere of the flow-slowing component 5. Thus, the flow-slowing component 5 is supported by the annular plate 4 and placed in the diffuser tube 2 above the annular plate 4, thereby achieving the connection and installation of the air outlet assembly.

[0030] A first limiting member 12 is fixedly sleeved on the air inlet pipe 1, and a second limiting member 13 is fixedly sleeved on the sleeve 3. Both the first limiting member 12 and the second limiting member 13 are prism structures with a circular hole through the center. Furthermore, the air inlet pipe 1, the first limiting member 12, and the diffuser pipe 2 are integrally formed, as are the sleeve 3 and the second limiting member 13, to ensure structural tightness and strength. Specifically, the outer side of the air inlet pipe 1 near the diffuser pipe 2 is set as a polygonal prism structure to form the first limiting member 12, and the outer side of the sleeve 3 is also set as a polygonal prism structure to form the second limiting member 13. When assembling or disassembling the air inlet assembly and the connecting parts, external tools such as wrenches can be used to limit and fix the first limiting member 12 or the second limiting member 13, and then they can be rotated relative to each other to achieve assembly and disassembly.

[0031] The air outlet assembly includes a vertical position and an inclined position. The included angle α between the vertical position and the inclined position is 0-45°. When the included angle α is 0-45°, the air inlet 8 corresponds to the air outlet end of the air inlet pipe 1 and there is a gap. Correspondingly, by rotating the sleeve 3 to move the annular plate 4 closer to or away from the lower end of the diffuser pipe 2, the distance between the air inlet 8 and the air inlet pipe 1 can be adjusted, thereby ensuring that there is enough space to adjust the inclination angle of the air outlet assembly and avoiding the side wall of the air inlet 8 touching the end face of the air inlet pipe 1, which would affect the angle adjustment of the air outlet assembly.

[0032] The assembly process of the hot air nozzle of this utility model is as follows: the air inlet pipe 1 and the diffuser pipe 2 are fixedly connected to the lower side of the air supply pipe. The air outlet assembly is installed into the sleeve 3 from top to bottom. The lower parts of the sealing plate 7, the pressurizing pipe 6 and the flow-retarding component 5 all pass through the middle of the annular plate 4 and extend out of the sleeve 3. Since the outer diameter of the flow-retarding component 5 is larger than the inner diameter of the annular plate 4, the upper part of the flow-retarding component 5 remains in the sleeve 3 and abuts against the inner wall of the annular plate 4 to ensure a seal. Then, the sleeve 3 is threaded onto the diffuser pipe 2. During this process, the upper part of the flow-retarding component 5 gradually enters the diffuser pipe 2. As the lower end of the diffuser pipe 2 and the upper side of the annular plate 4 gradually approach each other, the distance between the air inlet 8 and the air outlet of the air inlet pipe 1 gradually decreases until the lower end of the diffuser pipe 2 touches the annular plate 4, completing the assembly. At this time, a wire 14 (the wire is a washed steel wire, tungsten wire or electroplated brass wire to be wound) corresponds to the bottom of the hot air nozzle, so that the hot air nozzle dries the surface of the corresponding wire 14.

[0033] The hot air pressurization process is as follows: the air supply pipe continuously delivers hot air into the flow buffer 5 through the air inlet pipe 1. Since the diameter of the air outlet 9 of the flow buffer 5 is smaller than the diameter of the air inlet 8, the hot air accumulates and pressurizes in the flow buffer 5. At the same time, it enters the pressurization pipe 6 through the air outlet 9. Since the diameter of the blow hole 10 is smaller than the inner diameter of the pressurization pipe 6, the hot air accumulates and pressurizes in the pressurization pipe 6. Then it is blown out from the blow hole 10 onto the filament 14. Due to the setting of the V-groove 11, the length extension direction of the V-groove 11 is parallel to the axial direction of the filament. The high-pressure hot air blown out diffuses circumferentially along the surface of the filament 14 and axially dries the filament through the V-groove 11, ensuring air volume while ensuring high-pressure drying effect.

[0034] In actual use, adjust the air outlet assembly to the tilt position, so that one end of the V-groove 11 is close to the wire 14 and the other end is away from the wire 14 (e.g., Figure 5 As shown), this allows the high-pressure hot air to blow onto a larger surface area of ​​the corresponding filament 14. At the same time, the pressure boosting pipe 6 in the inclined position is not coaxial with the air inlet pipe 1 (that is, the axes of the pressure boosting pipe 6 and the air inlet pipe 1 intersect after extension). The hot air delivered by the air inlet pipe 1 enters the flow buffer 5 and impacts the side wall of the flow buffer 5 to decelerate, so as to better gather and pressurize in the flow buffer 5 and improve the pressurization effect.

Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
