Description

Technical Field

[0001] This invention relates to the field of copper processing technology, specifically to a waste copper particle extrusion anti-oxidation equipment and method. Background Technology

[0002] In the industrial process of scrap copper recycling and reuse, after scrap copper particles are extruded into copper wires, their surfaces readily react with oxygen in the air, leading to oxidation and affecting the quality and subsequent processing performance of the copper wires. Traditional anti-oxidation methods often involve coating with antioxidants or packaging protection, but these methods suffer from problems such as complex operation, high cost, and short-lasting anti-oxidation effects. Especially on large-scale continuous production lines, how to efficiently and stably prevent oxidation of copper wires has become a key factor restricting the development of the scrap copper recycling industry.

[0003] Existing anti-oxidation methods are divided into two types: coating and immersion. Immersion methods may have the following problems: large amounts of chemicals are used, and liquid films of different thicknesses are generated during anti-oxidation. Especially when exiting the water, due to gravity, the liquid will gather downwards, and the surface tension cannot make the liquid film uniform in a short time, resulting in an uneven distribution of coating with a thin top and a thick bottom. Furthermore, when the copper wire passes through the liquid quickly, air bubbles may be generated on the surface and adhere to the copper wire, which seriously affects the quality of anti-oxidation. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that bubbles may be generated on the surface of copper wire when it passes through liquid rapidly, and liquid films of different thicknesses may be generated on the surface of copper wire. The present invention provides a waste copper particle extrusion anti-oxidation device and method.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: An anti-oxidation device for extruding waste copper particles, the anti-oxidation device is used to prevent oxidation of copper wire produced after extruding waste copper particles, the anti-oxidation device includes an immersion mechanism, a pre-wetting mechanism, a post-treatment mechanism and an anti-oxidation liquid; The immersion mechanism includes an immersion tank; The pre-impregnation mechanism includes a first roller and a second roller; The immersion tank is equipped with a post-treatment mechanism. The anti-oxidation solution is placed in the immersion tank. The copper wire abuts against the first roller and the second roller respectively. The abutment position of the copper wire and the first roller is higher than the abutment position of the copper wire and the second roller. The lower ends of the first roller and the second roller are immersed in the anti-oxidation solution. The first roller and the second roller are placed in sequence at the copper wire inlet end. The post-treatment mechanism is placed at the copper wire outlet end. The first roller and the second roller are used to reduce the amount of air bubbles generated after the copper wire enters the anti-oxidation solution. The post-treatment mechanism makes the thickness of the liquid film on the surface of the copper wire more uniform.

[0006] During the copper wire conveying process, it gradually enters the anti-oxidation solution in the immersion tank. Since the copper wire comes into contact with the first and second rollers respectively, the conveying of the copper wire drives the first and second rollers to rotate. Before entering the anti-oxidation solution, the bottom of the first and second rollers is submerged below the surface of the solution. Therefore, during the rotation of the first and second rollers, the bottom continuously passes through the anti-oxidation solution, thus keeping the surface of the copper wire adhered to it. As the copper wire passes through the first and second rollers, a small amount of anti-oxidation solution can be pre-wetted onto the surface of the copper wire. Furthermore, the contact between the first and second rollers and the copper wire effectively drives away and replaces air on the surface of the copper wire, forming an initial liquid film and guiding the copper wire smoothly into the anti-oxidation solution. This effectively reduces the amount of air bubbles generated after the copper wire enters the solution, preventing air bubbles from affecting the anti-oxidation treatment effect. When the copper wire exits the solution, it initially carries out a large amount of anti-oxidation solution. The post-treatment mechanism then blocks this large amount of solution, making the liquid film thickness on the surface of the copper wire more uniform after exiting the solution, further improving the quality of the anti-oxidation treatment.

[0007] Furthermore, two sets of connecting parts are symmetrically arranged inside the immersion mechanism, and the two sets of connecting parts are rotatably connected to the shaft ends of the first drum and the second drum, respectively. The outer ring surface of the first roller is provided with a first immersion groove; The outer ring surface of the second roller is provided with a second wetting groove; The cross-sectional shapes of the first and second impregnation tanks are matched with the copper wire. The copper wire abuts against the first and second impregnation tanks respectively, and the abutment position of the copper wire and the first impregnation tank is higher than the abutment position of the copper wire and the second impregnation tank.

[0008] The connector design allows the first and second rollers to be stably installed within the immersion mechanism and to rotate flexibly. The cross-sections of the first and second immersion tanks are arc-shaped, which better matches the shape of the copper wire, increases the contact area, and improves the pre-immersion effect. The contact point between the copper wire and the first immersion tank is higher than that between the copper wire and the second immersion tank. This arrangement allows the copper wire to undergo a gradual immersion process as it passes through the two rollers, further optimizing the pre-immersion effect and ensuring that the surface of the copper wire is uniformly covered with a thin layer of anti-oxidation solution before entering the anti-oxidation solution, laying a good foundation for subsequent anti-oxidation treatment.

[0009] Furthermore, anti-oxidation equipment also includes a recycling mechanism; The post-processing mechanism includes a scraper; One end of the scraper abuts against the copper wire, and the end of the scraper that abuts against the copper wire is made of silicone. The other end of the scraper is fixed to the recycling mechanism.

[0010] When the silicone scraper comes into contact with the copper wire, it effectively scrapes off excess anti-oxidation liquid from the surface of the copper wire without damaging it, thus ensuring the quality of the copper wire. The recycling mechanism provides stable support for the scraper, allowing it to be accurately positioned at the point where the liquid exits from the copper wire, continuously scraping off the anti-oxidation liquid. Furthermore, the recycling mechanism can collect and recycle the scraped-off anti-oxidation liquid, avoiding waste and environmental pollution, and improving resource utilization.

[0011] Furthermore, the post-processing mechanism also includes an air knife and a connecting frame; The air knife includes an air inlet, a base plate, and a base plate. An air inlet is provided on one side of the base plate, and a base plate is provided below the base plate. An air outlet groove is provided between the base plate and the base plate. The immersion tank is equipped with a connecting frame, on which a base plate is placed. The long end of the base plate is parallel to the copper wire, and the outlet of the air outlet duct faces the lower end of the copper wire.

[0012] The air inlet is used to connect to an external air source, providing a stable airflow for the air knife. The air outlet slot design between the substrate and the base plate allows the airflow to be concentrated and evenly blown onto the copper wire surface. The connecting frame stably fixes the air knife in the immersion tank, ensuring the accurate positioning of the air knife and enabling continuous sweeping of the copper wire surface after liquid discharge. When the copper wire passes under the air knife, the parallel and stable laminar airflow blown by the air knife through the air outlet slot causes the airflow to adhere to the liquid film on the copper wire surface, forming a continuous and uniform high-speed shear force field. Under the action of this force field, the thicker areas of the liquid film bear greater shear stress due to the higher relative velocity, and more liquid is removed, thereby achieving automatic thickness compensation. At the same time, the liquid spreads laterally under the action of surface tension. The two work together to ultimately process the liquid film into a coating of uniform thickness. Moreover, the high-speed adhering airflow creates a low-pressure field on the outside of the liquid film. The pressure difference formed with the ambient air pressure adsorbs the liquid film onto the copper wire surface, further improving the anti-oxidation treatment effect of the copper wire and ensuring the quality stability of the copper wire.

[0013] Furthermore, through holes are provided on both ends of the immersion tank, through which copper wires pass.

[0014] The through-hole design allows the copper wire to smoothly enter and exit the immersion tank, while also guiding the wire to ensure it passes accurately through each processing unit during transport, thus guaranteeing the smooth progress of the entire anti-oxidation treatment process.

[0015] Furthermore, the anti-oxidation equipment also includes a conveying mechanism; The conveying mechanism includes several sets of conveying rollers. A set of conveying rollers is provided at the liquid inlet end and the liquid outlet end of the copper wire, and several sets of conveying rollers are provided inside the anti-oxidation liquid. The conveyor roller and the immersion cylinder are rotatably connected, and the conveyor roller and the copper wire abut against each other.

[0016] The conveyor rollers enable the automatic transport of copper wire throughout the anti-oxidation equipment. The first set of conveyor rollers accurately feeds the copper wire into the anti-oxidation solution in the immersion tank to begin the anti-oxidation treatment process. The conveyor rollers placed in the anti-oxidation solution can assist in the smooth transport of the copper wire in the solution, ensuring that the copper wire is in full contact with the anti-oxidation solution and improving the effect of the anti-oxidation treatment. The second set of conveyor rollers then pulls the copper wire that has completed the anti-oxidation treatment out of the immersion tank and sends it to the subsequent processing stage.

[0017] Furthermore, the recycling mechanism includes a recycling tank, a filter screen, and a recycling pipe. The immersion tank is located inside the recycling tank, and a scraper and a filter screen are arranged sequentially along the conveying direction of the copper wire inside the recycling tank. A recycling pipe is located on the outer side of the recycling tank, and the recycling pipe is connected to the immersion tank pipeline.

[0018] The recovery tank is used to collect the anti-oxidation liquid scraped off by the scraper and the anti-oxidation liquid dripping from the surface of the copper wire. The filter screen can filter the recovered anti-oxidation liquid to remove any impurities and solid particles that may be present, ensuring the purity of the recovered anti-oxidation liquid so that it can be recycled again. The recovery pipe transports the filtered anti-oxidation liquid back into the immersion tank, realizing the recycling of the anti-oxidation liquid, reducing production costs, and also reducing the discharge of waste liquid.

[0019] Furthermore, the anti-oxidation equipment also includes a winding mechanism; The winding mechanism includes a winding frame, a winding drum, and a motor. The motor is mounted on the winding frame, and the winding drum is mounted on the output end of the motor. The winding drum and the winding frame are rotatably connected. The winding frame is placed on the outlet side of the immersion tank, with the winding drum and copper wire in contact.

[0020] The winding rack provides a stable support platform for the winding drum and motor, ensuring the normal operation of the winding mechanism. The motor output torque drives the winding drum to rotate, evenly winding the copper wire, which has undergone anti-oxidation treatment and post-processing, onto the winding drum. The contact method between the winding drum and the copper wire allows the copper wire to be tightly wound onto the winding drum, avoiding loosening or tangling of the copper wire during the winding process. This ensures the quality and neatness of the wound copper wire, facilitating subsequent storage and transportation.

[0021] Furthermore, the method includes the following steps: S1. The copper wire is pulled through the anti-oxidation solution by a motor; S2. The copper wire is pre-impregnated by the first and second rollers; S3. Use a scraper to scrape off the anti-oxidation solution that has just come out of the copper wire; S4. Use an air knife to make the thickness of the liquid film on the surface of the copper wire uniform; S5. The copper wire is wound up using a winding drum.

[0022] After the motor starts, it drives the winding drum to rotate, which in turn pulls on the copper wire. The copper wire is then guided through various processing stages by the conveying mechanism, finally entering the anti-oxidation solution in the immersion tank to begin the anti-oxidation treatment. Before entering the solution, the copper wire contacts the first and second rollers. Since the surfaces of the first and second rollers are coated with anti-oxidation solution, a small amount of solution pre-wets the copper wire as it passes through, simultaneously driving away and displacing air from the surface to form an initial liquid film. This reduces the amount of air bubbles generated after the copper wire enters the solution. When the copper wire exits the solution, a large amount of air bubbles are carried away from its surface. A certain amount of anti-oxidation liquid is applied, and at this point, the scraper comes into contact with the copper wire to scrape off the excess anti-oxidation liquid, preventing waste and dripping that could pollute the equipment and the surrounding environment. Due to the gravity of the liquid film on the surface of the copper wire, the liquid film on the surface of the copper wire after scraping may still be in a state of being thinner at the top and thicker at the bottom. The airflow blown out by the air knife acts on the surface of the copper wire, which can automatically compensate for the thickness of the liquid film and form a uniform coating. At the same time, the low-pressure field generated by the airflow adsorbs the liquid film onto the surface of the copper wire, further improving the anti-oxidation treatment effect. Finally, the copper wire that has completed the anti-oxidation treatment and post-treatment is evenly wound up by the winding drum under the drive of the motor, which facilitates subsequent storage and transportation.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention, by setting a pre-wetting mechanism, uses the first roller and the second roller to pre-wet the copper wire, which effectively reduces the amount of bubbles generated after the copper wire enters the anti-oxidation liquid, thereby avoiding the problem of bubbles adhering to the surface of the copper wire and affecting the anti-oxidation effect; 2. The present invention uses a scraper and an air knife in the post-processing mechanism to scrape off excess anti-oxidation liquid from the freshly drained copper wire and to make the liquid film thickness on the surface of the copper wire uniform, thereby further improving the anti-oxidation effect and ensuring the quality of the copper wire and its subsequent processing performance. 3. This invention recycles and filters the scraped-off anti-oxidation liquid through a recycling mechanism, thereby achieving the recycling of the anti-oxidation liquid and reducing production costs.

[0026] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example: Figures 1-7 As shown, the present invention provides a technical solution: a waste copper particle extrusion anti-oxidation device and method.

[0028] like Figure 1 As shown, a waste copper particle extrusion anti-oxidation device is used to perform anti-oxidation treatment on copper wire 6 produced after extrusion of waste copper particles. The anti-oxidation device includes an immersion mechanism 1, a pre-wetting mechanism 2, a post-treatment mechanism 3, and an anti-oxidation liquid 7. Immersion mechanism 1 includes immersion tank 11; The pre-impregnation mechanism 2 includes a first roller 21 and a second roller 22; The immersion tank 11 is equipped with a post-treatment mechanism 3. The anti-oxidation solution 7 is placed in the immersion tank 11. The copper wire 6 is in contact with the first roller 21 and the second roller 22 respectively. The contact position between the copper wire 6 and the first roller 21 is higher than the contact position between the copper wire 6 and the second roller 22. The lower ends of the first roller 21 and the second roller 22 are respectively immersed in the anti-oxidation solution 7. The first roller 21 and the second roller 22 are placed in sequence at the liquid inlet end of the copper wire 6. The post-treatment mechanism 3 is placed at the liquid outlet end of the copper wire 6. The first roller 21 and the second roller 22 are used to reduce the amount of bubbles generated after the copper wire 6 enters the anti-oxidation solution 7.

[0029] During the copper wire 6 conveying process, it gradually enters the anti-oxidation solution 7 in the immersion tank 11. Since the copper wire 6 abuts against the first roller 21 and the second roller 22 respectively, the conveying of the copper wire 6 drives the first roller 21 and the second roller 22 to rotate. Before the copper wire 6 enters the anti-oxidation solution 7, because the bottom of the first roller 21 and the second roller 22 is submerged below the surface of the anti-oxidation solution 7, the bottom of the first roller 21 and the second roller 22 continuously passes through the anti-oxidation solution 7 during rotation, thus its surface is constantly adhered to the anti-oxidation solution 7. When the copper wire 6 passes through the first roller 21 and the second roller 22, a small amount of anti-oxidation solution 7 can be pre-attached to the copper wire. The surface of the wire 6 is pre-wetted, and the contact between the first roller 21 and the second roller 22 and the copper wire 6 can more effectively drive away and replace the air on the surface of the copper wire 6, forming an initial liquid film and guiding the copper wire 6 smoothly into the anti-oxidation liquid 7. This effectively reduces the amount of bubbles generated after the copper wire 6 enters the anti-oxidation liquid 7, and avoids affecting the anti-oxidation treatment effect due to bubbles adhering to the surface of the copper wire 6. When the copper wire 6 exits the liquid, it is easy to carry out a large amount of anti-oxidation liquid 7 at the beginning. The post-treatment mechanism 3 blocks a large amount of anti-oxidation liquid 7 and makes the thickness of the liquid film on the surface of the copper wire 6 after exiting the liquid more uniform, further improving the quality of the anti-oxidation treatment.

[0030] like Figures 2-3 As shown, two sets of connecting parts 23 are symmetrically arranged inside the immersion tank 11, and the two sets of connecting parts 23 are rotatably connected to the shaft ends of the first roller 21 and the second roller 22, respectively. The outer surface of the first roller 21 is provided with a first immersion groove 211; The outer surface of the second roller 22 is provided with a second immersion groove 221; The cross-sectional shape of the first impregnation tank 211 and the second impregnation tank 221 is matched with that of the copper wire 6. The copper wire 6 abuts against the first impregnation tank 211 and the second impregnation tank 221 respectively. The abutting position of the copper wire 6 and the first impregnation tank 211 is higher than the abutting position of the copper wire 6 and the second impregnation tank 221.

[0031] The connector 23 allows the first roller 21 and the second roller 22 to be stably installed in the immersion mechanism 1 and to rotate flexibly. The cross-sections of the first immersion tank 211 and the second immersion tank 221 are arc-shaped, which can better match the shape of the copper wire 6, increase the contact area, and make the pre-immersion effect better. The contact position of the copper wire 6 with the first immersion tank 211 is higher than the contact position with the second immersion tank 221. This layout allows the copper wire 6 to have a gradual immersion process when passing through the two rollers, further optimizing the pre-immersion effect and ensuring that the surface of the copper wire 6 is uniformly covered with a thin layer of anti-oxidation liquid 7 before entering the anti-oxidation liquid 7, laying a good foundation for subsequent anti-oxidation treatment.

[0032] like Figure 4 As shown, the anti-oxidation equipment also includes a recycling mechanism 5; The post-processing mechanism 3 includes a scraper 31; One end of the scraper 31 abuts against the copper wire 6. The end of the scraper 31 that abuts against the copper wire 6 is made of silicone. The other end of the scraper 31 is fixed to the recycling mechanism 5.

[0033] When the silicone scraper 31 comes into contact with the copper wire 6, it effectively scrapes off excess anti-oxidation liquid 7 from the surface of the copper wire 6 without damaging the surface, thus ensuring the quality of the copper wire 6. The recycling mechanism 5 provides stable support for the scraper 31, allowing it to be accurately positioned at the liquid outlet of the copper wire 6, continuously scraping off the anti-oxidation liquid 7. Furthermore, the recycling mechanism 5 can collect and recycle the scraped anti-oxidation liquid 7, avoiding waste and environmental pollution, and improving resource utilization.

[0034] like Figures 4-5 As shown, the post-processing mechanism 3 also includes an air knife 32 and a connecting frame 33; The air knife 32 includes an air inlet 321, a base plate 322 and a base plate 323. The base plate 322 has an air inlet 321 on one side, and the base plate 323 is located below the base plate 322. An air outlet groove is located between the base plate 322 and the base plate 323. The immersion tank 11 is provided with a connecting frame 33, and a base plate 322 is provided on the connecting frame 33. The long end of the base plate 322 is parallel to the copper wire 6, and the outlet of the air outlet duct faces the lower end of the copper wire 6.

[0035] The air inlet 321 is used to connect to an external air source to provide a stable airflow for the air knife 32. The air outlet slot design between the substrate 322 and the base plate 323 allows the airflow to be concentrated and evenly blown onto the surface of the copper wire 6. The connecting bracket 33 stably fixes the air knife 32 in the immersion tank 11, ensuring the accurate positioning of the air knife 32 and enabling continuous sweeping of the surface of the copper wire 6 after liquid discharge. When the copper wire 6 passes under the air knife 32, the parallel and stable laminar airflow blown out by the air knife 32 through the air outlet slot causes the airflow to adhere to the liquid film on the surface of the copper wire 6, forming a holding... A continuous and uniform high-speed shear force field is applied. Under the action of this force field, the thicker areas of the liquid film bear greater shear stress due to the higher relative velocity, resulting in the removal of more liquid and thus achieving automatic thickness compensation. At the same time, the liquid spreads laterally under the action of surface tension. The two work together to process the liquid film into a coating with uniform thickness. Moreover, the high-speed adsorption airflow creates a low-pressure field on the outside of the liquid film. The pressure difference between the liquid film and the ambient air pressure adsorbs the liquid film onto the surface of the copper wire 6, further improving the anti-oxidation treatment effect of the copper wire 6 and ensuring the quality stability of the copper wire 6.

[0036] like Figure 2 As shown, the two ends of the immersion tank 11 are respectively provided with through holes 111, and the copper wire 6 passes through the through holes 111.

[0037] The through hole 111 allows the copper wire 6 to smoothly enter and exit the immersion tank 11, while also guiding the copper wire 6 to ensure that it passes accurately through each processing mechanism during the transport process, thus ensuring the smooth progress of the entire anti-oxidation treatment process.

[0038] like Figure 1 As shown, the anti-oxidation equipment also includes a conveying mechanism 4; The conveying mechanism 4 includes several sets of conveying rollers 41. The inlet and outlet ends of the copper wire 6 are each provided with a set of conveying rollers 41, and the anti-oxidation liquid 7 is provided with several sets of conveying rollers 41. The conveyor roller 41 and the immersion cylinder 11 are rotatably connected, and the conveyor roller 41 and the copper wire 6 abut against each other.

[0039] The conveyor rollers 41 enable the automatic conveying of copper wire 6 throughout the anti-oxidation equipment. The first set of conveyor rollers 41 accurately feeds the copper wire 6 into the anti-oxidation liquid 7 in the immersion tank 11 to start the anti-oxidation treatment process. The conveyor rollers 41 placed in the anti-oxidation liquid 7 can assist the copper wire 6 in being conveyed smoothly in the anti-oxidation liquid 7, ensuring that the copper wire 6 is in full contact with the anti-oxidation liquid 7 and improving the effect of anti-oxidation treatment. The second set of conveyor rollers 41 then leads the copper wire 6, which has completed the anti-oxidation treatment, out of the immersion tank 11 and sends it to the subsequent processing stage.

[0040] like Figure 6 As shown, the recycling mechanism 5 includes a recycling tank 51, a filter screen 52, and a recycling pipe 53. The immersion tank 11 is equipped with a recycling tank 51. The recycling tank 51 is equipped with a scraper 31 and a filter screen 52 in sequence along the conveying direction of the copper wire 6. The recycling tank 51 is equipped with a recycling pipe 53 on the outer side. The recycling pipe 53 is connected to the immersion tank 11.

[0041] The recovery tank 51 is used to collect the anti-oxidation liquid 7 scraped off by the scraper 31 and the anti-oxidation liquid 7 dripping from the surface of the copper wire 6. The filter screen 52 can filter the recovered anti-oxidation liquid 7 to remove any impurities and solid particles that may be present, ensuring the purity of the recovered anti-oxidation liquid 7 so that it can be recycled again. The recovery pipe 53 transports the filtered anti-oxidation liquid 7 back into the immersion tank 11, realizing the recycling of the anti-oxidation liquid 7, reducing production costs, and also reducing the discharge of waste liquid.

[0042] like Figure 7 As shown, the anti-oxidation device also includes a winding mechanism 8; The winding mechanism 8 includes a winding frame 81, a winding drum 82 and a motor 83. The winding frame 81 is equipped with a motor 83, and the output end of the motor 83 is equipped with a winding drum 82. The winding drum 82 and the winding frame 81 are rotatably connected. The winding frame 81 is placed on one side of the outlet of the immersion tank 11, and the winding drum 82 and the copper wire 6 are in contact.

[0043] The winding frame 81 provides a stable support platform for the winding drum 82 and the motor 83, ensuring that the winding mechanism 8 can work normally. The output torque of the motor 83 drives the winding drum 82 to rotate, and the copper wire 6, which has undergone anti-oxidation treatment and post-treatment, is evenly wound onto the winding drum 82. The contact method between the winding drum 82 and the copper wire 6 allows the copper wire 6 to be tightly wound on the winding drum 82, avoiding the copper wire 6 from becoming loose or messy during the winding process, ensuring the quality and neatness of the wound copper wire 6, and facilitating subsequent storage and transportation.

[0044] like Figure 1 As shown, the method includes the following steps: S1. The copper wire 6 is pulled through the anti-oxidation liquid 7 by the motor 83; S2. The copper wire 6 is pre-impregnated by the first roller 21 and the second roller 22; S3, scrape off the anti-oxidation liquid 7 brought out by the copper wire 6 that has just come out of the liquid through the scraper 31; S4. The thickness of the liquid film on the surface of the copper wire 6 is made uniform by using the air knife 32; S5. The copper wire 6 is wound up by the winding drum 82.

[0045] After the motor 83 starts, it drives the take-up drum 82 to rotate. The take-up drum 82 exerts a pulling force on the copper wire 6, causing the copper wire 6 to pass through each processing stage in sequence under the action of the conveying mechanism 4, and finally enter the anti-oxidation solution 7 in the immersion tank 11 to begin the anti-oxidation treatment process. Before entering the anti-oxidation solution 7, the copper wire 6 first contacts the first roller 21 and the second roller 22. Since the surfaces of the first roller 21 and the second roller 22 are covered with anti-oxidation solution 7, a small amount of anti-oxidation solution 7 is pre-covered on the surface of the copper wire 6 as it passes through, achieving pre-wetting. At the same time, it drives away and replaces the air on the surface of the copper wire 6, forming an initial liquid film and reducing the amount of bubbles generated after the copper wire 6 enters the anti-oxidation solution 7. When the copper wire 6 comes out of the anti-oxidation solution 7... A large amount of anti-oxidation liquid 7 will be carried out on the surface. At this time, the scraper 31 comes into contact with the copper wire 6 and scrapes off the excess anti-oxidation liquid 7 to prevent waste and dripping of the anti-oxidation liquid 7 from causing pollution to the equipment and the surrounding environment. Due to the gravity of the liquid film on the surface of the copper wire 6, the liquid film on the surface of the copper wire 6 after being treated by the scraper 31 may still be in a state of thin at the top and thick at the bottom. The airflow blown by the air knife 32 acts on the surface of the copper wire 6, which can automatically compensate for the thickness of the liquid film and form a uniform coating. At the same time, the low-pressure field generated by the airflow adsorbs the liquid film onto the surface of the copper wire 6, further improving the anti-oxidation treatment effect. Finally, the copper wire 6, which has completed the anti-oxidation treatment and post-treatment, is evenly wound up by the winding drum 82 under the drive of the motor 83, which facilitates subsequent storage and transportation.

[0046] Working principle of the invention: After the motor 83 starts, it drives the take-up drum 82 to rotate. The take-up drum 82 exerts a pulling force on the copper wire 6, causing the copper wire 6 to pass through each processing stage in sequence under the action of the conveying mechanism 4, and finally enter the anti-oxidation solution 7 in the immersion tank 11 to begin the anti-oxidation treatment process. Before entering the anti-oxidation solution 7, the copper wire 6 first contacts the first roller 21 and the second roller 22. Since the surfaces of the first roller 21 and the second roller 22 are covered with anti-oxidation solution 7, a small amount of anti-oxidation solution 7 is pre-covered on the surface of the copper wire 6 as it passes through, achieving pre-wetting. At the same time, it drives away and replaces the air on the surface of the copper wire 6, forming an initial liquid film and reducing the amount of bubbles generated after the copper wire 6 enters the anti-oxidation solution 7. When the copper wire 6 comes out of the anti-oxidation solution 7... A large amount of anti-oxidation liquid 7 will be carried out on the surface. At this time, the scraper 31 comes into contact with the copper wire 6 and scrapes off the excess anti-oxidation liquid 7 to prevent waste and dripping of the anti-oxidation liquid 7 from causing pollution to the equipment and the surrounding environment. Due to the gravity of the liquid film on the surface of the copper wire 6, the liquid film on the surface of the copper wire 6 after being treated by the scraper 31 may still be in a state of thin at the top and thick at the bottom. The airflow blown by the air knife 32 acts on the surface of the copper wire 6, which can automatically compensate for the thickness of the liquid film and form a uniform coating. At the same time, the low-pressure field generated by the airflow adsorbs the liquid film onto the surface of the copper wire 6, further improving the anti-oxidation treatment effect. Finally, the copper wire 6, which has completed the anti-oxidation treatment and post-treatment, is evenly wound up by the winding drum 82 under the drive of the motor 83, which facilitates subsequent storage and transportation.
