[0002] Arc spraying technology is an important branch of thermal spraying technology in the emerging surface engineering discipline, and it is also a new technology for surface protection and strengthening of materials. Arc spraying uses the arc burning between two continuously fed metal wires to melt the metal, atomizes the melted metal with a high-speed air flow, and accelerates the atomized metal particles to spray them onto the workpiece to form a coating. It has unique advantages in preparing anti-corrosion coatings, wear-resistant coatings, high-temperature oxidation-resistant coatings, electrical conductivity and electromagnetic shielding coatings, dimension restoration coatings, decorative coatings, and other special functional coatings.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1-4 , the present invention provides a technical solution: an arc spraying device for zinc-copper-titanium alloy wire, including a spray gun 1, a protective cover 2 is sleeved on one side of the spray gun 1, an air inlet duct 5 is communicated with one side of the protective cover 2, the other end of the air inlet duct 5 is provided with a collection assembly 3, and an auxiliary cleaning assembly 4 is arranged on one side of the collection assembly 3;

[0035] ​The collection component 3 includes a fixed box 301. One side of the fixed box 301 is fixedly connected to the spray gun 1. On one side inside the fixed box 301, a vertical plate 302 is fixedly connected. On one side of the vertical plate 302, a horizontal plate 303 is fixedly connected. Below the horizontal plate 303, a collection box 305 is arranged. On the top of the horizontal plate 303, a filter screen 304 is fixedly connected. On one side of the filter screen 304, a driving motor 306 is arranged. The driving motor 306 is fixedly connected inside the fixed box 301 through a support frame. The output shaft of the driving motor 306 is fixedly connected to a second rotating shaft, and the other end of the second rotating shaft is fixedly connected to a fan blade 307.

[0036] The specific implementation method is as follows: Connect the spray gun 1 to an external power supply, supply power to the conductive nozzle through the built-in power supply of the spray gun 1, and then heat the zinc-copper-titanium alloy wire. Then, supply air to it through an external compressed air supply device, and evenly spray the melted zinc-copper-titanium alloy wire solution on the surface of the external workpiece to form a coating on the workpiece surface. At this time, start the driving motor 306 to drive the second rotating shaft to rotate, and use the second rotating shaft and the fan blade 307 to rotate to make the inside of the fixed box 301 in a negative pressure state. At this time, the fixed box 301 extracts the metal powder generated during spraying through the air inlet pipe 5 connected on one side, preventing the metal powder from being directly discharged into the air, which is likely to affect the surrounding environment and further prevent the impact on the physical health of the users. The powder is filtered through the set filter screen 304. Since the zinc-copper-titanium alloy wire is sprayed after heating, the gas extracted into the fixed box 301 contains heat and irritating gases. At this time, the gas is transported to the inside of the liquid storage tank 309 through the air delivery pipe 308, and the liquid inside the liquid storage tank 309 is used for auxiliary heat dissipation, and at the same time, the gas is filtered again to prevent the gas from being directly discharged into the air and affecting the surrounding working environment. The gas after heat dissipation and filtration is transported to the second inner cavity opened in the arc-shaped block 311 through the air outlet pipe 310, and then sprayed on the workpiece surface through the air outlet 312, which is convenient for auxiliary cooling of the coating on the workpiece surface without waiting for the coating to naturally cool and form, thus improving the spraying efficiency.

[0037] On the side of the vertical plate 302 facing away from the horizontal plate 303, an air delivery pipe 308 is connected. The other end of the air delivery pipe 308 is provided with a liquid storage tank 309. The bottom of the liquid storage tank 309 is fixedly connected to the inner side wall of the fixed box 301. One side of the top of the liquid storage tank 309 is connected to an air outlet pipe 310. The other end of the air outlet pipe 310 extends to the outside of the fixed box 301 and is provided with an arc-shaped block 311. The arc-shaped block 311 is fixedly connected to the outer side wall of the protective cover 2. A second inner cavity is opened inside the arc-shaped block 311. One side of the inner part of the second inner cavity is connected to a plurality of air outlet holes 312. The auxiliary cleaning component 4 includes a fixed block 401. One side of the fixed block 401 is fixedly connected to the fixed box 301. A second inner cavity is opened inside the fixed block 401. An incomplete gear 404 is arranged inside the second inner cavity. A first rotating shaft 403 is sleeved inside the incomplete gear 404. The top end of the first rotating shaft 403 extends into the air inlet pipe 5 and is sleeved with an inclined blade 402.

[0038] The specific implementation method is as follows: For the gas that simultaneously enters the inside of the fixed box 301, its fluidity drives the inclined blade 402 and the first rotating shaft 403 to rotate. By using the linkage effect between the first rotating shaft 403 and the incomplete gear 404, the power is transmitted to the incomplete gear 404, so that the incomplete gear 404 drives the rack 405 to move, and further enables the connecting block 406 and the cleaning brush 407 to move, for on-line cleaning of the filter screen 304, preventing the filter screen 304 from being blocked and affecting the use of the product, reducing the maintenance time of the product, and ensuring the sustainable use of the product.

[0039] One side of the incomplete gear 404 is meshed and connected with a rack 405. The other side of the rack 405 is fixedly connected with a connecting block 406. The other side of the connecting block 406 extends into the inside of the fixed box 301 and is fixedly connected with two cleaning brushes 407. The connecting block 406 is slidably connected in the first through hole opened in the fixed box 301 and the fixed block 401. Air bags 409 are fixedly connected to both sides of the connecting block 406. The other side of the air bags 409 is fixedly connected to the inner side wall of the first through hole. One side of the air bags 409 is connected to a first connecting pipe. The other side of the air bags 409 is connected to a second connecting pipe. One-way valves are arranged on both the first connecting pipe and the second connecting pipe. The other end of the second connecting pipe is connected to the second inner cavity opened in the arc-shaped block 311. One side of the rack 405 is fixedly connected with a spring 408. The other side of the spring 408 is fixedly connected to the inner side wall of the fixed block 401. The bottom of the rack 405 is fixedly connected with a slider. The other side of the slider is slidably connected with a slide rail. The other side of the slide rail is fixedly connected to the inner side wall of the fixed block 401. The other side of the horizontal plate 303 is fixedly connected to the inner side wall of the fixed box 301. A second through hole is opened on one side of the inside of the horizontal plate 303. One side below the fixed box 301 is rotatably connected with a door panel through a hinge.

[0040] The specific implementation method is as follows: while the connecting block 406 moves, it will squeeze the airbag 409, and the gas inside the airbag 409 is transported through the second connecting pipe to the second inner cavity opened in the arc-shaped block 311, which further improves the cooling efficiency of the workpiece surface coating. By setting the airbag 409, it prevents metal powder from entering the first inner cavity opened in the fixed block 401, further ensuring the service performance of the product.

[0041] Working principle: When in use, connect the spray gun 1 to an external power supply, and supply power to the nozzle through the built-in power supply of the spray gun 1, thereby heating the zinc-copper-titanium alloy wire. Then, supply air to it through an external compressed air supply device, and evenly spray the melted zinc-copper-titanium alloy wire solution on the surface of the external workpiece to form a coating on the workpiece surface. At this time, start the driving motor 306 to drive the second rotating shaft to rotate, and use the second rotating shaft and the fan blade 307 to rotate to make the inside of the fixed box 301 in a negative pressure state. At this time, the fixed box 301 extracts the metal powder generated during spraying through the air inlet pipe 5 connected to one side, and filters its powder through the set filter screen 304. Since the zinc-copper-titanium alloy wire is sprayed after being heated, the gas extracted into the fixed box 301 contains heat and irritating gases. At this time, the gas is transported to the inside of the liquid storage tank 309 through the air delivery pipe 308, and the liquid inside the liquid storage tank 309 is used for auxiliary heat dissipation and secondary filtration. The gas after heat dissipation and filtration is transported to the second inner cavity opened in the arc-shaped block 311 through the air outlet pipe 310, and then sprayed on the workpiece surface through the air outlet 312, which is convenient for auxiliary cooling of the coating on the workpiece surface. At the same time, for the gas entering the inside of the fixed box 301, its fluidity will drive the inclined blades 402 and the first rotating shaft 403 to rotate. Using the linkage effect between the first rotating shaft 403 and the incomplete gear 404, the power is transmitted to the incomplete gear 404, so that the incomplete gear 404 drives the rack 405 to move, and further makes the connecting block 406 and the cleaning brush 407 move to clean the filter screen 304 online. While the connecting block 406 moves, it will squeeze the airbag 409, and the gas inside the airbag 409 is transported through the second connecting pipe to the second inner cavity opened in the arc-shaped block 311, which further improves the cooling efficiency of the workpiece surface coating.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
