Description

[0002] In the production and processing of transformer outer shells, the painting process is a crucial link, which not only affects the appearance quality of the outer shell, but also has an important impact on the protection performance of the outer shell.

[0003] During the painting operation, some paint liquid will drip without adhering to the surface of the outer shell. The existing painting devices handle these unused paint liquids in a relatively rough manner, mostly allowing them to flow and drip freely, resulting in a large amount of waste of paint liquid. This not only increases the production cost, but also causes environmental pollution.

[0004] Although some devices are provided with simple recovery structures, although they use magnets to adsorb iron filings, the resin components in the paint liquid solidify on the surface of the magnets, forming an insulating barrier, and the magnets need to be disassembled and cleaned regularly to remove iron filings, seriously affecting the later production.

Detailed implementation manners

[0029] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] In one embodiment, as Figures 1 - 9 shown, a housing paint spraying device for transformer processing includes a processing table 1, a mobile vehicle 4 slides on the upper end of the processing table 1, a paint spraying box 2 is fixed in the middle of the upper end of the processing table 1, box doors 23 are slidably installed at both ends of the paint spraying box 2, a paint tank 5 is fixed in the middle of the lower end of the processing table 1, a liquid port 12 for communicating the inside of the paint spraying box 2 with the inside of the paint tank 5 is penetrated and opened in the middle of the upper end of the processing table 1, and a filter plate 121 is installed inside the liquid port 12; A fixed disk 3 is installed in the middle of the upper end of the spray painting box 2, and a spray painting structure 32 for extracting the paint liquid inside the paint box 5 is arranged on the fixed disk 3; Two material conveying pipes 54 are symmetrically fixed on both sides inside the paint box 5. Feed inlets 542 are opened at the upper ends of the material conveying pipes 54. A stirring structure 6 for preventing the paint liquid from solidifying is arranged on the outer wall of each material conveying pipe 54; The stirring structure 6 includes a connecting ring one 62 and a connecting ring two 63 rotatably installed at both ends of the outer wall of the material conveying pipe 54. Support rods 64 are evenly fixed on the outer walls of the connecting ring one 62 and the connecting ring two 63. The other ends of the two support rods 64 are fixed with a fixing plate 65. A plurality of magnetic rods 66 are evenly fixed at one end of the fixing plate 65 close to the material conveying pipe 54. A scraping member 67 for scraping the iron filings magnetically adsorbed on the outer wall of the magnetic rod 66 into the material conveying pipe 54 through the feed inlet 542 slides on the magnetic rod 66.

[0031] In this embodiment, the outer shell is placed on the mobile vehicle 4, and the mobile vehicle 4 transports the outer shell into the spray painting box 2. The box doors 23 at both ends of the spray painting box are closed to form a closed spray painting environment. The spray painting structure 32 extracts the paint liquid inside the paint box 5 and evenly sprays the paint liquid on the surface of the transformer outer shell. The stirring structure adsorbs the iron filings in the paint liquid through the magnetic rod 66, and the scraping member 67 scrapes the iron filings into the material conveying pipe 54 to prevent the paint liquid from solidifying.

[0032] In an alternative embodiment, the scraping member 67 includes two C-shaped rings 671 and a plurality of scraping rings 672. The two C-shaped rings 671 respectively slide on the support rods 64 on the outer walls of the connecting ring one 62 and the connecting ring two 63. A plurality of scraping rings 672 respectively slide on a plurality of magnetic rods 66. The inner wall of the scraping ring 672 is attached to the outer wall of the magnetic rod 66. The two C-shaped rings 671 and the adjacent two of the plurality of scraping rings 672 are fixed by connecting rods 673.

[0033] It should be noted that since the scraping ring 672 is closely attached to the outer wall of the magnetic rod 66, during the rotation of the magnetic rod 66, the scraping ring 672 can relatively slide along with the rotation of the magnetic rod 66, timely scraping off the impurities such as iron filings adsorbed on the magnetic rod 66, ensuring the continuous adsorption ability of the magnetic rod 66, and improving the impurity removal efficiency.

[0034] In an optional embodiment, the stirring structure 6 also includes a transmission wheel 61 rotatably mounted on the outer wall of the rear end of the paint box 5, a rotating rod 68 is fixed to one end of the transmission wheel 61 close to the paint box 5, the other end of the rotating rod 68 extends to the inside of the paint box 5 and is fixedly connected to the auger 7, the auger 7 is rotatably mounted inside the material transport pipe 54, the outer wall of the rotating rod 68 is fixedly connected to the connecting ring 1 62, the two transmission wheels 61 are connected by a belt 53, a motor 3 52 is installed at the rear end of the paint box 5, the output end of the motor 3 52 is fixedly connected to one of the transmission wheels 61, and discharge pipes 51 are symmetrically installed on both sides of the front end of the paint box 5, and each of the discharge pipes 51 is connected to the inside of a material transport pipe 54.

[0035] It should be noted that the rotating rod 68 transmits the power of the transmission wheel 61 to the auger 7 and the connecting ring 1 62 at the same time, so that the stirring action of the magnetic bar 66 is synchronized with the iron filings transportation action of the auger 7. While the magnetic bar 66 absorbs the iron filings, the auger 7 can transport the iron filings to the discharge pipe 51 for discharge in time, thereby improving the efficiency of impurity treatment.

[0036] In an optional embodiment, a plurality of leakage holes 541 are formed through the bottom end of the material conveying pipe 54 .

[0037] It should be noted that a plurality of leakage holes 541 are formed through the bottom of the material transport pipe 54 , which can discharge the paint liquid remaining in the material transport pipe 54 into the paint box 5 to prevent the paint liquid from accumulating in the material transport pipe 54 .

[0038] In an optional embodiment, a placement groove 41 is opened at the upper end of the mobile vehicle 4, and a plurality of leakage holes 42 are opened at the upper end of the placement groove 41. A convergence chamber 43 is opened inside the mobile vehicle 4, and a recovery pipe 44 is installed at the bottom of the convergence chamber 43. A solenoid valve 45 is installed on the recovery pipe 44. Moving wheels 46 are installed at the bottom corners of the mobile vehicle 4. Guide grooves 11 are symmetrically opened on both sides of the upper end of the processing table 1, and the guide grooves 11 correspond to the positions of the moving wheels 46. Side plates 13 are symmetrically fixed at both ends of the processing table 1.

[0039] It should be noted that by providing the placement slot 41, the leak hole 42, the convergence chamber 43 and the recovery pipe 44, the unattached paint liquid is effectively recovered. The coordinated design of the moving wheel 46 and the guide groove 11 enables the moving vehicle 4 to move flexibly on the processing table 1 while ensuring the stability of the movement. The setting of the side plate 13 limits the moving range of the moving vehicle 4, avoids the moving vehicle 4 from being offset or falling during the movement, and ensures the safety of the operator and the normal operation of the equipment.

[0040] In an alternative embodiment, the paint spraying structure 32 includes a liquid suction pump 322 installed at the upper end of the fixed disk 3. The liquid inlet end of the liquid suction pump 322 is connected to a liquid suction pipe 321, and the other end of the liquid suction pipe 321 extends to the bottom inside the paint tank 5. The liquid outlet end of the liquid suction pump 322 is connected to a liquid delivery pipe 323. The other end of the liquid delivery pipe 323 is rotatably connected to a fixed pipe 324. The lower end of the fixed pipe 324 is fixedly connected to a U-shaped paint spraying pipe 325. A plurality of atomizing nozzles 326 are installed at the paint spraying end of the U-shaped paint spraying pipe 325. A rotating structure 31 for driving the U-shaped paint spraying pipe 325 to rotate is provided on the fixed disk 3.

[0041] It should be noted that the liquid suction pump 322 directly extracts the paint liquid from the bottom of the paint tank 5 through the liquid suction pipe 321, ensuring the full utilization of the paint liquid. The liquid delivery pipe 323 stably delivers the paint liquid to the U-shaped paint spraying pipe 325, ensuring the continuity of the paint spraying process. The design of the U-shaped paint spraying pipe 325 combined with the drive of the rotating structure 31 enables the paint spraying pipe to rotate around the outer shell for spraying. The atomizing nozzles 326 uniformly atomize the paint liquid, further improving the uniformity of the paint spraying and ensuring the quality of the paint layer on the surface of the outer shell.

[0042] In an alternative embodiment, the rotating structure 31 includes a second motor 311 installed at the upper end of the fixed disk 3. The output end of the second motor 311 extends into the fixed disk 3 and is fixedly connected to a first gear 312. The first gear 312 is meshed with a second gear 313, and the second gear 313 is fixed to the fixed pipe 324.

[0043] It should be noted that driven by the second motor 311, the gear transmission can efficiently transmit power to the fixed pipe 324, enabling the U-shaped paint spraying pipe 325 to rotate stably. By controlling the rotation speed and direction of the second motor 311, the rotation speed and direction of the U-shaped paint spraying pipe 325 can be precisely controlled. This makes the paint spraying process more flexible, capable of adjusting the spraying angle and range according to actual needs, and improving the quality and efficiency of the paint spraying.

[0044] In an alternative embodiment, on both sides of the rear end of the paint spraying box 2, side openings one 21 are symmetrically provided. On both sides of the front end of the paint spraying box 2, side openings two 22 are symmetrically provided. At the front and rear ends of the box door 23, a second moving block 25 and a first moving block 24 are respectively fixed. The second moving block 25 slides with the side opening two 22, and the first moving block 24 slides with the side opening one 21. A sliding opening matching the box door 23 is provided at the upper end of the paint spraying box 2. A limiting plate 26 is fixed through the sliding opening at the upper end of the box door 23.

[0045] It should be noted that the side openings one 21 and the side openings two 22 provide accurate guidance for the movement of the box door 23, ensuring that the box door 23 always runs along a predetermined trajectory during the movement, enabling the box door 23 to be fully opened or closed, and ensuring the sealing performance of the paint spraying box 2.

[0046] In an alternative embodiment, the moving block 1-24 is threadedly connected to the screw rod 28, the lower end of the screw rod 28 is fixedly connected to the output end of the first motor 27, and the first motor 27 is mounted on the processing table 1.

[0047] It should be noted that by using the method of driving the screw rod 28 to rotate by the first motor 27, the automatic opening and closing of the box door 23 are realized. The operator only needs to control the start and stop of the first motor 27 to easily complete the operation of the box door 23, improving the work efficiency.

[0048] The above embodiment discloses an outer shell painting device for transformer processing. Among them, the transformer outer shell to be painted is placed in the placement groove 41 of the moving vehicle 4. The moving vehicle 4 moves in the guiding groove 11 at the upper end of the processing table 1 through the moving wheels 46 at the bottom, and transports the outer shell into the painting box 2.

[0049] Subsequently, the first motor 27 drives the screw rod 28 to rotate, so that the moving block 1-24 drives the box door 23 to slide downward along the edge 1-21, realizing the closing of the painting box 2, forming a closed painting environment, and preventing paint mist from leaking out and impurities from entering.

[0050] After that, the liquid extraction pump 322 extracts paint liquid from the interior of the paint tank 5 through the liquid extraction pipe 321. The paint liquid sequentially passes through the liquid delivery pipe 323, the fixed pipe 324, the U-shaped paint spraying pipe 325, and finally the paint liquid is evenly atomized and sprayed on the surface of the transformer outer shell through the atomizing nozzle 326.

[0051] Meanwhile, the second motor 311 drives the first gear 312 to drive the second gear 313 to rotate, and further drives the U-shaped paint spraying pipe 325 to rotate to make the paint spraying more uniform.

[0052] Then, the paint liquid that is not attached to the surface of the outer shell flows into the convergence cavity 43 through a plurality of first leakage holes 42 on the placement groove 41. At this time, the solenoid valve 45 is in a closed state. When the painting is completed, the solenoid valve 45 is opened, and the paint liquid passes through the recovery pipe 44 and passes through the liquid port 12 into the interior of the paint tank 5. The filter plate 121 on the liquid port 12 performs a primary filtration on the paint liquid.

[0053] The transmission wheel 61 rotates under the drive of the third motor 52, drives the rotating rod 68 to rotate, and the first connecting ring 62, the second connecting ring 63, the support rod 64, the fixing plate 65 and the magnetic rod 66 all rotate accordingly. The magnetic rod 66 adsorbs impurities such as iron filings in the paint liquid during the rotation process and stirs the paint liquid to prevent the paint liquid from solidifying.

[0054] The scraping member 67 slides on the magnetic rod 66, and scrapes the adsorbed iron filings into the material transporting pipe 54 through the feeding port 542, further ensuring the cleanliness of the paint liquid.

[0055] Specifically, when the magnetic rod 66 is located above the feeding port 542, the scraping member 67 slides downward under the influence of gravity, so that the scraping ring 672 scrapes the iron filings magnetically adsorbed on the outer wall of the magnetic rod 66 into the material conveying pipe 54.

[0056] The rotating rod 68 drives the auger 7 inside the material conveying pipe 54 to rotate. The auger 7 transports the iron filings to the discharge pipe 51, and the iron filings will finally be discharged through the discharge pipe 51. The leakage hole two 541 at the bottom of the material conveying pipe 54 discharges the paint liquid inside it into the paint tank 5.

[0057] As described above, it is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art within the technical scope disclosed in this application can easily think of changes or substitutions, which should all be covered within the protection scope of this application. Therefore, the protection scope of this application shall be subject to the protection scope of the claims.
