[0002] Dry-type transformers are widely used in places such as local lighting, high-rise buildings, airports, docks, and CNC machinery equipment. Simply put, a dry-type transformer refers to a transformer in which the iron core and windings are not impregnated in insulating oil; baking paint for dry-type transformers is an important link in its manufacturing process, which involves the painting and drying processes of the transformer shell and internal components.

[0003] In Chinese Invention Publication No. CN215695122U, an automatic baking paint device for high-frequency transformer processing is proposed. It sprays the transformer on the rotating disk in a reciprocating, balanced, and multi-angle manner through a spray gun, greatly improving the work efficiency. While spraying, the heating tube is electrically connected to the power supply through a controller, and the heating tube starts to heat up, heating the surrounding air, and quickly drying the transformer sprayed inside the protective cover of the baking paint device, greatly improving the work efficiency.

[0004] Combined with the existing technology, in the process of implementing the present application, the inventor found that there are at least the following problems in this technology. The transformer is sprayed at multiple angles by reciprocating the spray gun. However, the shapes of existing dry-type transformers are relatively variable, and it is easy to overlook details such as the corners of dry-type transformers when spraying by reciprocating the spray gun, resulting in poor touch-up painting effects. At the same time, during the spraying process of dry-type transformers, one side is blocked, and it is necessary to stop the machine and restart to change the surface for the painting process, resulting in poor baking paint efficiency. Therefore, a baking paint device for dry-type transformer processing is proposed to solve the above problems. Content of the Utility Model

Detailed implementation manners

[0017] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3 , a baking paint device for dry-type transformer processing in this embodiment includes a base 1. A roller conveyor 2 is arranged on the top of the base 1. A protective mechanism is arranged outside the base 1, a paint spraying mechanism is arranged inside the protective mechanism, and a flipping mechanism is arranged inside the protective mechanism.

[0019] Among them, the setting of the roller conveyor 2 enables the dry-type transformer to be conveniently transported for baking paint processing.

[0020] It should be noted that the whole device is applicable to but not limited to the baking paint processing of dry-type transformers.

[0021] In this embodiment, the paint spraying mechanism includes a horizontal linear motor 10. The horizontal linear motor 10 is arranged inside the protective mechanism. A telescopic cylinder 11 is fixedly installed at the output end of the horizontal linear motor 10. A vertical linear motor 12 is fixedly installed at the output end of the telescopic cylinder 11. A bearing seat 13 is fixedly installed at the output end of the vertical linear motor 12. A servo motor 14 is fixedly installed inside the bearing seat 13. A support frame 15 is fixedly installed at the output end of the servo motor 14. Two paint spray guns 16 are fixedly installed outside the output end of the support frame 15.

[0022] Specifically, after the roller conveyor 2 transports the dry-type transformer into the protective mechanism from the rear side, starting the horizontal linear motor 10 can adjust the left and right movement of the paint spray gun 16. Adjusting the telescopic cylinder 11 can make the paint spray gun 16 move back and forth. Adjusting the vertical linear motor 12 can adjust the painting height of the paint spray gun 16. Starting the servo motor 14 can adjust the horizontal spraying orientation of the paint spray gun 16. Thus, by cooperating with each other, the paint spray gun 16 can flexibly spray paint on the outside of the dry-type transformer.

[0023] It should be noted that a connection port is provided outside the paint spray gun 16, and it is connected to an external paint pump through a telescopic hose to quickly suck and spray the paint.

[0024] In this embodiment, the protection mechanism includes a protection bin 3, which is fixedly installed outside the base 1. Feeding and discharging holes 4 are formed in both the front and back of the protection bin 3. Two linear guide rails 5 are fixedly installed on both the left and right sides of the protection bin 3. The output ends of the front and rear linear guide rails 5 are fixedly installed with movable doors 6. The movable doors 6 are located outside the feeding and discharging holes 4. Hydraulic push rods 7 are fixedly installed on both the left and right sides of the protection bin 3. The output ends of the hydraulic push rods 7 are fixedly connected to the movable doors 6. An exhaust pipe 8 is communicated with the rear end of the top of the protection bin 3, and a transportation pipe 9 is communicated with the front end of the top of the protection bin 3.

[0025] It should be noted that the exhaust pipe 8 is connected to an external exhaust fan to suck and discharge the waste gas generated by the baking paint. The transportation pipe 9 is connected to an external hot air blower to allow hot air to enter and dry the paint on the surface of the dry-type transformer.

[0026] Specifically, after the roller conveyor 2 sends the dry-type transformer into the protection bin 3 through the rear feeding and discharging hole 4, the hydraulic push rod 7 is started to drive the movable door 6 to move on the linear guide rail 5, so that the movable door 6 tries to block the feeding and discharging hole 4 and is infinitely close to the roller conveyor 2, thereby blocking the spilled paint and harmful gases during the baking paint process.

[0027] In this embodiment, the flipping mechanism includes a reduction motor 17, which is fixedly installed on the left side of the protection bin 3. The output end of the reduction motor 17 is fixedly installed with a rotating shaft 18 whose one end is rotatably connected to the protection bin 3. An adjusting plate 19 is fixedly installed on the back of the rotating shaft 18. A baffle 21 is hinged to the top of the rotating shaft 18. Adjusting cylinders 20 whose one ends are hinged to the baffle 21 are hinged to both the front and back of the adjusting plate 19. The adjusting plate 19 is located inside the roller conveyor 2, and a transverse linear motor 10 is fixedly installed on the rear side of the inner wall of the protection bin 3.

[0028] Specifically, after the roller conveyor 2 delivers the dry-type transformer into the protective bin 3 through the rear inlet and outlet hole 4, after the dry-type transformer is sprayed and painted on the outside, the adjusting cylinder 20 is started to extend so that the baffle 21 rotates forward vertically with the hinge of the rotating shaft 18 as the center. At this time, the roller conveyor 2 is started again to move the dry-type transformer to the adjusting plate 19 and contact the baffle 21. Then, the reduction motor 17 is started to rotate the rotating shaft 18, thereby driving the adjusting plate 19 and the baffle 21 to rotate and drive the dry-type transformer inside to flip, so that the other side contacts the roller conveyor 2 and is transported to the front side of the baffle 21. Then, the paint spraying mechanism and the protective mechanism are used to paint and paint the shielding surface of the dry-type transformer. Finally, after the painting is completed, the hydraulic push rod 7 is started to open the movable door 6, so that the roller conveyor 2 drives the dry-type transformer to move forward and leave the protective bin 3.
