The outer wall of the sliding plate 8 is slidably connected to the inner wall of the drying chamber 1. The inside of the sliding plate 8 is slidably connected to a sliding column 9. The outer wall of the sliding column 9 is fixedly connected to the inside of the drying chamber 1. The outer wall of the drying chamber 1 is provided with a protective component for protecting the internal structure of the drying chamber 1. The protective component includes a door 10. The outer wall of the door 10 is slidably connected to the outer wall of the drying chamber 1. The outer wall of the door 10 is fixedly connected to a handle 11. A viewing window 12 is opened inside the door 10.
[0024] Specifically, the fixing plate 2 is fixed to the outer wall of the drying chamber 1 to fix the first motor 3. The first motor 3 enables the conveyor belt 5 to rotate through the rotation of the first roller 4, which in turn drives the second roller 6 to rotate. The fixing plate 2 and the drying chamber 1 respectively support the first roller 4 and the second roller 6, allowing them to rotate stably. The second roller 6 fixes the threaded column 7. The drying chamber 1 supports the threaded column 7, which in turn rotates through the rotation of the second roller 6, thereby driving the slide plate 8 to slide through the threads. The slide plate 8 serves to hold the metering voltage transformer. The sliding column 9 is fixed inside the drying chamber 1 to provide auxiliary support for the sliding of the slide plate 8, allowing it to slide stably. The handle 11 is fixed to the outer wall of the chamber door 10, which can be pulled to quickly open the chamber door 10. The chamber door 10 serves to isolate external impurities. The status of the metering voltage transformer can be observed in real time through the viewing window 12.
[0025] Reference Figure 2 and Figure 4 A second motor 13 is fixedly connected inside the drying oven 1. A rotating shaft 14 is fixedly installed at the output end of the second motor 13. A bracket 15 is rotatably connected to the outer wall of the rotating shaft 14. The outer wall of the bracket 15 is fixedly connected to the inside of the drying oven 1. A rotating block 16 is fixedly connected to the outer wall of the rotating shaft 14. A connecting shaft 17 is rotatably connected inside the rotating block 16. A rotating column 18 is fixedly connected to the outer wall of the connecting shaft 17. A first fixed shaft 19 is fixedly connected to the outer wall of the rotating column 18. A rotating frame 20 is rotatably connected to the outer wall of the first fixed shaft 19.
[0026] Specifically, the drying chamber 1 serves to fix the second motor 13, which enables the rotating block 16 to rotate via the rotation of the rotating shaft 14. The bracket 15 is fixed inside the drying chamber 1 to provide stable support for the rotation of the rotating shaft 14. The connecting shaft 17 connects the rotating block 16 and the rotating column 18, allowing the rotating column 18 to rotate via the rotation of the rotating block 16. The first fixed shaft 19 connects the rotating column 18 and the rotating frame 20, thereby enabling the rotating frame 20 to rotate via the rotation of the rotating column 18.
[0027] Reference Figure 4 The outer wall of the rotating frame 20 is fixedly connected to a second fixed shaft 21, and the outer wall of the second fixed shaft 21 is rotatably connected to the inside of the bracket 15. The outer wall of the rotating column 18 is fixedly connected to a connecting rod 22, and a fan 23 is provided on the outer wall of the connecting rod 22.
[0028] Specifically, the second fixed shaft 21 connects the rotating frame 20 and the support 15, allowing the rotating frame 20 to rotate stably via the second fixed shaft 21. The connecting rod 22 connects the rotating column 18 and the fan 23, allowing the fan 23 to rotate via the rotation of the rotating column 18, thus uniformly drying the insulating varnish on the surface of the metering voltage transformer.
[0029] Reference Figure 2 The drying oven 1 is equipped with a heating plate 24.
[0030] Specifically, the temperature inside the drying oven 1 can be adjusted by the design of the heating plate 24, and the drying process can be accelerated by temperature control.
[0031] Working principle: When the device is needed, pull handle 11 to open the door 10. Adjust the height of the slide plate 8 according to the different sizes and heights of the metering voltage transformers. Start the first motor 3. The first motor 3 drives the conveyor belt 5 through the first roller 4. The conveyor belt 5 drives the second roller 6 on the inner wall to rotate. The rotation of the second roller 6 causes the threaded column 7 to rotate. During the rotation of the threaded column 7, the slide plate 8 slides on the inner wall of the drying chamber 1 through the sliding column 9, adjusting the height of the slide plate 8 inside the drying chamber 1. Place the metering voltage transformer on the upper surface of the slide plate 8 for drying treatment, achieving the effect of adjusting the optimal drying position according to different models of metering voltage transformers, improving drying efficiency and drying quality. Start the second motor 13 to drive the rotating block 16 to rotate through the rotating shaft 14. The rotating block 16 rotates, causing the connecting shaft 17 and the rotating column 18 to rotate simultaneously. During the rotation of the rotating column 18, the rotating frame 20 can be driven to rotate via the first fixed shaft 19. The rotation of the rotating frame 20 can drive the second fixed shaft 21 to rotate, thereby driving the connecting rod 22 and the fan 23 to rotate simultaneously, thus rotating and drying the metering voltage transformer. The temperature inside the drying chamber 1 can be adjusted by the heating plates 24 on both sides of the drying chamber 1, accelerating the drying process of the metering voltage transformer. This achieves the effect of blowing hot air evenly onto the surface of the insulating varnish, avoiding local overheating or uneven drying. This device can not only achieve the effect of adjusting the optimal drying position according to different models of metering voltage transformers, improving drying efficiency and drying quality, but also achieve the effect of blowing hot air evenly onto the surface of the insulating varnish, ensuring uniform drying.
