Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, and in particular to a transformer impregnation device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil, and iron core. In electrical equipment and wireless circuits, it is commonly used for voltage step-up and step-down, impedance matching, and safety isolation. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. During the production process, transformer components need to be impregnated with varnish to improve the transformer's insulation and moisture-proof performance.

[0003] However, during the current process of impregnating transformer components with paint, they are moved to another workstation for drying. During this process, undried paint drips down, requiring time to clean up, which affects the work speed. Furthermore, the process of moving components requires a lot of manpower, which is time-consuming and labor-intensive.

[0004] Therefore, a transformer impregnation device is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To overcome the shortcomings of existing technologies, a transformer impregnation device is proposed to solve the problems of reduced work efficiency and high manpower consumption, time and labor costs associated with moving and drying transformer components during the impregnation process.

[0007] (II) Technical Solution

[0008] This utility model is achieved through the following technical solution: This utility model proposes a transformer production varnish impregnation device, including an impregnation tank, and a controller is installed on the outside of the impregnation tank.

[0009] The interior of the paint impregnation tank is divided into an upward-through-through paint impregnation chamber, a dripping chamber, and a drying chamber by an internal partition.

[0010] A movable frame is mounted across the top of the impregnation tank, and a movable mechanism is installed on the side end face of the impregnation tank to enable the movable frame to move left and right. A first electric push rod is installed at the top of the movable frame, and a lifting cover plate is installed and connected through the output end of the first electric push rod through the movable frame. A mounting frame is rotatably installed at the bottom end of the lifting cover plate.

[0011] An air pipe is installed on the inner wall of the drying chamber, and several air nozzles are provided on the inner side of the air pipe. A hot air blower is installed on the outer side of the paint impregnation box and connected to the air inlet of the air pipe.

[0012] Furthermore, the moving mechanism includes symmetrically arranged moving slides inside both sides of the impregnation tank. Positioning slide rods and lead screws are respectively installed inside the moving slides, and the lead screws are rotatably connected to the moving slides through bearings. Moving sliders are connected to the bottom ends of both sides of the moving frame, and the moving sliders on both sides are respectively provided with positioning slide holes and threaded holes to connect with the positioning slide rods and lead screws. A motor is installed on the outside of the impregnation tank and connected to one side of the lead screw.

[0013] Furthermore, the lifting cover is provided with fixing plates on both sides of the bottom end, and fixing rods are symmetrically provided on the inner side of the fixing plates. A rotating plate is connected to the upper end of the mounting frame, and a rotating hole is provided in the middle of the rotating plate to be rotatably connected to the fixing rod.

[0014] Furthermore, push plates are symmetrically installed at both ends of the inner walls of the impregnation chamber, dripping chamber, and drying chamber, and a second electric push rod is installed on the outside of the impregnation tank and connected to the push plates.

[0015] Furthermore, the placement frame is divided into several layers, and each layer has a retrieval opening at its top.

[0016] Furthermore, the bottom of the impregnation chamber, the dripping chamber, and the drying chamber are all provided with through outlets.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model has the following advantages:

[0019] 1. In this utility model, by setting up an impregnation chamber, a dripping chamber, and a drying chamber inside the impregnation tank, and by having the lower end of the placement frame move up and down with the first electric push rod, the transformer components can be quickly moved into the dripping chamber or drying chamber after impregnation. This avoids the situation where manual repositioning causes paint to drip during the repositioning process, wasting subsequent cleaning time, and saves manpower, time, and costs, resulting in faster work efficiency and better work results.

[0020] 2. In this utility model, by pulling the placement frame to the upper end of the dripping chamber, it is convenient to drip the paint inside, preventing the paint from dripping outside and causing subsequent cleaning time to be wasted. When the placement frame is placed inside the drying chamber, the hot air blows air into the inside through the air pipe and jet nozzle, drying the transformer components inside the placement frame. This avoids the low efficiency of natural air drying, making the working speed faster and accelerating the drying rate.

[0021] 3. In this utility model, push plates are symmetrically arranged inside the impregnation chamber, dripping chamber and drying chamber. Under the push of the second electric push rod, the push plates push the mounting frame back and forth, causing the internal transformer component to shake under the rotation of the top of the mounting frame. This makes the transformer component more effective in impregnation, accelerates the dripping speed, and speeds up the drying rate when dried by air blowing, resulting in better working effect.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0029] Please see Figure 1 and Figure 4This utility model provides a transformer impregnation device, including an impregnation tank 1. A controller 114 is installed on the outside of the impregnation tank 1, which can be used to operate the electrical components in the device, making the operation simpler and more convenient. The impregnation tank 1 is divided into an upward-through impregnation chamber 2, a dripping chamber 3, and a drying chamber 4 by an internal partition. The impregnation chamber 2 is used for impregnation, while the dripping chamber 3 can collect the dripping paint to avoid wasting time and slowing down the work. The drying chamber 4 is used to dry the transformer components. The bottom of the impregnation chamber 2, the dripping chamber 3, and the drying chamber 4 are all provided with through outlets 5, which facilitate the replacement of paint in the impregnation chamber 2 and drain the accumulated paint in the dripping chamber 3 and the drying chamber 4.

[0030] Please see Figure 1 , Figure 2 and Figure 3A movable frame 6 is mounted across the top of the impregnation tank 1, arranged in a U-shape to facilitate the retrieval of transformer components from both sides. A moving mechanism is installed on the side face of the impregnation tank 1 to allow the movable frame 6 to move left and right. The moving mechanism includes symmetrically arranged sliding grooves 19 on both sides of the impregnation tank 1. Positioning slide rods 110 and lead screws 111 are respectively installed inside the sliding grooves 19, with the lead screws 111 rotatably connected to the sliding grooves 19 via bearings. Movable sliders 112 are connected to the bottom ends of both sides of the movable frame 6, and each sliding slider 112 has positioning holes and threaded holes for connecting to the positioning slide rods 110 and lead screws 111. The connection, through the sliding connection between the positioning sliding hole and the positioning sliding rod 110, enhances the stability of one side of the moving frame 6, making it more effective during movement. A motor 113 is installed on the outside of the impregnation tank 1, connected to one side of the lead screw 111. When the motor 113 drives the lead screw 111 to rotate, it drives the moving slider 112 through the threaded hole, pushing the moving frame 6 to move, thus realizing the left and right movement of the placement frame 9. This avoids manual movement, saves manpower, and improves work efficiency. A first electric push rod 7 is installed at the top of the moving frame 6, and a lifting cover plate is installed and connected to the output end of the first electric push rod 7 through the moving frame 6. 8. The lifting cover 8 can cover the upper ends of the impregnation chamber 2, the dripping chamber 3, and the drying chamber 4, reducing splashing during impregnation. Multiple air holes are provided in the lifting cover 8 to facilitate exhaust during air blowing in the drying chamber 4, resulting in better drying. A mounting frame 9 is rotatably mounted at the bottom of the lifting cover 8. The mounting frame 9 is filter-type, facilitating the impregnation of internal transformer components. The mounting frame 9 is divided into several layers to accommodate more transformer components, allowing for more components to be impregnated at once, resulting in better impregnation. Each layer has a pick-and-place opening 10 at its top. This design places the retrieval port 10 at the top, preventing it from slipping outwards during pushing and shaking, thus improving safety and facilitating the retrieval of the internal transformer components by staff. The bottom of the lifting cover 8 has two fixing plates 11 on either side, with symmetrical fixing rods 12 on the inner side of each fixing plate 11. A rotating plate 13 is connected to the upper end of the mounting frame 9, and the rotating plate 13 has a rotating hole in the middle that rotatably connects to the fixing rods 12. This allows the mounting frame 9 to rotate to both sides under force, with a fixed left and right rotation direction, preventing rotation on the other sides and improving safety during shaking. This also facilitates the pushing and shaking action of the lower push plate 14.

[0031] Preferably, push plates 14 are symmetrically installed at both ends of the inner walls of the impregnation chamber 2, the dripping chamber 3, and the drying chamber 4. A second electric push rod 18 is installed on the outside of the impregnation tank 1 and connected to the push plate 14. The push plate 14 inside the impregnation chamber 2 is pushed inward by the second electric push rod 18 to rotate the mounting frame 9, causing the transformer component inside the mounting frame 9 to shake under force, thus improving the impregnation effect. Furthermore, the shaking of the mounting frame 9 under the action of the push plate 14 in the dripping chamber 3 can accelerate the dripping rate when the paint is dripping, thus increasing the working efficiency. The shaking of the mounting frame 9 under the force of the push plate 14 inside the drying chamber 4 can cause the transformer component to shake, resulting in better air drying during the shaking process, accelerating the paint drying rate, and thus improving the working effect.

[0032] Please see Figure 1 and Figure 2 An air pipe 15 is installed on the inner wall of the drying chamber 4, and several air nozzles 16 are provided on the inner side of the air pipe 15. A hot air blower 17 is installed on the outside of the paint impregnation box 1 and connected to the air inlet of the air pipe 15. The hot air blows hot air into the interior of the drying chamber 4 through the air pipe 15 and the air nozzles 16, so that the hot air can accelerate the drying of the paint on the transformer components when passing through the mounting frame 9, avoiding the low efficiency of natural air drying, and making the overall work efficiency higher.

[0033] Working principle: In use, first connect the first electric push rod 7, hot air blower 17, second electric push rod 18, motor 113, and controller 114, and connect them to an external power supply. Then, place the transformer component into the inner layer of the mounting frame 9 through the pick-up port 10. Under the push of the first electric push rod 7, the mounting frame 9 is placed into the impregnation chamber 2 for impregnation. The second electric push rod 18 pushes the push plate 14 back and forth at intervals, causing the mounting frame 9 to rotate at the top, thus shaking the transformer component and improving the efficiency of impregnation. Afterward, the first electric push rod 7 pulls the lifting cover plate 8 to remove the mounting frame 9 upward. When the motor 113 drives the lead screw 111 to rotate, the movable slider 112 is forced to move the movable frame 6, which in turn moves the placement frame 9. This causes the lower placement frame 9 to move to the upper end of the dripping chamber 3 for mechanical dripping. Depending on the needs, the internal push plate 14 can be activated to accelerate the dripping rate. Then, the placement frame 9 is moved to the upper end of the drying chamber 4 and placed inside. The hot air blower 17, through the air pipe 15 and the air nozzle 16, quickly dries the transformer components inside the placement frame 9. The working speed can be accelerated by pushing the internal push plate 14. Finally, the transformer components are removed, thus completing the work.
