[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present application.
[0023] The embodiments of the present application provide a paint spraying and drying device for transformer production. This paint spraying and drying device for transformer production can keep the distance between the paint spray head and the surface of the insulating cylinder during jet spraying through a distance fixing component, avoid uneven thickness of the paint film, improve the paint spraying effect, reduce repetitive labor, eliminate the need for multiple paint replenishments or corrections, and also eliminate the need for manual paint spraying, thus greatly improving the paint spraying efficiency.
[0024] The following provides a detailed description of this paint spraying and drying device for transformer production. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.
[0025] The present application will be described in detail below in conjunction with the accompanying drawings and specific implementation manners. Embodiment
[0026] Please refer to Figures 1-7 In, a paint spraying and drying device for transformer production provided in this embodiment includes: a box body 1, an electric slide rail 11 is fixedly installed at the top inside the box body 1, a connecting plate 12 is fixedly installed at the bottom of the slide table of the electric slide rail 11, an air box 13 is fixedly connected to the top of the box body 1, and a distance fixing component is arranged on the connecting plate 12 for spraying paint on the insulating cylinder of the dry-type transformer.
[0027] During use, the electric slide rail 11 can drive the connection plate 12 to move, drive the distance - determining component to move, so as to control the distance - determining component to fit the surface of the insulating cylinder of the dry - type transformer, and keep the painting distance constant through the distance - determining component, avoiding affecting the painting quality. Embodiment
[0028] On the basis of Embodiment 1, the distance - determining component includes: mounting plates 2 are fixedly connected to the circumferential side of the connection plate 12. A plurality of cylinders 21 are fixedly installed on one side of the mounting plate 2. Telescopic rods 22 are respectively slidably connected inside the cylinders 21. One end of the telescopic rod 22 far from the cylinder 21 is fixedly connected with a fixing block 23. An inverted L - shaped plate 24 is fixedly connected to one side of the fixing block 23. A number of paint spray heads 25 are fixedly installed on the side of the L - shaped plate 24 far from the mounting plate 2. The number of paint spray heads 25 is evenly distributed. A spring 26 is connected between one end of the telescopic rod 22 and the cylinder 21. The other end of the telescopic rod 22 is fixedly connected with a connection block 27. A roller 28 is rotatably connected inside the connection block 27.
[0029] During painting, the electric slide rail 11 is controlled through the control panel on one side of the box body 1, so that the box body 1 controls the connection plate 12 to approach the insulating cylinder, making the roller 28 fit the surface of the insulating cylinder. Then move a further distance, so that the telescopic rod 22 is pushed into the inside of the cylinder 21. When the telescopic rod 22 moves, it will drive the fixing block 23, the connection block 27 and the roller 28 to move. The fixing block 23 drives the L - shaped plate 24 to move. At the same time, the telescopic rod 22 compresses the spring 26, and the spring 26 is compressed and stores energy when being squeezed. When spraying, the paint spray heads 25 are opened, and the paint is sprayed out from the paint spray heads 25. The external part is sprayed in cooperation with the slow rotation of the insulating cylinder. The roller 28 moves along the undulation on the circumferential side of the insulating cylinder. When moving, the telescopic rod 22 extends or retracts under the influence of the undulation arc on the circumferential side. When the roller 28 moves to a wider part of the insulating cylinder, the telescopic rod 22 is further pushed into the inside of the cylinder 21, and the spring 26 is further compressed. When the roller 28 moves to a narrower part of the insulating cylinder, the telescopic rod 22 is pushed out of the inside of the cylinder 21 under the action of the spring 26, making the roller 28 fit the outside of the insulating cylinder. In this way, the paint spray heads 25 always keep the same distance from the outside of the insulating cylinder, so that the paint on the surface of the insulating cylinder is uniform. Embodiment
[0030] On the basis of Embodiment 2, a drying component is provided inside the bellows 13. The drying component includes: a partition 3 is fixedly connected between the inner walls of the bellows 13. The partition 3 divides the bellows 13 into two upper cavities 31 and a lower cavity 32. A hot air blower 33 is fixedly installed inside the upper cavity 31. Two air ducts 34 are respectively and fixedly installed on the inner walls of the opposite sides of the box body 1. The output end of the hot air blower 33 communicates with the inside of the lower cavity 32. A plurality of air inlets 35 are provided on one side of the upper cavity 31. Air supply pipes 36 are respectively connected to the opposite sides of the lower cavity 32. The two air ducts 34 are symmetrically arranged. The two air supply pipes 36 are respectively connected to the two air ducts 34.
[0031] After spraying is completed, close the paint spraying head 25, and then start the hot air blower 33 through the control panel on one side of the box body 1. After the hot air blower 33 starts, hot air is generated. The hot air enters the lower cavity 32. The hot air is conveyed to the two air ducts 34 through the air supply pipes 36 on both sides. The hot air is ejected from the two air ducts 34. The two air ducts 34 send air towards the center. The air sent out is relatively gentle, enabling the surface paint to dry quickly. Moreover, the hot air flow will flow inside the box body 1, cooperating with the slowly rotating insulating cylinder, making the drying efficiency higher. Embodiment
[0032] On the basis of Embodiment 2, a conveyor belt 4 is provided inside the box body 1. One end of the conveyor belt 4 extends outside the box body 1. A box door 41 is rotatably connected to the inner wall of one side of the box body 1 through a hinge. A fixing table 5 is fixedly connected to the top of the conveyor belt 4. A rotating table 51 is rotatably connected to the fixing table 5. A speed reducer 52 is fixedly installed inside the fixing table 5. The top end of the driving shaft of the speed reducer 52 is fixedly connected to a driving gear 53. A rotating rod 54 is fixedly connected to the bottom of the rotating table 51. The bottom end of the rotating rod 54 penetrates through the fixing table 5 and extends to the inside. A driven gear 55 is fixedly connected to the bottom end of the rotating rod 54. The driven gear 55 is meshed with the driving gear 53.
[0033] When spraying the insulating cylinder, open the box body 1, then start the conveyor belt 4 through the control panel, control the conveyor belt 4 to move outwards, drive the fixing table 5 to move out of the box body 1, then place the insulating cylinder on the rotating table 51, then control the conveyor belt 4 to move the fixing table 5 into the box body 1, and then close the box door 1 for spraying processing. During processing, start the speed reducer 52 through the control panel. After the speed reducer 52 starts, it drives the driving gear 53 to rotate. The driving gear 53 rotates and meshes with the driven gear 55, thereby driving the driven gear 55 to rotate. The driven gear 55 drives the rotating table 51 to rotate through the rotating rod 54. Since the small gear drives the large gear to rotate, the rotation speed of the rotating table 51 is relatively slow, which is beneficial for spraying and drying.
