[0015] Beneficial effects

[0016] This utility model provides a spraying device for dry-type transformer production. Compared with the prior art, it has the following advantages:

[0017] (1) The spraying device for dry-type transformer production controls the spraying distance of the spraying components through the adjustment mechanism. The first motor drives the active tooth plate and the driven tooth plate to rotate. The moving column embedded in the arc groove moves linearly along the moving groove under the action of the groove wall, moving closer to or away from the fixed column. The moving column drives the adjustment plate to slide along the receiving groove. The active tooth plate rotates clockwise, and the moving column moves away from the fixed column along the arc groove. The adjustment plate extends outward. At this time, the spraying components are close to the workpiece. If it rotates counterclockwise, the spraying components move away from the workpiece. The five sets of adjustment plates extend and retract synchronously to ensure that the distance between each spray gun and the workpiece surface is consistent.

[0018] (2) The spraying device for dry-type transformer production starts the liquid pump through the spraying component, draws paint from the storage tank through the feed pipe, and delivers it to the distribution box through the discharge pipe. The distribution box distributes the paint to 5 independent distribution chambers. The paint flows unidirectionally to the distribution pipe through the one-way valve to ensure that the supply pressure of each distribution pipe is consistent. The paint is delivered to the spraying head through the distribution pipe and sprayed out from the nozzle under high pressure to form uniform atomized particles. The workpiece is moved and rotated by the fixed mechanism and the moving component to spray the workpiece in all directions. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1 A spraying device for dry-type transformer production, comprising:

[0027] Mounting frame 1, with a sliding groove 6 at the top and a movable component 4 mounted on the upper end of the sliding groove 6;

[0028] Fixing mechanism 5 is located at the upper end of mounting frame 1. Fixing mechanism 5, together with moving component 4, can facilitate the overall spraying of workpiece.

[0029] Spraying component 3 is located on one side wall of mounting frame 1;

[0030] Adjustment mechanism 2 is located inside one side wall of mounting frame 1. Adjustment mechanism 2 works in conjunction with spraying component 3. Adjustment mechanism 2 drives spraying component 3 to move and adjust the distance between it and the surface of the workpiece to be sprayed.

[0031] In this embodiment, the fixing mechanism 5 can fix the workpiece to be sprayed. The moving component 4 is activated to drive the workpiece clamped by the fixing mechanism 5 to move in the slide 6. The adjusting mechanism 2 adjusts the position of the spraying component 3 according to the size of the workpiece, and then the spraying work is carried out through the spraying component 3.

[0032] Example 2:

[0033] Please see Figure 1 and Figure 4 This embodiment provides a technical solution based on embodiment one: the adjustment mechanism 2 includes a mounting plate 21. One side of the mounting plate 21 is fixedly installed on the inner wall of one side of the mounting frame 1. A fixing column 28 is fixedly installed at the middle position of the other side of the mounting plate 21. A bearing is fixedly sleeved on the outer surface of the fixing column 28. A driven toothed plate 23 is fixedly installed on the outer ring surface of the bearing. A driving toothed plate 26 is meshed and connected on one side of the driven toothed plate 23. A fixing plate is fixedly installed on the outer wall of one side of the mounting frame 1. A first motor 27 is fixedly installed at the upper end of the fixing plate. A bearing is sleeved on the output end of the first motor 27 and passes through the mounting frame 1 and the mounting plate 21 and is fixedly connected to one side wall of the driving toothed plate 26.

[0034] The mounting plate 21 has five equidistant slots 7. Each slot 7 has a through-hole groove 8 on the side near the active toothed plate 26. An adjusting plate 22 is slidably installed in each slot 7. A moving column 24 is fixedly installed on one side of each adjusting plate 22 near the fixed column 28. The end of the adjusting plate 22 away from the fixed column 28 passes through the slot 7 and is fixedly installed with a connecting arc plate 29. The surface of the active toothed plate 26 has five arc grooves 10 that are equidistantly opened. The other end of each moving column 24 passes through the arc groove 10 and is fixedly installed with a limit block 25.

[0035] In this embodiment, the adjustment mechanism 2 controls the spraying distance of the spraying assembly 3. The first motor 27 drives the active toothed plate 26 to rotate, and the driven toothed plate 23 meshing on one side rotates. When the active toothed plate 26 rotates, the arc-shaped groove 10 moves in a circle around the fixed column 28. The moving column 24 embedded in the arc-shaped groove 10 moves linearly along the moving groove 8 under the thrust of the groove wall, moving closer to or away from the fixed column 28. The moving column 24 drives the adjustment plate 22 to slide along the receiving groove 7. The active toothed plate 26 rotates clockwise, and the moving column 24 moves away from the fixed column 28 along the arc-shaped groove 10. The adjustment plate 22 extends outward. At this time, the spraying assembly 3 is close to the workpiece. If it rotates counterclockwise, the moving column 24 moves towards the fixed column 28, the adjustment plate 22 retracts, and the spraying assembly 3 moves away from the workpiece. The five sets of adjustment plates 22 extend and retract synchronously to ensure that the distance between each spray gun and the workpiece surface is consistent.

[0036] Please see Figure 3 The spraying assembly 3 includes a material storage tank 31. One side of the material storage tank 31 is fixedly installed on the bottom of the outer wall of the mounting frame 1. A liquid pump 33 is fixedly installed on the top of the material storage tank 31. The inlet end of the liquid pump 33 is sealed and connected to a feed pipe 32. The other end of the feed pipe 32 is sealed and connected to the material storage tank 31. The outlet end of the liquid pump 33 is sealed and connected to a discharge pipe 34. The other end of the discharge pipe 34 is sealed and connected to a distribution box 35. One side of the distribution box 35 is fixedly installed on the outer wall of the mounting frame 1. Five distribution pipes 36 are equidistantly sealed and connected to the surface of the distribution box 35. The other ends of the five distribution pipes 36 are all connected through the arc plate 29 and sealed and connected to a spray head 37.

[0037] In this embodiment, the liquid pump 33 is started, and paint is drawn from the storage tank 31 through the feed pipe 32 and delivered to the distribution box 35 through the discharge pipe 34. The distribution box 35 distributes the paint into 5 independent distribution chambers. The paint flows unidirectionally to the distribution pipe 36 through the one-way valve to ensure that the supply pressure of each distribution pipe 36 is consistent. The paint is delivered to the spray head 37 through the distribution pipe 36 and sprayed out from the nozzle under high pressure to form uniform atomized particles. The workpiece is moved and rotated by the fixing mechanism 5 and the moving component 4 to spray the workpiece in all directions.

[0038] Please see Figure 2The moving component 4 includes a moving plate 41, a slider 42 is fixedly installed at the bottom of the moving plate 41, the slider 42 is slidably installed in the slide groove 6, and a cylinder 43 is fixedly installed on the inner wall of the mounting frame 1 away from the adjustment mechanism 2, and the output end of the cylinder 43 is fixedly connected to the moving plate 41.

[0039] In this embodiment, the movable component 4 controls the position of the fixed workpiece. When fixing the workpiece, the cylinder 43 retracts and drives the movable plate 41 to stop at the position of the mounting frame 1 away from the spraying component 3. After the operator clamps the dry transformer workpiece through the fixing mechanism 5, the cylinder 43 extends and moves the workpiece towards the position of the spraying component 3. During the movement, the slider 42 slides along the slide groove 6, and the slide groove 6 restricts the movement position of the movable plate 41.

[0040] Please see Figure 2 The fixing mechanism 5 includes a second motor 51. One end of the second motor 51 is fixedly installed on one side wall of the moving plate 41. The output end of the second motor 51 is fixedly connected to a rotating plate 52. The surface of the rotating plate 52 is symmetrically provided with mounting grooves 9. A threaded rod 55 is provided in the mounting groove 9. A threaded sleeve 56 is threadedly connected to one end of the threaded rod 55 near the moving plate 41. A supporting arc plate 57 is fixedly installed at the other end of the threaded rod 55. Several sets of springs 58 are provided on the side of the two supporting arc plates 57 away from each other. One end of the spring 58 is fixedly connected to the supporting arc plate 57. An arc-shaped top plate 53 is fixedly connected to the other end of the spring 58. A stop block 54 is fixedly connected to the end of the arc-shaped top plate 53 away from the second motor 51.

[0041] In this embodiment, the fixing mechanism 5 can fix workpieces of different sizes. According to the inner diameter of the circular workpiece of the dry transformer, the screw sleeve 56 is rotated to loosen it slightly, and then the threaded rods 55 on both sides are moved to drive the inner side of the supporting arc plate 57 to move, so that the initial distance between the arc-shaped top plates 53 on both sides is slightly smaller than the diameter of the workpiece. The workpiece is put on the arc-shaped top plates 53 on both sides, and the two sets of screws are pulled outward. The screw sleeve 56 is tightened so that the arc-shaped top plate 53 is close to the surface of the workpiece. The spring 58 is compressed. The stop block 54 fixedly connected to the end of the arc-shaped top plate 53 away from the second motor 51 can block the workpiece during rotation to prevent the workpiece from falling off. After the moving component 4 transports the workpiece to the spraying area, the second motor 51 is started, driving the rotating plate 52 and the clamped workpiece to rotate. During the rotation of the workpiece, the atomized coating of the spraying component 3 can evenly cover the cylindrical surface. With the linear conveying of the moving component 4, it is suitable for long cylindrical workpieces.
