[0024] The conveying mechanism 1 includes a guide rail 2 and a placement plate 3. Two parallel guide rails 2 are fixed on the ground by bolts, and a placement plate 3 is placed on the guide rails 2. A guide groove 4 is provided at the bottom of the placement plate 3 and is clamped on the guide rail 2. In this way, the placement plate 3 moves along the guide rail 2.

[0025] The surrounding spraying mechanism 11 includes a lifting plate 12, a sliding assembly 13 and a spraying assembly 24. A rectangular through hole 7 is opened on the conveying mechanism 1 for the lifting plate 12 to pass through. The lifting plate 12 is divided into two groups, an upper and a lower group. Telescopic assemblies 27 are installed on the upper and lower groups of lifting plates 12. A rectangular frame is installed on the ground. When the placement plate 3 is transported on the guide rail, the placement plate 3 and the iron core pass through the rectangular frame. The telescopic assembly 27 is installed on the rectangular frame by bolts. The telescopic assembly 27 is a cylinder. The lifting and lowering of the lifting plate 12 is achieved by the telescopic assembly 27. The lifting and lowering of the lifting plate 12 is achieved by the telescopic assembly 27. The two ends of each lifting plate 12 are equipped with vertically arranged sliding assemblies 13. The sliding assembly 13 slides with the end of the lifting plate 12, and a spraying assembly 24 is installed on the sliding assembly 13. The spraying assembly 24 moves on the sliding assembly 13, so that spraying is achieved on both sides of the transformer core. When working, the placement plate 3 is moved to the surrounding spraying mechanisms 11, and the rectangular through holes 7 on the placement plate 3 are provided for the lifting plate 12 to pass through, so that the telescopic assembly 27 is lifted, and the upper and lower sets of sliding assemblies 13 are brought close to each other. The spraying assembly 24 is located in the middle section of the core, and the spraying assembly 24 moves on the sliding assembly 13. The spraying assembly 24 located above rises and the spraying assembly 24 located below falls, so that the outer walls of both sides of the core are sprayed.

[0026] The spray assembly 24 includes a first mounting rod 25 and a first spray head 26, wherein a plurality of first spray heads 26 are mounted on the first mounting rod 25 by means of bolt fastening, and the plurality of first spray heads 26 are connected to the pump body through a pipe, and the other end of the pump is connected to the paint bucket through a pipe, and the paint is pumped to the first spray head 26 by the pump, and the paint is sprayed onto the surface of the iron core; the sliding assembly 13 includes a sliding seat 14 and a slide rail 15, wherein the sliding seat 14 is clamped on the slide rail 15 and the sliding seat 14 is on the slide rail 15 Translation, a long slot 16 is opened on the slide rail 15, a rotating shaft 17 is installed on the lifting plate 12 through a bearing, one end of the rotating shaft 17 is fixed to the output shaft of the stepper motor by welding, and the rotating shaft is driven by the stepper motor to rotate, and the rotating shaft 17 extends into the slot 16. A baffle 18 is installed at the end of the lifting plate 12 by welding against the bottom of the slide rail 15. Under the action of the baffle 18 and the rotating shaft 7, the slide rail 15 is vertically lifted and lowered along the rotating shaft 7. A sprocket 19 is installed by welding, and a chain 50 meshing with the sprocket 19 is installed on the top of the slide rail 15 by welding. The chain 50 is divided into two sections, a straight line and an arc, and the arc is at a 90° angle. When the sprocket 19 moves the arc section of the chain 50, the sprocket 19 drives the slide rail 15 to rotate 90° and the slide rail 15 is parallel to the lifting plate 12. A bidirectional screw 20 driven by a motor is installed on the lifting plate 12 through a bearing. A threaded sleeve 21 is sleeved on each thread of the bidirectional screw 20. When the bidirectional screw rod 20 rotates, the threaded sleeve 21 moves left and right. The bottom of the threaded sleeve 21 slides with the lifting plate 12. A push plate 22 is fixedly mounted on the threaded sleeve 21 by welding, which rests on the sliding seat 14. The push plate 22 pushes the sliding seat 14 to move. A return spring 23 is fixed between the sliding seat 14 and the slide rail 15 by welding. The spring pulls the sliding seat 14 toward the end of the slide rail 15 (that is, the end of the slide rail with the arc chain).When working, the spraying assembly 24 is required to spray the top and bottom of the iron core. When spraying the side, the stepper motor is rotated, so that the sprocket 19 rotates. Since the slide rail 15 is equipped with a chain 50 that meshes with the sprocket 19, when the sprocket 19 rotates, the slide rail 15 slides along the rotating shaft 17, so that the spraying assembly 24 moves from the middle to the upper and lower sides, thus realizing the side spraying of the iron core. When the slide rail 15 moves upward to mesh with the arc end of the sprocket 19 and the chain 50, the slide rail 15 swings parallel to the lifting plate 12. Since the sprocket 19 and the chain 50 are in meshing state, the slide rail 15 maintains a horizontal state, and the spraying assembly 24 faces the top and bottom surfaces of the iron core. When the spraying assembly 24 needs to be translated, the motor drives the bidirectional screw rod 20 to rotate, so that the threaded sleeve 21 moves from the bidirectional screw rod The two ends of the rod 20 move toward the middle, and the bottom of the threaded sleeve 21 is a plane that fits the lifting plate 12. In this way, when the bidirectional screw rod rotates, the threaded sleeve 21 will not rotate with the bidirectional screw rod 20. The threaded sleeve 21 moves left and right along the lifting plate 12, and the threaded sleeve 21 drives the push plate 22 to move left and right. The push plate 22 pushes the sliding seat 14 to move inward, thus completing the spraying of the top and bottom surfaces of the iron core. When the spraying is completed, the bidirectional screw rod 20 rotates in the opposite direction, so that the threaded sleeve 21 returns to the left and right sides of the lifting plate 12, and the sliding seat 14 returns under the action of the spring. The telescopic component 27 returns to make way for the movement of the iron core. When it is necessary to spray the two sides of the next iron core, the rotating shaft rotates in the opposite direction, swinging the slide rail into a vertical shape and moving the middle (that is, the upper slide rail descends and the lower slide rail rises), thus completing the spraying around the iron core.

[0027] The inner spraying mechanism 28 includes a rotating rod 30, a swing rod 31, a spliced track 32 and a slider 33.

At the same time, the spliced track 32 rotates 90 degrees to become vertical, and then the slider 33 continues to translate to spray the left and right inner sides of the hollow position of the iron core. After completion, the rotating rod 30 returns to its position, the swing assembly 29 is lifted, and the placement plate 3 is conveyed to give way.
