Technical Field

[0001] The utility model relates to the field of navigation mark production, in particular to a paint spraying device for an arc surface outer wall. Background Art

[0002] Navigation marks, also known as aids to navigation, are visual, audio and radio aids to navigation set up to help ships navigate safely, economically and conveniently; their main functions include indicating waterways, positioning ships, marking danger zones and marking special waters.

[0003] The production and processing flow of navigation marks is a complex and delicate process, which mainly includes: material preparation, processing and manufacturing, assembly and debugging, spraying, quality inspection, packaging and transportation; spraying is one of the important steps in the processing of navigation marks, and the eye-catching paint color can improve its visibility at night.

[0004] The existing navigation mark is usually sprayed directly on its surface. During production and observation, it is found that the outer wall of the navigation mark is mostly curved, and dead angles are easily generated during spraying, which makes it difficult to spray the surface of the navigation mark evenly.

[0005] Therefore, in order to solve the above problems, a paint spraying device for curved outer wall is proposed. Utility Model Content

[0008] Preferably, a plurality of second magnets are fixed to the middle of the connecting frame; a plurality of first magnets are fixed to the inner side wall of the slide groove; the first magnet and the second magnet are arranged correspondingly; when the elastic spring resets the connecting frame, the connecting frame will be affected by the magnetic force of the first magnet and the second magnet, which slows down the movement speed of the connecting frame and the spray ring, increases the time for the spray ring to spray the navigation mark, and enhances the uniformity of the spray ring spraying the curved surface of the navigation mark.

[0016] 2. In the arc surface outer wall paint spraying device described in the utility model, the connecting frame will be affected by the magnetic force of the first magnet and the second magnet when the elastic spring is reset, which slows down the movement speed of the connecting frame and the spray ring, increases the time for the spray ring to spray the navigation mark, and enhances the uniformity of the spray ring spraying the arc surface of the navigation mark.

[0025] Specific examples are given below.

After the motor 12 is started, The rotating shaft 15 will rotate with the support plate 16, and the rotation of the support plate 16 will cause the navigation mark to rotate, so that the spray ring 110 can spray the surface of the navigation mark. At the same time, the rotating shaft 15 will also cause the fixed plate 13 to connect with the convex plate 14 to rotate. When the convex plate 14 rotates, it will contact and squeeze the connecting plate 18. After the connecting plate 18 is squeezed by the convex plate 14, the connecting frame 17 will slide along the fixed frame 1. Because the convex plate 14 is an arc-shaped structure, the connecting plate 18 will carry the connecting frame 17 to do reciprocating motion. When the connecting frame 17 moves, the elastic The force spring 19 is in a deformed state, and the connecting frame 17 will move with the spray ring 110 when it slides. The spray ring 110 will move repeatedly along the surface of the navigation mark and evenly spray the curved surface of the navigation mark until the surface of the navigation mark is sprayed. The connecting frame 17 will carry the spray ring 110 to reciprocate along the fixed frame 1 under the extrusion of the convex plate 14 and the connecting plate 18, so that the spray ring 110 can spray different heights of the navigation mark surface, enhance the uniformity of the spray ring 110 spraying the navigation mark, and reduce the dead angle that appears when the spray ring 110 sprays the navigation mark.

The damping springs 34 will also be compressed under the squeezing action of the fixing rods 33. When the damping springs 34 are compressed, they will absorb the impact generated when the buoy and the top plate 3 contact each other, thereby playing a buffering role when the buoy is hoisted, and reducing the damage to the support plate 16 caused by the collision between the buoy and the support plate 16 during hoisting.

When the connecting frame 17 slides, it will move with the spray ring 110, and the spray ring 110 will move repeatedly along the surface of the navigation mark and evenly spray the curved surface of the navigation mark until the surface of the navigation mark is sprayed.
