Description

Technical Field

[0001] This utility model relates to the field of coating apparatus technology, and more specifically, to a coating apparatus for sharpening painted surfaces of articles. Background Technology

[0002] A coating device for sharpening painted surfaces typically refers to a device used to refine the surface of an object, especially during the paint coating process, to make the coating more uniform, smooth, and durable. This device is generally used in the application of paints, spray paints, or other coating materials to enhance the quality and appearance of the painted surface by "sharpening" or "finishing" it.

[0003] Existing coating devices typically have nozzles with lifting and horizontal movement structures to facilitate uniform spraying of paint onto the surface of an object. However, when spraying the curved surface of a cylindrical object, an additional clamping and rotating mechanism is usually required to clamp and rotate the cylindrical object. When clamping and rotating mechanisms are set on the outside of the object, they can easily obstruct the surface of the object, creating blind spots in the spraying process and affecting the coating effect. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a coating device for sharpening the paint surface of articles, which has the advantage of improving the applicability of the coating device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating device for sharpening paint surfaces, comprising a worktable, a rotating assembly mounted at the center of the top of the worktable, the rotating assembly including a positioning frame fixedly connected to the top of the worktable, a rotating ring mounted on the inner side of the positioning frame, a positioning groove formed on the outer surface of the rotating ring, and annular toothed blocks arranged around the bottom of the rotating ring. A rotary motor is fixedly connected to the right side of the bottom of the worktable, a drive gear is fixedly connected to the output shaft of the rotary motor, the drive gear meshing with the annular toothed blocks, a lifting assembly mounted on the right side of the top of the rotating ring, a moving assembly mounted on the left side of the lifting assembly, a distance adjustment assembly mounted on the left side of the moving assembly, and a spray nozzle mounted on the left side of the distance adjustment assembly.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] like Figures 1 to 7As shown, this utility model provides a coating device for sharpening paint surfaces, including a worktable 1. A rotating component 2 is installed in the middle of the top of the worktable 1. The rotating component 2 includes a positioning frame 201 fixedly connected to the top of the worktable 1. A rotating ring 202 is installed on the inner side of the positioning frame 201. A positioning groove 203 is opened on the outer surface of the rotating ring 202. Annular toothed blocks 204 are arranged around the bottom of the rotating ring 202. A rotary motor 701 is fixedly connected to the right side of the bottom of the worktable 1. A drive gear 702 is fixedly connected to the output shaft of the rotary motor 701. The drive gear 702 meshes with the annular toothed blocks 204. A lifting component 3 is installed on the right side of the top of the rotating ring 202. A moving component 4 is installed on the left side of the lifting component 3. A distance adjustment component 5 is installed on the left side of the moving component 4. A spray nozzle 6 is installed on the left side of the distance adjustment component 5.

[0025] In this embodiment, when spraying the surface of an item, the item is placed at the top center of the workbench 1. When the surface to be sprayed is a planar structure, the moving motor 402 is started to drive the translation screw 403 to rotate. Under the threaded thrust of the translation screw 403, the moving block 404 moves back and forth along the outer side of the translation screw 403, thereby driving the spray nozzle 6 to spray the surface of the item in the back and forth direction. Then, the lifting motor 305 drives the driving bevel gear 306 to rotate. Through gear meshing, the driven bevel gear 304 drives the lifting screw 302 to rotate. Under the threaded thrust of the lifting screw 302, the lifting block 303 moves down a certain distance along the lifting screw 302, thereby causing the spray nozzle 6 to spray the next height position in the back and forth direction, thereby achieving the spraying of the entire surface of the item.

[0026] When the surface of the object is a cylindrical curved surface, the rotary motor 701 is started to drive the drive gear 702 to rotate. Through the meshing of the drive gear 702 and the ring tooth block 204, the rotating ring 202 is driven to rotate. Then the spray nozzle 6 can spray the surface area around the curved surface of the object evenly. After one round of spraying is completed, the lifting component 3 drives the spray nozzle 6 to move down a certain distance, so that the spray nozzle 6 can spray the curved surface around the next height.

[0027] The lifting assembly 3 includes a fixed frame 301 fixedly connected to the top of the rotating ring 202. A lifting screw 302 is movably sleeved on the inner side of the fixed frame 301. A lifting block 303 is threadedly sleeved on the outer side of the lifting screw 302. A driven bevel gear 304 is fixedly connected to the bottom of the outer side of the lifting screw 302. A lifting motor 305 is fixedly connected to the bottom of the front side of the fixed frame 301. A driving bevel gear 306 is fixedly connected to the output shaft of the lifting motor 305. The driving bevel gear 306 and the driven bevel gear 304 mesh with each other. Rollers 331 are movably sleeved on both the front and back sides of the lifting block 303. The rollers 331 are in contact with the inner wall of the fixed frame 301.

[0028] The lifting motor 305 drives the active bevel gear 306 to rotate. Through gear meshing, the driven bevel gear 304 drives the lifting screw 302 to rotate. Under the thread thrust of the lifting screw 302, the lifting block 303 moves downward along the lifting screw 302, thereby enabling the spray nozzle 6 to spray the object at different heights. When the lifting block 303 moves, the roller 331 rolls and rubs against the inner wall of the fixed frame 301, preventing the lifting block 303 from getting stuck and making the movement smoother.

[0029] The movable component 4 includes a fixed frame 401 fixedly connected to the left side of the lifting block 303. A movable motor 402 is fixedly connected to the front of the fixed frame 401. A translation screw 403 is fixedly connected to the output shaft of the movable motor 402. A movable block 404 is threaded onto the outer side of the translation screw 403.

[0030] The moving motor 402 is started to drive the translation screw 403 to rotate. Under the thread thrust of the translation screw 403, the moving block 404 moves back and forth along the outside of the translation screw 403, thereby enabling the spray nozzle 6 to spray evenly on the flat surface of the object.

[0031] The distance adjustment assembly 5 includes a threaded rod 503 movably connected to the left side of the moving block 404. A threaded tube 504 is threadedly sleeved on the outer side of the threaded rod 503. A mounting plate 505 is fixedly connected to the left side of the threaded tube 504. A driven cylindrical gear 506 is fixedly sleeved on the right side of the outer side of the threaded rod 503. The distance adjustment assembly 5 also includes an adjustment motor 501 fixedly connected to the top of the moving block 404. The output of the adjustment motor 501 is fixedly connected to a driving cylindrical gear 502. The driving cylindrical gear 502 and the driven cylindrical gear 506 mesh with each other.

[0032] The start-up adjustment motor 501 drives the driving cylindrical gear 502 to rotate. Through the meshing action with the driven cylindrical gear 506, it drives the threaded rod 503 to rotate. Under the thread thrust of the threaded rod 503, the threaded tube 504 drives the mounting plate 505 to move away from or closer to the moving block 404, thereby adjusting the distance between the spray nozzle 6 and the surface of the object.

[0033] Working principle and usage process of this utility model:

[0034] When spraying the surface of an item, the item is placed at the top center of the workbench 1. When the surface to be sprayed is a flat structure, the moving motor 402 is started to drive the translation screw 403 to rotate. Under the threaded thrust of the translation screw 403, the moving block 404 moves back and forth along the outside of the translation screw 403, thereby driving the spray nozzle 6 to spray the surface of the item in the back and forth direction. Then, the lifting motor 305 drives the driving bevel gear 306 to rotate. Through the meshing of the gears, the driven bevel gear 304 drives the lifting screw 302 to rotate. Under the threaded thrust of the lifting screw 302, the lifting block 303 moves down a certain distance along the lifting screw 302, thereby causing the spray nozzle 6 to spray the next height position in the back and forth direction, thus achieving the spraying of the entire surface of the item.

[0035] When the surface of the object is a cylindrical curved surface, the rotary motor 701 is started to drive the drive gear 702 to rotate. Through the meshing of the drive gear 702 and the ring tooth block 204, the rotating ring 202 is driven to rotate. Then the spray nozzle 6 can spray the surface area around the curved surface of the object evenly. After one round of spraying is completed, the lifting component 3 drives the spray nozzle 6 to move down a certain distance, so that the spray nozzle 6 can spray the curved surface around the next height.
