[0001] This utility model relates to the field of spraying technology, and in particular to an automated anti-corrosion spray gun with adjustable spraying angle. Background Technology

[0002] Anti-corrosion spraying involves coating metal or non-metal surfaces with anti-corrosion materials to form a protective layer that isolates them from air, moisture, and corrosive media, thereby extending the material's service life. Its benefits include: significantly reducing corrosion risk and lowering maintenance and replacement costs; improving material weather resistance and adapting to harsh environments; enhancing structural stability and ensuring safety performance; and simultaneously improving aesthetics. Widely used in construction, bridges, ships, pipelines, and other fields, it is an economical and efficient anti-corrosion method that effectively saves resources and improves engineering durability. Existing spray guns generally suffer from the following defects: fixed or limited angle adjustment requires frequent manual intervention, resulting in low spraying efficiency and uneven coverage of complex curved surfaces, easily leading to missed coatings or paint build-up; horizontal rotation and pitch adjustment functions are separated or missing, making it difficult to achieve automated multi-degree-of-freedom coordinated movement; waste liquid recovery systems are rudimentary or absent, with residual paint being directly discharged, causing pollution and waste of raw materials; and there is a lack of effective filtration design, making it impossible to recycle preservatives, resulting in high long-term operating costs. Utility Model Content

[0003] The purpose of this invention is to provide an automated anti-corrosion spray gun with adjustable spraying angle, which solves the problem that the fixed or limited angle adjustment of the spray gun in the prior art requires frequent manual intervention, resulting in low spraying efficiency and uneven coverage of complex curved surfaces.

[0004] To achieve the above objectives, an automated anti-corrosion spray gun with adjustable spraying angle is provided, including a collection box, a bracket fixedly connected to the top of the collection box, a fixing ring fixedly connected to the top of the bracket, a limiting groove opened inside the fixing ring, a limiting ring fitted inside the limiting groove, and a rotating ring fixedly connected to the inner end of the limiting ring. The outer end of the limiting ring is fixedly connected to a gear 1, the outer end of the fixed ring is fixedly connected to a drive box 2, the bottom of the drive box 2 is fixedly connected to a motor 1, the output end of the motor 1 passes through the drive box 2 and is fixedly connected to a gear 2, and the gear 2 is partially inserted into the inside of the limiting groove. The gear 1 and gear 2 mesh with each other.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] Reference Figure 1-4 This utility model discloses an automated anti-corrosion spray gun with adjustable spraying angle, including a collection box 1, a bracket 4 fixedly connected to the top of the collection box 1, a fixing ring 7 fixedly connected to the top of the bracket 4, a limiting groove opened inside the fixing ring 7, a limiting ring 17 fitted inside the limiting groove, and a rotating ring 8 fixedly connected to the inner end of the limiting ring 17. The bracket 4 can stably support the entire spraying assembly. The outer end of this device is provided with a spray box shell. This patent does not show the internal structure in order to demonstrate that the entire shell can wrap the spraying assembly. The top opening can facilitate the connection of the delivery pipe 11 and improve its protective effect. Secondly, the mutual cooperation between the limiting ring 17 and the limiting groove can make the rotating ring 8 rotate stably inside the fixing ring 7 to complete automated rotary spraying. The connection between the delivery pipe 11 and the nozzle 10 is a high-pressure rotary joint with an integrated bidirectional mechanical seal (SiC ceramic ring) that can withstand pressure ≥1MPa and is suitable for corrosive media. Gear 14 is fixedly connected to the outer end of the limiting ring 17, and drive box 13 is fixedly connected to the outer end of the fixing ring 7. Motor 16 is fixedly connected to the bottom of drive box 13. Gear 15 is fixedly connected to the output end of motor 16 through drive box 13. Gear 14 and gear 15 are partially installed inside the limiting groove. Gear 14 and gear 15 mesh with each other. When motor 16 is started, it drives gear 15 to rotate. Under the action of meshing, gear 14 and the inner rotating ring 8 can be rotated. Through the connection of rotating ring 8, it can be ensured that the internal spray gun can rotate 360 ​​degrees and spray the surface of the workpiece evenly. A rotating frame 9 is fixedly connected to the inner end of the rotating ring 8. A rotating shaft 20 is rotatably connected inside the rotating frame 9. A nozzle 10 is fixedly connected to the middle of the rotating shaft 20. A delivery pipe 11 is rotatably mounted on the top of the nozzle 10. A drive box 12 is fixedly connected to the outer end of the rotating frame 9. A gear 4 19 is fixedly connected to one end of the rotating shaft 20 through the drive box 12. A motor 21 is fixedly connected to the right inner side of the drive box 12. A gear 3 18 is fixedly connected to the output end of the motor 21. Gear 3 18 and gear 4 19 mesh with each other. When the motor 21 is started, it drives gear 3 18 to rotate. Under the meshing action, it drives gear 4 19 and the rotating shaft. The 20-degree rotation enables automatic pitch adjustment of the nozzle, increasing the spraying area and automating angle adjustment, thus greatly improving the overall spraying efficiency of the device. A dynamic sealing sleeve is added to the motor mounting port of drive box 2 (13) / drive box 1 (12), using fluororubber seals to encase the motor output shaft, raising the protection level to IP65. Furthermore, the piston rod of cylinder 5 is dynamically sealed and reinforced with a corrugated protective sleeve (material: PTFE + glass fiber composite layer), one end fixed to the cylinder end cap, and the other end sealed to the bottom of the support platform 6, covering the piston rod throughout its stroke and isolating it from paint contact. Temperature range: -40℃ to 260℃.

[0016] A cylinder 5 is fixedly connected to the inner center of the collection box 1. A support platform 6 is fixedly connected to the extended end of the cylinder 5. By setting the cylinder 5, the height of the support platform 6 and the workpiece can be adjusted, thereby ensuring that the spraying mechanism can spray the surface of the workpiece evenly. A drain pipe 22 is installed through the lower left side of the collection box 1. A filter box 2 is installed through the other end of the drain pipe 22. Two sets of filter screens 23 are installed inside the filter box 2. A drain pipe 3 is installed through the side of the filter box 2 opposite to the collection box 1. By setting the filter box 2, the waste liquid after spraying can be filtered. The filtered anti-corrosion liquid can be collected for subsequent recycling, reducing production costs and improving the applicability of the device. An inspection door is set at the rear end of the filter box 2, which allows for regular disassembly and cleaning of the two filter screens to avoid damage and clogging. Both motors in this device are equipped with spring-loaded electromagnetic brakes at their rear ends. When energized, the electromagnetic coil generates magnetic force to overcome the spring pressure and release the brake pad, allowing the motor shaft to rotate freely. When de-energized, the spring force presses the brake pad against the friction disc, locking the motor shaft through friction and preventing it from rotating, thus achieving a self-locking effect.

[0017] Working principle: During use, the operator places the workpiece to be sprayed on the support platform 6, then connects the delivery pipe 11 to the liquid storage device, starts the pump to send the anti-corrosion liquid into the nozzle 10 and sprays it outward to protect the surface of the workpiece. During the spraying process, the motor 16 drives the gear 2 15 to rotate. Under the meshing action, the gear 14 and the inner rotating ring 8 can rotate. Through the connection of the rotating ring 8, it can ensure that the internal spray gun can rotate 360 ​​degrees to evenly spray the surface of the workpiece and improve its spraying effect. Next, the motor 21 drives the gear 3 18 to rotate. Under the meshing action, the gear 4 19 and the rotating shaft 20 can rotate to realize the automatic pitch adjustment of the nozzle, which can increase the spraying area and complete the automated angle adjustment, greatly improving the spraying efficiency of the entire device.

[0018] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
