[0044] The working process of a rotary adjustable spray device:

[0045] The working process of the rotary adjustable spray device is as follows: First, the steel structure enters the device through the feeding unit 1. The active roller 12 on the support 11 rotates under the drive of the drive motor 13, causing the steel structure to move linearly towards the rotary spray assembly 2. At the same time, the discharge unit 3, with the same structure and opposing arrangement as the feeding unit 1, is ready to receive the sprayed steel structure. When the steel structure enters the area of ​​the rotary spray assembly 2, the protective shell 4, which is hinged to the rotary spray assembly 2 on both sides, plays its role. One end with a groove 41 wraps around the steel structure to prevent the sprayed liquid from splashing. The protective shell 4 is located above the feeding unit 1 and the discharge unit 3 to ensure that the protection range covers the entire conveying process of the steel structure. The power and liquid supply for the spraying operation come from the storage unit 5. The liquid in the storage tank 51 is pressurized by the pressure pump 52 and then transported through the extension pipe 53 to the collection chamber 221 of the spraying unit 22 in the rotary spraying assembly 2. The liquid flows from the first outlet 2211 of the collection chamber 221 into the inlet pipe 2231 connected by the connecting pipe 222, and then into the rotating disk 223. Finally, it is transported to the nozzle 224 through the outlet pipe 2237 arranged circumferentially at the lower end of the rotating disk 223 to achieve spraying. During the spraying process, the first adjustment unit 23 can adjust the rotation state of the rotating disk 223. The servo motor 232 on the first connecting frame 231 drives the drive gear 233 to rotate. Through meshing with the driven gear 2236, it drives the liquid inlet pipe 2231 to rotate. The bearing 2232 and fixing screw 2233 around the liquid inlet pipe 2231 ensure rotational stability and sealing, thereby driving the rotating disk 223 and the nozzle 224 to rotate. At the same time, the second adjustment unit 24 can adjust the spray angle of the nozzle 224. Turning the handwheel 247 drives the screw 245 to rotate, causing the threaded bushing 246 to move axially along the threaded rod 245. The second connecting frame 244 pulls the slider 242 to slide in the slide rail 241. Then, with the help of the second bracket 243 and the first bracket 2236, the nozzle 224 is driven to rotate, thereby realizing the adjustment of the spray angle. The steel structure components that have completed spraying are finally conveyed out of the device by the discharge unit 3. Throughout the entire operation, the base frame 21 provides installation support for each component of the rotating spray assembly 2, while the cover 234 protects the drive gear 233 and the driven gear 2234, thus extending the service life of the device.
