[0002] Anti-corrosion coatings are generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings. Conventional anti-corrosion coatings are conventional coatings that play an anti-corrosion role on metals and other materials under general conditions, while heavy-duty anti-corrosion coatings are a type of anti-corrosion coating that can be used in relatively harsh corrosive environments and has a longer protection period than conventional anti-corrosion coatings.

However, in actual use, although the existing spray device has basic spraying functions, it can generally only fix a cylinder of a specific size, which greatly limits the scope of application of the spray device. Therefore, it needs to be improved. Utility Model Content

[0039] The working principle and use process of this utility model:

[0040] First, the operator places the cylinder to be sprayed with paint between the two V-shaped plates 10 and starts the No. 1 pneumatic cylinder 7. As the No. 1 pneumatic cylinder 7 runs, the movable block 8 and the connecting column 9 will start to move, and the movement of the connecting column 9 will drive the active rod 4, causing the active rod 4 to start to rotate around the central axis 3. At the same time, the two ends of the active rod 4 also drive the two driven rods 5, causing the two driven rods 5 to rotate, and the other ends of the two driven rods 5 will respectively drive the two moving blocks 2, causing the two moving blocks 2 and the two V-shaped plates 10 to start to move toward each other along the inner surface of the placement table 1. Finally, when the two V-shaped plates 10 contact the outer surface of the cylinder, the cylinder will be fixed between the two V-shaped plates 10.

[0041] Then the operator starts the paint pump 15 and the second pneumatic cylinder 18. The operation of the paint pump 15 will cause the heavy anti-corrosion paint inside the paint bucket 13 to enter the paint pump 15 through the feed pipe 16, and then enter the interior of the hollow block 22 through the discharge pipe 17, the hose 20, and the fixed box 19. The operation of the second pneumatic cylinder 18 will cause the fixed box 19 to start moving downward as a whole. When the nozzle 23 moves into the interior of the cylinder, the operator opens the nozzle 23 and starts the drive motor. Machine 25, as the driving motor 25 runs, the circular shaft 26 and the driving gear 27 will start to rotate, and the driven gear 24 and the hollow block 22 as a whole will start to rotate under the drive of the driving gear 27. In this process, the heavy anti-corrosion paint inside the hollow block 22 will be sprayed onto the inner surface of the cylinder through the nozzle 23. Finally, under the joint action of the paint pump 15, the fixed box 19, the nozzle 23 and the driving gear 27, the nozzle 23 will evenly spray the heavy anti-corrosion paint onto the inner wall of the cylinder.
