Description

Technical Field

[0001] This utility model relates to the field of spraying equipment, and in particular to a rust-preventive paint spraying equipment. Background Technology

[0002] Metal materials are widely used in industrial manufacturing, infrastructure construction, transportation, and energy development due to their high strength and low cost. However, metals are highly susceptible to oxidation and corrosion in humid, salt spray, and acid rain environments, leading to decreased structural strength, shortened service life, and even safety accidents. Therefore, rust-preventive paint spraying has become a key protective measure against metal corrosion, and rust-preventive paint spraying equipment is the core tool for achieving efficient and high-quality coating operations. After curing on the metal surface, rust-preventive paint forms a dense coating that effectively blocks corrosive substances such as moisture, oxygen, chloride ions, and sulfur dioxide from contacting the metal, preventing electrochemical reactions. Traditional manual spraying is inefficient; rust-preventive paint spraying equipment, as specialized equipment, significantly improves the mechanization, automation, and professionalization of coating operations. However, changing paint cans during rust-preventive paint spraying is inconvenient; therefore, a rust-preventive paint spraying device is provided. Utility Model Content

Paint tanks 14 are disposed between the support frames 11, and the paint tanks 14 contain rust-preventive paint. Figure 1 As shown, to facilitate the movement of the entire device, several casters 12 are rotatably mounted on the lower surface of the base 1; a push handle 13 is fixedly mounted on one side of the support frame 11, and the push handle 13 connects the two support frames 11. The operator can move the device to the target construction area by pushing the push handle 13; for example... Figure 2 As shown, a telescopic groove 111 is provided on the side wall of the support frame 11 near the lower end, and a slide rail groove 112 is provided on the side wall of the support frame 11 near the upper end. It also includes: a spraying unit 2, which is slidably disposed between the two side support frames 11. The spraying unit 2 draws in the anti-rust paint from the paint tank 14 and then performs spraying; such as Figure 2 , Figure 4 As shown, the spraying unit 2 includes a support plate 21, which is slidably installed between two side slide rail grooves 112. Limiting blocks 211 are symmetrically fixedly installed on both sides of the support plate 21, and are slidably installed within the slide rail grooves 112. Each limiting block 211 has a T-shaped structure adapted to the slide rail groove 112. A first cylinder 212 is fixedly installed on the top surface of the support frame 11. The movable rod of the first cylinder 212 extends into the slide rail groove 112 and is fixed to the limiting block 211. When the paint can 14 needs to be replaced, the first cylinder 21 pulls the support plate 21 upwards, causing the conveying pipe 22 to rise, allowing the new paint can 14 to be removed and replaced. The first cylinder 212 then resets, pushing the support plate 21 downwards, allowing the conveying pipe to... One end of the conveying pipe 22 is inserted into the paint can 14; a conveying pipe 22 is fixedly installed at the center of the support plate 21. The conveying pipe 22 has an L-shaped structure. One end of the conveying pipe 22 is inserted into the paint can 14, and the other end of the conveying pipe 22 is made of flexible material. A nozzle 221 is fixedly installed at the other end of the conveying pipe 22. A retaining ring 222 is fixedly installed on one side of the nozzle 221. The retaining ring 222 has a trumpet-shaped structure. The operator holds the conveying pipe 22 close to the nozzle 221 and adjusts the spraying position through the flexible part of the conveying pipe 22. In this utility model, the flexible part of the conveying pipe 22 is preferably made of flexible rubber material. The trumpet-shaped structure of the retaining ring 222 forms a local negative pressure area, which guides the paint mist to concentrate forward and blocks some of the paint particles that splash in the opposite direction. It also includes: a clamping part 3, which includes two clamping blocks 31. Each clamping block 31 is slidably provided with a support frame 11. The clamping blocks 31 push the paint can 14 to perform centering and clamping; such as Figure 2 , Figure 3As shown, the clamping block 31 is slidably installed in the telescopic groove 111.

The piston rod of the second cylinder 32 extends into the telescopic groove 111 and is fixed with the clamping block 31. A fitting groove 311 is provided on the other side of the clamping block 31. The fitting groove 311 has a concave arc structure. An angle 312 is provided at the edge of the other side of the clamping block 31. The concave arc fitting groove 311 fits against the side wall of the paint can 14, increasing the contact area with the paint can 14 and making the clamping more stable.

[0016] The paint can 14 is pushed between the two clamping blocks 31. The second cylinder 32 pushes the clamping blocks 31 to move, so that the fitting groove 311 on the clamping blocks 31 fits and clamps the paint can 14. The second cylinder 32 provides a constant clamping force, which can stably and firmly clamp the paint can 14. When replacing the paint can 14, the second cylinder 32 pushes the clamping blocks 31 back to remove the paint can 14. The paint can 14 can be quickly replaced in the above way.

[0017] A limiting plate 4 (such as) is fixedly installed on the surface of the base 1. Figure 5 As shown), the limiting plate 4 is used to limit the paint can 14 when it is pushed between the two clamping blocks 31. When the paint can 14 and the limiting plate 4 are in contact, it means that the paint can 14 has been pushed into the correct position. At this time, the fitting groove 311 can fit perfectly on the surface of the paint can 14.
