Technical Field

[0001] The utility model relates to the field of spraying equipment, and more specifically, to a spraying equipment for anti-corrosion coatings. Background Art

[0002] Anti-corrosion coatings are usually used on the surfaces of materials such as metal, wood, concrete, etc. to prevent them from corrosion caused by contact with water, oxygen, chemicals, etc. They have good adhesion, excellent corrosion resistance and good weather resistance. When in use, they are usually sprayed onto the surface of the material using spraying equipment.

[0003] Existing spraying equipment includes a feeding device for continuously feeding paint to the spray gun and a spray gun. When spraying, it is necessary to first fix the object to be sprayed with a clamp, and then put the paint into the feeding device. The paint will then be transported by the feeding device to the nozzle of the spray gun and sprayed out. After that, the nozzle uses pressure or centrifugal force to disperse the paint into uniform and fine droplets to spray the object.

[0004] Although this spraying method has high spraying efficiency, uniform coating and stable quality, due to the presence of the fixture during spraying, there will be dead corners in the fixture, which makes it more troublesome to re-coat the paint. In addition, color inconsistency is likely to occur during the second re-coating, which will lead to defective products.

[0005] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0020] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] A spraying device for anti-corrosion coating, such as Figure 1-Figure 3 As shown, it includes a placement plate 1 and a feeding device 2 fixedly connected to the placement plate 1, which can transport the paint. A placement table 3 for placing samples is fixedly connected to the placement plate 1. The feeding device 2 is provided with a spraying component for spraying the sample, and the placement table 3 is provided with a flipping component for flipping the sample. When the sample needs to be sprayed, the feeding device 2 can be turned on to feed the spraying component, and then the paint will be sprayed out from the spraying component for spraying. During the spraying process, the spraying component will stop spraying for a period of time to reset. At this time, the spraying component will trigger the flipping component to flip the sample, so that the surface that has not been sprayed before is on the upper side. Thereafter, the spraying component will spray the unsprayed surface, so that there is no need to clamp the object during spraying, and all-round spraying can be carried out to avoid spraying dead corners at the fixture, which requires secondary repainting.

[0022] like Figure 1-Figure 3 As shown, the spraying assembly includes an electric push rod 5 fixedly connected to the feeding device 2, a fixing frame 6 fixedly connected to the output end of the electric push rod 5, a connecting pipe 7 fixedly connected to the fixing frame 6, a plurality of nozzles 8 fixedly connected to the connecting pipe 7 and a delivery pipe 9 fixedly connected to the connecting pipe 7. The other end of the delivery pipe 9 is fixedly connected to the discharge end of the feeding device 2. The middle section of the delivery pipe 9 is spirally arranged to avoid the suspension of the delivery pipe 9 affecting the spraying operation. When the feeding device 2 is turned on, the electric push rod 5 is turned on synchronously, so that the output end of the electric push rod 5 drives the connecting pipe 7 and the nozzle 8 to move away from the feeding device 2. At this time, the nozzle 8 will spray the upper side and left and right sides of the sample. After the electric push rod 5 is extended to the set length, the feeding device 2 will be closed, and then the electric push rod 5 will retract and reset, thereby driving the nozzle 8 to reset, and the spraying operation can be performed in this reciprocating manner.

[0023] like Figure 1-Figure 3 As shown, the flipping assembly includes a positioning plate 10 connected to the placement table 3, a positioning block 11 rotatably connected to the positioning plate 10, a sliding rod 12 slidably connected to the positioning block 11, a pushing plate 13 fixedly connected to the side of the sliding rod 12 close to the feeding device 2, a blocking rod 14 rotatably connected to the feeding device 2, and a driving member arranged on both sides of the nozzle 8 and the pushing plate 13 for driving the sliding rod 12 to slide. The rotating positioning block 11 can make it more convenient to take out the sample. The driving member includes a magnet 15 fixedly connected to the nozzle 8, a magnet 2 16 fixedly connected to both sides of the pushing plate 13 for the magnet 15 to attract, and a spring 17 sleeved between the pushing plate 13 and the positioning block 11.

[0024] like Figure 1-Figure 3As shown, when the nozzle 8 moves away from the feeding device 2, magnet 1 15 will be attracted by magnet 2 16, and then the feeding device 2 is closed, and the nozzle 8 is also driven by the electric push rod 5 to reset. When the nozzle 8 resets and moves toward the feeding device 2, it will drive the push plate 13 to move toward the feeding device 2 at the same time. At this time, the spring 17 is in a stretched state, and when the upper side of the sample is pushed by the push plate 13, the lower side is blocked by the baffle 14, and the sample will flip over. Then the nozzle 8 continues to reset, magnet 1 15 is separated from magnet 2 16, and the spring 17 will drive the push plate 13 to reset. At this time, the sample will also drive the baffle 14 to rotate on the feeding device 2 due to its own gravity and friction. When the baffle 14 rotates, the sample will also slide and align on the placement table 3, so that the surface that has not been sprayed before is on the upper side. At this time, the feeding device 2 and the electric push rod 5 are turned on again to spray the unsprayed surface.

[0025] like Figure 1-Figure 3 As shown, the positioning plate 10 is slidably connected to the placement table 3, and the placement table 3 is threadedly connected with a threaded rod 18 for abutting the positioning plate 10. When the position of the push plate 13 needs to be changed, the threaded rod 18 can be rotated so that the threaded rod 18 no longer contacts the positioning plate 10, and then the position of the positioning plate 10 is adjusted. After the adjustment is completed, the threaded rod 18 can be rotated to abut the positioning plate 10, so as to adapt to different sample heights.

[0026] like Figure 1-Figure 3 As shown, a blocking block 19 is slidably connected to the connecting tube 7, a placing rod 20 is fixedly connected to the feeding device 2, and a stopper 21 is fixedly connected to the other end of the placing rod 20. When the stopper 21 contacts the blocking block 19, the blocking block 19 moves to the side of the feeding device 2. When the electric push rod 5 drives the push plate 13 to perform the first spraying operation and after spraying on both sides of the sample is completed, the electric push rod 5 continues to extend to make the block 21 contact with the blocking block 19. Thereafter, the electric push rod 5 extends again to make the blocking block 19 block both sides of the connecting tube 7. At this time, after the sample is flipped, the unsprayed surface of the sample is sprayed, and the nozzles 8 on both sides will not spray paint, thereby avoiding paint waste. After completing the sample spraying, the sample is taken out and the blocking block 19 is manually reset.

[0027] like Figure 1-Figure 3 As shown, a through slot 22 is provided on the placement table 3, and a plurality of rollers 23 are rotatably connected to the through slot 22. When the sample is turned over, the rollers 23 cooperate with the blocking rod 14 so that the sample can be straightened more quickly.

[0028] Working principle: When it is necessary to spray the sample, the feeding device 2 can be turned on to feed the connecting pipe 7. When the feeding device 2 is turned on, the electric push rod 5 is turned on synchronously, so that the output end of the electric push rod 5 drives the connecting pipe 7 and the nozzle 8 to move away from the feeding device 2. At this time, the nozzle 8 will spray the upper side and the left and right sides of the sample. After the electric push rod 5 is extended to the set length, the magnet 15 will be attracted by the magnet 2 16, and then the feeding device 2 is closed. The nozzle 8 is also driven by the electric push rod 5 to reset. When the nozzle 8 resets and moves to the side of the feeding device 2, it will drive the push plate 13 to move to the side of the feeding device 2 at the same time. At this time, the spring 17 is in a stretched state, and when the upper side of the sample is pushed by the push plate 13, the lower side is blocked by the baffle 14, and the sample will flip over. Then the nozzle 8 continues to reset, and the magnet 15 and the magnet 2 16 are separated. The spring 17 will drive the push plate 13 to reset. At this time, the sample will also drive the baffle 14 to rotate on the feeding device 2 due to its own gravity and friction. When the baffle 14 rotates, the sample will slide and align on the roller 23, so that the surface that has not been sprayed before is on the upper side. At this time, the feeding device 2 and the electric push rod 5 can be turned on again to spray the unsprayed surface. The spraying operation can be completed by this reciprocating motion.

[0029] When the electric push rod 5 drives the push plate 13 to perform the first spraying operation, and after spraying on both sides of the sample is completed, the electric push rod 5 continues to extend to make the block 21 contact with the blocking block 19. Thereafter, the electric push rod 5 extends again to make the blocking block 19 block both sides of the connecting pipe 7. At this time, after the sample is turned over, the unsprayed surface of the sample is sprayed, and the nozzles 8 on both sides will not spray paint. After completing the sample spraying, the sample is taken out and the blocking block 19 is manually reset.

[0030] In this way, there is no need to clamp the object during spraying, and all-round spraying can be carried out, avoiding the problem of spraying dead corners at the fixture and the need for secondary repainting, thereby reducing the occurrence of defective products, and the blocking block 19 can be used to block the connecting pipe 7 to reduce paint waste during spraying.
