[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figures 1-3 , an embodiment provided by the present invention: A spraying device for an anti-corrosion coating of a fire door, including a bracket 1, a storage tank 2 is fixedly connected to the middle of the bracket 1, a spraying assembly is arranged on one side of the storage tank 2, a second motor 17 is fixedly connected to the middle of the bracket 1, the output end of the second motor 17 is fixedly connected to a turntable 18, a fire door 4 is arranged on the top of the turntable 18, two first electric push rods 7 are fixedly connected to the top of the bracket 1, a support plate 8 is arranged above the bracket 1, the other ends of the two first electric push rods 7 are fixedly connected to the bottom of the support plate 8, a first motor 9 is fixedly connected to the top of the support plate 8, the output end of the first motor 9 is fixedly connected to a rotating plate 10, and a clamping assembly is arranged in the middle of the rotating plate 10.

[0032] Specifically, by placing the fire door 4 above the turntable 18, then spraying both sides of the fire door 4 through the spraying assembly, and then driving the turntable 18 to rotate by the second motor 17, it is possible to spray the other two sides of the fire door 4. Then, drive the support plate 8 to move above the bracket 1 through the first electric push rod 7, so that the support plate 8 drives the rotating plate 10 to move synchronously, and the rotating plate 10 moves to both sides of the fire door 4. Then, after clamping the fire door 4 through the clamping assembly, drive the support plate 8 to move upward through the first electric push rod 7, so that the support plate 8 drives the clamping assembly to move synchronously with the fire door 4. When reaching a certain height, drive the rotating plate 10 to rotate through the first motor 9, so that the rotating plate 10 drives the clamping assembly to rotate synchronously, realizing the flipping of the fire door 4. When the fire door 4 rotates to be perpendicular to the bracket 1, stop rotating, and then spray both sides of the fire door 4 through the spraying assembly. By rotating and flipping the fire door 4, it is possible to spray the coating on all four sides of the fire door 4, so as to solve the problem that the four sides of the fire door 4 cannot be sprayed, and realize that the anti-corrosion coating can be wrapped around the outer periphery of the fire door 4, thereby extending the service life of the fire door 4.

[0033] Referring to Figures 1-3, the spraying assembly includes a discharge pipe 3, the discharge pipe 3 is fixedly connected to one side of the storage tank 2, and the other end of the discharge pipe 3 is fixedly connected with a plurality of nozzles 12. The top of the bracket 1 is fixedly connected with an electric push rod two 16, and the other end of the electric push rod two 16 is fixedly connected to the bottom of the plurality of nozzles 12. The fire door 4 does not contact the electric push rod two 16. The clamping assembly includes a threaded rod 14, the threaded rod 14 is threadedly connected to the middle of the rotating plate 10, one end of the threaded rod 14 is fixedly connected with a rotating wheel 15, the other end of the threaded rod 14 is rotatably connected to a push plate 13, and the other end of the push plate 13 is fixedly connected with a clamping block 11.

[0034] Specifically, the anti-corrosion paint liquid inside the storage tank 2 is conveyed to the nozzle 12 through the discharge pipe 3, and then the side of the fire door 4 is sprayed through the nozzle 12. And by arranging a spraying assembly on both sides of the storage tank 2, the two sides of the bracket 1 can spray the fire door 4 simultaneously, improving the spraying efficiency. When the spraying of the four sides of the fire door 4 is completed, the electric push rod one 7 drives the rotating plate 10 to move to one side of the fire door 4, and then by rotating the rotating wheel 15, the rotating wheel 15 drives the threaded rod 14 to rotate in the middle of the rotating plate 10, so that the threaded rod 14 drives the clamping block 11 and the push plate 13 at the other end to move. The two groups of push plates 13 drive the clamping blocks 11 to move towards each other, realizing the clamping of the fire door 4, so that during the flipping process of the fire door 4, good stability can be provided for the fire door 4, facilitating the spraying of the surface of the fire door 4 by the nozzle 12.

[0035] Refer to Figure 1 , Figure 3 and Figure 4 , a drainage groove 19 is opened at the top of the bracket 1, a collection hole 20 is opened at the top of the bracket 1, a collection box 5 is slidably connected to the bottom of the bracket 1, a sliding assembly is arranged at the top of the collection box 5, the sliding assembly includes a slider 21, the slider 21 is fixedly connected to the top of the collection box 5, a chute 22 is opened in the middle of the bracket 1, and the slider 21 is slidably connected to the middle of the chute 22. One side of the collection box 5 is rotatably connected with a handle 6, and the collection box 5 is arranged below the collection hole 20.

[0036] Specifically, during the spraying process around the fire door 4, a part of the paint liquid will be sprayed on the top of the bracket 1, resulting in a very messy surface on the top of the bracket 1. By opening a drainage groove 19 on the top of the bracket 1, the paint liquid on the surface of the bracket 1 can be collected in the middle of the drainage groove 19, and then flow to the collection hole 20. Then, it enters the interior of the collection box 5 arranged at the bottom of the collection hole 20 through the collection hole 20. After the spraying is completed, by pulling the handle 6 and sliding the slider 21 in the middle of the chute 22, the collection box 5 can be slid out from the middle of the bracket 1 to achieve the centralized treatment of the paint liquid. The centralized treated paint liquid can be used to spray the fire door 4 again to achieve the full utilization of resources and avoid waste of resources.

[0037] Working principle: Place the fire door 4 on the top of the turntable 18, and then spray the anti-corrosion coating on both sides of the fire door 4 through the two discharge pipes 3 at the same time. Then, drive the turntable 18 to rotate by the second motor 17, so that the spray head 12 can spray around the fire door 4. Then, drive the support plate 8 to move on the top of the bracket 1 by the first electric push rod 7, so that the rotating plate 10 moves to one side of the fire door 4. Then, rotate the rotating wheel 15, and drive the clamping blocks 11 to move towards the opposite side respectively through the two push plates 13 to clamp the fire door 4. Then, drive the support plate 8 to move upward by the first electric push rod 7, so that the rotating plate 10 drives the fire door 4 to move synchronously on the top of the bracket 1. When reaching a certain height, drive the rotating plate 10 to rotate by the first motor 9 to turn over the fire door 4. Stop when the fire door 4 rotates to an angle perpendicular to the bracket 1. Then, drive the push plate 13 to move on the top of the bracket 1 by the second electric push rod 16 to spray both sides of the fire door 4. After the spraying of these two sides is completed, the fire door 4 can be rotated again by the first motor 9 to make the fire door 4 parallel to the bracket 1. Then, move the fire door 4 to the top of the support plate 8 by the first electric push rod 7, and reverse-rotate the rotating wheel 15 to release the clamping of the fire door 4. Then, the spraying work of the fire door 4 is completed. In this way, the spraying of all around the fire door 4 can be realized to solve the problem that the fire door 4 cannot be sprayed around.

[0038] During the spraying process of the fire door 4, a part of the paint liquid is sprayed on the top of the bracket 1, resulting in a very messy surface on the top of the bracket 1. By opening a drainage groove 19 on the top of the bracket 1, the paint liquid on the surface of the bracket 1 can be collected in the middle of the drainage groove 19, and then flow to the collection hole 20, and then enter the interior of the collection box 5 arranged at the bottom of the collection hole 20 through the collection hole 20, realizing the centralized collection of the paint liquid, which can reduce the mess and pollution on the surface of the bracket 1, improve the cleanliness of the working environment. The centralized collected paint liquid can be processed and recycled, realizing the full utilization of resources and avoiding waste of resources.
