[0001] This utility model relates to the field of fastener processing technology, and in particular to an anti-corrosion spraying device for fastener processing. Background Technology

[0002] Fasteners are an indispensable part of mechanical equipment, and their quality and performance play a crucial role in the overall stability and safety of the equipment. Furthermore, in harsh environments such as humidity and acid / alkali conditions, coatings can effectively prevent fastener corrosion, thus requiring anti-corrosion spraying treatment. Coatings also improve the wear resistance of fasteners, reducing wear caused by friction. In addition, coatings enhance the aesthetics of fasteners, making them more suitable for the aesthetic requirements of their application.

[0003] In existing technologies, traditional paint mist collection equipment such as paint mist felt, plate and frame filters, and bag filters are insufficient in terms of paint mist collection efficiency, especially in the process of treating high-concentration paint mist, which can easily lead to equipment contamination and filter clogging, requiring complex and cumbersome cleaning and maintenance; and when one batch of fasteners is coated, there is a waiting time before the next batch is coated, which reduces efficiency. Therefore, we propose an anti-corrosion spraying device for fastener processing to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-4As shown, an anti-corrosion spraying device for fastener processing is disclosed, comprising a spraying box 1, a partition 2 fixedly connected inside the spraying box 1, dividing the spraying box 1 into upper and lower areas, a circular frame 9 fixedly connected to the top of the partition 2, a first motor 10 fixedly connected inside the circular frame 9, a circular hole opened at the top of the circular frame 9, the inner wall of the circular hole being rotatably connected to the outer wall of the output shaft of the first motor 10, the circular frame 9 protecting the first motor 10, and a rotating rod 11 fixedly connected to the top of the output shaft of the first motor 10. Two frames 12 are fixedly connected to the top of 11. A second motor 13 is fixedly connected inside the two frames 12. The frames 12 are circular and protect the second motor 13. A connecting plate 14 is fixedly connected to the top of the output shaft of each of the two second motors 13. A U-shaped frame 15 is fixedly connected to the outer wall of each of the two connecting plates 14. Multiple support rods 16 are fixedly connected to the inner wall of each of the two U-shaped frames 15. A stainless steel mesh 17 is placed on the top of the multiple support rods 16 and supports the stainless steel mesh 17.

[0022] The spray box 1 is equipped with a partition mechanism inside. The paint mist adsorption mechanism includes two support bars 3. The outer walls of the two support bars 3 are fixedly connected to the inner wall of the spray box 1. U-shaped frames 4 are placed on the top of the two support bars 3 and the bottom of the inner wall of the spray box 1. Multiple corrugated cardboard 5 are fixedly connected to the inner walls of the two U-shaped frames 4. The U-shaped frames 4 can be disassembled and replaced. The multiple corrugated cardboard 5 are arranged vertically to form a folded return air duct.

[0023] The outer walls of the partition 2 and one of the U-shaped frames 4 are provided with rectangular holes 6. The inner wall of the spray box 1 is fixedly connected with an activated carbon filter 7. The outer wall of the spray box 1 is fixedly connected with an exhaust pipe 8. One end of the exhaust pipe 8 is fixedly connected with a fan. The exhaust pipe 8 is located on one side of the activated carbon filter 7. The top of the spray box 1 is fixedly connected with an air inlet pipe.

[0024] The spray box 1 is equipped with a paint mist adsorption mechanism. The partition mechanism includes a threaded rod 22. One end of the threaded rod 22 is fixedly connected to the inner wall of the spray box 1. A baffle 19 is slidably sleeved on the outer wall of the threaded rod 22. A rectangular vertical groove 18 is opened on the outer wall of the baffle 19. The inner wall of the rectangular vertical groove 18 is slidably connected to the outer wall of the threaded rod 22. A nut 20 is threadedly sleeved on the outer wall of the threaded rod 22. The nut 20 fixes the baffle 19 in the spray box 1 by extrusion. The outer wall of the nut 20 is pressed against the outer wall of the baffle 19. Three hinged doors 21 are connected to the outer wall of the spray box 1. Existing door locks are installed on the outer walls of the three doors 21. A spray gun is installed inside the spray box 1.

[0025] Working principle: In use, multiple fasteners are placed on the stainless steel mesh 17 on the right side. The nut 20 is rotated to release the fixation of the baffle 19. The baffle 19 is tilted or moved up and down via the rectangular vertical groove 18 to change its position, facilitating subsequent paint mist collection without affecting the painting process. The first motor 10 drives the rotating rod 11, which in turn rotates the two circular frames 9 and the two connecting plates 14, causing the two U-shaped frames 15 to switch positions, positioning the fasteners below the spray gun. The existing pressure pump draws the anti-corrosion paint from the paint bucket to the spray gun. Inside the spray gun, the anti-corrosion coating is atomized into fine particles and sprayed downwards to treat multiple fasteners on the stainless steel mesh 17. During this process, the second motor 13 drives the connecting plate 14 and the U-shaped frame 15 to rotate slowly. The rotation of the U-shaped frame 15 drives the stainless steel mesh 17 and multiple fasteners to rotate, which helps to achieve uniform spraying. At the same time, the fan operates to form an air extraction process through the exhaust pipe 8, which draws excess paint mist from the spray box 1 through the airflow from the rectangular hole 6 to multiple corrugated cardboard 5. The multiple corrugated cardboard 5 adsorb the paint mist, and then the airflow passes through the activated carbon filter 7 to remove odors and some paint mist, thus achieving the function of collecting paint mist.

Furthermore, the structure and principle of the components known to those skilled in the art can be learned by those skilled in the art through technical manuals or conventional experimental methods.
