These coatings usually have excellent adhesion and chemical inertness, and are used to improve the corrosion resistance, wear resistance and high temperature resistance of metal surfaces, and extend the service life of parts.
[0003] The metal surface plasma spraying powder discharge device is a device used to control and transport powder coatings. It is mainly used in the plasma spraying process and is one of the key pieces of equipment in the spraying process. By precisely controlling the powder delivery and flow rate, it ensures the stability and quality of the spraying process and is one of the important coating preparation technologies in modern industry.
[0004] Existing metal surface plasma spraying powder discharge devices lack a fixed structure during use, making it difficult to maintain the correct position of the workpiece conveyed on the conveyor belt. If the workpiece is unstable or shifts during the spraying process, it may result in uneven coating, which may affect the coating thickness, adhesion, and final appearance and performance. Utility Model Content

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] Reference Figure 1 - Figure 3One embodiment of this utility model provides a metal surface plasma spraying powder discharge device, including a U-shaped frame 1, an electric roller 2 rotatably connected to the inner wall of the U-shaped frame 1, a conveyor belt 3 provided on the outer wall of the electric roller 2, a first motor 4 fixedly connected inside the U-shaped frame 1, a first rotating rod 5 fixedly connected to the output end of the first motor 4, a gear 6 fixedly connected to the outer wall of the first rotating rod 5, one end of the first rotating rod 5 rotatably connected inside the U-shaped frame 1, and a sliding column 7 slidably connected inside the U-shaped frame 1. A rack 8 is fixedly connected to the outer wall of the sliding column 7, and the outer wall of the rack 8 meshes with the outer wall of the gear 6. A circular hole 10 is opened on the inner wall of the U-shaped frame 1. A limit cap 9 is fixedly connected to the outer wall of the sliding column 7. A U-shaped frame 11 is fixedly connected to one end of the sliding column 7. A rotating wheel 12 is rotatably connected to the inner wall of the U-shaped frame 11. A spraying assembly is provided on the upper surface of the U-shaped frame 1. The spraying assembly is used to perform surface plasma spraying on metal. The spraying assembly includes a spray box 13, and a spraying machine 14 is fixedly connected to the inner wall of the spray box 13.
[0026] Specifically, when the electric roller 2 starts, it rotates on the inner wall of the U-shaped frame 1, which in turn drives the conveyor belt 3 to rotate and transport the metal products placed on the conveyor belt 3. The U-shaped frame 1 can fix the first motor 4, ensuring that the first motor 4 remains stable during operation. The start of the first motor 4 can drive the first rotating rod 5 to rotate, which in turn drives the gear 6 to rotate. The rotation of the gear 6 can convert the rotational motion of the first rotating rod 5 into the horizontal movement of the sliding column 7 through the rack 8. The limit cap 9 is fixed on the outer wall of the sliding column 7, which can limit the sliding column 7 and prevent the sliding column 7 from sliding out of the U-shaped frame 1. The round hole 10 is used to provide space for the sliding column 7 to move. The rotating wheel 12 rotates on the inner wall of the U-shaped frame 11, which can ensure that the metal products are kept in the correct position and prevent the metal products from getting stuck during the conveying process. The U-shaped frame 1 can fix the spray box 13, which in turn fixes the spraying machine 14, which is used to spray the products.
[0027] Reference Figure 1 The inner wall of the U-shaped frame 1 is rotatably connected to the cleaning roller 15, and the outer wall of the cleaning roller 15 is rotatably connected to the outer wall of the conveyor belt 3.
[0028] Specifically, the cleaning roller 15 is used to clean the powder remaining above the conveyor belt 3, and it rotates on the inner wall of the U-shaped frame 1 as the conveyor belt 3 rotates.
[0029] Reference Figure 1 and Figure 4A blower box 16 is fixedly connected to the upper surface of the U-shaped frame 1, and a rectangular plate 17 is fixedly connected to the inner wall of the blower box 16. A second motor 18 is fixedly connected to the upper surface of the rectangular plate 17, and a disc 19 is fixedly connected to the output end of the second motor 18. A second rotating rod 20 is rotatably connected to one end of the disc 19. A slide rail 21 is fixedly connected to the lower surface of the rectangular plate 17. A slider 22 is slidably connected to the outer wall of the slide rail 21. One end of the second rotating rod 20 is rotatably connected to the lower surface of the slider 22. A fixing post 23 is fixedly connected to the lower surface of the slider 22. A fixing block 24 is fixedly connected to the lower end of the fixing post 23, and a fan 25 is fixedly connected to the lower surface of the fixing block 24.
[0030] Specifically, the U-shaped frame 1 can fix the air blower box 16, which in turn fixes the rectangular plate 17. The rectangular plate 17 is used to fix the second motor 18. The second motor 18 provides output to cause the disc 19 to rotate when started. The rotation of the disc 19 causes the second rotating rod 20 to rotate at the lower end of the disc 19 and on the lower surface of the slider 22. Since the slider 22 slides on the outer wall of the slide rail 21, the second rotating rod 20 rotates at the lower end of the disc 19 and on the lower surface of the slider 22, causing the slider 22 to move and slide on the outer wall of the slide rail 21. The fixing column 23 is used to connect the slider 22 and the fixing block 24. The fixing block 24 is used to fix the fan 25. The fan 25 is used to blow air onto the sprayed metal product when started, accelerating its drying and curing.
[0031] Working principle: When using this device, firstly, start the electric roller 2. The start of the electric roller 2 causes the conveyor belt 3 to run. At this time, the metal products to be sprayed can be placed above the conveyor belt 3 for conveying. During the conveying of the metal products, start the first motor 4. The start of the first motor 4 causes the first rotating rod 5 to rotate. The rotation of the first rotating rod 5 drives the gear 6 to rotate. The rotation of the gear 6 causes the rack 8 to move towards the conveyor belt 3. The movement of the rack 8 causes the sliding column 7 to slide inside the U-shaped frame 1, thereby causing the U-shaped frame 11 to move inward. This can be achieved by rotating the wheel 12 to ensure... The metal products being conveyed maintain the correct position. After the metal products pass under the spraying machine 14, the spraying machine 14 starts spraying the metal products conveyed above the conveyor belt 3. This ensures that the workpieces conveyed on the conveyor belt 3 maintain the correct position, and thus ensures that the powder is sprayed evenly and with a wide coverage area onto the workpiece surface, ensuring the quality and consistency of the coating. When the sprayed metal products pass under the blower box 16, the second motor 18 is started. The rotation of the second motor 18 causes the disc 19 to rotate, and the rotation of the disc 19 causes the second rotating rod 20 to rotate under the disc 19. At the same time, the second rotating rod 20 rotates on the lower surface of the slide rail 22, driven by the disc 19. Simultaneously, the disc 19 rotates on the lower surface of the slide rail 22, causing the slide rail 22 to slide against the outer wall of the slide rail 21. With the continuous output of the second motor 18, the disc 19 continues to rotate, causing the slide rail 22 to slide back and forth on the lower surface of the slide rail 21. This causes the slide rail 22 to drive the fixed block 24 to move back and forth via the fixed column 23, which in turn causes the fan 25 to move back and forth, uniformly blowing air onto the metal products sprayed above the conveyor belt 3. This achieves the desired effect. The reciprocating motion of fan 25 blows air onto the sprayed metal product, ensuring that the cooling airflow is evenly distributed across the entire product surface, accelerating its drying and curing. In actual use, this device not only ensures that the workpiece conveyed on conveyor belt 3 maintains the correct position, but also ensures that the powder is evenly and extensively sprayed onto the workpiece surface, ensuring the quality and consistency of the coating. In addition, the reciprocating motion of fan 25 blows air onto the sprayed metal product, ensuring that the cooling airflow is evenly distributed across the entire product surface, accelerating its drying and curing.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
