Metal products are made into products with different shapes and uses through various processing technologies, such as casting, forging, cutting, welding, stamping, polishing, etc. In order to form a protective barrier on the metal surface to prevent the corrosion of the metal by moisture, oxygen, chemical substances, etc. in the environment and extend the service life of metal products, a coating spraying device for metal product processing is required.
[0003] During the use of traditional coating spraying devices for metal product processing, the coating is pumped from the storage tank into the spray gun through a delivery pipeline. The high-pressure air flow inside the spray gun atomizes the coating into fine droplets and evenly sprays them on the metal surface. The movement of the spray gun can be controlled by a manipulator or an automated track system to ensure that each part is evenly covered.

[0030] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
[0031] Referring to Figures 1-3 , an embodiment provided by the present invention: A coating spraying device for metal product processing, including a housing 1, a cross bracket 3 is rotatably connected inside the housing 1, a limiting groove 2 is opened inside the housing 1, a limiting component is arranged on one side of the cross bracket 3, and the limiting component is used to limit the cross bracket 3 in the housing 1. A first motor 4 is fixedly connected to one side of the cross bracket 3, a threaded rod 5 is fixedly connected to the output end of the first motor 4, a sleeve 8 is threadedly connected to the outer wall of the threaded rod 5, a support rod 9 is rotatably connected to the outer wall of the sleeve 8, one end of the support rod 9 is rotatably connected to a clamping plate 10, a limiting block 25 is fixedly connected to one side of the clamping plate 10, and the outer wall of the limiting block 25 slides inside the cross bracket 3. A first gear 6 is fixedly connected to one side of the cross bracket 3, a second motor 14 is fixedly connected to one side of the housing 1, a second gear 15 is fixedly connected to the output end of the second motor 14, and the second gear 15 meshes with the outer wall of the first gear 6. A material conveying pipe 12 is fixedly connected inside the housing 1, a connecting pipe 11 is fixedly connected to one end of the material conveying pipe 12, and a nozzle 13 is fixedly connected to the outer wall of the material conveying pipe 12. The limiting component includes a limiting wheel 7, one end of the limiting wheel 7 is rotatably connected inside the cross bracket 3, and the outer wall of the limiting wheel 7 slides inside the limiting groove 2;
[0032] Specifically, first, the part to be sprayed is steadily placed on the outer wall of the clamping plate 10. Subsequently, the first motor 4 is started, and the output end drives the threaded rod 5 to rotate. As the threaded rod 5 rotates, the sleeve 8 is driven to move. The sleeve 8 drives the clamping plate 10 to expand through the support rod 9. At the same time, the clamping plate 10 is limited inside the cross bracket 3 through the limiting block 25 to ensure that the part is firmly fixed. Then, the second motor 14 is started, and the output end drives the second gear 15 to rotate. The second gear 15 drives the cross bracket 3 to rotate through the first gear 6, thereby driving the part to rotate. The cross bracket 3 slides in the limiting groove 2 through the limiting wheel 7, thereby limiting the cross bracket 3 to ensure its stability during rotation. At this time, the connecting pipe 11 is connected to the paint tank, and the paint is evenly sprayed out from the nozzle 13 through the material conveying pipe 12 and covers the surface of the part. During the spraying process, the paint is evenly distributed in a fine mist at each corner of the part, forming a uniform protective coating.
[0033] Referring to Figure 4, a filter barrel 16 is fixedly connected to the outer wall of the housing 1. A partition 17 is fixedly connected inside the filter barrel 16. A frame 18 is arranged inside the filter barrel 16. A filter net 19 is fixedly connected inside the frame 18. The bottom of the frame 18 is attached to the top of the partition 17. A top cover 20 is arranged at the top of the filter barrel 16. A fan 21 is arranged inside the top cover 20. A first support column 22 is fixedly connected to the bottom of the top cover 20. A second support column 23 is slidably connected inside the first support column 22. A spring 24 is arranged inside the first support column 22. The bottom of the second support column 23 is attached to the top of the frame 18. One end of the spring 24 is fixedly connected inside the first support column 22, and the other end of the spring 24 is fixedly connected to the top of the second support column 23;
[0034] Specifically, when the fan 21 is started, the harmful gases generated by the volatilization of the paint in the housing 1 are inhaled into the filter barrel 16 to ensure the safety of the operating environment. After these gases enter the filter barrel 16, they are filtered by the filter net 19 in the filter barrel 16 to effectively remove harmful substances, and then the clean air is discharged. The filter net 19 is fixed in the filter barrel 16 and is limited by the frame 18 to ensure its stable position. In order to prevent gaps from occurring between the filter net 19 and the partition 17, resulting in incomplete filtration, the first support column 22 and the second support column 23 at the bottom of the top cover 20 work together to firmly support the frame 18. The second support column 23 is supported by the tension of the spring 24 inside the first support column 22, so that the second support column 23 can always tightly press against the frame 18 to prevent any displacement.
[0035] Working principle: When using this coating spraying device for metal product processing, first place the part to be sprayed on the outer wall of the clamping plate 10. Then, the output end of the first motor 4 is started to drive the threaded rod 5 to rotate. When the threaded rod 5 rotates, it drives the sleeve 8 to move. The sleeve 8 drives the clamping plate 10 to expand through the support rod 9 to fix the part. The clamping plate 10 is limited inside the cross bracket 3 through the limiting block 25. Then, the output end of the second motor 14 drives the second gear 15 to rotate. The second gear 15 drives the cross bracket 3 to rotate through the first gear 6, thereby driving the part to rotate. The cross bracket 3 slides in the limiting groove 2 through the limiting wheel 7 to limit the rotation of the cross bracket 3. Then, the connecting pipe 11 is connected to the paint tank, and the paint is sprayed evenly on the surface of the part through the nozzle 13 from the feed pipe 12. At the same time, the fan 21 inhales the harmful gases generated by the volatilization of the paint in the housing 1 into the filter barrel 16, so that the paint is filtered by the filter net 19 in the filter barrel 16 and then discharged, reducing the harm to the operator. The filter net 19 is limited in the filter barrel 16 through the frame 18, and the frame 18 is pressed against by the cooperation of the first support column 22 and the second support column 23 at the bottom of the top cover 20 to prevent gaps from occurring between the frame 18 and the partition 17, resulting in incomplete filtration. The second support column 23 is supported by the tension of the spring 24 inside the first support column 22, so that the second support column 23 can always press against the frame 18.
[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are 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 recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
