In order to significantly improve the wear resistance, corrosion resistance, oxidation resistance and other properties of metal components and extend their service life in complex environments, spraying polymer coatings on the surface of metal components has become a crucial and effective treatment method.

[0003] However, existing metal components use a large amount of polymer coatings when spraying polymer coatings. Their spraying equipment cannot effectively recycle and reuse the residual dripping coatings, resulting in waste of excess coatings. At the same time, the polymer coatings are not stirred during use, which can lead to sedimentation and clumping, resulting in inconsistent coating concentrations and further reducing coating quality.

[0004] To address this, a device for uniformly spraying polymer coatings on metal components is proposed. Utility Model Content

This device can solve the problems of existing metal components where a large amount of polymer coating is used during the spraying process, and the spraying device cannot effectively recycle and reuse the residual dripping coating, resulting in waste of excess coating. In addition, the polymer coating is not stirred during use, which leads to sedimentation and clumping, resulting in inconsistent coating concentration and further reducing coating quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A uniform spraying device for polymer coating of metal components includes a platform 1, a bearing and recycling mechanism 2 is provided on the top of the platform 1, a support plate 3 is bolted to the rear side of the platform 1, and a spraying structure 4 is provided on the top side inside the support plate 3.

[0027] The carrying and recycling mechanism 2 includes a paint cylinder 21 embedded in the top of the platform 1. The rear side of the paint cylinder 21 is connected to the front side of the bottom of the spraying structure 4. A motor 22 is bolted to the bottom of the paint cylinder 21. A shaft 23 is fixedly connected to the output end of the motor 22. The top of the shaft 23 passes through the bottom of the paint cylinder 21 and extends into the interior. A connecting sleeve 24 is bolted to the outside of the shaft 23. A stirring rod 25 is fixedly connected to both the front and rear sides of the connecting sleeve 24. A hopper 26 is connected to the top of the paint cylinder 21. A filter purification screen 27 is bolted to the top of the hopper 26. A placement net 28 is snapped onto the top of the filter purification screen 27.

[0028] In this embodiment: by setting up a spraying structure 4 and a carrying and recycling mechanism 2, the metal component to be sprayed with a polymer coating is first placed on the placement net 28. The motor 22 is started, and the motor 22 drives the shaft 23 to rotate. The shaft 23 drives the connecting sleeve 24 and the stirring rod 25 to rotate, stirring the polymer coating in the coating cylinder 21 to prevent the coating from settling and clumping, and to ensure uniform coating concentration. The spraying structure 4 starts working, sucking up the coating in the coating cylinder 21, and then uniformly spraying the metal component placed on the surface of the placement net 28. During the spraying process, excess coating will drip down and be filtered and purified by the filter and purification net 27, and then flow back into the coating cylinder 21 through the discharge hopper 26 to realize the recycling and reuse of the coating. After one side of the metal component is sprayed, the operator can use a tool to flip it over and spray it again to ensure that the surface of the metal component is uniformly covered by the polymer coating, ultimately improving the uniformity and stability of the coating and enhancing the performance and service life of the metal component.

[0029] Specifically, such as Figure 4 As shown, the spraying structure 4 includes a suction pipe 41 connected to the rear side of the paint cylinder 21, and a spraying pump 42 is bolted to the rear side of the bottom of the platform 1. The absorption end of the spraying pump 42 is connected to the rear side of the suction pipe 41.

[0030] Specifically, such as Figure 4 As shown, the output end of the spray pump 42 is connected to the output pipe 43, and the end of the output pipe 43 away from the spray pump 42 passes through the top of the support plate 3.

[0031] Specifically, such as Figure 4 As shown, the bottom of the output pipe 43 is connected to a spray plate 44, and the bottom of the spray plate 44 is connected to a uniform spray head 45, which is located at the top of the placement net 28.

[0032] In this embodiment: by setting up the spraying structure 4, after starting the spraying pump 42, the paint is drawn from the paint cylinder 21 through the suction pipe 41. The suction pipe 41 connects the paint cylinder 21 and the spraying pump 42 to ensure smooth paint transfer. After being pressurized by the spraying pump 42, the drawn paint is delivered to the spraying plate 44 through the output pipe 43. After receiving the paint, the spraying plate 44 sprays the paint evenly onto the metal element placed on the top of the placement net 28 through the uniformly distributed uniform spraying heads 45 at the bottom, so as to achieve uniform spraying of the metal element and ensure that the polymer coating can be uniformly covered.

[0033] Specifically, such as Figure 1 As shown, suspension rods 5 are bolted to both sides of the top side inside the support plate 3, and supplementary lights 6 are bolted to the bottom of the suspension rods 5.

[0034] Specifically, such as Figure 5 As shown, a flow divider hole 7 is provided on the outer side of the stirring rod 25. The flow divider hole 7 is in the shape of a circular groove.

[0035] In this embodiment: by setting up a suspension rod 5, a supplementary light 6, and a diversion hole 7, the suspension rod 5 is installed on both sides of the top inside the support plate 3. Its function is to fix the supplementary light 6 and place it in a suitable position. During the spraying operation, the supplementary light 6 provides sufficient light so that the operator can clearly observe the spraying of the metal components and promptly detect any problems such as uneven spraying, thereby ensuring the spraying quality. In addition, when the stirring rod 25 rotates and stirs the paint, the circular diversion hole 7 on its outer side can make the paint flow and mix better during the stirring process, reduce the situation of uneven stirring in some areas, further improve the uniformity of paint stirring, and ensure that the paint concentration is consistent.

[0036] Specifically, such as Figure 5 As shown, the bottom of the bottom stirring rod 25 is fixedly connected to the stirring column 8, which is located on the bottom side inside the coating cylinder 21.

[0037] Specifically, such as Figure 4 As shown, a filter 9 is embedded in the front side of the inside of the straw 41. The filter 9 is in the shape of a mesh.

[0038] In this embodiment: by setting the stirring column 8 and the filter screen 9, inside the paint cylinder 21, the stirring column 8 at the bottom of the bottom stirring rod 25 will rotate together with the stirring rod 25. Since it is located on the bottom side inside the paint cylinder 21, it can effectively stir the paint that is easy to settle at the bottom, prevent the paint from clumping and settling at the bottom, and make the paint in the entire paint cylinder 21 fully mixed. In addition, the mesh filter screen 9 on the front side inside the suction tube 41 can filter the paint when the paint is sucked into the suction tube 41, intercepting impurities and possible clumps in the paint, preventing these impurities from entering the spray pump 42 and the subsequent spraying system, ensuring smooth spraying and coating quality.

[0039] Working Principle: During the process of spraying polymer coatings onto metal components, the metal components to be coated are first placed on the placement mesh 28. At this time, the motor 22 is turned on, and the output shaft of the motor 22 drives the shaft 23 to rotate. The connecting sleeve 24 and stirring rod 25 on the shaft 23 rotate accordingly, stirring the polymer coating in the coating cylinder 21. The circular diversion hole 7 on the outer side of the stirring rod 25 allows the coating to flow and mix better. The stirring column 8 at the bottom of the bottom stirring rod 25 also rotates, effectively stirring the coating at the bottom of the coating cylinder 21, preventing sedimentation and clumping, and ensuring uniform coating concentration. Next, the spraying pump 42 is started. The spraying pump 42 draws coating from the coating cylinder 21 through the suction pipe 41. The mesh filter 9 inside the suction pipe 41 filters the coating, intercepting impurities and clumps, ensuring the purity of the coating entering the spraying system. The drawn-out coating is then pumped by the spraying pump 42. After pressurization, the coating is delivered to the spraying plate 44 through the output pipe 43. The coating is then evenly sprayed onto the metal component placed on top of the placement net 28 by the uniform spraying heads 45 evenly distributed at the bottom of the spraying plate 44. During the spraying process, the supplementary lights 6 at the bottom of the suspension rods 5 on both sides of the top inside the support plate 3 provide sufficient light, making it convenient for operators to observe the spraying status of the metal component and promptly detect and deal with any uneven spraying problems. Excess coating will drip down and, after being filtered and purified by the filter and purification net 27, will flow back into the coating cylinder 21 through the discharge hopper 26, realizing the recycling and reuse of the coating. After one side of the metal component is sprayed, the operator uses a tool to flip it over and spray it again to ensure that the surface of the metal component is evenly covered by the polymer coating, ultimately improving the uniformity and stability of the coating and enhancing the performance and service life of the metal component.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
