Description

Technical Field

[0002] Polymer coatings possess excellent corrosion resistance, wear resistance, and insulation properties, providing good protection for metal components. In the traditional process of applying polymer coatings to metal components, manual spraying or simple mechanical spraying methods are often used. Manual spraying is labor-intensive, has low production efficiency, and the spraying quality is greatly affected by the operator's skill level and working conditions, making it difficult to ensure the uniformity and consistency of the coating. This results in unstable coating quality, which cannot meet the needs of high-quality, large-scale production.

[0003] To address the aforementioned issues, existing patents offer solutions. The existing spraying structures lack a structure for repeatedly spraying the surface of metal components. This makes it difficult to improve the performance of some polymer coatings with special performance requirements, such as high wear resistance and high corrosion resistance coatings, through multiple layers of spraying. Consequently, metal components are prone to coating peeling and premature wear during actual use.

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

[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 reciprocating spraying structure for polymer coating of metal components includes a storage tank 1, a spraying mechanism 2 fixedly connected to the top of the inner side of the storage tank 1, a circulation mechanism 3 fixedly connected to the rear side of the spraying mechanism 2, support blocks 4 fixedly connected to both sides of the inner side of the storage tank 1, and a limit plate 5 slidably connected to the top of the support blocks 4.

[0027] The spraying mechanism 2 includes a support beam 21, a chute 22, a slider 23, a lead screw 24, a servo motor 25, a connecting block 26, a nozzle 27, and a microcontroller 28. The support beam 21 is fixedly connected to the top of the inner side of the storage box 1. The chute 22 is opened on the inner side of the support beam 21. The lead screw 24 is rotatably connected to the inner side of the chute 22. The slider 23 is threadedly connected to the surface of the lead screw 24. The servo motor 25 is fixedly connected to the top of the left side of the storage box 1. The connecting block 26 is fixedly connected to the bottom of the slider 23. The nozzle 27 is fixedly connected to the bottom of the connecting block 26. The microcontroller 28 is fixedly connected to the left side of the storage box 1.

[0028] In this embodiment: A storage bin 1 is provided to store polymer coatings, ensuring a sufficient supply of coatings for the spraying process and guaranteeing smooth operation. It also supports and limits the spraying mechanism 2, the circulation mechanism 3, and the support block 4. The support block 4 supports the limiting plate 5, allowing it to slide stably on top. The limiting plate 5 limits and positions the metal components. The support beam 21 supports and limits the slide groove 22, the lead screw 24, and the slider 23. The slide groove 22 provides space for the slider 23 to slide and move, constraining its trajectory and ensuring stable linear movement. The slider 23 converts the rotational motion of the lead screw 24 into free motion. The linear reciprocating motion of the body drives the connecting block 26 and the nozzle 27 to reciprocate horizontally. The lead screw 24 rotates under the drive of the servo motor 25. The servo motor 25 provides power for the rotation of the lead screw 24. Through speed control and direction control, the reciprocating motion of the slider 23 can be realized. The connecting block 26 connects the slider 23 and the nozzle 27, transmitting the motion of the slider 23 to the nozzle 27. The nozzle 27 sprays the paint evenly onto the surface of the metal component. Through linkage with the slider 23, the reciprocating spraying of the metal component is realized. The microcontroller 28 controls the servo motor 25 and can set and adjust various parameters in the spraying process, such as spraying speed, spraying stroke, and spraying time.

[0029] Specifically, such as Figure 4 As shown, the circulation mechanism 3 includes a circulation pump 31, a material extraction pipe 32, and a material conveying hose 33. The circulation pump 31 is fixedly connected to the rear side of the storage tank 1.

[0030] Specifically, such as Figure 4 As shown, the extraction pipe 32 is fixedly connected to the bottom of the circulating pump 31, and the bottom of the extraction pipe 32 passes through the storage tank 1 and is fixedly connected to the inside of the storage tank 1.

[0031] Specifically, such as Figure 4 As shown, the conveying hose 33 is fixedly connected to the top of the circulating pump 31, and the top of the conveying hose 33 passes through the storage tank 1 and is fixedly connected to the rear side of the connecting block 26.

[0032] In this embodiment: By setting a circulation pump 31 to provide power for the circulation of paint, the paint can be drawn from the bottom of the storage tank 1 and delivered to the nozzle 27, ensuring a continuous supply of paint. The extraction pipe 32 can draw the paint from the bottom of the storage tank 1, and the delivery hose 33 delivers the paint drawn by the circulation pump 31 to the nozzle 27, providing a continuous supply of paint to the nozzle 27. Its flexible characteristics allow the connecting block 26 to maintain stable paint delivery during reciprocating motion, avoiding connection problems caused by movement that may affect the spraying process, and ensuring the continuity of the spraying process.

[0033] Specifically, such as Figure 5 As shown, material leakage holes 6 are provided on both sides of the inner side of the limiting plate 5, and a dust filter 7 is fixedly connected to the inner side of the material leakage holes 6.

[0034] Specifically, such as Figure 5 As shown, a handle 8 is fixedly connected to the front side of the limiting plate 5, and the surface of the handle 8 is engraved with anti-slip texture.

[0035] In this embodiment: by setting the discharge hole 6, excess paint during the spraying process can flow back to the storage tank 1 through the discharge hole 6, avoiding paint accumulation on the limiting plate 5, which helps to keep the spraying work area clean, while improving paint utilization and reducing waste. By setting the dust filter 7, external dust and other impurities can be effectively prevented from entering the storage tank 1 through the discharge hole 6, avoiding dust from mixing into the paint and affecting the coating quality, ensuring the purity of the paint, and thus ensuring the quality of the polymer coating of the metal components. By setting the handle 8, it is convenient for the operator to manually move the limiting plate 5. By setting the anti-slip texture, the friction between the operator's hand and the handle 8 can be increased, making the operator more stable when holding the handle 8 to move the limiting plate 5.

[0036] Specifically, such as Figure 5 As shown, a filling pipe 9 is fixedly connected to the left side of the storage box 1, and a cap 10 is snapped onto the top of the filling pipe 9.

[0037] Specifically, such as Figure 4 As shown, a reinforcing seat 11 is fixedly connected to the front side of the circulating pump 31, and the side of the reinforcing seat 11 away from the circulating pump 31 is fixedly connected to the rear side of the storage tank 1.

[0038] In this embodiment: by setting the filling pipe 9, a dedicated channel is provided for adding paint to the storage tank 1, making the paint adding process more convenient. By setting the cap 10, dust, debris and other contaminants can be effectively prevented from entering the storage tank 1 when no paint is being added, thus avoiding contamination of the paint. By setting the reinforcing seat 11, the stability of the circulation pump 31 during operation is enhanced, the vibration generated by the operation of the circulation pump 31 is reduced, the loosening or damage of components caused by vibration is avoided, and the service life of the circulation pump 31 is extended.

[0039] Working principle: First, the user moves the storage tank 1 to the desired working position. Then, the user pulls out the limiting plate 5 using the handle 8 and places the metal component to be coated on the surface of the limiting plate 5. Next, the user opens the cover 10 and adds polymer coating to the bottom inside the storage tank 1 through the filling pipe 9. After the coating is added, the user closes the cover 10 and the filling pipe 9. Then, the user powers on and starts the circulation pump 31. The circulation pump 31 draws the coating through the extraction pipe 32 and pressurizes it to deliver it to the conveying hose 33. At this time, the user powers on and starts the microcontroller 28. The microcontroller 28 then... The program controls the servo motor 25 to rotate. When the servo motor 25 rotates, it drives the lead screw 24 to rotate. The lead screw 24 causes the slider 23 to move back and forth along the slide groove 22. When the slider 23 moves, it drives the connecting block 26 to move synchronously. The connecting block 26 drives the nozzle 27 to move synchronously. The nozzle 27 sprays the paint conveyed by the material conveying hose 33 onto the surface of the metal component. After the paint is sprayed, the excess paint will fall back into the bottom of the storage box 1 through the leakage hole 6. Finally, the user can pull out the limit plate 5 again through the handle 8 to take out the metal component and send it to the next process.

[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.
