Description

Technical Field

[0001] This utility model relates to the field of aluminum plate processing technology, and in particular to a device for uniformly spraying coating on the surface of aluminum plates. Background Technology

[0002] In modern industrial production, aluminum sheets are widely used in many fields such as construction, automobiles, aerospace, and electronics due to their numerous advantages, including light weight, high strength, and good thermal and electrical conductivity. In the construction industry, aluminum sheets are used for curtain walls, roofs, and other components, which are not only aesthetically pleasing but also durable. In the automotive industry, aluminum sheets are used in body manufacturing to reduce the overall vehicle weight, thereby reducing energy consumption. However, aluminum sheets are easily corroded when directly exposed to air, and their surface aesthetics and certain special properties require various coatings to meet different usage needs. With the scaling up of industrial production and the continuous improvement of product quality requirements, the quality requirements for aluminum sheet surface coatings are becoming increasingly stringent, especially the uniformity of the coating, which directly affects the performance and appearance of the aluminum sheet.

[0003] The structure of a uniform coating spraying device for aluminum plates includes a conveying mechanism, a spraying chamber, a spray gun system, a paint supply system, a pressure pump, and a conveying pipeline. However, under traditional manual spraying and unstable mechanical conveying methods, the moving speed of the aluminum plate is not constant, which can cause paint to accumulate in some areas while the thickness is insufficient in other areas. In existing technologies, aluminum plates are transported at a uniform speed by a conveyor belt, which can precisely control the residence time and moving speed of the aluminum plate in the spraying area and ensure that the paint sprayed by the spray gun forms a uniform thickness on the surface of the aluminum plate. However, if the paint is not mixed evenly, the components of pigments, solvents, and additives will be unevenly distributed, which can lead to inconsistent color, uneven gloss, and even incomplete curing of the aluminum plate surface during spraying.

A U-shaped frame 8 is fixedly connected to the top left side of the base plate 1, and a liquid storage tank 9 is fixedly connected to the top of the U-shaped frame 8 for convenient storage of the spraying liquid. The storage tank 9 is fixedly connected to the top center of a support frame 10. The top front side of the storage tank 9 is fixedly connected to a support block 11. The top of the support block 11 is fixedly connected to a motor 12. The output end of the motor 12 passes through the support frame 10 and is fixedly connected to a bevel gear 13.

The top of the base plate 1 is equipped with a drying mechanism 2, which is used to heat the coating on the surface of the aluminum plate.

[0032] Specifically, the conveyor belt 5 can smoothly transport the aluminum plate from one end to the other, ensuring the continuity of the coating process.

[0033] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5 The drying mechanism 2 includes a drying chamber 201. The bottom of the drying chamber 201 is fixedly connected to the top right side of the base plate 1. An air inlet duct 202 is connected to the top middle of the front side of the drying chamber 201.

A protective coating 207 is fixedly connected to the bottom outer wall of the sealing curtain 206 to prevent damage to the aluminum plate.

[0034] Specifically, the air inlet duct 202 not only ensures the entry of air, but also distributes hot air evenly into the drying chamber 201 through multiple air outlets 203 connected at its bottom. The heating element 204 can quickly raise the air temperature to meet the drying requirements. The fan 205 draws in external cold air and pushes hot air through the air outlets 203, thereby realizing the circulation of air in the drying chamber 201. In order to prevent the leakage of moisture and heat during the drying process, sealing curtains 206 are rotatably installed on both the left and right sides of the drying chamber 201, which can be tightly attached to the opening of the drying chamber 201 to effectively maintain the stability of the internal environment. The bottom outer wall of the sealing curtain 206 is also fixedly connected with a protective coating 207 to prevent damage to the surface coating of the aluminum plate during transportation.

[0035] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4An observation window 19 is fixedly connected to the front of the liquid storage tank 9, and a scale plate 20 is fixedly connected to the right side of the observation window 19 for easy reading of the liquid level.

A controller 21 is fixedly connected to the front of the U-shaped frame 8. The controller 21 is convenient to be electrically connected to the motor 7, the motor 12 and the fan 205 for easy control of the equipment.

[0036] Specifically, the observation window 19 allows for easy viewing of the storage conditions inside the liquid storage tank 9, the scale lines on the scale plate 20 allow for accurate reading of liquid level data, the breathing light 26 can indicate the equipment's operating status based on its flashing pattern, and the controller 21 is electrically connected to motor 7, motor 12 and fan 205, making it easy to set parameters and monitor them.

[0037] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 The bottom of the base plate 1 is fixedly connected with an anti-slip pad 17. The front top of the U-shaped frame 8 is fixedly connected with a nameplate 18 for easy understanding of the equipment. The front and rear sides of the base plate 1 are both fixedly connected with baffles 22. The top rear side of the liquid storage tank 9 is connected to a feed inlet 23 for easy addition of spraying liquid. The top of the feed inlet 23 is engaged with a feed pipe 24. The outer wall of the feed pipe 24 is fixedly connected with a handle 25.

[0038] Specifically, the anti-slip pad 17 ensures that the equipment remains stable on various surfaces, the nameplate 18 is marked with necessary information and markings for easy identification and operation, the baffle 22 not only enhances the overall structural stability of the equipment, but also effectively prevents the aluminum plate from slipping and ensures the stability of the aluminum plate, the feed pipe 24 facilitates the entry of the spraying liquid, and a handle 25 for easy gripping is fixedly connected to the outer wall of the feed pipe 24, making the operation process more convenient.

[0039] Working principle: The conveyor belt 5 is driven by motor 7, which rotates the aluminum plate at a constant speed. When the aluminum plate reaches the bottom of the U-shaped frame 8, motor 12 at the top of the liquid storage tank 9 drives bevel gear 13 to rotate. Bevel gear 13 drives bevel gear 14 to rotate, which in turn drives agitator 15. This continuously stirs the spraying liquid inside the liquid storage tank 9. The liquid is then sprayed onto the aluminum plate at the top of the conveyor belt 5 via spray gun 16. The stirring of the spraying liquid by agitator 15 ensures the uniformity of the coating, allowing the coating to be fully utilized during the spraying process. This prevents clogging and avoids poor local spraying results and paint waste due to uneven composition. The conveyor belt 5 allows the aluminum plate to be transported at a constant speed, ensuring that the position and speed of the aluminum plate are controllable throughout the spraying process. This helps subsequent spraying operations to be carried out according to predetermined parameters. The uniform speed allows the spraying time and distance interval of the spray gun 16 on the aluminum plate to be relatively fixed, thus ensuring the uniformity of the coating thickness and coverage.

[0040] After being sprayed, the aluminum plate passes through the sealing curtain 206 and enters the inside of the fan 205. The bottom protective coating 207 of the sealing curtain 206 can form an isolation layer between the sealing curtain 206 and the aluminum plate, preventing the sealing curtain 206 from directly contacting the coating of the aluminum plate. The fan 205 blows air over the heating element 204, heating the air into hot air. The hot air is blown onto the surface of the aluminum plate through the air inlet duct 202 and the air outlet 203, where it undergoes convective heat exchange with the coating on the surface of the aluminum plate, transferring heat to the coating. This makes the temperature distribution in the drying chamber 201 more uniform, allowing the coating on the surface of the aluminum plate to dry in a more stable temperature environment, avoiding problems such as local overheating and excessive temperature gradients, and helping to ensure the consistency of coating quality.

[0041] 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.
