Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a surface coating equipment for aluminum sheet processing. Background Technology

[0002] Aluminum sheets, as a lightweight, high-strength, and corrosion-resistant metal material, are widely used in building curtain walls, rail transportation (such as high-speed rail carriages), home appliance housings (such as refrigerator and air conditioner panels), and automotive parts (such as body panels). Their surface properties directly affect the decorative properties, weather resistance, and service life of the end products. For example, aluminum sheets for buildings need to be coated with an anti-oxidation and anti-UV protective coating. Coating of home appliance housings can improve the appearance and scratch resistance. Coating of automotive aluminum sheets needs to balance aesthetics and corrosion resistance. Therefore, the surface coating process is a key step in the aluminum sheet processing to enhance the added value and functionality of the product.

[0003] Traditional spraying equipment often uses a method of laying aluminum plates flat (horizontal conveying), requiring spraying both sides sequentially with a single-sided spray gun, or achieving double-sided spraying through a flipping mechanism. Single-sided spraying requires two positioning operations, which is time-consuming. Flipping spraying is prone to positioning errors due to the shift in the center of gravity of the aluminum plate, and the flipping process may scratch the surface. In addition, dust, metal shavings, and other impurities easily adhere to the surface of the aluminum plate during cutting and transportation. Existing aluminum plates are not cleaned before spraying, which can lead to defects such as "particle spots" and "bumps" in the coating after spraying. Utility Model Content

[0004] The purpose of this invention is to provide a surface coating equipment for aluminum plate processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A surface coating device for aluminum plate processing includes a lower roller conveyor and an upper roller conveyor. A support plate is mounted on the lower roller conveyor, and an electric telescopic rod is mounted on the support plate. The electric telescopic rod is fixedly connected to connecting seats mounted on both sides of the upper roller conveyor. Aluminum plate auxiliary conveying structures are installed in the middle of the rollers of both the lower and upper roller conveyors. V-grooves are formed on the surface of the aluminum plate auxiliary conveying structures. A coating hood is mounted on the lower roller conveyor, with inlet and outlet ports on both sides of the coating hood. The upper roller conveyor passes through the inlet and outlet ports on both sides of the coating hood. Roller frames are symmetrically mounted on the conveying head of the lower roller conveyor, and brush rollers are rotatably mounted inside the roller frames. A motor directly connected to the roller shaft of the brush rollers is mounted on the top of the roller frames.

[0006] As a further embodiment of this utility model: a partition plate is provided inside the spraying hood, which divides the inside of the spraying hood into two parts, the front and rear parts being a spraying chamber and a drying chamber, respectively. Spraying racks are installed on the inner walls of both sides of the spraying chamber, and paint delivery pipes are connected to the spraying racks. Dryers are installed on both sides of the drying chamber.

[0007] As a further improvement of this utility model, a viewing window is installed on one side of the drying chamber.

[0008] As a further improvement of this invention, an exhaust port is installed on the top of the drying chamber.

[0009] As a further embodiment of this utility model: a paint receiving trough is installed inside the lower roller conveyor facing the spraying chamber, the paint receiving trough is connected to a discharge pipe, and a control valve is installed on the discharge pipe.

[0010] As a further improvement of this utility model, the distance between the two support plates is equal to the width of the inlet and outlet.

[0011] As a further improvement of this invention, the dryers located on both sides of the spray coating hood are staggered.

[0012] As a further improvement of this utility model, the partition plate has an opening in the middle to facilitate the passage of the upper roller conveyor and the aluminum plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves stable transmission of aluminum plates in a vertical position by setting an auxiliary conveying structure with a V-shaped surface between the upper and lower roller conveyors and an electrically adjustable spacing design. This facilitates simultaneous double-sided spraying of the aluminum plates. Compared with the existing method of placing the aluminum plates flat on the conveyor and only spraying one side, this utility model eliminates the need for secondary flipping and spraying, resulting in higher spraying efficiency.

[0014] 2. This utility model achieves pretreatment of dust on the surface of aluminum plates by setting a double brush roller cleaning structure at the head end of the upper and lower roller conveyor, thus avoiding excessive dust and debris adhering to the surface of aluminum plates and reducing the coating quality.

[0019] 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.

[0020] Please see Figure 1-3 In this embodiment of the present invention, a surface spraying device for aluminum plate processing includes a lower roller conveyor 1 and an upper roller conveyor 2. A support plate 3 is installed on the lower roller conveyor 1, and an electric telescopic rod 4 is installed on the support plate 3. The electric telescopic rod 4 is fixedly connected to the connecting seats 5 installed on both sides of the upper roller conveyor 2. An aluminum plate auxiliary conveying structure 15 is installed in the middle of the roller body of the lower roller conveyor 1 and the middle of the roller body of the upper roller conveyor 2. A V-shaped groove 16 is opened on the surface of the aluminum plate auxiliary conveying structure 15, which can limit the aluminum plate. A spraying cover 6 is installed on the lower roller conveyor 1, and inlet and outlet ports 20 are opened on both sides of the spraying cover 6. The upper roller conveyor 2 passes through the inlet and outlet ports 20 on both sides of the spraying cover 6. The spraying hood 6 is equipped with a partition plate 7, which divides the spraying hood 6 into two parts: a spraying chamber 8 and a drying chamber 9. Spraying racks 10 are installed on the inner walls of both sides of the spraying chamber 8, and paint delivery pipes 11 are connected to the outside of the spraying racks 10. Dryers 12 are installed on both sides of the drying chamber 9. The spraying hood 6 can spray and dry the aluminum plate, so that the aluminum plate can be sprayed quickly and the spraying efficiency can be improved.

[0021] A viewing window 13 is installed on one side of the drying chamber 9. The viewing window 13 allows personnel to easily observe the drying process inside the drying chamber from outside the equipment, so as to better determine whether the aluminum plate has been dried.

[0022] The top of the drying chamber 9 is equipped with an exhaust port 14, which can be connected to an external exhaust gas purification device to extract most of the paint exhaust gas in the spray hood 6 for purification before discharge, thereby reducing the impact on the surrounding air environment during spraying.

[0023] Inside the lower roller conveyor 1, facing upwards directly towards the spraying chamber 8, there is a paint receiving tank 23. The paint receiving tank 23 is connected to a discharge pipe 21. A control valve 22 is installed on the discharge pipe 21. The paint receiving tank 23 is used to receive excess paint during spraying and collect the excess paint and discharge it through the discharge pipe 21 at regular intervals for reuse, thereby reducing paint waste.

[0024] The spacing between the two support plates 3 is equal to the width of the inlet / outlet 20. This design ensures that the width of the inlet / outlet 20 meets the requirements for the passage of aluminum plates on the lower roller conveyor 1.

[0025] The dryers 12 located on both sides of the spray hood 6 are staggered. The staggered distribution can prevent the hot air blown out from both sides from forming convection and increasing energy consumption.

[0026] The partition plate 7 has an opening in the middle to facilitate the passage of the upper roller conveyor 2 and the aluminum plate. This design is to ensure that the aluminum plate can pass through the spraying chamber 8 and the drying chamber 9 without obstruction.

[0027] Please see Figure 1 The lower roller conveyor 1 has roller frames 17 symmetrically installed at the conveying head end. Brush rollers 18 are rotatably installed inside the roller frames 17. A motor 19 directly connected to the roller shaft of the brush rollers 18 is installed on the top of the roller frames 17. The two brush rollers 18 form a double brush roller cleaning structure, which realizes the pretreatment of dust on the surface of the aluminum plate and avoids excessive dust and debris adhering to the surface of the aluminum plate, thus reducing the coating quality.

[0028] The working principle of this utility model is as follows: In use, the height of the upper roller conveyor 2 is first adjusted by starting the electric telescopic rod 4 according to the height of the aluminum plate. After adjustment, the lower roller conveyor 1 and the upper roller conveyor 2 are started. The lower roller conveyor 1 and the upper roller conveyor 2 drive the upper and lower aluminum plate auxiliary conveying structure 15 to rotate. The aluminum plate is inserted between the upper and lower aluminum plate auxiliary conveying structure 15 and is conveyed forward under the drive of the upper and lower aluminum plate auxiliary conveying structure 15. When the conveying starts, the motor 19 will drive the brush roller 18 to rotate and sweep the two sides of the aluminum plate to achieve pre-cleaning. When the aluminum plate enters the spraying hood 6, the paint enters the spraying frame 10 under the suction of the external paint pump, and then sprays out from the different spray holes opened on the spraying frame 10 to achieve double-sided spraying of the aluminum plate. After the spraying is completed, it enters the drying chamber 9. The dryers 12 located on both sides of the drying chamber 9 will quickly dry the paint on both sides of the aluminum plate. After drying, it is conveyed out from the spraying hood 6.

[0029] Although the present invention 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 invention should be included within the protection scope of the present invention.
