Description

Technical Field

[0001] The invention relates to the field of aluminum veneer coating, in particular to a coating process and paint spraying equipment on the surface of an aluminum veneer. Background Art

[0002] Aluminum veneers are mainly based on aluminum alloy plates. Commonly used aluminum alloy materials include AA1100 pure aluminum plate, AA3003 alloy aluminum plate, etc. These aluminum alloy materials have the characteristics of low density, high strength, and corrosion resistance, providing good basic performance for aluminum veneers. In actual production, some other elements will be added or alloying treatment will be performed as needed to further improve the performance of the material, such as improving hardness and toughness.

[0003] The processing of aluminum veneer generally includes three processes: plate cutting, forming and surface treatment. Surface treatment is the key link in the processing of aluminum veneer. Common surface treatment processes include fluorocarbon spraying, polyester spraying, anodizing, powder spraying, etc. Take fluorocarbon spraying as an example, it is to evenly apply the coating containing fluorocarbon resin on the surface of the aluminum plate by electrostatic spraying, and then cure it by high temperature baking to form a strong, durable, weather-resistant and decorative coating.

[0004] At present, the spray heads for spraying aluminum veneers are all fixedly set, and they can only move vertically up and down with the driving parts to realize reciprocating spraying, but the angle of the spray heads cannot be adjusted during the spraying process. As the shapes and structures of aluminum veneers are different, during the specific spraying, the aluminum veneers are easy to cause some dead corners due to their own shapes and structures, so the spray heads need to spray reciprocatingly many times, and the reciprocating spraying easily causes the coating of other drives to be too thick, and the dead corner area is sprayed thinner, resulting in uneven spraying and reducing the quality of the spraying. Therefore, a surface coating process and spraying equipment for aluminum veneers are proposed. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention proposes an aluminum veneer surface coating process and paint spraying equipment, which can adjust the nozzle at multiple angles when spraying the aluminum veneer, avoiding the generation of painting dead corners due to the shape and structure of the aluminum veneer during painting, thereby improving the uniformity of painting and the quality of the final coating.

The technical solution of the present invention can also drive the slide seat 2 to slide on the guide rod through the contact between the trapezoidal block and the limit plate when the horizontal plate conflicts with the vertical plate to drive the nozzle to deflect up and down, thereby realizing that when the horizontal plate moves up and drives the nozzle to deflect upward, the contact between the trapezoidal block on the front side and the limit plate drives the rack to move backward, so that the nozzle can also deflect backward, and when the horizontal plate moves down and drives the nozzle to deflect downward, the contact between the trapezoidal block on the rear side and the limit plate drives the rack to move backward, so that the nozzle can also deflect forward, thereby increasing the deflection angle of the nozzle, further improving the nozzle's dead angle spraying of the aluminum single plate, and improving the quality of the subsequent coating; 3. The technical solution of the present invention can also drive the swing plate and the shaking plate to act on the toggle plate through the upward movement of the slide seat, so that the hook shakes, thereby preventing the aluminum veneer from being stably suspended thereon, and blocking the area near the hook hanging point of the aluminum veneer when spraying paint, thereby improving the uniformity of spraying paint on the hanging area.

An angle adjustment component is provided on the bracket 1, and the angle adjustment component is used to adjust the paint spraying angle of the nozzle 15 when the slide seat 6 slides. A swing plate 29 is rotatably connected to the top of the slide rail 2 through a spring hinge, and a shaking plate 30 is connected to the swing plate 29 for pushing and shaking the hook 4. A linkage component is provided on the slide seat 6, and the linkage component is used to resist and rotate the shaking plate 30 when the slide seat 6 moves up.

[0022] Embodiment 2: like Figure 1-7 As shown, the present invention discloses a surface coating process and painting equipment for an aluminum single plate. Compared with the second embodiment, this embodiment discloses the structure of an angle adjustment component.

[0023] The angle adjustment assembly includes a gear 16, a guide rod 17, a slide seat 18, a spring 19, a slide frame 20, a trapezoidal block 22, and a limit plate 23. The gear 16 is sleeved on the nozzle 15 and is located at the rotation axis of the nozzle 15 relative to the mounting frame 13. The guide rod 17 is connected to one side of the mounting frame 13. The slide seat 18 is slidably sleeved on the outer side of the guide rod 17 and slides in contact with the side of the mounting frame 13. The spring 19 sleeved on the outer side of the guide rod 17 is connected between the two sides of the slide seat 18 and the mounting frame 13. The slide frame 20 is connected to the upper and lower sides of the slide seat 18. A rack 21 meshing with the gear 16 is embedded on the slide frame 20. The trapezoidal block 22 is connected to both ends of the slide frame 20. A limit plate 23 that slides against the trapezoidal block 22 is connected to the top of the slide seat 16 on one side, and a limit plate 23 that slides against the trapezoidal block 22 is connected to the bottom of the slide seat 16 on the other side.

[0024] The rotating sleeves passing through both ends of the mounting frame 13 are equipped with a rotating shaft 14, the nozzle 15 is installed on the surface of the rotating shaft 14 in the mounting frame 13, the gear 16 is connected to the extended ends of the rotating shaft 14 on the upper and lower sides of the mounting frame 13, and the two ends of the sliding frame 20 extend to the two outer sides of the mounting frame 13. The sliding frame 20 has an extension on the two outer sides of the mounting frame 13 to enable the slide seat 2 18 and the sliding frame 20 to have a sliding space for moving forward and backward displacement.

[0025] like Figure 3 and 4 As shown, when the driving assembly acts on the vertical plate 24 to make it slide, the slide rail 2 first drives the slide seat 6 to move to the highest point or the lowest point, so that the turntable 8, the connecting plate 9 and the horizontal plate 10 move accordingly, and then drives the vertical plate 24 to move to the position directly below the horizontal plate 10 at the highest point, or directly above the horizontal plate 10 at the lowest point; Take the slide 6 moving to the lowest position as an example: After adjusting the position of the vertical plate 24, the control rail 2 drives the slide seat 16 to move upward, and the horizontal plate 10 will conflict with the lower end of the vertical plate 24, so that the horizontal plate 10 deflects and slides with the surface of the vertical plate 24. In the process, the nozzle 15 in the installation frame 13 will be deflected upward until it slides to the other end of the vertical plate 24, and then it is reset to a horizontal equilibrium state under the action of the spring 12. When the horizontal plate 10 is driven downward again, the horizontal plate 10 will conflict with the upper end of the vertical plate 24, and drive the nozzle 15 in the installation frame 13 to deflect downward, so as to adjust the up and down deflection of the nozzle 15 for spraying paint; At the same time, when the nozzle 15 is driven to deflect upward, the trapezoidal block 22 connected to the front side of the slide frame 20 will conflict with the limit plate 23 connected to the top of the front slide seat 6, pushing the slide frame 20 and the rack 21 to move backward, thereby driving the nozzle 15 deflected upward to deflect forward synchronously. Similarly, when the nozzle 15 is driven to deflect downward, the trapezoidal block 22 connected to the rear side of the slide frame 20 will conflict with the limit plate 23 connected to the rear side under the slide seat 6, pushing the slide frame 20 and the rack 21 to move forward, thereby driving the nozzle 15 deflected downward to deflect backward synchronously. In this way, when spraying aluminum panels with special shapes and structures and forming dead corners for painting, the nozzle 15 can be adjusted to spray paint at multiple angles by adjusting the vertical plate 24, thus overcoming the problems of being unable to spray paint in dead corners and uneven painting, and improving the quality of the formed coating.

[0026] The same solution applies to the sliding seat 6 moving to the highest point before the vertical plate 24 is adjusted, which will not be described in detail.

[0027] Embodiment three: like Figure 1-10As shown, the present invention discloses an aluminum single plate surface coating process and a painting device. Compared with the second embodiment, this embodiment discloses the structure of a linkage component.

[0028] The linkage assembly includes an inclined plate 28, an inclined block 31, a baffle 32, and a toggle plate 35. The inclined plate 28 is connected to the slide seat 6, the inclined block 31 is connected to the swing plate 29 and slides in contact with the inclined surface of the inclined plate 28, the baffle 32 is connected to the upper end of the slide rail 2, and is limited by the swing plate 29, the toggle plate 35 is connected to the side of the hook 4 close to the swing plate 29, the shaking plate 30 is above the toggle plate 35, and is in contact with the upper end surface of the toggle plate 35, the inclined block 31 and the baffle 32 are on the side of the swing plate 29 away from the hook 4 On one side, such a configuration can cause the inclined plate 28 to collide with the inclined block 31 when the slide 6 is driven upward, driving the swing plate 29 and the shaking plate 30 to rotate toward the side away from the baffle 32 and close to the toggle plate 35, generating a force on the toggle plate 35, so that the hook 4 can shake, and then the aluminum single plate suspended thereon shakes, thereby avoiding the relatively stable suspension between the hook 4 and the aluminum single plate, causing obstruction to the hanging place of the aluminum single plate hook 4, and making it impossible to spray paint, thereby further improving the uniformity and comprehensiveness of the paint spraying.

[0029] A guide rail seat 33 is slidably connected inside the guide rail 3, and an electric reel 34 is rotatably connected to the lower end of the guide rail seat 33. A pull rope 36 is wound on the electric reel 34, and the hook 4 is connected to the pull rope 36. The toggle plate 35 is connected to the electric reel 34. The rotatable connection between the electric reel 34 and the guide rail seat 33 is conducive to the toggle plate 35 causing the hook 4 to shake. The arrangement of the electric reel 34 and the pull rope 36 makes it convenient to drop and remove the painted aluminum panel hung at a high place.

[0030] A cavity 37 is provided in the hook 4, and two threaded holes 38 are provided on the surface of the cavity 37 and the hook 4. A stud 39 is threadedly connected to the inner wall of one threaded hole 38, and an elastic rope 40 is connected between the stud 39 and the inner wall of the cavity 37. Due to the different shapes and structures of aluminum veneers, different hanging methods are used during specific painting. Some can be directly hung on the hook 4, while others need to be tied with a rope in advance and then hung on the hook 4. In this way, an elastic rope 40 that can be stored or pulled out is provided on the hook 4, and can be stably installed in the threaded hole 38 on the hook 4 through the stud 39, which facilitates the painting method of tying the aluminum veneer.

[0031] Embodiment 4: like Figure 3 As shown, the present invention discloses an aluminum single plate surface coating process and a painting device. Compared with the third embodiment, this embodiment discloses the structure of a driving component.

[0032] The driving assembly includes a two-way telescopic member 25 and an articulated seat 26. The two-way telescopic member 25 is installed on the bracket 1. The articulated seat 26 is connected to the telescopic ends on both sides of the two-way telescopic member 25. A rotating plate 27 is rotatably connected between each articulated seat 26 and the vertical plate 24. The two-way telescopic member 25 drives the rotating plate 27 to rotate to drive the vertical plate 24, which facilitates the control of the moving distance of the vertical plate 24. This is because the angle deflection amplitude of the nozzle 15 can be adjusted by adjusting the position of the vertical plate 24 directly above or below the horizontal plate 10.

[0033] The sliding seats 6 on both sides are connected to the sides away from each other with sliders 5, the sliders 5 are slidably connected in the slide rails 2, and the bracket 1 is also connected to a slide rod 7. The sliding seat 6 is slidably sleeved on the outer side of the slide rod 7. The setting of the slider 5 and the slide rod 7 facilitates the stability of the sliding seat 6 and the device thereon during movement.

[0034] Embodiment five: like Figure 1-10 As shown, the present invention discloses a surface coating process for an aluminum single plate, comprising the following steps: Step 1: First, according to the shape and structure of the aluminum veneer to be sprayed, the aluminum veneer is reasonably hung on the hook 4, and the guide rail 3 is controlled to drive the hook 4 and the aluminum veneer hung thereon to slide intermittently; Step 2: When the aluminum veneer passes through the nozzle 15 and faces the nozzle 15, the guide rail 3 is controlled to stop running, and then the slide rail 2 is started to drive the slide seat 6 to slide up and down to spray one side of the aluminum veneer; Step 3: When the aluminum veneer cannot be effectively painted at some positions due to its shape and structure, first control the slide rail 2 to drive the slide seat 6 to move to the top or bottom, start the drive assembly to control the vertical plate 24 to slide toward the horizontal plate 10, until the vertical plate 24 is directly above the horizontal plate 10 or the vertical plate 24 coincides with the path of the horizontal plate 10 sliding up and down; Step 4: Start the slide rail 2 again to drive the slide seat 6 to slide up and down. At this time, the horizontal plate 10 located directly above or directly above the vertical plate 24 will contact with one end of the vertical plate 24 and rotate. During this process, the turntable 8, the connecting plate 9 and the nozzle 15 installed in the installation frame 13 will be driven to spray with the angle adjusted up and down; Step 5: When the connecting plate 9 rotates, the adjusting component will drive the adjusting nozzle 15 to rotate in the front-to-back direction, so as to realize the tilted spraying in both up and down directions and the tilted spraying in the front and back directions; Step six: When the slide seat 6 slides to the height of the slide rail 2, it can cooperate with the linkage assembly to drive the shaking plate 30 and the hook 4 to shake, avoiding the formation of a stable shielding between the hook 4 and the aluminum single plate hanging place, and realizing comprehensive and uniform painting.

[0035] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.

10. A process for coating the surface of an aluminum plate, based on the aluminum plate surface coating spraying equipment according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: First, according to the shape and structure of the aluminum veneer to be sprayed, the aluminum veneer is reasonably hung on the hook (4), and the guide rail (3) is controlled to drive the hook (4) and the aluminum veneer hung thereon to slide intermittently; Step 2: When the aluminum veneer passes through the spray head (15) and faces the spray head (15), the guide rail (3) is controlled to stop running, and then the slide rail (2) is started to drive the slide seat 1 (6) to slide up and down reciprocatingly, so as to spray one side of the aluminum veneer; Step 3: When the aluminum plate cannot be effectively painted at some positions due to its shape and structure, first control the slide rail (2) to drive the slide seat (6) to move to the top or bottom, start the drive assembly to control the vertical plate (24) to slide toward the horizontal plate (10), until the vertical plate (24) is directly above the horizontal plate (10) or directly above and coincides with the path of the horizontal plate (10) sliding up and down; Step 4: Start the slide rail (2) again to drive the slide seat (6) to slide up and down. At this time, the horizontal plate (10) located directly above or directly above the vertical plate (24) will come into contact with one end of the vertical plate (24) and rotate. In the process, the turntable (8), the connecting plate (9) and the nozzle (15) installed in the installation frame (13) will be driven to spray with the angle adjusted up and down; Step 5: When the connecting plate (9) rotates, the adjusting component adjusting nozzle (15) will be driven to rotate in the front-rear direction, so that the upward and downward tilted spraying can be performed while also performing the front-rear tilted spraying; Step 6: When the slide seat 1 (6) slides to the top of the slide rail (2), it can cooperate with the linkage assembly to drive the shaking plate (30) and the hook (4) to shake, thereby preventing the hook (4) and the aluminum plate from forming a stable shielding at the hanging position, thereby achieving full and uniform painting.
