Description

Technical Field

[0001] The present invention relates to the field of coatings for aluminum veneers, especially the coating process and painting equipment for the surface of aluminum veneers. Background Art

[0002] Aluminum veneers are mainly based on aluminum alloy plates. Commonly used aluminum alloy materials include AA1100 pure aluminum plates, AA3003 alloy aluminum plates, etc. These aluminum alloy materials have characteristics such as low density, high strength, and corrosion resistance, providing good basic properties for aluminum veneers. In actual production, some other elements may also be added or alloying treatment may be carried out according to needs to further improve the properties of the materials, such as increasing hardness and toughness.

[0003] When processing aluminum veneers, it generally includes three processes: plate cutting, forming processing, and surface treatment. Surface treatment is the key link in the processing of aluminum veneers. Common surface treatment processes include fluorocarbon spraying, polyester spraying, anodic oxidation, powder spraying, etc. Taking fluorocarbon spraying as an example, it is to evenly coat the paint containing fluorocarbon resin on the surface of the aluminum plate through electrostatic spraying and other methods, and then cure it through high-temperature baking to form a layer of firm, durable, and having good weather resistance and decorative coating.

[0004] Currently, the nozzles for painting aluminum veneers are fixedly arranged, and they can only move vertically up and down following the driving member to achieve reciprocating spraying, but the angle of the nozzles cannot be adjusted during the painting process. Due to the various shapes and structures of aluminum veneers, during specific painting, it is easy to cause some painting dead corners due to the shape and structure of the aluminum veneer itself. Then, the nozzles need to spray reciprocally multiple times. Reciprocal spraying multiple times easily leads to too thick coating spraying in other areas, while the spraying in the dead corner areas is relatively thin, resulting in uneven painting and reducing the quality of painting. Therefore, a surface coating process and painting equipment for aluminum veneers are proposed. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the present invention proposes a surface coating process and painting equipment for aluminum veneers, which can adjust the nozzles at multiple angles when painting aluminum veneers, avoid painting dead corners caused by the shape and structure of the aluminum veneer itself, and improve the uniformity of painting and the quality of the finally formed coating.

[0017] A surface coating process for an aluminum single plate comprises the following steps:

[0018] Step 1: First, according to the shape and structure of the aluminum veneer to be sprayed, reasonably hang the aluminum veneer on the hook, and control the guide rail to drive the hook and the aluminum veneer hung on it to slide intermittently;

[0019] Step 2: When the aluminum veneer passes through the nozzle and faces the nozzle, the guide rail is controlled to stop running, and then the slide rail is started to drive the slide seat to slide up and down to spray one side of the aluminum veneer;

[0020] Step 3: When the aluminum veneer cannot be effectively painted in some places due to its shape and structure, first control the slide rail to drive the slide seat to move to the top or bottom, start the drive assembly to control the vertical plate to slide toward the horizontal plate, until the vertical plate is directly above the horizontal plate or directly above it coincides with the path of the horizontal plate sliding up and down;

[0021] Step 4: Start the slide rail again to drive the slide seat to slide up and down. At this time, the horizontal plate directly above or directly above the vertical plate will contact with one end of the vertical plate and rotate. During this process, the turntable, the connecting plate and the nozzle installed in the installation frame will be driven to spray at an angle of up and down;

[0022] Step 5: When the connecting plate rotates, the adjusting component will drive the nozzle to rotate in the front-to-back direction, so that the nozzle can be tilted up and down and tilted forward and backward at the same time;

[0023] Step 6: When the slide seat slides to the top of the slide rail, it can cooperate with the linkage assembly to drive the shaking plate and the hook to shake, avoiding the formation of a stable cover between the hook and the aluminum panel hanging place, and achieving comprehensive and uniform painting.

[0024] The beneficial effects of the present invention are:

[0025] 1. The technical solution of the present invention drives the slide seat 1 and the nozzle installed on it through the turntable and the horizontal plate to move up and down reciprocatingly through the slide rail to spray paint the aluminum single plate hung on the hook on one side thereof, and at the same time, the vertical plate can be driven to move toward one side of the horizontal plate through the driving component, so that the horizontal plate conflicts with the vertical plate and deflects in an inclined manner during the process of following the up and down movement of the slide rail, thereby driving the nozzle on the other side to adjust the pitch angle, so as to realize the comprehensive and non-dead angle spraying of aluminum single plates with different shapes and structures;

[0026] 2. 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;

[0027] 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.

[0044] A mounting frame 13 is connected to the connecting plate 9, and a nozzle 15 is rotatably connected inside the mounting frame 13. 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.

[0045] Embodiment 2:

[0046] 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.

[0047] 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.

[0048] The two ends of the installation frame 13 are rotatably sleeved with rotating shafts 14 through which they penetrate. The spray head 15 is installed on the surface of the rotating shaft 14 inside the installation frame 13. The gear 16 is connected to the extending ends of the rotating shaft 14 on the upper and lower sides of the installation frame 13. The two ends of the sliding frame 20 extend to the two outer sides of the installation frame 13. The sliding frame 20 has an extension on the two outer sides of the installation frame 13, enabling the second sliding seat 18 and the sliding frame 20 to have a sliding space for moving back and forth.

[0049] As Figure 3 and 4 shown, before the driving component acts on the vertical plate 24 to make it slide, first drive the first sliding seat 6 to move to the highest or lowest position through the slide rail 2, so that the turntable 8, the connecting plate 9 and the cross plate 10 move accordingly at this time, and then drive the vertical plate 24 to move to directly below the cross plate 10 at the highest position, or directly above the cross plate 10 at the lowest position;

[0050] Taking the first sliding seat 6 moving to the lowest position as an example:

[0051] After adjusting the position of the vertical plate 24, control the slide rail 2 to drive the first sliding seat 6 to move upward. The cross plate 10 will come into contact with the lower end of the vertical plate 24, causing the cross plate 10 to deflect and slide on the surface of the vertical plate 24. During this process, the spray head 15 inside the installation frame 13 will also be driven to deflect upward until it slides to the other end of the vertical plate 24, and then reset to the horizontal balance state under the action of the first spring 12. When the cross plate 10 is driven to move downward again, the cross plate 10 will come into contact with the upper end of the vertical plate 24, driving the spray head 15 inside the installation frame 13 to deflect downward, realizing the adjustment of the up and down deflection spraying of the spray head 15;

[0052] At the same time, when the spray head 15 is driven to deflect upward, the trapezoidal block 22 connected to the front side of the sliding frame 20 will come into contact with the limiting plate 23 connected above the first sliding seat 6 on the front side, pushing the sliding frame 20 and the rack 21 to move backward. Furthermore, the spray head 15 driven to deflect upward can also be synchronously deflected forward. Similarly, when the spray head 15 is driven to deflect downward, the trapezoidal block 22 connected to the rear side of the sliding frame 20 will come into contact with the limiting plate 23 connected below the first sliding seat 6 on the rear side, pushing the sliding frame 20 and the rack 21 to move forward. Furthermore, the spray head 15 driven to deflect downward can also be synchronously deflected backward;

[0053] In this way, when spraying aluminum single plates with special shape structures and forming spraying dead corners, by adjusting the vertical plate 24, the spray head 15 can perform multi-angle spraying, overcoming the problems of dead corners that cannot be sprayed and uneven spraying, and improving the quality of the formed coating.

[0054] The same principle applies to the first sliding seat 6 moving to the highest position before the vertical plate 24 is adjusted, and will not be elaborated here.

[0055] Embodiment Three:

[0056] like Figure 1-10 As 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] Embodiment 4:

[0061] 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.

[0062] The driving assembly includes a bidirectional telescopic member 25 and a hinge seat 26. The bidirectional telescopic member 25 is installed on the bracket 1, and the hinge seat 26 is connected to the telescopic ends on both sides of the bidirectional telescopic member 25. A rotating plate 27 is rotatably connected between each hinge seat 26 and the vertical plate 24. Driving the rotating plate 27 to rotate through the bidirectional telescopic member 25 realizes the driving of the vertical plate 24, which is convenient for controlling the moving distance of the vertical plate 24, because the angular deflection amplitude of the nozzle 15 can be adjusted by adjusting the position of the vertical plate 24 directly above or directly below the cross plate 10.

[0063] Sliders 5 are connected to the mutually remote sides of the two sliding seats one 6. The sliders 5 are slidably connected within the slide rails 2. A slide bar 7 is also connected to the bracket 1. The sliding seat one 6 is slidably sleeved on the outer side of the slide bar 7. The arrangement of the sliders 5 and the slide bar 7 facilitates the stability during the movement of the sliding seat one 6 and the devices thereon.

[0064] Embodiment Five:

[0065] As Figure 1-10 shown, the present invention discloses a surface coating process for aluminum single plates, including the following steps:

[0066] Step One: First, according to the shape and structure of the aluminum single plate to be sprayed, reasonably hang the aluminum single plate on the hook 4, and control the guide rail 3 to drive the hook 4 and the aluminum single plate suspended thereon to slide intermittently;

[0067] Step Two: When the aluminum single plate passes by and faces the nozzle 15, control the guide rail 3 to stop running, and then start the slide rail 2 to drive the sliding seat one 6 to slide up and down reciprocally to spray one side of the aluminum single plate;

[0068] Step Three: When some positions of the aluminum single plate cannot be effectively painted due to its shape and structure, first control the slide rail 2 to drive the sliding seat one 6 to move to the uppermost or lowermost position, start the driving assembly to control the vertical plate 24 to slide towards the cross plate 10 until the vertical plate 24 is directly above the cross plate 10 or the sliding path of the vertical plate 24 sliding up and down coincides with that of the cross plate 10;

[0069] Step Four: Start the slide rail 2 again to drive the sliding seat one 6 to slide up and down reciprocally. At this time, the cross plate 10 directly above or above the vertical plate 24 will contact and rotate with one end of the vertical plate 24, and during the process, it will drive the rotating disc 8, the connecting plate 9, and the nozzle 15 installed in the installation frame 13 to perform spraying with up and down angle adjustment;

[0070] Step Five: When the connecting plate 9 rotates, it will drive the adjusting assembly to adjust the nozzle 15 to rotate in the front - rear direction, realizing front - rear inclined spraying while performing up - down inclined spraying;

[0071] Step Six: When the first sliding seat 6 slides to the high position of the slide rail 2, it can cooperate with the linkage assembly to drive the shaking plate 30 and the hook 4 to shake, preventing the hook 4 from forming a stable occlusion at the hanging position of the aluminum single plate, and achieving comprehensive and uniform painting.

[0072] According to the disclosure and teaching of the above specification, those skilled in the art to which the present invention pertains can 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 protection scope of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
