Description

Technical Field

[0001] This utility model relates to the field of aluminum profile powder coating technology, and in particular to an aluminum profile powder coating equipment. Background Technology

[0002] Aluminum profile powder coating equipment is a specialized device used for powder coating treatment of aluminum profile surfaces. Its function is to form an aesthetically pleasing and corrosion-resistant surface coating by spraying powder coating and curing it. It is used for aluminum profile surface treatment in the construction, automotive, and electronics industries. The electrostatic powder spray gun generates a high-voltage electrostatic field. When the powder coating is sprayed from the gun head, it carries a negative charge, while the grounded aluminum profile carries a positive charge. Through electrostatic adsorption, the powder is evenly adhered to the profile surface to form a powder coating.

[0003] For aluminum profiles with complex internal cavities, deep holes, or irregular shapes, electrostatic powder coating can lead to uneven coating due to electric field shielding, requiring manual touch-up spraying or adjustment of the spray gun angle, which affects efficiency. Existing technologies use spray guns with a surrounding electrostatic field, which can penetrate deep holes or internal cavities and use electrostatic adsorption to make the powder adhere evenly to corners that are difficult to reach by traditional spray guns, reducing manual touch-up spraying. However, in actual use, when spraying in multiple directions, the powder splashes over a wider range and will deposit on the inner wall of the powder spraying booth, the joints of the robotic arm, the surface of the sensor, and even enter the heat dissipation holes of the motor, affecting the stability of equipment operation.

Detailed Implementation

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Reference Figure 2 and Figure 3 An embodiment of this utility model provides: an aluminum profile powder spraying device, including a powder spraying box 1, a rotating mechanism 2 is provided on the top inner side of the powder spraying box 1, the rotating mechanism 2 is used to rotate the aluminum profile for uniform spraying, a moving mechanism 3 is provided on the top inner side of the powder spraying box 1, the top of the rotating mechanism 2 is fixedly connected to the bottom of the moving mechanism 3, spraying mechanisms 4 are provided on both the front and rear sides of the inside of the powder spraying box 1, and two fixing blocks 5 are fixedly connected to the front left and right sides of the powder spraying box 1, and dust blocking mechanisms 6 are provided between the adjacent fixing blocks 5, the dust blocking mechanisms 6 are used to block the dust inside the powder spraying box 1 from escaping;

[0026] The rotating mechanism 2 includes a placement box 21. The top of the placement box 21 is fixedly connected to the bottom of the moving mechanism 3. A bracket 22 is fixedly connected inside the placement box 21. A motor 23 is fixedly connected to the top of the bracket 22. A bearing 24 is fixedly connected to the output end of the motor 23. Support rods 25 are fixedly connected to the bottom of the bearing 24. A connecting rod 26 is fixedly connected to the bottom of the bearing 24. A placement component 27 is provided at the bottom of the connecting rod 26. An installation component 28 is provided on the right side of the placement box 21.

[0027] Specifically, the rotating mechanism 2 uses the placement box 21 as a carrier, with its top fixedly connected to the bottom of the moving mechanism 3 to ensure the overall structure is stable. The bracket 22 inside the placement box 21 serves as a support component, fixing the motor 23 in the middle of the placement box 21. When the motor 23 is powered on, its output drives the bearing 24 to rotate. The support rods 25 fixed around the bottom of the bearing 24 and the connecting rod 26 fixed at the bottom center together form a stable transmission structure. The support rods 25 enhance the stability of the bearing 24 during rotation, preventing wobbling due to uneven force. The connecting rod 26 transmits the rotational power downwards to the placement assembly 27, which is installed at the bottom of the connecting rod 26 and used to place the aluminum profile. When the motor 23 operates, it drives the placement assembly 27 to rotate via the bearing 24 and connecting rod 26, thereby causing the clamped aluminum profile to rotate circumferentially. The mounting component 28 on the right is used to install the motor 23 inside the placement box 21. During the powder coating operation, after the aluminum profile is fixed by the placement component 27, the motor 23 starts, and the aluminum profile begins to rotate at a constant speed. At this time, the spraying mechanism 4 on the front and rear sides inside the powder coating box 1 sprays powder onto the surface of the aluminum profile. Since the aluminum profile is rotating, the powder can evenly cover all surfaces of the aluminum profile, avoiding local over-thickness or missed spraying. The motor 23 drives the bearing 24 to rotate, and the power is transmitted to the placement component 27 through the connecting rod 26 to achieve stable rotation of the aluminum profile. The bracket 22 and the support rod 25 enhance the structural stability during the rotation process, enabling the rotation mechanism 2 to provide continuous and stable rotation for the aluminum profile, ensuring the uniformity and efficiency of the powder coating operation, effectively improving the powder coating quality of the aluminum profile surface, and reducing rework or defective products caused by uneven powder coating.

[0028] Reference Figure 1 , Figure 4 and Figure 5 The dust-blocking mechanism 6 includes two rotating rods 61. The upper and lower ends of the outer walls of the two rotating rods 61 are rotatably connected between adjacent fixed blocks 5. Baffles 62 are fixedly connected to the rear side of the outer walls of the two rotating rods 61. A locking post 63 is fixedly connected to the rear side of the two baffles 62. Two locking blocks 64 are fixedly connected to the rear ends of the left and right sides of the powder spraying box 1. Springs 65 are fixedly connected between adjacent locking blocks 64. Locking blocks 66 are fixedly connected between adjacent springs 65. Pulling components 67 are provided on the top of the two top locking blocks 64.

[0029] Specifically, the dust-blocking mechanism 6 uses a rotating rod 61 as its rotational base, with its upper and lower ends rotatably connected to the fixed block 5, allowing the rotating rod 61 to swing in the vertical plane. The baffle 62 fixed to the rear of the rotating rod 61 rotates synchronously with the rotating rod 61 to prevent dust from overflowing from the powder spraying box 1. The locking post 63 on the rear of the baffle 62, together with the locking block 64, spring 65, and locking block 66 on the rear of the powder spraying box 1, form an elastic locking structure. In the initial state, the spring 65 is in a compressed state, pushing the locking block 66 to lock the locking post 63, causing the baffle 62 to... Maintaining a vertical position, the aluminum profile is tightly fitted to the front opening of the powder coating box 1, forming a closed barrier. When placing or removing the aluminum profile, the operator pulls the top locking block 64 upwards using the pull-opening assembly 67, causing the spring 65 and the locking block 66 to move upwards, releasing the locking block 66 from the locking post 63. The rotating rod 61 loses its lateral constraint and can rotate around the fixed block 5, causing the baffle 62 to open outwards, forming an operating opening. After the aluminum profile is placed, the pull-opening assembly 67 is released, and the elastic restoring force of the spring 65 pushes the locking block 66 downwards. The locking pin 63 is re-locked, and the rotating rod 61 resets under gravity, causing the baffle 62 to rotate back to the vertical position, thus closing the front opening of the powder spraying box 1 again. This ensures that the baffle 62 remains stable and closed despite airflow disturbances inside the powder spraying box 1, preventing dust leakage. During powder spraying operations, the baffle 62 fits tightly against the front of the powder spraying box 1, and in conjunction with the closed structure of the powder spraying box 1, it confines the dust inside the box. Even when the high-speed powder spraying by the spraying mechanism 4 causes internal airflow fluctuations, the elasticity of the spring 65 keeps the locking block 66 in place. Finally, the clamping post 63 is pressed to prevent the baffle 62 from shifting. The rotational connection between the rotating rod 61 and the fixed block 5 enables the convenient opening and closing of the baffle 62. The elastic engagement of the spring 65, the clamping block 66, and the clamping post 63 ensures the stability of the baffle 62 in the closed state. The lifting operation of the pulling assembly 67 enables the dust blocking mechanism 6 to be quickly unlocked and reset, effectively preventing the dust inside the powder spraying box 1 from overflowing, reducing dust pollution in the workshop, and facilitating the loading and unloading of aluminum profiles by operators, thus improving the safety and convenience of equipment use.

[0030] Reference Figure 3 and Figure 5The placement component 27 includes a placement plate 271, the top of which is fixedly connected to the bottom of the connecting rod 26. Multiple fixing strips 272 are fixedly connected to the front and rear sides of the placement plate 271. Two bolts 273 are threadedly connected to the opposite sides of the multiple fixing strips 272. Hooks 274 are fixedly connected to the opposite sides of the multiple fixing strips 272. The installation component 28 includes a fixing plate 281, the left side of which is fixedly connected to the right side of the placement box 21. Bolts 282 are threadedly connected to the four corners of the right side of the fixing plate 281. The pull-and-close component 67 includes two pull rods 672. The outer walls of the two pull rods 672 are slidably connected to the inside of two top locking blocks 64. The top of each of the two top locking blocks 64 has a round hole 671. The outer walls of the two pull rods 672 are slidably connected to the inside of the round hole 671. Pull rings 673 are fixedly connected to the top of the two pull rods 672.

[0031] Specifically, the placement component 27 uses the placement plate 271 as its support base. Its top is fixedly connected to the bottom of the connecting rod 26 and rotates synchronously with the bearing 24. The fixing strips 272 on the front and rear sides of the placement plate 271 provide fixing points. The operator places the aluminum profile between the fixing strips 272 and clamps and fixes the aluminum profile to the inside of the fixing strips 272 by tightening the bolts 273. The hooks 274 on the outside of the fixing strips 272 can help hang small accessories or tools to prevent items from falling and affecting the powder spraying process during operation. After installation, the aluminum profile rotates at a uniform speed with the placement plate 271 to ensure uniform powder spraying coverage. The fixing plate 281 of the installation component 28 is fixedly connected to the inside of the powder spraying box 1 by four bolts 282. During installation, align the right side of the fixing plate 281 with the preset screw holes of the powder spraying box 1 and tighten the bolts 282 in sequence to make the placement box 21 firmly installed on the powder spraying box 1. At the top of powder box 1, during disassembly, simply loosen bolt 282 in the reverse direction to separate the rotating mechanism 2, facilitating equipment maintenance or component replacement. This structure ensures the stability of the rotating mechanism 2 during motor 23 operation, preventing displacement of the aluminum profile due to vibration. The pull-and-close assembly 67 controls the opening and closing of the dust-blocking mechanism 6. Two pull rods 672 pass through the round hole 671 of the top locking block 64 and are fixedly connected to the pull ring 673 at the top. When it is necessary to open the baffle 62, the operator pulls the pull ring 673 upward, causing the pull rod 672 to move upward against the elastic force of the spring 65, so that the locking block 66 disengages from the locking position of the locking post 63. At this time, the rotating rod 61 is unrestrained and can rotate around the fixed block 5, causing the baffle 62 to open outward. After releasing the pull ring 673, the spring 65 pushes the locking block 66 to reset, re-locking the locking post 63, so that the baffle 62 rotates back to the vertical position to close the opening of the powder spraying box 1.

[0032] Reference Figure 2The moving mechanism 3 includes a slide rail 31, the top of which is fixedly connected to the top of the inner side of the powder spraying box 1. A slider 32 is slidably connected to the bottom of the slide rail 31. A connecting block 33 is fixedly connected to the bottom of the slider 32. The moving mechanism 3 also includes a telescopic rod 34, the left end of which is fixedly connected to the top of the inner side of the powder spraying box 1. A connecting block 35 is fixedly connected to the right side of the telescopic rod 34. The front side of the connecting block 35 is fixedly connected to the rear side of the connecting block 33. The spraying mechanism 4 includes multiple slide rails 41, the opposite sides of which are fixedly connected to the front and rear sides of the powder spraying box 1. Slider 42 is slidably connected between adjacent slide rails 41. Telescopic rod 43 is fixedly connected to the top of each slider 42. Placement plate 44 is fixedly connected between adjacent telescopic rods 43. Multiple spray guns 45 are fixedly connected between adjacent placement plates 44.

[0033] Specifically, the placement component 27 uses the placement plate 271 as its supporting base. Its top is fixedly connected to the bottom of the connecting rod 26 and rotates synchronously with the bearing 24. The fixing strips 272 on the front and rear sides of the placement plate 271 provide fixing points. The operator places the aluminum profile between the hooks 274 and fixes the fixing strips 272 to the front and rear sides of the placement plate 271 by tightening the bolts 273. After installation, the aluminum profile rotates at a uniform speed with the placement plate 271 to ensure uniform powder coating. The fixing plate 281 of the installation component 28 is fixedly connected to the inside of the powder spraying box 1 by four bolts 282. During installation, align the right side of the fixing plate 281 with the preset screw holes of the powder spraying box 1 and tighten the bolts 282 in sequence to make the placement box 21 securely installed on the top of the powder spraying box 1. When disassembling, loosen the bolts 282 in the opposite direction. 2. The fixed plate 281 can be opened to facilitate equipment maintenance or component replacement. This structure ensures that the rotating mechanism 2 remains stable when the motor 23 is running, and avoids displacement of the aluminum profile due to vibration. The pull-open assembly 67 is used to control the opening and closing of the dust blocking mechanism 6. Two pull rods 672 pass through the round hole 671 of the top locking block 64 and are fixedly connected to the pull ring 673 at the top. When it is necessary to open the baffle 62, the operator pulls the pull ring 673 upward, which drives the pull rod 672 to move upward against the elastic force of the spring 65, so that the locking block 66 is released from the locking position of the locking post 63. The rotating rod 61 is unrestrained and can rotate around the fixed block 5, which drives the baffle 62 to open outward. After the pull ring 673 is released, the spring 65 pushes the locking block 66 to reset and re-lock the locking post 63, so that the baffle 62 rotates back to the vertical position to close the opening of the powder spraying box 1.

[0034] Working principle: The operator first clamps the aluminum profile, placing it on the placement plate 271 of the placement component 27. The aluminum profile is positioned between the front and rear fixing strips 272 and initially positioned using hooks 274. Bolts 273 are tightened to clamp and fix the aluminum profile, ensuring it is securely installed on the placement plate 271. Next, the rotating mechanism 2 is installed. The right side of the fixing plate 281 of the installation component 28 is aligned with the pre-set screw holes inside the powder spraying box 1. Four bolts 282 are tightened sequentially to securely install the placement box 21 on top of the powder spraying box 1. At this point, the rotating mechanism 2 and the moving mechanism 3 are connected. The top of the placement box 21 is fixedly connected to the slider 32 at the bottom of the moving mechanism 3, ensuring the overall structure is stable. The moving mechanism 3 begins to operate. The control system issues a command to extend and retract the telescopic rod 34. The connecting block 35 at the right end of the telescopic rod 34 drives the connecting block 33, which in turn drives the slider 32 to move horizontally along the slide rail 31. By precisely controlling the extension and retraction of the telescopic rod 34, the rotating mechanism 2 and the aluminum profile can be moved to the target lateral position inside the powder spraying box 1. The spraying mechanism 4 is adjusted. Multiple slide rails 41 are fixed inside the powder spraying box 1 on the front and back sides. The slider 42 slides longitudinally along the slide rails 41. The telescopic rod 43 at the top of the slider 42 is connected to the placement plate 44. The control system independently controls the extension and retraction of each telescopic rod 43 according to the size and shape of the aluminum profile. The extension and retraction of the telescopic rod 43 causes the placement plate 44 to move up and down and form an inclined surface at different angles, thereby adjusting the height and spraying angle of multiple spray guns 45 between the placement plates 44 to ensure that the spray guns 45 are in the optimal powder spraying position. After the position of the aluminum profile and the spray guns 45 is adjusted, the rotating mechanism 2 is started, and the motor 23 inside the placement box 21 is powered on. Its output end drives the bearing 24 to rotate. The support rods 25 around the bottom of the bearing 24 enhance the stability during rotation and prevent shaking due to uneven force.The connecting rod 26 at the bottom center transmits the rotational power downwards to the placement component 27. The placement plate 271 rotates synchronously with the connecting rod 26, thereby causing the fixed aluminum profile to rotate circumferentially. The spraying mechanism 4 starts working, and the spray gun 45 uses a pressure nozzle to spray powder onto the surface of the rotating aluminum profile. Since the aluminum profile is rotating at a uniform speed and the position and angle of the spray gun 45 have been adjusted in advance, the powder can evenly cover all surfaces of the aluminum profile. The moving mechanism 3 continues to operate, driving the aluminum profile to move laterally. In conjunction with the fixed spray range of the spray gun 45, it ensures that the entire length of the aluminum profile is evenly powdered, avoiding situations where the powder is too thick in some areas or missed. Throughout the entire powder spraying process... During operation, the dust-blocking mechanism 6 always functions. In the initial state, the spring 65 is compressed, pushing the locking block 66 to lock the locking post 63 on the rear side of the baffle 62, keeping the baffle 62 vertical and tightly fitted to the front opening of the powder spraying box 1, forming a closed barrier. Even when the high-speed powder spraying by the spraying mechanism 4 causes internal airflow fluctuations, the elasticity of the spring 65 keeps the locking block 66 pressed against the locking post 63, preventing the baffle 62 from shifting and effectively confining the dust inside the powder spraying box 1. When it is necessary to place or remove aluminum profiles, the operator pulls the pull ring 673 of the pull-and-close assembly 67 upwards, causing the pull rod 672 to move upwards against the elastic force of the spring 65, causing the locking block 66 to disengage from the locked position of the locking post 63, and the rotating rod 61 to disengage. Remove the lateral constraint, rotate around the fixed block 5, causing the baffle 62 to open outward, forming an operating opening. After the aluminum profile is placed or removed, release the pull ring 673. The elastic restoring force of the spring 65 pushes the locking block 66 downward, re-locking the locking post 63. The rotating rod 61 resets under gravity, causing the baffle 62 to rotate back to the vertical position, closing the front opening of the powder spraying box 1 again to prevent dust leakage and reduce dust pollution in the workshop. After the powder spraying operation is completed, the motor 23 stops running, the aluminum profile stops rotating, and the operator opens the baffle 62 again through the pull-opening assembly 67, uses a tool to loosen the bolt 273, loosens the fixing strip 272, and removes the powder-sprayed aluminum profile from the placement plate 271. If the equipment requires maintenance or parts replacement, bolt 282 can be loosened in reverse, fixing plate 281 can be removed, and the rotating mechanism 2 can be maintained. The aluminum profile is securely clamped and the equipment installed via placement component 27 and installation component 28. Precise adjustments to the moving mechanism 3 and spraying mechanism 4 ensure that the spray gun 45 sprays powder onto the aluminum profile from all directions and multiple angles. The rotating mechanism 2 ensures uniform powder spraying by making the aluminum profile rotate at a constant speed. The dust-blocking mechanism 6 effectively prevents dust from overflowing, improving operational safety, significantly improving the efficiency and quality of aluminum profile powder spraying, reducing rework caused by manual intervention and uneven powder spraying, while also reducing dust pollution in the workshop and improving the convenience and reliability of equipment use.
