Description

Technical Field

[0001] This utility model relates to the field of strip profile spraying technology, specifically to a multi-layer uniform spraying electrostatic powder spraying device for strip profiles. Background Technology

[0002] On the production line for processing metal strip profiles, especially aluminum strip profiles, electrostatic powder coating is often applied to enhance the corrosion resistance and wear resistance of the profiles, which often requires specialized electrostatic powder coating equipment.

[0003] For example, the electrostatic powder coating device for strip profiles disclosed on the patent website (authorization announcement number: CN221157214U) achieves the effect of simultaneously conveying multiple layers of profiles by vertically arranging several layers of material rods on the material rack. The profiles enter and exit the coating chamber via a conveyor device, and the set spraying mechanism sprays each layer of profiles vertically, realizing online automated spraying of strip profiles while they are being conveyed. However, in practical applications, this existing device, because its spraying mechanism can only spray each layer of profile vertically, results in uneven spraying under the action of the spray gun. The coating area is relatively fixed, and the sprayed powder tends to accumulate on the profile surface, resulting in poor coating effect. In addition, the existing device can only spray the two ends of the strip profile at most in a single operation. When different ends need to be sprayed, the strip profile needs to be manually flipped after a single operation before spraying, which is cumbersome and inefficient. Therefore, in order to solve the above problems, we urgently need to improve the multi-layer uniform spraying electrostatic powder coating device for strip profiles. Utility Model Content

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a multi-layer uniform spraying type electrostatic powder spraying device for strip profiles, including a mounting plate 1 and a powder feeding device 3 on its top, a working frame 2, and multiple sets of electrostatic spraying heads 4 that can be connected to the powder feeding device 3 to spray the strip profiles 8.

The working frame 2 is provided with an electric guide rail 6. The electric guide rail 6 is provided with a multi-layer placement mechanism 7 for placing and rotating the strip profiles 8.

[0025] Furthermore, the spraying adjustment mechanism 5 includes a height adjustment component 51 for adjusting the height of the electrostatic spraying head 4. The height adjustment component 51 has at least two sets of mounting frames 511. The mounting frames 511 are fixedly installed inside the working frame 2. A motor base 512 is fixedly installed inside the mounting frame 511. A drive motor 513 is fixedly installed inside the motor base 512. A threaded rod 514 is fixedly installed on the output shaft of the drive motor 513. A limit rod 515 is fixedly installed inside the mounting frame 511. A movable block 516 is threadedly installed on the outside of the threaded rod 514. A connecting seat 517 is fixedly installed on the outside of the movable block 516, so that the height of the movable block 516 can be adjusted according to the spraying processing requirements, thereby adjusting the height of the electrostatic spraying head 4 and spraying the strip profile 8 at different positions.

[0026] Furthermore, the movable block 516 has a through hole for the limiting rod 515 to pass through, and the mounting frame 511 has a limiting groove for the movable block 516 to slide, so as to prevent the movable block 516 from rotating with the threaded rod 514 when the height of the movable block 516 is adjusted.

[0027] Furthermore, the spraying adjustment mechanism 5 also includes a swing component 52 for adjusting the angle of the electrostatic spraying head 4 to achieve a swing spraying effect. The swing component 52 is provided with a first connecting plate 521, which is fixedly installed on the outside of the movable block 516. A movable plate 522 is rotatably installed on the top of the first connecting plate 521. A reduction motor 523 is fixedly installed inside the connecting seat 517. A second connecting plate 524 is fixedly installed on the output shaft of the reduction motor 523. A sliding sleeve 525 is slidably installed on the outside of the movable plate 522 to facilitate the swing of the movable plate 522, thereby achieving the swing of the electrostatic spraying head 4 and achieving a uniform spraying effect.

[0028] Furthermore, the movable plate 522 is fixedly installed on the outside of the electrostatic spraying head 4, and the second connecting plate 524 is movably installed on the sliding sleeve 525, which facilitates the stable swing of the movable plate 522 and allows the position of the movable plate 522 to be dynamically locked after reaching the required angle.

[0029] Example 2: Please refer to Figures 6-7 Furthermore, in conjunction with Embodiment 1, the multi-layer placement mechanism 7 includes a slider 71 movably installed inside the electric guide rail 6. A connecting frame 72 is fixedly installed at the bottom of the slider 71. A first motor 73 is fixedly installed inside the slider 71. A worm gear assembly 74 is fixedly installed on the output shaft of the first motor 73. A connecting rod 75 is rotatably installed inside the connecting frame 72. A worm wheel 76 is fixedly installed outside the connecting rod 75. A connecting frame 77 is fixedly installed outside the slider 71. A telescopic push rod 78 is fixedly installed inside the connecting frame 77, which facilitates the placement of strip profiles 8 of different sizes and specifications, and allows the strip profiles 8 to be rotated for spraying different end faces of the strip profiles 8.

[0030] Furthermore, the worm gear assembly 74 engages with the connecting rod 75, which facilitates the stable rotation of the strip profile 8. The strip profile 8 is positioned between the telescopic push rod 78 and the connecting rod 75, and can be rotatably installed with the telescopic push rod 78 and the connecting rod 75, which facilitates the dynamic placement of the strip profile 8.

[0031] In actual operation, when it is necessary to spray the strip profile 8, the strip profile 8 can first be placed on one side of the connecting rod 75, so that the strip profile 8 and the connecting rod 75 are rotated and installed. Then, according to the size specifications of the strip profile 8, the telescopic push rod 78 can be adjusted to limit the other side of the strip profile 8. Then, the electric guide rail 6 can be operated to move the placed strip profile 8 into the working frame 2. Then, the powder feeding equipment 3 can be operated to supply powder coating into the electrostatic spray head 4. Under the action of the electrostatic spraying head 4, the strip profile 8 can be sprayed. To improve the spraying effect on the strip profile 8, the drive motor 513 can be turned on, causing the threaded rod 514 to rotate. Under the action of the limit rod 515, the movable block 516 slides inside the limit groove inside the mounting frame 511, thereby changing the height of the electrostatic spraying head 4 and spraying the strip profile 8 at different placement positions. By controlling the forward and reverse rotation of the drive motor 513, the up and down reciprocating motion of the movable block 516 can be realized. Subsequently, for To further increase the spraying area of ​​the strip profile 8 and prevent powder from accumulating in one place, the geared motor 523 can be turned on while the height of the movable block 516 is changed, causing the second connecting plate 524 to rotate. This allows the sliding sleeve 525 to slide outside the movable plate 522, thereby driving the movable plate 522 to rotate and change the angle of the electrostatic spray head 4. By repeatedly running the geared motor 523, the reciprocating oscillation of the electrostatic spray head 4 can be achieved. When it is necessary to fix the angle of the electrostatic spray head 4, it can be fixed in place. After the electrostatic spray head 4 reaches the required angle, the reduction motor 523 is turned off, and the angle of the electrostatic spray head 4 can be fixed. When it is necessary to spray different end faces of the strip profile 8, the first motor 73 can be turned on to make the worm gear assembly 74 rotate, thereby driving the worm wheel 76 meshing with the worm gear assembly 74 to rotate, and making the connecting rod 75 rotate. With the assistance of the telescopic push rod 78, the strip profile 8 can be rotated to spray different end faces of the strip profile 8, improve the spraying effect, and enhance the practicality of the device.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
