[0002] In modern architectural decoration, transportation and industrial manufacturing, aluminum single panels are widely used in curtain walls, ceilings, partitions, billboards and other scenarios due to their advantages such as light weight, high strength, corrosion resistance, easy processing and forming and good surface decoration. In order to improve the aesthetics, weather resistance and pollution resistance of aluminum single panels, it is usually necessary to spray them on the surface, such as fluorocarbon spraying, powder spraying or polyester spraying.

[0003] In the process of spraying aluminum panels, the spraying pressure and spray gun movement speed are usually preset and adjusted manually.

[0018] The spraying assembly 2 includes connecting shells 21 fixedly connected to both sides of the workbench 11. A motor 22 is fixedly connected to one side of one connecting shell 21.

[0022] Example 2 The control component 4 includes a mounting shell 41 fixedly connected to one side of the workbench 11. The side wall of the mounting shell 41 has a through hole for heat dissipation and a filter screen can also be fixed inside the through hole to prevent the entry of external debris. A first metal strip 42 is fixedly connected to the inner side of the mounting shell 41. A first slider 43 is slidably disposed on the outer side of the first metal strip 42. Both the first slider 43 and the second slider 49 are made of conductive material. A mounting block 44 is fixedly connected to one side of the first slider 43 and slidably disposed on the bottom inner side of the mounting shell 41. Correspondingly, a first guide groove adapted to the mounting block 44 is provided on the bottom inner side of the mounting shell 41. The mounting block 44 is slidably disposed along the first guide groove, which can guide and limit the movement of the mounting block 44. The first metal strip 42 is electrically connected to the motor 22, and the resistance value of the first metal strip 42 on the side of the first slider 43 away from the first electromagnet 45 is connected to the circuit. A first electromagnet 45 is fixedly connected to the inner side of the mounting housing 41. A first magnet 46, which repels the first electromagnet 45, is fixedly connected to one side of the mounting block 44. A first spring 47, which is fixedly connected to the inner wall of the mounting housing 41, is fixedly connected to one side of the mounting block 44. A distance sensor 415 is installed on the lower side of the mounting bracket 25. The distance sensor 415 corresponds to the vertical position of the bracket 27 to detect the height position of the bracket 27. The distance sensor 415 is electrically connected to the first electromagnet 45 and the second electromagnet 412. A temperature sensor 416 is installed on the upper side of the bracket 27. The temperature sensor 416 is electrically connected to the first electromagnet 45 and the third electromagnet 413.

[0023] When the spraying distance is large, i.e., the first electric telescopic rod 26 moves the bracket 27 down a small distance, the distance detected by the distance sensor 415 between the bracket 27 and the upper surface of the bracket 27 is relatively small. This results in a relatively large current in the circuit connected to the distance sensor 415. Through the controller, the repulsive force generated by the first electromagnet 45 on the first magnet 46 can be made relatively large. This causes the mounting block 44 to move the first slider 43 away from the first electromagnet 45 a relatively large distance. The first spring 47 is compressed, resulting in a relatively small resistance value in the circuit connected to the first metal strip 42. Through the controller, the power of the motor 22 can be made relatively large, which can increase the moving speed of the spray gun 28 to shorten the spraying time per unit area, reduce the energy loss of particles in flight, and avoid pitting or thin edges. Conversely, when the spraying distance is small, the moving speed of the spray gun 28 can be made relatively slow to extend the spraying time per unit area, ensuring that the paint fully covers the surface and forms a uniform paint film. When the ambient temperature is high, the temperature detected by the temperature sensor 416 will be higher, resulting in a relatively smaller current in the circuit connected to the temperature sensor 416. This reduces the repulsive effect of the first electromagnet 45 on the first magnet 46, thereby reducing the power of the motor 22 and making the moving speed of the spray gun 28 relatively slower, thus reducing the moving speed at high temperatures. Conversely, the moving speed can be increased when the ambient temperature is low.

[0024] A second metal strip 48 is fixedly connected to the inner side of the mounting housing 41. A second slider 49 is slidably disposed on the outer side of the second metal strip 48. A connecting block 410 is fixedly connected to one side of the second slider 49 and is slidably disposed on the bottom inner side of the mounting housing 41. Correspondingly, a second guide groove adapted to the connecting block 410 is provided at the bottom inner side of the mounting housing 41. The connecting block 410 is slidably disposed along the second guide groove. A second electromagnet 412 and a third electromagnet 413 are fixedly connected to both sides of the connecting block 410 on the mounting housing 41. A second magnet 411 that repels the second electromagnet 412 and the third electromagnet 413 is fixedly connected to the inner side of the connecting block 410. A second spring 414 that is fixedly connected to the inner wall of the mounting housing 41 is fixedly connected to one side of the connecting block 410. The second metal strip 48 is electrically connected to the spray pump 212, and the resistance value of the second metal strip 48 on the side of the second slider 49 away from the second electromagnet 412 is connected to the circuit.

[0025] When the spraying distance is large, the distance sensor 415 can simultaneously increase the repulsive force of the second electromagnet 412 on the second magnet 411, causing the connecting block 410 to move the second slider 49 away from the second electromagnet 412 by a relatively large distance. The second spring 414 is compressed, resulting in a relatively low resistance value of the second metal strip 48 connected to the circuit. Through the controller, the power of the spray pump 212 can be increased, thereby increasing the spraying pressure to enhance the atomization effect, prevent particle stalling or dispersion, and improve the coverage. Thus, when spraying at a long distance, the spraying pressure and the moving speed of the spray gun 28 can be increased to compensate for air resistance and prevent accumulation. Conversely, when the spraying distance is small, the spraying pressure can be relatively low to prevent excessive pressure from causing over-atomization of the paint and particle scattering and waste, and to ensure that the paint particles are uniformly deposited within a short distance, avoiding accumulation or missed spraying. Thus, when spraying at close distance, the spraying pressure can be relatively low and the moving speed of the spray gun 28 can be relatively slow to balance atomization and deposition efficiency. When the ambient temperature is high, the temperature sensor 416 reduces the repulsive force of the third electromagnet 413 on the second magnet 411, and the repulsive force of the second electromagnet 412 on the second magnet 411 reduces the resistance of the second metal strip 48 in the circuit, thereby increasing the power of the spray pump 212 and raising the spraying pressure at high temperatures. Conversely, when the ambient temperature is low, the repulsive force of the third electromagnet 413 on the second magnet 411 is relatively strong, resulting in a relatively high resistance of the second metal strip 48 in the circuit, which in turn reduces the power of the spray pump 212 and lowers the spraying pressure at low temperatures. Therefore, when spraying at a distance, if the ambient temperature is high, the moving speed of the spray gun 28 can be further reduced and the spraying pressure can be further increased to prolong the deposition time and avoid orange peel texture caused by excessively fast surface drying. If the ambient temperature is low, the moving speed of the spray gun 28 can be further increased and the spraying pressure can be further reduced to reduce the influence of viscosity on the spraying. When spraying at a close distance, if the ambient temperature is high, the adjustment of reducing the moving speed and increasing the spraying pressure can prolong the deposition time. If the ambient temperature is low, the adjustment of increasing the moving speed and decreasing the spraying pressure can reduce the deposition resistance. Thus, through the adaptive control adjustment of the control component 4, the quality of aluminum single panel spraying can be improved.
