Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to an environmentally friendly spray painting device for aluminum processing. Background Technology

[0002] Environmentally friendly painting equipment for aluminum processing enables environmentally friendly and efficient surface coating of aluminum materials. Through a closed working space, it controls paint mist diffusion and, in conjunction with an adsorption and catalytic purification system, significantly reduces volatile organic compound (VOC) emissions, complying with environmental regulations. Simultaneously, the precise automatic spraying mechanism ensures uniform coating, reduces paint waste, and improves material utilization. The equipment can also recycle and treat painting wastewater and paint residue, reducing the risk of secondary pollution. Furthermore, its stable operating environment guarantees coating quality, enhancing the corrosion resistance and aesthetics of the aluminum, thus balancing environmental compliance with improved production efficiency.

[0003] In the operation of the environmentally friendly painting equipment for aluminum processing, the aluminum material is pre-treated and then enters a closed painting chamber. Automatic spray guns spray according to parameters, and a negative pressure system draws the paint mist into a filter layer, separating solid paint residue. This residue is then decomposed by ultraviolet light or ionized into harmless substances before being discharged. Paint-containing wastewater undergoes sedimentation and flocculation treatment, paint residue is recovered, and clean water is recycled. This closed-loop operation ensures uniform spraying while purifying pollutants through filtration and catalysis, achieving both environmentally friendly and efficient coating.

[0004] In existing technologies, the nozzle diameter of the spray gun in some environmentally friendly painting devices for aluminum processing is fixed. This makes it difficult to flexibly adjust the amount of paint sprayed and the atomization effect when facing different coating thickness requirements or irregularly shaped aluminum materials. This can easily lead to problems such as excessively thick coatings wasting paint or insufficient protection when coatings are too thin. When spraying complex curved surfaces, the fixed nozzle diameter can cause local accumulation or missed spraying, affecting the coating quality. Therefore, an environmentally friendly painting device for aluminum processing is proposed to solve the above problems. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of an environmentally friendly painting device for aluminum processing, comprising a housing 1. The housing 1 provides installation space for all subsequently connected components and reduces paint mist leakage during the painting process, meeting environmental protection requirements. A movable rod 2 is slidably connected to the front side of the housing 1. The movable rod 2 provides a sliding track for the connected components, allowing the connected components to move freely along their length, thereby driving the spray gun 4 to achieve horizontal position adjustment, expanding the working coverage of the spray gun 4 to adapt to the painting needs of aluminum materials of different specifications.

[0036] A sliding block 3 is slidably connected to the outer side of the moving rod 2. The sliding block 3 is a key component connecting the moving rod 2 and the spray gun 4. It can slide on the moving rod 2 to change the horizontal position of the spray gun 4, and it also provides stable support for the spray gun 4, ensuring the stability of the spray gun 4 during movement and painting. The spray gun 4 is fixedly connected to the right side of the sliding block 3. The spray gun 4 is the core component for realizing the painting operation, used to atomize the paint and spray it onto the aluminum surface.

[0037] The spray gun 4 has multiple connecting blocks 5 internally slidingly connected. The connecting blocks 5 connect the rotating ring 6 and the rotating disk 8. When the rotating ring 6 rotates, the power is transmitted to the rotating disk 8 through the connecting blocks 5, so that the two rotate synchronously. The rotating ring 6 is fixedly connected to the opposite side of the multiple connecting blocks 5. The rotating ring 6 can rotate along the direction of the sliding groove of the spray gun 4, and drive the rotating disk 8 to rotate through the connecting blocks 5, thereby triggering subsequent adjustment actions.

[0038] A rotating disk 8 is fixedly connected to one side of multiple connecting blocks 5. The rotating disk 8 rotates under the drive of the connecting blocks 5. The sliding rods 9 inside the disk slide due to centrifugal force or structural action generated by the rotation, thus pushing the slider 11 to move via the triangular block 10. Six sliding rods 9 are slidably connected inside the rotating disk 8. The sliding rods 9 slide within the rotating disk 8, and the triangular blocks 10 connected to their front ends move with them, converting the rotation of the rotating disk 8 into its own linear sliding, providing power for subsequent adjustment of the slider 11's position. Each sliding rod 9 has a triangular block 10 fixedly connected to its front side, connecting the sliding rod 9 and the slider 11. Utilizing the characteristics of the triangular structure, the linear motion of the sliding rod 9 is converted into the sliding of the slider 11 within the groove 24 of the fixed disk 12, achieving a change in the direction of force and pushing the slider 11 to change its position.

[0039] A slider 11 is fixedly connected to the front side of the triangular block 10. The slider 11 slides within the groove 24 of the fixed plate 12. The changes in the position of multiple sliders 11 collectively alter the size of the hexagon formed by the triangular block 10, i.e., the orifice size of the paint spraying outlet of the spray gun 4, thereby adjusting the paint flow rate and range. The front side of the slider 11 is slidably connected to the fixed plate 12, which is fixed inside the spray gun 4. The groove 24 inside the plate provides a sliding track for the slider 11, restricting the direction of movement of the slider 11.

[0040] Reference Figure 1 , Figure 6 , Figure 7 The housing 1 contains a cleaning assembly for removing dust from the aluminum surface. This assembly includes a protective cover 13, the right side of which is fixedly connected to the inner wall of the housing 1. The protective cover 13 provides a mounting platform and protective barrier for internal components such as the motor 14, drive wheel 15, belt 16, driven disc 17, and rotating shaft 18, reducing the corrosion of internal components by external dust and paint mist during painting operations, while ensuring the safety of component operation. The motor 14 is fixedly connected inside the protective cover 13. As one of the power sources for the cleaning assembly, the motor 14 drives the drive wheel 15 to rotate, providing power for the subsequent transmission structure and serving as the core power component for the swinging of the rotating rod 19.

[0041] A drive wheel 15 is fixedly connected to the drive end of motor 14. Driven by motor 14, the drive wheel 15 rotates and transmits power to the driven disc 17 via an outer belt 16. The belt 16 is fitted around the outer side of the drive wheel 15, synchronously transmitting the rotation of the drive wheel 15 to the driven disc 17, thus achieving power transmission between the two and ensuring the stability and continuity of the transmission. The other end of the belt 16 is rotatably connected to the driven disc 17. Driven by the belt 16, the driven disc 17 rotates, and its internally fixed shaft 18 rotates along with it, thereby transmitting power to the shaft 18 and the rotating rod 19 connected to the shaft 18.

[0042] A rotating shaft 18 is fixedly connected inside the driven plate 17. One end of the rotating shaft 18 is fixedly connected to the driven plate 17, and a rotating rod 19 is fixedly attached to the outer side of the other end. The rotating rod 19 rotates under the drive of the driven plate 17, thereby causing the rotating rod 19 to swing, thus adjusting the position of the vacuum head 22 within a certain range. The rotating rod 19 is fixedly connected to the outer side of the rotating shaft 18. The rotating rod 19 connects the rotating shaft 18 and the second motor 20. The rotating rod 19 swings under the drive of the rotating shaft 18, thereby causing the second motor 20 and the vacuum head 22 to change position, expanding the cleaning coverage of the vacuum head 22 to meet the surface cleaning needs of aluminum materials of different sizes.

[0043] A second motor 20 is fixedly connected to the rear side of the rotating rod 19. The second motor 20 provides the rotation angle for the suction head 22, enabling it to better adsorb dust from the aluminum surface. The suction head 22 is fixedly connected to the drive end of the second motor 20. The suction head 22 sucks in the dust from the aluminum surface and discharges it through the external pipe 23 at its bottom. It is the component in the cleaning assembly that performs the dust removal task. The bottom end of the suction head 22 is fixedly connected to the external pipe 23, which is used to transport the dust sucked in by the suction head 22 to an external dust collection device, preventing dust from accumulating inside the outer casing 1 and ensuring cleaning effectiveness and a clean internal environment.

[0044] Reference Figure 2 , Figure 5 , Figure 6 The spray gun 4 has multiple sliding grooves inside. The outer side of the rotating ring 6 is slidably connected to the inside of the sliding grooves. The sliding grooves provide a track for the movement of the rotating ring 6, allowing it to move in a fixed direction and preventing it from deviating. A flexible pawl 7 is rotatably connected to the front side of the rotating ring 6. A serrated groove 26 is formed on the outer side of the spray gun 4. The bottom end of the flexible pawl 7 is slidably connected to the inside of the serrated groove 26. The flexible pawl 7 uses its own elasticity to cooperate with the serrated groove 26 on the outer side of the spray gun 4. When the rotating ring 6 rotates to the appropriate position, the flexible pawl 7 engages in the serrated groove 26, preventing the rotating ring 6 from rotating in the opposite direction, thereby locking the state of the adjustment component and ensuring the stability of the paint spray nozzle diameter.

[0045] The outer side of the rotating disk 8 is rotatably connected to the inside of the spray gun 4. The spray gun 4 provides space for the rotation of the rotating disk 8, ensuring its stability during movement. The front side of the triangular block 10 is slidably connected to the rear side of the fixed disk 12. The front side of the fixed disk 12 is fixedly connected to the inside of the spray gun 4, allowing the fixed disk 12 to work in conjunction with the rotating disk 8 to adjust the orifice diameter. The fixed disk 12 has multiple grooves 24 inside. The outer side of the slider 11 is slidably connected to the inside of the groove 24. Each groove 24 is rectangular, and the multiple grooves 24 are intersected, forming an overall hexagon. The grooves 24 provide direction for the slider 11, allowing it to move along a fixed direction. The inner side of the rotating disk 8 has multiple limiting grooves 25. The outer side of the sliding rod 9 is slidably connected to the inside of the limiting groove 25. The limiting groove 25 is elongated. When the rotating disk 8 moves, it can drive the sliding rod 9 to slide in the limiting groove 25 along a specific direction. The sliding rod 9 is connected to the triangular block 10, allowing the triangular block 10 to move along with the sliding rod 9. The triangular block 10 drives the slider 11 to move together. Under the constraint of the grooves 24, the slider 11 allows the triangular plate to move along the direction of the grooves 24, thereby achieving the adjustment of the aperture size. The outer side of the rotating shaft 18 is rotatably connected to the inside of the protective cover 13, providing support for the movement of the driven disk 17 and the rotating rod 19.

[0046] A protective cover 21 is fixedly connected to the rear side of the rotating rod 19. The protective cover 21 encloses the motor 20, protecting it from dust, debris, and other contaminants that could affect its normal operation and reducing external interference during operation. The outer side of the motor 20 contacts the inside of the protective cover 21, and the driven plate 17 is rotatably connected to the inside of the protective cover 13.

[0047] Working principle: Rotating the rotating ring 6, the rotating ring 6 receives external force and starts to move, driving the rotating disk 8 to rotate through the connecting block 5. The movement of the rotating disk 8 causes multiple sliding rods 9, which are slidably connected inside, to slide in the groove 24 on it. The movement of the sliding rods 9 drives the triangular block 10, which is fixedly connected to its front side, to move. The triangular block 10 slides along the direction of the groove 24 through the slider 11, so that the triangular block 10 can open and close. By adjusting the moving distance of the triangular block 10, the orifice size of the spray gun 4 nozzle can be adjusted. The elastic pawl 7 can slide in the serrated groove 26 on the outside of the spray gun 4. When the movement stops, it is locked between the teeth of the serrated groove 26, which can fix the movement state of the components inside the assembly. This assembly can flexibly adapt to paints of different viscosities and diverse painting needs. The small orifice size can reduce the amount of paint used, reduce the emission of volatile organic compounds, and improve environmental protection. At the same time, it is suitable for spraying fine parts to ensure surface flatness. When the orifice size is increased, the spraying efficiency can be improved to meet the needs of large-area rapid operation without frequent replacement of the spray gun 4.

[0048] When motor 14 is started, the drive wheel 15, which is fixedly connected to the drive end of motor 14, begins to move. The movement of drive wheel 15 drives belt 16 to move, causing the driven disc 17, which is rotatably connected to its other end, to rotate. The rotation of driven disc 17 causes shaft 18 to rotate, thereby driving rotating rod 19 to rotate around shaft 18 as the axis. This allows the suction head 22 to be able to pick up and put away dust on the surface of the aluminum material. When motor 20 is started, motor 20 can drive the suction head 22 to rotate, thereby adjusting the angle of the suction head 22 to clean the surface of the aluminum material. This can remove dust and impurities from the surface of the aluminum material in time before painting, avoiding dust from mixing into the coating and causing defects such as particles and blistering on the paint surface, significantly improving the painting quality and coating adhesion.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
