Description

Technical Field

[0001] This specification relates to one or more embodiments in the field of aluminum single-panel spraying technology, and more particularly to an efficient and uniform spraying processing device for aluminum single panels. Background Technology

[0002] Aluminum single-layer panels are widely used in building exterior walls and interior decoration due to their advantages such as light weight, high strength, corrosion resistance, and good decorative properties. However, existing liquid spraying equipment for aluminum single-layer panels still faces many technical bottlenecks in practical applications, making it difficult to balance spraying uniformity, paint mixing effect, and batch processing efficiency. Specific problems are as follows:

[0003] 1. Poor spraying uniformity and unstable coating quality: Existing technologies mostly adopt fixed nozzle spraying structures (such as the "Spraying machine capable of multi-directional spraying of aluminum panels" in publication number CN113695122B), which achieves multi-directional spraying by adjusting the translation or swing of the nozzle. However, in such equipment, the aluminum panel is in a stationary state, and the distance and angle between the nozzle and the workpiece surface are prone to local deviations, resulting in uneven coating thickness. In particular, the edges and corners of the aluminum panel are prone to missed spraying or accumulation.

[0004] 2. Poor mixing effect of multi-color paint, prone to layering and sedimentation: For multi-color spraying needs, existing equipment mostly uses an external mixing tank for pre-mixing before transporting the mixed paint to the spraying unit. However, the pre-mixed paint is prone to layering and sedimentation during pipeline transportation due to factors such as changes in flow rate and settling, resulting in defects such as color bands and spots on the surface of the aluminum panel after spraying. Summary of the Invention

[0005] In view of this, the purpose of one or more embodiments of this specification is to provide a solution to the problem.

[0006] Specifically, an efficient and uniform spraying processing device for aluminum single panels is provided, including a rotating frame for driving the aluminum single panel to rotate in a ring, a spraying component, and a paint supply component; the bottom of the rotating frame is provided with three supporting base frames, a rotating sleeve is fixed on the rotating frame, an inner cavity for storing paint is opened in the rotating sleeve, and a spraying component communicating with the inner cavity is provided outside the rotating sleeve. The rotating frame drives the rotating sleeve to rotate, and the spraying component cooperates to achieve uniform spraying.

[0007] Preferably, the bottom of the rotating sleeve is fixedly sealed with a base plate, the base plate is provided with a pressurizing device for supplementing paint pressure, and the upper surface of the rotating sleeve is covered with a top cover.

[0008] Preferably, the rotating sleeve has uniformly spaced pipe pre-embedded grooves on its outer periphery, and a high-pressure pipe for conveying high-pressure airflow is fixed in the grooves. The outer wall of the rotating sleeve is uniformly provided with spray nozzles that communicate with the inner cavity.

[0009] Preferably, the nozzle is threaded inside the spray nozzle and is connected to a high-pressure pipe to assist in paint spraying with the help of high-pressure airflow.

[0010] Preferably, the nozzle includes a nozzle connecting pipe, a nozzle outlet, an auxiliary frame, and an air nozzle connected to a high-pressure pipe.

[0011] Preferably, an air pump frame is fixed on the outside of the top cover, and the air pump frame has an air pump mounting groove. The air pump airflow output end installed in the groove is connected to the end of the high-pressure pipe away from the nozzle.

[0012] Preferably, a connecting pipe is rotatably connected at the center of the top of the top cover via a sealed bearing, and the other end of the connecting pipe is connected to the bottom of the paint injection tank of the paint supply assembly.

[0013] Preferably, the paint injection tank is provided with a top cover, and a pressure pump for internal pressurization is installed on the top cover. The side wall of the paint injection tank is provided with a paint inlet pipe.

[0014] Preferably, an auxiliary frame is fixed at the bottom of the paint injection tank, and solenoid valves for controlling paint discharge are provided at the four corners of the bottom of the auxiliary frame.

[0015] Place

[0016] Preferably, the auxiliary frame has a second hole at the top and a first hole at the periphery; the pressurizing device has a pressure pump at the bottom and is made of rubber.

[0017] In view of the above, one or more embodiments of this specification provide an efficient and uniform spraying processing device for aluminum single panels. The one or more embodiments of this specification provide the following beneficial effects:

[0018] 1. Significantly optimized paint mixing effect: By injecting paint at an angle through the paint inlet pipe to form a swirling flow, combined with the first and second holes of the auxiliary frame, efficient and uniform mixing of multi-color paints in the tank is achieved, avoiding the problem of "external premixing + conveying layering" in the existing technology. The uniformity of the mixed paint is improved by more than 60%, and the color difference ΔE value of the aluminum single panel surface after spraying can be controlled within 1.0, and the color matching accuracy meets the needs of high-end decoration scenarios.

[0019] 2. Uniformity and efficiency of rotary spraying are achieved simultaneously: The rotating frame drives the aluminum panel to rotate in a ring, and multiple sets of nozzles form a relative motion of "dynamic rotation of the workpiece + static spraying of the nozzle", so that all areas of the aluminum panel are sprayed evenly, solving the problem of uneven coating of traditional fixed nozzles; at the same time, multiple aluminum panels can be fixed in a ring, and the processing volume per batch is more than 3 times that of existing equipment, with a single shift capacity of up to 600㎡, significantly improving the efficiency of batch spraying.

[0027] Example 1:

[0028] like Figure 1-2As shown, an efficient and uniform spraying processing device for aluminum single panels is provided, including a rotating frame 1, an air pump frame 2, and a paint injection tank 3. The bottom of the base frame 1 is provided with three base frames 11. The rotating frame 1 is provided at the center of the upper surface of the base frame 11.

The bottom of the rotating sleeve 12 is fixedly provided with a base plate 16 for sealing the rotating sleeve 12, and a pressurizing device 17 is provided on the base plate 16. The upper surface of the rotating sleeve 12 is provided with a top cover 15.

[0029] The rotating sleeve 12 is uniformly provided with pipe pre-embedded grooves 13 on its outer periphery. A corresponding high-pressure pipe is fixedly installed in the high-pressure pipe pre-embedded groove 13 to provide high-pressure airflow.

[0031] The connecting pipe 34 is rotatable, which can be adapted to the rotating action of the rotating frame 1 driving the rotating sleeve 12 to rotate, thus avoiding the connecting pipe 34 from getting tangled or damaged due to rotation. The setting of the sealing bearing ensures the smooth rotation of the connecting pipe 34 on the one hand, and achieves the sealing between the top cover 15 and the connecting pipe 34 on the other hand, preventing paint from leaking from the connection and preventing external air from entering and affecting the pressure stability of the inner cavity 18.

[0032] Example 2:

[0033] like Figure 1-2 As shown, an efficient and uniform spraying processing device for aluminum single panels is provided, including a rotating frame 1, an air pump frame 2, and a paint injection tank 3. The bottom of the base frame 1 is provided with three base frames 11. The rotating frame 1 is provided at the center of the upper surface of the base frame 11.

The bottom of the rotating sleeve 12 is fixedly provided with a base plate 16 for sealing the rotating sleeve 12, and a pressurizing device 17 is provided on the base plate 16. The upper surface of the rotating sleeve 12 is provided with a top cover 15.

[0034] The rotating sleeve 12 is uniformly provided with pipe pre-embedded grooves 13 on its outer periphery.

A corresponding spray nozzle 14 is also provided on the outside of the rotating sleeve 12, and a corresponding nozzle is installed in the internal thread of the spray nozzle 14.

[0035] An air pump frame 2 for installing small air pumps is provided outside the top cover 15. Air pump mounting slots 21 are evenly opened on the air pump frame 2, and an appropriate number of air pumps are installed on the air pump mounting slots 21. The airflow output end of the air pump pair is connected to the other end of the high pressure pipe in the high pressure pipe pre-embedded slot 13.

[0036] The connecting pipe 34 is rotatable, which can be adapted to the rotating action of the rotating frame 1 driving the rotating sleeve 12 to rotate, thus avoiding the connecting pipe 34 from getting tangled or damaged due to rotation. The setting of the sealing bearing ensures the smooth rotation of the connecting pipe 34 on the one hand, and achieves the sealing between the top cover 15 and the connecting pipe 34 on the other hand, preventing paint from leaking from the connection and preventing external air from entering and affecting the pressure stability of the inner cavity 18.

[0037] The air pump bracket 2 provides a dedicated mounting carrier for small air pumps, avoiding direct exposure of the air pumps and affecting the overall structural stability of the device; the uniform opening of the air pump mounting slots 21 can ensure the balanced distribution of air pumps and guarantee the consistency of airflow pressure in each high-pressure pipe; the through design of the air pump and the high-pressure pipe realizes the stable delivery of high-pressure airflow, providing a reliable guarantee for the paint atomization assisted by the air nozzle 43.

[0038] The top cover 15 is rotatably connected to the center of the top end of the top cover 15, and the top cover 15 and the connecting pipe 34 are sealed by a sealing bearing.

[0039] The top of the connecting pipe 34 is provided with a paint injection tank 3, the top of the paint injection tank 3 is provided with a top cover 32, and a pressure pump 33 is provided at the center of the upper surface of the top cover 32 for pressurizing the inside.

[0040] An auxiliary frame 36 is installed at the bottom of the paint injection tank 3. Solenoid valves 35 are installed at the four corners of the bottom of the auxiliary frame 36 to effectively discharge the paint while maintaining a certain mixing space during mixing.

[0041] The auxiliary frame 36 has a second hole 38 at the top and a first hole 37 evenly distributed around its perimeter.

[0042] The top of the connecting pipe 34 is provided with a paint injection tank 3, the top of the paint injection tank 3 is provided with a top cover 32, and a pressure pump 33 is provided at the center of the upper surface of the top cover 32 for pressurizing the inside.

[0044] The auxiliary frame 36 has a second hole 38 at the top and a first hole 37 evenly distributed around its perimeter.

[0045] The opening of the first hole 37 and the second hole 38 is a key design to improve the paint mixing effect. The first hole 37, which is evenly distributed on the periphery, allows the paint in different areas of the injection tank 3 to form convection, while the second hole 38 at the top can promote the circulation and mixing of the upper and lower layers of paint. The combination of the two can effectively eliminate dead corners in paint mixing, ensure uniform mixing of multi-color paint, and improve the color consistency of subsequent spraying.

[0046] Example 3:

[0047] like Figure 1-2 As shown, an efficient and uniform spraying processing device for aluminum single panels is provided, including a rotating frame 1, an air pump frame 2, and a paint injection tank 3. The bottom of the base frame 1 is provided with three base frames 11. The rotating frame 1 is provided at the center of the upper surface of the base frame 11. The rotating frame 1 is provided with a rotating sleeve 12, which has an inner cavity 18 for storing paint. The bottom of the rotating sleeve 12 is fixedly provided with a base plate 16 for sealing the rotating sleeve 12, and a pressurizing device 17 is provided on the base plate 16. The upper surface of the rotating sleeve 12 is provided with a top cover 15.

[0048] The rotating sleeve 12 is uniformly provided with pipe pre-embedded grooves 13 on its outer periphery. A corresponding high-pressure pipe is fixedly installed in the high-pressure pipe pre-embedded groove 13 to provide high-pressure airflow. A corresponding spray nozzle 14 is also provided on the outside of the rotating sleeve 12, and a corresponding nozzle is installed in the internal thread of the spray nozzle 14.

[0049] An air pump frame 2 for installing small air pumps is provided outside the top cover 15. Air pump mounting slots 21 are evenly opened on the air pump frame 2, and an appropriate number of air pumps are installed on the air pump mounting slots 21. The airflow output end of the air pump pair is connected to the other end of the high pressure pipe in the high pressure pipe pre-embedded slot 13.

[0050] The connecting pipe 34 is rotatable, which can be adapted to the rotating action of the rotating frame 1 driving the rotating sleeve 12 to rotate, thus avoiding the connecting pipe 34 from getting tangled or damaged due to rotation. The setting of the sealing bearing ensures the smooth rotation of the connecting pipe 34 on the one hand, and achieves the sealing between the top cover 15 and the connecting pipe 34 on the other hand, preventing paint from leaking from the connection and preventing external air from entering and affecting the pressure stability of the inner cavity 18.

[0051] The air pump bracket 2 provides a dedicated mounting carrier for small air pumps, avoiding direct exposure of the air pumps and affecting the overall structural stability of the device; the uniform opening of the air pump mounting slots 21 can ensure the balanced distribution of air pumps and guarantee the consistency of airflow pressure in each high-pressure pipe; the through design of the air pump and the high-pressure pipe realizes the stable delivery of high-pressure airflow, providing a reliable guarantee for the paint atomization assisted by the air nozzle 43.

[0052] The top cover 15 is rotatably connected to the center of the top end of the top cover 15, and the top cover 15 and the connecting pipe 34 are sealed by a sealing bearing.

[0053] The top of the connecting pipe 34 is provided with a paint injection tank 3, the top of the paint injection tank 3 is provided with a top cover 32, and a pressure pump 33 is provided at the center of the upper surface of the top cover 32 for pressurizing the inside.

[0054] An auxiliary frame 36 is installed at the bottom of the paint injection tank 3. Solenoid valves 35 are installed at the four corners of the bottom of the auxiliary frame 36 to effectively discharge the paint while maintaining a certain mixing space during mixing.

[0055] The auxiliary frame 36 has a second hole 38 at the top and a first hole 37 evenly distributed around its perimeter.

[0056] The top of the connecting pipe 34 is provided with a paint injection tank 3, the top of the paint injection tank 3 is provided with a top cover 32, and a pressure pump 33 is provided at the center of the upper surface of the top cover 32 for pressurizing the inside.

[0057] An auxiliary frame 36 is installed at the bottom of the paint injection tank 3. Solenoid valves 35 are installed at the four corners of the bottom of the auxiliary frame 36 to effectively discharge the paint while maintaining a certain mixing space during mixing.

[0058] The auxiliary frame 36 has a second hole 38 at the top and a first hole 37 evenly distributed around its perimeter.

[0059] The opening of the first hole 37 and the second hole 38 is a key design to improve the paint mixing effect. The first hole 37, which is evenly distributed on the periphery, allows the paint in different areas of the injection tank 3 to form convection, while the second hole 38 at the top can promote the circulation and mixing of the upper and lower layers of paint. The combination of the two can effectively eliminate dead corners in paint mixing, ensure uniform mixing of multi-color paint, and improve the color consistency of subsequent spraying.

[0060] The top of the connecting pipe 34 is provided with a paint injection tank 3, the top of the paint injection tank 3 is provided with a top cover 32, and a pressure pump 33 is provided at the center of the upper surface of the top cover 32 for pressurizing the inside.

[0061] The stable pressurization of the pressure pump 33 ensures that the paint maintains a stable pressure during the delivery process, avoiding unstable paint delivery due to pressure fluctuations, which in turn affects the uniformity of the coating thickness. It also improves the effect of the paint in the subsequent atomization process.

[0062] An auxiliary frame 36 is installed at the bottom of the paint injection tank 3. Solenoid valves 35 are installed at the four corners of the bottom of the auxiliary frame 36 to effectively discharge the paint while maintaining a certain mixing space during mixing.

[0063] The auxiliary frame 36 has a second hole 38 at the top and a first hole 37 evenly distributed around its perimeter.

[0064] The uniformly distributed channels allow the paint to flow in multiple directions during the mixing process, breaking the single swirling or convection pattern and further improving the mixing uniformity. At the same time, the channel structure will not generate air bubbles like traditional stirring blades, ensuring the purity of the paint and avoiding pinhole defects on the sprayed surface caused by air bubbles.

[0065] The nozzles are arranged in pairs, with no single row containing eight spray nozzles 14, and in another row containing six spray nozzles 14. Each nozzle consists of a nozzle connecting pipe 4, a nozzle 41, an auxiliary frame 42, and an air nozzle 43.

[0066] The air inlet of the air nozzle 43 is connected to the high-pressure pipe in the high-pressure pipe pre-embedded groove 13 through a pipe.

[0067] This structure creates a complete delivery path for high-pressure airflow, enabling the high-pressure airflow generated by the air pump to be delivered accurately and stably to the air nozzle 43. The cooperation between the air nozzle 43 and the nozzle 41 makes the atomized paint particles smaller and more evenly distributed, improving the fineness of the coating. At the same time, the high-pressure airflow can also enhance the adhesion of the paint particles and improve the bonding strength between the coating and the surface of the aluminum panel.

[0068] The pressurizing device 17 is equipped with a pressure pump at its bottom and is made of rubber.

[0069] The pressure pump provides pressurizing power to the pressurizing device 17. The rubber material has good elasticity and oil resistance. On the one hand, it can achieve flexible compression of the inner cavity 18 space through elastic deformation, and accurately compensate for the pressure loss when the amount of paint decreases.

[0070] Working principle: During use, the aluminum single-panel workpiece to be sprayed is fixed in a ring around the outer perimeter of the rotating frame 1, and sufficient paint is injected into the two paint inlet pipes 31. Different colors are injected and mixed as needed. When different colors are needed, the injection through the inclined pipe achieves an internal swirling effect, which greatly increases the mixing effect. After rotation, the mixing effect is achieved through the cooperation of the first hole 37 and the second hole 38. The pressure pump 33 pressurizes the interior to maintain an increased internal pressure. When the mixed paint enters the inner cavity 18 and sufficient amount is injected, the paint is sprayed. During the air spraying process, the rotating frame 1 rotates and sprays evenly. During the spraying process, the paint is sprayed through the nozzle, and effective air spraying is achieved under the action of the air pump frame 2. During the spraying process, when the amount of paint inside decreases, the pressure device 17 is pressurized to achieve the effect of uniform paint application.
