Description

Technical Field

[0001] This utility model belongs to the field of aluminum spraying technology, and specifically relates to an aluminum surface spraying device. Background Technology

[0002] With the continuous development of society, aluminum coils and sheets have developed rapidly. Aluminum sheets have low density but high strength, approaching or exceeding that of high-quality steel. They also have good plasticity, can be processed into various profiles, and possess excellent electrical conductivity, thermal conductivity, and corrosion resistance. They are widely used in industry and are a common metal material in home decoration, machinery, and other fields. During the production and processing of aluminum materials, they need to enter a spraying booth to be coated with primer and topcoat. Traditional aluminum spraying processes use single-sided spraying; the aluminum material enters the spraying booth via a conveyor assembly, and the spraying mechanism sprays the surface of the aluminum material.

[0003] Chinese Patent No. 2022208334123 discloses a surface spraying device for precision heat dissipation aluminum material processing. The device includes a spraying box, a first electric telescopic rod, a second electric telescopic rod, a drive motor, and a drive gear. Activating the first and second electric telescopic rods causes them to extend, thereby moving the clamping blocks towards each other to clamp the aluminum material. Activating the drive motor causes the drive gear to rotate, which in turn drives the driven gear, which in turn drives the two clamping mechanisms to rotate, thus rotating the aluminum material. Activating the feeding pump allows the spraying liquid stored in the storage tank to be transported through the first and second conduits to the interior of the horizontal tube, and finally sprayed out from the nozzle to spray the aluminum material clamped between the two clamping mechanisms.

[0004] The above solution has the effect of rapid spraying, but in use, like traditional technology, the spraying components are fixed. During the spraying of aluminum, there are gaps between different nozzles, which can easily create dead corners or overlapping areas during the spraying process, resulting in uneven spraying coverage. Utility Model Content

[0005] To solve the above problems, this utility model provides an aluminum surface spraying device, including a supporting beam plate, a spraying bracket slidably mounted on the supporting beam plate, a reciprocating drive device mounted on the supporting beam plate, the reciprocating drive device being connected to the spraying bracket and driving the spraying bracket to reciprocate on the supporting beam plate, a spray gun fixedly mounted at the bottom of the spraying bracket, an air pipe and a paint pipe connected to the spray gun, a support sleeve fixedly mounted on the side of the spraying bracket, a pipe support rod rotatably mounted on the support sleeve, the pipe support rod having an L-shaped structure, a pipe constraint part connected to the end of the pipe support rod, and the air pipe and paint pipe passing through the pipe constraint part.

[0006] Preferably, the reciprocating drive device includes a driving sprocket and a driven sprocket rotatably disposed at both ends of one side of the supporting crossbeam plate, a chain is provided between the driving sprocket and the driven sprocket, the chain is connected to the spraying bracket, and a drive motor is provided on the other side of the supporting crossbeam plate, the output end of the drive motor is connected to the driving sprocket.

[0007] Preferably, the spraying bracket includes an upper plate, a middle plate, and a lower plate. The middle plate is located between the sides of the upper and lower plates. The upper and lower plates each have a first groove on their opposite sides. A pulley is rotatably installed in each of the two first grooves. The upper and lower sides of the supporting beam plate each have a second groove. The pulley is slidably connected to the second groove. A connecting block is connected to the middle plate and is connected to a chain.

[0008] Preferably, the pipe restraint part is a restraint band, the middle part of the restraint band is connected to the end of the pipe support rod, a male Velcro is provided on the inner side of one end of the restraint band, and a female Velcro is provided on the outer side of the other end of the restraint band.

[0009] Preferably, the support sleeve is also provided with a corrugated pipe, through which the air pipe and paint pipe are arranged.

[0010] The advantages of this utility model are: 1. This solution uses a reciprocating drive device to move the spray gun back and forth on the support beam, enabling the spray gun to move and spray at a stable speed. This improves the uniformity and consistency of the spraying operation and avoids the uneven spraying that is prone to occur in traditional fixed spray guns or manual spraying.

[0011] 2. In this design, the air hose and paint hose rotate around the support sleeve, thereby reducing the sway angle and movement path of the hoses as they move with the spraying bracket. This design effectively reduces the friction stroke of the two hoses during operation, minimizing their contact with surrounding structures, thus reducing wear and aging caused by friction, extending the service life of the hoses, protecting surrounding structures, and further improving the overall durability and stability of the equipment.

[0012] 3. In this design, the upper and lower sliding plates form a double-guide structure by cooperating with the grooves on both sides of the supporting crossbeam plate through pulleys, which enables the spraying bracket to have good guidance and stability during movement, effectively avoiding deviation or jamming, and improving the reliability of the device operation.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Simultaneously, when an component is referred to as "fixed to" or "equipped on" another component, it can be directly on the other component or may have an intervening component present. When an component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present. When an component is referred to as "fixedly connected to" another component, it can be a common fixed connection method such as welding, bolting, or gluing. In short, those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example 1, such as Figure 1-2As shown, an aluminum surface spraying device includes a supporting beam plate 1, which is fixed in a corresponding spraying box. A spraying bracket 2 is slidably mounted on the supporting beam plate 1. A reciprocating drive device is mounted on the supporting beam plate 1 and connected to the spraying bracket 2, driving the spraying bracket 2 to reciprocate on the supporting beam plate 1. A spray gun 3 is fixedly mounted at the bottom of the spraying bracket 2, and an air pipe 4 and a paint pipe 5 are connected to the spray gun 3. The air pipe 4 provides a driving air source for the spray gun, causing it to generate a high-speed airflow. The paint pipe 5 transports liquid paint from the feeding system to the nozzle of the spray gun. Through the reciprocating movement of the spraying bracket 2 on the supporting beam plate 1, the spray gun 3 can move at a uniform speed, effectively improving the spraying coverage and uniformity, and avoiding the uneven spraying problems caused by manual control or different spacing in traditional fixed spraying. The spraying bracket 2 moves automatically through a reciprocating drive device. Combined with the continuous spraying of the spray gun 3, it can significantly improve production efficiency, reduce the frequency of manual operation and labor intensity, and is suitable for batch and standardized spraying operations.

[0022] The reciprocating drive device includes a driving sprocket 9 and a driven sprocket 10 rotatably mounted at both ends of one side of the supporting crossbeam plate 1. A chain 11 is provided between the driving sprocket 9 and the driven sprocket 10, and the chain 11 is connected to the spraying bracket 2. A drive motor 12 is provided on the other side of the supporting crossbeam plate 1, and the output end of the drive motor 12 is connected to the driving sprocket. The chain 11 transmission has the characteristics of strong impact resistance and non-slippage, which can achieve stable reciprocating motion during the spraying process, ensuring that the spraying bracket 2 runs accurately and the spraying is uniform.

[0023] A support sleeve 6 is fixedly installed on the side of the spraying bracket 2. A pipe support rod 7 is rotatably mounted on the support sleeve 6. The pipe support rod 7 has an L-shaped structure, and a pipe restraint part 8 is connected to the end of the pipe support rod 7. The air pipe 4 and the paint pipe 5 pass through the pipe restraint part 8. One end of the pipe support rod 7 is rotatably mounted inside the support sleeve 6 via a bearing. The air hose and the paint hose rotate around one end of the pipe support rod 7 as a rotation axis. As the air hose and the paint hose move with the spraying bracket 2, their own swing amplitude and stroke are significantly reduced. This structure can effectively reduce the movement path of the two hoses, thereby reducing friction and pulling between the hoses and the surrounding structure, and avoiding problems such as wear, aging, and deformation of the hoses due to frequent movement. At the same time, after the air pipe 4 and the paint pipe 5 are set through the pipe restraint part 8, it can effectively avoid problems such as unstable spraying and stress on the spray gun 3 caused by pipe entanglement, swinging, or dragging during the spraying process, thus improving the safety and reliability of the device operation.

[0024] The spraying bracket 2 includes an upper slide plate 13, a middle plate 14, and a lower slide plate 15, with the middle plate 14 located between the sides of the upper slide plate 13 and the lower slide plate 15. Each of the opposite sides of the upper slide plate 13 and the lower slide plate 15 has a first groove 16, and a pulley 17 is rotatably mounted in each of the two first grooves 16. The upper and lower sides of the supporting beam plate 1 have second grooves 18, with the pulleys 17 slidably connected to the second grooves 18. The pulleys 17 on the upper and lower slide plates, embedded in the grooves on the upper and lower sides of the supporting beam plate 1, form a double-sided sliding guide structure, effectively preventing the spraying bracket 2 from shifting or tilting, ensuring stable operation. Simultaneously, the pulleys 17, in conjunction with the grooved guide rails, achieve high positioning accuracy and repeatability, ensuring a consistent trajectory of the spray gun 3 during spraying, thus improving spraying quality and uniformity. A connecting block 19 is connected to the middle plate 14, and the connecting block 19 is connected to a chain 11. This allows the chain 11 to drive the spraying bracket 2 in smooth reciprocating motion, and the connection between the chain 11 and the bracket is firm, preventing it from easily falling off or loosening.

[0025] Combination Figure 3 The pipe restraint part 8 is a restraint strap, the middle of which connects to the end of the pipe support rod 7. The connection method can be adhesive or screw. A male hook 20 is provided on the inner side of one end of the restraint strap, and a female hook 21 is provided on the outer side of the other end. The connection of the male hook 20 and the female hook 21 forms a loop structure. This loop structure firmly binds the pipe to the end of the pipe support rod 7, preventing friction between the pipe and other components during spraying due to shaking or swaying, thus reducing the risk of wear and cracking caused by friction. The restraint strap can be opened and closed using the hook and loop structure, eliminating the need for special tools and facilitating quick disassembly and adjustment, making pipe replacement or maintenance more convenient and efficient.

[0026] Combination Figure 4 The support sleeve 6 is also equipped with a corrugated pipe 22. The air pipe 4 and the paint pipe 5 pass through the corrugated pipe 22. The corrugated pipe 22 is tied to the support sleeve 6 with a rope. The corrugated pipe 22 can further prevent the hose from getting tangled, knotted or excessively bent during the movement of the spraying bracket 2, ensuring the continuity and safety of the spraying operation.
