Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to an automated coating equipment for aluminum profiles. Background Technology

[0002] Aluminum profiles are made from aluminum rods through processes such as hot melting and extrusion to obtain aluminum materials with different cross-sectional shapes. The production process of aluminum profiles mainly includes three processes: melting and casting, extrusion, and coloring, among which the coloring process requires the use of spraying equipment.

[0003] Current aluminum profile coating typically uses powder coating, which utilizes a high-voltage electrostatic field to adsorb paint particles onto the workpiece surface. However, excess powder generated during the spraying process falls off and accumulates on a platform beneath the workpiece. Collecting this powder is inconvenient, and if not promptly recycled, the accumulated powder will impact the environment and waste resources.

[0004] Therefore, it is necessary to provide a new automated coating equipment for aluminum profiles to solve the above-mentioned technical problems. Utility Model Content

[0014] This utility model provides an automated coating equipment for aluminum profiles:

[0015] 1. Through the coordinated action of the lifting and reciprocating mechanisms, the spray head can flexibly adjust its position and achieve horizontal reciprocating motion, ensuring that the aluminum profile surface is fully and uniformly coated, significantly improving coating quality and efficiency.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1-3 ,in, Figure 1 A front view schematic diagram of a preferred embodiment of the automated coating equipment for aluminum profiles provided by this utility model; Figure 2 A front sectional view of a preferred embodiment of the automated coating equipment for aluminum profiles provided by this utility model; Figure 3 for Figure 2 The diagram shows an enlarged view of part A.

[0024] The automated coating equipment for aluminum profiles includes: a spray box 1; a collection hopper 2, which is fixedly installed inside the spray box 1, with a buffer pad 6 fixedly installed on its outer wall and fixedly connected to the spray box 1; a guide hopper 3, which is fixedly installed at the open end of the collection hopper 2 extending outside the spray box 1, for collecting excess coating powder; a processing table 4, which is fixedly installed inside the collection hopper 2; a vibrating motor 5, which is fixedly installed on the outer wall of the collection hopper 2, for driving the powder to move towards the guide hopper 3; and a paint cylinder 7, which is fixedly installed on the spray box 1 and has a discharge pipe 8 fixedly installed thereon, with a spraying mechanism at the other end of the discharge pipe 8. Through the cooperation of the collection hopper 2, the guide hopper 3, and the vibrating motor 5, excess powder generated during the spraying process can be effectively collected. The collecting hopper 2 collects the fallen powder, while the vibrating motor 5 drives the powder towards the guide hopper 3. The guide hopper 3 guides the powder, causing it to be discharged in a concentrated manner, solving the problem of inconvenient powder collection and facilitating subsequent powder recycling and reuse. Timely collection of excess coating powder prevents it from scattering randomly within the spray box 1, thus reducing powder pollution to the surrounding environment and meeting environmental protection requirements. The collected powder can be processed and reused, achieving resource recycling, reducing production costs, and avoiding resource waste. The buffer pad 6 reduces vibration transmission between the collecting hopper 2 and the spray box 1, lowering noise during equipment operation, protecting equipment components, improving equipment stability and reliability, and extending the equipment's service life.

[0025] The spraying mechanism includes a fixed frame 9, a nozzle 10, a lifting mechanism, and a reciprocating mechanism. The fixed frame 9 is fixedly installed on the discharge pipe 8, and the nozzle 10 is fixedly installed on the fixed frame 9 and connected to the discharge pipe 8 via a pipe. The lifting mechanism is located on the spraying box 1, and the reciprocating mechanism is located on the fixed frame 9, used to drive the nozzle 10 to perform reciprocating motion to spray the aluminum profile on the processing table 4. The fixed frame 9 provides the mounting base for the nozzle 10. It connects the nozzle 10 to the discharge pipe 8, allowing the nozzle 10 to be stably positioned at the required spraying location, ensuring the smooth progress of the spraying process. Paint powder is transported from the paint cylinder 7 to the nozzle 10 via the discharge pipe 8. The nozzle 10 uses a high-voltage electrostatic field to spray paint particles, causing them to adhere to the surface of the aluminum profile workpiece on the processing table 4, completing the spraying operation. The lifting mechanism's main function is to drive the entire spraying mechanism to move vertically up and down. By adjusting the lifting mechanism, the distance between the nozzle 10 and the aluminum profile workpiece can be changed to adapt to the spraying requirements of aluminum profiles of different sizes and shapes, ensuring the uniformity and quality of the spraying. During the spraying process, the reciprocating mechanism is activated, causing the nozzle 10 to reciprocate in the horizontal direction, thereby spraying the aluminum profile on the processing table 4 comprehensively and evenly, avoiding spraying dead corners and improving the spraying quality.

[0026] The lifting mechanism includes a mounting frame 11, a slide rail 12, a movable frame 13, a movable slot 14, and a telescopic rod 19. The mounting frame 11 is fixedly installed on the inner walls of both sides of the spray box 1. The slide rail 12 is formed on the mounting frame 11. The movable frame 13 is slidably installed in the slide rail 12 and is slidably connected to the discharge pipe 8. The movable slot 14 is fixedly installed on the movable frame 13 and is slidably connected to the fixed frame 9. The telescopic rod 19 is fixedly installed in the mounting frame 11, and its output shaft is fixedly connected to the movable frame 13. The mounting frame 11 provides the mounting foundation and support for the entire lifting mechanism, ensuring that the lifting mechanism can be stably fixed in the spray box 1, creating conditions for the operation of subsequent components. The movable frame 13 can slide up and down in a specific direction within the slide rail 12. The slide rail 12 guides and restricts the movement trajectory of the movable frame 13, ensuring that the movement of the movable frame 13 is smooth and accurate. The movable frame 13 is one of the key components in the lifting mechanism that enables the lifting function. Guided by the slide 12, it moves up and down. Simultaneously, through its sliding connection with the discharge pipe 8, it neither affects the delivery of paint by the discharge pipe 8 nor changes position as the movable frame 13 moves. The movable slot 14 provides sliding space for the fixed frame 9. When the movable frame 13 moves up and down, the fixed frame 9 can make corresponding sliding adjustments within the movable slot 14, thereby driving the spray head 10 to move horizontally to meet different spraying needs. The telescopic rod 19 is the power component that drives the movable frame 13 to slide up and down within the slide 12. Through its own telescopic movement, the telescopic rod 19 provides power to the movable frame 13, enabling it to move within the slide 12 in a set direction and distance, thus realizing the lifting function of the entire spraying mechanism.

[0027] The reciprocating mechanism includes a connecting block 15, a screw 16, and a limiting block 17. The connecting block 15 is fixedly installed on the fixed frame 9 and slidably embedded in the movable groove 14. The screw 16 is rotatably installed in the movable groove 14 and is threadedly connected to the connecting block 15. The limiting block 17 is fixedly installed on the connecting block 15 and slidably connected to the movable groove 14. The rotation of the screw 16 drives the connecting block 15 and the nozzle 10 to perform reciprocating linear motion, enabling the nozzle 10 to spray the aluminum profile comprehensively and evenly in the horizontal direction. This avoids uneven spraying caused by the nozzle 10 being fixed, greatly improving the coating quality of the aluminum profile surface. The sliding connection between the limiting block 17 and the movable groove 14 effectively limits and guides the movement of the connecting block 15, reducing vibration and deviation during movement and ensuring the smoothness and stability of the reciprocating motion of the nozzle 10, thereby ensuring the stability of the spraying quality.

[0028] A guide tube 18 is fixedly installed on the movable frame 13. The guide tube 18 is sleeved on the discharge pipe 8 and is used to assist the discharge pipe 8 in moving with the fixed frame 9. During the spraying process, when the lifting mechanism drives the movable frame 13 to move up and down, the discharge pipe 8 needs to move accordingly to adapt to the position change of the spray head 10. The guide tube 18 plays a key auxiliary role in this process. It can guide the discharge pipe 8 to move along a specific direction, ensuring that the discharge pipe 8 can move smoothly and steadily during the lifting and lowering of the movable frame 13, avoiding problems such as shaking, twisting, or interference with other components. The guide tube 18 restricts the movement trajectory of the discharge pipe 8, reduces the possibility of collision or friction between the discharge pipe 8 and other components, reduces the incidence of equipment failure, extends the service life of the discharge pipe 8 and related components, and reduces equipment maintenance costs and downtime.

[0029] A baffle 20 is fixedly installed on the movable frame 13, and the baffle 20 is located on both sides of the fixed frame 9 to shield the slide chute 12. During the spraying operation, some paint powder sprayed from the nozzle 10 will scatter. The baffle 20 can effectively prevent this scattered paint powder from entering the slide chute 12. This prevents paint powder from accumulating in the slide chute 12 or adhering to the contact surface between the movable frame 13 and the slide chute 12. Accumulation of paint powder may increase the friction of the movable frame 13 sliding in the slide chute 12, causing the movable frame 13 to move poorly or even jam, affecting the normal operation of the lifting mechanism. The shielding effect of the baffle 20 can avoid this situation, protect the components of the lifting mechanism, and extend its service life.

[0030] A sealing door 21 is hinged to the spraying box 1, and the sealing door 21 is correspondingly set with the collection hopper 2 and the processing table 4. During the spraying operation, the sealing door 21, when closed, effectively prevents external dust and impurities from entering the spraying box 1, avoiding these impurities from adhering to the surface of the aluminum profile workpiece or mixing with the paint powder, thereby ensuring the cleanliness of the spraying environment and improving the spraying quality. At the same time, the enclosed environment also helps to reduce the leakage of paint powder and reduce pollution to the surrounding environment. Since the sealing door 21 is correspondingly set with the collection hopper 2 and the processing table 4, the operator can directly operate these two key components after opening the sealing door 21. This facilitates placing the aluminum profile workpiece to be sprayed on the processing table 4, or removing the sprayed workpiece from the processing table 4. The enclosed spraying box 1 can prevent the operator from accidentally coming into contact with the spraying area during equipment operation, reducing the safety hazards that may be caused by paint powder splashing or operating parts of the equipment, and ensuring the personal safety of the operator.

[0031] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0032] The working principle of the automated aluminum profile coating equipment provided by this utility model is as follows:

[0033] In operation, first open the sealing door 21, place the aluminum profile workpiece to be coated on the processing table 4, then close the sealing door 21 and start the equipment. The paint powder in the paint cylinder 7 is transported to the nozzle 10 through the discharge pipe 8. The nozzle 10 uses a high-voltage electrostatic field to spray out paint particles, which are then adsorbed onto the surface of the aluminum profile workpiece on the processing table 4, and the coating operation begins.

[0034] During the spraying process, the telescopic rod 19 of the lifting mechanism is activated, causing the movable frame 13 to slide up and down within the slide groove 12. The up and down movement of the movable frame 13 is slidably connected to the movable groove 14 and the fixed frame 9, causing the spray head 10 to move up and down in the vertical direction, thereby adjusting the distance between the spray head 10 and the aluminum profile workpiece to adapt to the spraying requirements of aluminum profiles of different sizes and shapes, ensuring the uniformity and quality of the spraying.

[0035] Simultaneously, the screw 16 of the reciprocating mechanism begins to rotate under power drive. Since the screw 16 is threadedly connected to the connecting block 15, and the connecting block 15 is limited by the movable groove 14 and can only move linearly, the connecting block 15 will reciprocate linearly along the axis of the screw 16. The reciprocating motion of the connecting block 15 drives the nozzle 10 to reciprocate horizontally through the fixed frame 9, performing comprehensive and uniform spraying on the aluminum profile on the processing table 4, avoiding spraying dead corners and improving spraying quality. The sliding connection between the limiting block 17 and the movable groove 14 plays a good role in limiting and guiding the movement of the connecting block 15, ensuring the smoothness and stability of the reciprocating motion of the nozzle 10.

[0036] During the spraying process, excess coating powder falls into the collection hopper 2. The vibrating motor 5 starts, causing the collection hopper 2 to vibrate, which moves the powder in the collection hopper 2 towards the guide hopper 3. The guide hopper 3 guides the powder, allowing it to be discharged in a concentrated manner, facilitating subsequent recycling and reuse.

[0037] Furthermore, when the lifting mechanism drives the movable frame 13 to move up and down, the guide tube 18 assists the discharge pipe 8 to move with the fixed frame 9, ensuring that the discharge pipe 8 can move smoothly and steadily during the lifting process of the movable frame 13, and avoiding problems such as shaking, twisting, or interference with other components. The baffle 20 effectively prevents scattered paint powder from entering the chute 12, protecting the components of the lifting mechanism and extending its service life.

[0038] After the spraying operation is completed, open the sealing door 21, remove the sprayed aluminum profile workpiece from the processing table 4, and clean and maintain the equipment in order to carry out the next spraying operation.

[0039] Compared with related technologies, the automated coating equipment for aluminum profiles provided by this utility model has the following advantages:

[0040] This invention provides an automated coating equipment for aluminum profiles. Through the coordinated action of a lifting mechanism and a reciprocating mechanism, the spray head can flexibly adjust its position and achieve horizontal reciprocating motion, ensuring that the surface of the aluminum profile is coated comprehensively and evenly, significantly improving coating quality and efficiency. The coordinated design of the collection hopper, guide hopper, and vibrating motor effectively collects excess powder generated during the coating process, facilitating subsequent recycling and reuse. This reduces environmental pollution, lowers production costs, and achieves resource recycling.

[0041] The buffer pad reduces vibration transmission between the collection hopper and the spray box, lowers operating noise, protects equipment components, improves operational stability and reliability, and extends equipment lifespan. The sealed door design facilitates workpiece placement and removal, while the enclosed spraying environment reduces interference from external impurities and powder leakage, ensuring spraying quality and operator safety.
