[0002] The aluminum profile processing process is a complex and delicate process involving multiple key steps, from the preparation of raw materials to the final surface treatment of the finished product, each step has a profound impact on the quality and performance of the product. The main process includes melting, mold design and production, continuous extrusion molding, straightening and alignment, surface treatment and other steps.

[0003] Among them, surface treatment is an important means to improve the corrosion resistance and aesthetics of aluminum profiles. Common surface treatment methods include anodizing, electrophoretic coating, fluorocarbon spraying and electrostatic powder spraying. At present, the aluminum profiles are often hung up and sent to the spraying production line. The spray head sprays the powder of the specified color on the surface of the aluminum profile. Under the action of static electricity, the powder is adsorbed on the surface of the profile to form a layer of powdery coating. Since both sides of the aluminum profile need to be sprayed, two groups of spray rooms need to be designed to spray it when the aluminum profile is continuously conveyed. This will significantly increase the cost and greatly reduce the spraying processing efficiency of the aluminum profile. Summary of the invention

[0007] By adopting the above technical solution, when a workpiece is placed on the first placement table on the conveyor belt at the end of the conveyor frame, motor 1 is started, and motor 1 drives screw rod 1 to rotate, driving the sliding rod to slide on sliding rod 1. During this process, the sliding short rod at the bottom of the connecting rod slides in the linear groove of the slide groove, the rotating cylinder is fixed, and the spray head is aimed at the workpiece for spraying; then motor 1 reverses, screw rod 1 reverses, and the sliding rod retreats to the initial position.

The hypotenuse of the wedge blocks 19 can be intermittently in contact with the hollow cylinder 15. When the workpiece is placed on the first storage table 3, the double-headed screw 9 rotates to drive the connecting blocks 8 on both sides to slide close, driving the circular plate 13. The hollow cylinder 15 and the T-shaped clamping plate 16 are close to each other. When the two circular plates 162 contact the two ends of the workpiece, as the connecting block 8 gets closer, the circular plate 162 drives the hollow cylinder 15 to get closer to the workpiece, and the hollow cylinder 15 begins to contact the inclined surface of the wedge block 19. Then, the hollow cylinder 15 and the T-shaped clamping plate 16 are lifted up together, and rise and slide on the slide rail 14 on the circular plate 13. A friction layer can be provided on the circumferential surface of the circular plate 162, and at this time, the spring 17 is in a compressed state. Therefore, as the circular plate 162 rises, the workpiece is clamped up and away from the fixed plate 18, providing space for the subsequent workpiece to rotate 180°.

[0041] Working principle of an integrated spraying and drying equipment for aluminum profiles:

[0042] The worker can first place the workpieces one by one on the support frame 51. As the drive motor is started, the drive rod 55 rotates, driving the linkage rod 56 to make a circular motion. At this time, the push plate 57 and the linkage rod 56 form a crank mechanism, and the push plate 57 makes a quadrilateral-like motion trajectory to realize the pushing and loading of the workpieces one by one. The setting of the baffle 58 can separate the workpieces one by one, which cooperates with the subsequent individual loading of the workpieces onto each storage table 3.

[0043] After the workpiece is placed on the first storage table 3, the double-headed screw 9 rotates, driving the connecting blocks 8 on both sides to slide closer, driving the circular plate 13, the hollow cylinder 15 and the T-shaped clamping plate 16 to approach each other. When the two circular plates 162 contact the two ends of the workpiece, as the connecting blocks 8 get closer, the circular plate 162 drives the hollow cylinder 15 to get closer to the workpiece, and the hollow cylinder 15 begins to contact the inclined surface of the wedge block 19. Then, the hollow cylinder 15 and the T-shaped clamping plate 16 are lifted up together, and rise and slide on the slide rail 14 on the circular plate 13. A friction layer can be set on the circumferential surface of the circular plate 162, and the spring 17 is in a compressed state at this time. Therefore, as the circular plate 162 rises, the workpiece is clamped and away from the fixed plate 18.

[0044] Start motor 1, which drives screw rod 1 43 to rotate, driving sliding rod 42 to slide on sliding rod 1 44. During this process, the sliding short rod 46 at the bottom of the connecting rod 45 slides in the linear groove 481 of the slide groove 48, the rotating cylinder 44 is fixed, and the nozzle 41 is aimed at the workpiece for spraying; then motor 1 is reversed, screw rod 1 43 is reversed, and sliding rod 42 retreats to the initial position. During this process, the sliding short rod 46 at the bottom of the connecting rod 45 slides in the inclined groove 482 of the slide groove 48, driving the rotating cylinder 44 to rotate. The rotating cylinder 44 is coaxially fixedly connected to the active conveying wheel 6. Therefore, due to the rotation of the active conveying wheel 6, the conveyor belt 2 moves, causing the first storage platform 3 originally close to the end of the conveying frame 1 to move to the middle of the conveying frame 1, and the first storage platform 3 initially located at the end of the conveying frame 1 moves to become the second storage platform 3.

[0045] When the first storage table 3 moves to the second storage table 3, during the process, the driving gear 11 at the end of the rotating rod 10 engages with the outside of the rack 12 during the movement, and the rotating rod 10 rotates 180°. During this process, the circular plate 162 finally drives the workpiece to rotate 180°, and the workpiece on the second storage table 3 is turned over to expose the other side that has not been sprayed, so that it is convenient for the nozzle 41 to spray the other side when it slides next time. By adopting the combination of the spraying mechanism 4, the storage table 3, and the rack 12, both sides of each workpiece can be sprayed continuously without manual reverse operation, which significantly improves the overall spraying efficiency.

[0046] After the workpiece on the second placement table 3 is sprayed, it enters the housing for drying during further transportation by the conveyor belt 2. The spraying and drying can be completed on the entire conveyor rack 1, and the overall efficiency is high.
