Description

Technical Field

[0001] This utility model relates to the field of universal coupling manufacturing technology, and in particular to a high-efficiency spraying device for universal coupling manufacturing. Background Technology

[0002] Universal couplings are mechanical transmission components used for connecting shafts and transmitting torque and motion. During the production process of universal couplings, except for the flange end face, all surfaces of the shaft hub need to be coated with anti-rust primer before painting to adapt to harsh working environments. Common protective paints include epoxy resin paint, polyurethane paint, and acrylic paint.

[0003] Traditional spraying of universal couplings requires frequent manual rotation to complete double-sided spraying, which is complex and prone to uneven spraying. Furthermore, each side needs a long drying time after spraying, resulting in low overall production efficiency. To address these issues, a high-efficiency spraying device for universal coupling production is proposed. Utility Model Content

Windshield curtains 8 are fixedly installed on the left side wall of the spraying box 1 and the right side wall of the drying box 2, respectively, with the two windshield curtains 8 facing the first opening 4 and the second opening 5. The windshield curtains 8 can prevent paint or hot air from escaping from the first opening 4 and the second opening 5 to the greatest extent. A U-shaped base 6 is fixedly mounted between the first opening 4 and the second opening 5, and a [missing information - likely a device or equipment] is fixedly installed inside the U-shaped base 6. The horizontal conveyor 7 has an external PLC control box on its side for real-time control of the horizontal conveyor 7, electric guide rail 10, hydraulic cylinder 13, booster pump 14, and hot air dryer 17. The conveyor belt of the horizontal conveyor 7 is a hollow mesh chain belt. The hollow mesh chain belt of the horizontal conveyor 7 allows the paint residue to pass through and be concentrated in the inclined discharge port 21. On the other hand, it allows the hot air to pass through and act on the arc-shaped guide plate 20. The upper end of the conveyor belt of the horizontal conveyor 7 near the front and rear sides is fixedly connected to the elastic baffle 9. The elastic baffle 9 is made of soft rubber and can prevent the universal coupling from detaching from the horizontal conveyor 7 during conveying or flipping.

[0018] The spraying box 1 is equipped with a spraying mechanism, which includes an electric guide rail 10 fixedly installed on the top surface of the spraying box 1. A matching electric guide seat 11 is slidably connected to the electric guide rail 10.

A mounting bracket 12 is fixedly installed at the lower end of the electric guide seat 11. A hydraulic cylinder 13 is fixedly installed inside the mounting bracket 12. The piston rod of the hydraulic cylinder 13 is vertically downward and passes through the mounting bracket 12. A booster pump is fixedly connected to the lower end of the piston rod of the hydraulic cylinder 13. 14. A paint spray nozzle 15 is connected to the lower end of the booster pump 14. The hydraulic cylinder 13 drives the booster pump 14 and the paint spray nozzle 15 to move vertically up and down, so that the paint spray nozzle 15 can evenly spray the multiple universal couplings on the horizontal conveyor 7. A liquid guiding hose 16 is movably installed through the inner wall of the spray box 1 away from the drying box 2. One end of the liquid guiding hose 16 located inside the spray box 1 is connected to the input end of the booster pump 14. The liquid guiding hose 16 can be adjusted horizontally or vertically with the booster pump 14 and the paint spray nozzle 15.

[0019] The drying chamber 2 is equipped with a drying mechanism, which includes a hot air dryer 17 fixedly installed on the top surface of the drying chamber 2 and a servo tilting motor 18 fixedly installed on the inner right side wall of the drying chamber 2. The air outlet of the hot air dryer 17 is positioned directly opposite the horizontal conveyor 7. The servo tilting motor 18 is positioned near the top surface of the second opening 5. An arc-shaped tilting plate 19 is fixedly installed at the lower end of the drive shaft of the servo tilting motor 18. The lower end of the arc-shaped tilting plate 19 is positioned near the conveyor belt of the horizontal conveyor 7. An arc-shaped guide plate 20 is fixedly connected to the bottom of the U-shaped base 6, which is directly opposite the hot air dryer 17. After the multiple universal couplings that have been painted on one side have completed hot air drying, the horizontal... Conveyor 7 transports multiple horizontally arranged universal couplings to the arc-shaped tilting plate 19. The servo tilting motor 18 drives the arc-shaped tilting plate 19 to simultaneously tilt the multiple horizontally arranged universal couplings. The horizontal conveyor 7 is restarted to transport the tilted universal couplings back to the spray painting box 1 for painting. The tilted and painted universal couplings are then transported back to the drying box 2 for hot air drying. After the multiple universal couplings have been painted and dried on both sides, the servo tilting motor 18 is restarted to drive the arc-shaped tilting plate 19 to rotate until the horizontal conveyor 7 removes the painted and dried universal couplings.

[0020] The U-shaped base 6 is equipped with a waste paint recovery component on the bottom of the spray box 1. The waste paint recovery component includes an inclined discharge port 21 located between the bottom of the spray box 1 and the U-shaped base 6. The inner walls of the inclined discharge port 21 on both sides are inclined. Inclined guide plates 22 are fixedly connected to the upper ends of the U-shaped base 6 on both sides of the inclined discharge port 21. The side walls of the two inclined guide plates 22 are seamlessly welded to the inner wall of the inclined discharge port 21. The front and rear side walls of the two inclined guide plates 22 are seamlessly welded to the front and rear inner walls of the U-shaped base 6, respectively. The two inclined guide plates 22 enable the sprayed waste paint to be concentrated in the inclined discharge port 21. The spray box 1 is equipped with an open collection trough 23 below the inclined discharge port 21. The open collection trough 23 is used to recover the sprayed waste paint that has passed through the inclined discharge port 21.

[0021] In use, this invention utilizes a horizontal conveyor 7 within the U-shaped base 6 to transport multiple universal joints to be painted in a horizontal, linear arrangement to the spray booth 1. An external PLC control box activates the electric guide rail 10 and electric guide seat 11, driving the booster pump 14 and paint nozzle 15 to move horizontally. Simultaneously, a hydraulic cylinder 13 within the mounting bracket 12 drives the booster pump 14 and paint nozzle 15 to move vertically, ensuring that the paint nozzle 15 can evenly spray paint onto the multiple universal joints on the horizontal conveyor 7. The couplings are spray-coated, and the horizontal conveyor 7 transports the single-sided painted universal couplings to the drying chamber 2. The external PLC control box starts the hot air dryer 17 to dry the single-sided painted universal couplings. The hot air is guided through the perforated mesh conveyor belt onto the arc-shaped guide plate 20, which circulates the hot air to the universal couplings, improving the drying effect. After drying, the external PLC control box... The servo-driven tilting motor 18 drives the arc-shaped tilting plate 19 to simultaneously tilt multiple universal couplings arranged horizontally in a row. The horizontal conveyor 7 is then restarted to transport the tilted universal couplings back to the spraying box 1 for painting. After painting, the tilted universal couplings are then transported back to the drying box 2 for hot air drying. Once both sides of the universal couplings have been painted and dried, the servo-driven tilting motor 18 is restarted to drive the arc-shaped tilting plate 19 to rotate until the horizontal conveyor 7 removes the painted and dried universal couplings. This eliminates the need for frequent manual tilting of the universal couplings for painting, reducing labor intensity, ensuring uniform painting, and eliminating the need for long drying times, thus improving overall production efficiency. The excess paint generated during the spraying process is guided by a perforated mesh chain belt and an inclined guide plate 22 into an inclined discharge port 21, allowing the excess paint to be collected in an uncovered collection trough 23 for easy recycling, saving energy and reducing consumption.
