[0002] Steel pipe is a hollow, long, round steel material, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In order to increase the service life of steel pipes, corrosion-resistant paint is usually sprayed on the surface of the steel pipe to increase the corrosion resistance of the steel pipe.

However, in the actual operation of manual spraying, the paint is easy to come into contact with the human body, which has the defect of damaging the health of the sprayers. At the same time, after the steel pipe is painted, it is necessary to wait for the paint on the surface of the steel pipe to dry before the steel pipe can be stored. The time required for the paint to dry is long, which affects the overall work efficiency. Utility Model Content

A screw rod 17 is rotatably connected in the slide groove 15. The second support seat 4 is provided with a screw hole threadedly connected to the screw rod 17. The output end of the servo motor 16 is fixedly connected to one end of the screw rod 17. The servo motor 16 drives the screw rod 17 to rotate, and the screw rod 17 drives the second support seat 4 to move in the slide groove 15, so that the distance between the first support seat 3 and the second support seat 4 can be freely adjusted, so that steel pipes 8 of different lengths can be adapted, which increases the practicality of the device;

[0025] A first linear motor 9 and a second linear motor 10 are installed on the support frame 2, and a paint spray head 11 is installed on the mover of the first linear motor 9. The paint spray head 11 is driven by the first linear motor 9 to continuously move back and forth along the length direction of the steel pipe 8. In conjunction with the rotation of the steel pipe 8, the paint spray head 11 evenly sprays paint on the surface of the steel pipe 8; a first cylinder 12 is installed on the mover of the second linear motor 10, and a hot air blower 13 is installed at the output end of the first cylinder 12. The paint spray head 11 is located directly above the steel pipe 8, and the air outlet of the hot air blower 13 is aligned with the steel pipe 8. The first cylinder 12 drives the hot air blower 13 to move toward or away from the steel pipe 8, thereby adjusting the optimal drying distance between the air outlet of the hot air blower 13 and the steel pipe 8, and then can adapt to steel pipes 8 of different outer diameters, increasing the practicality of the device, and the second linear motor 10 drives the hot air blower 13 to continuously move back and forth along the length direction of the steel pipe 8, and cooperates with the rotation of the steel pipe 8, so that the hot air blower 13 can dry the paint on the surface of the steel pipe 8, solving the problem that the paint takes a long time to dry, thereby affecting the overall work efficiency;

[0026] An arc-shaped placement plate 19 for placing the steel pipe 8 is installed at the output end of the second cylinder 18. The arc-shaped placement plate 19 is located directly below the steel pipe 8. The arc-shaped placement plate 19 is driven to rise by the second cylinder 18, thereby driving the steel pipe 8 placed in the placement plate 19 to rise, so that the two ends of the steel pipe 8 are respectively aligned with the two conical pressing blocks 7, so that the two conical pressing blocks 7 can press and fix the steel pipe 8; a guide rod 20 is fixedly connected to the bottom of the arc-shaped placement plate 19, and a sliding hole slidably connected to the guide rod 20 is provided on the workbench 1, so as to improve the stability of the arc-shaped placement plate 19 during the rising process and avoid shaking, which may cause the steel pipe 8 in the arc-shaped placement plate 19 to fall.

[0027] Working principle:

[0028] like Figure 1-2As shown, when the spraying device is in use, the steel pipe 8 to be processed is first placed in the arc-shaped placement plate 19, and then the second cylinder 18 is started. The second cylinder 18 drives the arc-shaped placement plate 19 to rise, thereby driving the steel pipe 8 placed in the placement plate 19 to rise. After the two ends of the steel pipe 8 are aligned with the two frustum pressing blocks 7, the second cylinder 18 stops, and the servo motor 16 is started. The servo motor 16 drives the screw 17 to rotate, and the screw 17 will drive the second support seat 4 to move in the slide groove 15, so that the second support seat 4 moves in the direction close to the first support seat 3, and the frustum pressing block 7 at the output end of the rotating motor 6 will be inserted into the steel pipe 8 and push the steel pipe 8 to move in the direction close to the first support seat 3, until the frustum pressing block 7 on the roller 5 is inserted into the end of the steel pipe 8 away from the second support seat 4, so that the two frustum pressing blocks 7 can press and fix the steel pipe 8. After the steel pipe 8 is fixed, the servo motor 16 stops, and the second cylinder 18 starts and drives the arc-shaped placement plate 19 to descend and return to its original height, and then the rotating motor 6 is started The steel pipe 8 is driven to rotate by the rotating motor 6, and then the first linear motor 9 is started. The first linear motor 9 drives the paint spraying head 11 to continuously move back and forth along the length direction of the steel pipe 8. In conjunction with the rotation of the steel pipe 8, the paint spraying head 11 evenly sprays the paint on the surface of the steel pipe 8. After the paint spraying on the surface of the steel pipe 8 is completed, the first linear motor 9 stops, and the paint spraying head 11 stops spraying paint, and the first cylinder 12 is started. The first cylinder 12 drives the hot air blower 13 to move in the direction close to the steel pipe 8. According to visual adjustment After adjusting the distance between the air outlet of the hot air blower 13 and the steel pipe 8, stop the first cylinder 12 and start the second linear motor 10. The second linear motor 10 drives the hot air blower 13 to continuously move back and forth along the length direction of the steel pipe 8. In conjunction with the rotation of the steel pipe 8, the hot air blower 13 can dry the paint on the surface of the steel pipe 8. After the paint on the surface of the steel pipe 8 is dried, stop the rotating motor 6, stop the second linear motor 10 and stop the hot air blower 13 from discharging air, thereby completing the spraying and drying process of the steel pipe 8.
