The plurality of branch pipes 11 are all in a horizontal direction and are arranged in an array in the vertical direction;

[0027] In the initial state, both the moving frame 3 and the moving seat 4 are located at the initial positions and are both away from the bearing plate 2. The limiting plate 5 is in the initial position, the lifting frame 7 is in the initial position, and multiple adjusting rods 8 are all located at the initial positions and are all close to the axis of the lifting frame 7. During use, place the metal pipe vertically on the bearing plate 2. The inner spraying pipe 9 is located inside the metal pipe, and the outer spraying pipe 10 is located outside the metal pipe. Drive the moving frame 3 and the moving seat 4 to slide to the extreme positions and both approach the bearing plate 2.

Through the driving member, drive multiple adjusting rods 8 to synchronously move away from the axis of the lifting frame 7 until multiple adjusting rods 8 are all in contact and overlap with the inner surface of the metal pipe. Through the cooperative action of multiple adjusting rods 8, straighten the metal pipe so that the axis of the metal pipe is aligned with the axis of the bearing plate 2.

Then drive the ring plate 6 to rotate, driving the metal pipe and the bearing plate 2 to rotate together. At the same time, convey paint into the inner spraying pipe 9 and the outer spraying pipe 10. The paint in the inner spraying pipe 9 is sprayed onto the inner surface of the metal pipe through multiple branch pipes 11, and the paint in the outer spraying pipe 10 is sprayed onto the outer surface of the metal pipe through multiple branch pipes 11 to achieve simultaneous spraying of the inner and outer surfaces of the metal pipe. When the spraying is completed, drive the limiting plate 5 to slide upward to the initial position, driving the ring plate 6 to move together away from the top end of the metal pipe. Then drive the moving frame 3 and the moving seat 4 to slide to the initial positions and both move away from the bearing plate 2, and then take the metal pipe away from the bearing plate 2;

[0028] In summary, during use of the present application, the spraying of the outer surface and the inner surface of the metal pipe can be carried out simultaneously to meet the requirement of simultaneous spraying of the inner and outer surfaces of the metal pipe.

The moving frame 3 and the moving seat 4 are respectively in threaded engagement with the forward and reverse threaded sections of the forward and reverse lead screw 12;

[0030] Referring to the above, during use, drive the forward and reverse lead screw 12 to rotate forward. The moving frame 3 and the moving seat 4 respectively slide synchronously in opposite directions due to the forward and reverse thread action and both approach the bearing plate 2. On the contrary, when the spraying is completed, drive the forward and reverse lead screw 12 to rotate reversely. The moving frame 3 and the moving seat 4 respectively slide synchronously in opposite directions due to the forward and reverse thread action and both move away from the bearing plate 2, which is more convenient to use.

[0031] As Figure 2As shown, in some embodiments, a driving rod 13 is rotatably provided on the limit plate 5, the driving rod 13 is in a vertical direction, and the driving rod 13 is connected to the ring plate 6 through a pulley assembly 14.

[0034] Referring to the above, in the initial state, the multiple adjustment rods 8 are all located at the initial positions and are close to the axis of the lifting frame 7, and the multiple protrusions 16 are respectively located at the initial points of the multiple slide grooves 17. When in use, the driving disk 15 is driven to rotate forward, and the multiple protrusions 16 slide to multiple limit points respectively. During this process, the multiple adjustment rods 8 are synchronously moved away from the axis of the lifting frame 7. Conversely, when the spraying is completed, the driving disk 15 is driven to reverse, and the multiple protrusions 16 slide to multiple initial points respectively. During this process, the multiple adjustment rods 8 are synchronously close to the axis of the lifting frame 7, so as to achieve driving the multiple adjustment rods 8 synchronously away from or close to the axis of the lifting frame 7.

[0035] like Figures 4-6 As shown, in some embodiments, an annular groove 18 is provided on the frame 1, and the annular groove 18 is in a horizontal direction. A plurality of support rods 19 are provided on the bearing plate 2, and the support rods 19 are in a vertical direction and fixed on the bearing plate 2.

[0040] Referring to the above, in the initial state, both the cross-moving rod 21 and the outer spraying pipe 10 are located at the initial positions and are both far away from the bearing plate 2, so as to vertically place the metal pipe on the bearing plate 2. During use, the screw rod 22 is driven to rotate forward, and the cross-moving rod 21 slides in the horizontal direction to approach the bearing plate 2 due to the thread action, driving the outer spraying pipe 10 to move together, so as to facilitate subsequent spraying on the outer surface of the metal pipe.

The free end of the corrugated pipe 24 is communicated with the outer spraying pipe 10;

[0042] Referring to the above, during use, the free end of the three-way pipe 23 is communicated with a device for supplying the coating. The coating is conveyed into the three-way pipe 23 through the device for supplying the coating. The coating in the three-way pipe 23 is divided into two streams and respectively enters the inner spraying pipe 9 and the corrugated pipe 24. The coating in the corrugated pipe 24 enters the outer spraying pipe 10, so as to realize simultaneously conveying the coating into the inner spraying pipe 9 and the outer spraying pipe 10, which is more convenient to use. When the outer spraying pipe 10 moves, the corrugated pipe 24 deforms and ensures the normal conveying of the coating.
