The moving track box 1 is provided with a servo motor 4 at the side. Two adjusting track boxes 5 are provided below the servo motor 4. Fixed connecting rods 6 are symmetrically fixed to the top surfaces of the two adjusting track boxes 5. The top surface of the fixed connecting rod 6 close to the servo motor 4 is fixed to the bottom surface of the moving track box 1. The top surface of the fixed connecting rod 6 away from the servo motor 4 is in sliding connection with the moving track box 1. The two adjusting track boxes 5 are rotatably connected with supporting rotating rollers 7 at the opposite sides close to the moving track box 1. The output end of the spray head 3 is located above the supporting rotating rollers 7. The ends of the two supporting rotating rollers 7 close to the adjusting track boxes 5 are rotatably connected with connecting plates 9 through bearings. The connecting plates 9 are fixed to the side walls of the adjusting track boxes 5. The ends of the two adjusting track boxes 5 away from the moving track box 1 are rotatably connected with adjustable adjusting rotating rollers 8. The supporting rotating roller 7 close to the servo motor 4 side penetrates through the connecting plate 9 and the adjusting track box 5. The end of the supporting rotating roller 7 penetrating to the outside of the adjusting track box 5 and the output end of the servo motor 4 are both fixed with belt pulleys 10. The two belt pulleys 10 are drivingly connected through a conveying belt 11.

[0023] Specifically, when spraying, the pipeline body 18 is placed between the two adjusting rail boxes 5, so that the support rotating rollers 7 and the adjusting rotating rollers 8 on both sides are located inside the pipeline body 18, and then the adjusting rotating rollers 8 are adjusted so that the adjusting rotating rollers 8 and the connecting plate 9 edges are attached to the inner wall of the connecting plate 9. After attachment, the adjusting rail boxes 5 and the adjusting rotating rollers 8 are fixed. After fixing, the servo motor 4 operates to drive the sprayer 2 and the spray head 3 to move, and at the same time, the support rotating rollers 7 close to the servo motor 4 are driven to rotate through the transmission belt 11 and the belt pulley 10, so as to drive the pipeline body 18 to rotate. At this time, the sprayer 2 and the spray head 3 move to spray the outer surface of the pipeline body 18.

[0024] As an optimization scheme, as shown in Figure 2 and Figure 4 , the two adjusting rail boxes 5 are rotatably connected with adjusting screws 12 inside through bearings. One end of the adjusting screw 12 penetrating to the outside of the adjusting rail box 5 is fixed with a crank 14. The outer sides of the two adjusting screws 12 are threadedly sleeved with adjusting sleeve blocks 13, and the adjusting sleeve blocks 13 are slidably sleeved inside the adjusting rail box 5. One end of the two adjusting rotating rollers 8 close to the adjusting rail box 5 is rotatably connected with another connecting plate 9 through a bearing. One end of the adjusting sleeve block 13 extending to the outside of the adjusting rail box 5 is fixed on the other connecting plate 9.

The inside of the moving rail box 1 is symmetrically provided with a T-shaped sliding groove matched with the sliding block 15 and the connecting screw 16. The width of each fixed clamping block 17 is greater than the width of the T-shaped sliding groove.

[0025] Specifically, when moving the adjusting rail box 5, the fixed clamping block 17 is twisted to release the clamping and fixing of the moving rail box 1. The adjusting rail box 5 is pulled to drive the connecting screw 16 and the sliding block 15 to move inside the sliding groove. After adjustment, the fixed clamping block 17 is twisted to clamp and fix the moving rail box 1 again. When moving the adjusting rotating roller 8, the crank 14 is rotated to drive the adjusting screw 12 to rotate, which in turn drives the adjusting sleeve block 13 connected to the adjusting screw 12 to rotate, so as to adjust the distance between the adjusting rotating roller 8 and the support rotating roller 7.
