The bottom box 11 is inlaid with a first conveyor belt 12 and a second conveyor belt 13 located on both sides of the air-drying structure 2. A limited material guide assembly 14 is fixed on the upper side of the bottom box 11. The limited material guide assembly 14 includes a support plate 141. The support plate 141 is telescopically adjusted to adjust the position of a limit plate 142 through a telescopic structure. A guide roller 143 is rotatably connected to the limit plate 142.

[0025] Among them, a control device for controlling the entire equipment is fixed on the front side of the bottom box 11. The telescopic structure in this application is a hydraulic cylinder, which is a prior art. A water guide trough is fixed in the bottom box 11, and a water collecting bucket is provided under the water guide trough to facilitate liquid collection and recycling to avoid water waste.

[0026] Specifically, the limiting plate 142 is rotatably connected to a plurality of guide rollers 143 , and the plurality of guide rollers 143 are evenly spaced and distributed on the limiting plate 142 ;

[0027] In the above scheme, with the assistance of the first conveyor belt 12 on the bottom box 11, the welded pipe is moved between the support plates 141, and with the assistance of the hydraulic cylinder on the support plate 141, the guide roller 143 on the limit plate 142 is driven by the hydraulic rod to move relative to it. Finally, the guide roller 143 is attached to the limit plate 142. When the first conveyor belt 12 drives the welded pipe to move, the guide roller 143 on the limit plate 142 plays the role of limiting and guiding.

[0028] like Figure 1 、 Figure 2 and Figure 3 As shown, an air-drying structure 2 is fixed on the upper unloading structure 1 and is used to air-dry the welded pipe. The air-drying structure 2 includes a support frame 21, on which an air knife assembly 22, a water absorption assembly 23 and a drying assembly 24 are fixed. The drying assembly 24 is located on the right side of the water absorption assembly 23, and the water absorption assembly 23 is located on the right side of the air knife assembly 22. The air knife assembly 22 includes a first circular plate 221, on which an air knife plate 222 is fixed, and on which an air blowing nozzle 223 is embedded.
