The interior of the gear ring cavity 41 is hollow and is configured as an air cavity. A plurality of bristles 49 are fixedly connected to the inner wall of the gear ring cavity 41. The bristles 49 fit into the surface of the pipe body 7 and can brush the impurities of the pipe body 7. A plurality of through holes 47 are opened through the inner wall of the gear ring cavity 41. A fixing ring 42 is rotatably connected to one side of the gear ring cavity 41.

[0029] The specific working method is: when in use, first place the pipeline body 7 on the lifting arc block 21, then, the cylinder 11 is controlled to move through the controller on the rounding machine body 1, the cylinder 11 rises, and drives the limit contact head 12 to slide inside the long circular groove 9. During the sliding process, the sliding vertical plate 8 can be driven to slide inside the limit groove 16. During the process of the sliding vertical plate 8 driven by the cylinder 11 to slide, the two rectangular lifting blocks 19 will be driven to rise through the connecting bent rod 13, so as to realize the lifting of the pipeline body 7, and the sliding vertical plate 8 drives the rack 1 28 to move, and then drives the rotation of the gear body 30. The rotation of the gear body 30 will drive the rotation of the bevel gear 1 34. The rotation of the bevel gear 1 34 can synchronously drive the bevel gear 2 35 and the bevel gear 3 36 to rotate in the opposite direction, so that the rotating sleeve 37 can drive the clamping jaw 1 31 and the clamping jaw 2 32 to open. After fully opening, the pipeline body 7 is lifted inside the clamping jaw 1 31 and the clamping jaw 2 32; At this time, the limit contact head 12 squeezes one of the pressure sensors 10 at the highest point of the long circular groove 9, and the pressure sensor 10 can transmit the signal to the two electric control valves 23 through the controller. Closing the electric control valves 23 can close the oil circuit inside the rectangular tube 18. Then, the cylinder 11 descends, which can drive the limit contact head 12 to descend, thereby driving the sliding vertical plate 8 to reset. At the same time as the sliding vertical plate 8 is reset, the rack 1 28 is reset to drive the gear body 30 to reverse, so as to achieve the reset between the clamping jaw 1 31 and the clamping jaw 2 32 to clamp the pipeline body 7. When the limit contact head 12 moves to the lowest point of the long circular groove 9, it squeezes another pressure sensor 10. The pressure sensor 10 can transmit the signal to the two electric control valves 23 through the controller to open the electric control valves 23. At this time, the oil circuit is connected, and the two rectangular lifting blocks 19 can be reset under the reset of the tension spring 20, and the hydraulic oil inside the rectangular tube 18 is squeezed into the oil storage cylinder 24. After the clamping jaws 1 31 and 2 32 are reset to center and clamp the pipe body 7, the pipe body 7 can be transported by the provided conveying rollers 33. During the transportation, the hydraulic cylinder 3 rises, which can drive the rack 2 40 to move, and then drive the gear ring cavity 41 to rotate, so that the bristles 49 inside the gear ring cavity 41 can clean the impurities on the surface of the pipe body 7. During the cleaning, the hydraulic cylinder 3 drives the piston rod 44 to rise synchronously, and the air inside the cylinder 45 can be introduced into the gear ring cavity 41 through the air outlet pipe 43, and then blown out through the through hole 47, so that the impurities on the surface of the pipe body 7 can be blown away and the bristles 49 can be cleaned at the same time. The pipe body 7 after cleaning the impurities can enter the rounding machine for rounding. The rounded pipe body 7 can be assisted by the moving mechanism 51 for movement and delivery, thereby completing the rounding work.
