[0056] When the internal grinding of the pipe 7 is completed, the clamping mechanism 4 and the grinding mechanism 5 are both separated from the pipe 7, and the transmission motor 32 is started again to drive the transmission block 39 to rotate. At this time, the arc-shaped transmission port 391 on the transmission block 39 close to the unloading mechanism 6 drives the polished pipe 7 to move toward the unloading mechanism 6, and the unloading mechanism 6 unloads the pipe. Specifically, since the transmission block 39 rotates counterclockwise from the second placement plate 212 toward the first placement plate 211, when the transmission block 39 rotates, the arc-shaped transmission port 391 on the transmission block 39 close to the unloading mechanism 6 drives the polished pipe 7 to move toward the guide plate 62. At this time, the pipe 7 on the transmission block 39 moves downward above the guide plate 62, so that the pipe 7 on the transmission block 39 is separated from the transmission block 39 by the action of the guide plate 62, and the pipe 7 separated from the transmission block 39 falls downward from the guide plate 62 into the receiving box 61;

[0057] At the same time, the arc-shaped transmission port 391 on the transmission block 39 near the feeding mechanism 1 drives the next pipe 7 to be polished which falls into the first arc-shaped placement port 24 and the second arc-shaped placement port 25 near the feeding mechanism 1 to enter the first arc-shaped placement port 24 and the second arc-shaped placement port 25 near the unloading mechanism 6, and repeats the above-mentioned polishing process, thereby realizing synchronous unloading and loading, and improving the polishing efficiency.
