Specifically, a first feeding channel 5 for connecting the first feeding mechanism 3 and the second feeding mechanism 4 is provided on the rotating seat 21, and at least one first positioning component 22 is provided on both sides of the first feeding channel 5. When there is no need to flip the sheet material transported by the first feeding mechanism 3, the driving mechanism 24 drives the rotating seat 21 to rotate until the first feeding channel 5 is at the same horizontal plane as the first feeding mechanism 3 and / or the second feeding mechanism 4.
