When the infrared monitoring sensor 6 detects that one end of the flax raw material is outside the third guide roller 4, the telescopic component 702 drives the power output device 7 to move horizontally in the opposite direction. At the same time, the power output device 7 pushes the active combing plate 8 at the bottom downward through the push-pull rod 701 at the other end. At the same time, the active combing plate 8 drives the driven combing plate 9 upward through the linkage device 10, so that the active combing plate 8 and the driven combing plate 9 at the bottom are close to each other.
