The pipe hooking device is installed at the outlet of the discharge passage 22 and comprises a pipe hooking cylinder 261 and a pipe hooking convex block 262, and the pipe hooking cylinder 261 drives the pipe hooking convex block 262 to reciprocate along the direction perpendicular to the discharge passage 22.

Under the force of gravity, the tube moves along the upper surface of the draw tape 12 to the draw tape winding wheel 14. Meanwhile, the second reduction motor 25 drives the transmission chain wheel set 21 to rotate. The pipe moves to the inlet of the discharging channel 22 along with the rotation of the transmission chain wheel set 21 and enters the discharging channel 22.
