After the insertion is completed, the control system controls the motor 24 to start reverse rotation, and the placement rod 3 drives the inserted yarn tube 4 to reset and rotate upward, thereby reducing certain processes and reducing a certain amount of labor for personnel.
[0037] When personnel are winding cotton yarn on the receiving roller 5, the leading end of the cotton yarn is placed at the clamping port 38, and the electric air pump 44 supplies air to the telescopic air pipe 2 40. The telescopic air pipe 2 40 stretches and pulls the clamping block 39 located at one end inside the receiving roller 5 to move toward the center of the receiving roller 5, so that the leading end of the cotton yarn is clamped at the clamping port 38 by the clamping block 39, and there is no need for personnel to manually stick the leading end of the cotton yarn to the surface of the receiving roller 5 with tape, thereby avoiding the subsequent effort of taking it up.
[0038] When personnel need to take the finished cotton yarn on the receiving roller 5, the control system controls the cylinder 15 to retract, the limit block 16 to move up, and then the torsion spring 2 33 starts to reset, driving the receiving roller 5 to rotate around the central axis of the rotating rod 2 11, so that the end of the receiving roller 5 located in the placement groove 9 moves out, and then the electric air pump 44 is controlled to suck air into the telescopic air pipe 2 40, so that the clamping block 39 no longer clamps the head end of the finished cotton yarn at the clamping port 38, and then the air pump starts to intake air into the telescopic air pipe 1 36, and the telescopic air pipe 1 36 starts to stretch, driving the push block to move, and the push block pushes the finished cotton yarn on the receiving roller 5 to detach, without the need for personnel to manually pull it, further reducing a certain amount of manual labor for personnel.
