step three, preparing broken tail yarns: starting a swing air cylinder 77 to drive the driving wheel 741 to rotate in the forward direction, and further drive a synchronous wheel 742 to rotate in the same direction through a synchronous belt 744 wound thereon to control a suction nozzle elbow 71 mounted thereon to rotate, and further drive a yarn suction nozzle 72 connected to the lower part of the suction nozzle elbow 71 to move downwards, and place the sucked broken tail yarn into a yarn groove I435, and then start an air cylinder I531 to drive an upper yarn clamping device 436 to clamp the yarn tail of the broken tail yarn;
step four, the yarn suction nozzle 72 descends to the position of a lower zero sensor 79: starting a swing air cylinder 77 to drive the driving wheel 741 to rotate in the forward direction, and further drive a synchronous wheel 742 to rotate in the same direction through a synchronous belt 744 wound thereon, so as to control a suction nozzle elbow 71 mounted thereon to rotate, and further drive a yarn suction nozzle 72 connected to the lower portion of the suction nozzle elbow 71 to move downwards to a lower zero position sensor 79, wherein the yarn suction nozzle 72 carries an upper broken tail yarn to move downwards and sends the upper broken tail yarn to the inner side of a yarn holding device 6 in front of a splicer 43;
step five, absorbing broken yarn of the bobbin: the large suction nozzle 9 below the splicer 43 is driven by the cylinder to descend to the cheese suction nozzle 8 and align with the cheese suction nozzle 8, and then the bobbin broken yarn is sucked;
step six, preparing broken yarn of the bobbin: then, the large suction nozzle 9 is driven to move upwards by the air cylinder, the sucked bobbin broken yarn is lifted to the front of a yarn groove I434, then an air cylinder I531 is started, and the yarn clamping device 438 is driven to clamp the yarn tail of the bobbin broken yarn;
step seven, yarn splicing: turning on the control switch of the splicing box 433 to form high-speed airflow; then, the cylinder I521 is opened, the upper scissors 437 and the lower scissors 439 are driven to cut off redundant yarns, and then splicing operation is completed;
step eight, returning the yarn suction nozzle 72 to the upper zero position sensor 78: the swing cylinder 77 is activated to drive the driving wheel 741 to rotate in the opposite direction, and then the synchronous wheel 742 is driven to rotate in the same direction by the synchronous belt 744 wound thereon, so as to control the nozzle elbow 71 mounted thereon to rotate, and further drive the yarn suction nozzle 72 connected to the lower portion of the nozzle elbow 71 to return to the upper zero position sensor 78.
In the embodiment, when the yarn suction nozzle 72 cannot reach the lower zero sensor 79, the single spindle gives an alarm, so that a maintainer can find the cause of an accident in a targeted manner, the overhaul is smoothly completed, unnecessary downtime is reduced, and the production efficiency is improved.
