The thread removing and winding equipment adopts a bobbin case and bobbin separated winding working mode. Because the rotating speed of the bobbin is very high in the processes of removing the residual thread from the bobbin and winding the thread, the bobbin case and the bobbin are easy to wear, the bobbin case can be prevented from being worn when the bobbin rotates at a high speed by the winding mode of separating the bobbin case from the bobbin case, and after the thread winding operation is finished, the bobbin case and the bobbin can be automatically assembled and finished, and the thread winding operation on the bobbin case can be finished. When the bobbin is sleeved on the winding main shaft to rotate, the movable ejector head abuts against the bobbin, and the bobbin is prevented from being separated from the winding main shaft when rotating at a high speed; and the movable top head can also be propped against the shuttle peg, and the part of the suture close to the thread head is pressed on the end surface of the shuttle peg, so that the suture and the shuttle peg are prevented from slipping relatively, and the suture can be quickly and smoothly wound on the shuttle peg when the shuttle peg rotates.
Meanwhile, the residual thread removing work of the shuttle peg is considered, and the process is executed without extra equipment and manual operation. Meanwhile, when the bobbin case is separated from the bobbin, the excess thread end wound on the bobbin case is pulled down between the driving wheel and the driven wheel through the separation thread pulling piece, so that the excess thread end can be prevented from being clamped by the excess thread due to the fact that the excess thread end is wound on the bobbin case, the excess thread end can be accurately clamped by the thread removing wheel assembly, and the stability of equipment operation is greatly improved.
