Rotatable and alternate yarn bobbin disc

The utility model belongs to the technical field of spinning, and particularly relates to a rotatable and alternative spool disc which comprises a workbench, a controller, a placing disc movably arranged on the workbench and used for placing spools, and a plurality of mounting shafts fixed on the placing disc and used for mounting the spools. The driving mechanism is electrically connected with the controller and is used for driving the placing disc to rotate by a certain angle; through the arrangement of the controller and the driving mechanism, when the yarn of the initial yarn drum is pulled away from the yarn drum, an operator controls the placement disc to rotate by a certain angle through the controller, so that the adjacent yarn drums connected end to end of the yarn move to replace the position of the initial yarn drum, and therefore in the follow-up spinning process, the yarn is separated from the initial yarn drum. The yarn pulled away by the spinning machine does not deviate from the yarn drum by a
