The control method according to claim 4, wherein the zeroing process is required before the yarn guide (160) returns to zero in step S1, and the zeroing method includes: the coil (470) is electrified, the zeroing device (400) is ejected under the action of magnetic force of mutual repulsion of the magnet (480) and the coil (470), the adjusting rod (230) moves to enable the connecting piece (420) to be propped against the contact (410), when the connecting piece (420) is propped against the contact (410), relative displacement occurs between the buffer seat (450) and the movable core (430) until the two contacts (410) are propped against the connecting piece (420), the central controller (104) memorizes the position of the adjusting rod (230) at the moment through the feedback mechanism (300), the coil (470) stops electrifying, and the movable core (430) is contracted and reset to finish zeroing.
