Yarn conveying and guiding mechanism and working method thereof

The invention discloses a yarn conveying and guiding mechanism and a working method thereof.The yarn conveying and guiding mechanism comprises a box body, a cover plate is fixedly connected to the top of the box body, a sliding sleeve penetrates through one side of the top of the cover plate, a sliding rod is slidably connected to the inner surface of the sliding sleeve, and a yarn guiding assembly is fixedly connected to the top of the sliding rod; a position-adjustable mounting plate is arranged in the cover plate, a motor sleeve is fixedly connected to the top of the mounting plate, a rotating mechanism is arranged at the output end of a servo motor, and a screw and a threaded sleeve in the rotating mechanism are matched, so that after the screw rotates out of the interior of the threaded sleeve, an ejector block on the screw can eject a soft belt upwards, and the soft belt is driven to rotate. The two connecting rods move towards the sides close to each other, the height and the narrowness of the rotating
