The transmission set comprises a third bevel gear 8, a fourth bevel gear 9, a fifth bevel gear 13 and a driven shaft 10, wherein the fifth bevel gear 13 is coaxially connected to the driving shaft 2, the fifth bevel gear 13 and the third bevel gear 8 are vertically meshed, and the third bevel gear 8 and the fourth bevel gear 9 are coaxially connected to the driven shaft 10; the first bevel gear 6 and the second bevel gear 7 are respectively positioned at two sides of the fourth bevel gear 9.
The distance between the first bevel gear 6 and the second bevel gear 7 is larger than the diameter of the fourth bevel gear 9.
And limiting bearings 11 are arranged on two sides of the first bevel gear 6 and the second bevel gear 7.
When the yarn feeder operates, one end of the screw 12 close to the yarn feeding roller 3 is attached to the cambered surface of the yarn feeding roller 3.
When the first bevel gear 6 is meshed with the fourth bevel gear 9, the belt pulley 4 rotates positively to realize the unidirectional rotation of the wire feeding roller 3; when the second bevel gear 7 is engaged with the fourth bevel gear 9, the belt pulley 4 rotates reversely to realize the unidirectional rotation of the wire feeding roller 3.
The method comprises the following specific operation steps: before needing to move and carrying out yarn conveying, the turning direction of the yarn feeding roller 3 needs to be adjusted, so that the yarn feeding roller 3 feeds yarns in a single direction no matter the belt pulley 4 rotates reversely or rotates positively, and the specific adjusting mode is as follows: the sliding cover block 5 is provided with an opening, so that the first bevel gear 6 and the second bevel gear 7 are exposed, and the screw 12 at the threaded hole 61 is aligned with the opening, and if the screw 12 is not opposite to the opening, the yarn feeder can be rotated properly. Then, the screw 12 is unscrewed by a tool such as a screw 12 cutter, but the screw 12 is not detached from the threaded hole 61, and the part of the screw 12 extending out of the threaded hole 61 can be used as an adjusting rod, so that the screw 12 is transversely moved to achieve the purpose that the first bevel gear 6 or the second bevel gear 7 is engaged with the fourth bevel gear 9, when the belt pulley 4 on the yarn feeder is rotated in the forward direction, the first bevel gear 6 is engaged with the fourth bevel gear 9, and when the belt pulley 4 is rotated in the forward direction, the yarn feeding roller 3 is also rotated in the forward direction.
