Example six:

the invention further discloses a reel change cutting line control method, which is applied to the automatic reel change winder in the embodiment and comprises the following steps:

the third driving assembly 53 drives the reel changing plate 5 to rotate anticlockwise, so that the full winding and winding shaft 6 is far away from the yarn discharging assembly 2, at the moment, the cutting knife assembly 9 is not moved to the yarn cutting position, and as shown in fig. 10, the empty winding and winding shaft 6 is close to the yarn discharging assembly 2 and is moved to a yarn breakage preparation station;

the second driving assembly 4 drives the yarn arranging assembly 2 and the yarn clamping seat 64 to move towards the installation vertical plate 1, a yarn clamping groove is formed between the yarn clamping seat 64 and the fixed seat 63 while the reciprocating stroke of the yarn arranging assembly 2 is changed, as shown in fig. 9, the fifth driving assembly 7 drives the cutting knife assembly 9 to move to a yarn cutting station, as shown in fig. 11;

the reel changing plate 5 is driven to rotate, so that the empty reel winding shaft 6 moves to a yarn breaking station, and meanwhile, the yarn discharging assembly 2 is driven to move through the first driving assembly 3, so that the yarn falls into the yarn clamping groove and also falls into the cutting knife assembly 9, as shown in fig. 12;

the second driving component 4 and the fifth driving component 7 are reset, the thread clamping groove is pressed tightly, the yarn arranging component 2 recovers the reciprocating motion stroke interval, and meanwhile, the cutting knife component 9 is reset and cuts off the yarns.

Further, in the winding process of the winding shaft 6, the winding shaft 6 is driven by the fourth driving component 54 to wind the yarn led out from the yarn discharging component 2, and the yarn is spirally wound on the winding drum of the winding shaft 6 by driving the yarn discharging component 2 to do reciprocating linear motion in the interval corresponding to the winding drum on the first mounting seat 11 by the first driving component 3; as the winding diameter of the yarn on the drum increases gradually, the changing reel 5 is driven by the third driving unit 53 to rotate slowly in the counterclockwise direction.
