The winding machine is a special equipment for the textile industry. As the last process of spinning and the first process of weaving, winding plays the role of a "bridge" linking the past and the future, so it occupies an important position in the textile field; the bobbins with less capacity are connected through winding to make The bobbin with larger capacity can remove the defects on the yarn and improve the quality of the yarn. The existing automatic winder includes a winder body, the winder body is connected with a grooved drum assembly for evenly winding the yarn on the outer wall of the bobbin and a rotating assembly for driving the bobbin to rotate; the grooved drum assembly includes a groove The drum and the power assembly that drives the groove drum to rotate. The groove drum rotates under the action of the power assembly. At this time, under the guide action of the groove drum, the yarn moves along the length direction of the groove drum; at this time, under the action of the rotating assembly, The rotation of the bobbin further realizes the effect that the yarn is wound on the circumferential outer wall of the bobbin; furthermore, the automatic winding of the yarn is completed.

A spinning automatic winder disclosed in Chinese patent CN113879911B has the following working principle: when it is necessary to separate the bobbin from the body of the winder, it is only necessary to lift the crank arm, and at this time, under the action of the guide rod, the adjustment The rod moves to the side close to the clamping rod at the big end, and at this time the limit tube moves to the side away from the wire spool, thereby realizing the separation of the wire spool from the winder body, and thus achieving the effect of being easy to use by the staff.

In the above scheme, there is only one bobbin in the automatic winder, and it is added to the work of the winder body under the action of the large-end clamping rod and the small-end clamping rod. When the bobbin is full of yarn, it needs to The staff manually loosens the large-end clamping rod and the small-end clamping rod, replaces the unused wire spool, and then reuses the large-end clamping rod and the small-end clamping rod to clamp the new wire spool.
