[0002] Round balers have become the main machinery for baling and harvesting forage and crop straw. The rope winding mechanism is the core mechanism of the round baler, and it is key to ensuring that the bales produced by the round baler do not fall apart, maintain a regular shape and bale density, and improve baling efficiency. Typically, the rope winding mechanism of a round baler winds the rope in a spiral shape from one side of the bale to the other. Due to the small winding area of ​​a single rope and the suspension of the rope head at the beginning and end of the winding, the rope at the bale end is prone to loosening and falling off, the bale end is prone to expansion, and the bale is prone to falling apart. As a result, it is difficult to guarantee the bale formation rate and density of the bales harvested by the round baler, and the baling quality and efficiency of the round baler are affected.

[0003] Therefore, it is necessary to design a rope winding mechanism for round balers to address the problems of rope head suspension and loosening and bale end expansion in existing technologies, so as to ensure the quality of rope winding, bale density and bale formation rate of the machine during hay and straw baling operations, thereby improving baling quality and production efficiency.
