Rolling and cutting device

The invention relates to the field of agricultural machinery, in particular to a rolling and cutting device. A first rubbing roller is engaged with a second gear set by the aid of a first gear set, the first gear set comprises at least two first circular arc gears, the second gear set comprises second circular arc gears engaged with the first circular arc gears, materials are conveniently rolled and conveyed and simultaneously can be inputted and rubbed, and passive feeding is changed into active feeding. A second rubbing roller is engaged with a fourth gear set by the aid of a third gear set,the third gear set comprises at least two third circular arc gears, and the fourth gear set comprises fourth circular arc gears engaged with the third circular arc gears. After the materials are inputted and primarily rubbed by the first rubbing roller, the materials enter the second rubbing roller and are sufficiently rubbed. Working efficiency is effectively improved, sufficient rubbing of thematerials can be ensured,
