The invention aims to provide a double-roll winding device for rubber sheets. Two winding motors are arranged by arranging an installation plate. The winding motors are connected with winding rolls so as to wind the rubber sheets. A guide roll is used for guiding and controlling tensile force, and then the left winding roll is used for winding first; after winding is completed, a rotation motor rotates by 180 degrees to make the right winding roll rotate to the left side for winding, and discharging is conducted on the winding roll which completes winding at the same time; operation is conducted in this way, and the production efficiency is greatly improved. Besides, the heights of the winding rolls can be adjusted through upward pushing air cylinders, the height of the guide roll can also be adjusted, and adjustment is very convenient. Moreover, winding thickness observation rulers are arranged for observing the winding thickness, and operation is made to be more convenient. The double-roll winding device is simple in structure, easy to operate, capable of efficiently and rapidly winding the rubber sheets and suitable for production.
