Solid sodium silicate dissolving roller transmission device

The utility model provides a solid sodium silicate dissolving roller transmission device which comprises middle shafts fixedly connected to the two ends of a roller, bearings are rotationally connected to the middle shafts in a sleeved mode, driven gears are further fixedly connected to the middle shafts in a sleeved mode, and the driven gears are connected with driving gears in a meshed mode. The driven gear is arranged between the bearing and the roller, and the number of teeth of the driven gear is 100-120; the middle shaft between the driven gear and the roller is further sleeved with a bearing column, and the two ends of the bearing column are connected with the driven gear and the roller respectively; the diameter of the bearing column ranges from 45 cm to 55 cm, and the length of the bearing column ranges from 8 cm to 15 cm. In conclusion, operation torque and bending moment are redistributed, the torque is transmitted to the roller, shear stress acts on the connecting position of the bearing column an
