Roller pair pressing and gap accurate adjusting device

The invention provides a roller pair pressing and gap accurate adjusting device. The device comprises a fixed roller, a movable roller and an eccentric shaft which are arranged in parallel, a gap adjusting rail and two connecting rods, the movable roller is arranged along the gap adjusting rail in a sliding mode, the two connecting rods are symmetrically installed at the two ends of the movable roller and the two ends of the eccentric shaft, and the two ends of each connecting rod are hinged to the end of the movable roller and the end of the eccentric shaft respectively. Through the rotationof the eccentric shaft, the two connecting rods can drive the movable roller to be close to or far away from the fixed roller. The roller pair pressing and gap accurate adjusting device has the advantages of being scientific in design, high in adjusting accuracy, stable in roller pair pressing force and simple in structure. 本发明提供了一种辊对压紧及其间隙精确调整装置，包括平行设置的固定辊、活动辊和偏心轴以及间隙调整轨道和两根连杆，所述活动辊沿所述间隙调整轨道滑动设置，两根所述连杆对称安装在所述活动辊和所述偏心轴的两端
