ROLLING PRESS MACHINE FOR SECONDARY BATTERY ELECTRODE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a rolling press machine for performing continuous compressing work for a secondary battery electrode material with high working accuracy while preventing the thermal deformation of rolls due to the mechanical friction heat of a bearing part during long-time operation. SOLUTION: The rolling press machine performs continuous compressing work for the continuous sheet-shaped secondary battery electrode material passing between a pair of pressure rolls 11a, 11a. The rolling press machine includes a cooling structure for distributing heat medium in a bearing box 13 which stores and holds a bearing 14 for the pressure rolls, to remove heat from the roll bearing.
