Abstract:
A short stress path-type electrode sheet rolling machine and an integrated machine equipment for manufacturing lithium battery electrode sheets, whereby the rolling machine comprises: an upper roller mechanism, a lower roller mechanism, an upper bearing base, a lower bearing base and a roller-gap adjusting mechanism; the upper roller mechanism is connected to the upper bearing base, and the lower roller mechanism is connected to the lower bearing base; the upper bearing base and the lower bearing base are connected by means of a guide shaft; the roller-gap adjusting mechanism is connected to the upper roller mechanism so as to adjust a roller gap between the upper roller mechanism and the lower roller mechanism. The rolling machine has a simpler and more reliable structure, has a shorter stress return path when performing electrode sheet rolling, and may improve rolling precision and rolling quality.
