Title: ELECTRODE PLATE ROLLING SYSTEM CAPABLE OF EXTRUDING AND EXTENDING ELECTRODE PLATE CURRENT COLLECTOR
Abstract:
The present invention provides an electrode plate rolling system capable of extruding and extending an electrode plate current collector. Based on the control of an external PLC control system, the electrode plate rolling system comprises a double-roll mechanism for rolling an electrode plate. An electrode plate conveying mechanism is disposed at the side of the double-roll mechanism in an electrode plate conveying direction, and an electrode plate collection mechanism for collecting the rolled electrode plate is disposed at the other side of the double-roll mechanism. The electrode plate rolling system further comprises at least one current collector extending and extruding mechanism for rolling uncoated areas of the electrode plate. The current collector extending and extruding mechanism is disposed between the electrode plate conveying mechanism and the double-roll mechanism or disposed between the double-roll mechanism and the electrode plate collection mechanism. The present invention has a simple structure and achieves the degree close to the extension of the coated areas of the electrode plate by means of extending the electrode plate current collector, and therefore corrugations can be effectively avoided during the electrode plate rolling process. The present invention is applicable to the rolling of all current electrode plates.
