1.1 Introduction of principle
The rolled cathode/anode electrode is loaded into the roll mechanism, and through the power traction, the electrode is sent to the cutter set which is arranged according to the process specifications for slitting, and the upper and lower rewinding device collects the slit electrode into the roll, and the edge materials are collected by the edge material device. The equipment is assisted by the deviation correction system, tension drive system, dust suction system (including knife suction dust) and other auxiliary precision operation to ensure the stable slitting of the electrode, burr, straightness and other process indicators within the process range.
1.2 Process flow
Transfer carriage Loading the material to unwind reels→èreceived platform→èTraction roller→èSlitting knife setè→Over-roller set →èSeparately up and down sliding differential rewinding axis→èEdge material rewinding→èSet the required electrode tension→èSwitching the electrode alignment system to automatic→èPress the system to start button→èThe equipment automatically slitting and collects in rolls.
