[0003] At present, in order to control the burrs on the cross-section of the slitting incision, the design and operating parameters of the slitting module of the slitting machine must be within an appropriate range, that is, within the critical condition range called the "slitting window" in slitting technology, in order to perform normal slitting. The design of the slitting die structure has an extremely important influence on the slitting accuracy, and the die component is an important component for controlling the cross-section burrs of the electrode after slitting. Among them, if the assembly arrangement sequence of the die spacer is not well designed, it will have a serious impact on the cross-section burrs and morphology of the electrode after slitting, thereby causing the electrode to be scrapped due to burrs after slitting. In severe cases, the burrs will pierce the isolation membrane after winding, causing battery short circuit and degradation of battery performance. Therefore, controlling the assembly arrangement sequence of the slitting die spacer is the key control point for controlling the cross-section burrs of the electrode. For this reason, we propose a same-direction knife group structure for improving burrs in a high-speed slitting machine to solve the above problems. Utility Model Content
