[0002] Due to the high power storage capacity of lithium batteries, they are widely used in life. Lithium batteries are made by processing and combining metallic lithium and manganese dioxide. Metallic lithium is used as the negative electrode. In order to make the electrode pieces the same size, the lithium metal plate is segmented using the cutting knife of a slitting machine.
[0003] In the prior art, when the existing lithium battery production slitting machine is in use, as the lithium metal plates wound on the winding roller and the unwinding roller increase or decrease, one side of the lithium metal plate becomes higher and the other side becomes lower during winding, resulting in the lithium metal plate being not horizontal and one side being separated from the upper surface of the slitting plate, thereby affecting the stability of the lithium metal plate at the cutting and slitting. Moreover, when the lithium metal plate is unwinding, there is a lack of guidance, which is prone to deviation, thereby affecting the quality of the lithium metal plate slitting. Now, a lithium battery production slitting machine is urgently needed to solve the above problems. Utility Model Content
