Description

Technical Field

[0002] Copper foil slitting is the process of cutting and separating large rolls of copper foil according to specific sizes, specifications and requirements.

[0003] At present, in the field of copper foil slitting, common slitting devices are mainly composed of driving motors, transmission mechanisms, slitting circular knives and other components. The driving motor drives the slitting circular knives to rotate through the transmission mechanism to perform slitting operations on the copper foil. During the slitting process, due to the lack of self-cleaning function, the copper foil debris accumulated on the blade of the circular knife after a long period of work will cause the blade to become blunt. When slitting copper foil, the blunt blade will make the copper foil cut uneven, burrs and other problems will appear, reducing the quality of the copper foil product. With the accumulation of debris, the rotation resistance of the circular knife increases, which will increase the load of the driving motor, resulting in an increase in the energy consumption of the motor, and also shorten the service life of the motor.
