Technical Field

[0001] This utility model relates to the technical field of battery cell production equipment, and in particular to a cutting and stacking integrated machine for balancing the tension of the material strip. Background Technology

[0002] In integrated cell cutting and stacking machines, maintaining stable strip tension is crucial for the smooth operation of unwinding, transporting, slicing, and stacking stages. Irregular variations in strip diameter cylindricity and buffer speeds can cause tension fluctuations.

Since tension fluctuations occur at two points within the machine, these factors can influence or even cancel each other out, preventing traditional tension adjustment mechanisms from achieving optimal responsiveness.
