Roll-to-Roll Electrode Slitting Machine for Lithium-Ion Battery Sheet Cutting

I. Equipment Overview

1.1 Function Description

The Slitting Machine is primarily used for slitting lithium-ion battery electrode sheets. It is a mature and stable model widely used by our company. The machine supports a slitting width range of 15–380 mm, is user-friendly, and meets various slitting process requirements. It adopts a dual-shaft rewinding structure: the electrode sheet is mounted on the unwind shaft, passively unwound via the drive roller, and guided automatically. After passing through the slitting blades and iron powder removal unit, the electrode sheet is slit and rewound according to process requirements. The machine is easy to operate, with simple loading and threading, stable performance, and excellent slitting results.

1.2 Key Technical Parameters

* Production Capacity: The maximum mechanical speed reaches 80 m/min; the standard production speed ranges from 0.5 to 50 m/min, with stepless adjustment available.

* Rewinding Alignment Precision: ≤ ±0.5 mm (under the condition of good incoming material quality).

* Pass Rate: ≥ 99% (not including impacts from substandard incoming materials).

* Utilization Rate: ≥ 95% (excluding time spent on material replacement and issues related to incoming material quality).

1.4 Equipment Workflow

The equipment workflow is detailed below:
Web Threading Process:
1. Load materials onto the unwind shaft using a transfer cart.
2. Manually thread the electrode sheet through the splicing unit.
3. Guide it through the tension system.
4. Manually feed the sheet into the slitting blades for pre-slitting.
5. Send the pre-slit sheet through the dust and iron removal system.
6. Fit the core sleeve onto the slip shaft.
7. Secure the electrode sheet to the core sleeve on the slip shaft with tape.
8. Set the sheet tension to the required value.
9. Switch the web guiding system to automatic operation.
10. Press the system start button.
11. The equipment then automatically slits the material and rewinds it into rolls.
