Lithium-ion Battery Roll to Roll Battery Electrode Slitting Machine with 15–380mm Width Slitting

Lithium-ion Battery Roll to Roll Battery Electrode Slitting Machine with 15–380mm Width Slitting

I. Equipment Overview

1.1 Function Description

The Slitting Machine is mainly designed for slitting electrode sheets of lithium-ion batteries. As a mature and stable model, it has been widely adopted by our company. It supports a slitting width range of 15–380 mm, features user-friendly operation, and meets diverse slitting process needs. Equipped with a dual-shaft rewinding structure, the machine works as follows: the electrode sheet is mounted on the unwind shaft, passively unwound via the drive roller, and automatically guided. After passing through the slitting blades and iron powder removal unit, the electrode sheet is slit and rewound in line with process requirements. This machine is easy to operate, with simple loading and threading procedures, delivering stable performance and superior slitting outcomes.

1.2 Key Technical Parameters

· Production Capacity: Max mechanical speed is 80 m/min; typical production speed is 0.5–50 m/min with stepless adjustment.

· Rewinding Alignment Accuracy: ≤ ±0.5 mm (assuming good incoming material quality).

· Pass Rate: ≥ 99% (excluding factors such as poor incoming material).

· Utilization Rate: ≥ 95% (excluding material replacement and incoming quality issues).

1.4 Equipment Workflow

The equipment workflow is as follows:  

Web Threading Steps:  

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 to the slitting blades for pre-slitting.  

5. Pass the pre-slit sheet through the dust and iron removal system.  

6. Mount the core sleeve onto the slip shaft.  

7. Tape the electrode sheet to the core sleeve on the slip shaft.  

8. Adjust the sheet tension to the required level.  

9. Switch the web guiding system to automatic mode.  

10. Press the system start button.  

11. The equipment automatically slits the material and rewinds it into rolls.
