Lithium Battery Calender Machine for Electrode Sheet Processing

The Lithium Battery Calender Machine is designed for continuous processing of electrode sheets during electrode production. The equipment uses a parallel multi-row double-roller structure to press the electrode tabs of electrode sheets, helping stretch the electrode tabs and alleviate the breakage rate during continuous coating operations. When used together with a feeding stretching device, the machine can further support the rolling quality of electrode sheets. The equipment is designed for electrode sheet processing applications where stable rolling and controlled stretching are required.

Key Features

One of the main features of the MKYY-1500 Calender Machine is its continuous operating capability. The specified operating speed is ≥120m/min, making the equipment suitable for continuous electrode sheet processing. Its parallel multi-row double-roller configuration provides the rolling structure used to process the electrode tabs of the electrode sheets.

The machine has a maximum rolling force of 10t, while the pressure control accuracy is specified at ≤±0.1T. This controlled rolling force allows the equipment to perform the required pressing operation within the stated technical specifications. The maximum extension rate is 15‰, providing a defined stretching capability for the electrode tabs during processing.

Working Principle and Processing Method

During operation, the electrode sheet passes through the rolling section of the machine. The parallel multi-row double rollers apply pressure to the electrode tabs of the electrode sheet, stretching the tabs as part of the continuous processing process. This stretching operation is intended to alleviate the breakage rate of the electrode tabs.

The machine can also be used together with a feeding stretching device. In this configuration, the feeding and stretching process works together with the rolling operation to improve the rolling quality of the electrode sheets. The equipment therefore focuses on controlled pressing and stretching during continuous electrode sheet processing rather than serving as a general-purpose rolling machine.

Applications

The MKYY-1500 Calender Machine is intended for electrode sheet processing in lithium battery production. Its continuous operating design makes it suitable for electrode coating lines where electrode sheets need to be processed at a specified continuous speed.

The equipment supports electrode sheets with a maximum width of 1400mm. This provides a defined processing range for electrode sheet applications within the specified width. Its combination of continuous operation, controlled rolling force, pressure accuracy, and extension rate makes it suitable for production processes requiring controlled electrode tab stretching and rolling.

Product Benefits

The equipment combines continuous operation with controlled rolling and stretching functions. Its maximum operating speed of ≥120m/min supports continuous electrode sheet processing, while the maximum 10t rolling force provides the specified pressing capability. The pressure control accuracy of ≤±0.1T helps maintain controlled rolling force during operation.

Another benefit is its ability to work with a feeding stretching device. This combined configuration can improve the rolling quality of electrode sheets while helping alleviate electrode tab breakage during the continuous coating process. The maximum 15‰ extension rate and maximum 1400mm electrode sheet width further define the machine's processing capabilities.

Technical Specifications

The main technical specifications of the MKYY-1500 Calender Machine include an operating speed of ≥120m/min, a maximum rolling force of 10t, pressure control accuracy of ≤±0.1T, a maximum extension rate of 15‰, and a maximum electrode sheet width of 1400mm. These specifications provide the primary operating limits for selecting and applying the equipment in an electrode sheet processing line.

Conclusion

The MKYY-1500 Calender Machine is a continuous electrode sheet processing machine designed around parallel multi-row double-roller pressing and stretching. It is used to process electrode tabs during continuous coating, helping alleviate breakage and supporting improved rolling quality when combined with a feeding stretching device. With an operating speed of ≥120m/min, maximum rolling force of 10t, pressure control accuracy of ≤±0.1T, maximum extension rate of 15‰, and maximum electrode sheet width of 1400mm, it provides defined processing capabilities for lithium battery electrode sheet production.
