• 本机适应于各类锂电池正负极片的连续轧制分切工艺，采用恒压力、恒辊缝轧制方式，可连续轧制连续或斑马涂布的电池极片，增加材料的致密度。辊压后的极片经过分切机构，可以分切成多条，分别收卷。由恒张力的放卷机构、辊压机、前后拉伸装置、测厚装置、分切、收卷机构、电控系统、伺服液压系统、纠偏装置等组成。

This machine is designed for the continuous calendering and slitting of various lithium-ion battery electrode sheets (both cathode and anode). It adopts constant-pressure and constant roll-gap calendering, enabling continuous processing of both continuous-coated and stripe-coated (zebra-pattern) electrodes to increase material density. After calendering, the electrode passes through the slitting unit, where it is slit into multiple strips and wound separately. The system consists of a constant-tension unwinding unit, calender, front and rear tensioning devices, thickness measurement system, slitting unit, rewinding unit, electrical control system, servo-hydraulic system, and web guiding system.

• 轧辊转速:2-150rpm无级变速可调；

Roll speed: 2–150 rpm, stepless variable speed adjustable.

• 可实现厚度压力或厚度辊缝闭环控制，实现厚度精准控制。

It enables closed-loop control of thickness pressure or roll gap, achieving precise thickness control.

• 有极耳压延及拉升除皱功能,实现大压实比。

It features tab calendering and stretch-wrinkle removal capabilities, achieving a high compaction ratio.

• 来料卷径：1500mm,宽度：1500mm；

Incoming roll diameter: 1500 mm; Width: 1500 mm.

• 极片轧制后厚度一致性:≤±1.5um(与来料有关)，最大轧制力:3200KN。

Electrode thickness uniformity after rolling: ≤ ±1.5 µm (dependent on incoming material); Maximum rolling force: 3200 kN.

• 本机辊压前可以设有切边及除尘除铁机构由电机。主要功能是切除两边不涂布区域及边缘凸起部分，防止涂布部分与非涂布边缘在辊压过程中受力不同导致断带;切刀位置可调，适用范围广。毛刷清理料带上的粉尘由吸尘器吸走。

Prior to the rolling process, this machine can be equipped with edge-trimming, dust removal, and iron removal mechanisms driven by an electric motor. Its primary function is to trim away the uncoated zones and raised edges on both sides of the material strip, thereby preventing strip breakage during rolling—a risk that arises from differential stress between the coated and uncoated edge areas. The position of the cutting blades is adjustable, ensuring broad applicability. A rotating brush cleans dust from the material strip, which is then extracted by a vacuum system.

• 分切通过纠偏、张力控制，箔区料区同时分切、分切刀独立控制，自动分切成需要的规格。

The slitting process utilizes edge guiding and tension control systems to simultaneously slit both the foil and material sections; with independently controlled slitting blades, it automatically cuts the material into the required specifications.

• 设备附属功能可选配极耳压延、多级拉伸、定轴自动换卷、液压辅助换辊等，功能齐全，适配性强。

The equipment offers a range of optional auxiliary functions—including tab calendering, multi-stage stretching, fixed-axis automatic roll changing, and hydraulically assisted roll changing—making it fully featured and highly adaptable.
