• 本機適應於各類鋰電池正負極片的連續軋製分切工藝，采用恒壓力、恒輥縫軋製方式，可連續軋製連續或斑馬塗布的電池極片，增加材料的致密度。輥壓後的極片經過分切機構，可以分切成多條，分別收卷。由恒張力的放卷機構、輥壓機、前後拉伸裝置、測厚裝置、分切、收卷機構、電控係統、伺服液壓係統、糾偏裝置等組成。

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.

• 軋輥轉速:2-150rpm無級變速可調；

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

• 可實現厚度壓力或厚度輥縫閉環控製，實現厚度精準控製。

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

• 有極耳壓延及拉升除皺功能,實現大壓實比。

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

• 來料卷徑：1500mm,寬度：1500mm；

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

• 極片軋製後厚度一致性:≤±1.5um(與來料有關)，最大軋製力:3200KN。

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

• 本機輥壓前可以設有切邊及除塵除鐵機構由電機。主要功能是切除兩邊不塗布區域及邊緣凸起部分，防止塗布部分與非塗布邊緣在輥壓過程中受力不同導致斷帶;切刀位置可調，適用範圍廣。毛刷清理料帶上的粉塵由吸塵器吸走。

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.

• 分切通過糾偏、張力控製，箔區料區同時分切、分切刀獨立控製，自動分切成需要的規格。

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.

• 設備附屬功能可選配極耳壓延、多級拉伸、定軸自動換卷、液壓輔助換輥等，功能齊全，適配性強。

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.
