200mm Roll to Roll Film Unwinding and Rewinding Machine

Product Overview

This 200mm roll-to-roll system is designed for controlled unwinding and rewinding of continuous web materials in laboratory environments. The equipment uses separate unwind and rewind sections and is intended to operate together with a compatible small laboratory twin-roll machine. Its compact configuration supports roll handling where stable web transport, controlled tension, and efficient material recovery are required.

The system is suitable for lithium-ion battery electrode processing, including the rolling of positive and negative electrode sheets. It can also handle optical films, functional films, and other roll-based materials. With a maximum mechanical speed of 1.5 m/min, the unit supports continuous laboratory operation while maintaining a practical scale for process development and small-batch evaluation.

Active rewinding and open-loop constant-torque tension control provide a straightforward method for managing web tension during material collection. A maximum tension of 50 N, three-inch roll cores, and roll diameters up to 200mm support repeatable handling across a range of laboratory materials. The separate modules, modest power requirement, and available 110 VAC customization make the equipment suitable for integration into research workstations.

Key Features

• 200mm Web Width: The 200mm guide roller width accommodates laboratory-scale rolls and provides a defined working width for electrode sheets, optical films, functional films, and similar continuous materials.

• Separate Unwind and Rewind Structure: The unwind and rewind sections are configured as separate modules. This arrangement allows the equipment to be matched with a compatible laboratory twin-roll machine and positioned around the main processing unit according to the workflow.

• Active Rewinding: The rewind section actively collects processed material instead of relying solely on passive material movement. This supports orderly roll formation during continuous operation.

• Open-Loop Constant-Torque Tension Control: Constant-torque control provides a direct and practical approach to web handling. The system supports tension control up to 50 N for laboratory processes that require managed material movement during rolling or film transport.

• Continuous Running Mode: Continuous operation supports sustained web processing rather than intermittent manual handling. This is useful when evaluating electrode calendaring behavior, roll quality, and material consistency across a longer sample length.

• Laboratory Mechanical Speed: A maximum speed of 1.5 m/min gives operators a controlled processing rate appropriate for laboratory-scale development, parameter comparison, and small-batch roll-to-roll trials.

• Three-Inch Roll Core Compatibility: The unwind and rewind shafts are designed for three-inch roll cores, providing a common mounting format for laboratory material rolls and simplifying preparation between experiments.

• Compact Integrated Footprint: The unwind section measures 300mm wide by 250mm deep by 280mm high, while the rewind section measures 300mm wide by 350mm deep by 280mm high. The defined dimensions help users plan bench or equipment-line placement.

• Low Power Requirement: With a rated power of 100W and single-phase 220 VAC operation, the equipment can be incorporated into standard laboratory electrical infrastructure. A 110 VAC version can be customized when required by the installation environment.

Applications

Technical Specifications

The 200mm guide roller width defines the nominal laboratory handling width, while the maximum 200mm roll diameter establishes the supported roll size for both unwinding and rewinding. Users should confirm the actual web thickness, roll construction, core condition, and material properties before selecting process settings for a specific application.

The maximum mechanical speed is 1.5 m/min, and the maximum controlled tension is 50 N. These values provide the principal operating boundaries for laboratory trials. Actual settings should be selected according to the web material, roll quality, required winding condition, and the operating requirements of the connected twin-roll machine.

The unwind and rewind modules have different depths because each section performs a different handling function. The unwind footprint is 300mm wide, 250mm deep, and 280mm high. The rewind footprint is 300mm wide, 350mm deep, and 280mm high. These dimensions should be included when planning the spacing between the roll-handling sections and the associated rolling equipment.

Electrical input is specified as single-phase 220 VAC with a tolerance of ±10%, at either 50Hz or 60Hz. A 110 VAC version can be customized for installations requiring a different standard supply. The 100W power rating supports integration into laboratory work areas where compact equipment and modest electrical demand are important considerations.

Why Choose This Product

• Purpose-Built for Laboratory Roll Handling: The separate unwind and rewind configuration is designed around integration with small laboratory twin-roll processing equipment, making the system appropriate for controlled development workflows rather than general-purpose material transport.

• Consistent Web Management: Active rewinding combined with open-loop constant-torque control provides a defined operating method for collecting continuous materials and managing tension within the 50 N maximum specification.

• Efficient Use of Laboratory Space: Compact, clearly defined module dimensions and a total weight of approximately 35kg simplify installation planning, relocation, and integration into research workstations.

• Broad Material Versatility: The same equipment can support lithium-ion battery electrode sheets, optical films, functional films, and other roll-based materials within its width, diameter, speed, and tension limits.

• Adaptable Electrical Configuration: Standard single-phase 220 VAC input supports common laboratory installations, while customized 110 VAC supply provides additional flexibility for different facility requirements.
