Overview
This equipment is an automated integrated system designed for multi-layer composite continuous production. It realizes efficient and stable roll-to-roll (R2R) production through dual-station simultaneous unwinding, precise bonding, thermostatic hot pressing and intelligent unwinding processes. It is widely used in multi-layer composite manufacturing in the fields of new energy batteries (such as lithium battery diaphragms), flexible circuits (FPC), medical materials, Encasement films, etc.
Features
1. Double station unwinding: independent control of the active unwinding system, support different materials/thickness of the substrate synchronous discharge.
2. Automatic correction: High Accuracy Photoelectric Sensor （ +/- 1mm) to ensure material alignment accuracy.
3. Hot pressing bonding: temperature/pressure adjustable hot pressing roller group to achieve bubble-free, high-strength interlayer compounding.
4. Tension control: Full closed-loop tension system (PLC + magnetic particle braking) to prevent material tensile deformation.
5. Center winding: constant tension winding, optional surface flattening or center drive mode.
Principle
The equipment releases the material synchronously through the dual-station unwinding system, and ensures the alignment accuracy through the automatic deviation correction device. Then the material enters the hot-pressing bonding area and is compounded under adjustable temperature and pressure. Finally, the central winding system completes the coiling under constant tension to achieve continuous automated production.
Applications
New Energy Batteries (e.g. Lithium Battery Diaphragms), Flexible Circuits (FPC), Medical Materials, Encasement Films
Steps
1. Set parameters: Enter production parameters through the color Touchscreen.
2. Material loading: Install the coil into the dual-station unwinding system.
3. Starting equipment: Starting the system, the material enters the hot pressing zone through correction and tension control.
4. Hot pressing bonding: The material is compounded under the hot pressing roller group.
5. Winding is completed: The composite material is wound through the central winding system.
Notice
• Ensure that the air source pressure is within the range of 0.5-0 MPa.
• Use AC380V three-phase power supply, pay attention to voltage matching.
• Check safety devices such as emergency stop buttons and overload protection before operation.
• Regular maintenance of guide rollers and thermos rollers to maintain cleanliness and accuracy.
• The temperature setting should not exceed 200 ° C to avoid over-limit alarms.
