Vacuum Suction Roller for Film Lamination
Vacuum Suction Roller Application:
It is suitable for strip films (such as lithium battery strength, lithium battery positive tension, copper foil, aluminum foil, tape, protective film, tumor film, automobile explosion-proof film, etc .), among which the traction power roller under tension control requirements.
Vacuum Suction Roller The main advantage:
●Traction arm tension isolation, the isolation value can be adjusted by the tension and negative pressure value;
●The material exerts pressure and is squeezed by the rollers to generate a large traction force;
● Achieve single-sided contact with adhesive materials, effectively avoiding damage to the adhesive surface;
●Stabilize the position of the material and prevent the material from slipping on the traction roller;
●Connect the traction force with the tension difference, and the front output tension can be zero;
●Be able to concentrate and meet the needs of special occasions;
Vacuum Suction Roller theoretical analysis:
Patm-atmospheric pressure Pavc-negative air pressure
1. Drive support shaft: reaction force support and air extraction function of roller surface traction and rotation;
2. Traction force is used on the roller surface;
3. The input tension is large and the output tension is small, achieving torque traction.
4. Torque realization principle:
T=(Patm- Pvac) *S *f*R*K
