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
