2. Performance and Characteristics:
Model GWS-300 High Speed Center sealing machine is specially used in folding
film material (such as PET, PVC. etc) into reel-shaped packing material.
1. The main motor adopt converter motor, it use vector converter to make it
close-circle control, high precision speed, and low speed and high speed
equably gluing.
2.Tension control of unwinding adopts 2.5Kg magnetic powder brake(brand KORTIS).With
the tolerance of ±0.5kg
3.Automatic Tension control, accelerate and decelerate, which tension can be make up
by inertance.
4.Epc adopts(Brand Techmac from USA). Its tolerance can reach ±0.1mm.The max
tracking speed is 25mm/s.The ranger of left to right pushing is ±70mm
5.Unwinding adopt 3 inch(74mm) air shaft.
6.The traction steel roller(pressure roller), diameter and width is: 90mm, 320mm,
which surface is chromium plated and fine machining.
7.Traction rubber roller, diameter and width is: 90mm, 320mm, which material is
polyurethane rubber.
8.Steel roller clutch adopt pneumatic cylinder at both side for working at same time ,
cylinder diameter: 50mm x 20mm stroke, pressure can be adjusted arbitrarily.
9.Traction rubber roller is independent, synchronous pass, vector inverter motor
drive.
10. Rewinding roller adopts 3 inch(74mm) batten type air shaft.
11. Rewinding part use independent motor and magnetic power to control the
tesion, magnetic power has lower heating, and realize stable and samll tension
control.
12. Rewinding conicity tension(semidiameter- tension curve; speed- tension curve)
13.When reach the rewinding setted length or diameter, it stops automatic.
When reach the unwinding smallest diameter, it stops automatic.
14.The gluing part coated with solenoid valve needle valve and equipped with
flow metering pump. This pump control the glue flow automatically. It send out
glue and close the glue system when start or stop
15. In the middle of whole machine with the excessive guide roll , guide roller is
aluminum alloy materials, guided roller with hard anodized surface (same as brown
guide roller). When guide roll move, the static balance is ± 0.4g; coating specification:
Φ30mm-Φ300mm; gluing maximal speed is 300m/min; gassho accuracy: ± 0.3mm.
