Product Description

Gws-300 Center Sealing Machine

1. Main Technical Parameter: 

Width of Unwinding
Diameter of Unwinding
Diameter of Rewinding
Max speed of Working
Max speed of Machine
Power of Whole Machine
Voltage of Whole Machine
Dimension of Whole Machine
Weight of Whole Machine

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 × 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.
