Tandem Extrusion Lamination Machine (Center Changer)

Product description

Machine brief description

Tandem Extrusion Lamination Machine (Center Changer) uses lamination grade LDPE, LLDPE, PP, EVA, EAA as coating material, mainly designed for paper double side coating, real production speed can reach 280M/Min.

Entire Machine control by PLC, weight more than 50Tons, to ensure machine stable while running at 280M/Min.

Machine Components

1.     Double Station Un-Winder

2.     Auto-Splicer

3.     Automatic-EPC

4.     Traction

5.     Corona Treater

（After treating can increase compounding ability）

1.     Extruder

（With Static Mixer，T-Die Extrusion，ensure stable flow and extrusion coating）

1.     Three Roller Compounding

（Big Diameter Chill Roller, Double Jacket with Inner Spiral flow）

（Different Toughness standard of Silicon roller for different usage）

1.     Trimming Collection

2.     Double Station Winder（Automatic Cutting and Changing）

（PLC control automatic winder, servo motor control cutting and changing, with Auto-Shaft Loader for easy operation）

Highlight

Thickness Automatic Setting

Compounding Part Process and Speed Showing, Screw Rotate and Speed Showing, Extruder & T-Die Temperature Setting and adjusting, entire machine speed adjusting all in Center Control PLC. Pre-Load your process data in Touch Screen（Paper Width, Lamination Thickness）can allow you to work with Synchronization of Compounding Speed, Screw Speed and Thickness of Automatic calculus accurate（For Example: Paper Width 1000mm, lamination thickness 20µm. Set above data and choose Synchronization Calculation On. Then entire machine running you only need to press speed up or speed down button, to make product in precision automatic control, and can make sure thickness remain even while speed down or up）, also you can work with separate control.

Double Side Coating

Instead of coating one side and take paper roll to coat again on the other side by two steps. This way will cause tension change and inevitably cause paper waste (Please note paper after coating is not recyclable). Double Side coating machine can do double side coating in just one process so avoid tension problem and wastage.

Auto-Shaft Changer

High Speed Paper lamination normally use Paper core more than 6”, which is impossible for workers to lift and change every 10 minutes. With Auto-Shaft Changer all those works will be done by Mechanical way and save labor work.

Auto-Splicer

For Super Speed model working speed is too fast, almost every 8-15 minutes will require to change another roll of paper, auto-splicer can change paper rolls automatically in high-speed process with minimum wastage.

Automatic Tension Control

With Linear Positioner and Precision pressure regulating valve) to sense tension, adjust by PLC close loop tension control.

Automatic EPC

Brushless dc push rod drive rectifying control system, Moving distance ±75mm，Motor control by Controller, Acoustic sensors on edge, high precision automatic edge matching.

Product parameters

Please note machine have two different kinds for main High GSM or Low GSM paper:

High GSM: Ground Un-Winder, Friction Winder;

Low GSM: turret Un-Winder, Turret Winder.
