This machine use paper/plastic film/woven fabric/aluminium foil as base material,through extrusion coating film to make two-layer/three-layer(sandwich composite) or multi-layer compound products at one time.Compared with SJFM-A series, this machine add a second unwinding frame, to achieve the compounding function.
Widely used in food packing fields, such as: snack bags/paper cup/drink cup/yogurt cup/medical packing/nonwoven bag and so on.
1.Double work-station bearing feeding frame， non-stop feeding system.
2.Automatic Tension controller: you can input diameter and thickness parameter of base material based on replaced material, along with the rotated-loops changing, tension is decreased proportionally to achieve automatic tension control.
3.The machine adopts PLC One-touch centralized controls，advanced touch screen control system.It controls the speed of the extruder and compounding body at the same time, the extruder along with the compounding body to higher speed, lower speed, and proportional increasing or decreasing, assure film thickness is constant. According to requirements , set coating film thickness, the extruder can cooperate compounding body speed automatically, to reach setted the film thickness.
4. high efficient corona device, hydraulic for the network, are the first domestic, can effectively enhance the product peel strength.
5. Three roller compounding mechanism, back pressing roller makes compounding roller to force evenly and compounding firmly.
6. Peeling off silicone roller: compounding products peels off from cooling roller easily.
7. Compounding and filling regulating roller can overcome defects such as uneven of film thickness.
8. Disc slitting knife edge-cutter: sharp knife edge
9. High pressure blower sucks scrap edge quickly.
10. Car type extrusion machine
11.T- type die head
12.Automatic hydraulic changes filter ( Our Factory patent)
13.Surface rewinding (Double work-station ,Non-stopping)
