0.9MPa 4mm Alloy Steel Bopp Film Laminating Machine

4mm alloy steel 380V Bopp film extrusion laminating machine

Specification:

Main constructions:

1) Double Shaft-less paper roll stands suitable for 3-6 inch paper core,automatic lift ,easier operation .

2) Auto splicer device realize paper in 150-300 m/min speed exchange without decrease machine line speed

3) Ultrasonic type EPC system,makes frequent replacement materials operation more simple

4) Hydraulic lamination structure design , can make coating thinner and firm .

5) Trimming device make the finished coated paper rolls even

6)Special cutting knife and rewinder design makes high speed rewinding shafts exchange possible.

The pre-treat unit

• The pre-treatment includes corona treatment and static elimination on the surface of base materials. Especially in extrusion coating process, corona treatment is needed to assist molten web to permeate into the pores or cottony gaps on the surface of base materials under the pressure of pressure roll, improving the adhension between coating film and base materials.
• Corona treatment will stop when production line speed below 20m/min and automatically starts when speed above 20m/min.
• The corona machine is equipped with work condition indicating lamp, oil-immersed high-frequency transformer, electric digital meter reading output power and adjustable low-speed interlock. It will be warning on overheat,hyper-charger, breakdown and corona lost, and works with high-efficiency and low-consumption.

Extruder

• Extrusion machine is the key of extrusion laminating equipment and consists of screw,barrel and transmission mechanism. It has the functions of delivering, fusing, measuring, mulling of solid materials and delivering melt.
• Laiyi's self-developed screw is high-speed,high-cutting and high-mixing, and has many advantages like large extrusion output, low heat, small changes in extrusion pressure, no extrusion of non melt resins, no bubbles and energy saving.
• The extruder can equip newly designed auto-lifting function that can adjust air gap height at any time to adjusting the most suitable air gap height according to line speed.

​Bead cutter equipment

• Shrink-width makes two sides thicker, as a result, the two sides of the composite material need to be trimmed, otherwise the composite material will have some quality problems such as drape, crimp and unevenness.
• It is convenient to renew cutter and adjust effective width. It can save time and labor at the same time, and makes the products flat and smooth.

Compound machine

• The coumpound device consist of cooling roller, silicone rubber pressure roller, back-up roller, discharge roller, trimming deflashing device, wheelwork pneumatic device and some other devices. It is used to combine melted sheet film with basic materials and is the key device of extrusion lamination or extrusion coating. Its main functions are composite, cooling and shaping.
• Its production line is equipped with external hard chromium plating and steel rollers with double-deck clamp cover auger-type screw channel. the clamp cover of screw channel is filled witth cooling water to take away the heat of melted thin film so that composite thin film can get a great result in cooling shaping, and this greatly improves the fastness, smoothness and external beauty of composite.
