PP/PE Woven Bag Making Machine
is developed continuously by ourselves, based on our productionexperience of more than twenty years. It is characterized byadvanced technique, reliable quality, easy to operate, and highautomation, which is used widely in the industries of chemical,petrochemical, cement, metallurgy and mining, for packaging,storage and transportation of many kinds of materials.
The line uses PP or PE as raw material, through the flow-castingcoating and lamination technology, achieving single-sided /double-sided coating or paper-plastic lamination with substrates(plastic woven fabric), to produce coated or laminated products.The line is equipped with advanced electrical and mechanicaldevices throughout the whole production flow from substrateunwinding, lamination to winding, to achieve single control andgroup control. The dual-station unwinder uses EPC for automaticguiding control of substrates, and brakes for surface tensioncontrol of substrates, achieving pneumatic splicing and non-stoproll changing. The laminator is equipped with preheating roll forpreheating and drying of substrates. Laminating roll, siliconrubber roll and press roll are of dual-interlayer forced watercooling structure, with good cooling effect. The dual-stationwinder adopts constant-tension surface friction winding, pneumatictransverse cutting, roll changing without shutdown, and equippedwith adjustable edge-trimming device, edge-strip blowing device,and length counting device.
Features:
1. The extruder adopts two-layer construction, with long usefullife and good stability. The computer-simulation designed runner ischaracterized by large extrusion capacity, good plasticizationeffect, and low energy consumption. The die is convenient foradjustment, and uniform film flowing. The width at both sides ofthe die is manually adjusted.
2. The laminator adopts a new three-roll construction, which ischaracterized by uniform pressing, easy to operate, safety andreliability.
3. The winder adopts swing-roll automatic tension control andpress-arm horizontally pushing, to achieve straight winding andsmooth surface. (An automatic roll unloading device isoptional.)
4. Equipped with a turn bar system, to accomplish double-sidedcoating for tubular fabrics in one process.
5. about coating and lamination with substrates for jumbo sacks,a leveling and braking device shall be equipped, to guarantee thefabric surface shall be level before coating.
6. The line can be equipped with HMI and PLC, to achieveautomation functions such as program linkage adjustment, failureinterlock, etc.
7. The lamination speed can be up to 200m/min, as per thecustomers'' requirements.
