Sell Five/Seven Layer Co-Extrusion Barrier Sheet Line

This production line is mainly used to produce high barrier sheet. The form of merginglayers is PP/ ADH/ EVOH/ ADH /PP or PP/ ADH/ PA/ ADH /PP This sheet is mainlyused in wrapper of food, medicine and cosmetic. To take this sheet as wrapperis not only to separate effectively oxygen and air, but also to separate the odourgiven off by the wrapper thus the wrapper can achieve a long-term quality andfresh assured. The production Line provides three/five extruders all of whichare feeding material automatically. PP extruder provides static mixer which canmake the materials plasticized and mixed fully. The screws of EVOH, PA and ADHextruders are specialty. These three extruders all provide melt gear pump so thatthey can feed materials precisely and stably pump so that they can feed materialsprecisely and stably, the duplex hydraulic change net device can realize high-speednon-shutdown changing net on the course of production. After the three materialssimultaneously enter the layer merger they are combined to five/seven layersand enter into the nose and are extruded evenly, every set of extruders hasprotected device of excess pressure and overflow in order to ensure the servicesafety. The size of the opening of the nose can be adjusted arbitrarily in thescope of the products end the width of the discharged material also can be adjustedThe discharged material will be shaped on the three rollers the gap adjustmentof the three rollers machine can be displayed by meter. The three rollers machinemay he adjusted at the same time or separately. The hydraulic station in additionsets up super oil temperature alert device. The whole production line mountschain safety device, once the emergency situation takes place, to pull theSafety rope or press the emergency push-button, the whole production line shut-downroller will be opened automatically. Installed on the track the three rollermachine, cooler frame, and traction motor can be moved fore and after, when theyare moved, only need to press the button.
