PP corrugated hollow board extruder machine line for turnover boxes
1. Extruder: The specially designed screw and the advanced controlling system ensure excellent plasticization, high output and stable extruding.
2. Hydraulic filter: Quick screen changer of hydraulic system ensure the short course of screen changing. Double-position combined with special sealing structure guarantee stable operation of screen changer.
3. Mould: Mould adopts high-quality steel and throttling device to ensure even pressure of feed influent at the mould lips, and also different action of up-down piece guarantee even thickness of the plate.
4. Vacuum calibrating table: Heating exchanging and cooling system of quick speed in calibrating system alternate effectively and with vacuum system, which ensures calibrating precision. Vacuum system composes two independent subsystems and each is equipped with several fixed circulating vacuum lines of three point type. Meanwhile, each line carries vacuum regulating system and vacuum display system that realize even and stable vacuum degree of plate operation.
5. Tractor: There are two tractors. The first one is of high power, high reduction ratio, multi-roller type, well low-speed operation, high traction and is able to draw the plate up from the calibrating table evenly the valid and smooth cut of the edges.
