PP/PE hollow shutter making machine realizes continuous production of PC/PE/PP hollow grid plate, which isapplicable to construction decoration, advertisement collocation, and noiseinsulation of highway as well as packaging. PE/PP hollow grid plate is an indealsubstitute for paper box in making packaging box. It is characterized by lightweight, high intensity, dampproof, and anticorrosion. The width of the productsis 1220mm-2100mm, and the thickness is 2mm-12mm.
Extruder:
The specially designed screw and the advanced controlling system ensureexcellent plasticization, high output and stable extruding.
Screen changer:
Quick screen changer of hydraulic system ensures the short course of screenchanging. Double-position combined with special sealing structure guaranteestable operation of screen changer.
Mould:
Mould adopts high-quality alloy steel and throttling device to ensure evenpressure of feed influent at the mould lips, and also differential action ofup-down piece guarantee even thickness of the plate.
Vacuum calibrating stable:
Heating exchanging and cooling system of quick speed in calibrating systemalternate effectively and ordinally with vacuum system, which ensurescalibrating precision. Vacuum system composes two independent subsystems andeach is equipped with several fixed circulating vacuum lines of three-pointtype. Meanwhile, each line carries vacuum regulating system and vacuum displaysystem that realize even and stable vacuum degree of plate surface.
Tractor:
There are two tractors. The first one is of high powr, high reduction ratio,multi-roller type, well low-speed operation, high traction and is able to drawthe plate up from the calibrating table evenly and synchronal. The second one isdesigned to remove stress, and in addition it is equipped with edge-cuttingdevice to ensure the valid width and smooth cut of the edges.
Stress remover:
The advanced large area conductive heating mode can effectively remove thestress of plate and further improve planeness of the plate.
Cutting machine:
Accurate instant length-fixed cutting and automatic up-down dischargingsystem combined with alloy steel sharp blade realize high quality of cutting
