pp hollow corrugated sheet machine/plastic hollow grid board extrusion line/pp hollow grid sheet machine

      pp hollow corrugated sheet machine 

High efficiency single screw extruder. It can produce pc hollow  board/sheet. The thickness is from 2mm to 12mm, width is from 1200mm to 2100mm. This sheet/board is mostly used as construction,adornment industries and so on.

 Main Composition  

Photos of Main Composition

1.Automatic dry feeding system

2.SJ120/30 single screw extruder

The specially designed screw and the advanced controlling system ensure excellent plasticization, high output and stable extruding  

3.T-die mold

Mould adopts high-quality alloy steel and throttling device to ensure even pressure of feed influent at the mould lips, and also differential action of up-down piece guarantee even thickness of the plate

4.Vacuum Calibration Unit

Heating exchanging and cooling system of quick speed in calibrating system alternate effectively and ordinally 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 surface

5.Haul-off Device

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 draw the plate up from the calibrating table evenly and synchronal.

6.Oven

The advanced large area conductive heating mode can effectively remove the stress of plate and further improve planeness of the plate.

7.The Second Haul-off Device and Cutting Device

The second Haul-Off  is designed to remove stress, and in addition it is equipped with edge-cutting device to ensure the valid width and smooth cut of the edges.

Accurate instant length-fixed cutting and automatic up-down discharging system combined with alloy steel sharp blade realize high quality of cutting
