HDPE large diameter hollow wall winding
pipe (200mm-3000mm) produced by the production line has a unique "I"
shape structure, so it has the characteristics of high ring rigidity, high
impact strength, low meter weight, creep resistance, external pressure
resistance, corrosion resistance (acid, alkali, salt, etc.), pollution-free,
long service life (up to 50 years), etc. The pipe is widely used in municipal
drainage and sewage system, and it will be the renewal product of cement pipe,
cast iron pipe and ceramic pipe. Low assembly cost, easy operation, easy connection
and economy will make the pipe have more extensive application prospect and
market potential.
Production line features:
HDPE large-diameter hollow wall winding
pipe production line is designed with advanced technology, equipped with the
first single screw extruder (square pipe extrusion), square pipe extrusion die,
vacuum sizing water tank, spray cooling water tank, the second single screw
extruder (rubber extrusion), spiral molding machine, cutting machine and
stacking platform.
The first single screw extruder (square
tube extrusion) and the second single screw extruder (rubber extrusion): low
energy, low temperature plasticization (for material characteristics), high
efficiency extrusion principle. The unique design of variable pitch, solid-liquid
material separation screw, the unique design of feeding system ensure the
high-yield extrusion, and the special design of strong mixing section ensure
the uniform plasticization of raw materials at low temperature.
Spiral forming machine: it adopts advanced
multi axle box transmission structure, with the characteristics of large
transmission power, stable operation, long service life, etc. The unique
compound die, spiral rotational molding and the design of two extruders ensure
the efficient extrusion of high-quality winding pipes. The second rubber single
screw extruder can move up and down, left and right. The control of PLC and
touch screen system realizes the operation automation and easy operation.
Cutting machine: fixed length cutting, PLC,
touch screen system control truly realize the operation automation, easy to
operate.
Control system: PLC, touch screen system
control. Multi point control: square tube extrusion, PE rubber extrusion,
spiral winding molding and cutting processes are all controlled by the control
system synchronously. Two touch screens can independently control the extruder
and winding molding.
