TheThree-layer Greenhouse Film Blowing Line of
Jingcheng Brand is mainly composed of
three extruders,a compounding
die head,acooling
air
ring,ahaulingunit,acoolingunit,atemperature
and electric control
system,andetc.It
is mainly used to produce three-layer compounding greenhouse
film.After changing
certain
components,it
can also produce
geomembrane.This has the
following characteristics:
1.The screw and
barrel of extruder are uniquely designed
bythe company
itself.And they are consigned to
be processed bysome domestic
professionalmanufacturers.Besides,
they areequipped withstrong bushing.All these
will increase plasticizationandoutput.
2.Thehard surface gear
box has properties of low noise,high
drive efficiency,stablerotation and
long service life.
3.It
adopts cylindrical type filter.The screen
changing period is **8 times of common screen changing type.It not
only makes up the defect of material leakage of fast screen
changing device,but also effectively prolongs screen changing
time.
4.The
die head adopts central material feeding type spiral runner
three(five)-layer coextrusion die head.The material is high quality
carbon steel.Through several chanels of heat treatment
technology,its deformation decreases greatly.
5.Hauling roller and coiling roller are
conducted dynamic balancing test,rectifying,and accurate grinding
prcessing.
6.It
adopts inserting plate folding mode,which can effedctively decrease
hauling frame's volume,reduce space and lower purchasing
costs.
