APPLICATION
This
machine may be mainly used for
the shaping extrusions of rubber
compounds at room temperature.
When fitted with different extruder
heads, it can achieve many rubber
products in rubber industry, for
example, extruding of inner tubes
and tire treads, coating of tube
and conveyer belt, shaping extrusion
of profiles of profiles of rubber
sheet
and plate.
In addition, it also incorporates
into a multiple
extrusion unit together with other
(hot or cold feed) extruders.
This machine
has good plastifying and mixing
properties which can result in
uniformity goods, low extrusion
temperature, high extrusion capacity,
low power consume, wide processing
adaptability.
STRUCTURE FEATURE
This machine consists
of motor, reduction gearbox, feed
device, screw, barrel, extrusion
head, temperature control unit,
electric control device
and frame, and so on.
1. Main motor is a DC motor with
DC speed adjustor. Gear reducer
is
multi-step,
tooth surface hardened type, and
immersion lubrication/oil
pump are adopted.
2. Feed section is double-walled
design for water-cooling, and
feed roll is
designed for
water-cooling with and rotary
joint and adjustable scraper
knife for continuous
cleaning and is driven by splined
coupling ring.
3. Screw is made of nitrided steel
38CrMoAIA, surface hardened by
nitriding,
nitriding depth 0.5-0.7 mm, and
surface hardness 900HV.
extrusion barrel
is drilled for water-cooling and
heating with 7-12 pin
rows, each
having 6-10 pins and is made of
nitrided steel 38CrMoAIA
in the bore
surface hardened by nitriding,
nitriding depth 0.5-0.7 mm,
and surface
hardness approx. 950HV.
4. Temperature control unit (TCU)
for the cooling of screw, pin
barrel, feed
barrel, feed
roll and extrusion head.
5. Frame is welded by steel profiles.
