Automatic 10L 15Liter 20 litre Plastic Drum HDPE Blow Molding
Machine
Introduction
Extrusion System
The extrusion system includes gear box, extrusioin motor, inverter,
screw, barrel, head and die. The extruder adopts gradient mixing
type with high-speed energy saving design. Material of screw: High
quality nitriding steel 38CrMoAlA,with nitriding surface
HV≥800,brittleness≤2. Material of barrel: High quality nitriding
steel 38CrMoAlA,with nitriding surface HV≥900,brittleness≤2. The
head runner has good design and head matel is processed for higher
hardness. The die and core will be made according to your product
design and size.
Clamping Unit
Clamping unit is composed of front & back platens, clamping seat,
carriage seat, mould stroking & clamping hydraulic cylinders,
synchronizing mechanism, with the structure of nether crank design.
Platen movements open & close, carriage up & down is assisted with
linear guide rails & ball bearing sliders to increase action
smoothness and position precision. The end positions & slow speed
positions are controlled by proximity switches or transducers. Our
nether bent arm central clamping structure insures the clamping
force bearing to mould in balance, easy for scraps auto-deflashing,
also good for mould's lifespan.
Electric Control
The electrical control system is composed of operation panel,
temperature control module, PLC, input & output module, proportion
board, contactors, voltage stabilized source, air swtiches, mid
relays, proximity switches, inverter and motors. The operation
panel contains power switch, touch screen, alarm, hot cutter knob,
auto cycle button, emergency stop button, action reversion button,
extruding speed button.
Hydraulic System
The hydraulic system is mainly composed of motor, pump, pressure
regulating valve block, reversing valve blocks, cylinders and oil
chillers. It controls platens open & close, carriage up & down,
extrusion system up & down, blow pin actions, or even spinning cut
and so on. Our hydraulic system has been updated with proportion
valve and mechanical shuttle valve for action stability and
precision. It insures the oil pressure output fast but smooth,
action performance is quick but with less impact.
Water & Air Supply
The pneumatic system contains air cylinder, air valves, air
filters, air tubes, fast plugs and so on, for controlling the
actions of head inner blowing, blow pin blowing, auto-deflashing,
or pushing in & out for some special moulds. The water system
contains water distributing blocks, ball valves, tubes, connectors
and so on, for chilling the screw & barrel, hard gear box, blowing
units and moulds.
Automatic Production
our machine supports auto-deflashing control system and pneumatic
hardware, the scraps can be on-line removed automatically through
auto-deflashing mould. Scraps fall down and slide outside of
machine through a slide channel. The finished products are pushed
out from another side together with platen carriage down action
with the guidance of bottle collective shelves. The conveyer system
can be equipped to take scraps into crusher, and convey the
finished products to leakage tester or packing table. During the
producing period, the machine can work automatically without the
worker's help.
Working Flow Arrangement
The whole producing line totally need 2 workers. Worker No.1 takes
charge of material mixing and feeding, he collects the crushed
scraps into color mixer, operate the material mixing of new
material, crushed material and color master batch. After mixing he
carries material into material source tank, the auto-loader will
feed material automatically. The other worker takes charge of
bottle packing, and take the packaged bottles into storage area.
