Product Specification

Automatic blue plastic Extrusion Blowing Moulding 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 necessary air pressure is 0.4~0.6 Mpa, air consumption is 0.6~0.8 M3/min. 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. The necessary water pressure is 0.2~0.4 Mpa, water consumption is 2500L/hour.

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.

1. Toggle mould locking mechanism guarantees big clamping force, no expansion of mould, no increase of high pressure air consumption.

2. Sliding transferring guarantees stable, fast and accurate operation.

3. Self-locked high pressure sealing makes stable sealing, no impact, and no wearing. Indepentant controlled stretch bar provides accurate stretching.

4. Automatic preform handling equipment and robots for perform loading & take-out make production process fully automatic.

5. Latest high speed PLC and Chinese-English HMI are adopted. The time setting can be accurate in 0.01 second. It makes the operation more easy and the technical setting more accurate.

6. High quality pneumatic parts are imported from Europe or Japan. Fast feedback solenoid valve (from Germany) is adopted in high-pressure blowing. It ensures the second blow time accurate and controllable.

7. Centralized heating makes even, stable effect, and reduces power consumption mostly.

8. Close-loop heating control system with corresponsive high accurate digital meter, and imported adjustable high power frequency controller, make sure stable heating, energy saving and not to be affected by fluctuated voltage. IR lamp which is most efficient for PET heating, is fully considered for lower power consumption and higher production efficiency.
