Automatic Continuous Working Type EPS Pre-Expander Polystyrene Foam Maker for Styrofoam products Manufacturing

Automated Metrology & Material Handling

Digital Gravimetric Feeding: Features an integrated electronic weighing system. Operators can define precise load weights via the HMI touchscreen; the system then executes automated, high-accuracy feeding to eliminate manual variance.

Intelligent Level Monitoring: Employs Korean-engineered vibration sensors to monitor material levels with high sensitivity, ensuring uniform particle density throughout the expansion cycle.

Fluidized Bed Efficiency & Maintenance

Optimized Aging & Transfer: The material level height within the fluidizer bed is fully adjustable to optimize the aging effect of expanded particles. A high-efficiency flap-feeding device ensures rapid, uninterrupted particle throughput.

Simplified Maintenance: An integrated crushing device at the base of the fluidized bed prevents material clumping and facilitates rapid, convenient cleaning during grade changes.

Core Component & Performance Matrix

System	Key Component / Brand	Operational Advantage
Pressure Regulation	Batton (Germany) / Yoshitake (Japan)	Constant-pressure stability; ±0.01MPa variance
Thermal Logic	Dual Proportional Valves	Precise high-density expansion control
Motion Control	Frequency-Inverter Spindle	Adaptive agitation for various material types
Level Sensing	Korean Vibration Sensors	Uniform bead density and volume control

Performance & Efficiency Optimization

High- Efficiency Flow Design: Large butterfly valve ensures stable vacuum and rapid discharging; DN 150 feeding valve reduces feeding time by 6- 8 seconds; vacuum cooling system with buffer tank improves pre- vacuum efficiency, significantly shortening the overall cycle.

Synchronous Operation: Dual- barrel vacuum feeding system enables simultaneous discharging and feeding, ensuring uninterrupted production.

Material Handling & Conveying System

Uniform Conveying: Four discharge ports for synchronous discharging; multi- port air supply in vacuum system ensures uniform ventilation of particles; wind- shielded feeding device (stainless steel) adapts to heavy materials, offering fast and durable performance.

Insulation & Stirring: Thickened insulation cotton reduces barrel heat loss; stirring spindle with frequency converter supports multi- speed adjustment, ensuring stable processes.

Precision Control & Stability Assurance

Sealing & Regulation: Four sets of discharge cylinders with imported sealing compo nents for long- term reliability; German Burkert proportional valves, pressure sensors, and temperature transmitters precisely control steam and cold air circuits, achieving constant tem perature and pressure foaming, suitable for multi- weight processes.

Air Supply & Temperature Control: Japanese SMC pressure reducing filter and sec ondary pressure stabilization system ensure stable compressed air; feeding fan with steam proportional valve maintains constant air temperature in various environments.

Production Efficiency

Protection System: Pipeline safety valves provide dual protection for steam pressure; stainless steel crushing and screening device intercepts agglomerates to prevent blockages.

Intelligent Functions: Automatic density weighing system displays real- time cycle weight and supports data interfaces; dual- vibration level gauge combined with viewport clean ing system avoids level misjudgment.

Durability & Maintenance: Key components use corrosion- resistant stainless steel; vacuum tank has inspection port, cooling system with imported hoses to reduce vibration and protect pumps.
