Efficient Wire Coil Compacting and Strapping Solutions

Handling large volumes of wire coils presents challenges in logistics, storage, and transport. The SHJLPACK wire coil compacting and strapping machine offers a robust solution to these issues by streamlining the packaging process, ensuring coils are tightly bound and protected.

This equipment is designed for substantial production demands, providing a well-packed product that is better protected against potential damage, moisture, and dust. Both semi-automatic and full-automatic systems are available, with specific designs tailored by our engineering team to meet customer requirements.

From compaction to strapping, the SHJLPACK line provides a reliable packaging solution. It is compatible with various packaging materials, including PET or steel strap, and can be integrated with additional equipment like wrapping stations or stackers for a fully automated line.

Addressing Traditional Coil Handling Pain Points

Inefficient coil handling methods can lead to significant drawbacks:

• High Damage Rate: Coils can loosen or deform during transport without proper compaction, leading to potential damage.
• Excessive Labor: Manual handling of heavy coils is labor-intensive and poses ergonomic risks.
• Inconsistent Tension: Suboptimal strapping can result in coil slippage or damage to the wire.
• Storage Inefficiency: Loosely packed coils occupy more valuable warehouse space.

Our compacting and strapping machine directly addresses these issues, offering a more efficient and reliable process.

Core Machine Functions

The SHJLPACK wire coil compacting and strapping machine performs several critical functions:

• Seamless Conveyor Integration: Automatically receives coils from upstream processes via a conveyor, minimizing manual intervention.
• Intelligent Hydraulic Compacting: Uses a multi-stage hydraulic press to compress coils to a uniform, predefined density.
• PET/Steel Dual-Mode Strapping: Supports both PET and steel strapping bands, allowing flexibility based on transport requirements with precise tension adjustments.
• Automatic Unloading: Discharges the strapped coil onto a downstream conveyor or pickup station.

These functions significantly cut handling time and improve overall reliability.

Technical Architecture Highlights

The system's design incorporates advanced modules for optimal performance:

Module 1 – Conveyor Integration and Automated Pick-Up

• Precision Positioning: Utilizes sensors for accurate coil placement (typically ±0.5 mm tolerance).
• Enhanced Conveyor Material: Often employs robust, coated belts designed to handle heavy loads and sharp wire ends.

Module 2 – Multi-Stage Hydraulic Compacting

• Variable Pressure Range: Features an intelligent hydraulic press with adjustable pressure (e.g., 80–350 kN) based on coil characteristics.
• Servo Motor Efficiency: Servo-driven hydraulic pumps can offer significant energy savings (up to 23% compared to legacy systems) by only consuming power when needed.
• Overload Protection: Systems may include features for real-time pressure monitoring to prevent damage.

Module 3 – Smart Strapping Workstation

• PET vs. Steel Strap: Supports switching between PET straps (corrosion-resistant, light) and steel straps (superior tensile strength for heavy loads or high-impact transit). Dual-mode designs allow quick material changes.
• Dynamic Tension Control: A closed-loop system continuously measures and adjusts strapping tension (typically within a ±2% error margin) for a stable package.
• Rapid Coil Band Change: Includes features for quickly loading and threading new strapping coils of common sizes (e.g., 13 mm or 19 mm).

Key Advantages

Investing in a SHJLPACK compacting and strapping machine offers distinct benefits:

1. Compact Footprint: Can occupy significantly less floor space compared to older or manual systems.
2. Predictive Maintenance: Integrated sensors can provide data for monitoring wear and scheduling maintenance, reducing unplanned downtime.
3. Broad Material Compatibility: Capable of handling a range of wire diameters (e.g., Φ5 mm to Φ30 mm) by adjusting settings.
4. Energy Efficiency: Designed with energy-saving components like servo-hydraulic systems.
5. Custom Integration: Offers interfaces (like open API) for data integration with factory management systems (ERP, MES).
6. Enhanced Safety: Reduces the need for manual handling of heavy coils.
