Here's a professional English translation of the 7-ton hydraulic decoiler introduction, covering its functions, structural design, technical features, and industrial applications:
1. Equipment Overview
Definition: A hydraulic decoiler is an industrial machine driven by a hydraulic system, designed to uncoil metal rolls (e.g., steel plates, aluminum coils, copper strips) with a maximum load capacity of 7 tons, ideal for automated handling of medium-to-large coils.
Core Functions:
Precisely controls uncoiling speed and tension to prevent material deformation or scratches.
Integrated weighing module for real-time weight monitoring, aiding production management and inventory control.
Compatible with continuous production lines, synchronized with levelers, shearing machines, etc.
2. Structural Components
1. Hydraulic Power Unit:
- High-pressure hydraulic pump station powers arm lifting and mandrel rotation.
- Equipped with relief valves and pressure sensors for system stability and safety.
2. Load-Bearing System:
Heavy-Duty Frame: Welded steel structure with anti-deformation design, supports 7-ton dynamic loads.
Decoiler Arms: Hydraulic telescopic arms adapt to coil inner diameters (typically Ø450-Ø800mm).
3. Weighing Module:
High-precision load cells (±0.5% accuracy) integrated into the mandrel or base.
Data transmitted to PLC for weight display, overload alerts, and production analytics.
4. Control System:
Touchscreen HMI (Human-Machine Interface) with preset material parameters (thickness, width, tension).
Supports manual/auto modes; optional remote monitoring.
5. Safety Features:
Mechanical limiters, emergency stop buttons, hydraulic overload protection.
Optional laser edge detection to prevent misalignment.
3. Working Principle
1. Loading: Coils are placed onto the mandrel via crane/forklift; hydraulic clamps secure the inner diameter.
2. Uncoiling: Hydraulic motor rotates the mandrel to release the coil, with tension control for steady feeding.
3. Weight Monitoring: Load cells track coil weight in real time, syncing data to production management systems.
4. Synchronized Production: Uncoiled material feeds downstream equipment (e.g., levelers, stamping machines).
4. Technical Features
High Load Capacity: 7-ton design for metal coils (1.0-12mm thickness, 1000-2000mm width).
Precision Hydraulics
Proportional valves adjust speed (5-30 meters/minute) to match line
Hydraulic pressure: 16-25MPa, with fast response and low noise.
Smart Weighing Integration:
Weight data networked with MES/ERP systems for traceability.
Automatic shutdown on overload to prevent damage.
Modular Design:
Expandable with photoelectric alignment or coil-end detection modules.
Quick-change coil mechanism reduces downtime (≤3 minutes).
5. Applications
Metal Processing: Uncoiling steel/stainless steel for automotive parts, appliance panels.
Packaging: Feeding aluminum foil/tinplate for canning, printing lines.
New Energy: Precision uncoiling of lithium battery electrode foils (high tension stability required).
Special Environments:
High-temperature workshops (heat-resistant hydraulic oil + protective coatings).
Corrosive settings (stainless steel critical components).
