Features
Variable Frequency Drive Linkage
Employs an active motor drive system with a variable-frequency unwinding speed adjustable within the range of 0–20 m/min, enabling fully automatic speed synchronization with downstream forming machines or feeding devices.
01
Closed-Loop Constant Tension System
Integrates tension sensors with a hydraulic braking system to perform real-time micro-adjustments of unwinding resistance, ensuring constant tension operation throughout the entire process and completely eliminating material stretching, deformation, or accumulation.
02
Hydraulic Expansion Mandrel
This mandrel has a design that helps it center and position automatically. It works perfectly with steel coils that have a diameter of 480 to 600 mm. This makes it easy to load coils and ensures they don't slip.
03
Pneumatic AntiSplay Pressure Arm
The machine has a pneumatic arm that presses on the steel coil from the outside. This keeps the coil secure. Prevents the outer layers from coming loose or the edges from getting damaged during unwinding. This helps keep the operation safe.
04
Intelligent Central Control System
The system comes with a Siemens PLC and a touchscreen. You can. Recall important settings like tension and speed with just one touch. The system also has a self-check feature that finds faults and shows error codes, on the screen. This helps you fix problems quickly.
05
Main Structure
Base and Frame: Welded steel structure, designed to support the weight of the coil.
Expanding Mandrel: Hydraulically driven; expands internally to grip the steel coil.
Drive System: Variable-frequency motor coupled with a reducer, driving the mandrel to rotate and unwind the coil.
Tension Control Device: Hydraulic brake or generator-type damping system, integrated with sensors.
Press Arm: Pneumatically or hydraulically actuated; presses against the outer surface of the steel coil to prevent loosening.
Advantages
20% Higher Output
The unwinding unit prioritizes "rapid response," automatically adjusting its speed via variable frequency control to synchronize with downstream equipment. It feeds material exactly as fast as the downstream line runs-preventing material accumulation or speed drops-thereby boosting overall line efficiency by a full 20%.
30% Reduction in Scrap
Continuous constant-tension control ensures the material is never stretched thin and remains completely free of creases. This makes it ideal for processing sheet materials with stringent surface quality requirements. Savings on scrap reduction alone can amount to over 30%.
1 Person, 10 Minutes
Previously, changing rolls required several people wrestling with tools for half the day. Now, thanks to a combination of hydraulic expansion shafts and pneumatic pressure arms, a single operator can perform a roll change effortlessly-using only their bare hands-in just 10 minutes.
Worry-Free Durability
The machine frame has undergone tempering treatment to prevent deformation, while the hydraulic disc braking system ensures stable, precise stopping. With less than 20 hours of downtime due to malfunctions per year, the unit requires virtually no maintenance-offering you complete peace of mind.
Application Scenarios
Roll Forming Lines
Provides continuous material feed for C/Z purlin, roof panel, and wall panel forming machines.
01
Stamping Lines
Supplies metal strips to mechanical and hydraulic press machines for automotive parts production.
02
Slitting Lines
Unwinds large coils for cutting into narrower strips in metal processing plants.
03
Welding Lines
Feeds metal strips to tube welding machines and structural component production lines.
04
Leveling Lines
Supports coil unwinding for sheet metal leveling and cutting-to-length operations.
05
Packaging and Shipping
Regarding the Motorized Decoiler you have ordered, our standard factory packaging and delivery procedures are as follows:
Secure Packaging: Prior to shipment, we apply anti-rust oil to all exposed machined surfaces of the machine, followed by an outer layer of moisture-proof film. The main unit is securely packed in an export-standard fumigated solid wood crate (featuring a baseboard thickness of at least 18mm); the interior is firmly braced with soft cushioning materials to ensure the machine remains stable and does not shift during the rigors of sea transport. In the event of oversized components, these will be shipped as bare cargo-treated with anti-rust agents-and clearly marked with hoisting labels.
Included Accessories: Your control cabinet, spare parts, and the machine's inspection report will all be consolidated and packed within a single crate to facilitate convenient unpacking and inventory verification upon receipt.
Logistics Tracking:As soon as the machine is dispatched, we will forward the packing list and Bill of Lading to you, while simultaneously providing the estimated time of arrival (ETA) at the destination port to assist you in smoothly navigating local customs clearance and inspection procedures.
FAQ
Q1: What types of metal coils can this machine handle?
A: Our motorized decoiler can handle various metal coils including galvanized steel, cold-rolled steel, hot-rolled steel, aluminum, and stainless steel, with thickness ranges from 0.3mm to 3.0mm.
Q2: How does the tension control system work?
A: The system uses a hydraulic brake with adjustable pressure to maintain consistent coil tension. The PLC automatically adjusts tension based on material thickness and processing speed to ensure smooth unwinding.
Q3: Can the motorized decoiler be integrated with existing production lines?
A: Yes, our motorized decoiler can be easily integrated with various downstream processing equipment including roll forming machines, press machines, slitting lines, and leveling lines, with customizable control interfaces.
Q4: What is the expected service life of the machine?
A: With proper maintenance, our motorized decoilers have an average service life of 10-15 years. Key components come with a 12-month warranty and we provide lifelong technical support.
