Coil Processing Equipment
1. Main Types
Uncoiler
Function: Unrolls coiled metal sheets (e.g., steel coils, aluminum coils) for subsequent production lines.
Types:
Double-head Uncoiler: Enables alternating operation for higher efficiency.
Hydraulic Uncoiler: Uses a hydraulic system to expand/contract the mandrel, adapting to coils of different inner diameters.
Cantilever Uncoiler: Simple structure, suitable for lightweight materials.
Uncoiler + Leveler (Decoiler + Leveler)
Combines uncoiling and leveling functions to eliminate internal stress in coils and ensure flatness.
Slitting Line
Cuts uncoiled sheets longitudinally into narrow strips for producing slit coils.
2. Core Components
Mandrel: The central component supporting and fixing the coil, expandable mechanically or hydraulically.
Hold-down Arm: Prevents the coil from loosening.
Leveler: Multi-roller structure to flatten wavy deformations in sheets.
Guide Device: Ensures proper alignment into downstream equipment.
Electrical Control System: Automated operation via PLC or CNC controls.
3. Application Scenarios
Automotive Manufacturing: Uncoiling and leveling of car body steel sheets.
Home Appliance Industry: Processing sheets for refrigerator/washing machine casings.
Construction Industry: Processing color-coated or galvanized steel sheets.
Hardware Products: Raw material preparation for metal containers or pipes.
Product Overview The uncoiler is a critical equipment in metal sheet processing lines, designed to unroll coiled materials (such as steel, aluminum, and copper coils) and deliver them smoothly to subsequent leveling, stamping, cutting, or forming processes. Widely used in automotive, home appliance, construction, and hardware industries.
Key Features: ✔ High-efficiency uncoiling with stable material feeding ✔ Adaptable to various coil diameters and strip widths ✔ Automated control for user-friendly operation ✔ Robust structure with extended service life
