30 Ton Hydraulic Automatic Double Head Decoiler

Hydraulic Automatic Decoiler

The 30 ton hydraulic automatic double head decoiler is a heavy-duty, high-automation coil handling equipment specially designed for large-scale metal coil processing production lines. As an upgraded and optimized version of the traditional single-head decoiler, it integrates dual-station loading structure, full hydraulic drive system and intelligent automatic control technology. It is mainly used for unwinding various metal coils such as steel coils, stainless steel coils, aluminum coils and galvanized coils. With a rated load of 30 tons, it perfectly matches the heavy-load, continuous and high-efficiency production demands of roll forming, stamping, cutting-to-length and other metal processing industries, effectively solving the problems of long material changing downtime and low production efficiency of traditional uncoiling equipment.

Core Structural Design

This double head decoiler adopts a heavy-duty integral welded steel frame structure, which undergoes high-temperature stress relief and shot blasting treatment after welding. The overall structure is firm, stable and resistant to deformation, ensuring stable operation under long-term 30-ton heavy-load working conditions. The core dual mandrel swivel base design is the key to its efficient continuous operation. Two sets of independent hydraulic expansion mandrels are symmetrically installed on the rotatable base, realizing dual-station alternate working mode.

Equipped with a professional hydraulic loading car and automatic diameter-adjusting material supporting device, the machine completes coil loading, positioning, clamping and fixing through hydraulic power. Compared with manual loading equipment, it greatly reduces manual operation intensity and improves loading accuracy and speed. The turbine worm deceleration driving mechanism is matched with long-distance bearing support points, which effectively enhances the equipment’s load-bearing capacity and operation stability, avoiding jitter and material deviation during high-load unwinding.

Fully Hydraulic Automatic Control System

The whole machine adopts a full hydraulic automatic drive and control scheme, covering hydraulic coil expansion, hydraulic coil loading, hydraulic tension adjustment and automatic speed matching. The hydraulic mandrel can realize stepless diameter adjustment to adapt to metal coils of different inner diameters, ensuring firm clamping without loose coil or material deviation during unwinding. The built-in high-precision hydraulic pressure stabilizing system maintains constant tension output during the entire unwinding process, avoiding material stretching, wrinkling and deformation, and effectively guarantees the processing precision of subsequent production processes.

Supported by an intelligent PLC control system, the equipment realizes fully automated operation including automatic coil loading, automatic unwinding, automatic parking and automatic station switching. It is equipped with laser distance detection and induction positioning devices, which can real-timely monitor the remaining material of the coil. When one coil is about to be exhausted, the system automatically prompts and completes station switching in a short time, realizing seamless docking of material supply. The running speed can be steplessly adjusted and automatically synchronized with the speed of the downstream production line, realizing integrated linkage operation.

Unique Performance Advantages

Zero Downtime Continuous Production

The biggest advantage of the double-head structure is the alternate working of dual stations. When one mandrel is driving the coil for unwinding production, the other mandrel can complete pre-loading, clamping and standby work. After the first coil is used up, the standby station can be quickly switched to work, completely eliminating the long downtime caused by single-head equipment’s repeated coil loading and replacement, and greatly improving the overall continuity and output of the production line.

Super Heavy-Load Stability

With a rated bearing capacity of 30 tons, the equipment is optimized for heavy-load structural design. The thickened steel frame, reinforced bearing components and stable hydraulic drive system enable it to stably handle large-specification and heavy-weight metal coils. It effectively avoids equipment vibration, displacement and component wear under heavy-load operation, with lower failure rate and longer service life compared with ordinary light-duty decoilers.

High Precision and Low Material Loss

The constant-tension hydraulic control system and intelligent speed matching technology ensure uniform and stable unwinding speed, no sudden speed change or material loosening. It perfectly adapts to thin-plate precision processing and thick-plate heavy-duty processing scenarios, reducing material stretching, wrinkling, scratching and waste caused by unstable unwinding. The precise positioning function also ensures accurate material feeding, laying a foundation for high-precision subsequent processing.

Labor-Saving and Cost-Effective

The full hydraulic automatic operation mode reduces manual participation links. A single operator can complete equipment operation, coil loading and parameter adjustment, greatly reducing labor costs. At the same time, the continuous production capacity significantly improves production efficiency, increases hourly output, and reduces comprehensive production and time costs, bringing higher economic benefits for industrial production.

Daily Operation and Maintenance Tips

During daily operation, it is necessary to regularly check the hydraulic system oil pressure, oil quantity and pipeline tightness to avoid oil leakage and insufficient power output. Regularly clean the mandrel and bearing parts to prevent metal debris from affecting the clamping accuracy and operation stability. Lubricate the transmission components on schedule to reduce mechanical wear. In addition, regularly calibrate the induction positioning and speed synchronization system to ensure the accuracy of automatic operation.
