Automatic Decoiler for Corrugated Fin Production Line

Product Introduction

The Automatic Decoiler for Corrugated Fin Production Line is the first material-feeding unit in transformer corrugated fin manufacturing.

It is designed to support, expand, unwind, and continuously feed steel coils into the corrugated fin forming machine.

With a 7 t coil capacity, 1600 mm maximum coil width, hydraulic mandrel expansion, and electric travel system, the decoiler provides stable material feeding for the following forming process.

The machine is linked with the production line control system so that the uncoiling speed automatically matches the forming operation, supporting smooth and continuous production.

Position in the Corrugated Fin Production Line

The Corrugated Fin Decoiler is installed at the beginning of the production line, directly before the corrugated fin forming machine.

Typical process:

Steel Coil → Automatic Decoiling → Corrugated Fin Forming → Automatic Welding → Reinforcement Spot Welding → Conveyor Transfer

Its main role is to provide a stable and continuous steel strip supply for the forming machine, reducing manual handling and supporting consistent downstream production.

Key Features

• 7 t Heavy-Duty Coil Capacity

The decoiler supports steel coils up to 7 tonnes, allowing wider and heavier coils to be used and reducing coil replacement frequency.

• Hydraulic Mandrel Expansion

The mandrel supports an expansion range of Ø470–520 mm and uses hydraulic expansion to securely grip the coil while allowing smooth unwinding.

• 1600 mm Wide-Coil Capability

The machine accommodates steel coils up to 1600 mm wide, matching the wide processing range of the corrugated fin forming line.

• Electric Travel System

The decoiler uses an electric motor with gearbox for stable movement and accurate positioning during coil loading and operation.

• PLC-Linked Line Operation

The decoiler works together with the forming machine control system, allowing uncoiling speed to automatically follow the production rhythm.

Technical Specifications

FAQ

1. What is the maximum coil capacity?

The machine supports coils up to 7 t with a maximum width of 1600 mm.

2. What coil diameter can the decoiler handle?

The maximum coil outside diameter is Ø1000 mm, with an inside diameter range of Ø470–520 mm.

3. How is the coil secured on the decoiler?

The machine uses a hydraulic expansion mandrel to securely grip the inner diameter of the steel coil.

4. How is the decoiler moved into position?

It uses an electric motor with gearbox for stable travel and positioning.

5. Does the decoiler work automatically with the forming machine?

Yes. It is linked with the production line control system so the feeding speed can match the forming process.

6. Where is the decoiler installed in the production line?

It is the first machine in the corrugated fin production line, installed before the corrugated fin forming machine.
