Double heads uncoiler machine metal sheet decoiler electrical machinery with motor power and speed control box

Motorised Double Head Uncoiler

The double head decoiler machine is an ideal solution for production plants where speed and continuity are critical, particularly in serial manufacturing. It is commonly configured with an steel straightener, punch press machine, NC feeder machine, making it ideal for motor rotor and stator lamination stamping.

Features

1. Equipped with two expansion reels spaced at 180°, connected by a rotating shaft for alternate uncoiling. While one reel is in operation, the other can be loaded by crane or forklift without shutdown, ensuring continuous material feeding.

2. Available in non-powered and powered versions. The non-powered type is driven by the tension of subsequent equipment with a brake handwheel, requiring no large storage space. The powered type is driven by a main motor and reducer via a sprocket.

3. Fitted with a positioning device. The rotating shaft is locked by a pneumatic positioning pin into the positioning hole to ensure stable material supply for downstream equipment.

4. Long-wheelbase support, compact structure, large load capacity, convenient loading and flexible operation.

Body structure

1. This machine is composed of three parts: frame, spindle case body and load rack. The main shaft box is the carrier with long wheelbase support. With small volume, small area occupation, large loading capacity and using flexible features.

2. It has motorized and motorless two types to option, it can work with straightener. 

Main shaft and tile

1. All nuts which needed to fix each part adopt non-slip nuts, to prevent them falling off during operation, and avoiding damaging the machine or injuring people.

2. Spindle screw and screw sleeve are made of fine machining to ensure the smoothness of adjusting inner and outer diameter and avoid unnecessary downtime.

Power part

1. Can be equipped with a motor and electronic control for powered uncoiling functionality.

2. Adopt vertical motor, low vibration, low noise, stator rotor part adopt pure copper coil, life is 10 times of ordinary coil, both ends are equipped with ball bearing, low friction, low temperature.

Electric control box

1. Adopt silver alloy relay, full copper coil, flame retardant safety base, long lasting and durable.

2. Adopt self-duplex flat button, the force is light, the key range is moderate, the building block type combination structure. The contact is made up of keto-base composite points with strong conductivity and large current, with a life span of up to 1 million times.

The base part

The overall structure is simple, it is convenient for general technical workers to assemble and replace, can greatly reduces the maintenance cost.

FAQs

What is the main advantage of a dual-station decoiler?

A dual-station decoiler allows one col to be loaded while another is feeding, enabling continuous production without stopping the press.

Can this dual-head decoiler be motorized?

Yes, we offer both manual and hydraulic options, depending on the production line speed and material requirements.

Is hydraulic expansion available?

Yes, the LIHAO series supports both Manual and Hydraulic expansion options.

Can it be customized for my stamping line?

Absolutely. Coil width, load capacity, expansion method, and control options can all be customized.
