PLC Control System Metal Slitting Line High Precision Steel Slitting Machine
Metal Slitting Line Working procedure:
In the beginning, the coil is loaded on the coil car by crane and brought to the uncoiler by operating the coil car. Coil car centralizes the coil with the uncoiler mandrel and the coil is mounted on the uncoiler. Mandrel is expanded. Snubber roll rotates the coil. Peeler breaks the straps and brings the pre end upto Pinch roll. The Pinch roll drives the coil end upto the slitter. Then its drive is disconnected. Slitter moves the slitted strips further. Slitted strips are threaded through loop table and drag tensioner into the recoiler drum. Recoiler winds one turn on loose coil.

Descriptions:
Components of the 1250mm semiautomatic slitting line: coil car, hydraulic decoiler, slitter, hydraulic tension station, hydraulic recoiler
Composed device:
1. Decoiler
The motor will drive it running and help the decoiler to feed the material to the next device
It can expand and shrink to meet the different coil Inner diameter's requirement.
It is one of the important part of the slitting line
Capacity: 5T
2. Slitter
At the entry part, it is equipped with the side guide device to prevent the sheets not directly go into the slitter
Steel slitting line' s slitter part designed with the bracket movable structure to make it easy to adjust the slit width
It should be equipped with the blades, shim , bakelite plates or the rubber band to make the slitting possible
3. Scrap winder
In the slitting line it is designed to receive the waste materials on both sides
And a shaft with the 5.5 KW motor to wind the material with speed adjustment
4. Tension stand
Two shafts will be equipped with spacers to divid the strips one by one
The press device with felted woolen will create the first tension part to ensure the tight and even recoiling quality
The press part is adjustable as per the various thickness requirements
5. Recoiler
The press arm will divide the strips one by one and create the tension with the tension stand
The motor makes the speed adjustable
Recoiler is the most importmant part of the whole steel slitting line.
