Components of Simple Steel Slitting Line

The line includes in decoiler, guiding device, slitting device, extension device, re-coiler, PLC controlling system. 

Coil Feeding Equipment
The complete line is consists of one manually decoiler with a capacity of 10000Kgs. The steel sheet is feeding to the leveling equipment under the function of friction and traction. The decoiler's running speed can be matched with cutting machine speed which controls the switch and has a press arm to press the coil to avoid the coil loose during rotation. Also, the hydraulic station is separate; it is off without expanding, which can save the power. It is only for this decoiler, so it can be used separately.

Guiding Equipment
Adopting guiding bar and sliding block to control the width and position of the steel sheet. The coil is guided in the correct position and passed to the roll forming equipment.

Slitting device
The machine has three rubber pinching rollers to drive the sheet. Transfer the main motor power to the rollers through chains and sprockets, and also transfer the coil sheet. This device slits the sheet, adjust the slitting blade and can slit different sizes. And guide device is also included, so it is convenient to adjust the slitting size manually.

Extension device
Which is in front of re-coiler and mounted with re-coiler together, it extension the sheet so can wind a tight coil; also it has a partition to divide the sheet separately.

Include stand, reducer device, re-coiler shaft, re-coiler expander device, mechanical support arm.

PLC Control Panel
The electric controlling system of this machine consists of five parts: operating system, touch screen, PLC control system, transducer and electricity part.
The controlling system of this machine uses modularized structure and has convenient, reasonable, canonical wiring arrangement, and its maintenance is quite easy. The independent operating console facilitates the mutual dialogue between the operator and the machine. The operation is easy and steady and can be chosen operation by manual or automatic.
