3 in 1 decoiler straightener feeder is especially suitable for high strength steel, enhancing the processing precision. Machine has adopted electric straightening precision adjustment which is easier to adjust than by manual. Electric and electronic parts are adopted European standard products, better in safety, stability, and lifetime.

Main Components of 3 in 1 Decoiler Straightener and Feeder

1.Uncoiler
Function instruction: uncoiling is to fix coil on the spindle of uncoiler, a supporting table to support coil Inner diameter, while working automatically, through material loop controlling instruction to make spindle uncoiling and loosing coil intermittently, equipped with coil diameter detection, to control uncoiling speed, ensure uncoiling line speed is uniform velocity, improved material loosing problem.
Components included: expansion and contraction part, press arm part, limit wheel part, material loop controlling part.
Expansion method: hydraulic expansion.
Spindle expansion range: Φ450-Φ530mm.
Spindle driven motor: AC motor, with an inverter.
Spindle driven method: variable frequency gear motor.
Spindle brake: disc brake.
Spindle uncoiling direction: down uncoiling.
Press material wheel specification: PU rubber tires
Press material wheel driven method: AC motor, with inverter
Function of press arm: from cut off bundling belt which is used for fixing coil until the coil head is pressed tightly by straightener roller, to prevent coil rebounding; while whole feeding line working, let the coil uncoiling smoothly, to prevent coil dispersing and the press arm is motorized, with tracking and follow up function ie. Rotating speed of press arm roller is absolutely the same with uncoiling line speed, then tensioning metal strip, to prevent coil loosing.
Press material wheel adjusting method: through change angle of press arm to change encoder feedback single to adjust speed.
Press arm moving method: driven by air cylinder, can be opened or closed manually.
Limit wheel: located on the upper left & right of uncoiler（double limit wheel）, unpowered, can be rotated along with any external force, for preventing coil of sideslip while uncoiling.
Limit wheel adjusting: two limit wheel can be discretionary adjusted, driven by hand wheel and gear, broadside of slide seat has a dividing rule for reference
Limit wheel motion: outer limit wheel is doing open/close motion driven by air cylinder, internal limit wheel without open/close motion, just move along direction of coil width, outer limit wheel just can be operated by touch screen in manual version, while automatically working, it needs to be closed, then can meet safety requirement of before working.
Surface process of the limit wheel: high frequency with parkerizing for rust protection.
Material loop control: through inducting material loop to feedback signal by the infrared photoelectricity induction switch under press arm, to control uncoiler spindle of start/stop, to ensure enough buffer material loop between uncoiler and straightener.
2.Loading Car Part
Function instruction: be used for moving coil to spindle of uncoiler smoothly, while uncoiling and entry the material head into straightener, it is used for supporting material head to let it entry into straightening roller smoothly, loading car is equipped with backup plate to prevent coil slipping off from loading car while moving little big distance, while hanging coil.
Loading car moving method: hydraulic motor.
Loading car lifting method: hydraulic method(controlled by pressure retaining valve, stable and reliable).
Moving method of backup plate for preventing slipping down: by manual.
Loading Car with Motorized Roller(for optional), easy for material head feed into straightener, prevent coil from loosening while loading coil and starting uncoiling specially for high strength high elasticity steel.

3.Straightener-Feeder part
Function instruction: use unbending principle to release material bending stress to straighten plate, then feed into press equipment according to set length and speed.
Driven method: AC servo motor
Straightening-feeding roller combination: straightening roller; assistant roller; feeding roller.
Straightening measure display method: dial display.
Straightning roller release method: pneumatic release.
Straightening measure adjusting method: manually by hand wheel (Electrically Adjust for optional)
Straightening measure adjusting method: electrically adjust (for optional), no need rotate the hand wheel, more precise, with date storing function to store each group of material of straightening adjustment date which can save time for future using， convenient for operation.
Roller material: GCr15.
Feeding line height adjusting method: electrically adjust, customized
Roller driven method: gear driving, all gears adopt tempering, carburization, high frequency quenching, precise grinding gear IT6 level precise standard.
Straightening-feeding rollers flip up system (for optional): upper straightening-feeding rollers can be lifted by hydraulic cylinder from one side, lifting angle can reach up to 30 degree. Through operating touch screen HMI or button of hand operating box to open straightening-feeding rollers, by this way, easy for clear rollers, to ensure material surface flatness and cleanliness. Adopts double oil cylinder to control.
The flip up system adopts one-key opening function, just press button on the operating panel then can open the upper straightening-feeding rollers head to clean rollers. While close straightening-feeding rollers, also adopts one-key closing function, which is very easy to operate. (picture for reference)
Hydraulic cutter(for cutting material head and end, for optional)
Driven method: hydraulic, double oil cylinder.
Cutting method: hydraulic undercut.
Oil lubrication system (for optional)
Oil lubrication system can single/double side painting oil uniformly, oil quantity can be adjusted, oil can be used circularly. Redundant oil can be oil returning system to return, via filter screen then through oil pump to supply oil mass.
Safety Fence (for optional)
Safety Fence is equipped with safety interlocks
2 Doors on operator side
1 door on rear side for maintenance
Safety light curtain at coil loading area
The working principle of the three-in-one decoiler straightener feeder machine:

it is a feeding system that integrates the decoiler, the straightening machine and the feeder. In the peripheral equipment series of press machine, it can be said that it is the apex performance of the straightening feeder machine. It is a feeding system that integrates the functions of the three common models into one body by digital technology. The working principle is organically combined by the following parts.
