Features of of Uncoiler Straightener Feeder
● Reliable Structure Design
Super large scale and plenty of advanced quality control measures including CNC machining, grinding machine, boring machine and Lathe machine equipment and various precision testing instruments from Germany, Japan and Taiwan. It can ensure the high precision and quality of all parts of machine.What's more, all of main body makes surface treatment with our shot blasting machine before they are painted. With our shot blasting machine treatment, the machine surface is excellent for painting.they blast onto the surface of work piece with shots to clean and beautify the surface. The shot blasting also enhances the pressure stress of work piece surface and extends the lifespan.We also use high-end vehicle oil paint for our machine to have high level of painting quality and you don’t need to worry about broken painting problem under extremely nasty working environment.
● Modular control, simple and smart operation
SunRui MFL series compact coil feed line is not only a simple integration of decoiling, leveling and feeding machine into one unit, but also emphasizes highly integrated control in control operations.The control of the material decoiler hydraulic station, the hydraulic coil car, the decoiler driven motor, the inverter and the feeding servo system are all connected with the PLC control module system and the basic parameters can be set up in the touch screen. The simple digital control of the 7-inch high-precision touch screen makes the use of the compact coil feed line adjustment machine very simple and convenient, and the degree of intelligence is extremely high.
● Space saving and easy installation and low maintain
SunRui MFL series compact coil feed line save space structure designed is not only a simple integration of decoiling, leveling and feeding machine into one machine, but also emphasizes highly integrated control in control operations.it can achieves simple operation, low maintenance, complete functions, energy saving and high completeness.
● High precision straightening and feeding performance
For the separate independent type decoiler straightener feeder machine, there will be a loop between each machine, means that all of them need an inverter for speed control and single of sensor for movement, even so, the movement will not be fully synchronized, which will affect the precision of feeding. Decoiler straightener feeder coil feeding line can synchronize these three parts, and be controlled by high precision servo driven and PLC system, which ensure a high servo feed accuracy.

Main Parts of Uncoiler Straightener Feeder
Coil Car
● Coil car is one of the optional for the customer, It is installed on the side of the decoiler part, and can automatically feed the coil into the straightener-feeder accurately and fastly.
● Wear-resisting loading surface through the sand blasting process.
● Safety arms to prevent coil falling.
● Hydraulic cylinder drive the coil car lifting up and down.
● Hydraulic motor drive the coil car move forward and backward.
● Remote button control and touch screeen control
Uncoiler Machine
● The uncoiler is designed for coils with an outside diameter of up to 1200mm. The coil is placed on spindle and expanded manually.
● Spindle expansion range: Φ470-Φ520mm.
● Decoiler is Driven is by AC motor with an inverter
High Precision Straightening and Feeding Machine
● The straightener feeder parts is straightening the coil strips and feeding it into the stamping press and dies according to the fixed length controlled by PLC.
● Given the difference in coil at the beginning of rollers and the end of roller, it is usually necessary for an operator to always be monitoring straightening operations, and to manually carry out corrections to ensure a high degree of precision in straightening.
● Straightener Roll Material :GCr15 ,Thickening plating and Gringding processing. Hardness :HRC58-60°, roller surface is done plough electroplating processing.
Discharging Support Bracket
● The outlet support bracket is used to deliver the straightening strips to press die smoothly.
● When the coil material is thin thickness or soft material , or the distance between straightener-feeder and stamping dies is
long, the strip can not be delivered the strip head into the die successfully, the support bracket will help to reach it.
● The length of the support bracket is adjustable to meet different dimensions of stamping press machine and dies.
Automatic Lubrication Unit (Option)
● Lubrication of steel strip before stamping will protect the stamping dies from damaging and prolonging the uselife.
● The automatic lubrication system is automatically controlled, with an oil loop recycling system, which will save oiling cost and prevent leakage.
