Performance And Characteristics:

Main Machine Parts Specification: 

Main Unit Function description

1.Unwinder device

(Shaftless loading system : diameter in picture can be 700mm, )The unwinder adopts SMC proportional valve controller ,automatic hydraulic loading system

2.EPC Control system : (Made in Tainwan) Adopt Servo motor control and static correction system

With CCB sensor control the edges or printing lines (Tainwan brand)                  

3.Cutters:The machine can be with two way of cutter for different material

( Razor and Round cutter) The distance of the cutters is adjustable

4.Paper core positioning by laser for convenient operation

5.PLC Siemens Control

(Automatic Tension Control,Meter Counting,automatic stop before jumbor roll is ending )

The language can be Chinese and English

6.Rewinding with high quality friction shaft

  1)Unwinding part 

1.Adopts shaftless hydraulic fixing system, easily for one person   operation. Using special conic node system, protect the inwall of paper core. Have durable 3” mechanical locking system. 2 pcs of hydraulic clamping oil cylinder moves to each side at the same time, easily operation.

2.2pcs of hydraulic type loading and unloading material oil cylinder can bear 2T material to save the manpower and time.

3.It does not need to input the material thickness, the proximity switch can inspect the unwinding diameter directly which near the transmission shaft. The machine can slow down according to the rest material, in this way, the worker can prepare for the next roller.

4.Automatic error-correction for the edge position is controlled by the CCD photographic system. The whole frame adopts guide way type to move left and right which driven by the Italy servo motor. The moving part uses thread screw.

5.Pneumatic material connecting device, with the square steel structure, adopts the way of pneumatic and rubber pressing roll to save the material Corridor type feeding materials Unwinding pneumatic brake by shanghai brand

2)Traction part

The 4KW servo motor drives the mirror surface and pinch roll

3)Waste paper recovery device

Using motor to blow out the waste paper. The net cage should be prepared by customer.

4)Rewinding part:( It decided by customer if the product come out from the left or right)

1)  Rewinding the cut material by left and right double bearing.

2)Each bearing with 1 set of 5.5KW servo motor to drive the air shaft. The tension decided by the roll diameter. PLC controls SMC electric automatically to make all the sheet same thickness when do the multiple slitting. Because of the press roller, all the reels end face is smooth. it has the choice of pneumatic press roller and self-weight press roller. The screw type rewinding way can control the degree of the tightness of the finished products. With the increasing of the rewinding diameter, the servo motor speed goes down to extend the life of the air shaft.( it is never broken except the human factor)

It can choose the whole shaft tension with out slip frequency and the servo motor in torque control mode in PLC
