Function description

Unwinding part

50. ► Adopts shaftless hydraulic fixing system, easily for one person   operation. Using special conic            node system from 3” to 6” for durable using. The 2 sides clamping arm are controlled by the                hydraulic dovetail groove linear guideway. 2pcs of hydraulic clamping oil cylinder moves to each          side at the same time, easily operation.
50. ► 2pcs of hydraulic type loading and unloading material oil cylinder can bear 3T material to save the       manpower and time.
50. ► 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. The unwinding tension adopts        the sensor close-cycle automatic tension, controlled by PLC.
50. ► With the manual adjustment system, the unloading material tightness can be controlled. The                 adjustable range: +/-20mm
50. ► 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 servo motor.            The moving part uses thread screw.
50. ► Pneumatic material connecting device, with the square steel structure, adopts the way of                     pneumatic and rubber pressing roll to save the material
50. ► Bridge type feeding materials
50. ► The unwinding adopts the Italy pneumatic braking.
50. ► Precision proportional valve use SMC

Main body part

50. ► The bare frame uses the 80# casting material, easily for dismounting and transportation.
50. ► The transmission combines the servo motor with synchronous wheel speed ratio.
50. ► Automatic traction device adopts pneumatic pressure way. The servo motor drives the mirror roll.
50. ► Close-cycle vector control.

Rewinding part

50. ► With double structure of surface rolling and center rolling, rewinding by front and back(A/B shaft),         double air shaft way( also can be single rewinding).
50. ► Clamping arm uses imported dovetail groove linear guideway
50. ► The rewinding shaft clings to the steel shaft( the steel shaft is driven)
50. ► Each bearing with 1 set of 18.5KW servo motor to drive the air shaft. The tension decided by the        roll diameter. PLC controls frequency converter automatically to adjust the tension of the air shaft        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 degree of the tightness of the finished products can be adjustable. With the increasing        of the rewinding diameter, the servo motor speed goes down to extend the life of the air shaft.
50. ► It also can choose the whole shaft tension and the servo motor in torque control mode in PLC
50. ► Discharging type: automatic hydraulic
50. ► Waste paper recovery device: Using motor to blow out the waste paper more than 20m. (also can       choose the automatic tatter function). The net cage should be prepared by customer.
