Machine Introduction

Robust structure (steel plate thickness 60/80mm) to enable machine run high speed stably without noise and vibration, one rewinder structure with shaft-less (with different chuck sizes) simple operation, 5pcs pneumatic knife with optional automatic knife positioning system, Heavy duty shaft-less unwinder to bear big paper rolls weight up to 3.5-5Ton, automatic material loading, Optional automatic roll centering, automatic web guide, optional automatic web pass, automatic tension control, automatic unload, automatic stop by set of diameter or meters. Servo motor, ABB /Siemens inverter, 12inch HMI, Siemens PLC, pausource web guide, Schneider/Omron relay, SMC and Airtac pneumatic parts.

Utility Model Patent: ZL2023213258533

Advantages and Characteristics

The machine adopts PLC, synchronous control of servo motors, surface rewinding method;
The machine adopts ABB Inverter to speed regulation to keep running smoothly during acceleration;
Automatic meter counting, automatic stop of material run out, technical setting log are available;
HMI operation, Optional-remote assistance available through wifi/internet cable connection;
Unwind adopts Heavy duty hydraulic automatic shaft-less structure to bear the heavy jumbo reel in different core size easily, automatic material loading and lifting which provides reliable safety to operator, automatic web guide by ultrasonic sensor (Pausource/option EL brand) to achieve an excellent rewinding performance;
There are 2 pressure sensor on the guide roll,which will provide continuous and accurate Tension Control feedback. The control logic, handled by PLC, should be automatic degressive tension control, winding tension is automatically controlled by PLC according to the parameters set by the slitting process requirements and the change of the winding diameter, automatic control according to the digital taper & constant tension mode;
Adopt pneumatic circular blade and automatic blade positioning system to make adjustment of various slitting width much easier, safer and faster;
Automatic unload to make production easier and more convenient;
Shaft-less / shaft rewind structure for multiple slitting rewinding requirements;
Dynamic balance treatment for aluminum transmission roller;
