Factory Supply Automatic A4 Paper Making Machine - GW PRECISION SHEET CUTTER S140/S170 – Eureka

According to GW product’s technics, The machine are mainly used for paper sheeting in Paper Mill, Printing House and etc, mainly process including: Unwinding—Cutting—Conveying—Collecting,.

1.19″ touch screen controls are used to set and display sheet size, count, cut speed, delivery overlap, and more. The touch screen controls work in conjunction with a Siemens PLC.

2. Three sets of shearing type slitting unit to have a high speed, smooth and powerless trimming and slitting, with quick adjustment and locking. High rigidity knife holder is suitable for 300m/min high speed slitting .

3.The fast/slow speed belt is controlled by the stepless frequency converter, which automatically tracks the knife speed and adjusts the belt speed, so that the paper can be perfectly overlapped. 

4. Upper knife roller has the British cutter method to effectively reduce the load and noise during paper cutting, and to extend the life of the cutter. The upper knife roller is welded with stainless steel for precision machining, and is dynamically balanced during high-speed operation.

Lower tool seat is made of cast iron integrally formed and cast, and then precision processed, with good stability.

Active roller surface is designed with expansion lines, and the cylinder is used to control the pressure and paper clamping of the roller body.

Rotary cutting knife is made of special alloy steel precision machining, with long service life and easy adjustment of the blade.Safety cover will automatically shut down when the safety cover is opened, ensuring safety.
