Import Automatic Paper Roller Slitting Machine — Buy in wholesale FOB from Supplier in China

The RYSD-1500 and RYSD-1800 automatic paper roller slitting machines from Hangzhou Royal Packing Machinery Co. Ltd. process rolls at maximum widths of 2600mm and 3000mm respectively, with corresponding maximum diameters of 1550mm and 1800mm. Minimum input diameters differ at 400mm for the RYSD-1500 and 600mm for the larger RYSD-1800. Cutting six volumes per hour on average, each roll consumes 3 to 6 minutes depending on weight, driven by a 30kW main inverter motor on the RYSD-1500 with total installed power of 40kW, rising to 47kW on the RYSD-1800.

The alloy blade measures 1850 by 12mm with an 80 chromium saw body and Taiwan-made saw head, processed for dynamic balance and heat treatment. A Japan NSK reduce gearbox bearing set with NOK high-temperature seal ring supports the mechanical drive, while the paper stand uses a 2.8m length, 194mm diameter, 25mm thick shaft roller. Two high-stability inner vacuum negative pressure fans claim an 80% dust reduction. The machine frame is full-welded iron constructed to GB standard, with machine transmission shafts and mechanical parts produced on digital controlled lathes for precision.

Intended users include paper converters, corrugated board plants and industrial packaging facilities slitting parent rolls into narrower reels for downstream processing. The RYSD-1500 at 4.5 tonnes and 4500 by 3000 by 2500mm suits moderate throughput lines, while the RYSD-1800 at 4.8 tonnes and 7000 by 3500 by 2800mm addresses larger format requirements. Voltage is 380V/50Hz with custom design available. Buyers should confirm which model matches their parent roll inventory and clarify blade sharpening intervals, replacement after six polishings, and vendor contact details with Hangzhou Royal Packing Machinery Co. Ltd. directly.
