Continuous Rotary Cutter Dedicated Gearbox High Synchronization
Precision Burr-Free Cutting
Product Overview
This gearbox series is a core drive component specifically designed
for Continuous Rotary Cutters (also known as Rotary Shears or
Flying Saws). Its purpose is to precisely and synchronously cut
continuously extruded profiles—such as plastic rods, rubber strips,
profiles, paper, or film—into pre-set lengths. With its high
synchronization accuracy, exceptional rigidity, and stable
performance, this gearbox guarantees consistent cut lengths and
clean, burr-free cuts, making it a reliable solution for
high-quality continuous cutting production.
Key Advantages
1.High Synchronization Precision: Utilizes precision gears and optimized design to ensure strict
synchronization between the cutter head rotation and material line
speed, eliminating length deviations.
2.High Rigidity & Impact Resistance: Features a robust housing and high-rigidity gear shafts to
withstand instantaneous impact loads during cutting, maintaining
positioning accuracy over long-term operation.
3.Burr-Free Cutting: Smooth transmission and precise phase control ensure the blades
perfectly match the material at the cutting point, resulting in
clean cuts without flashes or burrs.
4.Easy Adjustment: The cut length can be easily adjusted by changing the speed ratio
between the servo motor (driving the feed) and the gearbox (driving
the cutter head), enabling quick changeovers for various product
specifications.
5.High Reliability: Employs high-quality bearings and seals with excellent dust and
water protection (IP65 rating), adapting to harsh environments with
low failure rates and extended maintenance intervals.
