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.
