500 r/min Mandrel Rotation Speed PET Strap Semi-auto Winder

The CQ800 semi-automatic PET strap winder features a maximum mandrel rotation speed of 500 r/min, providing ample mechanical capability for high-speed winding. When winding large-diameter packages, the rotation speed automatically decreases as the diameter grows to maintain constant linear speed (up to 250 m/min). The 500 r/min upper limit means the machine can easily handle high-speed production of small-diameter coils or maintain high productivity when the coil diameter is small. The mandrel uses precision bearings and dynamic balancing, ensuring smooth and reliable operation even at sustained 500 r/min. This parameter, together with the 350 m/min pickup speed and 50-250 m/min winding speed, forms the core capability for efficient winding.

• High rotation speed limit - 500 r/min, suitable for high-speed small-coil production.
• Constant linear speed control - Automatically reduces speed as diameter grows, maintaining constant line speed.
• Precision dynamic balancing - Smooth high-speed operation, low vibration.
• Wide speed range - From slow large-coil to fast small-coil, full coverage.
• Long-life bearings - Industrial-grade bearings, long maintenance-free intervals.
• Enables high pickup speed - 500 r/min makes 350 m/min pickup possible.
• Dual servo drive - Fast torque response, high speed accuracy.
