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

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.

Key Features
  • 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.
Frequently Asked Questions
Is 500 r/min a typical operating speed?
When winding small-diameter coils (e.g., at the initial core diameter of 406 mm), the mandrel needs about 500 r/min to achieve 250 m/min linear speed. This is within the machine's design capability for long-term operation.
Will there be significant vibration at such high speed?
No. The mandrel assembly is dynamically balanced, and the machine frame is rigid. Vibration is minimal at 500 r/min and does not affect winding accuracy.
As the coil diameter increases, the rotation speed drops - does that affect production rate?
No, because linear speed remains constant (e.g., 250 m/min), so the time to wind each meter of strap is unchanged. High rotation speed is only needed when diameter is small, precisely to maintain constant line speed.
Does 500 r/min affect bearing life?
Bearings are selected for the rated speed. 500 r/min is within their design life, and under normal use they will last for years without replacement.
Why is such a high mandrel rotation speed needed?
To achieve a maximum linear speed of 250 m/min with a large core diameter (406 mm), the initial rotation speed must be about 500 r/min (n = v / (π*D)). Without this speed, 250 m/min would be impossible.
