Single-layer reflux system with multiplier chain: a smart leap forward for planar conveying

One.Differential Principle: Physical Reconstruction of 2.5x Speed​

At the heart of the Speed Chain Single Layer Reflux System lies theDesign of roller to roller diameter ratioThe chain runs at the base speed, while the workpiece plate is able to travel at 2.5 times the speed. This phenomenon followsVelocity jump equation::

• ​V_{tooling board}
  = V_sprockets
  × (1 + D/d): Theoretical 2.5 times speed when the roller diameter (D) is 1.5 times the roller diameter (d).
• ​Friction Compensation TechnologyHigh-precision rollers with graphene-coated guide rails, which reduce the actual sliding rate to ≤5%, offsetting friction loss.
• ​Gravity energy efficient designThe 3° inclined return section allows the empty plate to glide under its own weight, reducing energy consumption by 22% compared to motor drives.

​Industry InsightAfter a sensor factory in Suzhou downgraded a 3x chain to 2.5x, the chain wear rate was reduced by 40% while maintaining a conveying speed of 18m/min - confirming that the"The essence of efficiency is not the pursuit of extreme values, but sustainable optimal solutions".
