Double-deck Speed Chain Conveyor: New Paradigm of Space Folding and Intelligent Conveying

• ​upper chain of productionConveying of loaded pallets at multiplied speeds (2.5-3 times) in the range of 2-20 metres/minute;
• ​Lower empty board return channelSave 58% horizontal space by forming a closed loop between the load shifter and the jacking mechanism;
• ​Vertical Circulation ModuleSeamless "conveyor-return" to avoid the time-consuming problem of off-line turnover of tooling boards.

​personal insightThis design is actually an industrial expression of "space-time compression" - reconfiguring the production line through physical structures. For example, in a 24-metre production line in an automotive parts factory, the structure reduces assembly man-hours by 351 TP3T, demonstrating thatThe multiplier effect of space efficiency on manufacturing effectiveness.

​1. Innovations in heavy-duty bending technology​

For heavy-duty scenarios of 8 tonnes or more, such as automotive manufacturing:

• ​Double Axial Bearing Housing: Vertical load bearing (800kg/point) decoupled from horizontal rotation, eliminating the risk of tipping;
• ​Dynamic equilibrium of magnetorheological fluids: Inter-axis filling with magnetic particle fluid (viscosity 0.1-1.2 Pa-s), real-time compensation of speed difference, heavy load offset <±0.3mm;
• ​Staggered sprocket layout: 30°+60° composite turning design, turning radius compressed to 400mm, saving 52% space compared to traditional right-angle steering.

​2. The cleaner materials revolution​

Meets GMP Class B standards for the pharmaceutical/food industry:

• ​Stainless steel-ceramic composite rail: 3mm substrate + 0.2μm ceramic coating, friction coefficient reduced by 40%, 3 times longer life;
• ​Negative pressure adsorption channel: -65kPa vacuum eliminates particle lifting and CIP cleaning coverage of 99.2%;
• ​Anti-static Workwear Plate: Surface roughness Ra≤0.4μm, ESD damage rate reduced to 0.15%.

​3. Intelligent energy consumption game model​

Dynamic power regulation through torque coupling algorithms:

make a copy of
ΔT = K × (V theoretical - V measured) × D / (9550 × η)  
(K = 1.2-1.5 attenuation factor, D roller diameter, η transmission efficiency)

After the application of a photovoltaic plant, the energy consumption in the bending area was reduced by 281 TP3T, and the speed fluctuation rate was pressed to below 0.91 TP3T.
