Double-deck Speed Chain Pallet Conveyor: The Intelligent Logistics Engine for Space Reuse

• ​differential drivePallet speed = chain speed x (1+D/d), where D is the diameter of the roller and d is the diameter of the chain roller. 2.5 times the speed of the chain has a D/d ratio of 1.5, which increases the pallet movement speed to 2.5 times that of the chain.
• ​Dynamic Reflow Architecture: After the upper level has finished conveying, the empty pallet passes through thejacking and panning machine(Cylinder Drive + Linear Guide) Automatically transfer to the lower return line, reducing the 40% flat surface area.
• ​Accumulation control technologyWork stations are equipped with photoelectric sensors and blocking cylinder linkage, response time ≤ 0.5 seconds, to achieve millimetre-level stopping accuracy, allowing local pause without interrupting the whole line of operation.

​personal viewpoint: The current return buffer design is still a technical shortcoming. Ningbo Kai Feng 2024 patentedPolyurethane cushioning modulesAlthough it is able to absorb 60% shock energy, it needs to be transferred to a futureHydraulic Damping Adaptive SystemUpgrade - Dynamically adjusting the damping force through real-time monitoring of the falling speed can further reduce the wear and tear on the 32%'s mechanism.

II. Structural innovation: a balancing act between modularity and heavy loads

​1. Modular architectural innovation​

• ​Pre-set profile systemAdopt 118×100mm standard aluminium profile guide rail, support 300/600/900mm module fast splicing, splicing error <0.1mm/m
• ​Driver Compatible DesignMotor interface: Siemens/Mitsubishi multi-brand flange, control box integrated Profinet/EtherCAT protocol, plug-and-play.
• ​Quick release link technologyPatented snap link changeover time compressed from 45 minutes to 8 minutes, dramatically reducing lost downtime.

​2. Heavy-duty performance breakthrough​

Note: Heavy-duty scenarios need to be equipped with transition rails (wear resistance is 300% higher than aluminium rails) to prevent chain deformation.

III. Industry application matrix: pain point cracking programme

​electronics manufacturing(Mobile phone/laptop assembly)

• ​Static control: Tray-integrated conductive wheels (surface resistance ≤ 10⁶Ω) to prevent chip breakdowns
• ​Quick changeover: Modular tooling boards for 2-hour product model changeover, supporting 12 models in daily production

Self-questioning: the three centres of decision-making on the ground
​Q1: When should I choose a double-layer over a single-layer doubler chain?​

A: Three conditions need to be met at the same time:

​Factory rent＞800RMB/m2/year(18 months to recover incremental cost of steel structures)
​Daily output >5000 pieces(Avoiding extended ROI cycles due to idle equipment)
​Presence of heavy parts >300kg(Load limit of single layer chain is only 300kg)


​Q2: How to ensure the stability of operation in humid environment?​


A: Triple protection strategy:

​Material upgradeCarbon steel chain + sealing cover, life expectancy is 200% higher than the standard model.
​Load-bearing correction: Load = Nominal value × e^(-0.03 × humidity %) (e.g. 300kg chain at 70% humidity with an actual limit of 240kg)
​Electronic control protection: IP54 rated control cabinet + earth leakage switch response <0.1 sec.


​Q3: What signals indicate that the system needs urgent service?​

A: Three major danger signs:

​Workpiece jitter >±0.3mm(Electronic patch defect rate soars threefold)
​Average monthly tensioning adjustment > 2 times(Indicates track deformation or chain link wear)
​Bearing temperature continuously >85°C(doubles the risk of lubrication failure)



Future Evolution: The Integration of Carbon Fibre and Adaptive Systems
​Carbon Fibre Rollerof laboratory data revealing new directions:

Reduced weight 68%, growth rate ratio exceeds 4.2 times limit
Noise reduced from 82dB to 71dB (at 3.5x speed)

Current bottleneck is cost (7 times that of steel parts), but 2026Composite material injection moulding processThe cost is expected to be compressed to 2x after mass production.


​Exclusive Prejudice: With the popularity of tension adaptive system (strain gauge + AI real-time regulation), high-end production lines will be realised:

Energy consumption reduced by another 17% and chain life extended by 3.2 times.
Dynamic speed response <0.2 seconds, completely eliminating the start-stop shock.
