The Yangtze River Delta manufacturing upgrading wave, Jiaxing electronics and electrical appliances, mechanical and electrical equipment and other industries face the double pressure of rising land costs and production efficiency bottlenecks. The traditional single-layer conveyor line occupies a large area and the pain point of redundant process connection has given birth to theInnovative breakthrough in localised double-layer speed chain technology--Through vertical space reuse, the production capacity can be increased by 1,20% under the same area. e.g., the factory in Jiaxing Future Industrial Park adopts the double-cycle mode of "Upper Assembly + Lower Return", and the workpiece boards are assembled through the "Upper Assembly + Lower Return".Automatic transfer of jacking lifts, reducing manual intervention by 37% and becoming a benchmark paradigm for regional intelligent manufacturing. This technological innovation hits the cost pain point of Jiaxing's industrial land with an average price of over 150 RMB/m²/month, providing intensive solutions for intensive enterprises.
▍技术内核：差速机制与双层协同的精密平衡
The Engineering Intelligence of the Differential Principle
The core value of the Speed Chain stems fromDesign of roller-roller diameter difference::
- Internal chain roller(diameter d) rolls on the guideway, providing a base velocity V₁
- External Chain Roller(Diameter D>d) Rotation generates additional velocity V₂
- Actual speed of the work plateVₜ = V₁ × (1 + D/d)
By adjusting the D/d ratio (1.5~3 times), the material conveying speed can be as high as the chain speed.2.5 to 3 timesIn order to achieve high speed flow in low wear state. Take the production line of Jiaxing Takano as an example, when D/d=2.5, the speed of the workpiece plate reaches 7.5m/min, which is 200% faster than that of the single-layer line.
