简体中文 I. Spatial revolution in the transformation of manufacturing
Jiaxing manufacturing industry is facing the double challenge of tight land resources and productivity improvement. In the factory building of the Future Industrial Park in the Jingkai District, theRing speed multiplier chain line through closed loop track designThis layout not only frees up 30% of shop floor aisle space, but also reduces the footprint of the line by 40% through the elimination of the traditional linear return section.Double Vertical Circulation Structure(e.g. the case of Tianneng Group's lithium battery production line), achieving a capacity density of 2,70% in a 6-metre-high plant.
Of particular interest is itsGravitational potential energy recovery mechanismThe return section is set up with 10°-15° inclined guideway, and the workpiece board relies on self-gravity to slide, with magnetic boost to compensate for kinetic energy loss, and the energy consumption is reduced by more than 30% compared with the traditional production line. This design is applied in Jiaxing electronics enterprises, saving more than 120,000 yuan in annual electricity costs (based on 100 metres of production line), which is in line with the core demand of the local "mu efficiency" reform.
Second, the technical core: the principle of speed multiplication and intelligent synergy
The core breakthrough of the ring speed multiplier chain line is theDeep integration of mechanical speed increase and digital control::
- Triple speed differential mechanism: Increased speed is achieved by the ratio of roller diameter (D) to roller diameter (d). When D=2d, the speed of the work plate reaches 3 times the speed of the chain (V=3V₀), while the actual speed of the chain is only 0.8m/s, which drastically reduces the effect of vibration on precision components.
- High-precision positioning systemThe technology reduces the defective rate of lens gluing from 2.3% to 0.4% in an optical lens factory in Jiaxing, which adopts proximity switches and photoelectric sensors to make the stagnation error of the work plate ≤±0.1mm.
- Dual Brain Control Architecture::
- edge node: real-time response at station level (e.g. RFID automatic switching of process parameters)
- central decision-making: PLC analyses tension sensor data to predict risk of chain breakage (accuracy 89%)
personal viewpointJiaxing enterprise's innovation lies in the "gravity drive" and "magnetic compensation" coupling - not only the use of natural forces to reduce consumption, but also through the electromagnetic field dynamic regulation to compensate for the instability of gravity, this "natural force - industrial energy" symbiosis mode may become a new paradigm for China's smart manufacturing. Regulation to make up for the instability of gravity, this "natural force - industrial energy" symbiosis mode, or will become a new paradigm for China's smart manufacturing.
III. Industrial adaptation: from electronics assembly to heavy manufacturing
Consumer electronics
Jiaxing ring doubling chain line shows significant advantages in laptop assembly:
- 750mm ergonomic height: Reduces operating fatigue with 28W energy-saving lamp illumination
- Conductive Wheels - Conductive Platoon Electrically Conveyed: Supports online testing to shorten time-to-market 30%
- Modular extensions: Increase or decrease the speed of jacking and lifting mechanism to adapt to the product iteration needs.
Upgrading of equipment manufacturing
At an engine plant in Xitang, a ring doubling chain line works in tandem with AGVs:
- Heavy Duty SolutionsSteel rollers for 2000kg cylinders, triple speed chain pitch for optimum balance of speed and strength.
- dynamic buffer: Arc segments use centrifugal force (0.3g) to hold the workpiece against the locating surface, reducing the amount of fixtures used.
Space-sensitive scenarios
For the renovation of old factory buildings in the city centre (e.g. South Lake Garment Factory):
- Double-deck ring + vertical lift: 1200m2 capacity in 800m2 space
- Optimisation of human-computer collaboration: Machines complete repetitive processes such as sewing, and workers focus on pattern adjustment, increasing per capita output by 35%.
IV. Future evolution: from energy-efficient factories to manufacturing in space
Current technology pain points are centred onMultiple physical field coupling interference::
- Accumulated maglev gap error of 0.15mm after 800 hours of continuous operation
- Electromagnetic brake resonates with centrifugal force causing positioning drift
The direction of the breakthrough of Jiaxing enterprises has been clear:
- quantum gravity sensor: MEMS chip real-time monitoring of local gravity changes, dynamic calibration of control parameters
- superconducting energy storage orbit (physics)YBCO Coated Rail Lab Data 99% Potential Energy Recovery Rate, Towards a "Zero Power Plant"
- Off-site manufacturing tests: Collaboration with Shanghai Aerospace Academy to develop a 200m diameter circular space station production line, using rotation to generate 0.8g artificial gravity
Exclusive dataIn 2028, Jiaxing is expected to build the first "30-metre gravity potential energy spindle" demonstration line - relying on the geographical characteristics of the Hangzhou-Jiaxing-Huzhou Plain, generating a continuous driving force through the difference in building heights, and completely reconfiguring the logic of energy consumption in production. The first 30-metre gravity potential energy spine will be built in Hangjiahu Plain.
Self-questioning: a breakdown of the core issues
Q1：Why do Jiaxing enterprises prefer circular to linear multiplier chains?
A: At the heart ofDouble optimisation of space and energy consumptionThe circular layout eliminates empty return trips and saves 40% of space. The circular layout eliminates the empty backhaul and saves 40% of land; the gravity backhaul section reduces energy consumption by 30%; and it is more suitable to meet the demand for vertical space intensification under the policy of "industrial upgrading" in the central city of Jiaxing.
Q2: How do triplex chains combine efficiency and shock resistance?
A: DependencePhysical properties of mechanical speed increasesThe actual speed of the chain is only 0.8m/s. When the work plate needs to be conveyed at 2.4m/s, the actual speed of the chain of triple speed chain is only 0.8m/s, which greatly reduces the vibration transmission of the chain; meanwhile, the engineering plastic roller (μ≤0.05) further absorbs the high-frequency vibration.
Q3: Which industries are taking the lead in scaling up applications in Jiaxing?
A: Three major areas lead the way:
- New Energy Battery(Tennant Group double line)
- optical instrument(South Lake Lens Factory ±0.1mm positioning)
- intelligent clothing(Human-computer collaboration to improve 351 TP3T output per capita)
The localisation case shows that the average logistics efficiency of the enterprise has increased by 421 TP3T and site utilisation by 281 TP3T.
