I. Core Technology: The Mystery of Speed Stacking
The core of Fuzhou Ring Speed Chain Production Line lies in its uniquevelocity superposition principle. Through the difference in diameters of the rollers and rollers (D > d), the actual movement of the workpiece can be 1.5 to 3 times the base speed of the chain. For example, when the roller diameter is 2 times that of the roller, the speed of the pallet is 3 times that of the chain (V total = V₁ × (1 + D/d)). This design makes the material conveying efficiency increase dramatically, and at the same time maintains the stability of the chain running at low speeds and reduces wear and noise.
II. Structural design: balance between lightweight and toughness
Fuzhou manufacturers (e.g. Guanrui Industry) adoptSpecial aluminium alloy profileAs the main body of the guide, combined with triplex engineering plastic chain, to achieve the unity of light weight and high strength. Typical structures include:
- modular component: 118 x 100mm aluminium profile rail, 40 x 40mm adjustable kickstand, 3mm steel plate folding stopper, supports quick assembly and customized extension.
- multifunctional integration: The line body integrates power/gas dual pipe line trough (6-point gas pipe), 28W energy-saving lamp holder and acrylic document signage to meet the needs of integrated production, lighting and information management.
- environmental adaptation: Aluminium alloy structure is resistant to high temperature dust, special scenarios (e.g. heavy manufacturing) can be replaced with steel frames to expand the application boundaries.
III. Intelligent control system: precise beats and flexible scheduling
pass (a bill or inspection etc)PLC control technologyThe system enables the dynamic regulation of the workpiece boards:
- Workstation Synergy Mechanism: Black and white buttons are provided at each station. The black button triggers the stopper to descend, guiding the workpiece board into the jacking and shifting mechanism; the white button controls the roller steering, sending the empty board back to the staging area, forming aClosed-loop material flow.
- 积放功能: Blocker with cylinder delay (3 seconds) to achieve accurate stationing of the workpiece plate, allowing specific stations to be assembled or inspected, while other stations continue to flow, improving line utilisation.
- Path optimisation: Combining elevators and right-angle transplanters, it supports double-layer cyclic conveying or planar steering, reduces downline turnover, and improves space efficiency by more than 40%.
IV. Industry applications: from consumer electronics to heavy manufacturing
Fuzhou ring doubling chain has penetrated many fields:
- consumer electronicsFor computer mainframe/notebook assembly lines, carrying lightweight components such as circuit boards and adapting to variable speeds of 2-20 metres per minute.
- home appliance manufacturing: The air conditioner/TV production line takes advantage of its high-temperature resistance to synchronise assembly and aging tests through double-layer conveying.
- Heavy machineryEngine assembly line adopts a steel structure with a speed chain, and the load capacity of a single plate is up to 2,000kg, which overturns the traditional perception of "light load only".
V. Safety and maintenance: full life-cycle management
safety normIncludes 7 mandatory measures such as emergency stop button protection, power failure and maintenance.Maintenance PointsSpotlight:
- The gearbox has a 3-month initial warranty period, followed by annual lubricant changes to avoid excess (which causes the generator to trip) or insufficiency (which leads to strangulation).
- Regularly check the chain plate curvature and tensioning device to prevent runaway failure.
VI. Future trends: integration of green manufacturing and Industry 4.0
Personally, I believe that the Fuzhou multiplier chain technology will break through in two directions:
- Energy consumption optimisation: Introduction of recycled aluminium guide rails and inverter motors in response to the "dual carbon" target.
- digital twin: Real-time monitoring of chain wear factor and speed deviation via IIoT, predicting maintenance intervals and reducing unplanned downtime (the current industry average break-fix time is 4 hours, which is expected to be compressed to 30 minutes in the future).
Self-questions and answers about Fuzhou ring doubling chain
Q1：What is the unique value of "accumulation function" of Speed Chain compared with traditional conveyor line?
A: The accumulation function allows the blocker to pause the workpiece when the chain is not stopped, realising "local pause, global flow". For example, the assembly station can stay for 10 minutes to complete the precision installation, while the inspection station continues to convey, eliminating the waste of waiting on the production line and improving the overall efficiency by about 25%.
Q2: Why do companies in Fuzhou commonly choose aluminium alloy as the main material for wire body?
A: Aluminium alloy has both light weight (60% less than steel) and corrosion resistance, suitable for clean environment in electronic factories; and the market has standard profiles such as 118×100mm in stock, which can shorten the delivery cycle to 2-3 weeks, and reduce the overall cost by 15%.
Q3: How does the material of the work plate affect the performance of the production line?
A: Aluminium tooling boards are suitable for high-temperature soldering scenarios, PVC boards have anti-static properties to protect precision chips, and double-layer rotary tooling boards are compatible with different sizes of materials - wrong selection may lead to deformation or static damage, and customised matching is key.
