Bozhou Ring Multiplier Chain: Intelligent Transformation of the Industrial Growth Engine

###I. Core Principles and Ring Design of Multiplier Chains
The mystery of the "growth rate" of the multiplier chainStems from its unique physical structure. When the chain is travelling at a constant speed, the top work plate can move up to 2.5-3 times the speed of the chain. This effect is achieved byDifference in diameter between roller and roller realised-If the roller diameter (D) is much larger than the roller diameter (d), the speed of the work plate (V)_{catch sight of in a doorway (old)}
) and chain speed (V_{cable length (= 1}
) of the relationship for:
V_{catch sight of in a doorway (old)}
= V_{cable length (= 1}
× (1 + D/d). For example, when D/d = 2, the speed of the work plate is three times that of the chain. In practice, due to friction losses, the growth rate is slightly lower than the theoretical value, but still the core of the assembly line efficiency jump.

Structural innovations in ring doubling chainsEmbodied engineering optimisation of closed-loop systems:

connection method: The use of side plate bolting (for small and medium-sized wire bodies, for easy disassembly) or side plate pinning (for large wire bodies, for high load capacity) ensures that the chain creates a seamless loop within the aluminium profile guide;
Tooling Board Cycle Design: Automatic line turning and vertical circulation of the workpieces by means of jacking translators and double-layer rotating transition devices, avoiding manual intervention;
Anti derailment mechanismThe rollers protrude 2mm from the guide rail, reducing the risk of foreign objects getting stuck and maintaining conveyor stability.

###Second, Bozhou industry application mapping: from traditional medicine to new energy wave
Bozhou, as the town of traditional Chinese medicine industry, has accelerated its layout in the field of industrial automation in recent years, and the penetration rate of ring doubling chain has increased significantly:

Pharmaceutical and Food Processing
- The filling line applies stainless steel speed doubling chain, which meets the GMP hygiene standard and solves the Pharmaceutical liquid filling in thePrecision parkingQuestion;
- The function of accumulating and placing the workpiece board (stopper control stopping time), adapting to different dosage forms. Packaging beat, such as Bozhou, a traditional Chinese medicine enterprises to achieve filling efficiency by 30%.
New Energy and Electronics Manufacturing Breakout
- Lithium battery production line adoptsAnti-static ChainSynchronised control with PLC to avoid electrode material damage;
- Combined with RFID identification technology, a photovoltaic module factory in Bozhou realised a sorting and conveying system of 8000 cells per hour. 8000 cells per hour in a PV module factory in Bozhou.
Sample of traditional industry upgrading
- Bozhou automotive parts factory introduces looped two-speed chain with 200kg load/station PassingServo positioning stopper(Accuracy ±0.5mm), solving the fine-tuning problem of engine block assembly, and shortening the beat by 20%.

###Third, the technical advantages: why Bozhou enterprises choose ring doubling chain?
- Balancing efficiency and resilience
Quick change of pallets supports mixed line production (e.g., multiple models of appliances), and chain Low-speed operation reduces energy consumption, while high-speed movement of pallets maintains throughput.

- Intelligent upgrading of the underlying logic
Bozhou plant passedMitsubishi PLC+MES systemIntegration, real-time tracking of the position of the workpiece board, with automatic loading and unloading of robots, and the gradual realisation of the "black light factory".

- cost controllability
Aluminium profile guide rails and modular design shorten the installation period, and maintenance only requires regular additions. Maintenance only requires regular grease lubrication of the chain, lower maintenance costs than traditional conveyor lines 40%.

###IV. Challenges and Countermeasures for the Transformation of Bozhou's Smart Manufacture
｜Selection MistakesSome enterprises blindly pursue "triple-speed chain", but ignore the light load scenarios (such as electronic assembly) for single-speed chain + servo drive is more economical.
｜Maintenance pain pointsBozhou high dust environment easily lead to roller jamming, need to increase the guide rail dust cover with quarterly cleaning process.
｜Talent GapThe operation and maintenance of intelligent control systems relies on professional engineers, and a localised training platform is urgently needed.

###V. The future: the Bozhou programme under Industry 4.0
Bozhou's ring speed chain is moving from a "single conveyor" to a "single conveyor".Systematic production hubsEvolution. One company piloted a "digital twin production line", which uses sensors to monitor chain wear coefficients and predict failure cycles; other factories are exploring the possibility of a "digital twin".jacking panners + AGV synergyIn addition, the company has broken the limitations of the linear assembly line and built a flexible workshop. Under the guidance of industrial policy, Bozhou may become a small and medium-sized cities "low-cost intelligent" model - with minimal investment to activate the traditional production line genes, rather than the blind pursuit of unmanned.

>>> Self-questioning: Bozhou enterprises are most concerned about 3 questions
Q1: What is the essential difference between a ring doubler chain and a suspension chain?
>A: Multiplier Chain DependencyIncremental roller structureTo achieve high-speed conveyance of the workpiece plate, suitable for ground station assembly; suspension chain through the hook air transmission, good at heavy parts continuous production (such as car chassis). Bozhou pharmaceutical industry choose the former because of the need for workstation stay filling, auto parts factory choose the latter because of continuous welding beat.

Q2: How to take advantage of the ring when the length of the production line is limited?
>A: A factory in Bozhou usesDouble Vertical Circulation Design: The lower level conveys empty work plates back to the starting point and the upper level runs full, increasing space utilisation by 60%.

Q3: How long is the payback period?
>A: Taking Bozhou lithium battery line as an example, the multiplier chain system accounts for the total cost of equipment 15%-20%, but usually payback within 14 months due to efficiency improvement and staff reduction effect. The key is in matching capacity planning - below 500 pieces/day is not recommended.
