Working Principle and Characteristics of a Mobile Automated Batching System 

Wuxi Xielì Automation Equipment Co., Ltd. (hereinafter referred to as “Wuxi Xielì”)’s mobile automated batching system is its flagship product, specifically designed to address the complex batching challenges in the friction materials (brake pad) industry. 

The most significant innovation of this system is its departure from the conventional fixed “one silo, one scale” configuration. By employing a mobile weighing cart that travels along rails, the system enables “one vehicle to serve multiple silos.” Leveraging the academic expertise of its founding professorial team, the system boasts notable advantages in precision control and dust-proof design.

The following is a detailed technical analysis of the system: 

1.  Core operating principle: Mobile “one vehicle, multiple warehouses” 

The system typically features a three-tier, hierarchical architecture and employs wireless communication for control, enabling fully automated closed-loop batching: 

Ground Level (Mixing Layer): Install the mixer and receive material discharge from the batching carts. 

Automatic batching layer (core layer): Equipped with a mobile batching and weighing cart and associated tracks. The cart travels automatically along the tracks and positions itself directly beneath the designated material bin. 

Feed layer of the hopper (top layer): arrangement 20-100 A storage bin for holding various raw materials (such as graphite, iron powder, resin, etc.). 

Workflow: 

The ingredient cart automatically moves to the target storage bin. ->  The feeder (screw) below the hopper / Vibration / Belt) Cutting ->  Vehicle Dynamics / Static weighing ->  The trolley moves above the mixer. ->  Automatic unloading. 

2.  Four Core Advantages 

The reason why Wuxi Xielì’s system stands out in the industry (recently 40 (For domestic friction-material manufacturing enterprises) adoption is primarily attributable to the following advantages: 

A. Extremely high space and cost efficiency 

Equipment savings: While traditional solutions require dozens of scales, Wuxi Xielì needs only 1-2 A mobile cart can be used to weigh dozens of different materials. 

Reduced construction costs: Significantly lower steel structure and sensor expenses, coupled with a small footprint, making it particularly well-suited for the renovation of existing factory buildings. 

B. Professor-level algorithms ensure “high precision.” 

Technical Background: Leveraging the wireless communication and automated control algorithms developed by the founding team of professors from Jiangnan University, we have successfully addressed the issue of vibration-induced interference affecting mobile carts during the material-feeding process. 

Actual Performance: User feedback indicates that, after more than several years of operation, the system maintains exceptionally high and stable accuracy, effectively controlling dosage errors for trace additives. 

C. Fully enclosed “zero dust” design 

Dust-Proof Interfaces: In response to the high dust generation associated with friction materials such as graphite and carbon fiber, the cart is equipped with unique top-and-bottom dust-proof interfaces—featuring inflatable seals—that create a sealed enclosure during material loading and unloading. 

Environmental Compliance: By integrating negative-pressure dust collection, dust emissions are virtually eliminated, helping the plant meet environmental compliance standards. 

D. Intelligentization and Formulation Confidentiality 

Error-proofing Management: The system integrates a barcode-based error-proofing system that mandates verification of raw material batches to prevent incorrect material input. 

Data Security: Fully automated computer control ensures that ordinary workers have no access to specific formulation parameters, effectively safeguarding the company’s trade secrets. 

3.  Main System Components 

This system is primarily composed of the following components: 

Material Storage Bin: 20-100 It is equipped with a built-in arch-breaking and flow-assisting device to prevent material blockage. 

Ingredient Weighing Cart: It comprises the vehicle body, weighing system, wireless communication module, and drive system, serving as the “heart” of the entire system. 

Feeding system: Based on material characteristics (powdery / Granule / Fiber) Optional screw, belt, or electromagnetic vibratory feeder. 

Electrical Control System: Industrial PC +PLC , responsible for scheduling the trolley’s travel, processing weighing data, and generating reports. 

4.  Applicable Industries and Expansion 

Although the system originated in the friction materials (brake pad) industry, its technical characteristics give it strong cross-industry scalability: 

Refractory materials: It also faces the challenges of a wide variety of raw materials and high dust levels. 

Lithium battery materials: It is necessary to address contamination prevention and high-precision batching for both cathode and anode materials (requiring upgrading to stainless steel construction). 

Fine Chemicals / Color masterbatch: The issues of formulation confidentiality and trace-level addition must be addressed. 

5.  Summary 

Wuxi Xielì’s mobile automated batching system is, at its core, an intelligent solution that “encapsulates complex batching processes within a mobile robotic platform.” By leveraging “mobile weighing” technology, it addresses the pain points of traditional batching lines—high costs, large footprints, and significant dust generation—making it a quintessential “small but exquisite” champion product in a niche industrial segment.
