Wuxi Xie Li Automation Equipment Co., Ltd. ( Wuxi Xielie ) With many years of deep expertise in the friction materials, refractory materials, and powder metallurgy industries, its mobile automatic batching system—commonly referred to as a “mobile batching cart” or “…” AGV/RGV The “Ingredient Vehicle” system is the company’s core flagship product.

Compared to traditional fixed batching systems, Wuxi Xielie’s mobile system offers the following significant advantages when dealing with production scenarios characterized by multiple product varieties, small batch sizes, high dust levels, and complex formulations:

1.  Extremely high space utilization and layout flexibility

“One vehicle for multiple uses, shared material bin”:

Traditional pain points: Fixed systems typically require a separate weighing hopper and complex discharge structure for each mixing line, occupying a large amount of workshop space.

Synergistic Advantage: A single or multiple mobile carts shuttle beneath an entire row of hoppers. Dozens, even hundreds, of hoppers can be served by just one weighing system (cart). This significantly saves floor space, making it particularly suitable for facilities with limited floor area or those requiring dense storage of various raw materials—for example, friction materials often require... 30-50 A company that uses raw materials.

Flexible scaling:

If new raw materials or new mixers are added in the future, all that’s needed is to extend the track or increase the number of carts—there’s no need to restructure the entire bottom of the hopper. This results in low modification costs and minimal downtime.

2.  Outstanding dustproof and sealing performance (industry benchmark)

In response to the high-dust characteristics of the friction materials industry, Wuxi Xielì has implemented an exceptionally dust-proof design on its mobile units:

Fully enclosed material receiving and discharging:

The material inlet on top of the small vehicle is equipped with an automatic sealing lid or a telescopic flexible connection that opens only when docking with the material hopper and remains completely sealed during movement.

The discharge port is connected to a mixing machine, and when paired with a double-layer sealed skirt, it achieves “zero dust spillage.”

Active negative-pressure vacuum linkage:

The small vehicle comes equipped with or can be connected to a central dust collection interface. At the moments of material loading and unloading, it automatically activates negative-pressure vacuuming to instantly capture any airborne dust, keeping the workshop environment clean and meeting stringent environmental protection and safety supervision requirements.

Key component protection:

Weighing sensors, walking wheels, tracks, and other components all utilize high-grade materials. IP65/IP67 Dust-proof sealing design prevents fine graphite powder or metal powder from entering and causing equipment failure.

3.  High-precision metrology and error-proofing mechanisms

Dynamic Weighing Stability:

Despite being a mobile device, it features a high-precision cantilever beam. / Shear beam sensors combined with shock-absorbing mechanical structures, and PLC The filtering algorithm can quickly stabilize readings after motion ceases, ensuring that the measurement accuracy of trace additives (such as fibers or metal powders) reaches ±. 0.1%~0.5% 。

Smart Error-Proofing System:

RFID/ Barcode Recognition: The vehicle automatically identifies the bin number where it is currently parked. If the program is configured to indicate that this station does not require material addition, the system will lock the discharge valve to prevent accidental operation.

Formula interlock: The system enforces sequential ingredient addition. If the weight of a previous ingredient does not meet the specified standard, the next step is not allowed, effectively preventing human errors such as omissions or over-additions.

4.  Efficient “one vehicle, multiple machines” service capability

Multi-mixer sharing:

A mobile batching vehicle can serve multiple mixers. The system’s scheduling algorithm automatically plans the vehicle’s route: the vehicle in A Immediately after the mixer discharges its contents, proceed to the next hopper. B Batching in the mixer.

This model significantly reduces equipment investment costs (eliminating the need for an expensive weighing system for each mixer) while also improving equipment utilization.

Continuous operation capability:

When multiple vehicles work in coordination, uninterrupted cyclic batching can be achieved, ensuring continuous production without interruption.

5.  Adapt to complex material properties

The raw material forms of friction materials and refractory materials vary dramatically—from fluffy carbon fibers to heavy iron powder, from ultrafine graphite to coarse-grained friction powders. Wuxi Xielie’s mobile systems are highly targeted and tailored to these diverse material types:

Bridge Prevention and Arch Breaking: By coordinating the discharge port of the hopper with the loading port on the trolley, a vibrator, pneumatic rapping device, or mixing arch-breaking mechanism can be integrated to address the issue of fiber materials easily forming bridges.

Anti-static and explosion-proof: For flammable and explosive materials such as aluminum powder and magnesium powder, the entire vehicle is equipped with an anti-static coating and grounding chains. Optionally, it can also be fitted with explosion-proof motors and electrical components, ensuring compliance with... ATEX or domestic explosion-proof standards.

6.  Intelligence and Data Traceability

MES/ERP Seamless integration:

The system software boasts powerful functionality, supporting remote recipe distribution and real-time upload of production data.

The ingredient records for each batch—including time, operator, actual weight, and deviation values—are automatically stored and used to generate quality reports, thereby meeting the stringent quality-tracing requirements of OEMs (such as automotive brake pad suppliers).

Visualized monitoring:

The large screen in the control room can display in real time the location of the carts, their operating status, the liquid levels in the material bins, and alarm information, enabling unmanned or minimally manned operation.

Summary:

Wuxi Xielie’s mobile automatic batching system is particularly well-suited for industries such as friction materials (brake pads), refractory materials, and powder metallurgy—industries that require handling dozens of raw materials, generate significant dust, and frequently switch between different formulations. Thanks to its innovative “mobile weighing” architecture, this system perfectly balances the conflicting demands of high precision, low dust levels, cost-effectiveness, and high flexibility, making it an ideal choice for these industries seeking to upgrade to intelligent manufacturing.
