Wuxi Xielie’s Mobile Weighing and Batching Automation System Mobile Weighing & Batching Automation System ) is an innovative industrial ingredient solution.

Its core concept is: “Get the scale moving to find the material,” rather than the traditional approach of “letting the material flow down onto a fixed scale.”

I. What is a mobile weighing and batching system?

1.  Basic definition

This is a mobile device—such as a batching cart—that integrates a high-precision weighing module, a feeding and receiving unit, a control system, and a walking mechanism. AGV Automated Guided Vehicle or RGV The system on the tram.

Working method: The mobile vehicle travels along a track (or magnetic strip). / (Laser navigation path) automatically moves beneath neatly arranged raw material bins.

Operation procedure:

1.1 The small vehicle moves under the designated hopper.

1.2 The sealing mechanism automatically docks, and the hopper valve is opened, allowing the material to fall into the weighing hopper integrated into the cart.

1.3 After reaching the set weight, close the valve.

1.4 The small cart moves to the next station (the next hopper or mixer) and repeats the above process until all ingredients have been assembled.

1.5 Finally, unload the prepared materials into a mixer or container.

2.  Core architecture

Mobile carrier: typically an explosion-proof electric trolley (with tracks) RGV ) or autonomous navigation vehicles (trackless) AGV ).

Weighing unit: High-sensitivity sensor +  Damping structure ensures rapid stabilization of readings once movement stops.

Sealed interface: A unique telescopic chute, inflatable sealing ring, or double-flap valve ensures dust-free material transfer during movement.

Intelligent Scheduling: Central Control Software ( WCS/MES ), plan the optimal route, prevent multi-vehicle collisions, and manage the order of formulations.

II. Main Uses and Application Scenarios

The mobile weighing system primarily addresses the production challenges posed by a wide variety of raw materials, limited space, high dust levels, and frequent formula changes.

1.  Core application areas

Friction Materials Industry (Brake Pads) / Clutch disc):

Scene: Mixing graphite, metal powder, fibers, resin, and other materials is required. 30-60 Different raw materials.

Application: A small vehicle shuttles between dozens of hoppers, sequentially weighing tiny amounts of additives and large quantities of base materials before directly discharging them into a mixer. This is the system’s most typical application (e.g., the solution adopted by companies such as Wuxi Xielì).

Refractory Materials and Ceramics Industry:

Scene: A wide variety of raw materials (various mineral powders and additives) are present, and dust levels are extremely high.

Application: Achieves fully enclosed ingredient preparation, preventing dust from contaminating the workshop while accommodating a production model featuring multiple varieties in small batches.

Feed and Food Industry:

Scenario: Ingredients need to be supplied to multiple production lines, but the factory space is limited.

Application: A single mobile unit serves multiple mixers, reducing equipment investment and making cleaning easier to prevent cross-contamination.

Chemical Engineering and Plastic Modification:

Scene: Involves flammable and explosive powders or toxic chemicals.

Application: By using a fully enclosed, mobile weighing system, operators are completely isolated from hazardous materials, and the explosion-proof design ensures safety.

Battery materials (lithium-ion cathode and anode):

Scenario: Extremely high requirements for metallic foreign objects and cleanliness.

Usage: The mobile system can reduce residue in fixed pipelines, making thorough cleaning easier and preventing cross-contamination between different batches.

2.  Specific pain points addressed (detailed use cases)

Intensive layout: Just one rail and a few small carts are needed under dozens of large hoppers, saving... 50% The above space.

Shared resources: N A small car can provide service. M Tai Mixer ( M>N ), significantly reducing the costs of weighing equipment and steel structures.

Source sealing: The connection between the trolley and the hopper, as well as between the trolley and the mixer, are all... “ Point-to-point ” Hard sealing or soft connection—almost zero leakage.

Independent containers: Each vehicle load is weighed independently, and after unloading, the containers can be automatically purged or cleaned. This makes them ideal for multi-variety, small-batch production.

Flexible expansion: Simply extend the track and add new hoppers—no major overhaul required, just a software update.

III. Example of System Workflow

Suppose a brake pad factory needs to produce a batch of products, and the formulation includes: 40 Raw materials:

1. Task Assignment: The operator selects a recipe in the control room, and the system automatically generates a task queue.

2. Automatic addressing: The empty material-handling cart departs and, guided by an algorithm, plans its route to the first destination. 1 Below the feeding hopper (such as graphite).

3. Precise material pickup: The roof sealing cover rises and fits snugly against the hopper opening. ->  Open the valve ->  Roughly add / Fine addition ->  Meet the weight requirement. ->  Close the valve.

4. Cyclic operation: The trolley moves toward No. 2 Number, No. 3 Number ... Until the ... 40 The batching bin sequentially completes the cumulative weighing of all raw materials.

5. Discharge and Mixing: The fully loaded cart travels to above the designated mixer, aligns itself with the feed inlet, opens the bottom valve, and discharges all the raw materials at once or in sequence.

6. Self-cleaning / Reset: After unloading is complete, the cart may pass through an automatic cleaning station to remove any remaining residue, then return to the standby area or proceed to the next task.

IV. Summary

The mobile weighing and batching automation system is essentially an embodiment of “flexible manufacturing” in the batching process.

What it is: an automated robotic system that can run and is equipped with a high-precision scale.

Core value: Achieve more complex (multi-component) batching tasks with fewer devices (shared scales), smaller spaces (dense storage), and a better environment (fully enclosed).

Best Partner: Particularly well-suited for industries with a wide variety of raw materials—such as friction materials, refractory materials, and specialty chemicals—where dust levels are high and there’s a strong demand for flexible formulations.
