High Precision Automatic Weighing Machine with PLC Touch Screen and Customizable Weighing Range

Our Fully Automatic Weighing Machine is designed for manufacturers who require reliable and continuous weight measurement in modern production environments. The machine integrates a high-precision load cell, intelligent PLC control system, conveyor system, touchscreen HMI and automatic product inspection technology into one compact solution.

During operation, products are automatically transported through the weighing section. The system measures the actual product weight and compares it with the preset target value. Products outside the specified weight range can be automatically identified and rejected.

With flexible weighing ranges, adjustable conveyor speeds and multiple rejector options, the machine can be configured for different products and production-line requirements.

• High-precision dynamic weighing
• Fully automatic operation
• PLC-based control system
• Fast and stable production-line operation
• Automatic overweight and underweight detection
• Multiple automatic rejection options
• Stainless steel machine construction
• Touchscreen HMI operation
• Easy integration with existing production lines
• OEM and ODM customization available

The machine uses industrial-grade weighing sensors and digital signal processing technology to provide stable and repeatable weight measurement during continuous operation. It is suitable for applications where consistent product weight and automatic inspection are important.

• Stable weighing performance
• High repeatability
• Fast measurement
• Automatic weight comparison
• Reduced manual inspection

The weighing accuracy can be configured according to product weight, production speed and application requirements.

The automatic weighing machine can be installed directly into continuous conveyor-based production and packaging lines. Products are automatically transferred through the weighing section without requiring manual weighing.

Maximum conveyor speed: Up to 60 m/min
Processing capacity: Up to 120 pcs/min

Actual production speed depends on product dimensions, weight, spacing and production-line configuration.

The PLC control system provides reliable machine operation and allows different production parameters to be configured according to product requirements. The optional color touchscreen HMI provides a simple interface for operators.

• Product parameter setting
• Target weight setting
• Weight monitoring
• Production data management
• Product program switching
• Alarm monitoring
• Machine status display

Multiple product programs can be stored for faster product changeover.

The system continuously compares the measured product weight with preset upper and lower limits. Products can be automatically classified as underweight, qualified, or overweight.

When an out-of-specification product is detected, the system can activate an alarm and automatically remove the product from the production flow. This helps reduce human inspection errors and improve overall production consistency.

Different rejection mechanisms can be configured according to product type and production-line requirements.

Air-Blast Rejector
Suitable for lightweight products and high-speed applications.

Pusher Rejector
Suitable for boxed, bagged and relatively stable products.

Drop-Down Rejector
Suitable for specific conveyor layouts and heavier products.

The rejection system can be customized according to product size, weight, shape and required production speed.

The touchscreen control interface allows operators to quickly adjust production parameters. The system can store preset parameters for different products, making product changeover easier and reducing setup time.

Operators can monitor current weight, target weight, upper/lower limits, production quantity, machine status, and alarm information.

For modern automated factories, the weighing machine can be equipped with multiple communication interfaces.

• USB
• RS232
• RS485
• Ethernet

The system can be configured to communicate with compatible production management, data collection or factory automation systems.

Technical specifications can be customized according to product characteristics and production-line requirements.

Every production line has different requirements. We provide customized automatic weighing solutions based on product characteristics, production capacity and factory layout.

The weighing range can be configured according to product weight, package weight, product dimensions, required accuracy, and production capacity.

Standard weighing range: 10–5000 g

The weighing system can be optimized according to the required balance between accuracy and production speed. Our engineers can configure the system based on target accuracy, product weight, conveyor speed, product spacing, and required production capacity.

Choose from different automatic rejection solutions: air-blast, pneumatic pusher, drop-down, or customized rejection mechanism. The appropriate solution is selected according to product size, weight, shape and conveyor configuration.

Optional HMI configurations include 7-inch touchscreen, 10-inch touchscreen, multi-language interface, product recipe management, production data display, and customized operation interface.

The machine can be supplied according to the electrical standards of the destination market. Available configurations include AC 220V, AC 380V, 50Hz / 60Hz, and customized electrical components.

Suitable for automatic weight inspection of packaged food, snacks, bakery products, canned food, bottled products, food containers, and pre-packed products. The system helps identify products that do not meet the specified weight requirements before final packaging or shipment.

Suitable for chemical packages, powder products, granular materials, industrial raw materials, and chemical containers. Different conveyor and weighing configurations can be selected according to material characteristics.

The machine can be used for automatic weight verification of hardware, small components, industrial parts, mechanical accessories, and packaged components. Weight checking can also help identify missing components in packaged products.

The weighing machine can be integrated into filling lines, packaging lines, inspection lines, sorting lines, assembly lines, and automatic production lines. It provides an additional quality-control step before finished products are packed and shipped.

For high-volume parcel handling, automatic weighing can be used for parcel weight verification, shipping inspection, package sorting, weight-based classification, and order checking.

To ensure reliable machine performance, each automatic weighing system can be inspected and tested before shipment.

We first confirm product type, product weight, package dimensions, required accuracy, production speed, conveyor layout, and reject requirements.

The main mechanical components are assembled, including machine frame, conveyor, weighing platform, load cell, protective components, and automatic reject mechanism.

The electrical control system is configured according to the machine specifications. Main procedures include PLC programming, sensor connection, HMI configuration, alarm setting, rejector configuration, and safety system testing.

The weighing system is calibrated before delivery. Testing may include zero calibration, standard-weight calibration, repeatability testing, target-weight setting, and weight deviation testing.

Before shipment, the machine is tested under operating conditions. Inspection items include weighing accuracy, conveyor stability, sensor response, PLC operation, touchscreen operation, alarm response, automatic rejection, emergency stop, and safety protection.

The machine is carefully prepared for international transportation. Standard protection can include stretch film, moisture protection, component protection, machine fixing, reinforced export packaging, and wooden case packaging when required.

We can support sea freight, container shipping, international logistics, door-to-port transportation, and equipment combined shipment. Packaging and transportation solutions can be discussed according to destination country and shipping method.
