Product positioning
This product is a high-capacity dynamic checkweigher specifically designed for online weighing and sorting of heavy, bulky items. Unlike high-speed, precision checkweighing equipment, its core advantages lie in its robustness, operational stability, and versatility. It can reliably perform dynamic weight measurement, data feedback, and pass/fail judgment on materials weighing up to 100 kg—even under harsh industrial conditions—such as bulk bagged goods, boxed raw materials, and industrial components. It seamlessly integrates with medium- and low-speed heavy-duty production lines.
Core Design and Technical Highlights
Super-strong structure, worry-free under heavy loads:
The entire instrument is welded from SUS304 stainless steel with a thickness exceeding 3 mm, featuring a rigid structure that is highly resistant to deformation and corrosion. It is specially designed to withstand prolonged impact loads of up to 100 kg, ensuring that the weighing platform remains stable even under heavy loads and maintaining long-term accuracy.
Stable weighing, highly adaptable:
Given the high inertia of heavy objects, a design philosophy emphasizing low speed and high stability has been adopted. The adjustable slow-speed conveyor (2–10 meters per minute) ensures that heavy objects pass smoothly through the weighing section, providing the sensor with a stable sampling period and thereby achieving reliable ±10g accuracy over a wide measurement range.
Wide-temperature operating design (-10℃ to 40℃) allows it to adapt to various industrial environments such as warehouses and workshops.
Human-centered and highly visible interaction:
A 10-inch large-size color touchscreen with an intuitive interface allows clear visibility of weight, results, counts, and other information even from a slightly farther distance. Additionally, a protective guard is included to effectively prevent damage from accidental collisions.
The three-color alarm light plus buzzer provides a striking audio-visual alert: a green light indicates “pass,” a yellow light indicates “underweight,” a red light indicates “overweight,” and an error alarm is also provided, making the production line status instantly clear at a glance.Flexible integration and installation:
The production line height (450–480 mm) is compatible with common conveyor systems. The adjustable foot bolts allow for fine-tuning of up to ±50 mm, easily addressing issues caused by uneven floors or differences in docking heights.
Standard I/O interface allows for easy connection to scanners, printers, or PLC systems, enabling weight data binding and process control.Typical workflow
Load heavy items → Gently enter the reinforced weighing section at a low speed (e.g., 5 meters per minute) → High-rigidity sensors acquire stable weight signals → The control system processes the data and displays it on the touch screen → The system compares the measured weight with preset upper and lower limits → Triggers the corresponding three-color alarm lights (Pass/Underweight/Overweight) → Data can be output for subsequent sorting or recording → The item slowly exits, preparing for the next cycle.
Core application scenarios
This product is suitable for various industrial sectors that require online weight inspection of heavy-weight packaging or products:
Chemicals and Building Materials: Verification of the net weight of bagged products weighing 25-50 kg, including fertilizers, feed, putty powder, mortar, and similar items.
Grain and Food Processing: Bagged weight inspection of bulk food ingredients such as rice, flour, and white sugar.
Logistics and Warehousing: Freight Calculation and Weight Tiering for Heavy E-commerce Parcels and Standard Containerized Goods.
Manufacturing: Weight sorting and missing-part inspection for mass-produced heavy-duty components, motors, and metal castings.
Waste Recycling: Weighing and metering of packaged renewable resource bundles.
The core value created for the customer
Reliability First: Optimized for heavy-duty applications, featuring a robust structure, stable speed, low failure rate, and ensuring continuous production.
Eliminate cost vulnerabilities: Implement 100% online weight inspection to avoid trade disputes or customer complaints caused by insufficient filling volumes, and also prevent raw material losses resulting from overfilling.
Enhance job standardization: Replace manual lifting and weighing—prone to errors, inefficient, and posing risks of work-related injuries—with automated inspection and weighing of heavy objects.
Clear process management: Intuitive audio-visual alarms and touchscreen data make production status and quality results visible in real time, facilitating easy management.
Strong environmental adaptability: The thick stainless steel body is corrosion-resistant and easy to clean. Its wide-temperature design makes it suitable for a variety of industrial environments.
Summary: This 100 kg high-capacity dynamic checkweigher is a heavy-duty industrial weighing solution centered on robustness, stability, and reliability. Rather than pursuing extreme speeds, it focuses on providing durable, accurate, and efficient weight-checking services under heavy-load, medium-to-low-speed operating conditions. It serves as a reliable partner for the chemical, building materials, grain, and heavy manufacturing industries in achieving automated checkweighing and quality control.
