All-stainless Steel Non-powered Intelligent Roller Conveyor Scales

The All-stainless Steel Non-powered Intelligent Roller Conveyor Scales are static weighing platform manufactured by Jiangsu Jutian Weighing Equipment Co., Ltd. It is designed for workstations where goods must be weighed during manual or gravity-fed transfer—such as receiving docks, pre-shipment inspection points, production line material stations, and warehouse inventory zones. The equipment combines a 304 stainless steel roller deck, a structurally integrated load cell assembly, and a digital weighing indicator within a single unit.

Goods are placed onto the roller surface manually or via an adjacent conveyor section. The rollers allow the item to be positioned or moved across the weighing platform without lifting. The load cells measure the static weight once the item is at rest, and the indicator displays, records, or transmits the reading. No external motor drive is used for the roller mechanism, eliminating the need for drive belts, motor controllers, and associated electrical components at the weighing station.

Technical Specifications (Configurable)

Configuration notes: Weighing capacity, platform dimensions, roller diameter, and roller spacing are specified during ordering to match the intended product size range and workflow. Division value is matched to the selected capacity to provide appropriate measurement resolution for the application.

Jiangsu Jutian Weighing Equipment Co., Ltd. operates under ISO9001-certified quality management, with CE certification for its products. The company holds 68 national patents and 20 software copyrights developed through its 919 R&D Center. Production is conducted across two manufacturing facilities with standardized quality control procedures covering material inspection, welding and assembly, load cell calibration, and final functional testing.

Material Selection and Structural Design

The All-stainless Steel Non-powered Intelligent Roller Conveyor Scales frame and roller assemblies are constructed from stainless steel 304. This material selection addresses several operational requirements common in industrial weighing environments. Stainless steel 304 provides inherent corrosion resistance, making the equipment suitable for facilities where the scale may be exposed to moisture, cleaning agents, or mildly corrosive atmospheres—such as food processing plants, pharmaceutical production areas, chemical warehouses, and cold storage facilities.

The fully enclosed structural design prevents dust, debris, and liquid ingress into the load cell compartment. The load cells are positioned beneath the roller deck in a mechanically protected configuration. Welded joints on the frame are continuous and ground smooth to eliminate crevices where contaminants could accumulate, supporting hygiene requirements in regulated industries.

The roller deck is designed to support goods of varying base rigidity. The roller diameter and spacing can be configured to accommodate the minimum package or pallet footprint in the application. For products with uneven bases or flexible packaging, closer roller spacing provides more uniform support and reduces measurement variation caused by load distribution.

Gravity-Fed Operation and Low-Maintenance Design

The non-powered roller mechanism relies on gravity or manual force to move goods across the weighing platform. When the roller deck is installed with a slight incline or when goods are pushed manually, the rollers rotate freely on sealed bearings, allowing items to glide into position for weighing and exit after measurement. This design eliminates the need for drive motors, belts, chains, or motor controllers at the weighing station.

The absence of powered drive components reduces several operational considerations. Energy consumption at the weighing station is limited to the digital indicator. Routine maintenance is confined to periodic roller bearing inspection, platform cleaning, and calibration verification. There are no drive belts to tension or replace, no motor brushes to wear, and no electrical components in the roller assembly to protect from washdown or dust exposure.

Indicator Functions and Communication

The color touchscreen indicator provides standard weighing functions including zero-setting, taring, unit conversion (kg/g/lb), and weight accumulation. The built-in alarm function supports configurable upper and lower weight limits, with visual and audible alerts triggered when a measured weight falls outside the acceptable range. This checkweighing mode allows the scale to serve as a manual quality control station without additional equipment.

Data storage capacity of 10,000 or more records supports batch traceability and inventory reconciliation. Stored records can be exported via USB in CSV format for analysis or documentation. Optional communication interfaces (RS232, Wi-Fi, Ethernet) enable real-time data transmission to a connected PC, PLC, or host system. Protocol configuration is handled during system setup to match the receiving platform.

FAQ (Frequently Asked Questions)

Why choose stainless steel 304 over carbon steel for the scale frame?
Stainless steel 304 provides corrosion resistance without the need for paint or coating that can chip or degrade over time. In food processing, pharmaceutical, chemical, or high-humidity environments, carbon steel with painted finish may develop rust at scratches or weld points. Stainless steel 304 is compatible with standard cleaning and sanitizing procedures used in regulated industries.

How does the roller mechanism function without a motor?
The rollers are mounted on sealed bearings and rotate freely. Goods are moved across the platform by manual pushing or by installing the scale with a slight incline so that gravity advances the items. This design is suited to manual workstations, the end of a powered conveyor line where momentum carries items onto the scale, or auxiliary inspection points where powered conveying is not required.

How is accuracy affected when weighing items that are not rigidly flat?
Items with uneven or flexible bases should be supported across multiple rollers. The roller spacing can be reduced during configuration to provide more uniform support. For products such as bulk bags, drums, or palletized loads with rigid bases, standard roller spacing is typically sufficient. The load cell assembly is designed to sum the total load regardless of its distribution across the platform.

Can the scale be integrated with an existing warehouse management system?
Yes. Optional communication interfaces—including RS232, USB, Wi-Fi, and Ethernet—support data output to connected systems. Weight data, timestamps, and transaction records can be transmitted in real time or exported in batch. The specific data format and communication protocol are configured during setup to match the host system requirements.

What maintenance is required for the non-powered roller system?
Periodic inspection of roller bearings for free rotation, cleaning of the roller surface and scale platform, and calibration verification with certified test weights constitute the primary maintenance tasks. The sealed bearing design does not require regular lubrication under normal operating conditions. The stainless steel surface can be cleaned with standard industrial cleaning agents compatible with stainless steel.
