Weight Re-Inspection Machine

Jiangsu Jutian J-SKY is a professional manufacturer of weight re-inspection equipment in China with over 20 years of deep experience in the weighing industry. Equipped with an independent 919 R&D center and intelligent production base, we provide full-process weight control solutions tailored for factory assembly lines.

Our newly launched JDT-RC-A20 Weight Re-Inspection Machine is a dedicated end-of-line weight rechecking system for packaging lines. It is mainly used for online weight re-inspection of products on production lines, accurately judging whether product weight meets standards, identifying missing parts, incomplete assembly, and net content deviations. It fundamentally intercepts non-conforming products before they leave the factory, greatly reducing customer complaints and compliance risks.The machine supports full non-standard customization and bulk orders, with standard models in stock for fast delivery.

Why Your Production Line Must Be Equipped with a Weight Re-Inspection Machine?

As global regulations on prepackaged products become stricter and end customers demand higher product quality, end-of-line weight re-inspection is no longer optional—it has become a necessity for manufacturers to maintain quality control, avoid compliance risks, and protect brand reputation.

This Weight Re-Inspection Machine is designed to solve four core industry pain points:

1. Compliance Risk Control

Precisely controls net content deviations to meet global regulatory requirements such as the Measures for the Supervision and Administration of Metrology of Prepackaged Goods, avoiding heavy losses from regulatory penalties and product recalls caused by non-compliant net content.

2. Customer Complaint Interception

100% full inspection replaces manual sampling, thoroughly detecting missing parts, incomplete filling, and underfilling. It prevents defective products from reaching the market, fundamentally reducing complaints and safeguarding brand reputation.

3. Cost Reduction & Efficiency Improvement

Capable of 24/7 uninterrupted operation, one machine replaces 2–3 full-time quality inspectors, significantly lowering labor costs and intensity.Detection speed reaches up to 120 pieces per minute, fully matching medium-to-high speed line tempo without becoming a bottleneck.

4. Digital Production Traceability

Complete weighing records for every product, supporting data storage, query, export, and system integration.Solves management problems such as error-prone manual records, lack of traceability, and inability to locate quality root causes, helping factories achieve digital production management.

Dual-Type Selection Matrix – 100% Adaptable to Your Products & Line

We offer roller type and belt type versions, flexible for different product sizes, materials, and line layouts. Full customization is available, enabling seamless integration without modifying existing lines. It works perfectly with upstream packaging machines, metal detectors, and downstream inkjet printers, labeling machines, and sorters.

Five Core Technical Advantages – Ensuring Recheck Accuracy & Long-Term Stability

1. Ultra-High Precision Dynamic Weighing – Zero Missed Detection, Zero False Detection

Equipped with industrial high-precision weighing sensors and proprietary dynamic digital filtering algorithms, effectively eliminating interference from line vibration and conveying inertia.

Weighing range: 2g ~ 10kg

Detection accuracy: up to ±0.1g

Max speed: 120 pieces per minute

Accurately captures tiny weight differences such as single tablets or small parts, completely preventing underfilled or incomplete products from passing through.

2. Full-Link Line Interconnection – Automated Quality Control Closed Loop

Standard industrial communication ports: RS232/485, Ethernet, enabling deep integration with upstream and downstream equipment:

Upstream: Real-time weight data feedback to packaging/filling machines; automatic parameter adjustment for consistent batch weight.

Downstream: Pass/reject signals to printers, labelers, sorters for fully automatic “re-inspection → labeling → rejection” workflow.

Management: Connects to factory MES/ERP systems for real-time data upload, full traceability, and support for production optimization, cost accounting, and compliance audits.

3. Intelligent Data Management – Full Process Traceability

7-inch industrial HD touch screen with Chinese/English bilingual interface, easy to operate without professional training.

Stores hundreds of product recipes for one-click recall during changeovers.

Real-time statistics of output, pass rate, defect types.

Weighing records exportable via USB in Excel/PDF for permanent archiving.

Hierarchical authority management prevents unauthorized parameter changes, ensuring data security and accuracy.

4. Food-Grade Industrial Design – For Harsh Environments

Main body made of food-grade 304 stainless steel, optional 316L corrosion-resistant stainless steel for food, pharmaceutical, and chemical industries.Modular quick-release structure with no hygienic dead corners, easy to disassemble and clean, fully compliant with GMP standards.Standard IP54 protection, stable in humid, dusty workshop environments.

5. Flexible Rejection Solutions – Precise Interception of Defects

Supports two mainstream rejection methods:

Pusher type: for heavy, hard-packaged products

Air-blast type: for thin, soft-packaged products

Millisecond-level response with photoelectric confirmation sensors ensures 100% interception rate—no false rejects, no missed rejects, and no damage to packaging.

Modular System Structure

The machine adopts an integrated four-module design, ensuring stable operation, easy maintenance, troubleshooting, and function upgrades.

Conveying Buffer Section

Smoothly receives upstream materials, matches speed to eliminate inertia, ensuring stable entry into the weighing zone.

High-Precision Weighing Section

Core detection unit with industrial load cells, high-precision platform, and dynamic acquisition system for accurate weight reading within milliseconds.

Automatic Rejection Section

Executes precise rejection based on weighing results, with reject collection channel and photoelectric sensor. Alerts and stops on jams to prevent non-conforming products from passing downstream.

Intelligent Control Cabinet

The “brain” of the machine, integrating control system, touch screen, data storage, and communication modules. Supports software customization and system upgrades.
