High-speed Checkweigher

In the large-scale manufacturing industry, high-speed production line operation is the core path for enterprises to boost production capacity and reduce unit costs. However, traditional dynamic checkweighers have long failed to solve the industry's chronic pain point of the inherent trade-off between speed and accuracy. When the line speed exceeds 200 pieces per minute, problems such as a sharp drop in accuracy, frequent false rejection and missed detection are common, resulting in material waste in mild cases, and regulatory penalties for non-compliant net content in severe cases.

With over 20 years of in-depth expertise in the weighing industry, Jiangsu Jutian Weighing Equipment Co., Ltd. (J-SKY), relying on its in-house 919 R&D Center and intelligent manufacturing base in Zhejiang, has developed the J-SKY High-Speed Checkweigher exclusively for high-cycle mass production scenarios. This product completely breaks through the industry's technical bottlenecks, maintaining a dynamic weighing accuracy of ±0.5g even at the maximum detection rate of 300 pieces per minute. It is the core quality control equipment for high-speed production lines to achieve compliant production, cost reduction and efficiency improvement.

J-SKY High-Speed Checkweigher (Models: JDT-CZ-HS30 Belt Type / JDT-GS-HS30 Roller Type) is an industrial-grade dynamic in-line weighing device custom-built for high-cycle, high-volume automated production lines. It can be seamlessly integrated into various assembly lines to perform 100% in-line full weight inspection of products, net content compliance verification, missing component detection, and automatic rejection of non-conforming products, while enabling full traceability of production data.

The product is equipped with an intelligent weighing operating system deeply developed based on the Linux system, paired with an industrial-grade touch interactive interface. It is adaptable to high-speed production scenarios in multiple industries including food and beverage, pharmaceutical, FMCG, hardware and toys, supports full-dimensional customized development, and has been exported to more than 50 countries and regions worldwide.

Core Technical Advantages

Self-developed Dynamic Weighing Algorithm, Achieving Dual Breakthroughs in Speed and Accuracy

Targeting detection error sources in high-speed production lines such as mechanical vibration, product inertia, and airflow interference, the equipment is equipped with J-SKY's self-developed millisecond-level dynamic weight compensation algorithm. It can perform thousands of weight data samplings per second and intelligently filter detection deviations caused by environmental interference. Even at the extreme detection speed of up to 300 pieces per minute, it can stably maintain a dynamic weighing accuracy of ±0.5g, with a grading accuracy rate close to 100%, completely solving the problems of missed detection and false judgment under high-speed production.

Industrial-Grade Hardware Configuration, Ensuring Long-Term Stable Operation

The core of the equipment adopts a high-response industrial-grade weighing sensor, matched with a 24V brushless high-speed drive motor, with a response delay as low as millisecond level. The maintenance-free design of the brushless motor can ensure 7/24 continuous high-speed operation without failure, greatly reducing unplanned downtime losses. The whole machine adopts a 304 food-grade stainless steel frame (316L corrosion-resistant material is optional), is fitted with a standard food-grade PU conveyor belt, and features a modular quick-disassembly structure that can be quickly disassembled and cleaned without tools. It complies with GMP hygiene standards for the food and pharmaceutical industries, while greatly shortening the downtime for production line changeover.

Digital Intelligent System, Adapting to Collaborative Large-Scale Production Lines

The equipment is equipped with a 7/10-inch high-definition industrial touch screen, with a standard Chinese-English bilingual interface. It has a built-in pre-storage function for hundreds of sets of product parameters, which can be retrieved and switched with one click during production changeover without re-debugging, perfectly adapting to the high-speed production needs of multi-category quick changeover. The system can real-time count core data such as total production volume, pass rate, and weight distribution, automatically generate production reports, and support one-click export via U disk. It is reserved with industrial interfaces such as RS232/485 and Ethernet, which can be seamlessly connected to inkjet printers, code scanners, and ERP/MES production management systems to realize full-link digital traceability of production.
