In today’s fast-evolving intelligent weighing and packaging industry, a high-precision, high-stability multihead weigher has become the core requirement for automated packaging lines across every sector. Founded in 2007, LEESOLU has grown into a benchmark high-tech enterprise in China’s intelligent weighing and packaging machinery sector through nearly two decades of industry dedication. The company specializes in the R&D, production and sales of core metering equipment — including multihead weighers, linear weighers and automated weighing & packaging integrated systems — and has built a solid industry reputation and core competitiveness through strong technical accumulation and standardized production systems.
Continuous technological innovation is the foundation of LEESOLU’s market position. The company has long invested in R&D and intellectual property, holding multiple independently developed IP rights covering invention patents, utility model patents, design patents and software copyrights.
Backed by a complete R&D and production system, LEESOLU offers a full-range product matrix of intelligent packaging equipment, including multihead combination weighers, linear weighers, weight inspection machines, various automatic packaging machines, foreign object detection equipment and parallel robots. Among them, the independently developed 14-head high-precision combination weigher is the flagship model engineered for precision weighing and high-accuracy subdivision scenarios. It is precisely suited for quantitative weighing and filling of granular materials such as Chinese herbal slices, tea, crop seeds, chicken essence and condiments, chocolate beans and more. The product is widely applied in snack food, pet food, frozen and ready-to-eat food, fresh-cut vegetables, aquatic and seafood, hardware, agricultural products and other production scenarios, delivering outstanding adaptability and practicality.
Targeting Industry Pain Points
Addressing common industry challenges — weighing deviation for granular materials, material clogging, and difficult fault diagnosis — LEESOLU’s 14-head high-precision combination weigher has undergone comprehensive functional optimization:
High-precision digital sensing components improve sampling accuracy at the hardware level.
Combined weighing & counting dual function improves counting accuracy.
Mechanical Structure Design
Focused on the demands of high-precision continuous production, this model features dedicated structural optimization:
Ultra-low-vibration main vibration system ensures stable operation and uniform material distribution, eliminating weighing deviation caused by body vibration at the source.
Customized V-shaped vibration pan precisely controls the discharge speed and volume of low-weight materials, guaranteeing uniform and stable feeding.
Frame-type chassis structure reinforces overall rigidity and structural stability, effectively shortening hopper stabilization time and markedly improving the production tempo and efficiency of the entire line.
Comprehensive Pre-Sales & After-Sales Service
To fully safeguard customers’ production, LEESOLU has established a one-stop, highly responsive pre-sales and after-sales service system with professional teams for technical consultation, hands-on training and equipment maintenance. Beyond standard industry service levels, the company provides warranty coverage for all equipment and operates a 24-hour rapid-response after-sales mechanism, quickly addressing equipment commissioning, fault repair, technical consultation and other needs — ensuring stable commissioning and long-term operation, and protecting every customer’s production.
Frequently Asked Questions
Q: What materials and production scenarios is the LEESOLU 14-head combination weigher suitable for?
A: This model is precisely positioned for precision weighing and high-accuracy scenarios. It is ideally suited for granular materials including Chinese herbal slices, tea, seeds, chicken essence, nuts, chocolate beans, vegetable salad and hardware parts, and is widely used in refined quantitative filling across the snack food, agricultural product, pharmaceutical and hardware industries.
Q: How does the equipment ensure weighing accuracy during continuous production of small-granule materials?
A: Weighing accuracy is guaranteed through three synergistic dimensions: hardware configuration, intelligent algorithms and mechanical structure. High-precision digital sensors ensure fundamental sampling accuracy; the optimized proprietary sampling algorithm combined with dynamic zero-point tracking technology calibrates runtime errors in real time; and the combined structure of ultra-low-vibration main vibration, customized V-shaped pan and side-drive weighing module achieves uniform material feeding and stable equipment operation, continuously maintaining high-precision weighing under continuous production conditions.
Q: Does the manufacturer provide installation, commissioning and operator training after purchase?
A: LEESOLU is equipped with a professional technical service team that provides full technical support, including equipment installation and commissioning, operator hands-on training and daily maintenance guidance — helping customers bring equipment into production quickly and master operation skills efficiently.
Q: How stable is the 14-head combination weigher during long-term operation? Will accuracy drift occur?
A: The equipment adopts a high-rigidity frame-type (“口”-shaped) chassis structure with strong stability and anti-interference capability, paired with a high-stability weighing module and dynamic zero-point tracking technology. Under standardized daily maintenance, the equipment maintains a stable weighing state over the long term, is not prone to accuracy deviation, effectively reduces calibration frequency and lowers enterprise maintenance costs.
Q: Can LEESOLU provide customized solutions for a customer’s existing production line?
A: The company possesses full R&D and implementation capability for automated weighing and packaging integrated systems. Based on the customer’s existing production line configuration, operating conditions and material characteristics, we can customize dedicated equipment solutions to achieve efficient adaptation and seamless integration with existing lines, optimizing overall production efficiency.
