300 bottles/h Big Capacity Bucket Weighing Packaging Machine

Weighing Packaging Machine Product Introduction 

The 300 bottles/h big capacity bucket weighing packaging machine is designed for precise filling of large-volume liquid or semi-liquid products, widely used in chemical, food, lubricant, and daily chemical industries. Equipped with high-precision load cells and a PLC control system, it synchronizes weighing and filling to ensure consistent output. It supports various bucket sizes and includes functions such as automatic tare, error correction, and data monitoring. Built with corrosion-resistant materials, it ensures long-term continuous operation and integrates easily with conveyors, capping, and labeling systems for a complete automated line.

Working Principle：

Empty buckets enter the weighing platform and are automatically tared. The system opens the filling valve based on the preset weight, allowing material to flow into the bucket. As the target weight is approached, the filling speed slows down and stops precisely at the set value. The PLC monitors weight changes in real time and adjusts for errors, ensuring accurate and consistent filling before transferring to the next process.

Main features：

• High-precision dynamic weighing system – advanced load cells with real-time feedback ensure stable accuracy even under continuous high-load operation.
• Dual-stage filling control – fast filling + slow topping near target weight, effectively improving accuracy while maintaining high efficiency.
• Automatic tare & intelligent compensation – eliminates container weight variation and adjusts for material density changes.
• Wide weighing range compatibility – suitable for small to large buckets and drums with flexible parameter settings.
• Corrosion-resistant wetted parts – optional SS304/SS316 or anti-corrosion materials for chemical and aggressive liquids.
• Anti-drip filling valve design – prevents dripping, foaming, and product loss, ensuring clean filling environment.

Application Scenarios：

• Chemical industry – filling acids, alkalis, solvents, detergents, and industrial liquids.
• Lubricant & oil sector – packaging engine oil, hydraulic oil, gear oil, and industrial lubricants.
• Food industry – filling edible oil, sauces, syrups, and other liquid or semi-liquid products (with food-grade configuration).
• Daily chemical products – packaging cleaning agents, disinfectants, liquid soap, and detergents.
• Paint & coating industry – handling viscous liquids such as coatings, resins, and adhesives.
• Bulk liquid packaging – suitable for medium to large container filling in logistics and distribution centers.
