Weight Packing Machine——High-Precision Bulk Weighing and Packing System
At MIC Machinery, we specialize in advanced Weight Packing Machines designed for precise and efficient handling of powders, granules, and bulk materials. These machines are engineered to meet the demanding standards of modern chemical, food, and pharmaceutical production environments, where accuracy, speed, and reliability are critical.
Working Process
The Weight Packing Machine for liquid and viscous products operates through a precise workflow designed to ensure accurate volumetric filling, minimize waste, and maintain production efficiency:
➀ Material Feeding: Liquid or semi-liquid products are delivered from storage tanks or mixing vessels to the machine hopper via pumps or gravity-fed pipelines. For high-viscosity liquids, heated transfer lines or positive displacement pumps can be used to maintain flow.
➁ Weighing / Dosing: Load cells or flow meters measure the exact weight or volume of liquid to be filled. The system can operate in incremental or continuous dosing mode, providing accurate and repeatable fills for each container.
➂ Container Positioning: Drums, barrels, jerrycans, or bottles are automatically aligned under the filling nozzle using conveyor systems and positioning guides.
➃ Filling: The measured liquid is dispensed into the container. For foamy or high-viscosity liquids, multi-stage filling or vacuum-assisted nozzles prevent spillage and air entrapment. The system can handle a wide range of liquid types, from lubricants and syrups to liquid soaps and agrochemicals.
➄ Sealing and Discharge: After filling, containers can be capped, sealed, or plugged automatically. The finished containers are then discharged onto conveyors or pallets for further processing, labeling, or storage.
