A three-head weighing filling machine is automatic packaging equipment that completes material filling based on weighing measurement. With multiple weighing units working together, it is mainly used for quantitative filling of granular and small solid materials into cans, buckets, stand-up pouches, cartons and other containers. It is widely used in snack food, grain, dried goods and hardware accessory industries. Different from volumetric filling, it takes real-time weight as the measurement standard and is less affected by variations in material bulk density.
The machine consists of weighing hoppers, feeding mechanisms, a control system and a frame. The three weighing channels operate independently while coordinating with one another. Materials are fed into hoppers, weight sensors collect data, and the system stops feeding once the target weight is reached before discharging materials into packages. Product contact parts are usually made of stainless steel for easy disassembly and cleaning, complying with hygiene requirements for food production and reducing residue risks during product changeovers.
This machine suits continuous packaging work. Compared with single-head weighing equipment, the multi-channel design supports a smoother material feeding rhythm and stable production flow. It can run as a standalone unit or connect with conveying, sealing and labeling machines to form a complete packaging line.
Routine maintenance focuses on cleaning and inspecting hoppers, feeding gates and weighing sensors to prevent dust and debris from interfering with weight detection. When selecting the machine, buyers should consider material shape, target filling weight range, container style and workshop conditions. Proper selection maintains stable weighing and feeding performance to meet the quantitative packaging requirements for solid materials.
