Fully automatic weigh-filling line for 1 to 7 liters, for all types of oil

The fully automatic weigh-filling line is an integrated line that fills products with high accuracy based on weight measurement. It is widely used in industries that demand a high level of filling accuracy, such as food, chemicals and pharmaceuticals.

This automatic weigh-type engine oil filling and packing machine fills liquids precisely using high-accuracy weight sensors, giving a consistent volume that is not affected by changes in viscosity or temperature. It supports a filling range of 1 to 7 liters and reaches 800–1,200 four-liter containers per hour. No parts need to be swapped, and containers of different shapes and specifications can be adjusted and changed over quickly, so the machine adapts well to varied applications.

The machine has an anti-drip, anti-leak design and an independent weighing unit on every nozzle. The frame and all product-contact parts are made of stainless steel, which makes washing and maintenance easy. It is designed to be simple to install, commission and use, and needs no lengthy operator training. It is fitted with an HMI operator interface and is easy for the operator to run.

How the filling machine works: an automatic cycle of feeding, weighing, filling and discharge, with no manual intervention.

1. Container positioning: the conveyor brings empty containers to the filling station and a clamp fixes their position. The required weight can be adjusted quickly for different containers (1–7 liters), in a simple, user-friendly system.

2. Weighing and filling: while the product is being discharged from the nozzle, the weighing system feeds back weight data in real time. As the target weight is approached, filling slows and finishes gradually. Once the set weight is reached, the valve closes.

3. Data logging: the machine can store filling parameters (such as weight and speed) for different products and supports quick switching between recipes.
