With the advancement of industrial automation and the continuous improvement of industry requirements for product quality and specifications, as well as the trend of inefficiency of traditional manual filling methods, the emergence of dosage filling machines has dramatically improved the filling speed and overall efficiency of the production line the technology that enables accurate control of product dosage has become an integral part of the modern production process.
1. What is a dosing filling machine?
A dosing filling machine is a filling equipment used to measure and control liquid, powder or granular materials accurately. This filling machine is designed to ensure that each packaging container contains the exact amount and volume of product. The primary purpose of the dosing filling machine is to improve the accuracy, efficiency, and consistency of filling, and it is especially suitable for industries that require strict control of product quantity.
2. Types of dosing filling machines and working principle
Dosing filling machines can adopt different dosing methods according to different needs, the most common of which are the following:
Volume dosing filling machine: Use the volume measurement principle to ensure that the amount of product in each container is consistent by setting the volume of the filler. This applies to liquid or viscous materials.
Gravimetric filling machine: Use a weighing system to measure the weight of materials to control the quantity of product in each packaging container accurately. This is very important for filling requirements that require high precision.
Stacking dosing filling machine: According to the characteristics of the material, the quantity of products in each packaging container is determined by stacking or counting. This is suitable for granular or trim materials.

3. Components of dosing filling machine
The components of a metering and filling machine can vary depending on the specific design and model, but in general, they include the following key components:
- Dosing system: This is the core component of the dosing filling machine and is used to measure and control the quantity filled.
- Flow control device: The flow control device usually includes a filling nozzle and a valve for volumetric filling machines. They are responsible for controlling the material flow and ensuring that the required volume is accurately measured and released during the filling process.
- Weighing System: The weighing system is critical in gravimetric filling machines. It usually includes one or more high-precision load cells installed on a weighing platform to measure the weight of materials.
- Control system: The control system is the intelligent core of the entire dosing filling machine. It can monitor and adjust the filling process to ensure accuracy and consistency. The control system use PLC (programmable logic controller) or other advanced control technology.
- Human Machine Interface (HMI): The HMI is the interface used to interact with the operator, usually a touch screen. Through HMI, operators can set parameters, monitor production processes and perform troubleshooting.
- Structural Frame and Filling Station: This is the support structure of the filling machine and includes the frame that houses the filling spout, weighing platform, and other components.
These components enable metering and filling machines to achieve high-precision, efficient production processes and ensure consistent product quality.
