Detailed explanation of the process principle of large capacity liquid filling machine
Date: 2025-06-20Read: 34
The core process principle of a large capacity liquid filling machine (usually referring to the filling of 10-50 liter containers) is based on the coordinated operation of precise metering, efficient conveying, and intelligent control technology. The main processes and technical points are as follows:
1、 Precision measurement system
1. Weighing and filling technology
Real time monitoring of liquid quality through high-precision weighing sensors, combined with PID closed-loop control system to dynamically adjust flow rate, avoiding interference from temperature and bubbles on volume measurement, with an accuracy of ± 0.1% (such as 25L barrel filling).
2. Volumetric measurement
Using servo motors to drive plunger pumps or flow meters (such as electromagnetic flow meters), combined with temperature compensation algorithms to adjust density changes, with a resolution of 0.01ml.
2、 Fluid Control and Pollution Prevention Design
1. Closed flow channel
The liquid cylinder to the filling valve adopts a sealed pipeline to reduce oxygen contact (oxidation prevention) and external pollution.
2. Negative pressure defoaming and drip prevention
Start vacuum suction immediately after filling to eliminate wall droplets;
Damping filling nozzle reduces liquid impact and minimizes bubble generation.
3、 Container transportation and positioning
1. Servo driven conveyor belt
The container is positioned by a photoelectric sensor, and the conveying speed is controlled by a servo system with a positioning accuracy of ± 0.5mm.
2. Automatic bucket/bottle system
Empty containers are automatically queued up on the conveyor line to enter the workstation, and are automatically removed after filling.
4、 Intelligent Control and Safety
1. PLC+HMI control
Touch screen setting parameters (filling volume, speed), supporting independent adjustment of single valve;
Store hundreds of formulas and adapt to multi category production.
2. Security protection
Explosion proof design (ATEX certification) for filling flammable liquids;
CIP/SIP online cleaning and sterilization comply with GMP standards.
5、 Typical process flow
Empty container conveying → precise positioning → filling valve probing → metering filling (negative pressure defoaming) → vacuum suction → container removal → sealing/labeling.
6、 Core technological advantages
1. Efficiency: Maximum filling speed of 800 barrels per hour (25L specification);
2. Flexibility: Modular design suitable for 10-50L containers;
3. Data traceability: Real time uploading of filling data to MES system, supporting full traceability throughout the process.
