2. Core Main Features
2.1 High-Precision Load Cell Weighing Module Metering
This industrial filling machine is equipped with a professional industrial-grade precision load cell weighing module for 20L barrel filling. Different from traditional fixed-volume metering, weight-based metering is not affected by liquid density, temperature changes and material viscosity. It realizes real-time dynamic weighing and automatic material cutoff, with long-term filling accuracy stable within ±0.1%~±0.2%. The high-sensitivity load cell supports fine calibration and zero-point automatic correction, effectively avoiding cumulative errors in continuous production and ensuring consistent net weight of each 20L chemical barrel.
2.2 Explosion-Proof & Anti-Corrosion Industrial Grade Design
Aiming at the packaging characteristics of flammable and explosive chemical solvents, coatings and thinners, the whole machine adopts full explosion-proof electrical configuration, meeting industrial explosion-proof safety standards. The material contact parts are made of 304 stainless steel and anti-corrosion special materials, which can resist the corrosion of acidic, alkaline and organic chemical liquids. The fully sealed feeding pipeline and anti-splash filling nozzle prevent volatile chemical gas leakage and liquid splashing, ensuring safe and clean workshop production environment.
2.3 Dual-Speed Fast & Precise Filling Mode
The equipment adopts dual-stage filling logic of fast pre-filling and slow fine filling. Fast filling improves overall production efficiency, while low-speed fine filling effectively suppresses liquid surge and bubble generation, avoiding overflow and inaccurate final weighing. The intelligent system automatically matches filling speed according to material fluidity, realizing the perfect balance of high efficiency and high precision, which is very suitable for mass continuous filling production of 20L chemical barrels.
2.4 Full Automatic Intelligent Operation & Easy Maintenance
Equipped with PLC intelligent control system and touch screen human-machine interface, the machine supports one-key start, automatic barrel detection, intelligent weighing, automatic stop and fault self-alarm. Operators can preset target weight, filling delay and correction parameters, and store multiple production formulas for one-click switching. The modular load cell weighing module is detachable and independently calibrated, convenient for daily maintenance, parameter calibration and later replacement, greatly reducing equipment operation and maintenance costs.
2.5 Stable Anti-Shake Weighing & Anti-Interference Performance
The weighing platform is equipped with anti-shake and anti-vibration structure, which can effectively filter the vibration interference of workshop equipment and ground fluctuation. The high-stabilityindustrial weighing filling module ensures stable weighing data during dynamic filling, avoiding data jitter and inaccurate material stop caused by environmental vibration, maintaining long-term stable operation in complex industrial workshop scenarios.

8. Frequently Asked Questions (FAQ)
Q1: Why is weighing filling more accurate than volumetric filling for 20L chemical barrels?
Volumetric filling calculates capacity based on fixed volume, which is easily affected by liquid density, temperature and bubble content, resulting in large batch errors. Our 20L chemical barrel weighing filling machine adopts real-time load cell weight metering, directly taking product weight as the standard, which completely eliminates the influence of material physical characteristics and ensures ultra-high filling accuracy for chemical liquid packaging.
Q2: Can this machine fill different types of chemical liquids with different viscosities?
Yes. This industrial load cell weighing filling equipment has no restriction on material viscosity and density. It can freely adapt to low-viscosity solvents, medium-viscosity cleaning agents and high-viscosity coatings and curing agents. Users only need to adjust filling speed and weight parameters on the touch screen to complete product switching, realizing multi-material universal filling.
Q3: Does the load cell module need frequent manual calibration?
No. The industrial-grade load cell is equipped with automatic zero-point tracking and drift correction functions. During long-term continuous production, it can automatically eliminate zero drift caused by temperature change and equipment vibration. Regular manual calibration is not required, which greatly reduces daily maintenance workload and ensures stable long-term weighing accuracy.

Q5: What is the error range of long-term mass production filling?
Under standard working conditions, the long-term continuous filling accuracy of the equipment is stably controlled within ±0.1%~±0.2%. There will be no cumulative error with the increase of production quantity. It fully meets the net weight inspection standards of chemical finished products and avoids customer return and rework caused by unqualified filling weight.
Q6: Can this equipment be connected with automatic packaging assembly lines?
Yes. The machine adopts standardized linear layout and reserved docking interface. It can be seamlessly connected with automatic barrel arranging machine, capping machine, labeling machine, inkjet printer and conveying line to form a fully automatic 20L chemical barrel packaging production line.
