PLC programmable control provides multiple memory areas and scheme memory storage function, automatically storing filling measurements; fillings of the same medium and measurement are directly retrieved from the memory library without further adjustment.
8. The intuitive digital display is operated via a touch screen. Simply input the speed and the milliliters per bottle for direct filling; operation is simple and adjustments are quick.
9. A no-bottle-no-fill function is included. 10. User-friendly design, PLC control system, user-friendly interface, combined with frequency conversion speed regulation for linear adjustment, compact structure, and stable operation; it has a self- diagnostic function, with clear fault display and a high degree of automation. 11. Magnetic pump filling and cleaning are convenient and save materials; 9. Uses electrical and pneumatic components from world-renowned brands, resulting in low failure rate, reliable performance, and long service life. 10. The entire machine casing and parts are made of high-quality SUS304 stainless steel, while parts in contact with materials are made of 316 stainless steel and solvent-resistant pipes, making it aesthetically pleasing; safe to operate, stable, and durable.

Explosion-proof filling machines are widely used in various industries for filling volatile and explosive liquids. They provide a safe production environment and ensure worker safety. They are commonly used for lighter fuels, kerosene, blended fuels, industrial alcohols, n-butanol, and diethyl carboonate.

1. Bottle unscrambler/bottle feeder (front-end equipment): They are responsible for sorting the empty bottles and feeding them into the production line in order to prepare for filling: the transparent protective cover can isolate dust. prevent accidental contact. and also meet the safety protection requirements of explosion-proof scenarios.
2. Explosion-proof filling machine main unit: The core of the entire production line is responsible for accurately filling materials into bottles. It integrates filling valves and metering systems, and the entire machine is designed according to explosion-proof standards to avoid safety hazards during the production of flammable and explosive materials.
3. Explosion-proof control box: The “brain” of the production line includes a PLC control system, a touch screen, and emergency stop/ start buttons. All electrical components are explosion-proof and are used to set parameters and monitor operating status.
4. Audible and visual alarm indicator: Used to indicate the equipment’s operating status, it will issue an audible and visual alarm when there is a malfunction, material shortage, or filling abnormality, reminding the operator to take action.
5. Conveyor line (with explosion-proof drive motor): Connecting various processes, it transports bottles from bottle sorting and filling to the next workstation. The part marked “Ex” in the diagram is an explosion-proof geared motor, specifically designed for flammable and explosive environments to prevent electrical sparks from causing danger.
6. Pneumatic system air tank: Provide a stable air supply for the pneumatic actuators of the equipment (such as cylinders and filling valves) to ensure stable operation of filling, capping and other actions.
7. Finished Product Transition/ Inspection Workbench: The filled bottles are temporarily stored here or undergo preliminary appearance and liquid level inspections before proceeding to subsequent processes (such as capping and labeling).
8. Samples of finished products awaiting filling / already filled: The black bottle with a red cap in the picture is the product container that this line is compatible with, used to show the compatibility specifications of the equipment.

Ensuring safety: The motor, electrical box, wiring, and drive unit are all equipped with BT4 explosion-proof rating, ensuring explosion protection throughout the entire process from filling to capping, eliminating potential safety hazards. Suitable for filling all flammable and explosive liquids of Class A, B, and C.

Reduces costs and increases efficiency: Double protection to prevent material waste. Special leak-proof filling nozzle + drip tray, double anti-drip design. No stringing or dripping during filling, saving customers tens of thousands of yuan in material waste annually, while maintaining a clean working environment.

Accuracy ±1%: Accurate measurement, every bottle is standardized. The magnetic pump, combined with PLC control, ensures filling accuracy within ±1%. It automatically stops filling when no bottle is available and automatically stops when a bottle is missing, avoiding waste from empty fillings and ensuring consistent content in every bottle.

Quick and thorough cleaning: 316L stainless steel + solvent-resistant pipe. All parts in contact with materials are made of 316L stainless steel and solvent-resistant hoses. The magnetic pump structure allows for quick disassembly and cleaning, completing product changeover cleaning within 30 minutes with no material residue, meeting the needs of multi-variety production.

Branded components, durable: International top-tier brand, low failure rate.

• Electrical components: Schneider Electric (France)
• PLC/Touchscreen: Delta Electronics (Taiwan)
• Pneumatic components: Airtac (Taiwan)
• Photoelectric sensors: Keyence (Japan)

The entire machine is designed for a lifespan of over 10 years, with stable and reliable core components, reducing subsequent maintenance costs.

Tips for Maximizing Efficiency and Performance
It is important to measure and ensure the maximum efficiency of your machine to achieve ultimate profit out of your production. A few tips can boost your machine’s performance in the long run. Additionally, you will find your explosion-proof filling machine a more cost-effective tool over its lifespan.

• Regular maintenance is a must to ensure all intrinsically safe components and seals are in optimal condition.
• Regular calibration is similarly important to maintain filling accuracy, prevent product giveaway, and ensure consistent volume control.
• Use high-quality consumables and OEM spare parts, such as specialized seals, gaskets, and anti-drip filling nozzles.
• Optimize filling parameters by experimenting with different flow rates, diving nozzle speeds, and container profiles.
• Make sure the containers are properly aligned and the grounding system is securely connected before starting the cycle.
• Train the operator on the PLC interface, recipe management, and advanced safety features.
• Monitor performance metrics, cycle times, and weight accuracy routinely to prevent costly downtime.
