Product Overview:

This production line integrates dual-head liquid weighing filling units with automatic inner plug insertion and outer capping stations, ideal for 5–50 kg filling of liquids, creams, and sauces. PLC control with photoelectric sensors automatically stops, tars, fills, and caps when a container arrives. All stainless-steel construction meets high hygiene standards; gravity filling prevents drips. Suited for food additives, curing agents, industrial cleaners, motor oils, flavorings, pesticides, and veterinary drugs.

Key Features:

Dual-Head Weighing Filling:Each head features a high-precision load cell and dual-speed fill valve (fast/slow) for high throughput and ±0.3% accuracy.

Automatic Inner Plug & Outer Capping:Automatically inserts inner plugs and torques outer caps; capping torque is adjustable to meet container requirements.

PLC & Touchscreen Intelligent Control:Siemens PLC programming with full-color touchscreen HMI allows one-touch settings for fill weight, fill speed, and capping torque.

Anti-Drip Gravity Filling:Gravity-fed filling with anti-drip valve ensures clean, drip-free operation.

All-SS Sanitary Construction:Main frame, hopper, filling valves, and contact parts are all 304/316L stainless steel, meeting food-grade sanitary requirements.

Compact Inline Conveyor:Compact inline chain conveyor supports 5–30 L various plastic barrels and bottles, including irregular shapes.

Rapid Changeover:Quick-release fittings, pneumatic clamps, and adjustable guards enable container size changes within 5 minutes.

Working Principle & Operation:Container Loading:
Operators or an unscrambler load empty bottles onto the conveyor. A photoelectric sensor detects bottle presence and signals the PLC to begin the fill cycle.Auto Tare & Zeroing:
The PLC automatically tars (zeroes) the optional weighing platform and loads the fill recipe (fill volume, flow rate, head count).Gear Pump Self-Priming Filling:
Gear Pump Self-Priming Filling: VFD-driven gear pumps deliver precise, constant flow. Nozzles positioned above bottle mouths fill based on time or weight, achieving ≤0.1% error.No-Bottle, No-Fill Safety:
If no bottle is detected by the photoelectric sensor, the PLC inhibits pump activation and triggers an alarm-preventing dry runs or overfills.Real-Time Parameter Monitoring:
The HMI shows live fill-head status, filling rate, total bottle count, and alarm notifications. If any parameter exceeds preset limits, the PLC stops the line and issues an alert.Outfeed & Collection:
Filled bottles exit via the outfeed conveyor to downstream stations-labeling, coding, or direct packing-enabling efficient continuous operation.
Quality & Certification:
Certifications:CE,UL,ISO 9001
QC Process:Incoming Inspection - Inspect SS 304 sheets, magnetic gear pumps, VFD controllers, and pneumatic components for material and performance compliance.
In-Process Inspection - Verify gear pump flow rates and potentiometer speed settings during assembly to ensure consistency across all channels.
Full-Load Trial Run - 12-hour continuous full-load test to confirm stable parallel filling by 6 heads without faults.
Final Factory Inspection - Conduct sample fill tests with actual liquids to verify ≤±0.1% deviation and issue QC report.

Frequently Asked Questions (FAQ):

Q: Why is no overhead tank required?

A: Self-priming gear pumps draw fluid directly from supply drums—eliminating the need for elevated tanks, simplifying piping, and reducing fluid exposure.

Q: How is ±0.1% fill accuracy achieved?

A: VFD drive and multi-turn potentiometer precisely regulate pump speed, combined with PLC-timed fill durations accurate to milliseconds.

Q: What types of liquids can it handle?

A: Suitable for medium to high-viscosity liquids (≤2000 cps) and general fluids, such as pharmaceutical solutions, oils, cosmetics, soy sauce, and chemical reagents.

Q: How long does changeover take?

A: Guide rails and fixtures adjust without part changes, enabling bottle size changeover in 3–5 minutes.

Q: How are the pumps and piping cleaned?

A: Removable pump heads and SS piping support CIP or manual high-pressure wash, providing quick and thorough cleaning.

Q: Can more filling heads be customized?

A: Yes—head counts can be customized to 8, 10, 12, 14, etc., to achieve higher throughput as needed.
