China Full Automatic Bottle Liquid Linear Piston Filling Machine (YBG)

Product Description

4-Head Servo-Driven Sauce Filling Machine

Designed for chunky or viscous sauces (beef sauce, mushroom sauce, doubanjiang, tahini, sweet bean paste), this 4-head servo-driven machine offers 100-500 g fill range with ±1% accuracy and up to 3000-4000 bottles/hr throughput. All-SS 304 exterior and 316L product-contact parts ensure corrosion resistance and easy sanitation. PLC & DLP touchscreen control enables one-touch changeover between container sizes and filling recipes. Gravity-fed, anti-drip filling heads with lift mechanism guarantee no stringing, no splatter, and no contamination.

Working Principle & Operation:Container Loading:

Operators or the unscrambler place empty sauce bottles onto the conveyor. A sensor detects bottle presence and signals the PLC to start the fill cycle.Auto Tare & Calibration:
The PLC performs automatic tare (zeroing) on the load cells and loads the selected recipe parameters-target weight, fast/slow fill rates, air pressure, and capping torque.Dual-Speed Weigh Filling:
The servo-controlled valve opens fully for theFast Fill Stage, rapidly filling to about 95-98% of target weight. InSlow Fill Stage, the PLC switches to slow flow for fine-tuning, maintaining ≤±1% precision.Anti-Drip Nozzle Retraction:
Once the target weight is reached, the filling valve closes instantly and the nozzle retracts. An optional air-blow-off device can clear residual sauce to prevent drips or stringing.Inner-Plug Insertion:
After filling, bottles move to the inner-plug station. The PLC triggers a pneumatic cylinder to insert a liner or foil seal into the bottle mouth, creating a tamper-evident, leak-proof barrier.Automatic Screw Capping:
Bottles advance to the capping station. A vibratory cap feeder aligns caps and places them on a turret. Servo-driven capping heads pick up each cap and tighten it to the torque set on the HMI (5-15 Nm), ensuring no missing caps or over-tightening.Outfeed & Collection:
Capped and sealed bottles exit via the outfeed conveyor, moving on to labeling, coding, or direct packing-ensuring high-efficiency, continuous operation.Real-Time Monitoring & Alarms:
The HMI displays live data-each fill head's weight, fill speed, capping torque, air pressure, and any fault codes. If any parameter deviates beyond set limits, the PLC halts the line and triggers an alarm, prompting operator intervention.

Frequently Asked Questions (FAQ):

Q:How do I switch between different viscosities?

A: Select the desired recipe on the touchscreen; the system auto-adjusts servo valve settings and fill speed—no manual parts swap required.

Q:How do the filling heads prevent stringing and dripping?

A: ravity-fed lift-up filling heads combined with anti-drip valves automatically lift and close at the end of fill, preventing stringing and drips.

Q:How to change container sizes within minutes?

A: Use pneumatic quick-release guards and adjustable fixtures—simply release clamps and adjust holders to fit new bottle sizes in minutes.

Q:How is ±1% fill accuracy maintained?

A: Servo valves precisely control flow, load cells provide real-time weight feedback to the PLC, and the system auto-fine-tunes the cut-off to achieve ±1% accuracy.

Q:How do I clean and sanitize the machine?

A: All product-contact parts are detachable and CIP-ready for in-place rinsing. Alternatively, remove components for manual high-pressure wash to complete quick sanitation.
