1. Product Overview

Product Category

  • Product Name (EN): Automatic Four Heads Liquid Filling Machine
  • Category: Packaging Machinery / Piston-Type Automatic Liquid Filling Machine
  • Automation Grade: Fully Automatic
  • Drive Type: Pneumatic + Electric (servo or pneumatic piston)

Applications

  • Food Industry: Edible oil, juice, sauce and other liquid food products.
  • Daily Chemicals: Shampoo, dishwashing liquid, hand soap and similar viscous daily-care products.

4. Sales Tips & FAQ

Sales Tips

Model Recommendation

  • Recommend the model based on the upper limit of the customer's bottle capacity.
  • Example: For bottles from 200 ml to 800 ml, recommend the A4-1000 for the best accuracy coverage — its 100–1000 ml range covers the full SKU spectrum without switching models.

Bundle Guidance

  • Combine with a capping machine and labeling machine to form a fully-automatic production line, increasing the average order value.
  • For corrosive materials, upsell the 316L stainless steel or Teflon coating customization option.
  • For high-viscosity or easily-solidifying materials, recommend the hopper heating & stirring add-on.

FAQ

Q1: Does the machine support corrosive liquids? A: Yes. For corrosive materials, we provide a full 316L stainless steel build or anti-corrosion Teflon coating customization to protect the machine and ensure long service life.

Q2: Is installation and training difficult? A: Not at all. The machine is fully debugged before shipment — out-of-the-box installation. Detailed video guides plus online one-on-one engineer support are provided.

Q3: Can heating and mixing functions be added? A: Yes. For high-viscosity or easily-solidifying materials, we can customize the hopper heating and stirring device to keep material flowable during filling.

Q4: How is the filling accuracy guaranteed? A: The piston-type quantitative dosing combined with a Taiwan-brand PLC keeps filling error within ≤ ±1%. Airtac pneumatic components and SICK photoelectric sensors further stabilize the cycle for consistent results.

Q5: Can the number of filling heads be customized? A: Yes. The machine supports 2/4/6/8 head configurations. The standard A4 series ships with 4 heads; other head counts are customizable on request.

Q6: What is the difference between A4-2500 and the other models? A: The A4-2500 covers the 250–2500 ml range and runs at 10 – 30 cycles/min (slightly slower than the 10 – 40 cycles/min of the other models). It also weighs 400 kg vs. the 330–334 kg of the smaller models, due to the larger piston cylinder and frame.

Q7: What certifications does the machine have? A: The machine is CE certified (Certificate No: B-S15047199). Materials comply with GMP standards for food-contact applications.

6. Workflow

Step-by-Step Operation

Step 1                Step 2              Step 3                Step 4              Step 5
Bottle Feeding  →   Counting & Stop  →   4-Head Synchronized  →   Anti-Drip    →   Bottle Discharge
                                    Filling                           Handling

Step 1 — Bottle Feeding

  • Equipment: Infeed conveyor
  • Operation: Empty bottles enter the machine on the conveyor automatically.
  • Key Point: Ensure bottles are oriented correctly and spaced evenly on the belt before they reach the counting station.

Step 2 — Counting & Positioning

  • Equipment: Inlet photoelectric sensor + bottle-stop cylinder
  • Operation: The inlet photoelectric sensor counts bottles as they pass. Once 4 bottles are detected, the bottle-stop cylinder extends to lock the bottles in precise filling positions.
  • Key Point: Sensor sensitivity must be calibrated to the bottle diameter; miscounts will trigger the no-bottle-no-fill protection.

Step 3 — 4-Head Synchronized Filling

  • Equipment: 4 filling heads + servo/pneumatic piston cylinders
  • Operation: The 4 filling heads descend simultaneously; the pistons push material to fill all 4 bottles in one synchronized cycle.
  • Key Point: Filling volume is set on the touchscreen; Airtac pneumatic components ensure consistent pressure across all 4 heads for ≤ ±1% accuracy.

Step 4 — Anti-Drip Handling

  • Equipment: Positive shutoff valve + filling head lift cylinder
  • Operation: At the end of each filling cycle, the positive shutoff valve closes and the filling heads lift, ensuring zero dripping and no residue on the bottle mouth.
  • Key Point: The cut-off valve design eliminates dripping at high cycle speeds — a clear upgrade over spring-return valves.

Step 5 — Bottle Discharge

  • Equipment: Outlet conveyor + next-stage equipment (capping / labeling)
  • Operation: The bottle-stop cylinder retracts and the filled bottles move forward on the conveyor to the capping or labeling station.
  • Key Point: For a fully-automatic line, sync the discharge conveyor speed with the downstream capping machine to avoid jams.

Production-Line Recommendations

  • Operators: 1 – 2 (1 monitoring the HMI, 1 doing visual quality check and bottle supply)
  • Cycle Time: 10 – 40 cycles/min (10 – 30 cycles/min for A4-2500)
  • Floor Space: Reserve a 3 × 2 m² area for the host machine, plus line space for conveyors and downstream equipment
  • Supporting Equipment: Air compressor ≥ 0.8 MPa, ≥ 400 L/min
  • Recommended Line Layout: Infeed conveyor → A4 filling machine → Capping machine → Labeling machine → Collection table
