1.2 Standard Automatic Workflow

1. Automatic bottle sorting & conveying: Bottle unscrambler arranges messy bottles neatly onto conveyor belt; photoelectric sensor detects bottle position
2. Quantitative filling: Multi-head piston/peristaltic pump quantitative filling; dive filling nozzle prevents foaming and splashing
3. Cap auto feeding: Vibratory cap feeder arranges caps uniformly; cap inspection sensor rejects missing caps
4. Automatic capping & torque control: Servo capping head tightens caps with fixed torque; no bottle no filling interlock protection
5. Finished bottle discharge: Conveyor sends finished bottles to next station (labeling, coding, packing)

All steps are controlled by PLC+HMI touch screen; all production parameters can be saved as formulas for one-click switching of different products.

5. Seven Must-Check Selection Standards to Avoid Procurement Mistakes

Based on after-sales data of packaging machinery export business, 70% of customer equipment problems are caused by wrong selection instead of machine quality. Summarize 7 purchasing judgment rules for overseas buyers:

1. Confirm liquid viscosity first: Thin liquid chooses peristaltic pump; medium/high viscosity chooses servo piston pump; do not mix pump types
2. Clarify bottle material and shape: Irregular square/hexagonal bottles need customized bottle clamping fixtures; ordinary round bottles use standard universal fixtures
3. Confirm cap type and size: Flip cap, screw cap, press cap correspond to different capping heads; inform cap diameter before ordering
4. Calculate required hourly output: Match filling head number (low speed 2-head, medium speed 4-head, high speed 6/8-head)
5. Compliance requirement confirmation: Export to EU/US needs CE certification; pharmaceutical industry requires FDA/GMP material certification
6. Factory site condition: Small narrow workshop chooses compact shortened model; normal workshop selects standard size to reserve space for follow-up labeling/coding connection
7. Special liquid demand: Flammable liquid requires explosion-proof configuration; easy-crystallization liquid needs heating insulation hopper

6. Operation, Parameter Debugging & Daily Maintenance Manual

6.1 Fast Parameter Debugging Steps for 500-1000ml Specification

1. Enter touch screen formula interface, create new recipe named with product name
2. Adjust filling stroke (piston pump) / pump rotation time (peristaltic pump), calibrate volume with graduated cylinder; calibrate repeatedly until error within ±0.5%
3. Adjust conveyor width according to bottle diameter; adjust cap feeder vibration amplitude for smooth cap sorting
4. Set servo capping torque: Plastic cap 1.2–3N·m; glass bottle metal cap 3–5N·m; too high torque cracks caps/bottles, too low causes leakage
5. Turn on photoelectric protection function: No bottle stop filling, no cap alarm stop machine

6.2 Daily Maintenance Checklist

1. End of daily production: Disassemble filling pipeline and nozzles, rinse with clean water/medical alcohol, prevent material residue curing and blockage
2. Weekly inspection: Check air pressure pipeline air leakage, conveyor chain tightness, capping head bearing lubrication
3. Monthly maintenance: Calibrate filling accuracy once; check PLC and servo motor wiring stability
4. Long-term shutdown: Empty all liquid pipelines, fully clean, coat stainless steel surface with anti-rust oil
