Product Introduction
This integrated liquid detergent bottling packaging line adopts linear servo piston filling structure with standard anti-drip suck-back
nozzles to avoid stringing and dripping contamination on bottles and conveyor belts. The whole line integrates filling unit, servo screw
capper, self-adhesive labeler, carton erector and case packer, matched with conveyor and PLC central control system. It automatically
and continuously performs bottle filling, screw capping, bottle labeling, carton erecting and finished bottle packing. Wetted parts are
food-grade stainless steel, suitable for medium & low viscosity daily care liquid. Stable operation and quick format change, ideal for
continuous automatic packaging of medium and small daily chemical factories.
Main Advantages
✅ Anti-drip suck-back nozzle: synchronous suck-back after filling, clean cut-off, no dripping or stringing
✅ Servo piston volumetric filling: high filling accuracy, stable flow, wide viscosity range
✅ Full-process automatic interlock: filling-capping-labeling-erecting-case packing interlocked, no bottle no filling
✅ Sanitary grade construction: SUS316L liquid contact parts, SUS304 frame, corrosion resistant, easy disassembly & cleaning
✅ Servo torque capping: adjustable torque, consistent tightening, prevent leakage, suitable for screw caps and pump caps
✅ Quick changeover design: scaled adjustment components, less disassembly for bottle & label change
✅ PLC+HMI touch control: one-click parameter setting, fault alarm, easy operation & maintenance
✅ Modular design: each unit can run independently; coding, carton sealing, palletizing can be added later
