Anti-drip filling nozzle
Sink filling, * back after filling to eliminate dripping wire drawing, and protect the cleanliness of the bottle mouth and conveying table.
P&M Promixer Automatic double-headed Rotary pump filling machine
This is a semi-automatic liquid filling machine that utilises constant-pressure feeding via a sealed pressure hopper combined with precise metering by a magnetically driven pump. The entire machine features a vertical structure made of 304 stainless steel, with a fully enclosed flow path design throughout. The equipment establishes a stable positive-pressure feeding environment via the top-mounted sealed pressure hopper, completely resolving the common issues of feeding fluctuations and air entrapment associated with standard self-priming magnetic drive pumps; Paired with a shaft-seal-free magnetic drive pump, it achieves zero-leakage transfer and precise metering, whilst the PLC touchscreen control system enables digital parameter adjustment.
Product Detail
Equipment Overview：
This automatic rotary lobe pump filling machine is a linear volumetric automatic filling equipment. The whole frame is made of 316 stainless steel. It consists of material hopper, sanitary rotary lobe pump metering unit, conveyor line and PLC touch‑screen control system.
Driven by servo rotary lobe pump for volumetric metering and conveying, it is suitable for medium‑to‑high‑viscosity materials. It can automatically complete bottle feeding, positioning and quantitative filling. It can connect with capping machine and labeling machine to build a complete automatic production line. Widely used in cosmetics, daily‑care, food and pharmaceutical industries for mass continuous production of syrup, lotion, cream, paste, gel and materials with fine particles.
Working Principle:
1.Material Feeding: Material is stored in the upper stainless‑steel hopper and flows into the rotary lobe pump chamber by gravity. For high‑viscosity material, optional hopper agitator assists feeding; external feeding tank is available for continuous material supply.
2.Rotary Lobe Pump Volumetric Metering: Servo motor drives the rotors inside lobe pump. Each full rotation delivers fixed volume of material. PLC sets rotation angle / turns to precisely control output volume and realize quantitative filling.
3.Bottle In‑Feed & Positioning: Conveyor belt transports empty bottles. Photo‑electric sensor detects incoming bottles, and bottle‑stopping mechanism locks bottles right below filling nozzle.
4.Filling Process: Filling nozzle descends into bottle. Rotary lobe pump starts to discharge material. Two‑speed filling is supported: high‑speed filling at first, then switch to low‑speed when approaching target volume to avoid foaming and splashing. Once preset volume is reached, the pump stops immediately. With non‑return structure and suck‑back function to prevent dripping and stringing.
5.Cycle Operation: After filling, nozzle lifts up, bottle‑stopper releases filled bottles to downstream. Next empty bottle moves into filling station for next cycle. No‑bottle‑no‑filling function avoids material waste caused by empty discharging.
Features：
1.Volumetric Metering by Servo Rotary Lobe Pump
Servo‑driven sanitary rotary lobe pump controls filling volume via rotor rotation angle. Stable filling accuracy against minor liquid‑level fluctuation. Compatible with materials containing fine solid particles.
2.Fully‑automatic Continuous Production with Conveyor Line
Equipped with belt conveyor, photo‑electric detection and bottle‑stopping positioning. Bottles are transported automatically. Can connect upstream and downstream equipment for complete production line.
3.Intelligent PLC & Touch‑Screen Control
Set filling volume, pump speed and delay time directly on HMI. Multiple product recipes stored for one‑click product changeover, simple commissioning.
4.Wide Viscosity Compatibility
Works for water‑based liquid, essence, lotion, cream, gel, paste, and materials with fine particles.
5.Two‑Speed Filling & Suck‑Back Anti‑Drip Design
High‑speed → low‑speed filling mode. Nozzle dives into bottle to reduce foaming & splashing. Pump suck‑back after filling eliminates dripping and stringing, keep bottles and conveyor clean.
6.Sanitary Quick‑Disassembly Structure
All wetted parts adopt 316L stainless steel. Rotary lobe pump can be quickly disassembled for cleaning & sterilization, meets GMP requirements for cosmetics and food.
7.Flexible Bottle Adaptation
Adjustable guide rail for different‑diameter plastic & glass bottles. Equipped with casters and leveling feet for easy moving and leveling.
8.Safety Protection
No‑bottle‑no‑filling logic, emergency stop button, fault alarm function to prevent waste from empty dispensing.
Double‑head rotor pump simultaneous filling
Dual‑pump dual‑station working for high throughput. Rotor pump handles high‑viscosity materials and products with fine particles.
PLC & Touch‑screen Intelligent Control
Store multiple product recipes, one‑click product switch, set temperature, filling volume, speed and delay parameters on screen.
Bottle Stop Positioning
The bottle stop mechanism releases finished bottles; it ensures that filling does not take place if no bottle is present, thereby preventing waste of materials caused by empty spraying.
Feeding Device
A piston cylinder driven by compressed air performs reciprocating motion; the feeding and discharging process is accomplished through changes in the piston chamber’s volume.
Conveyor Line
Features a non-slip chain conveyor system with adjustable guardrail width, ensuring stable transport of various types of glass and plastic bottles.
