Semi-Automatic Pneumatic 4-Head Vacuum Negative Pressure Liquid Perfume Filling Machine

Overview

The Semi-Automatic Pneumatic 4-Head Vacuum Negative Pressure Liquid Perfume Filling Machine is professionally engineered for low-viscosity, volatile daily chemical liquids including perfume, aromatherapy, toner, and toilet water. Adopting a fully pneumatic negative pressure vacuum filling principle with 4-station synchronous operation, it delivers superior explosion-proof performance, enabling safe processing of flammable and explosive materials such as alcohol and essence. Constructed with 304/316L food-grade stainless steel, the equipment features excellent corrosion resistance and easy cleaning. It effectively eliminates common filling defects including liquid overflow, bubble generation, and uneven filling levels through precision vacuum quantification technology. Equipped with switchable manual and semi-automatic operation modes, it flexibly accommodates laboratory sampling, small-batch trial production, and large-scale mass production. As a CE-certified device, it ensures stable, compliant and reliable performance for daily chemical product production and R&D.

Core Advantages

● Safe Explosion-Proof Performance: Adopting an all-pneumatic structure with no electric spark generation, the machine fully complies with modern daily chemical workshop safety standards, eliminating potential hazards during the filling of flammable and explosive raw materials.
● High Filling Efficiency: Four independent synchronous filling heads provide a stable production capacity of 20 to 40 bottles per minute, perfectly adapting to prototype testing, small-batch trial runs, and large-scale standardized production.
● Precise & Loss-Free Filling: Equipped with advanced negative pressure positioning technology, the machine achieves a filling accuracy of ±1mm for consistent liquid levels. The built-in residual liquid reflux system completely eliminates raw material waste.
● Dual-Mode Flexible Operation: It supports free switching between manual and semi-automatic modes. The semi-automatic mode is designed for continuous mass production, while the manual mode is ideal for sample testing, equipment debugging and the filling of special bottle types, enabling easy single-person operation.
● Sanitary & Low Maintenance: Material contact components adopt 316L stainless steel and the machine body uses 304 stainless steel, meeting international food and cosmetic hygiene standards. Quick-detachable pipeline structures enable dead-angle-free cleaning and prevent cross-contamination between different materials.
● Stable & Durable Performance: Equipped with a silent, voltage-stabilized pneumatic system, the machine operates smoothly with minimal vibration, guaranteeing high batch consistency, low failure rate, and extended service life.

Working Principle

This machine adopts a high-precision closed-loop filling system based on pneumatic negative pressure vacuum technology. Compressed air drives the vacuum generator to create stable negative pressure that automatically draws liquid materials into the filling pipeline. After the manual placement of empty bottles, the pneumatic pressing structure automatically seals the bottle mouths and initiates vacuum filling. When the liquid reaches the preset standard level, the negative pressure balances instantly to stop feeding, and excess liquid flows back to the storage tank through a dedicated reflux pipeline, realizing residue-free and loss-free closed-loop circulation. With an integrated dual-mode control system, the machine can switch freely between manual single-point control and semi-automatic continuous filling, fully adapting to sample debugging, small-batch production, and large-scale mass manufacturing scenarios.
