Analysis of working principle of spray filling production line
Date: 2025-09-17Read: 4
Spray filling production line plays an important role in the packaging production of spray and aerosol products in pharmaceutical, daily chemical, chemical and other industries. Its efficient and stable working principle supports the orderly progress of the entire production process.
Working principle of spray filling production line:
This production line is suitable for packaging spray products in pharmaceutical, daily chemical, chemical and other industries, and realizes stable production with automated processes. The core links are as follows:
1. Bottle pretreatment
• Bottle management: the fully automatic equipment sorts and arranges the disordered spray bottles and transports them to the next station one by one, replacing manual bottle loading, improving efficiency and accuracy.
Gas washing: Rinse the bottle with purified gas to remove dust and debris; Paired with an electrostatic elimination ion air rod to prevent the adsorption of impurities by static electricity from affecting quality.
2. Filling process
Adopting a plunger metering pump, it is suitable for liquids of different viscosities such as water agents and pastes. The pump body is designed with quick connect disassembly for easy cleaning and production replacement. It can also be equipped with a pump set that supports CIP/SIP.
Driven by a servo motor, the pump body is precisely controlled to operate according to the filling volume set on the human-machine interface; The filling needle is equipped with an anti drip device, which penetrates into the bottom of the bottle and slowly moves up as the liquid level rises, reducing the generation of bubbles.
3. Upper cover and rotary (rolled) cover
Upper cap: The robotic arm precisely places the cap onto the bottle mouth through a slender tube, relying on a guiding system to ensure stable placement.
• Rotary (rolling) cap: The mechanism drives the rotary cap head/rolling cap device to rotate and move up and down through mechanical transmission, achieving sealing; Parameters can be adjusted according to product requirements to adapt to different specifications of bottle caps.
4. Post processing and packaging
Aerosols require additional inflation; Subsequently, complete the installation of the large cap and labeling (marking key product information).
After being boxed and boxed, the finished products are neatly stacked on pallets by palletizing equipment for easy storage and transportation.
The entire line is coordinated by a PLC control system, and operators monitor and adjust production speed, filling volume, and other parameters through a human-machine interface to achieve automated operation.
