Machine Overview and Functional Description
The automatic bottle filling and steam shrink sleeve packaging line is a complete integrated solution designed for the filling, labeling, and secondary packaging of bottled liquid, paste, and sauce products. The line combines multiple automated modules to ensure stable production, hygienic processing, and premium packaging presentation.
The process begins with the automatic bottle unscrambler, which automatically arranges disordered bottles into a uniform orientation for continuous conveying, significantly reducing manual bottle loading requirements.
Before filling, bottles pass through the UV sterilization tunnel, where ultraviolet disinfection effectively minimizes microbial contamination and improves packaging hygiene standards—particularly suitable for food, cosmetics, and healthcare products.
The system adopts a 4-head rotor pump filling machine, ideal for viscous liquids, pastes, and sauces containing soft particles. Rotor pump filling provides stable flow control, high filling accuracy, and gentle product transfer while minimizing material damage. Multi-nozzle synchronous filling substantially improves throughput.
Following filling, the automatic cap feeder and automatic capping machine complete cap sorting, feeding, and torque-controlled tightening, ensuring reliable sealing consistency for different cap specifications.
For product branding, the automatic sleeve labeling machine precisely positions shrink sleeves on bottles of various geometries, including round, square, flat, and irregular-shaped containers. The labels then enter the steam shrink tunnel, where uniform steam distribution delivers wrinkle-free, tight-fitting shrink performance, achieving superior aesthetics compared with conventional hot-air shrink systems.
The finished products can be further processed through the film sealing and heat shrink packaging system, enabling bundled secondary packaging for transportation, retail display, and carton packing.
The entire line features PLC intelligent control, modular integration, convenient maintenance, and scalable configuration, providing an efficient and reliable packaging solution for modern bottle production.

Structural Design and Working Principle
1. UV Bottle Sterilization System
The UV bottle sterilizer disinfects containers before filling using high-intensity ultraviolet irradiation. This process effectively reduces microbial contamination, improving hygiene compliance and product safety, especially for food, cosmetics, and healthcare applications.
2. 4-Head Rotor Pump Filling Machine
The four-head rotor pump filling system is specifically designed for high-viscosity liquids and sauces containing soft particles. The rotor pump ensures gentle product transfer, accurate volumetric filling, and synchronized multi-head operation for improved production efficiency.
3. Automatic Cap Feeding System
The automatic cap feeder efficiently sorts and delivers caps to the capping station. Adjustable mechanisms support various cap dimensions, reducing manual labor, minimizing downtime, and improving overall production consistency.
4. Steam Shrink Tunnel
The steam shrink labeling machine uses controlled steam circulation to achieve uniform sleeve shrinking without deformation or wrinkles. Compared with hot-air shrinking, steam technology provides tighter label conformity and superior visual appearance for premium packaging.
