This integrated packaging line combines a four-head gear pump filling machine, a press-on capping machine, and a round bottle positioning labeling machine into a single automated system. The four-head gear pump filling station is designed for precise and efficient filling of medium to high-viscosity liquids and pastes. The press-on capping mechanism securely applies caps onto bottles with consistent pressure, ensuring a leak-proof seal. The round bottle positioning labeling system accurately applies labels to the circumference of cylindrical containers. The entire line is connected by a conveyor belt for seamless, continuous operation. Each module features its own touchscreen control panel for independent adjustment and monitoring.
