For manufacturers requiring reliable, high-speed capping solutions, the Fully Automatic Four-Wheel Screw Capping Machine delivers exceptional performance. Designed with a rotary four-wheel capping mechanism, this machine applies screw caps with consistent torque, ensuring each container is sealed securely without cross-threading or damage.
Unlike traditional single-head or chuck-style cappers, the four-wheel design provides superior grip and stability during the capping process. The cap is guided and tightened by four synchronized rotating wheels that gently yet firmly secure the closure. This design is particularly effective for applications requiring precise torque control—such as cosmetic bottles, pharmaceutical vials, beverage containers, and household chemical packaging.
The system is fully controlled by a PLC with a touch screen interface, allowing for quick setup, torque adjustment, and real-time production monitoring. Constructed with a durable stainless steel frame and food-grade components, this capping machine meets GMP standards for cosmetic, pharmaceutical, and food manufacturing environments.
1. Four-Wheel Rotary Capping Mechanism
The machine features four synchronized capping wheels arranged around the container neck. As bottles pass through the capping station, the wheels rotate to tighten caps with consistent torque. This design provides excellent stability and prevents caps from tilting or cross-threading—even at high speeds.
2. Precise Torque Control
The capping torque is easily adjustable via the touch screen interface or mechanical adjustment. This allows operators to fine-tune the tightening force for different cap sizes, materials, and closure requirements—ensuring secure seals without over-tightening or damaging caps.
3. Versatile Cap & Bottle Handling
Designed to accommodate a wide range of screw cap types and container sizes:
Cap Diameter: 15mm – 80mm (customizable)
Bottle Height: 50mm – 300mm (adjustable)
Bottle Diameter: 20mm – 120mm (adjustable)
The machine handles various cap styles including flat caps, pump caps, child-resistant closures, and sports caps.
4. High-Speed Operation
With capping speeds of up to 40–80 bottles per minute (depending on bottle size and cap type), this machine significantly improves production throughput compared to manual or semi-automatic capping methods.
5. Automatic Cap Feeding
The system is equipped with a vibratory cap elevator or sorter that automatically orients and feeds caps to the capping station. This eliminates manual cap placement and ensures continuous operation.
6. No-Bottle-No-Cap Function
Integrated sensors detect the presence of bottles at the capping station. If a bottle is missing, the machine automatically skips cap feeding, preventing waste and ensuring smooth operation.
7. User-Friendly Control System
The PLC and HMI touch screen provide intuitive operation, recipe storage for up to 100 different products, and real-time diagnostics. Changeover between different bottle and cap sizes typically takes less than 15 minutes.
8. Durable & Hygienic Construction
The machine frame is constructed from SUS304 stainless steel, while all product-contact and wear parts are designed for durability and easy cleaning. The stainless steel design ensures corrosion resistance and compliance with sanitary standards.
Bottle Feeding: Containers enter the capping station via the stainless steel conveyor, guided by adjustable rails.
Cap Feeding: The vibratory cap elevator orients and feeds caps to the capping head. Caps are presented to the waiting bottles.
Cap Placement: A cap placement mechanism positions the cap onto the bottle neck.
Four-Wheel Tightening: The four capping wheels descend and rotate simultaneously, gripping the cap and tightening it to the preset torque. The synchronized wheels ensure even pressure and prevent cross-threading.
Bottle Discharge: Capped bottles continue along the conveyor to the next production stage (labeling, packaging, etc.).
