Working Principle of Eight Head Screw Capping Machine

The filled bottles moving on conveyor belt and fed into an in feed star wheel by in-feed worm. While moving in feed star wheel, bottles pick up caps one by one from delivery chute. The descending rotary sealing heads hold bottle’s neck with desired pressure. The sealing is done in a programmed roll-on manner, accurate positioned of the caps is done mechanically by means of a rotating unscramble, to direct the caps correctly into the chute, when the chute is filled up the rotating unscramble drive is disengaged, hence, there is no chance to damage of caps. The sealing roller takes place due to rotating sealing head and transfer movement of sealing & threading rollers due to sealing cam. The sealed bottles are discharged by exist star wheel on conveyors.

Applications of Capping and Sealing Machine

Benefits of Eight Head Screw Capping Machine

High Efficiency: The eight-head design significantly boosts production speed, making it ideal for large-scale operations.

Versatility: Handles various bottle shapes, sizes, and cap types with minimal changeover time.

Reliability: Precision engineering and safety features ensure consistent performance and minimal downtime.

Durability: Stainless steel construction ensures long life and resistance to corrosion, meeting strict industry standards.

Automation: Fully automated systems reduce labor costs and improve production line efficiency.

Key Features of Eight Head Screw Capping Machine

Construction and Design:
- The machine is built on a sturdy welded mild steel (MS) or carbon steel frame, fully enclosed in stainless steel (SS 304) sheets for durability, corrosion resistance, and compliance with hygiene standards.
- It features adjustable stainless steel legs for height customization, ensuring compatibility with different production lines.
- Doors are provided for easy access during maintenance and servicing.

Operation:
- Bottle Feeding: Containers move along a conveyor belt and are fed into an in-feed star wheel. The star wheel aligns containers precisely under the capping heads.
- Cap Placement: Caps are delivered from a cap feeding system via a delivery chute. The rotating capping heads pick up caps and position them on the container’s neck.
- Capping Process: The eight capping heads, often equipped with magnetic hysteresis clutches or servo motors, apply caps with precise torque control to ensure a tight, leak-proof seal without damaging the cap or container threads.
- Output: The machine then transfers capped containers to an exit star wheel and onto the conveyor for the next process.

Performance Specifications:
- Bottle and Cap Compatibility: Suitable for round, square, or other shaped bottles with a maximum bottle diameter of ~85 mm, height of ~300 mm, and cap size up to ~32 mm. Change parts allow quick adjustments for different sizes.
- Pass Rate: Achieves a high stand-alone pass rate of up to 99%, ensuring reliable capping.

Advanced Features:
- No Bottle, No Cap System: Prevents cap application if no container is present, reducing waste and jams.
- No Cap, Machine Stop System: A background suppression sensor halts the machine if no caps are detected in the delivery chute, enhancing operational safety.
- Torque Control: Magnetic hysteresis clutches or servo motors provide precise torque adjustment, ensuring consistent sealing without over-tightening. Servo-controlled systems allow digital torque settings via a touchscreen interface.
- Safety Features: Includes safety clutches at the star wheel and feed worm to prevent bottle breakage, emergency stop buttons, and CE-certified electrical components.
- Cap Feeding Options: Supports vibratory feeders, mechanical cap feeder orientators, or waterfall-type elevators for continuous cap supply.
- Fast Changeover: Custom-designed parts enable quick format changes between different bottle and cap sizes, minimizing downtime.
- Low Noise and Power Efficiency: Operates at low noise levels and consumes modest power.

Applications:
- Ideal for sealing plastic screw caps, ROPP caps, or other threaded closures on various containers.
- Used in industries such as pharmaceuticals, food and beverages, cosmetics, chemicals, and pesticides.

Additional Features:
- PLC and Touchscreen Control: Many models feature a 7” color touchscreen with PLC for intuitive operation, error messaging, and production monitoring.
- Integration: Can be seamlessly integrated with filling, labeling, and other packaging line equipment for fully automated production.
