Description

Four Head Screw Capping Machine is an automated piece of equipment designed to apply and tighten screw caps onto containers, such as bottles, jars, or cans, with high precision and efficiency. It is widely used across industries like pharmaceuticals, food and beverage, cosmetics, chemicals, and more for sealing containers with threaded caps. The machine is equipped with four capping heads, enabling it to process multiple containers simultaneously, offering higher throughput compared to single-head cappers.

The Four Head Screw Capping Machine is a robust, efficient, and versatile solution for medium to high-volume production lines. Its ability to handle various container types, cap sizes, and industries, combined with precise torque control and automation features, makes it a valuable asset for manufacturers.

Container Feeding: Bottles move along a conveyor belt and are guided into an in-feed star wheel.

Cap Placement: Caps are sorted and fed from a cap feeder into a chute, where the capping heads pick them up.

Capping: The star wheel aligns containers under the four capping heads, which descend, apply the cap, and tighten it to the pre-set torque.

Quality Check: Sealed containers are inspected to ensure proper capping before moving to the next stage.

Output: Capped containers exit via the conveyor for further processing.

Cap Elevator: For high-volume cap feeding.

Laminar Air Flow: For sterile environments.

Servo Control: For precise torque adjustments via touchscreen.

Integration: Can be paired with filling, labeling, or packaging lines for a complete solution.

Speed Variability: Output depends on bottle and cap size, with larger containers potentially slowing production.

Changeover Time: While quick, changing parts for different bottle/cap sizes requires some setup.

Initial Cost: Higher investment compared to single-head cappers, though justified by increased throughput.

Maintenance: Regular maintenance is needed for moving parts like capping heads and clutches to ensure consistent performance.

Working Principle of Four 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.

Key Components of Four Head Screw Capping Machine

Four Capping Heads:
- The machine features four rotating capping heads that apply screw caps to containers with precise torque control. Each head is designed to pick, place, and tighten caps, ensuring consistent sealing.
- Capable of handling speeds of approximately 40–80 bottles per minute, depending on bottle and cap size, shape, and material. Some advanced models can achieve up to 100–120 containers per minute.

Construction:
- Built with a sturdy stainless steel (typically SS304) frame, often with a matte finish, ensuring durability and compliance with cGMP standards for hygienic applications.
- Enclosed in stainless steel sheets with doors for easy access during maintenance.

Cap Feeding System:
- Utilizes a cap feeder to sort and deliver caps to the capping heads.
- Features like “No Bottle, No Cap” systems prevent cap application if no container is present, reducing waste and errors.

Conveyor and Star Wheel:
- Containers are fed via a conveyor belt into an in-feed star wheel, which aligns them precisely under the capping heads.
- A turret star wheel or similar mechanism ensures accurate positioning during the capping process.

Torque Control:
- Equipped with a clutch system to apply pre-set torque, preventing over-tightening or damage to caps and containers.
- Torque can be adjusted via a PLC or manually to suit different cap types and sizes.

Bottle Gripper and Stability:
