Description

Single Head Screw Capping Machine is an automated or semi-automated device designed to apply and tighten screw caps or Roll-On Pilfer Proof (ROPP) caps onto containers, such as bottles, jars, or cans, with precision and efficiency. It is widely used across industries like pharmaceuticals, food and beverages, cosmetics, chemicals, and more for sealing containers made of materials like PET, PP, PVC, HDPE, LDPE, or glass. The Single Head Screw Capping Machine is a versatile, efficient, and reliable solution for applying screw caps to a wide range of containers. Its robust design, precise torque control, and automation features make it ideal for small to medium production lines across multiple industries. By integrating smart features like “No Bottle, No Cap” systems and quick changeovers, it enhances productivity while maintaining high-quality sealing standards.

Container Feeding: Bottles are transported on a conveyor belt and guided into the in-feed star wheel.

Cap Placement: The bottle picks up a cap from the delivery chute, fed by an automatic cap feeder.

Capping: The single capping head rotates and applies the cap with precise torque, sealing the container.

Output: Sealed containers are transferred to the outfeed conveyor for further processing.

Working Principle of Single 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 Features of Single Head Screw Capping Machine

Design and Construction:
- Built on a sturdy welded stainless steel frame, often enclosed with stainless steel sheets and doors for easy maintenance and compliance with cGMP standards.
- Adjustable height conveyor system to align with other production line equipment.
- Contact parts are made of durable materials like SS 304, Delrin, aluminum, or silicon to ensure hygiene and longevity.
- Compact and versatile, with some models featuring a matte finish for aesthetic appeal and corrosion resistance.

Operation:
- Containers are fed via a conveyor belt into an in-feed star wheel, which positions them precisely under the single capping head.
- Caps are automatically sorted and fed from a cap feeder through a delivery chute. The bottle picks up the cap, and the rotating capping head applies it with pre-set torque.
- Features a “No Bottle, No Cap” system to prevent cap wastage and ensure efficient operation.
- The capping head uses a magnetic clutch or servo motor for adjustable torque control, ensuring consistent sealing without damaging caps or containers.

Versatility:
- Compatible with a wide range of cap types, including flat caps, flip-top caps, child-proof caps, sport caps, and ROPP caps, with diameters typically ranging from 10–130 mm.
- Handles various container shapes and sizes with minimal or no changeover parts required.
- Suitable for industries like pharmaceuticals, food, beverages, cosmetics, chemicals, and lubricants.

Performance:
- Output typically ranges from 40–60 bottles per minute, depending on bottle and cap size. Some high-speed models can achieve up to 300 containers per minute.
- Equipped with a single motor that synchronizes the conveyor, star wheel, and platform turret for smooth operation.
- Includes safety features like a clutch on the star wheel to stop the machine if a bottle jams or overturns, and a photoelectric sensor to halt operation if no caps are detected in the chute.

Additional Features:
- PLC control with human-machine interface for intuitive operation and torque adjustment via a touchscreen.
- Quick format changeovers for different bottle or cap sizes, often taking less than 2 minutes.
- Optional features include toughened glass or acrylic safety cabinets, servo-controlled capping heads, and integration with filling or labeling machines for a complete production line.
