Automatic Multi Head Screw Capping Machine

The Automatic Multi Head Screw Capping Machine is a high-speed automatic bottle capping machine designed for continuous screw capping of bottles and containers. The machine uses multiple capping heads to simultaneously tighten screw caps, helping increase production output while maintaining consistent cap application.

The machine automatically feeds bottles, separates and positions containers, supplies screw caps and performs the capping operation through multiple synchronized capping heads. It is suitable for pharmaceutical, food, beverage, cosmetic, chemical and other industries using screw-type closures.

The Automatic Multi Head Screw Capping Machine can be configured according to bottle dimensions, cap specifications, required production capacity and packaging-line layout. It can also be integrated with automatic filling, induction sealing, labelling, coding and other downstream packaging equipment.

What Is an Automatic Multi Head Screw Capping Machine?

An Automatic Multi Head Screw Capping Machine is an automatic bottle capping system equipped with multiple screw capping heads for applying and tightening threaded caps onto bottles or containers.

The multi-head configuration allows several bottles to be capped during the operating cycle, making the machine suitable for higher-production packaging lines.

The machine can be supplied with automatic cap feeding, cap sorting, bottle positioning and controlled torque application according to the required packaging application.

Working Principle

Bottle Infeed

Filled bottles enter the machine through an automatic conveyor. The conveyor transfers bottles toward the capping station at a controlled speed.

Bottle Separation

A bottle separation mechanism creates the required spacing between containers before they enter the multi-head capping station.

Cap Feeding

Screw caps are supplied through an automatic cap feeding and sorting system. The cap feeder or elevator delivers correctly oriented caps toward the cap placement mechanism.

Cap $Placement

Caps are automatically positioned over the bottle necks before the bottles enter the screw capping section.

Bottle Positioning

The bottles are accurately positioned beneath the multiple capping heads to maintain consistent alignment during the tightening operation.

Screw Capping Operation

The multiple capping heads simultaneously engage with the caps and rotate them onto the bottle threads.

Torque Control

The capping system applies controlled tightening force according to the cap and bottle specifications. Torque can be adjusted according to the required closure performance.

Cap Tightening

The capping heads continue the tightening operation until the required cap position and torque are achieved.

Discharge

After capping, the finished bottles are released from the capping station and transferred through the discharge conveyor to the next packaging operation.
