What Is a Screw Capping Machine?
A Screw Capping Machine is an automatic packaging machine used to place and tighten screw caps onto bottles and containers.
The machine receives bottles through a conveyor, positions or stabilizes the bottle, places the cap on the bottle opening and tightens the cap using a suitable capping mechanism.
Depending on the machine configuration, screw caps can be supplied manually, semi-automatically or through an automatic cap feeding and delivery system.
Working Principle
Bottle Infeed
Bottles enter the machine through an infeed conveyor and are transferred continuously toward the capping station.
Bottle Separation
A suitable spacing mechanism maintains the required distance between bottles before they enter the capping area.
Cap Feeding
For automatic operation, caps are supplied to a cap sorting and feeding system. The cap feeder or elevator delivers caps in the required orientation.
Cap Delivery
The oriented caps are transferred through a cap chute or delivery mechanism toward the bottle capping station.
Bottle Positioning
The bottle is positioned below the capping head to ensure correct alignment between the bottle neck and cap.
Cap Placement
The cap is placed onto the bottle neck before the tightening operation begins.
Screw Capping
The capping head engages with the screw cap and rotates the cap to tighten it onto the bottle neck.
Torque Control
The capping system can be configured to provide controlled tightening according to the cap and container requirements.
Cap Inspection
Where required, sensors or inspection systems can verify cap presence and capping conditions.
Bottle Discharge
After capping, the finished bottles move through the discharge conveyor toward the next packaging operation.
