bottle screw capping machine


screw capping

The capping machine automatically presses and screws lids on bottles. It pushes the caps more precisely and avoids damage to the caps. This machine is more effective than intermittent capping. 

Its continuous capping design allows it to adjust to different packing line speeds. Usual bottles and screw caps come in any shape, material, or size. This machine can be used for different purposes and is simple to operate.

Working Principle

The cap control system positions and hangs the cap sideways at a 30° angle. The bottle separator divides the bottle by passing through the cap area, bringing the cap down and covering the bottle opening. The bottle moves forward on the conveyor belt, and the capping belt secures the cap as it passes through three pairs of capping wheels.

The capping wheels apply pressure to both sides of the cap, tightening the cap and completing the capping procedure of a bottle.

Bottle clamp belt


-The conveyor raises the caps, and the blower blows them into the track.

-Cap feeders start and stop automatically in response to sensor detection.

-The incorrect cap sensor can readily detect inverted caps. The bottle sensor and automatic lid remover assure correct capping.

-A bottle separator can be used to modify the speed at which bottles are conveyed.

Efficient & Easy Operate

-The linear conveyor and automatic cap feeding can reach speeds of up to 100 bpm.

-Three pairs of wheels swiftly twist caps off. To quickly manufacture caps in the correct position, the first pair can be set into a reverse turn.

-Easy-to-use PLC with touch screen control.

-Press the emergency stop button to stop the machine.

efficient, easy operate


-A single button controls the overall height of the capping device.

-Wheels that allow you to modify the width of the bottle capping track.

-Modify the cap feeder, bottle conveyor, capping wheels, and bottle separator speeds.

-Use the switch to adjust the speed of each set of capping wheels.

Working Process

The two main components are the capping section and the lid feeding section.

Bottles arrive (can be connected to the auto packing line) Convey  → bottles at a similar distance  → Raise lids  → Place lids on  → Lids are screwed on and pressed → Bottles are out

1.What Is The Function of Each Part of Bottle Capping Machine?


-The blower blows caps into the cap track after the conveyor has brought caps to the top.

-The cap feeder’s automatic running and stopping is controlled by a cap lack detecting device. Two sensors are located on opposite sides of the cap track, one to determine if the track is full of caps and the other to determine if the track is empty.

-Inverted lids are easily detected by the error lids sensor. Error caps remover and bottle sensor work together to achieve a satisfactory capping effect.

-By changing the moving speed of bottles at its position, the bottle separator will separate them from one another. In most cases, one separator is required for round bottles, and two separators are required for square bottles.


-The bottle conveyor and cap feeder have a maximum speed of 100 bpm, allowing the machine to run at a high speed to accommodate varied packaging lines.

-Three pairs of wheel twist caps off rapidly; the first pair can be reversed to swiftly place caps in the correct position.


-Adjust the height of the entire capping system with just one button.

-Adjust the width of the bottle capping track with the wheels.

-Cap feeder, bottle conveyor, capping wheels, and bottle separator can all be switched to open, close, or change speed.

-Flip the switch to change the speed of each set of capping wheels.

Easy to operate

-The use of a PLC and a touch screen control system with a simple operating program makes work easier and more efficient.

-The emergency stop button allows the machine to be stopped immediately in an emergency, keeping the operator safe.
