Shanghai Tops Group has developed a linear screw capping machine with outstanding screw cap performance and easy operation. Because it pushes the caps more securely and causes less damage to the lids, this machine is more efficient than intermittent capping. The fuselage body is composed of stainless steel 304 material, which fulfills GMP criteria.

It is used in various screw cap bottle shapes in the food, pharmaceutical, chemical, and other industries.

Linear Screw Capping Machine Details

One button

A single button adjusts the height of the entire capping device to accommodate different bottle heights.


Wheels to vary the width of the bottle capping track to accommodate different bottle diameters.

Four switches

Four switches regulate the width of each pair of white capping wheels, allowing you to fine-tune the degree of tightness.

Switch to open

Switch to open, close, and adjust the speed of the cap feeder, bottle conveyor, capping wheels, and bottle separator.

PLC&touch screen

The PLC and touch screen control of the linear screw capping machine are easy to operate.

Emergency button

The emergency stop button for the machine is for safety and is easy to operate.


The cap automatic control places the cap horizontally at a 30° angle. The bottle separator splits 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.

Forming a Packing Production Line

The linear screw capping machine can be combined with filling and labeling equipment to create a packing line.

A bottle unscrambler + auger filler + linear screw capping machine + foil sealing machine + labeling machine are a few examples.

Linear Screw Capping Machine Test

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

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

1. What Is The Use Of The Machine?

The linear screw capping machine is used to screw caps on bottles automatically. This is designed for use in an automated packing line. This machine is a continuous capping machine, not an intermittent capping machine. This machine is more efficient than intermittent capping because it securely presses the lids and causes less damage to the lids. It’s now widely used in the food, pharmaceutical,  chemical industries and more.

2.What is the Function of Each Part of Linear Screw 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.

3. Is The Machine Customized?

Yes, it can be customized according to the customer’s requirements. It is designed for use in an automated packing line and can add other processing equipment.

There are options:

Packing line 1

The linear screw capping machine can be integrated with filling and labeling machinery to create a packing line. Some examples are: bottle unscrambler + auger filler + linear screw  capping machine + foil sealing machine.

Packing line 2

The linear screw capping machine can be connected with filling and labeling equipment to produce a packing line. Just a few examples include a bottle unscrambler + auger filler + linear screw capping machine + foil sealing machine + labeling machine.

4. Is An Engineer Available To Serve Overseas?

Yes, but the travel fee is your responsibility.

In order to save your cost, we will send you a video of full details of the machine installation and assist you till the end.

5. How can we Make Sure About the Machine Quality After Placing the Order?

Before delivery, we will send you the pictures and videos for you to check the machine quality. And also you can arrange for quality checking by yourself or by your contacts in China.
