Pneumatic Bucket Capping Machine | 20-Liter Bucket Capper

The pneumatic bucket capping machine is designed for pressing and sealing the lids of open-top buckets and drums using a press-fit method. In this machine, after placing the lid on the bucket, the pneumatic system applies uniform pressure from above to press the lid onto the bucket's opening, ensuring it is fully seated.

This machine can operate in both semi-automatic and automatic modes. Thanks to its roller conveyor, it can be used independently or installed as part of filling and other packaging line equipment.

The machine's capacity is up to 10 buckets per minute, making it suitable for production lines that require fast, uniform, and repeatable capping.

Bucket Holder System During Capping

One of the important features of this machine is its bucket holder system. When the press plate descends and pressure is applied to seat the lid, the bucket must be in the correct and stable position. The bucket holder secures the bucket in place during capping to ensure stable pressing and prevent the bucket from moving under pressure.

This feature is particularly important for plastic buckets and containers that require relatively high pressure to fully seat the lid.

Semi-Automatic Operation with Pedal

In semi-automatic mode, the operator places the lid on the bucket and guides the bucket to the pressing station. Then, by pressing the pedal, the capping cycle begins.

The bucket holder keeps the bucket in the correct position, and the pneumatic jack moves the press plate downward. With pressure applied, the lid is seated on the bucket's opening, and after the cycle is complete, the press plate returns to its initial position.

Using the pedal allows the operator's hands to be free for guiding and controlling the bucket.

Automatic Operation with Bucket Detection Sensor

The machine can also be operated automatically. In this mode, a sensor detects the presence of the bucket at the capping station. Once the bucket is correctly positioned, the machine automatically executes the pressing cycle, seating the lid with pneumatic pressure.

After the operation is complete, the bucket can be transferred to the next stage of the production line.

Thus, the machine can be used as part of an automatic bucket filling and packaging line.

Adjustable Incline Roller Conveyor

A stainless steel roller conveyor is used underneath the machine for bucket transfer. The incline of the machine is adjustable, and when used independently, the rollers can be set to an appropriate incline so that buckets move using gravity without the need for a conveyor motor.

This design not only reduces power consumption but also simplifies the machine's structure and makes maintenance easier.

In similar industrial models, using a roller conveyor for transferring buckets to the press unit is a common method.

Capability to Connect to Filling and Packaging Line

This machine is not limited to independent use and can be installed in automatic production lines.

Upon request, the height and base of the machine can be made to match the height of the production line conveyor to align the machine's input and output with the equipment before and after it.

For example, a line can be designed as follows:

Bucket Filling Machine → Bucket Transfer → Lid Placement → Pneumatic Bucket Capping Machine → Labeling Machine → Product Exit

Therefore, the machine can be placed between existing equipment in a packaging line and used as a capping station.

Full Construction from Stainless Steel 304

The body, frame, and main components of the machine are made from stainless steel 304.

The use of stainless steel 304 provides a durable, washable surface suitable for industrial environments and food industry lines, allowing the machine to be used for a wide range of products.

The machine can be used in packaging lines for products such as foodstuffs, detergents, chemicals, oils, greases, paints, and other products offered in press-fit lid buckets.

For the final selection of the compressor, it is advisable to consider not only the tank volume but also the air flow rate of the compressor in relation to the diameter and stroke of the jack and the number of cycles per minute; merely having a 50-liter tank does not guarantee sufficient air supply.

Application of the Machine

The pneumatic bucket capper is suitable for units that package their products in plastic buckets with press-fit lids.

Common applications include packaging of paints and industrial coatings, adhesives, resins, detergents, oils and lubricants, greases, chemicals, and some food products. Similar industrial lid press machines are also offered for plastic buckets and applications in food, paint, and chemical industries.

Customizability of the Machine

Depending on the bucket dimensions and the customer's production line structure, the machine can be customized. The height of the machine, roller conveyor dimensions, base height, bucket entry and exit method, and control system can be designed to fit the production line.

For installing the machine in automatic lines, it is possible to synchronize the machine's input and output with the filling machine, conveyor, and subsequent packaging equipment.
