Can seaming machines have been around for decades, and there’s no arguing the fact that they have become a necessary tool and component for food and beverage production processes. With a can seamer, your process of production and your production line can move faster and quicker, and you can also benefit from a more efficient process and produce more of your products to meet consumer demands. But it also pays to choose your can seaming machine in the proper way; this goes with knowing about what it consists of and how all these parts work. If you want to select your can seamer correctly, here’s your best guide to the most integral parts of a can seaming machine.
- The chuck or seaming head
The seaming head or chuck purposely holds the tin together along with the turntable of the seamer whilst the double seaming process is ongoing. It also serves to protect the tin from the pressure of the roller operation. The dimensions of the chuck or seaming head will depend on the diameter of the can, so you would need different seaming heads or chucks for different diameters.
- The base plate or turntable
The base plate or turntable is also called the compression plate, and it is a disc running on springs that can spin and provide support to the body of the tin whilst it is sealed. It is designed to centre the body of the tin in the right position as it brings the spring’s pressure to the container. The shape of the compression plate will also depend on the tin’s shape so it can be inserted or placed correctly.
- The seamer rollers
A can seamer will often have two rollers that are concave, and these can create double seaming. The machine’s speed will determine if it will have one set or several sets of rollers. The profile of the first roller with regards to the seamer head is crucial in producing a good and reliable seam, and a lot of problems with double seaming can arise due to the incorrect position of the first roller.
- The vacuum room and sealing chamber
The can seaming machine performs the process of sealing in a sealing chamber as it has to remove the oxygen from the tin before it is sealed. The oxygen removal occurs in the vacuum room under pressure, and with this, you can maintain the integrity and quality of your product.
- The ejector, feeder caps, and transport
The ejector is a rod-like object with a small disc, and this emerges at the centre of the seamer head and then moves in a vertical manner. It also allows for the correct placement of and positioning of the lid on the tin. Feeder caps are often seen in automatic machines, and they can get a specific lid from the pile and then transport this to the sealing station prior to the process of sealing. The transport feature, on the other hand, is the way through which the machine transmits the filled tins into the machine. The most common transport features include conveyors, which can move the containers continuously from one particular station to the next station.
