4.What Are the Working Principles of Can Sealing Machine?

working-principle-of-can-sealing

Even though, can sealing machine has various types, the working principle of all these is generally the same.

The can is brought to the machine where the sealing process will take place. Pressure is applied to the body of the can which is then moved to the seamer base plate. Here, the seamer head orients the lid over the mouth of the can.

As soon as the lid comes aligns with the body of the can, the first roller attaches the flange of the lid on the sides of the can. The roller keeps on applying force on the lid till it curves nicely around the can, forming the first hook.

Next, the second roller forms a second sealing layer by applying considerable amount of pressure to push the two edges toward each other. As a result, a hermetic seal is formed which cannot be opened unless a powerful force is applied to open it.

This is how the sealing process of the can takes place, after which, the cans can easily be shipped for sale.

5. What Are the Components of Can Sealing Machine?

components-of-can-sealing-machine

This machine has various components which have their own specific function. Let us take a look at each of these parts.

Seamer head (Chuck): this is one of the main parts which is responsible for holding the can when it is being sealed during the double sealing process. It also protects the cans and tins from the pressure of seaming rollers which would form dents on them if not monitored. Seamer head is also known as chuck.

Sealing chamber: this is the main room where the can is placed inside and all the oxygen is sucked out to form a vacuum like environment inside the chamber. After that, the can is sealed by closing it with a lid.

Seaming rollers: can sealing machines are provided with two concave shaped seaming rollers.

One of the rollers is responsible for handling the body of the tin or can whilst the other roller is responsible for handling the lid. The setting up of these rollers is technical and would require a trained worker who would be able to set them up correctly.

Seamer base plate:this holding base for the can provides support to the can when it is being closed with a lid.

Conveyor belt: this belt runs automatically and is responsible for transporting the cans from one part of the machine to the other.

Ejector: this part, as the name suggests is used to eject the filled cans to the other part of the production line after the sealing process has been done. It also helps in placing the lid on top of the can or lid. It is shaped like a rod which has a small disc situated at one of its end.

This disc comes from the chuck. The speed at which the ejection process takes place needs to be carefully monitored since it can damage the cans if not ejected properly.

Feeder caps: these caps are responsible for supplying the lids to the can sealing machine where they can be used to seal the tins. They work automatically by picking up the lids from their respective place and transporting them to the machine where they are used for sealing purposes.

Electrical component: this usually contains an electric box which consists of all the electrical components needed to operate the machine.

Touch screen: touch screen consists of all the parameters of this process which can be monitored. This screen is monitored by an operator who makes adjustment to the sealing process as required.

6.What Are the Types of Can Sealing Machine?

There are several types of this machine. Each have their own unique features, advantages and disadvantages.

Can sealing machine are broadly classified into two groups:

  • Based On Automation

Based on automation, this machine is divided into

Automatic Can Sealing Machine

Automatic Can-Sealing-Machine

This type of machine is used to make a hermetic seal around the body of the can in an automatic way. It is capable of forming double and triple seal. The lid is made of tin plated steel whereas the boy of the tin or can is made of aluminum, stainless steel or glass.

Automatic can sealing machine are provided with many seamer heads or chuck. This number can range from 4, 6 or 12. As the number of seamer heads would increase, the capability of sealing tin cans would increase too.

This would result in the increased sealing capacity of the machine and would be able to package high volume of products in lesser time, earning more profits. Moreover, this machine greatly reduces labor costs since the whole process works pretty much on its own and only requires a worker to monitor it.

Semi-automatic Can Sealing Machine

Semi-automatic-can-sealing-machine

This type of machine is almost exactly like automatic can sealing machine with the exception that a worker is required to initiate the sealing process. Moreover it can only seal one tin at a time. Thus it is ideal for small scale businesses or factories where there is low volume production.

This machines’ greatest feature is that it is way cheaper than automatic can-sealing machines, making it affordable for a greater number of people who want to install it in their small factories. Plus, it gives accurate results since the process is not completely manually operated.

Manual Can Sealing Machine

Manual-can-sealing-machine

This type of can sealing machine as the name suggests is used to seal tins or cans manually. It consists of a long handle to hold the sealer and a circular disc that seals the lid. it is the cheapest among all of them since the whole process has to be done manually. It is safe, convenient, and easy to use and is ideal for use in homes.

  • Based On Machine Design

Rotary Can Sealing Machine

Rotary-can-sealing-machine

In this type of machine, when the sealing process is taking place, the can is made to rotate on its own axis. It is also provided with 18 seamer heads. Thus this type is suitable to integrate in an automatic can sealing machine which needs to seal thousands of cans in a single day, making it ideal for large-scale operations.

Rotary can seal machine is used in those industries where the customer doesn’t have to worry about dents forming in cans or spilling of the contents inside it. It is ideal for sealing round-shaped cans.

Non-rotary Can Sealing Machine

Non-rotary-can-sealing-machine

In this type of machine, when the sealing process is taking place, the can remains still and doesn’t rotate on its axis. It is ideal to use in industries where the cans are filled with liquid products and the contents inside need to be handled carefully to prevent their spillage. It is used to seal oval and rectangular-shaped cans.

Thus it is much safer to use and the customer doesn’t have to worry about the cans getting damaged or the contents leaking from the inside.

7. Can Sealing Machine VS Bag Sealing Machine

Cans

Even though, the main purpose of both these machines is to seal products in a bag or a can, there are a few differences which make them unique in their own way.

Bag sealing machine is mainly dependent on the heating process to seal bags or pouches. With the help of a power supply, heat is produced at the top and bottom of heating blocks which then seals off the bag with the help of rollers.

Bags

On the other hand, the can sealing machine uses force or pressure on the body of the can after which the seamer head aligns the lid with the body of the can. Next, the seaming rollers apply pressure over the lid till it attaches to the can and forms an airtight seal.

When comparing their cost price, can sealing machine is relatively more expensive than bag sealing machine. In terms of space requirements, can sealing machine generally takes more space than bag sealing machine.

8. Automatic Can Sealing Machine VS Semi-automatic Can Sealing Machine

Cans-1

Although this two machines have the same purpose and seal cans and tins exactly the same way, they have a few differences. Automatic can sealing machine seals cans or tins automatically that is, it works completely on its own without any person’s involvement.

The worker only has to monitor the whole process with the help of control panel. Whereas in a semi-automatic can sealing machine, the process has to be initiated by a worker. He needs to put the cans inside to begin the process.

In terms of space requirements, an automatic can sealing machine usually takes more space than a semi-automatic sealing machine. Moreover, automatic can sealing machine is more expensive than the latter since it is more efficient, high speed and has the ability to seal more tins at a time than a semi-automatic can sealing machine.

This makes automatic can sealing machine more ideal for large-scale industries whereas semi-automatic can sealing machine is more suitable for small-scale businesses and factories.

9. What Is the Maintenance of Can Sealing Machine?
