4.What are the main components of granule packaging machine?

As a matter of fact,the structures of fully automatic granule packaging machine and semi automatic granule packaging machine are different,their main components are also not the same.

Main Components of Fully Automatic Granule Packaging Machine

Automatic Granule Packaging Machine

As the picture shows,the main components of fully automatic granule packaging machine are multi head weigher,Z-type conveyor,vibrating feeding machine,working platform,packing machine,output conveyor and PLC touch screen.The PLC touch screen is to set up the parameters of the machine.

Vibrating feeding machine is to feed the granular products,multi head weigher is to measure and weight the volume of granular products,the packing machine is to complete the whole packing process,and the output conveyor is to deliver the finished products.

Main Components of Semi Automatic Granule Packaging Machine

Main Components of Semi Automatic Granule Packaging Machine

The semi automatic granule packaging machine consists of hopper,PLC touch screen,film reel,bag maker,sealing device,cutting device and conveyor.The hopper is the feeding device of the machine,and the purpose of PLC touch screen is to control the whole machine,film reel is to fix the packaging film.
And the bag maker,sealing device,cutting device,the function these components is to pack the granular products better.The conveyor is to deliver the finished products.

5.What is the working process of granule packaging machine?

In general,the working process of granule packaging machine is not complex,it contains bag making,bottom sealing,products filling,top sealing,cutting and discharging.

working process

Bag Making

The packaging material is rolled on the film reel,when the machine is turn on,the packaging material is pulled and folded into pouches according to requirements.

Vertical Sealing

In this step,the materials which are folded into pouches are sealed by heat sealing,the side of the pouches are sealed.

Bottom Sealing

When the side of the pouch is sealed,the next step is to seal the bottom of it,so that it can pack granular products.

Products Filling

The products enters the machine by hopper,and flow down,then be filled into the formed pouches.

Top Sealing

After the products are packed in the pouches,this is the last sealing step,to seal the top of pouches,at that moment,the packaging is forms,can pack the products well,without any leakage.

Cutting and Discharging

Although the pouches are formed,they are still connected cause they are made from a complete packaging film,so next step is to cut the joint to separate each pouches,and then the finished products are delivered by conveyor to be discharged,until now the working process is finished.

6.What are the types of granule packaging machines?

According to automation degree,there are three common types of granule packaging machines available on the market,they are manual granule packaging machine,semi automatic granule packaging machine and fully automatic granule packaging machine.

Manual Granule Packaging Machine

Manual Granule Packaging Machine

Manual granule packaging machine,as the name suggests,this is a machine which need manual operations,as the picture shows,the structure of manual granule packaging machine is a little simple,you need to complete the bag making,filling,sealing and cutting operations by yourself,as a result,the packaging speed is slow.

And because the machine is manual,the function is also more simple than the automatic ones. Therefore,the manual granule packaging machines are more suitable for small scale production,for example,for family usage.

Semi Automatic Granule Packaging Machine

Semi Automatic Granule Packaging Machine

Semi automatic granule packaging machine is equipped with a PLC touch screen,you can turn on and turn off the machine and set up parameters by this screen,this machine is much more convenient than the manual one.

But,although the machine has a certain degree of automation,it also need manual intervention during the working process.The semi automatic granule packaging machine can pack 45-60 pouches per minute,the packaging speed is quite faster than the manual one,it is more suitable for medium scale production.

Fully Automatic Granule Packaging Machine

Fully Automatic Granule Packaging Machine

As you can see that the fully automatic granule packaging machine is a large size machinery,it is quite advanced and smart,like semi automatic granule packaging machine,the fully automatic one also adopts PLC touch screen.
The machine is so large that it can pack all kinds of granular products which have different requirements for pouches such as size and thickness.Also,the production capacity of this machine is pretty high,as a result,it is used for large scale production demand,mostly used for industrial applications.

7.What are the differences between fully automatic & semi automatic granule packaging machine?

In this part,you will learn the differences between fully automatic granule packaging machine and semi automatic granule packaging machine,and know which one is more suitable for you.

fully automatic

Size:It is obvious that the fully automatic granule packaging machine is much larger than the semi automatic one because it is more suitable for large scale production.
The fully automatic granule packaging machine need to be put in workshop which has large space while semi automatic granule packaging machine can be used in normal room.

Production Capacity:The production capacity of fully automatic granule packaging machine is higher than that of semi automatic granule packaging machine because its automation degree is high,it doesn’t need manual intervention,so its production speed is faster.

Cost:It is evident that the cost of fully automatic granule packaging machine is higher than that of semi automatic granule packaging machine because it is more advanced.
