Parts Of 4 Side Sealing Packaging Machines

The machine has a unique design with automatic filling and sealing. Let’s explore the main components of the 4 side seal packaging machine:

parts of 4 side seal packaging machine

a. Feeder System: Supplies the packaging material, and only feeds out enough material for one pouch at a time.

By doing so, the feeder ensures that you do not have too much left over after sealing.

b. Rollers: Feed material through the machine and then wrap it around the product being packaged for proper sealing on all four sides.

c. Filling Head: The filling head is located at the top of the conveyor belt and injects product into the pouch.

It includes valves and cylinders used to fill products into the sachet.

d. Heat Sealing Head: Seals the material using heat so that it creates a tight seal around all four sides of the product being packaged.

There are two heat sealing heads in 4 side sealing machine:

  • End Sealing Head: Used for top and bottom sealing of pouches and bags with a heat-sensitive adhesive.

There are different types of sealing heads like hot melt or hot air sealing head to meet different packaging requirements.

  • Side Sealing Head: Helps in sealing the sachets longitudinally using heat or pressure sealing method.

e. Cutting Head: Uses blades that cut pouches into individual units when needed.

Also, it cuts off any excess material that might be left over after sealing the side flaps together.

f. Conveyor Belt: It is used to move the product from one location to another.

Filling Mechanism In 4 Side Seal Packaging Machine

The filling mechanism is the most important part of any packaging machine.

It has to be designed in such a way that the product can be filled properly and uniformly into the package.

There are different types of filling mechanisms and we will discuss them in detail as follows:

Pneumatic Filler

Here, there is a pump attached with the filler which pushes the product into the package.

The product is injected via a nozzle attached at the end of filler tube.

These are most commonly used for liquid products like shampoo, milk, juices among others. Pneumatic filling is not suitable for powders because it may clog or block filler tubes if not cleaned properly after every cycle.

Consequently, this can lead to poor quality products.

Positive Displacement Pumps

The pump employs a simple principle of pumping liquid through a pipe by creating a vacuum at one end that draws in liquid.

Similarly, it creates pressure at the other end that propels the liquid out of the pipe.

Piston in this machine moves forward and backward while pushing a volume of liquid out of its chamber at each stroke.

During selection, the most common types of positive displacement pumps are centrifugal, volute rotary screw and vane pumps.

Each type has different advantages over others depending on their purpose, such as cost or efficiency.

Gravity Filling Mechanism

The gravity-fed filling mechanism works by using gravity to transport the product from the hopper to the filling head.

This type of mechanism has excellent accuracy but it can be slow due to its reliance on gravity to move the product through it.

Therefore, it is suitable for low viscous products like viscous liquids, powders, granules or tablets.

Sealing Mechanisms In 4 Side Seal Packaging Machine

There are a number of different ways of sealing in 4 side seal packaging machine, depending on the packaging material being used:

Heat Sealing

Heat sealers use heat to form a bond between two pieces of material.

The system applies an adhesive tape or glue on one side of the sealer before placing it on the packaging material with no adhesive.

The glue or tape melts when heated, bonding both sides together with an airtight seal.

Some heat sealers can be used with different types of materials such as paper and plastic film (PP). Others may only be used with one type such as polypropylene (PP) film only or polyethylene (PE) film only.

Cold Sealing

These type of sealing mechanism also use heat. However, instead they use cold temperatures to form an airtight seal without melting down completely like in hot sealing.

Mechanical Sealing

In mechanical sealing the seal is formed by means of an elastic material or a rubber.

The material is pressed against the sides of the package by means of a moving blade or roller.

A variation on this type of seal is called “mechanical press” and uses pressure to form the seal rather than a sharp edge.

Vacuum Sealing

Vacuum sealing machines use vacuum to pull two pieces together and form a seal around them.

The sealer head applies heat and/or pressure simultaneously while they are held tightly together against opposing surfaces inside an airtight chamber.

How 4 Side Seal Packaging Machine Works

Operation of 4 side seal packing machine involve the following main steps:

Step One: Film Roll Feeding

The film is fed to the front and back of the machine via tension control rollers. If different films are utilized, two rolls will be supplied.

If the same film is used on both sides, it is common to supply one, wide roll of film. As the film comes off the roll, it is cut in half.

The two halves of the film are guided to the machine’s front and rear.

Step two: Sealing

Subsequently, the films are joined and passed through a pair of rollers that form the longitudinal, lengthwise seal between the pouches.

To compensate for any minor misalignments, a small amount of material is usually trimmed from the joined film’s outer edges.

The cross seal is formed by a second sealing roll below, which seals the bottom of the current pouch and the top of the preceding pouch.

Rather than a flat surface, these rolls are typically designed with cavities.

The design allows them to conform to the shape of the product or to make room for it.

Step Three: Product Feeding

The pouch is now formed on three sides, and you can introduce the product.

To dispense the product into the pouch, you can use various types filling pumps (liquids) or feeders (solid).

Nitrogen or another gas can be injected at this point if necessary.

It is critical to avoid getting powder or liquid on the seal area, as this will interfere with proper sealing.

Step Four: Cutting

As the pouches move through the equipment, they are cut longitudinally into strips. Using a cross cutter, the strips are slit into separate pouches.

Step Five: Printing:

Here, the 4 side seal packaging machine prints data matrix text and barcode using thermos transfer, laser or ink.

Step Six: Inspection

Integrated vision inspection system of the packaging verifies the OCR print, product presence and position, with any non-conforming packs being rejected automatically.

Step Seven: Discharge

Finally, the 4 side sealing packing machine discharges the conforming packs for onward manual or automatic processing.

Troubleshooting 4 Side Seal Packaging Machine

The following are troubleshooting tips for 4 side seal packing machine that you can follow in case you encounter an issue:

i. Sealer not sealing properly or sealing at all: Check if the seal bar is lined up with the seal plate and make sure the pinch wheel is not under any pressure.

ii. No power: Check if the power cord has been plugged in and make sure there is no obstruction in between that could cause a short circuit.

iii. Sealing bar does not move up and down: Check if the drive belt has been correctly placed on top of the motor pulley.

If it has been removed from its position, then you need to reattach it before trying again.

iv. Machine keeps breaking down or shutting down automatically: This happens when too much pressure is being applied by too many items being packed per cycle.

v. Machine keeps jamming and not working at all or not sealing properly: The most common cause is that there are no products left in the feeder.

Make sure there are enough products in the feeder system before starting up again after a jam.

If the problems persist, then you will probably have to stop and clear out any remaining product manually before restarting again.
