4.What are the basic components of a liquid milk 4 side sealing machine?

There are several components in a liquid milk 4 side sealing machine. These components work together to form quality sachets and stick packs. Some models may have additional components but the major parts are the same in all models.

The basic components you will find in a liquid milk 4 side sealing machine are listed below.

Components of Multi lane Liquid Milk 4 Side Sealing Machine

Hopper

A hopper is an inverted container that holds the bulk material (a significant amount) before directing it to process. It can be of various shapes, such as rectangular, pyramidal, or conical. The quantity of material it can hold depends on its capacity, which can be varied with different models. The rate of material supply can be regulated in certain models.

Film Pulling Mechanism

The film-pulling mechanism involves:

The film frame – that holds the large film roll such that it can unwind smoothly.

The dancing rollers – these are responsible for unwinding the film roll, and facilitating its feed to the machine.

Bag Maker

A bag maker section contains a forming/shaping tube responsible for the fabrication of sachets and stick packs of the desired dimensions from the supplied film. The film material get folded around the forming tube and sealed to form a packet.

Automatic Sealing

The sealing station comprises vertical sealing bars and horizontal sealing clamps. They are responsible for the effective heat-sealing of the sachets (forming stage and after filling) and stick packs.

Touch Screen

The screen panel aids in the spot-on monitoring and regulation of the process parameters. The device is instructed for the process through the touch screen.

Discharge Conveyor

The discharge chute/conveyor facilitates the exit of the finished packets from the machine.

Host Electrical Configuration

It consists of the touch screen and the “power switch” that connects the device to the power supply needed to run the machine. It can also contain the “emergency stop button”, which causes immediate cessation of the process in case of an incident.

5.How does a liquid milk 4 side sealing machine work?

Working on a Liquid Milk 4 Side Sealing Machine

The liquid milk 4 side sealing machine can have several lanes (1-12) that work in the same fashion. The working of this device includes a few basic steps:

Steps of the Working Process

Liquid Material Loading

The process starts by loading a significant amount of product into the hopper. The dimensions of the hopper will determine the volume to be loaded. The loading is done manually or using an automatic mechanism.

Film Feeding and Unwinding

Another beginning step is placing the film roll on the film frame and unwinding it, which will carry the product. A reel will grip the film material as it unfolds utilizing a cross-seal clamp, keeping it moving.

Printing

It is an optional step and can be done by certain variants. The device with a date imprinting system will position the date imprint on the packages via a registration roller.

Film Slitting

The film is headed towards the slitting section. In this step, the film is cut down into strips. The number of strips produced relies on the number of lanes in the device. The film is cut down via cutting blades while still in tension.

Formation of Packs

After slitting, the strips will be directed to the shaping tubes. Only a single strip can pass a lane. The strips form a pouch by such folding that the edges join each other. The tubes can be adjusted to produce specific edge seals (lap/fin).

Filling and Sealing

In this step, various heated seal bars guide toward the tube, creating a vertical seal. After this, lateral sealing clamps will form a top-edge seal on one pack and a bottom-edge seal on another pack.

After that, the liquid material will enter the pouch. For accurate filling, multiple filling techniques are utilized, such as piston fillers or volumetric fillers.

Discharge of Finished Products

After filling, blades cut down the pack which are directed towards the outlet and get discharged.

6.How do you classify a liquid milk 4 side sealing machine?

There are various models of the liquid milk 4 side sealing machine available designed based on different requirements. Each of them has unique characteristics and features. It can be classified based on orientation, operating principles, and filling mechanisms installed.

Classification of Liquid Milk 4 side sealing Machine

Classification Based on Orientation

Vertical Form Fill Seal (VFFS) Liquid Milk 4 Side Sealing Machine

Vertical Form Fill Seal (VFFS) Liquid Milk 4 Side Sealing Machine

In the vertical form fill seal (VFFS) liquid milk 4 side sealing machine the materials are processed downwards and the finished products are expelled from the bottom. The device forms, fills and seals the packages in the vertical configuration.
