🔵 Piston Cylinder

Enclosing a piston mechanism that moves forward and backwards, the piston-cylinder applies pressures to liquid goods to make them more fluid.

🔵 Hopper

This bulk storage unit sits above the packaging machine. This hopper, which may be square or circular, distributes the correct product amount to the filler.

🔵 Stick Pack Forming Station

Here, using vertical sealers and making tubes, the strips turn into stick packs.

🔵 Horizontal Sealer

This component joins the stick pack’s upper and lower halves using heat, pressure, or ultrasonic waves.

🔵 Cutter

At its base, the machine has cutting blades that separate the stick packs by trimming their edges.

🔵 Film Unwinding Disk

The unwinding disk undoes the knots in the packing film as it travels over the roller on the rolling stock.

The machine is mobile and stable thanks to the caster wheels. They keep the equipment steady and support its weight.

What are the classifications of stick packaging machines?

The degree of automation, the quantity of lanes, and the forms of motion are the criteria that classify the machine into several groups. Here is the summary of its classification:

(A) Degree of Automation

🔵 Semi-Automatic 

It is perfect for small and medium-sized production as it is compact and easy. The PLC allows for simple control of the machine’s operations. Autonomy occurs by the filling, shaping, and sealing processes of stick packs.

Still, the workers must physically load and unload the machine with raw materials and stick packs, making it labor-intensive equipment. Because it only has one or two lanes, its output is minimal.

🔵 Automatic

This machine has four to twenty lanes, making it both quick and efficient. With the machine packing process, the loading of materials and forming stick packs are entirely automatic. The equipment can fill, seal, and unload stick packs automatically, eliminating the need for an operator. As a result of its enhanced efficiency, it is a crucial part of large-scale businesses.

(B) By Lane Number

🔵 Single-Lane Stick Pack Machine

Its moniker comes from the fact that it is built around a single lane. It only takes one cycle to create and fill a single stick pack, so its production volume is minimal. This unit is often in small and medium-sized businesses.

The major benefit of this machine is its small size and compact design, which makes it easier to clean, maintain, dismantle, and reassemble.

🔵 Multilane Packing Machine

A machine of this sort may increase the speed of up to twenty lanes. It can handle many stick packs in a single cycle since it has multiple lanes. Industries rely on this equipment for efficient packing of items because of its speed.

The fill, seal, and stick-forming lanes are all in sync with each other. Its main disadvantage is the amount of area it requires for operation due to the existence of multiple lanes.

(C) Motion Type-Wise

🔵 Intermittent-Motion 

This kind of machine has a lower processing capacity. This is because, as the name implies, it operates intermittently, pausing to create, load, and seal a stick pack.

Equipment that can start and stop is another name for it. When it comes to manufacturing, the intermittent-motion stick packaging machine is the way to go for fragile products that need precision filling.

🔵 Continuous-Motion 

As it produces stick packs continuously, this machine is an integral part of large-scale production and has a high capacity for processing. A continuous-motion stick pack machine does not pause between cycles; it operates nonstop.

Perfect for moving large or heavy objects, this adaptable machine can handle a variety of tasks. Faster filling of strong items is where it shines.

How Does the Stick Packing Machine Work?

The many mechanical components of this machine work in tandem to guarantee that the filling, sealing, and machine-forming processes go off without a hitch. Various operational procedures are detailed below:

🔵 Product Material Feeding

The big square or circular hopper, often at the machine’s top, is where you put your product material. This is for the product-feeding process to go smoothly. Infeed tanks distribute products within the hopper on occasion.

🔵 Film Load and Unwind

You or robotic arms load the rolling stock with a massive film roll. The film is wound into narrow strips using a film-unwinding disk, which then transfers the film to blades that cut it into tiny pieces. Here, the number of strips corresponds to the stick pack machine’s lane count.

🔵 Forming Stick Packs 

Following their transfer to the proper forming tube, the film strips are double-wrapped by the forming collars of the conical-shaped forming stations to create the stick packs. The horizontal sealer covers the bottom seam of the tubular pouch, while the vertical sealer uses either high heat or ultrasonic waves to fuse the side seams. The use of these sealers causes the formation of stick packs.

🔵 Filling Stick Packs 

When a stick pack is ready, the filling systems are activated to fill the pack with items. The product is slowly distributed into the stick packs thanks to the filling station’s rotating auger and volumetric cup, piston action, and vibratory plate vibration.

🔵 Sealing and Cutting of Stick Packs

After filling the product, we will then proceed to the next stage of operation: cutting and sealing. The heated bars running horizontally seal the tops of the stick packs, and the sharp blades in the middle of the bars serve to divide any two adjacent packs.

What are the Filling Systems in the Stick Packaging Machine?

The equipment has a variety of filling systems that are designed to work with particular products. They are:

🔵 Auger Filler

Accurate filling devices are auger fillers. It has a dispensing nozzle, screws, a rotating plate, an auger shaft, and a funnel. It reduces product contamination by its closed design. Granules and gritty powders often make use of it. The motors turn the auger shaft, which then mete out the goods from the nozzles.

🔵 Piston Filler

The parts that make it up include a piston, hopper, cylinder, and nozzles for filling. A piston’s back-and-forth motion inside the cylinder is crucial for transporting the gels and liquids from the hopper to the cylinder and following that to the stick pack. Because of its pinpoint accuracy, it is the method of choice for filling thick creams and pastes.

🔵 Volumetric Cup Filler

Filling stick packs with grains, salt, coffee grinds, and other granular, powdered, and pellet products. Rotating plates hold cups and a preset syringe. Initially, the syringe checks the cup filling capacity, then dispenses it into the cup and loads the stick packaging.

🔵 Multi-head Filler

Fill stick packs with candies, snacks, and other tiny items. In order to fill stick packs, its many heads coordinate their movements. High processivity and accuracy are hallmarks of multi-head fillers.

🔵 Pump Filler

Filling free-flowing, non-viscous liquids into stick packs is the usual function of this filler. The filling nozzle precisely dispenses a set quantity of liquid while the pump, like a gear or lobe, rotates. You can liquid products to sticks using its filling nozzles.

What are the Different Seal Patterns a Stick Packing Machine creates?

Each stick pack has its unique pattern of seals. This is because you may set up the stick pack machine to accept various patterns of seals, such as:

🔵 Easy to Open Seals
