Have you noticed how the various liquid pastes or snack powders we use in our daily lives, such as bottled water, cosmetic samples, potato chips and coffee powder, are packaged? Vertical packaging machines are divided into liquid packaging machines, paste packaging machines, powder packaging machines, multi-functional packaging machines, etc. Its appearance greatly saves time and labor costs. In the following article, I will introduce to you in detail the working principle of vertical packaging machines.

From the external structure, the packaging machine looks upright as a whole. The main packaging materials are liquids, particles, powders, etc. for quantitative packaging. It is usually composed of a material supply device, a material weighing device, a bag-making and sealing device, a cutting device, and a control device. The function of the material supply device is to place the material and wait for the machine's operating instructions to unload the material. The function of the bag-making device is to package the material. The sealing device refers to the mechanical sealing of the bag containing the material. The function of the cutting device is to cut the continuously packaged bags into small bags of finished products. The control system acts like a big housekeeper, controlling the operation of the entire machine and the distribution of instructions.

Material supply device

1. Machine hopper - packaging machine storage bin

The material supply device of the vertical packaging machine is the first step in packaging. The hopper of the machine will be customized according to the size and weight of the material you want to package. The inside of the hopper will also be equipped with a stirrer according to the characteristics of the material. If the material is powdery and easy to stick to the surface of the machine, you will be equipped with a stirring bucket to ensure the accuracy of material feeding. If the material is a paste that is easy to solidify, the hopper can be customized with an insulation bucket and a stirrer for you to keep the material at a constant temperature and stir to help the material mix better. This ensures the supply of materials for you to wait for the next packaging step.

2. Feeding of the machine - Transportation channel of the packaging machine

When the material is ready, the machine receives the instruction and transports the material to the unloading place through the feeder. Generally speaking, packaging machinery includes screw conveyor, vibrating feeder, belt conveyor, etc. Screw conveyor is suitable for granular or powder materials, such as potato chips and biscuits. Vibrating feeder is generally widely used for smaller granules or powders, and the purpose of moving the material forward is achieved through the vibration of the machine, such as white sugar and coffee powder. Belt conveyor is mainly used for larger block or large granular materials, such as grains.

Material weighing device

There is a weighing hopper inside the machine. After you place the material, it must be accurately weighed in the weighing hopper before the next package can be made. This part controls the accuracy of the entire packaging bag. After you set the weight of the package, the feeding system of the machine will weigh the set weight to the weighing hopper and then put the material into the bag to wait for sealing. It accurately controls the weight of each finished product package, avoids the waste and inaccuracy of manual operation, and reduces costs for you. It is an indispensable part of the vertical packaging machine and plays an important role in ensuring production efficiency and reducing costs.

Bag making and sealing device

The former of the machine will integrate the roll film into a specific shape to make a container for material packaging. After continuous film pulling, the machine will instruct the material to be fed into the roll film and accurately fed into the bag to ensure that the shape and size of the bag meet the packaging requirements. The bag will then be sealed. The sealing methods are divided into back sealing, three-side sealing, four-side sealing, etc. The bag will be heated by the aluminum block. The roll film material can adapt to the temperature of the aluminum block and will be tightly sealed together to ensure the safety and freshness of the food. It can adapt to different thicknesses and roll film materials and can customize the seal according to your needs. For example, if you need the bag to be fully filled with materials and without any air, you can customize the iron seal to meet this requirement.

Cutting device

After the sealing is completed, the film roll of the machine will be pulled down continuously and the material will be continuously discharged. At this time, the packaging machine needs to be able to cut the finished bag accurately and quickly, and the material must not be cut and the sealing effect must be good. This has certain requirements for the aluminum block of the sealing part, so as to ensure the production efficiency and quality of the packaging. Therefore, the cutting device is the last step of packaging and also a step to test the accuracy of the packaging machinery. We can check whether it is sealed tightly and whether the weight of the material in the packaging bag is accurate. After that, the packaged finished product is transported, and a finished product conveyor belt can be used so that the finished product can be collected for sale.

Controls device

The control device is the core system of the vertical packaging machine, which coordinates the operation of the entire machine. The operator only needs to simply set the packaging weight and start the machine, and the rest can be left to the control system for packaging. It will send instructions to the material supply device, bag making and sealing device, and cutting device to start packaging the materials. The PLC system is used to control the entire machine and accurately measure and monitor the packaging process. This is a major advantage of the control system. The highly automated operator only needs simple settings to let the machine automatically package, which greatly saves time and costs and improves production efficiency. All of this is thanks to the control system.

The working of vertical packaging machine has to go through the above steps of material supply, weighing by weighing bucket, bag making and sealing, and cutting to complete the packaging of materials. Vertical packaging machine can help entrepreneurs create higher profits and is deeply loved by entrepreneurs. I think after the above introduction to vertical packaging machine, you must have some understanding of it. Next, I would like to introduce its advantages to you, help you to better understand it, and provide you with some help when choosing a packaging machine.

Advantages of vertical packaging machine
High efficiency and automation
The packaging machine can carry out packaging continuously. The powerful control device introduced above can automatically complete the packaging steps of the machine without too much manual intervention. The packaging speed can be nearly 100 packages per hour, which improves your work efficiency, reduces manual operation, reduces work intensity and frees your hands.

High packaging accuracy

The above article introduces the role of the weighing bucket in the vertical packaging machine, which shows the weighing accuracy of the packaging machinery. Reasonable weighing can avoid wasting packaging materials and save costs. Accurate weight can make your company more trustworthy and reduce disputes caused by insufficient weight.

Save space

Since the packaging machinery is designed to be vertical, it occupies a small area and can be perfectly integrated into various scenes. It is suitable for you to place it in any workplace, from factory buildings to small family businesses. It is especially practical for entrepreneurs with limited space.

quality assurance

In order to ensure that the finished products packaged by the machine can be well sealed to ensure the quality of the products, the packaging machines will undergo a series of tests to meet the factory standards. The advanced seals can accurately seal the packaging of liquids and powders without leakage. This not only ensures the quality and safety of the products, but also improves the market competitiveness of the products.

As a machine that can package powder, particles, liquids and other materials, the working principle of vertical packaging covers efficient, accurate and reliable packaging performance, providing a satisfactory packaging solution for packaging machinery. The five major devices, including material supply device, material weighing device, bag making and sealing device, cutting device and control device, constitute the vertical packaging machine, which plays their respective roles to work for you.
