Vertical Form Fill Seal (VFFS) machine, commonly referred to as vertical ffs machine, and volumetric cup are indispensable equipment in the modern packaging industry. Their combined use provides an efficient, precise, and economical solution for product packaging. This article will explore the working principles, advantages, and practical applications of these two types of equipment.
Introduction to Vertical FFS Machine
Vertical ffs machine s are capable of automatically completing a series of packaging processes including bag making, filling, sealing, and cutting. They are mainly used for packaging materials such as powders, granules, liquids, and semi-fluids. The design of vertical ffs machine allows for rapid and continuous packaging, greatly improving production efficiency.
Working Principle
The working principle of vertical ffs machine involves a series of mechanical devices and control systems to carry out the packaging process. Initially, the packaging material (usually roll film) is pulled out and formed into a tubular bag by a forming device. Then, a volumetric cup or other measuring device fills the bag with a predetermined amount of product. Finally, a heat sealing device seals the bag opening, and a cutter separates the individual bags.
Advantages
- High Efficiency: Vertical ffs machine can continuously perform packaging, significantly increasing production speed.
- Flexibility: The size and shape of the packaging bags can be adjusted according to different products and packaging requirements.
- Material Savings: As bags are made directly from roll film, material waste is reduced.
The Role of Volumetric Cups
Volumetric cup s are simple and effective measuring devices commonly used for the quantitative packaging of solid or granular materials. They determine the amount of material to fill based on the physical space of the cup, making them particularly suitable for products that do not require high precision in weight.
Working Principle
The working principle of volumetric cup is to use a set of cups with fixed volumes to measure the product. During the packaging process, the volumetric cup rotates to the filling position, the material falls into the cup by gravity, and then the cup rotates to the discharge position, pouring the material into the formed bag.
Advantages
- Simple and Efficient: The structure of volumetric cups is straightforward, making them easy to operate and maintain.
- Cost-Effective: Compared to other complex measuring systems, volumetric cup is more cost-effective.
- Wide Applicability: Suitable for a variety of solid and granular materials.
Practical Application Cases
In various industries such as food, pharmaceuticals, and chemicals, the combination of vertical ffs machine and volumetric cup has become the standard configuration in the packaging process. For example, in the food industry, they are used for packaging snacks, candies, coffee powder, etc.; in the pharmaceutical industry, they are used for packaging tablets, capsules, etc.
Conclusion
The combined use of vertical ffs machine and volumetric cup has brought revolutionary changes to the packaging industry. They not only improve packaging efficiency but also reduce production costs while ensuring the quality of product packaging. With continuous technological advancements, these devices will become more intelligent and better meet market demands in the future.
