In the supermarket, you will see bags of milk and juice, which are inseparable from the liquid filling machine. The full-automatic liquid filling machine can make a variety of liquid packaging bags, cosmetic samples, bagged juice, pure milk, etc. for us. The filling machine has higher precision and stability, and is more efficient than traditional manual operation, and the gram weight is more accurate, so it is deeply loved by enterprises.

I will introduce the advantages of liquid filling machines in detail, which can provide you with more reference value when you choose a fully automatic liquid filling machine. Generally, when purchasing packaging machinery, you need to compare and understand the machine in many aspects, so it will take some effort. When you understand it better by reading this article, and think that the benefits of liquid filling machines outweigh the homework you need to do when purchasing.

Precise filling-saving you costs

The fully automatic filling and packaging machine is controlled by a PLC system and is fully automated. You only need to set the weight you need on the panel, and the filling machine will distribute instructions for packaging through a powerful control system, including weight, suction, feeding, sealing, and packaging. It can ensure that the error of the finished package is only 0.01, which is impossible for manual packaging. It ensures the stability of product quality, avoids complaints caused by inaccurate weight, and increases the credibility of your company.

The following machine is a high-speed liquid filling and packaging machine. It uses a plunger volumetric pump for filling and metering. It uses the pressure between the plunger and the pump chamber to cooperate. When the plunger moves backward, negative pressure is formed in the pump chamber, the inlet check valve opens, and the liquid is sucked into the pump chamber; when the plunger moves forward, the pressure in the pump chamber increases, the inlet check valve closes, the outlet check valve opens, and the liquid is discharged from the pump chamber. By controlling the plunger, the volume of liquid discharged each time can be accurately controlled to achieve the purpose of accurate filling.

Efficient production-improved packaging efficiency

The working efficiency of the liquid filling machine is determined by the material being packaged. If the material can be packaged well, it can package hundreds of packages per hour, which greatly improves the working efficiency and can save you time and cost. The fast packaging can meet the needs of large-scale production and reduce the labor intensity to truly free your hands. You only need a liquid filling machine to realize an easy and intelligent packaging line.

This is because the feeding device of the filling machine needs to be able to quickly and accurately supply the packaging materials and products to the packaging position, and realize fast sealing, film pulling, material feeding, and sealing in one go. You can choose the machine according to your material and the weight of each package of packaging. Generally speaking, the heavier the weight of the finished product, the lower the packaging speed of the machine. The weight and speed of the packaging are relative values, so you can customize it. The following packaging machine is a high-speed filling machine, suitable for small-weight packaging, and can package nearly 90 packages per minute.

Wide applicability - provides a variety of options

Liquid filling machines can be used for different packaging methods, such as bottles, small bags, etc., and also for different types of liquids

In the cosmetics industry
Liquid filling machines can package toners, makeup removers, perfumes, etc.

In  the food industry

Liquid filling machines can package soy sauce, juice, milk, etc. The filling machine is made of 304 stainless steel that can directly contact food to ensure food safety.

In agriculture
Liquid filling machines can fill pesticides, herbicides, etc.

Liquid filling machines are suitable for multiple industries. They are present in every industry to create profits for people, and the model of the filling machine can be selected according to your needs. It can be applied to large factories and small entrepreneurs. You can choose a small machine or a large machine, depending on your needs.

Tight seal - ensure product quality
The liquid filling machine can customize the machine's seal according to different needs. If you want no air in the finished product, you can customize the iron seal to achieve the full cutting process. Another sealing method is heat sealing, which melts the packaging material by heating the aluminum block and applies pressure to make the material stick together. After cooling, it achieves a sealing effect. The powerful control system will cooperate with the aluminum block to adjust the appropriate temperature. According to the different materials of the roll film, different temperatures can be set so that the product can be packaged. Tight sealing ensures the freshness and safety of the finished product.

Working principle of liquid filling machine

The liquid to be filled is stored in the liquid storage tank. The liquid level difference generates gravity, and the liquid naturally flows into the container to be filled. This type of filling machine is usually divided into two modes: timed filling and fixed volume filling. Timed filling controls the filling volume according to the set time, which is suitable for occasions where the filling speed requirement is not high and the filling volume accuracy requirement is relatively low; fixed volume filling is to fill by setting the liquid volume in the container, and stop filling when the liquid reaches the preset volume. This type of filling machine is only suitable for filling low-viscosity liquids, such as milk, wine, etc.

Through the above introduction, do you have a certain understanding of liquid filling machines? Liquid filling machines are deeply loved by people for their high precision, high efficiency and wide application range.
