With the continuous advancement of science and technology, a variety of intelligent packaging equipment has emerged. Among them, the bagged liquid filling machine has become an important part of the modern packaging industry with its unique advantages. This article will introduce in detail the structure, working principle and application of the bagged liquid filling machine in various industries, and analyze its advantages and disadvantages, and finally forecast the development trend of the bagged liquid filling machine.

　　1. Basic structure and working principle of bagged liquid filling machine

　　The bagged liquid filling machine is mainly composed of a filling head, a metering device, a bagging mechanism, a transmission system, a control system and a frame. Its working principle is mainly to inject liquid into the packaging bag through the filling head, and then control the volume of the liquid by the metering device to ensure that the amount of liquid in each packaging bag is consistent. Finally, the packaging bag is sealed by the sealing device to complete the entire packaging process.

　　2. Application scenarios of bagged liquid filling machine

　　As a highly efficient liquid packaging equipment, the bagged liquid filling machine is widely used in many industries such as food, chemical industry, and medicine. For example, in the food industry, the bagged liquid filling machine can be used for the packaging of condiments, fruit juices, milk and other liquids; in the chemical industry, it can be used for filling paint; in the pharmaceutical industry, it can be used for disinfectant, liquid medicine And other liquid packaging.

　　3. Types and characteristics of bagged liquid filling machines

　　Type: According to different filling principles, bagged liquid filling machines can be divided into two types: gravity filling and pressure filling. Gravity filling is to transport the liquid from the high-level container to the packaging bag through the action of gravity; pressure filling is to transport the liquid from the liquid storage tank to the packaging bag through the action of pressure.

　　Features: The bagged liquid filling machine has many advantages such as high degree of automation, convenient operation, high production efficiency, accurate measurement, environmental protection and no pollution. It can not only greatly reduce the labor intensity of workers and improve production efficiency, but also effectively ensure product quality and food safety.
