Liquid bag automatic filling machine is a high-efficiency and high-precision filling equipment, which is widely used in various fields such as chemical industry, food, and medicine. This article will introduce the relevant knowledge of the liquid bag automatic filling machine in detail from the aspects of principle, structure, work process, and characteristics.

　　A. Principle

　　The liquid bag automatic filling machine adopts PLC control technology, and realizes the operation and parameter setting of different bag types through the touch screen control system. During the filling process, the metering pump draws the liquid from the liquid storage tank, and sends it to the filling head after being measured by the flow meter, and the filling head is driven by the cylinder to complete the filling action. At the same time, the sensor detects whether the bag is in place and ensures filling precision and accuracy.

　　B. Structure

　　The main parts of the liquid bag automatic filling machine include: metering pump, flow meter, filling head, electrical control system, conveyor belt, sensor, etc. The metering pump realizes the precise metering of the liquid through the flow meter, and the filling head is driven by the cylinder to set the air pressure and control the filling speed.

　　C. Workflow

　　The workflow of the liquid bag automatic filling machine is as follows:

　　1. The empty bag enters the conveyor belt, and the sensor detects whether the bag is in place.

　　2. After the control system recognizes the bag type and the parameters are set, the metering pump starts to work to draw the liquid from the liquid storage tank.

　　3. The flow meter measures the liquid flow, and the filling head is driven by the cylinder to complete the filling process.

　　4. After the filling is completed, the bag continues to be sent to the next process by the conveyor belt.

　　D. Features

　　The liquid bag automatic filling machine has the following characteristics:

　　1. High precision: use metering pump and flow meter for filling, with high filling precision and strong accuracy.

　　2. High degree of automation: the entire filling process is automated, with high work efficiency and low labor costs.

　　3. Easy to operate: the touch screen control system is friendly, easy to operate, easy to learn and master.

　　4. Wide range of applications: It is suitable for bag filling of various liquids, emulsions and other products, and is widely used in chemical, food, pharmaceutical and other fields.

　　5. Compact structure: the equipment is small in size and occupies a small area, which is convenient for the layout and adjustment of the production line.

　　Liquid bag automatic filling machine is a high-efficiency and high-precision filling equipment, which can greatly improve filling efficiency and accuracy, reduce labor costs, and is widely used in various fields. This paper introduces the relevant knowledge of the liquid bag automatic filling machine in detail from the aspects of principle, structure, working process and characteristics.
