After contacting the packaging machine industry, through understanding the packaging machine, let us have an understanding and cognition of this kind of equipment, especially the composition of the packaging machine system. Looking at many packaging machines in the packaging machine industry, although they are different in function and performance, the basic components of the packaging machine system are basically the same. Today, Xiaobian takes you to understand the five parts of the basic structure of the packaging machine system, as follows:

Packaging machine five system components: weighing part, pneumatic part, control part, electric part, mechanical part.

1. Weighing part: upper hopper, double screw feeder, weighing sensor, weighing hopper and suspender of rotating arch breaking device.

2. Pneumatic part: 0.4 ~ 0.7MPa air source, air cylinder, air source pipe.

3. Control part: PLC, f701 controller, universal switch (bag clamping switch) and control button.

4. Electric part: solenoid valve.

5. Mechanical part: lower hopper, bag door, hopper door.

Among the five main components, the control part is the core of the system, which determines the important parameter setting and the sequence of controlling the mechanical equipment. Generally, in the f701 controller, the main parameter setting and adjustment of the scale have been completed before delivery, and the instrument setting parameters have been locked.

The five components cooperate to complete the working process of the packaging machine, roughly as follows: turn on the power supply, hang the bag, toggle the bag clamping switch, control the solenoid valve through PLC, make the bag clamping cylinder act, clamp the bag, and press the operation switch of the scale; The blanking door is opened to start feeding into the weighing hopper, and the weight is measured by the sensor installed on the weighing hopper, and the measured value is transferred to the f701 instrument after conversion; According to the weight value, the f701 instrument carries out corresponding control on some parts, through such processes as coarse feeding → medium feeding → fine feeding → automatic weight compensation, etc., to make the material value meet the set requirements, and then opens the weighing hopper door to make the material fall into the packaging bag.
