Most bag-making machines have realized intelligent control, which not only improves the automation level of the equipment, but also improves the accuracy of bag-making operation and reduces the loss caused by errors. What kind of intelligent control system can play an important role in the bag-making machine?

The intelligent control system of the three-side bag sealing machine has two components, one is hardware, the other is software. Let's first talk about its hardware system, which includes control circuit, data acquisition circuit, differential amplifier circuit, decoding circuit, alarm circuit and other components. Of course, the most important is the control circuit. The frequency conversion voltage signal of the frequency conversion motor is provided by the digital converter. Since the input direction will determine the positive and negative rotation of the frequency converter motor, two two-way optical silicon controlled SCR are needed in the circuit to provide ac voltage to help the motor rotation to achieve deviation correction.

And hose part includes the procedures of the system is also more, with control subroutine, data acquisition program, data conversion, data processing subroutine, alarm processing subroutine, fuzzy control subroutine, etc., each play an important role, through fuzzy control can make three edge-sealing bag making machine has a high correction accuracy and machining efficiency, but also can provide the corresponding energy efficiency.

Fuzzy control technology can realize the accurate control of the intelligent control system of three-side bag sealing. Firstly, the optical system is used to image the positioning marker line into focus and provide optical signals to the photoelectric devices through imaging. Photoelectric device receives the optical signal after converted into analog signals, the binary digital signal after A/D conversion, read by single-chip microcomputer combined with the value after the change rate of fuzzy processing, then issue the speed forward, backward, turn left, turn right command and open, the shutdown command, to control the movement of the bag packaging and variable offset, bag packaging can accurately to normal.
