Most zipper bag making machines have already achieved intelligent control, which not only significantly improves the automation level of the equipment but also enhances the precision of bag making operations and reduces losses caused by errors. What kind of intelligent control system can play such an important role in zipper bag making machines?
The intelligent control system of the three-side sealing zipper stand-up bag making machine mainly consists of two parts: hardware and software. Let's start with its hardware system, which includes control circuits, data acquisition circuits, differential amplifier circuits, decoding circuits, alarm circuits, and other components. Of course, the most important one is the control circuit. The variable frequency voltage signal of the variable frequency motor is provided by the digital frequency converter. Since the input direction determines the forward and reverse rotation of the frequency converter motor, the circuit requires two bidirectional photoelectrically controlled silicon rectifiers to provide AC voltage, which helps the motor rotate to achieve deviation correction.
As for the software part of the system, it includes a variety of programs, such as control subroutines, data acquisition subroutines, data conversion subroutines, data processing subroutines, alarm processing subroutines, and fuzzy control subroutines. Each of them plays an important role. Through fuzzy control, the zipper bag making machine can achieve high deviation correction precision and processing efficiency, and also provide corresponding support for energy conservation.
Fuzzy control technology realizes the precise control of the intelligent control system of the zipper bag making machine. First, the optical system focuses and images the positioning reference line, and provides optical signals to the optoelectronic devices through the imaging process. After receiving the optical signals, the optoelectronic devices convert them into analog electrical signals. These signals are then converted into binary digital quantities through A/D conversion. The single-chip microcomputer reads these digital quantities and performs fuzzy processing in combination with the rate of change of the values. Then, it sends commands for forward/backward movement, left/right rotation, and start/stop, thereby controlling the movement and variable-speed offset of the bag making and sealing device, ensuring that the bag making and sealing process can be carried out accurately and normally.
