The 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.
Three edge-sealing bag making machine 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 zipper bag making machine has high precision and machining efficiency of rectification, still can provide the corresponding energy efficiency at the same time
The control system of zipper bag making machine is realized by fuzzy control technology of three-side bag making machine. 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.
The whole machine adopts foreign PLC, man-machine interface centralized control. Stable performance, easy to operate and maintain. The operation interface can be switched between Chinese and English. Its parameters are displayed by the human-machine interface in real time, and can be preset bag-making speed, bag-making length, temperature, counting, finished product transportation and so on. Bag-making machine LPC automatic deviation correction, dual photoelectric tracking feeding, automatic constant tension control AC frequency conversion constant speed automatic feeding. Batch function: the workbench has batch function, batch quantity can be preset. The punching mode of the equipment can be set as continuous, interval and stop, and the punching time can be preset.
