Although the computer control system is still relatively reliable, an unrepairable hardware failure can cause the cutter to stop working. In view of the above reasons, we have implemented a transformation of the 8019 computer control system. PLC selection, system design and control functions. PLC's selection of 8019 computer control system only processes the switch level signal, using the logic operation function, there are 42 I / O points, and PLC control can be reduced to 15 input, 12 output, so we chose A micro PLC that can meet the requirements of logic operation and has strong anti-interference ability. The use of micro-PLC not only fully meets the requirements of logic operation and production process, and does not require the purchase of a dedicated programmer. Generally, the microcomputer can be programmed. Because "8019" still has value in use, the system is designed to be a micro-GEPLC and "8019" as a backup system. When "8019" cannot be used, the PLC can completely replace it. The design of the control system is in the standby system. The 27 I/O signals and signal power of the PLC are not laid with new cables, but the cable is shared with the 8019 I/O signals, and the switch function is realized by the button switch. (Finish)
Stitch bonding machine is a type of textile machinery used to create non-woven fabrics. It works by mechanically interlocking fibers together using a series of needles and threads. The machine can produce fabrics with a variety of textures and properties, such as thickness, elasticity, and strength. Stitch bonding machines are commonly used in the production of clothing, upholstery, and automotive textiles. They are also used in the medical industry to create wound dressings, bandages, and other medical textiles.
