Fina lly the research of plastic woven bag sealer achieves the desi red requirements. This machine achieves automatic control of the entire sealing pr ocess, and counted urately, reliable action. First, through extens ive research and analysis of plastic woven bags sealer process, I designed the overall pr ogram for plastic woven bag sealer. Second, I designed automatic folding sector, automatic feeding sector, pressure bags sector and qu ick sending sector. Finally, according to acti ons and parameters, I desi gned electrical control systems. The system adopt s Siemens PLC S7-200 and te xt display TD400C which connect to work control layer. the lower layer is a device layer th at connects with the variety of measur ement and control equipment as well as remote I/O points of PLC equipment. Use STEP 7 Mi cro WIN software to program and upload the program to the PLC, and us e the software to design HMI.
