★Introduction to chemical fiber equipment☆Chemical fiber production is a long-flow continuous production, and polypropylene, polyester filament production equipment is a common equipment. The equipment mainly includes: spinning machine (mainly screw spinning box, spinning assembly, spinning pump, metering pump, cooling blower and oiling, biphenyl heating, etc.). Winding machine (friction roller, collet, groove).
★The control system of chemical fiber equipment includes:
☆Wire machine control system, PLC control of 4 screws 32 spinning pumps and 1 oil pump frequency converter, 4 spinning box temperature and pressure monitoring, the system has 4 on-site I/O, passing people The machine interface realizes the setting, modification, and related data collection of the process parameters, and controls the operation of the above equipment.
☆ Each roller between the draft roller 1 and the drafting roller 6 may have a power generation operation state, that is, a reverse drag phenomenon when the tow is drawn, which may cause the draft ratio to be unstable. For this reason, the frequency converter adopts a common DC bus power supply mode, and a total of six inverters of the traction rollers 1 to 6 are powered by one rectifier unit, so that the voltage of the DC bus does not rise and the stability of the draft ratio is ensured.
☆ Winding control system, PLC controls the logic and speed of the traverse and the spindle.
