• The whole machine operation system is controlled by Siemens PLC module, which can be controlled by single action or linkage speed regulation. Visual operation via Siemens 10.1-inch touch screen
•  Communication control is adopted between PLC and frequency converter, which has higher control accuracy and faster response than analog variable speed regulation; At the same time, PLC is equipped with Ethernet interface, and users can monitor remotely
• The whole machine is a dual control system: the touch screen is used to set the analog speed regulation and the manual self reset knob speed regulation. The parameters can be set and adjusted freely through the touch screen, and can also be controlled by the self reset knob speed regulation
• The host machine and traction motor of the extrusion machine are all brand AC motors, controlled by the sinusoidal frequency conversion speed regulation system. The latest generation of intelligent electronic display calculus temperature controller is selected as the temperature control instrument, and the temperature control accuracy is ± 2 ℃
• The panel is equipped with various instruments, indicators, switches and other necessary elements, and various overload, overheating, overcurrent and other protection functions are complete
• Low voltage components of the whole machine are all made of high-quality brands, which have the advantages of stable starting, running and stopping of the production line, energy conservation and consumption reduction
• The control box is spliced by high-quality anodized aluminum profiles and aluminum die-casting corner components, which is simple and stable in appearance and easy to operate. The dust-proof filter device is installed in the main control box to prevent dust from affecting the service life of electrical components in the cabinet.
