DETAILS
Heiko independently developed special PID digital instrument control system and PLC closed-loop control system suitable for plastic precision extrusion industry.
PID digital instrument open-loop control: The system adopts PID digital instrument and frequency conversion control mode. There are temperature control module, pressure control module and flow control module inside. It can detect the temperature, pressure and speed to meet the customer's extrusion requirements.
PID digital instrumentation closed-loop control: the system adopts PID digital instrumentation and frequency conversion control mode. There are temperature control system module, pressure control module and flow control module inside, which can automatically realise the control of temperature, pressure and rotational speed, and it can realise the automatic adjustment of the rotational speed of the host machine through the change of the value of the pressure at the outlet of the melt pump, which is simple to operate and achieves the effect of balanced extrusion.
PLC control system: adopting PLC programmable control system mode, with advanced touch screen as human-machine interface, it can automatically realize the control of temperature, pressure, flow rate and rotational speed, and the automatic adjustment of the host's rotational speed, better realize the pressurizing and stabilizing function of the melt pump, improve the precision and stability of the control, and realize the linear and balanced extrusion, with strong operability.
Configured with high-end melt pressure sensor and sound and light alarm system, it automatically alarms when it needs to change the mesh, prompts to change the mesh, and excludes the impact on product quality due to excessive clogging of the mesh. Distinguishable temperature control, so that the heating temperature of the screen changer is accurate and stable.
