Das Steuerungssystem der Kunststoffpelletmaschine umfasst ein Heizsystem, ein Übertragungssystem, ein Kühlsystem und ein Prozessparameter-Messsystem, das hauptsächlich aus elektrischen Geräten, Messgeräten und Aktuatoren (d.h. Steuerpanels und Arbeitsstationen) besteht.

The main function of the plastic pellet machine control system is: the main auxiliary drive motor for control and adjustment, the output of speed and force meets the process requirements, and can mainly assist the coordination; the plastic molding machine that tests and adjusts the temperature, pressure, and flows; realizes the whole device Control or automatic control.

The electrical control of the extrusion device in the production line is roughly divided into two parts: drive control and temperature control, which realizes the extrusion process including temperature, pressure, and cooling.

Extruder zur Granulation von Abfallkunststoff

1, Kunststoffpelletmaschine Temperaturregelung des Hosts

Plastic wire and cable insulation and jacket extrusion are characterized by viscous flow based on thermoplastic deformation.

In addition to the required plastic pellet machine screw and external heating barrel, the plastic melt is extruded, and the screw extrusion plastic itself is heated, the temperature requirements of the host should be considered in general, therefore, should not only consider the heater heating on and off Also consider the factors that cool the hot screws.

The plastic pellet machine requires correct and reasonable determination of the position and installation method of the thermocouple of the measuring component. The reading from the temperature control meter can reflect the actual temperature of the component.

The accuracy and system of the temperature control instrument should be well matched, and the stability of the temperature control system of the whole plastic pellet machine can meet the requirements of various plastic extrusion temperatures.

2, Regelung der Schraubendrehzahl der Kunststoffpelletmaschine

An important technical requirement for plastic pelletizers to adjust screw speed and stability is host transfer. The screw speed directly determines the quantity and speed of the product.

To achieve high yield in normal production, it is necessary to achieve the speed required for the screw speed requirement of the plastic pellet machine.

Since the fluctuation of the rotational speed will cause fluctuations in the quality of the impact extrusion, a change in the diameter of the cable will occur if the linear velocity of the traction does not change.

3, Kunststoffpelletmaschine Durchmessersteuerung

As mentioned above, in order to ensure the diameter of the product cable, in addition to the need to control the core (core) dimensional tolerances, extrusion temperature, screw speed, and a traction device, it should also ensure control of line speed and outside diameter measurement.

In plastic pellet machine equipment, the cable outer diameter should be tested at any time, and the traction or screw speed is adjusted by the feedback of the error signal, and the correct diameter is exceeded.

4, Kunststoffpelletmaschine die Anforderungen an die Steuerung der Wickelspannung zu erhalten

Um sicherzustellen, dass die konstante Spannung erforderlich ist, um von der leeren Scheibe bei unterschiedlichen Liniengeschwindigkeiten zu arbeiten, ist es wünschenswert, den Drahtspannungsanpassungsmechanismus des Verdrahtungsgeräts zu erhalten oder die konstante Liniengeschwindigkeit und das elektrische System der konstanten Spannungswicklung zu berücksichtigen.
