Le système de contrôle de la machine à granulés plastiques comprend un système de chauffage, un système de transmission, un système de refroidissement et un système de mesure des paramètres de processus, principalement constitué d'appareils électriques, de compteurs et d'actionneurs (c'est-à-dire des panneaux de contrôle et des stations de travail).

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.

Extrudeuse de granulation de plastique de rebut

1, machine à granulés en plastique contrôle de la température de l'hôte

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, contrôle de la vitesse de vis de machine à granulés en plastique

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, machine à granulés en plastique contrôle de diamètre

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, machine à granulés en plastique obtenir les exigences du contrôle de la tension du rouleau

Afin de garantir que la tension constante est nécessaire pour travailler à partir du disque vide à différentes vitesses de ligne, il est souhaitable de recevoir le mécanisme de réglage de la tension du fil du dispositif de câblage ou de considérer la vitesse de ligne constante et le système électrique de l'enroulement à tension constante.
