塑料颗粒机控制系统包括加热系统、传动系统、冷却系统和工艺参数测量系统，主要由电器、仪表和执行器（即控制面板和工作站）组成。

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.

1, 塑料颗粒机 主机温度控制

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.

塑料颗粒机螺杆转速控制

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.

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.

为了确保在不同线速度下从空盘工作所需的恒定张力，最好接收布线设备的线张力调整机制，或者考虑恒定线速度和恒定张力绕线的电气系统。
