Precautions for the operation of the control system of the masterbatch granulator production line

The electrical control of kneading equipment is roughly divided into two parts: drive control and temperature control, which ends the kneading process including temperature, pressure and cooling.

1. Temperature control of the main machine of plastic pellet machine

Plastic wire and cable insulation and sheath kneading are characterized by viscous activity based on thermoplastic deformation. In addition to the requirements of the plastic pellet machine screw and external heating barrel, plastic melt extrusion, and spiral kneading plastic itself heating, the temperature requirements of the host should be considered from the whole, therefore, should not only consider the heater heating of the opening and closing, but also consider the cooling heat of the screw elements. The plastic pellet machine requires correct and reasonable identification of the orientation and equipment method of the thermocouple of the measuring element, and the reading from the temperature control surface can reflect the actual temperature of the component. The accuracy and system of the temperature control surface should be well matched, and the stability of the temperature control system of the entire plastic pellet machine meets the requirements of various plastic extrusion temperatures.

2. Screw speed control of plastic pellet machine

An important skill of plastic pellet machine scheduling screw speed and stability requires host transmission. The screw speed directly determines the number and speed of the product, and the normal production should end the high-yield demand as far as possible to reach the speed required for the screw speed of the plastic pellet machine. Because the speed is not resolute, the impact kneading quality will not be resolute, so if the speed of the tow line is not changed, it will lead to a change in the diameter of the cable.

3. Diameter control of plastic pellet machine

As mentioned above, in order to ensure the size of the product cable diameter, in addition to the need to control the core (center) specification of public service, kneading temperature, screw speed and traction equipment, the control line speed and outer diameter measurement should also be guaranteed. In the plastic pellet unit equipment should check the outer diameter of the cable at any time, adjust the traction or screw speed through the response of the fault signal, and exceed the correct diameter.

4. The plastic granule machine gets the requirements of coil tension control

In order to ensure that the constant tension is required from the empty disk operation under different line speed rolls, it is hoped to receive the wiring equipment storage line tension adjustment mechanism, or consider the constant line speed and constant tension winding electrical system, etc.
