Plastic extrusion equipment is mainly composed of a host and auxiliary machines. The plastic extruder is generally called the main machine, and the subsequent equipment matched with it is called the auxiliary machine. The plastic extruder can be combined with various types of auxiliary machines (such as pipes, films and Heat preservation pipes, etc.) are combined to produce a variety of plastic products. Therefore, plastic extrusion equipment will be one of the indispensable equipment in the plastic processing industry, whether it is now or in the future. This article introduces the easy drive CV3100 series The application of 15KW frequency converter in plastic extruder is used to drive customer's transmission system and produce various types of plastic products.

 

Field application

5. Summary

 

Using the inverter to drive the extruder meets the customer's function of stepless speed regulation of the motor, so that customers can always pay attention to the machine operation on the spot, adjust the working speed of the extruder, and the smooth start of the inverter reduces the load on the equipment. The impact of the inverter prolongs the service life of the machine. The most important thing is that the frequency conversion has the functions of undervoltage, overcurrent, overload, overheating, phase loss, and short circuit protection, so that the machine runs reliably and smoothly.
