Online monitoring and maintaining system for plastic extrusion units

Abstract

The invention discloses an online monitoring and maintaining system for plastic extrusion units. The system comprises a monitoring module, a router and a human-computer interface module, wherein the monitoring module is used for obtaining the online process parameters of the plastic extruders; the router is used for transmitting the online process parameters of the plastic extruders to the human-computer interface module through a wired communication manner; the human-computer interface module is used for encapsulating the data transmitted by the router, displaying the de-encapsulated data and transmitting the changed process parameters to the monitoring module through the router. According to the online monitoring and maintaining system, the equipment operation and maintenance personnel can know the production line status of the modified plastic extruders at the sites or in control rooms in real time and carry out real-time adjustment and maintenance on the production process and the like through the human-computer interface module to ensure the product quality.

Description

technical field

[0001] The invention relates to the field of information monitoring, in particular to an online monitoring and maintenance system for an extrusion unit. Background technique

[0002] When the extruder is working, the process parameters include the screw speed, the temperature and pressure of each section of the barrel, the temperature and pressure of the machine head, the power consumed by the extruder transmission system and the heating system, etc. These process parameters have an important impact on the quality and output of the product, so it is necessary to monitor and control each process parameter within the specified range at any time.

[0003] At present, the measurement and control system of the plastic extruder mainly consists of a temperature measurement and control module, a pressure measurement and control device, and a frequency conversion governor. Each of the above parameter measurement modules is a relatively independent measurement cir...
