Abstract
The utility model discloses a no-load protective system for an extruder. The system comprises a frequency converter, a driving motor, a screw, a cylinder, a communication module, a programmable controller and a human-computer interaction interface, wherein the motor is driven to work by the frequency converter, the frequency converter changes the working state of the motor, and the output end of the driving motor is connected with the screw and drives the screw to revolve; the programmable controller compiles a program in advance, current data of the frequency changer is read through the communication module, the data are analyzed, a command is sent, the state of the frequency controller is controlled through the communication module, and the human-computer interaction interface monitors changes of current and rotate speed parameters in rear time and sends out an alarm signal when the parameters are abnormal. The system provided by the utility model has the beneficial effects of being capable of monitoring and controlling the working states of the frequency controller and the motor in real time, immediately finding out abnormal phenomena and sending out an alarm signal to prevent equipment from being in a disable state for a long time so as to realize the purpose of protecting the equipment.
Description
Technical field
The present invention relates to a kind of equipment protection system, belong to electrical equipment control technology field.
Background technology
Rubber, plastic extruder, due to rotary screw and barrel length longer, screw rod end is in the raw time, gravitate, screw rod end can be sagging, running easily causes screw rod or machine barrel damage for a long time.And extruder is forbidden working long hours in the situation that not loading, in order to prevent this from occurring, need to take safeguard measure.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop a kind of extruder no-load protection system.Protection system is by transducer drive machine operation, and frequency converter changes the duty of motor, and drive motors output is connected with screw rod, drives screw rod running; Programmable Logic Controller preprogramming, read the current data of frequency converter by communication module, analyze Data Concurrent and go out instruction, by the state of communication module control frequency converter, and changed by human-computer interaction interface Real-Time Monitoring electric current and rotary speed parameter, when abnormal parameters, send alarm signal.Threshold D1 is set in programmable controller program, when current of electric D0 is less than after setting value D1, after elapsed time T1 time delay, first first carries out alarm, do not shut down; After elapsed time T2 time delay, report to the police and shut down, reaching defencive function.
Beneficial effect of the present invention: the duty of protection system energy Real-Time Monitoring and control frequency converter and motor, the phenomenon that can note abnormalities in time, and send alarm signal, and avoid equipment for a long time in disabled status, reach the object of protection equipment.
Brief description of the drawings
