Main chain tension predicting control system of paraffin continuous shaping machine

Abstract

The invention discloses a main chain tension predicting control system of a paraffin continuous shaping machine, which solves the alarming problem when the conventional system fails. The invention adopts the following specific technical scheme: the main body structure of the tension predicting control system mainly comprises a transducer, a revolving coder, a tension sensor detecting element, a signal detecting device, a signal transmitting and processing device and a configuration software and expert diagnostic software system; a control system ARM9 and an operation system WIN-CE of a host computer accurately and quickly sequence and store performance parameters in a related database; the expert diagnostic software system finishes data acquisition and signal comparison, analyzes the running state of equipment and finishes pre-diagnosis for the abnormal running fault of the equipment; and the system can send an early warning signal or automatically stops in necessity for processing the failure. The system has the advantages that: coordinate positioning management on the main chain is performed so as to predict the failure in advance, diagnose the failure in time and realize control in advance and prediction as target to further ensure stable operation of the main chain.

Description

technical field [0001] The invention relates to a tension prediction control system, in particular to a main chain tension prediction control system of a paraffin continuous molding machine, which solves the problem of main chain tension prediction control. Background technique [0002] The main chain tension device of the paraffin wax continuous molding machine is driven by the transmission sprocket to move the main chain. The transmission sprocket shaft at the end is connected to one side of the tension sensor through a cable, and the other side of the tension sensor is connected to the pull rod and pull at the end of the main chain guide rail frame. Connect with devices such as tight springs. What the display of existing main chain tension failure adopts is single warning device, and what this device used is conventional tension (or pressure load) sensor, computer+signal acquisition board, MODBUS communication mode and common software. Its shortcomings are: (1) Because o...

Problems solved by technology

Its shortcomings are: (1) Because of its single function, it can only do routine alarms, and cannot accurately and timely display the fault point. After the fault occurs, it takes a long time to find it by relying on manual on-site inspection and empirical judgment analysis; (2) all Alarms and shutdowns occur after the fault occurs, often causing the main chain to be broken, the wax plate frame and the wax plate to be damaged, which increases the maintenance workload, and each maintenance time is as long as two to three shifts.

(3) Since each shutdown is a sudden stop in an emergency, it directly causes chaos in production, increases recovery time, affects normal production, and reduces effective start-up working time

(4) Due to the technical lag, the data exchange time is at the second level, and it is impossible to perform position calibration data processing with the host

And its self-contained system is complex and huge, with a large footprint, high cost, and large investment. Each device is more than 250,000 yuan, and the cost of use is also high.
