Full-automatic tensioning control system and method used for rubber belt machine

Abstract

The invention discloses a full-automatic tensioning control method used for a rubber belt machine. The full-automatic tensioning control method includes the steps of in the starting or stopping or running process of the rubber belt machine, calculating the minimum tension F<min> required by the rubber belt machine, and determining a standard tension range according to the F<min>; detecting the belt tension F' of the rubber belt machine; and comparing the detected belt tension F' with the standard tension range, and if the F' is out of the standard tension range, tensioning or loosening a belt of the rubber belt machine till the detected belt tension F' is within the standard tension range. By means of the full-automatic tensioning control method, the tension of the belt can be adjusted in real time in the starting or stopping or running process of the rubber belt machine.

Description

technical field [0001] The invention relates to the technical field of tape machines, in particular to a fully automatic tension control system and method for tape machines. Background technique [0002] The belt conveyor is the main transportation equipment for mine operations. The tension control of the belt conveyor can prevent the belt of the belt conveyor from slipping on the driving drum and reduce the running resistance of the belt between the idlers. The existing tension control system uses a tension sensor to detect the tension of the belt, and the detection signal is fed back to the PLC (Programmable Logic Controller, programmable logic controller). When the tension of the belt is greater (or less) than the standard tension value preset in the system, the belt is adjusted Tension degree, so that the belt tension can be maintained within the preset tension range. This automatic tensioning device can realize the automatic adjustment of belt tension, but, since the s...

Problems solved by technology

This automatic tensioning device can realize the automatic adjustment of belt tension, but, since the standard tension value in this system is pre-set, pre-stored, when the set tension value of the system needs to be changed (for example, retractable belt type The belt length of the conveyor varies with the operating conditions, and the required belt tension value also changes), which requires manual correction by the operator to adapt to the change in the length or load of the belt conveyor

Most of the current automatic tensioning systems rely on the experience of operators to manually modify the system tension value without theoretical verification, and the accuracy is difficult to guarantee. In practice, most people only adjust the system tension value when they have to modify it. Therefore, excessive tension or slippage of the tape machine often occurs, which is no longer applicable to the modern mine operating environment with increasing automation.
