Intelligent roller friction testing machine of conveyor belt

Abstract

The invention relates to an intelligent roller friction testing machine of a conveyor belt. The intelligent roller friction testing machine comprises a drive system and a tension system, wherein the drive system is used for driving a roller to rotate, and the tension system is used for regulating the tension of a sample to be detected in real time. The intelligent roller friction testing machine is characterized in that the tension system comprises a tension sensor which is arranged on a linear guide rail and is capable of automatically detecting the tension, and the tension sensor is connected with a direct current motor by a ball screw. The intelligent roller friction testing machine provided by the invention is suitable for roller friction tests of a fabric core flameproof conveyor belt and other flameproof conveyor belts. The testing machine comprises an intelligent testing device which can be used for automatically adjusting a constant tensioning force, automatically increasing the constant tensioning force according to a standard after operating during a certain time, automatically detecting a broken belt, automatically detecting open fire, automatically detecting temperature, printing an operation test curve and reporting data; and moreover, a fully enclosed smoke collecting and discharging device is adopted, so that an environment pollution index is reduced.

Description

technical field [0001] The invention belongs to the technical field of conveyor belt quality detection machinery, and in particular relates to an intelligent roller friction tester for conveyor belts. The intelligent tester complies with the experimental requirements of MT914-2008 Appendix F (normative appendix). Background technique [0002] The rubber conveyor belt is an expensive and poorly durable component. During use and operation, the conveyor belt will be subjected to loads of various natures and sizes. The working surface and edges will be worn for a long time, and severe fractures will occur. Sparks can cause mechanical accidents and fires. Therefore, in the preparation process of rubber conveyor belts, it is necessary to measure the physical parameters of the conveyor belts such as wear resistance and flame retardancy, so as to ensure the qualified rate of the products. And this process is done by roller friction testing machine. [0003] The roller friction tes...

AI Technical Summary

Problems solved by technology

There are certain problems in the above two methods. The test machine using the lever weight is cumbersome to operate, and with the lengthening of the friction sample, the weight force will change with the length of the sample; Although it is possible to add a constant pulling force; the operation is cumbersome, the labor intensity is high, and the pollutants produced will cause great harm to the human body; moreover, due to manual operation, the test conditions and the set conditions are artificially deviated. affect the outcome

[0004] In addition, the current existing testing machine needs manual inspection from time to time during the testing process, and cannot record the over-temperature, open flames, or conveyor belt breaks that occur during the testing. Experimental data are difficult to compare, etc.
