Belt conveyor automatically detecting and adjusting tension

Abstract

The invention relates to the technical field of belt tensioning wheels, in particular to a belt conveyor automatically detecting and adjusting tension. The belt conveyor comprises a rack, a belt, a tensioning wheel and shaft lugs connected to the rack. A shaft hole is formed in the position, close to one end, of each shaft lug. Shaft parts at the two ends of the tensioning wheel are rotationally connected into the shaft holes of the shaft lugs on the two sides correspondingly. The belt conveyor is characterized by further comprising a tension detecting and adjusting device, and the signal endsof hydraulic pressure sensors of the tension detecting and adjusting device are in both-way connection with the signal input end of a control system. Compared with the prior art, the structure characteristics of the belt conveyor are sufficiently combined; commonly, the conveyor only needs the two hydraulic pressure sensors, the design of the control system is relatively simple, a real-time tensioning force curve and abnormal alarms can be provided for production and management personnel in combination with a man-machine interaction system, the tension of the belt conveyor can be detected inreal time and finely adjusted, the tension of the belt conveyor is kept to be constantly stabilized near the set value, and stability of production technology parameters is ensured.

Description

technical field [0001] The invention relates to the technical field of belt tensioning wheels, in particular to a belt conveyor with automatic tension detection and adjustment. Background technique [0002] Belt conveyors are widely used in the field of granular material transportation, and have the advantages of large conveying capacity, simple structure, convenient maintenance, and stable conveying. [0003] The belt conveyor needs to maintain sufficient tension during operation, otherwise it is easy to deviate and slip; but if the tension is too large, the life of the belt conveyor will be shortened. [0004] The current belt conveyor tension adjustment is mostly static. That is, tension when the belt is first installed and then no longer adjusted. After a period of production, it is judged from experience that the belt tension is not enough, and then stop the machine for adjustment. The method of adjustment is to increase the static counterweight or adjust the length ...

AI Technical Summary

Problems solved by technology

It is not conducive to real-time grasp of the production conditions of the belt conveyor

[0006] 2. The tension adjustment is not timely, resulting in hidden dangers in production

The tape of the belt has the characteristic that it will be stretched for a period of time during production. Therefore, it must be adjusted tightly when it is first adjusted, and it will become loose after a period of work. Untimely adjustment will lead to uncontrollable changes.

And it needs to stop and adjust, which affects the efficiency of production

[0007] 3. It needs the experience of the operator to judge, the accuracy of the adjustment is not high, and there is a lot of randomness

Affect the stability of the production process and production process
