[0002] Belt conveyor, also known as belt conveyor, is a continuous conveying machinery that uses a flexible conveyor belt as a material carrying and traction component. It is suitable for conveying bulk materials and finished items in horizontal and inclined directions. It can also be used in assembly lines for certain process operations. It works stably and reliably, has strong adaptability to materials, has a large conveying capacity, and is widely used.
[0003] The main function of the belt conveyor speed measuring device is to detect the real-time running speed of the belt conveyor and transmit the speed signal to the control system or host computer and other equipment for data processing and control. Through the measurement of the speed measuring device, abnormal conditions of the belt conveyor such as slippage, overload, etc. can be discovered in time, and corresponding measures can be taken to prevent and deal with them, so as to ensure the safe and stable operation of the belt conveyor.

Since the speed measuring devices are immovable, they cannot adapt to changes or abnormal conditions in the operating state of the belt conveyor. If the belt conveyor vibrates or shifts, the fixed speed measuring device may not be able to accurately measure the speed, resulting in inaccurate measurement results. Its position and installation angle may not be adjusted according to actual needs and cannot meet the needs of various measurement scenarios. Utility Model Content
