Technical Field

[0001] The utility model relates to the technical field of belt scales, in particular to a device for measuring the time of a belt scale. Background Art

[0002] In industrial production, conveyor belt scales are widely used for measuring material conveyance. Determining the time it takes for a belt to complete one revolution is crucial for accurately measuring and controlling the production process. Currently, manual measurement using a mobile phone or stopwatch is often used to measure the time it takes for a belt to complete one revolution. However, this method presents numerous problems. First, manual measurement accuracy is low and susceptible to human factors, such as reaction time and operational errors. Second, it is inconvenient to operate, requiring dedicated personnel to perform the measurement, and the measurement process can interfere with normal production operations. Therefore, there is an urgent need for a device that can accurately and simply measure the time on a conveyor belt scale. Utility Model Content
