What are the problems with weightless scales that need improvement?
With the development of modern industry, measurement methods are gradually developing. The measuring tools used in the early days were belt scales, spiral scales and accumulating scales. Hyundai introduced a new weightless scale for measuring tools. Weightlessness scales have replaced earlier scales and have been more and more widely used in various industries. The characteristic of weightlessness scale is that it can continuously and accurately measure, which is also something that early scales could not do. Its working principle is to measure according to the change of material weight during use. The weightlessness scale will have control and processing functions during use, and the control instrument of the equipment will use the weight change per unit time as instant data, which can be compared with the target data. If the actual amount is insufficient during operation, the rotation speed can be changed, and the target can be as close as possible. The sensor feels the change in weight, but the signal transmitted by the sensor during this period may be inaccurate. In order to prevent this situation, the single-screw weightlessness scale has set up the function of replenishment delay in the control instrument, so that the time calculation can start from the time the valve is closed. During this period, the feeder can keep the frequency constant, that is, during the period from the beginning to the end, the feeding motor will maintain the frequency before feeding. This can make the weightlessness scale in a static control state in the process, and make it in a fixed frequency operation state. There are many reasons for the problems of the weightless scale. For example, the fan in the workshop will affect its accuracy. During the operation of the entire workshop, workshop noise is a common situation, so if the noise is too loud, it will also interfere with the accuracy of the weightlessness scale. During the operation of the manufacturer, it is impossible to ensure that only the weightless scale is inside the workshop, and the vibration generated by other machines in motion will also interfere with the accuracy measurement to a certain extent. The above are the possible problems of the weightless scale, and also the problems that need to be paid attention to in the use process.
