Problems solved by technology

[0002] The speedometer is a special equipment equipped with the electronic belt scale. It is a device used to detect the speed of the belt conveyor. Its detection accuracy directly affects the accuracy of the electronic belt scale. The pulse signal generator installed at one end of the speed measuring drum for shaft head speed measurement is light in weight and often bounces when measuring the belt speed, resulting in inaccurate speed measurement. In addition, the vibration of the belt and the bonded materials seriously affect the measurement accuracy and accuracy of the electronic belt scale. reliability
[0003] Most of the traditional belt speedometers use multi-stage gear transmission. Due to the large number of gears and the large meshing gap, the belt speed measurement is inaccurate, and even the counting data is lost, and the manufacturing cost is high; the two friction wheels used for speed measurement are installed on the same On the shaft, due to the vibration generated by the belt drive, the friction wheel will be bumped up, so that the data will be lost, and even the speed cannot be measured.
[0004] The existing connection device between the speed sensor of the electronic belt scale and the fixed shaft of the belt tail wheel is to add a connecting shaft with a smaller diameter at one end of the fixed shaft of the belt tail wheel, and then connect the connecting shaft with the drive shaft of the speed measuring sensor through a cylindrical joint Together, the middle of the cylindrical joint is provided with a channel for inserting the connecting shaft and the transmission shaft of the speed measuring sensor, and a screw hole is provided on one side for fastening the connecting shaft and the transmission shaft of the speed measuring sensor. This connecting device is not only structural Complicated and short-lived
