Electronic belt scale is an online dynamic weighing device composed of weighing sensors, speed sensors, instruments, and scale frames. The scale frame is the force transmission device of the belt scale. Simplifying the structure of the scale frame, reducing weight, and optimizing the structure are important measures to improve the measurement accuracy and stability of the belt scale, and reduce installation and maintenance workload.
The scale frame structure of the electronic belt scale adopts a modular design structure, which can simplify the structure and installation design of the belt scale, achieve high-precision and high stability measurement requirements, reduce installation and maintenance workload, and is a structural simplification and technological innovation for dynamic measurement of belt transported materials.
It is conducive to making the belt scale play a greater role and value, and meeting the application needs of high-precision and easy installation and maintenance of the belt scale.
Technical structural characteristics of modular electronic belt scale:
(1) The two rollers are designed as an independent measuring element, and the two sets of measuring rollers are used as a single measuring unit. A set of measuring modules (units) uses four high-precision weighing sensors to support the measuring rollers, which can improve the accuracy of weight signal acquisition.
(2) Two or more sets of measuring modules can be used at equal distances, and the measuring modules are independent of each other without crossbeams or levers. When one measuring module cannot work, other measuring modules can complete the measurement normally, improving measurement stability.
(3) The measurement module adopts high-precision digital weighing sensors with strong anti-interference ability and long signal transmission distance. The force bearing surface of the sensor is close to the installation surface of the sensor, reducing the installation position. This can effectively compensate for the influence of fulcrum friction torque and belt offset load on the displacement of the measuring roller, greatly improving weighing accuracy, environmental applicability, and stability during use.
(4) The modular electronic belt scale structure makes installation simpler and more convenient. The installation or replacement of the measuring module only requires removing the components, connecting and fixing them to the scale frame with bolts or sensor brackets, positioning them, and then welding them firmly and reliably. Reduced the difficulty of designing and using the integral belt scale, and made on-site maintenance and replacement convenient.
(5) The modular electronic belt scale has higher flexibility and scalability, and can be installed in multiple groups according to the user's requirements for measurement accuracy, forming a single end or multi-stage measurement mechanism. When users need to extend the weighing area and add measuring modules due to actual process changes on site, there is no need to purchase and install a brand new belt scale. Instead, one or more measuring modules can be added according to the spacing between the rollers, forming an integrated measuring mechanism with multiple measuring modules, which improves the flexibility of on-site application transformation.
Through practical application, it has been shown that modular electronic belt scales have a simple structure, compact size, higher measurement accuracy and stability, simple and convenient transportation and installation, low maintenance workload, and stronger adaptability to application environments.
