Firstly, everyone is already very familiar with electronic belt scales. They are automatic continuous measuring and weighing devices for materials conveyed by belt conveyors, and are also ideal equipment for industrial and mining enterprises to achieve automation of belt transportation measurement, long-distance data transmission, and production supervision.
Electronic belt scales have developed for a long time and have evolved into various types. From the perspective of the force transmission method of the scale frame, there are lever type and suspension type, and the fully suspended electronic belt scale is an important structural type.
What is a fully suspended electronic belt scale from the structure of the scale frame
The lever type belt scale uses the principle of lever force transmission for weighing, while the suspended belt scale uses direct force transmission for weight detection. The fully suspended belt scale is suspended on two crossbeams with four weighing sensors suspended to suspend the scale frame, without using leverage to transmit force, similar to a static platform scale. There are multiple sets of weighing rollers on the weighing bridge.
The multi roller fully suspended belt scale is a new type of scale frame, mainly composed of four weighing sensors and a scale frame installed with multiple rollers. Four weighing sensors suspend the scale frame at the four corners. During operation, when material is driven through the movable frame by a belt, the weight of the material is transmitted to the four weighing sensors through the rollers and scale frame, and then the material flow rate is displayed through a secondary instrument.
The fully suspended electronic belt scale has the following characteristics:
1. Simple structure: As can be seen from the introduction of the fully suspended belt scale above, besides the sensor, the fully suspended belt scale has no fulcrum or lever, greatly simplifying the structure.
2. Easy installation and debugging: The fully suspended belt scale has fewer mechanical structural components, and the suspended installation of weighing sensors requires fewer mechanical components and simpler installation processes.
3. High measurement accuracy: The fully suspended belt scale has no fulcrum, avoiding fulcrum errors;
Simplify the structure of the scale body and reduce the influence of mechanical components; Without support points and force transmission levers, weight is transmitted more directly and effectively to the weighing sensor, reducing force transmission errors caused by the connection of support points and spring plates;
The weighing sensor and weighing frame are connected by joint bearings, effectively eliminating the influence of lateral forces;
Four weighing sensors are distributed at the four corners of the suspended frame, and the measurement is not affected by the position of the material.
Sometimes the material on the belt is biased to one side, which does not affect the accuracy of the weighing.
4. Calibration is simpler: When calibrating a belt scale, the weights can be placed at any position on the scale frame without affecting the calibration results. Unlike belt scales with pivot points that require accurate placement of weights in designated positions, any deviation can affect the accuracy of calibration.
5. Good working performance: The fully suspended belt scale is a new type of structure that has shown good working performance in applications, but its limitations mainly lie in the high requirements for the inclination angle of the conveyor. Only conveyors with an inclination angle within 6 ° can achieve the ideal measuring effect.
The typical representative of the fully suspended electronic belt scale is the ICS-14 belt scale. Through many practical application cases in various industries of Guonuo Technology, it has been shown that after careful installation and debugging, as well as normal maintenance and calibration, its measurement performance is stable, high accuracy, and application precision is generally better than 0.5%. It can meet the high-precision measurement needs of port trade, production control, process supervision and other occasions.
