Technical Field
[0001] This utility model relates to the field of belt scale technology, and in particular to an installation mechanism for converting a belt scale into a high-precision belt scale. Background Technology
[0002] Belt scales, as efficient dynamic metering devices, are widely used in industries such as steel, cement, chemical, and power to monitor material flow and cumulative weight in real time, helping companies optimize production processes, improve efficiency, and reduce costs. Currently, there are hundreds of thousands of belt scales in use on the market. However, due to limitations in their structural design, manufacturing processes, and environmental adaptability, they generally suffer from low accuracy and insufficient stability, making it difficult to meet the demands for high-precision metering.
[0003] The main factors affecting the accuracy of belt scales include:
[0004] (1) Manufacturing error of parts: The manufacturing of traditional belt scales relies on riveting and welding process, and the processing accuracy is difficult to guarantee, resulting in insufficient rigidity of the scale frame structure or installation deviation;
[0005] (2) Environmental interference: Extreme temperatures, humidity, vibrations, etc. can easily cause deformation of the weighing frame or supporting structure, further affecting the weighing stability;
[0006] (3) Belt operation problems: After long-term use, belt wear, aging or uneven tension may cause belt deviation, resulting in measurement fluctuations.
[0007] There is an urgent need to upgrade existing belt scales, but traditional methods require replacing the entire structure, which is costly and time-consuming. In addition, the production of new belt scales still faces bottlenecks such as high processing difficulty and difficulty in improving accuracy. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] See attached document Figure 1 This embodiment provides an installation mechanism for converting a belt scale into a high-precision belt scale, including a frame 1, a support plate 2 and a cover plate 3 on the frame 1, a roller assembly 4 on the support plate 2, the support plate 2 moving along the height direction of the frame 1, a height adjustment component 5 between the support plate 2 and the cover plate 3, adjusting the height of the support plate 2 and thus the height of the roller assembly 4 by adjusting the height adjustment component 5, the cover plate 3 moving along the width direction of the frame 1, the cover plate 3 being divided into two groups, the first group of cover plates 3 having a base plate 6 below it, the base plate 6 moving along the length direction of the frame 1, the base plate 6 being fixed to the frame 1 by a second screw, the front and rear positions of the roller assembly 4 being adjusted by moving the base plate 6, and then the base plate 6 being fixed to the frame 1 by the second screw, the second group of cover plates 3 having a load cell 7 between it and the base plate 6, the second group of cover plates 3 being fixed to the load cell 7 by a first screw, the load cell 7 being fixed to the base plate 6, the first group of cover plates 3 being fixed to the base plate 6 by the first screw. The left and right positions of the idler assembly 4 are adjusted by moving the cover plate 3, and then the cover plate 3 is fixed to the base plate 6 or the weighing sensor 7 by the first screw. When the idler assembly 4 is subjected to a downward force, the support plate 2 can be moved downward, so that the downward force on the idler assembly 4 can be transmitted to the weighing sensor 7. Since the source of the force on the idler assembly 4 is the gravity of the material, the weighing sensor 7 can determine the actual weight of the material based on the detected pressure, thereby achieving the purpose of weighing the material.
