Description

Technical Field

[0001] This utility model relates to the field of laser diameter measuring instrument technology, and more specifically, to a high-precision laser diameter measuring instrument for rolling mills with auxiliary shielding. Background Technology

[0002] In modern industrial production, rolling mill rolls, as important forming equipment components, are widely used in various industries such as steel, non-ferrous metals, papermaking, and rubber. The diameter accuracy of the rolling mill rolls has a crucial impact on the quality and performance of the products. For example, in the steel industry, deviations in the rolling mill roll diameter directly lead to uneven steel thickness, affecting the strength and surface quality of the steel. In the papermaking industry, inconsistent rolling mill roll diameters result in uneven paper thickness, affecting the flatness and printability of the paper. Therefore, accurate measurement of the rolling mill roll diameter is of great significance for ensuring product quality, optimizing production processes, and reducing production costs. Currently, there are various devices on the market for measuring the rolling mill roll diameter. Among them, laser diameter gauges have been widely used due to their advantages such as non-contact operation, high precision, and fast measurement speed.

[0003] Existing high-precision laser diameter measuring instruments for rolls have the measuring cavity directly exposed during use. However, industrial production sites often have various complex lighting environments, such as workshop lighting and strong light reflections from equipment operation. These external light sources can interfere with the laser signal emitted by the laser diameter measuring instrument, causing deviations in the signal received by the receiver and affecting the accuracy of the measurement results. Therefore, a high-precision laser diameter measuring instrument for rolls with auxiliary shielding is proposed. Utility Model Content
