Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of measurement, and in particular relates to a contact type on-line thickness measuring device. Background Art
[0002] In the production process of sheet materials such as flexible films and waterproof coiled materials, in order to ensure the quality and performance stability of products, it is necessary to detect the thickness of the sheet materials in real time. In the prior art, a contact type thickness gauge is usually used to detect the thickness of the sheet materials. However, such a device can only detect at a single point in a fixed position, which results in only being able to detect the thickness of a certain position of the sheet material. If multi-point detection is required, more thickness gauges can only be used, resulting in a significant increase in equipment costs. Although the ray type thickness gauge can perform multi-point measurement, the monitoring accuracy will be affected by environmental factors, and the detection accuracy will also be reduced by the influence of different materials and uniformity changes of the measured object. Moreover, rays will also pose a hazard to human health. Content of the Utility Model
