Description

TECHNICAL FIELD

[0001] The application relates to the technical field of thickness measuring devices, in particular to an online thickness measuring device. BACKGROUND

[0002] As a key equipment in the field of industrial automation, the online thickness measuring device is mainly used for real-time monitoring of the thickness parameters of materials in a continuous production process, such as metal plates, plastic films, high-temperature rolled materials and the like. Such a device usually adopts a non-contact measuring principle, and the optical or electromagnetic sensors are symmetrically arranged above and below the material transmission path, and the thickness value is calculated by using the change of the transmitted signal. The core advantage of the device is that the quality monitoring can be realized without interrupting the production process, which plays an important role in improving product consistency and reducing the waste rate.

[0003] However, although there are various devices for measuring the thickness of materials, there are still some problems, for example, in the online thick piece thickness measuring device disclosed in the publication No. CN222733491U, the thickness variation degree can be amplified through the mutual cooperation between the internal structures of the double-range assembly, so that the workers can clearly understand the thickness variation degree of the workpiece, and the judgment is facilitated. However, in the technical solution and most of the current technical solutions, the current thickness measuring device mostly needs a support frame to support it, and the mechanical stability of the support frame directly affects the measurement accuracy. The current mainstream design adopts a fine adjustment structure composed of a sliding groove and a locking screw. When operating, the screw needs to be repeatedly screwed to adjust the position of the support frame, and then fixed through the friction force of the screw thread.

[0004] Although the above adjustment method can quickly realize the fine adjustment of the position of the sensor, the assembly gap between the sliding groove and the screw cannot be completely eliminated after locking, which causes the sensor support frame to produce micron-level displacement under the action of vibration or external force. When the measurement environment has mechanical vibration, this gap may further amplify the displacement amplitude, causing a large error in thickness measurement. Moreover, when the support frame is deflected, the thickness measurement error will also be amplified synchronously, especially in high-temperature and vibration working conditions, this structural defect is more significant, which causes the sensor to be out of alignment, and seriously affects the measurement accuracy.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an online thickness measuring device. CONTENT OF THE UTILITY MODEL
