Description

Technical Field

[0001] This utility model relates to the field of scraper fineness gauge calibration technology, and in particular to a scraper fineness gauge calibration device. Background Technology

[0002] A scraper fineness gauge is an instrument used to detect the uniformity of solid particle distribution in a liquid. It is widely used in industries such as papermaking, chemicals, and food to assess the fineness and dispersibility of raw materials. Its working principle involves a scraper creating grooves in the liquid, and the particle fineness is determined based on the depth of these grooves. To ensure the accuracy and consistency of the scraper fineness gauge during measurement, it needs to be calibrated periodically.

[0003] Existing methods for calibrating scraper fineness gauges mostly involve manual adjustment and measurement, which is not only time-consuming but also difficult to guarantee accuracy. Common calibration methods rely on manually adjusting the scraper's tilt, position, and scale, judging the gauge's working condition through visual inspection and manual measurement. This method is easily affected by human factors during calibration, leading to inaccurate measurement data, and is also cumbersome and inefficient. Furthermore, traditional calibration equipment often lacks precise testing of important parameters such as the scraper fineness gauge's flatness and scale, making it difficult to meet increasingly stringent accuracy requirements.

[0004] Therefore, it is very necessary to invent a device for calibrating a scraper fineness gauge. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a scraper fineness gauge calibration device, which solves the issues of existing scraper fineness gauge calibration structures still requiring extensive manual intervention, resulting in poor accuracy of the information obtained, and complex calibration processes. The scraper fineness gauge calibration device includes a calibration workbench, a calibration fixture, a scraper fineness gauge, a drive housing, a calibration screw, a drive motor, and an identification structure. The calibration fixture is mounted at the front end of the calibration workbench surface, and the scraper fineness gauge is placed on the calibration fixture. The drive housing is mounted at the rear end of the calibration workbench surface. The calibration screw is mounted at the front of the drive housing, and the drive motor is fixedly mounted on the top of the drive housing, with its output shaft connected to the calibration screw. The identification structure is slidably mounted at the front of the drive housing and engages with the calibration screw.

[0006] The calibration fixture includes a front-to-back moving structure, a horizontal moving seat, a fine-tuning drive screw, a calibration placement plate, and a positioning block. The front-to-back moving structure is fixedly installed on the front end of the calibration workbench surface, and the horizontal moving seat is slidably installed on the front-to-back moving structure. The fine-tuning drive screw is installed on the horizontal moving seat, and the calibration placement plate is slidably installed on the fine-tuning drive screw. The positioning block is fixedly installed on the surface of the calibration placement plate.

[0007] The calibration structure includes a support base, a connecting base, a laser generator, a flatness calibration laser head, and a scale calibration structure. The support base is slidably mounted on the front of the drive housing and engages with the calibration screw. The connecting base is fixedly mounted on the front end of the support base, and the laser generator is fixedly mounted inside the connecting base. The flatness calibration laser head is fixedly mounted on the bottom end of the laser generator. The scale calibration structure is fixedly mounted on one side of the connecting base.

[0008] The calibration placement plate inside the calibration fixture can reciprocate in multiple directions through a forward and backward moving structure, a horizontal moving seat, and a fine-tuning drive screw; the fine-tuning drive screw can drive the calibration placement plate to reciprocate in the direction of the scraper fineness gauge groove; the positioning block is made of two long strip-shaped metal blocks, and the size of the positioning block matches the scraper fineness gauge.

[0009] The overall identification structure can reciprocate vertically via the calibration screw and drive motor. The flatness calibration laser head uses a laser flatness detection device, which acts on the scraper fineness gauge through dual-laser beam interferometry. The scale calibration structure uses a high-definition macro camera and can be wirelessly connected to an external computer, and is equipped with AI image recognition technology. An auxiliary light source is provided on one side of the scale calibration structure.

[0011] 1. The calibration fixture of this utility model has the following functions: ① Ensuring calibration stability: The calibration fixture precisely fixes the scraper fineness gauge through the calibration placement plate and positioning block, preventing it from shifting or shaking during the calibration process, thus ensuring the accuracy and repeatability of the measurement data; ② Improving calibration accuracy: Through the front and rear moving structure, horizontal moving seat, and fine-tuning drive screw, the calibration fixture can be finely adjusted in multiple directions to align the groove direction of the scraper fineness gauge with the calibration equipment, improving measurement accuracy and avoiding measurement deviations due to positional errors; ③ Cooperating with calibration equipment to complete automated testing: The calibration fixture provides a stable support platform for the entire calibration process, enabling the laser measurement and scale calibration structure to accurately focus and collect data, while reducing external environmental interference and improving the automation level and testing efficiency of the calibration device.

[0012] 2. The identification structure of this utility model has the following functions: ① Detecting the flatness of the scraper fineness gauge: The identification structure emits a laser through a flatness verification laser head and uses a dual-laser beam interferometry method to perform high-precision detection of the flatness of the scraper fineness gauge, ensuring that its surface meets the standard requirements; ② Verifying the scale accuracy of the scraper fineness gauge: Through a high-definition macro camera in the scale verification structure, combined with AI image recognition technology, the scale on the scraper fineness gauge is automatically identified and measured to ensure the accuracy of the scale, and the data can be wirelessly transmitted to an external computer for analysis and storage; ③ Completing automated detection: The identification structure meshes with the verification screw and is controlled by a drive motor to achieve reciprocating movement in the vertical direction, enabling the laser head and camera to perform comprehensive detection of the scraper fineness gauge in sequence, improving verification efficiency and automation.

[0013] 3. The overall design of this utility model's scraper fineness gauge calibration device, through high-precision automation technology, ensures that the scraper fineness gauge reaches a standard working state before use, guaranteeing the accuracy and consistency of measurement results. This device utilizes automated calibration functions, a flatness calibration laser head and laser interferometry technology for high-precision flatness detection, a high-definition macro camera combined with AI image recognition for scale calibration, and multi-directional adjustment functions of the calibration fixture. This enables efficient and accurate calibration of the scraper fineness gauge. Compared to traditional manual operation, the automated process reduces human error, improves calibration efficiency and accuracy, and possesses strong versatility, adapting to different models of scraper fineness gauges, significantly enhancing the stability and reliability of the calibration process.
