Description

Technical Field

[0001] This utility model relates to the field of sheet material testing technology, specifically to an online thickness measurement and control device for fiber-reinforced calcium silicate boards. Background Technology

[0002] Fiber-reinforced calcium silicate board is a new type of building material made from calcium silicate as the base material and reinforced with glass fiber, cellulose, and other fibers. Due to its lightweight, high strength, fire resistance, moisture resistance, sound insulation, and heat insulation properties, it is widely used in building partitions, ceilings, and external wall insulation. During the production process, the thickness of the fiber-reinforced calcium silicate board is dynamically measured in real time using a laser rangefinder, thus ensuring the stability and consistency of the board's quality.

[0003] During the processing of boards, uneven mixing and distribution of materials can lead to inconsistent board density, or wear and uneven pressure of the pressing rollers can cause local deformation of the board. Currently, in the process of measuring the thickness of boards, thickness gauges generally measure the thickness at a single point, resulting in a low coverage of measurement points and making it inconvenient to measure the thickness of the board comprehensively.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6This utility model discloses an online thickness measurement control device for fiber-reinforced calcium silicate board, including a roller conveyor belt 1 for conveying the fiber-reinforced calcium silicate board and a laser thickness gauge 2.

[0024] Specifically, the transmission assembly includes a rotating rod 7, a fixed shaft 8, and a strip frame 9. One end of the rotating rod 7 is fixedly connected to the output shaft of the drive motor 6, and the fixed shaft 8 is fixedly installed at the other end of the rotating rod 7. The fixed shaft 8 is slidably inserted into the inside of the strip frame 9, which is installed inside the bracket 3. The slider 4 is fixedly connected to the surface of the strip frame 9.

[0025] In this implementation scheme, the drive motor 6 is started, and the drive motor 6 drives one end of the rotating rod 7, causing the rotating rod 7 to rotate around one side of the output axis of the drive motor 6. At the same time, the other end of the rotating rod 7 drives the strip frame 9 to move to one side through the fixed shaft 8. Meanwhile, the fixed shaft 8 slides along the inner wall of the strip frame 9. Then the rotating rod 7 drives the fixed shaft 8 to rotate to the other side, and the fixed shaft 8 drives the strip frame 9 to move to the other side. At the same time, the strip frame 9 drives the slider 4 to reciprocate along the inner wall of the slide rail 5, and at the same time drives the laser thickness gauge 2 on the slider 4 to move horizontally, so that the laser thickness gauge 2 can detect multiple points of the plate.

[0026] Specifically, the cleaning device includes a housing 10, a cleaning brush 11, a rotating assembly, and a vacuuming assembly. The housing 10 is mounted on the roller conveyor belt 1. The cleaning brush 11 is mounted inside the housing 10 via the rotating assembly. Multiple cleaning brushes 11 are arranged in an array. The vacuuming assembly is mounted on the surface of the housing 10.

[0027] Specifically, the rotating assembly includes multiple rotating gears 12 and a rotating motor 13. The number of rotating gears 12 is matched with the number of cleaning brushes 11. Adjacent rotating gears 12 mesh with each other. The rotating motor 13 is mounted on the surface of the housing 10 via a flange and is connected to one of the rotating gears 12.

[0028] In this embodiment, the control motor 13 is started, and the output shaft of the motor 13 drives a connected gear 12 to rotate. Simultaneously, the gear 12 drives multiple gears 12 to rotate, and each gear 12 drives a corresponding cleaning brush 11 to rotate. When the board passes over the cleaning brush 11, the brush 11 removes the adhering debris and impurities from the board.

[0029] Specifically, the dust collection assembly includes a collection box 14, an exhaust fan 15, and a dust collection hood 16. The collection box 14 is fixedly installed on the surface of the housing 10. The exhaust fan 15 is fixedly connected to the top of the collection box 14. A filter screen is provided at the connection between the exhaust fan 15 and the collection box 14. The dust collection hood 16 is fixedly installed on one side of the housing 10. The opening of the housing 10 faces the roller conveyor belt 1. The collection box 14 is connected to the dust collection hood 16 through a connecting pipe.

[0030] In this embodiment, the exhaust fan 15 is started, and the exhaust fan 15 draws air to form a negative pressure inside the dust collection hood 16. Then, the impurities cleaned by the cleaning brush 11 are sucked into the dust collection hood 16, and then drawn into the pull-out box of the collection box 14 through the connecting pipe for cleaning and collection of debris.

[0031] Specifically, the adjustment device includes a guide frame 17, a self-locking motor 18, an adjustment gear 19, and a fixed rack 20.

The adjustment gear 19 is fixedly connected to the output shaft of the self-locking motor 18 and meshes with the fixed adjustment gear.

[0032] In this embodiment, when the thickness of the sheet material is different, the self-locking motor 18 is started, and the self-locking motor 18 drives the adjusting gear 19 to rotate, so that the adjusting gear 19 moves along the surface of the fixed rack 20. At the same time, the self-locking motor drives the cover 10 to move, so that the cover 10 slides along the inner side wall of the guide frame 17 through the guide block, so that the height of the cover 10 can be adjusted according to the thickness of the sheet material, which can adapt to sheet materials of different thicknesses.

[0033] The working principle and usage process of this utility model are as follows: In use, the fiber-reinforced calcium silicate board is placed on the roller conveyor belt 1, which then transports the board. The board then passes through a cleaning device; two cleaning devices at the top and bottom of the roller conveyor belt 1 clean both sides of the board. Simultaneously, the rotating motor 13 is started, and its output shaft drives a connected rotating gear 12 to rotate. This rotating gear 12 drives multiple rotating gears 12 to rotate, and each rotating gear 12 drives a corresponding cleaning brush 11 to rotate. When the board passes the cleaning brush 11, the brush sweeps away the adhering debris and impurities. Then, the exhaust fan 15 is started, creating a negative pressure inside the dust collection hood 16. The impurities swept by the cleaning brush 11 are then sucked into the dust collection hood 16 and then drawn into the pull-out box of the collection box 14 through a connecting pipe for collection of debris and impurities.

[0034] The roller conveyor belt 1 continues to transport the cleaned sheet material to the bottom of the laser thickness gauge 2. Then, the two laser thickness gauges 2 at the top and bottom of the roller conveyor belt 1 test the thickness of the sheet material. At the same time, the drive motor 6 is started. The drive motor 6 drives one end of the rotating rod 7, causing the rotating rod 7 to rotate around one side of the output axis of the drive motor 6. At the same time, the other end of the rotating rod 7 drives the strip frame 9 to move to one side through the fixed shaft 8. Meanwhile, the fixed shaft 8 slides along the inner wall of the strip frame 9. Then, the rotating rod 7 drives the fixed shaft 8 to rotate to the other side. At the same time, the fixed shaft 8 drives the strip frame 9 to move to the other side. Meanwhile, the strip frame 9 drives the slider 4 to reciprocate along the inner wall of the slide rail 5. At the same time, it drives the laser thickness gauge 2 on the slider 4 to move horizontally, so that the laser thickness gauge 2 can detect multiple points on the sheet material.
