[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a filter cloth thickness detection device, including a mounting plate 1, an ultrasonic ranging probe 2, a support plate 3, a base plate 4, a magnet strip 5, a metal positioning plate 6, a handle 7, an electric telescopic rod 8, a movable plate 9, a gear cylinder 10, a middle plate 11, a stabilizing hole 12, a movable column 13, a support spring 14, an inner frame 15, and a flat roller 16. The ultrasonic ranging probe 2 is mounted at the top center of the mounting plate 1. The support plate 3 is fixed to the middle of the front of the vertical part of the mounting plate 1. The base plate 4 is mounted at the top of the support plate 3. A magnet strip 5 is fixed to the end of the top surface of the support plate 3 on one side of the base plate 4. The top surface of the magnet strip 5 is in contact with the bottom surface of the metal positioning plate 6. A handle 7 is fixed. An electric telescopic rod 8 is installed on one side of the bottom of the mounting plate 1. A movable plate 9 is fixed to the end of the electric telescopic rod 8. The bottom surface of the movable plate 9 is in contact with the bottom of the mounting plate 1. The top surface of the horizontal part of the movable plate 9 is connected to the bottom of the gear cylinder 10. The gear cylinder 10 is rotatably installed at the bottom of the vertical part of the mounting plate 1 via a rotating shaft. The front side of the top of the gear cylinder 10 is connected and fixed to the bottom of the middle plate 11. A stabilizing hole 12 is opened in the horizontal part of the top of the middle plate 11. A movable column 13 is installed through the stabilizing hole 12. A support spring 14 is fixed between the top of the movable column 13 and the top surface of the middle plate 11. An inner frame 15 is fixed to the bottom of the movable column 13. A leveling roller 16 is rotatably installed inside the inner frame 15.

[0021] In this example, the centers of the ultrasonic ranging probe 2, the substrate 4, the gear cylinder 10, and the middle plate 11 are on the same vertical plane. The ultrasonic ranging probe 2 is symmetrically distributed about the center of the substrate 4. The above structural design enables the ultrasonic ranging probe 2 to be stably aligned with the filter cloth at the top center of the substrate 4, and the center of the top surface of the substrate 4 is used as the reference point to ensure the accuracy of the measurement.

[0022] The support plate 3, substrate 4, magnet strip 5 and metal positioning plate 6 are all arc-shaped. The frontal width of magnet strip 5 is not less than the frontal width of substrate 4, and the frontal width of magnet strip 5 is less than the frontal width of metal positioning plate 6. The above structural design enables metal positioning plate 6 to be stably adsorbed and attached to magnet strip 5, stably positioning one end of filter cloth, and ensuring stable attachment of filter cloth to the surfaces of support plate 3, substrate 4 and magnet strip 5.

[0023] The electric telescopic rod 8 is symmetrically distributed about the center of the movable plate 9. The toothed structure on the top surface of the horizontal part of the movable plate 9 is meshed with the bottom end of the gear cylinder 10. The center of the gear cylinder 10 coincides with the center of the circle where the arc edge of the support plate 3 is located. The above structural design enables the electric telescopic rod 8 to drive the movable plate 9 to slide horizontally and linearly along the bottom of the mounting plate 1. When the movable plate 9 is in linear displacement, it can stably drive the gear cylinder 10, the middle plate 11 and the leveling roller 16 to rotate stably by means of the meshing connection. When stationary, it can also lock the position of the gear cylinder 10, the middle plate 11 and the leveling roller 16 by means of the toothed meshing.

[0024] The side view of the middle plate 11 is "L" shaped. The rear side of the vertical part of the middle plate 11 is in contact with the front side of the middle plate 11, and the rear side of the top of the middle plate 11 is in contact with the front side of the vertical part of the mounting plate 1. The above structural design provides a stable mounting base for the movable column 13, the support spring 14, the inner frame 15 and the leveling roller 16, and improves the stability of the middle plate 11 when rotating and stationary.

[0025] The front and side views of the movable column 13 are both "T" shaped. The movable column 13 is slidably connected to the stabilizing hole 12. The movable column 13 is symmetrically distributed about the center of the flattening roller 16. The above structural design enables the movable column 13 to provide a stable mounting base for the support spring 14 and to stably slide and compress the support spring 14 along the stabilizing hole 12, ensuring that the flattening roller 16 can stably compress filter cloths of different thicknesses.

[0026] Working principle: When in use, hold the handle 7 to separate the metal positioning plate 6 from the magnet strip 5, place one end of the filter cloth on the surface of the magnet strip 5, and reposition the metal positioning plate 6 and the magnet strip 5 so that the metal positioning plate 6 and the magnet strip 5 clamp and fix one end of the filter cloth.

[0027] Then, the leveling roller 16 is raised, and the movable column 13 slides vertically upward along the stabilizing hole 12, stretching the support spring 14. The support spring 14 is a rigid spring with a certain stiffness coefficient, which provides elastic force when stretched, allowing the filter cloth to pass under the leveling roller 16 and be laid on the top surface of the support plate 3. Then, the leveling roller 16 is lowered. Under the elastic force of the support spring 14, the bottom end of the leveling roller 16 is stably attached to the surface of the filter cloth, and the filter cloth is pressed against the surface of the substrate 4. Then, the symmetrically distributed electric telescopic rods 8 are controlled to extend. Figure 1The electric telescopic rod 8 extends and pushes the movable plate 9 to move horizontally to the right. The movable plate 9 drives the gear cylinder 10 to rotate counterclockwise with the middle plate 11 and the leveling roller 16 through the meshing connection. During the rotation, the leveling roller 16 evenly squeezes and spreads the filter cloth on the surface of the support plate 3. When the rotation angle of the leveling roller 16 is appropriate, the electric telescopic rod 8 is stopped and the movable plate 9 is locked. The movable plate 9 fixes the position of the gear cylinder 10, the middle plate 11 and the leveling roller 16 through the toothed engagement. Under the elastic force of the support spring 14, the leveling roller 16 stably squeezes and fixes the other end of the filter cloth. Then the ultrasonic ranging probe 2 can be activated to measure the position data of the top surface of the filter cloth that has been evenly spread directly above the substrate 4. The data is compared with the reference point data of the center of the top surface of the substrate 4 to obtain the filter cloth thickness. This is the working principle of the filter cloth thickness detection device.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
