Abstract

Technical Field
[0001] This utility model relates to the field of sample preparation for waterproof materials, specifically a sample preparation device for testing waterproof materials. Background Technology
[0002] Waterproof materials consist of a surface waterproof coating and a waterproof substrate. When testing waterproof materials, multiple samples need to be prepared to test the waterproof effect under different conditions, hence the need for sample preparation.
[0003] In the current sample preparation process, the staff usually use a scraper to evenly apply the coating to the waterproof substrate. Since this method is done manually, uneven application is inevitable and difficult to detect, which can affect the conclusion of the waterproof test. Utility Model Content

[0007] As a further embodiment of this utility model: the scraper mechanism includes a threaded sleeve threaded to the outer periphery of the threaded rod and a sliding sleeve slidably connected to the outer periphery of the guide shaft, and a scraper is fixedly installed between the guide shaft and the sliding sleeve.
[0008] As a further improvement of this utility model: when the top of the sliding sleeve is aligned with the zero mark of the scale, the bottom of the scraper is aligned with the marking line.
[0009] As a further improvement of this invention, the diameter of the driving drive wheel is smaller than the diameter of the driven drive wheel.

[0016] 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.
[0017] Please see Figures 1-3 In this embodiment of the present invention, a sample preparation device for testing waterproof materials includes a worktable 1 with legs at the bottom. A drive mechanism is installed at the bottom of the worktable 1. A rotating disk 2 is connected to the output end of the drive mechanism. The rotating disk 2 is located at the top of the worktable 1. A threaded rod 4 is rotatably installed on one side of the top of the worktable 1 on the outer periphery of the rotating disk 2. A guide shaft 3 is fixedly installed on the other side of the top of the worktable 1 on the outer periphery of the rotating disk 2. A scraper mechanism is movably connected to the outer periphery of the guide shaft 3 and the threaded rod 4. The inner wall of the rotating disk 2 is engraved with marking lines 14, and the outer wall of the guide shaft 3 is engraved with scales 8.
[0018] In this embodiment: First, the waterproof substrate is placed in the inner cavity of the rotating disk 2. After the thickness of the waterproof substrate is placed, its top surface is flush with the marking line 14. That is to say, when preparing the sample, a substrate of uniform material and thickness should be selected to avoid inconsistencies in the substrate data of the reference group.
[0019] Calculate the required volume of waterproof coating (top area of substrate multiplied by coating thickness) by calculating the thickness of the waterproof coating, and then add the waterproof coating according to the calculation results.
[0020] Then, by rotating the threaded rod 4, the scraper mechanism moves downward under the guidance of the guide shaft 3 until the lowest end of the scraper mechanism moves to the position where the coating thickness is equal to the height of the waterproof substrate. Finally, the drive mechanism is started, which drives the rotating disk 2 to rotate. At this time, the scraper mechanism can evenly coat the waterproof coating to complete the sample preparation.
[0021] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The drive mechanism includes a rotary motor 10 mounted on the worktable 1 via a mounting bracket 9. The output shaft of the rotary motor 10 passes through the mounting bracket 9 and is connected to a drive drive wheel 11 via a coupling. The bottom end of the rotary disk 2 is coaxially connected to a driven drive wheel 13 via a concentric shaft. The driven drive wheel 13 is rotatably connected to the worktable 1 via a bearing. The drive drive wheel 11 and the driven drive wheel 13 are connected by a transmission belt 12. The diameter of the drive drive wheel 11 is smaller than the diameter of the driven drive wheel 13.
[0022] In this embodiment: by starting the rotary motor 10, the rotary motor 10 runs and drives the active transmission wheel 11 at its output end to rotate. At this time, the active transmission wheel 11 drives the driven transmission wheel 13 to rotate synchronously through the transmission belt 12. Since the diameter of the active transmission wheel 11 is smaller than the diameter of the driven transmission wheel 13, and the linear velocities of the active transmission wheel 11 and the driven transmission wheel 13 are equal, the angular velocity of the driven transmission wheel 13 is smaller than the angular velocity of the active transmission wheel 11. Therefore, a speed reduction transmission effect is achieved. The rotating driven transmission wheel 13 can drive the rotating disk 2 connected to its top through a concentric shaft to rotate. The rotating disk 2 synchronously drives the waterproof substrate and waterproof coating placed inside to rotate.
[0023] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The scraper mechanism includes a threaded sleeve 5 threaded to the outer periphery of the threaded rod 4 and a sliding sleeve 6 slidably connected to the outer periphery of the guide shaft 3. A scraper 7 is fixedly installed between the guide shaft 3 and the sliding sleeve 6.
[0024] In this embodiment: after the waterproof substrate and waterproof coating are added, the threaded rod 4 is rotated, which drives the threaded sleeve 5 to move in the up and down direction. At the same time, the sliding sleeve 6 slides up and down on the outer wall of the guide shaft 3 until the top of the sliding sleeve 6 moves to a certain scale and aligns with it. This scale is the thickness of the waterproof coating. Then the drive mechanism is started, which drives the rotating disk 2 to rotate. At this time, the scraper 7 can evenly apply the waterproof coating.
[0025] Please refer to this carefully. Figure 1 and Figure 3 When the top of the sliding sleeve 6 is aligned with the zero mark of the scale 8, the bottom of the scraper 7 is aligned with the marking line 14.
[0026] In this embodiment: This design allows the distance between the scraper 7 and the top surface of the waterproof substrate to be determined by the scale 8.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
