[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A fire retardant coating detection sample preparation device includes a base plate 1, a movable plate 2 is arranged above the base plate 1, and the movable plate 2 is a hollow structure, a plurality of fine holes 7 are opened on the bottom surface of the movable plate 2, the movable plate 2 is connected to the base plate 1 through a sliding structure, a storage box 5 is arranged on one side of the base plate 1, and the fire retardant coating is accumulated in the storage box 5, a feeding component is arranged on the movable plate 2, and a control component is arranged on the base plate 1.

[0021] Reference Figure 1-3 The sliding structure includes two sliders 3 and two slide bars 4. The two sliders 3 are respectively fixed at the two ends of the moving plate 2, and the two slide bars 4 are fixed on the bottom plate 1. The two sliders 3 are respectively slidably connected to the two slide bars 4. When the moving plate 2 moves, the two sliders 3 and the two slide bars 4 play a role in limiting and guiding the movement of the moving plate 2.

[0022] Reference Figure 1-3 The feeding assembly includes a sealing cylinder 8, a sliding plug 9, a spring 10, two mounting tubes 11, two check valves 12 and a connecting rod 13. The sealing cylinder 8 is fixed on the top surface of the movable plate 2. The sliding plug 9 is sealingly and slidingly connected to the inner surface of the sealing cylinder 8. One end of the spring 10 is connected to the inner surface of the sealing cylinder 8, and the other end is connected to the sliding plug 9. One end of the connecting rod 13 is fixed to the sliding plug 9, and the other end extends to the outside of the sealing cylinder 8. One end of the two mounting tubes 11 is connected to the sealing cylinder 8. The two check valves 12 are respectively installed on the two mounting tubes 11, the other end of one of the mounting tubes 11 is connected to the storage box 5, and the other end of the other mounting tube 11 is connected to the inside of the movable plate 2. Since the flow limiting directions of the two check valves 12 are opposite, specifically, one of the check valves 12 restricts the airflow to only enter the sealing cylinder 8, and the other check valve 12 restricts the airflow to only flow out of the sealing cylinder 8, so when the sliding plug 9 moves toward one end of the sealing cylinder 8, the sealing cylinder 8 can perform an extraction action, and when the sliding plug 9 moves toward the other end of the sealing cylinder 8, the sealing cylinder 8 can perform a discharge action. Based on the above process, along with the reciprocating movement of the movable plate 2, the sealing cylinder 8 can continuously extract the fire-retardant coating in the storage box 5 and discharge the fire-retardant coating into the interior of the movable plate 2. After the fire-retardant coating enters the interior of the movable plate 2, it will flow onto the substrate through a number of fine holes 7. A scraper 6 is also provided on the bottom surface of the movable plate 2. The scraper 6 can evenly scrape the fire-retardant coating that flows onto the substrate onto the substrate, thereby realizing the function of automatic sample preparation without manual coating.

[0023] Reference Figure 1-3 The control component includes an arc plate 14 and two fixed rods 15. One end of the two fixed rods 15 is fixed on the bottom plate 1, and the other end is fixedly connected to the two ends of the arc plate 14. The arc plate 14 is located above the movable plate 2. During the movement of the movable plate 2, the end of the connecting rod 13 located outside the sealing cylinder 8 will periodically contact the arc plate 14. When the end outside the sealing cylinder 8 contacts the arc plate 14, the arc plate 14 will squeeze the connecting rod 13, so that the connecting rod 13 drives the sliding plug 9 to move. When the connecting rod 13 is separated from the arc plate 14, the sliding plug 9 will reset under the action of the spring 10. In this way, during the reciprocating movement of the movable plate 2, the sliding plug 9 will reciprocate inside the sealing cylinder 8.

[0024] Reference Figure 1-3 The mounting pipe 11 is a hose to facilitate the movement of the movable plate 2.

[0025] Reference Figure 1-3 The flow limiting directions of the two check valves 12 are opposite. Specifically, one of the check valves 12 limits the airflow to only enter the sealing tube 8, and the other check valve 12 limits the airflow to only flow out of the sealing tube 8.

[0026] The specific working principle of the utility model is as follows:

[0027] When the fire retardant coating detection sample preparation device proposed by the utility model is in use, the staff injects the fire retardant coating to be detected into the storage box 5, and then places the substrate on the top surface of the bottom plate 1. Then, the staff pulls the movable plate 2 to make the movable plate 2 reciprocate above the bottom plate 1. During the movement of the movable plate 2, the end of the connecting rod 13 located outside the sealing cylinder 8 will periodically contact the arc plate 14. When the end outside the sealing cylinder 8 contacts the arc plate 14, the arc plate 14 will squeeze the connecting rod 13, so that the connecting rod 13 drives the sliding plug 9 to move. When the connecting rod 13 is separated from the arc plate 14, the sliding plug 9 will reset under the action of the spring 10. In this way, during the reciprocating movement of the movable plate 2, the sliding plug 9 will reciprocate inside the sealing cylinder 8. Due to the limiting flow direction of the two check valves 12 On the contrary, specifically, one of the check valves 12 restricts the airflow to only enter the sealing cylinder 8, and the other check valve 12 restricts the airflow to only flow out of the sealing cylinder 8, so when the sliding plug 9 moves toward one end of the sealing cylinder 8, the sealing cylinder 8 can perform an extraction action, and when the sliding plug 9 moves toward the other end of the sealing cylinder 8, the sealing cylinder 8 can perform a discharge action. Based on the above process, along with the reciprocating movement of the movable plate 2, the sealing cylinder 8 can continuously extract the fire-retardant coating in the storage box 5 and discharge the fire-retardant coating into the interior of the movable plate 2. After the fire-retardant coating enters the interior of the movable plate 2, it will flow onto the substrate through a number of fine holes 7. A scraper 6 is also provided on the bottom surface of the movable plate 2. The scraper 6 can evenly scrape the fire-retardant coating that flows onto the substrate onto the substrate, thereby realizing the function of automatic sample preparation without manual coating.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
