[0039] By setting the above structure, the mounting plate 2 is pressed downward, so that the piston rod 221 retracts into the piston groove 22, and then the detection disk 21 is inserted between the clamping sliders 41 on both sides along the surface of the mounting plate 2. During this process, the side wall of the detection disk 21 will squeeze the clamping slider 41, so that the clamping slider 41 retracts into the clamping shell 4. Finally, when the detection disk 21 is fully inserted, the rebound effect of the first spring 42 will make the detection disk 21 be clamped and fixed between the clamping sliders 41 on both sides, thereby effectively improving the stability of the detection.

[0041] It should be noted that a filter is provided at the port of the air guide groove 223 close to the collecting groove 51 , and the filter is used to prevent dust in the collecting groove 51 from being sucked into the piston groove 22 .

[0042] By setting the above structure, after the pressure on the mounting plate 2 is released, the rebound effect of the second spring 222 will cause the mounting plate 2 to move up and reset, so that the detection disk 21 will move to the bottom of the spray box 31, and at this time, the upward movement of the piston rod 221 will generate suction at the bottom of the inner cavity of the piston groove 22, so that the airflow in the collecting groove 51 enters the piston groove 22 along the air guide groove 223, so that the collecting groove 51 is in a negative pressure state, so that the airflow on the surface of the detection disk 21 passes through the leakage hole 211 and enters the collecting groove 51, thereby realizing the cleaning of the detection disk 21 and ensuring the detection accuracy; when the waterproof coating leaks, the water flow will slide along the leakage hole 211, the collecting groove 51 and the drip groove 511 into the test paper chuck 5, so that the moisture detection test paper in the test paper chuck 5 changes color, thereby completing the permeability detection of the waterproof coating.

[0043] Reference Figure 1-Figure 3 , Figure 6 and Figure 8 The feeding part includes a feeding tray 6, which is fixed on the top of the detection box 1. A coating bin 61 and a water spray bin 62 are respectively provided on both sides of the inner cavity of the feeding tray 6. The side wall of the coating bin 61 is fixed and connected with a feeding pipe 611. The side wall of the water spray bin 62 is fixed and connected with a water supply pipe 621. A feeding ring 63 is rotatably sleeved on the outer wall of the driving shaft 3. The feeding ring 63 is fixedly connected to the top of the inner cavity of the detection box 1. A feeding trough 631 is provided in the inner cavity of the driving shaft 3. The feeding ring 63 is connected with the feeding trough 631. The bottom end of the feeding trough 631 is connected with the inner cavity of the spray box 31. Spray heads 311 are provided at equal intervals at the bottom of the spray box 31. Both sides of the top of the inner cavity of the detection box 1 are fixed. A material guide pipe 64 is fixedly connected, and the top ends of the material guide pipes 64 on both sides are connected to the inner cavities of the paint bin 61 and the water spray bin 62 respectively, and solenoid valves are provided in the material guide pipes 64 on both sides. The solenoid valves are used to adaptively open the material guide pipes 64 on the corresponding sides, which improves the convenience of use. Feed pipes 632 are fixed and connected on both sides of the feed ring 63, and the feed pipes 632 are fixed and connected to the material guide pipes 64; a driving motor 65 is fixedly connected to the top of the inner cavity of the detection box 1, and a driving gear 651 is fixedly connected to the end of the output shaft of the driving motor 65, and a driven gear 652 is fixedly connected to the outer wall of the driving shaft 3, and the driven gear 652 is meshingly connected with the driving gear 651.

[0044] Through the above-mentioned structure, the waterproof coating is poured from the feed pipe 611 into the coating bin 61, and the drive motor 65 is turned on at the same time. Through the meshing relationship between the driven gear 652 and the drive gear 651, the drive shaft 3 is driven to rotate, and the waterproof coating entering the coating bin 61 will enter the feed ring 63 along the guide pipe 64 and the feed pipe 632, and then enter the spray box 31 along the feed slot 631. At this time, the drive shaft 3 drives the spray box 31 to rotate. Under the action of centrifugal force and gravity, the waterproof coating will be sprayed from the spray head 311 into the detection disk 21 to form a uniform waterproof coating. When the waterproof coating is condensed, clean water is poured into the water spray bin 62 from the water supply pipe 621. At this time, the drive shaft 3 continues to rotate, and the clean water will be sprayed onto the waterproof coating along the spray head 311, achieving a uniform spraying effect and effectively improving the detection effect.

[0045] Reference Figure 2 , Figure 3 and Figure 5 , wherein, an air guide plate 7 is fixedly connected to the top of the feed tray 6, the top of the driving shaft 3 passes through the air guide plate 7 and is fixedly connected to an air guide blade 71, and an air inlet ring 72 is rotatably connected to the outer wall of the driving shaft 3 in the air guide plate 7, the air inlet ring 72 is fixedly connected to the top of the feed tray 6, and an air inlet pipe 721 is fixed and connected to the side wall of the air inlet ring 72, the air inlet pipe 721, the air inlet ring 72 and the feed trough 631 are connected, the top of the air guide plate 7 is fixed and connected to an exhaust pipe 73, and three groups of exhaust pipes 73 are arranged at equal intervals along the center of the air guide plate 7, the bottom ends of the three groups of exhaust pipes 73 all pass through and extend to the top of the detection plate 21, and the bottom ends of the exhaust pipes 73 are higher than the spray box 31.

[0046] Through the arrangement of the above structure, the driving shaft 3 will drive the air guide blades 71 to rotate, thereby pushing the airflow in the air guide plate 7 into the feed trough 631 through the air inlet pipe 721. During the process of spraying the waterproof layer, the spraying of the waterproof coating will be accelerated, thereby improving the spraying efficiency. After the waterproof layer is sprayed, the airflow will be output downward from the spray head 311, and the exhaust pipe 73 will draw the airflow on the top of the detection plate 21 back into the air guide plate 7, thereby forming an accelerated gas flow effect on the surface of the detection plate 21, effectively accelerating the condensation speed of the waterproof coating and improving the detection efficiency.

[0047] Reference Figure 6-Figure 9, wherein the smearing part includes a smearing plate 8, and storage grooves 81 are provided on both sides of the inner cavity of the spray box 31. The smearing plate 8 is slidably connected in the storage groove 81. An inflation ring 82 is fixedly connected to the top of the spray box 31, and the inflation ring 82 is communicated with the inner cavity of the storage groove 81. An elastic rope 83 is fixedly connected between the top of the smearing plate 8 and the top of the inner cavity of the inflation ring 82. An inflation part for pushing the smearing plate 8 to move is provided in the guide tube 64; the inflation part includes a sliding plate 84, and the sliding plate 84 is slidably connected in the guide tube 64. A third spring 841 is fixedly connected between the bottom of the sliding plate 84 and the guide tube 64. A sealing slip ring 85 is fixedly connected to the bottom end of the guide tube 64. The guide tube 64 and the sealing slip ring 85 are connected through the inflation groove 843. The sealing The slip ring 85 is slidably sleeved on the inflatable ring 82, and the sealing slip ring 85 is connected to the inner cavity of the inflatable ring 82; the cross-section of the sliding plate 84 is set in a "7" shape, and the vertical section of the sliding plate 84 slides in contact with the input port of the feed pipe 632. The vertical section of the sliding plate 84 is used to block the input port of the feed pipe 632 after it is reset. A limiting plate 842 is fixedly connected to the inner wall of the guide tube 64, and the distance from the top of the limiting plate 842 to the input port of the feed pipe 632 is equal to the thickness of the inclined straight section of the sliding plate 84. The limiting plate 842 is used to limit the downward position of the sliding plate 84, so that the sliding plate 84 can only move down to a state flush with the input port of the feed pipe 632, and cooperate with the setting of its inclined straight section to effectively ensure the blanking effect.

[0048] It should be noted that when the elastic rope 83 is naturally stretched, the bottom end of the smear plate 8 is higher than the output port of the spray head 311; when the elastic rope 83 is stretched, the bottom end of the smear plate 8 is lower than the output port of the spray head 311; and the gas pressure generated by the compression of the sliding plate 84 is greater than the pulling force required to stretch the elastic rope 83.

[0049] Through the above-mentioned structure, when the waterproof coating enters the guide tube 64, under the action of its gravity, the sliding plate 84 will be squeezed, so that the sliding plate 84 moves downward, thereby compressing the airflow in the bottom cavity of the guide tube 64, so that this part of the airflow enters the sealing slip ring 85 along the inflation groove 843, and then enters the storage groove 81 along the sealing slip ring 85 and the inflation ring 82, thereby pushing the smear plate 8 to move downward. When the thickness of the waterproof coating reaches the bottom of the smear plate 8, the smear plate 8 will scrape the waterproof coating to form a uniform and dense waterproof coating on its surface, effectively improving the detection effect. When the water flow enters the guide tube 64, under the action of the gravity of the water flow, it will squeeze the sliding plate 84 in the guide tube 64 on the other side to move downward, so that the smear plate 8 extends downward again, thereby realizing the wear resistance detection of the waterproof coating while performing the water spray detection, effectively improving the detection effect.

[0050] Reference Figure 1-Figure 9In the present invention, when in use, the mounting plate 2 is first pressed downward to make the piston rod 221 retract into the piston groove 22, and then the detection disk 21 is inserted between the clamping sliders 41 on both sides along the surface of the mounting plate 2. During this process, the side wall of the detection disk 21 will squeeze the clamping slider 41, so that the clamping slider 41 retracts into the clamping sleeve 4. Finally, when the detection disk 21 is fully inserted, the rebound effect of the first spring 42 will make the detection disk 21 clamped and fixed between the clamping sliders 41 on both sides, effectively improving the stability of the detection, and then the pressure on the mounting plate 2 is released, and the second spring 222 Under the rebound effect, the mounting plate 2 will move up and reset, and the detection disk 21 and the clamping slider 41 will also slide in contact, and finally the detection disk 21 will move to the bottom of the spray box 31; and in the process of resetting the mounting plate 2, the upward movement of the piston rod 221 will generate suction at the bottom of the inner cavity of the piston groove 22, so that the airflow in the collecting groove 51 enters the piston groove 22 along the air guide groove 223, which will make the collecting groove 51 in a negative pressure state, so that the airflow on the surface of the detection disk 21 passes through the leakage hole 211 and enters the collecting groove 51, so as to realize the cleaning of the detection disk 21 and ensure the detection accuracy.

[0051] Pour the waterproof coating from the feed pipe 611 into the coating bin 61, and start the drive motor 65 at the same time, and drive the drive shaft 3 to rotate through the meshing relationship between the driven gear 652 and the drive gear 651, and the waterproof coating entering the coating bin 61 will enter the feed ring 63 along the guide pipe 64 and the feed pipe 632, and then enter the spray box 31 along the feed trough 631. At this time, the drive shaft 3 drives the spray box 31 to rotate, and under the action of centrifugal force and gravity, the waterproof coating will be sprayed from the spray head 311 into the detection disk 21, and the drive shaft 3 will also drive the air guide blade 71 to rotate, so as to push the airflow in the air guide disk 7 into the feed trough 631 through the air inlet pipe 721, so as to accelerate the waterproof coating. Spraying improves the spraying efficiency, so that with the continuous rotation of the spray box 31, a uniform waterproof coating will be formed in the detection disk 21; and when the waterproof coating enters the guide tube 64, under the action of its gravity, it will squeeze the sliding plate 84, so that the sliding plate 84 moves downward, thereby compressing the airflow in the bottom cavity of the guide tube 64, so that this part of the airflow enters the sealing slip ring 85 along the inflation groove 843, and then enters the receiving groove 81 along the sealing slip ring 85 and the inflation ring 82, thereby pushing the smear plate 8 to move downward. When the thickness of the waterproof coating reaches the bottom of the smear plate 8, the smear plate 8 will scrape the waterproof coating to form a uniform and dense waterproof coating on its surface, which effectively improves the detection effect.

[0052] When the waterproof coating completely slides out of the guide tube 64, the squeezing effect on the sliding plate 84 will be released. Under the rebound effect of the third spring 841, the sliding plate 84 will be reset, and the input port of the feed tube 632 will be blocked, and the smear plate 8 will be separated from the surface of the waterproof coating to prevent the waterproof coating from being disturbed by the smear plate 8 during the condensation process, thereby ensuring the condensation effect of the waterproof coating. At this time, the drive shaft 3 continues to rotate, the spray head 311 will output airflow downward, and the exhaust pipe 73 will draw the airflow on the top of the detection disk 21 back into the air guide disk 7, thereby forming an accelerated gas flow effect on the surface of the detection disk 21, effectively accelerating the condensation speed of the waterproof coating and improving the detection efficiency. When the waterproof coating is condensed, clean water is poured into the water spraying tank 62 from the water supply pipe 621. At this time, the driving shaft 3 continues to rotate, and the clean water will be sprayed onto the waterproof coating along the spray head 311, so as to perform a permeability test on the waterproof coating. After the water flows into the guide tube 64, the sliding plate 84 in the guide tube 64 on the other side will be squeezed downward by the gravity of the water flow, so that the smear plate 8 is extended downward again, so that the wear resistance of the waterproof coating can be tested while the water spraying test is being performed, thereby effectively improving the test effect. If the waterproof coating leaks, the water will slide along the leakage hole 211, the collecting tank 51 and the dripping tank 511 into the test paper chuck 5, causing the moisture detection test paper in the test paper chuck 5 to change color, thereby completing the permeability test of the waterproof coating.

[0053] Embodiment 2:

[0055] Step 1, install the detection disk 21 into the detection box 1: press the mounting plate 2 downward to make the piston rod 221 retract into the piston groove 22, and then insert the detection disk 21 along the surface of the mounting plate 2 between the clamping sliders 41 on both sides. During this process, the side walls of the detection disk 21 will squeeze the clamping slider 41, so that the clamping slider 41 retracts into the clamping shell 4. Finally, when the detection disk 21 is fully inserted, the rebound effect of the first spring 42 will make the detection disk 21 be clamped and fixed between the clamping sliders 41 on both sides, thereby effectively improving the stability of the detection.

[0056] Step 2, evenly apply the waterproof coating on the test plate 21: Pour the waterproof coating from the feed pipe 611 into the coating bin 61, and turn on the drive motor 65 at the same time, and drive the drive shaft 3 to rotate through the meshing relationship between the driven gear 652 and the drive gear 651. The waterproof coating entering the coating bin 61 will enter the feed ring 63 along the guide pipe 64 and the feed pipe 632, and then enter the spray box 31 along the feed trough 631. At this time, the drive shaft 3 drives the spray box 31 to rotate, and under the action of centrifugal force and gravity, the waterproof coating will be sprayed from the spray head 311 into the test plate 21 to form a waterproof coating.

[0057] Step 3: Blow air to condense the waterproof coating after application: After the waterproof coating is sprayed, the drive shaft 3 continues to rotate with the air guide blades 71, so as to push the airflow in the air guide plate 7 into the feed trough 631 through the air inlet pipe 721, and the spray head 311 will output the airflow downward, and the exhaust pipe 73 will draw the airflow on the top of the detection plate 21 back into the air guide plate 7, thereby forming an accelerated gas flow effect on the surface of the detection plate 21, effectively accelerating the condensation speed of the waterproof coating and improving the detection efficiency.

[0058] Step 4, water the condensed waterproof coating to complete its permeability test: when the waterproof coating is condensed, pour clean water from the water supply pipe 621 into the water spraying bin 62. At this time, the drive shaft 3 continues to rotate, and the clean water will be sprayed onto the waterproof coating along the spray head 311, so as to perform a permeability test on the waterproof coating. After the water flows into the guide tube 64, the sliding plate 84 in the guide tube 64 on the other side will be squeezed downward by the gravity of the water flow, so that the smear plate 8 is extended downward again, so that the wear resistance of the waterproof coating can be tested while the water is sprayed, and the test effect is effectively improved. If the waterproof coating leaks, the water will slide along the leakage hole 211, the collection tank 51 and the drip tank 511 into the test paper chuck 5, causing the moisture detection test paper in the test paper chuck 5 to change color, thereby completing the permeability test of the waterproof coating.
