A bevel gear is fixed to the bottom end of the transmission rod 21, and a bevel gear is also fixed to the end of the rotating shaft of the conveyor belt 2 near the transmission rod 21. The bevel gear of the transmission rod 21 is meshed with the bevel gear at the end of the rotating shaft of the conveyor belt 2. A support frame 31 is provided above the rotating disk 3, and the bottom end of the support frame 31 is fixedly connected to the top of the housing 1. A water retaining shell 5 is fixed to the top of the interior of the housing 1. A motor 23 is installed on the outside of the housing 1, and the end of the rotating shaft of the motor 23 is fixedly connected to the end of the rotating shaft of the conveyor belt 2. After the diaper pad is produced, it is necessary to test the waterproofness of its surface. When testing, water needs to be sprinkled on the surface of the diaper pad, and the waterproof performance is judged by observing the water penetration on the surface of the diaper pad. During the test, the diaper pad to be tested is placed into the shell 1 through the opening 11. At this time, the diaper pad is placed on the top of the conveyor belt 2, and then the motor 23 is started to drive the conveyor belt 2 to roll. At this time, the conveyor belt 2 can drive the diaper pad to move. When the front end of the diaper pad moves to the position below the water retaining shell 5, the camera 35 takes a picture, and the water nozzles corresponding to the three cameras 35 are judged according to the current picture. Position, then start the motor 23 to rotate and drive the shaft of the conveyor belt 2 to roll, the shaft drives the transmission rod 21 through the bevel gear, the transmission rod 21 drives the first belt pulley 211 to rotate through the belt to drive the second belt pulley 221, at this time, the first transmission gear 22 drives the rotating disk 3 to rotate as the second belt pulley 221 rotates, the rotating disk 3 drives the single-point water spray head 32 to rotate to the inside of the water retaining shell 5, at this time, the single-point water spray head 32 is placed in the center of the water retaining shell 5, and then water is delivered to the water delivery hole 371 through the water inlet head 4, the water inlet head 4 is connected to the external water source, and the water delivery hole 371 injects water into the single-point water spray head 32 The single-point water spray head 32 sprays water to perform a single-point waterproof test. At this time, the two cameras 35 placed inside the water retaining shell 5 take pictures of the current urine-proof pad. Then, the rotating disk 3 rotates 120° to rotate the single-point water spray head 32 to the outside of the water retaining shell 5. At the same time, the multi-point water spray head 33 can be rotated to the inside of the water retaining shell 5. At the same time, the camera 35 placed outside the water retaining shell 5 takes pictures of the position where the urine-proof pad sprays water. The waterproof performance is judged by comparing the pictures when spraying water. At the same time, the multi-point water spray head 33 sprays multi-point water flows, and the judgment is made in the same way as above. Then the connecting pipe 34 enters the water retaining shell. Inside the water shell 5, after the water receiving box 36 below the connecting pipe 34 is filled with water, the water flow can be splashed onto the surface of the urine-isolating pad through the water receiving box 36, so as to test the splash waterproof effect. The water-retaining shell 5 can divide the urine-isolating pad into multiple areas during the test, so that the waterproof performance of the same urine-isolating pad can be tested in various environments. The transmission ratio between the first transmission gear 22 and the rotating disk 3 is relatively large. When the rotating disk 3 rotates one-third of a circle, the rotating shaft of the conveyor belt 2 rolls multiple circles. At this time, the conveyor belt 2 can drive the area after the urine-isolating pad is tested to move to a position away from the water-retaining shell 5, so that the area after the urine-isolating pad is tested does not affect subsequent tests.

[0024] like Figures 1 to 3 As shown, a rotation opening is provided on one side of the top of the water retaining shell 5, and one side of the rotating disk 3 extends into the interior of the water retaining shell 5 through the rotation opening; When the rotating disk 3 rotates, the single-point water spray head 32, the multi-point water spray head 33 and the connecting pipe 34 can be rotated inside the water retaining shell 5 through the rotating opening of the water retaining shell 5, so as to switch the waterproof test in different environments conveniently.

[0025] like Figures 1 to 3 As shown, a water guide baffle 51 is fixed to the bottom end of the water retaining shell 5, and a water guide hole 52 is opened on one side of the water retaining shell 5; When the water receiving box 36 splashes water onto the surface of the urine-isolating pad, part of the water will be splashed onto the inner wall of the water retaining shell 5. In order to prevent the water flow on the inner wall of the water retaining shell 5 from dripping onto the urine-isolating pad, a water guide baffle 51 is provided to guide the water flow. At the same time, the water flow can be discharged to the outside through the water guide hole 52, which can prevent the water flow on the inner wall of the water retaining shell 5 from affecting the detection result.

When the water receiving box 36 is full, the motor 365 is started to drive the second transmission gear 367 to rotate, and the second transmission gear 367 drives the tooth surface 364 to rotate. At this time, the tooth surface 364 drives the connecting arm 362 to swing, and the connecting arm 362 drives the water receiving box 36 to swing. After the tooth surface 364 rotates 90°, the motor 365 drives the second transmission gear 367 to quickly rotate in the opposite direction and reset. At this time, the water in the water receiving box 36 can be splashed out, and the splashing waterproof effect can be tested at this time.

[0027] like Figures 4 to 7 As shown, a limiting column 368 is provided on one side of the connecting arm 362 away from the tooth surface 364, and the limiting column 368 is fixedly connected to the connecting tube 34, and the connecting arm 362 is in a vertical state and is tightly attached to the limiting column 368; When the second transmission gear 367 drives the tooth surface 364 to reset, the limiting column 368 can limit the connecting arm 362 to prevent the connecting arm 362 from excessively rotating when resetting.

[0028] like Figures 5 to 7 As shown, a take-up drum 366 is fixed to one side of the second transmission gear 367 away from the motor 365, and a pull rope 361 is fixed to both sides of the bottom end of the water receiving box 36, and the top end of the pull rope 361 is wound around the outside of the take-up drum 366; When the second transmission gear 367 rotates, the take-up drum 366 is driven to reel in the pull rope 361. At this time, the pull rope 361 can pull one end of the water receiving box 36 upward, so that the water receiving box 36 can rotate while swinging. At this time, the water inside the water receiving box 36 can be better splashed out, which is more convenient for testing.

When the water receiving box 36 spills water, the connecting pipe 34 needs to stop injecting water. At this time, the rotation of the connecting arm 362 will push the pushing frame 342 to move, and the protrusion 344 inside the pushing frame 342 moves and slides inside the steering slide groove 345. At this time, the connecting rod 346 will be driven to rotate 90°, and the connecting rod 346 drives the rotating ball 341 to rotate 90°. At this time, the rotating ball 341 can block the connecting pipe 34, and the connecting pipe 34 will not discharge water. When the connecting arm 362 is reset, the first spring 343 pushes the pushing frame 342 to reset. At this time, the pushing frame 342 drives the rotating ball 341 to rotate in the opposite direction. At this time, the rotating ball 341 can be reset, and the switch of the connecting pipe 34 can be automatically controlled.
