[0002] In the footwear manufacturing industry, waterproof performance directly affects product lifespan and user experience. Waterproof performance refers to the ability of shoe upper fabrics to resist wetting and penetration by water. Most existing shoe upper waterproof tests use the spray method, which involves spraying the shoes under certain conditions and determining the water repellency level based on the degree of water penetration, thereby evaluating the waterproof performance of the fabric. The spray method water repellency test determines the waterproof performance of the fabric. After the sample is sprayed under certain conditions, the water repellency level or score of the fabric is determined by comparing the appearance of the sample with the description and pictures of the water repellency phenomenon.

[0003] A testing device for waterproofing cloth shoe uppers, with publication number "CN115015074A", belongs to the field of waterproofing technology for shoe upper fabrics. The device housing is fixedly connected to the surface of the base, and a transparent plate is fixedly connected to one side of the housing. An inlet / outlet is opened on the lower surface of the transparent plate, and a water collection tank is fitted inside the inlet / outlet. Rollers are fixedly installed at the bottom of the water collection tank. This testing device for waterproofing cloth shoe uppers features a water collection tank with directional horizontal movement, making it easy for users to pull it out of the housing, greatly increasing the space for installing and removing the shoe upper fabric. Furthermore, the compression plate and fabric support seat allow for quick manual installation and tightening of the shoe upper fabric, improving installation convenience and stability. The fabric support seat, driven by a motor, can also adjust its tilt angle during the waterproofing performance test without stopping the test, significantly shortening the test cycle.

[0046] Example 3 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 8 It also includes a suction assembly, which includes two suction frames 18, with a suction box 19 connected between the two suction frames 18. The suction box 19 is connected to a suction port 20 on the side near the cleaning component. An airbag 21 is connected to the suction port 20 inside the suction box 19. The airbags 21 are connected to each other through a suction pipe 24. One end of the suction pipe 24 is connected to a fan 25.

[0047] A piston plate 22 is elastically connected inside the suction box 19. A water storage chamber 23 is provided inside the suction box 19 on the side of the piston plate 22 away from the airbag 21. A spray pipe 26 is connected to one side of the suction assembly through a guide pipe 30. The guide pipe 30 connects the water storage chamber 23 and the spray pipe 26. Two sets of support plates 29 are symmetrically arranged on the conveyor table 1. Support shafts 27 are connected to both ends of the spray pipe 26. One end of the support shaft 27 is rotatably installed in the support plate 29. A high-pressure nozzle 28 is connected to the bottom of the spray pipe 26.

[0048] In this embodiment, a suction box 19 is provided on one side of the cleaning component. The fan 25 is started to absorb the dust and impurities generated during cleaning through the suction port 20. Specifically, the fan 25 is started to use the suction pipe 24 and the air bag 21 to suck up the dust and other impurities generated during cleaning of the shoe surface.

[0049] Multiple airbags 21 are installed inside the suction box 19. During the suction process, the airbags 21 expand, which pushes the piston plate 22 inside the suction box 19. The piston plate 22 squeezes the water in the water storage chamber 23, and forces the water through the guide pipe 30 into the spray pipe 26. Finally, the water is sprayed onto the shoe surface through the high-pressure nozzle 28, achieving the effect of driving the spray during the dust collection process and saving the pump body required for spraying.

[0050] A limiting sleeve 39 is provided at the bottom of the airbag 21. The limiting sleeve 39 is connected to a cover plate 40 via a third spring 42. A movable shaft 41 is connected to one side of the cover plate 40, and a push rod 43 is connected to one side of the piston plate 22. The push rod 43 and the movable shaft 41 are set accordingly.

[0051] In this embodiment, a cover plate 40 is provided at the bottom of the airbag 21 to seal the airbag 21. The cover plate 40 is connected to the limiting sleeve 39 by a third spring 42. An exhaust port is provided on one side of the limiting sleeve 39 to elastically seal the exhaust port of the airbag 21. When the airbag 21 expands, it moves to the side of the piston plate 22. As the airbag 21 continues to expand, the piston plate 22 is pushed. During the process of pushing the piston plate 22, the push rod 43 on one side of the piston plate 22 pushes the movable shaft 41, thereby pushing the cover plate 40 away from the opening of the limiting sleeve 39, thereby opening the exhaust port of the entire airbag 21.

[0052] At this time, the air intake continues, the airbag 21 is depressurized and reset, and the piston plate 22 is elastically connected to the air intake box 19. Therefore, as the airbag 21 resets, the piston plate 22 resets, the water storage chamber 23 is released, and spray water is refilled into the water storage chamber 23. The above actions are repeated to control the spray.

A second eccentric wheel 32 is installed on the surface of the extension rod 31. One end of each set of support shafts 27 passes through the support plate 29 and extends to be flush with one end of the extension rod 31. A gear 35 is connected to the end of the support shaft 27. A rack 34 meshes with one side of the gear 35. The rack 34 is slidably connected to the second guide rail 33. The bottom of the second guide rail 33 is connected to the top plate 36 through a second spring 37. The bottom of the rack 34 is connected to the top plate 36 through a connecting rod 38. The top plate 36 is connected and is set against the outer wall of the second eccentric wheel 32. During the continuous conveying and rotation of the conveying roller 2, the second eccentric wheel 32 is driven to rotate. Utilizing the eccentric structure of the second eccentric wheel 32, the top plate 36, connecting rod 38 and rack 34 are driven to rise and fall in sequence. During the rising and falling of the rack 34, the gear 35 is driven to rotate back and forth, thereby driving the support shaft 27, spray pipe 26 and high-pressure nozzle 28 to swing within a certain angle range, so as to spray the widest possible area for different shoe types and shoe sizes.
