Description

Technical Field

[0002] Suede is the softest and most delicate type of natural animal leather, with the advantages of smooth hand feel, light texture and good breathability. Suede is scarce and expensive, and a large amount of chemical agents are used in the processing of natural leather. It is easily affected by the use environment and may become hard and fade. Imitation suede is a type of high-performance fabric that simulates the texture, appearance and function of natural suede through synthetic fiber materials. It not only retains the softness and beauty of natural suede, but also overcomes the defects of natural suede that is easy to absorb water and deform. Imitation suede is widely used in clothing, automotive interiors and other fields. Imitation suede needs to be waterproofed during the production process. After production is completed, it needs to be tested for waterproof performance. Traditional waterproof performance testing usually requires manual water spraying test. This water spraying test is difficult to detect the waterproof performance under different conditions. At the same time, after the test is completed, water will remain on the surface of the imitation suede, and the imitation suede needs to be manually dried after testing, and the detection efficiency is low.

When the humidity sensor 49 detects a change in humidity, the fan 48 is controlled to turn on, and the fan 48 draws air from the air inlet into the rotating groove. The hot air pushes open the first one-way valve, dries the inside of the detection groove 45, and brings the moisture in the detection groove 45 to the air outlet, pushes open the second one-way valve, and brings the moisture in the detection groove 45 out.

[0027] Working principle of the present invention: When in use, artificial suede is manually placed in the discharge chute 44, and the sealing door 6 is closed. When simulating a windless situation, the first motor 31 is controlled to rotate forward, and the first motor 31 drives the first pinion and the inner shaft 357 to rotate, the first pinion drives the first belt 332 to rotate, and the first belt 332 drives the second pinion 331 to rotate. At this time, the pawl slides on the ratchet, and the inner shaft 357 drives the third pinion to rotate, the third pinion drives the second belt to rotate, the second belt drives the fourth pinion to rotate, the fourth pinion drives the fourth rotating shaft 358 to rotate, the fourth rotating shaft 358 drives the third bevel gear 359 to rotate, and the third bevel gear 35 9 drives the fourth bevel gear 362 to rotate, the fourth bevel gear 362 drives the fifth rotating shaft to rotate, the fifth rotating shaft drives the worm 363 and the fifth bevel gear 365 to rotate, the worm 363 drives the worm wheel 341 to rotate, the fifth bevel gear 365 drives the sixth bevel gear 366 to rotate, the sixth bevel gear 366 drives the sixth rotating shaft to rotate, the sixth rotating shaft drives the spray head 368 to rotate on the disc, the spray head 368 drives the nozzle 369 to rotate, the first water pump pumps the water in the water tank 5 into the spray head 368, the nozzle 369 rotates and sprays the water in the spray head 368 onto the imitation suede, and the second water pump pumps the water inside the testing platform 1 back into the water tank 5.

[0028] When simulating wind conditions, the first motor 31 is controlled to reverse, the first motor 31 drives the first pinion to reverse, the first pinion drives the first belt 332 to rotate, the first belt 332 drives the second pinion 331 to rotate, at this time the pawl is against the ratchet, the ratchet drives the rotating plate 333 to rotate, the rotating plate 333 drives the first rotating shaft to rotate, the first rotating shaft drives the first bevel gear 334 to rotate, the first bevel gear 334 drives the second bevel gear 335 to rotate, the second bevel gear 335 drives the second rotating shaft to rotate, and the second rotating shaft The cam 336 is driven to rotate, and the cam 336 rotates to the base circle and contacts the protruding rod 337. The first spring is stretched to drive the fixed plate to move downward, and the fixed plate drives the sliding rod 338 to slide downward in the support frame. The sliding rod 338 drives the wedge head 339 to move downward, and the wedge head 339 drives the two wedge blocks 346 to move back to back. The wedge block 346 is stuck in the blocking block 342, and the worm gear 341 drives the rotating rod 343 to rotate. The rotating rod 343 drives the first gear 344 to rotate, and the first gear 344 drives the second gear 355 to rotate.

[0029] When the second gear 355 rotates, the second gear 355 drives the third rotating shaft to rotate, the third rotating shaft drives the third connecting rod 354 to rotate, the third connecting rod 354 drives the second connecting rod 353 and the outer shaft 356 to rotate, the outer shaft 356 drives the extension plate to rotate, the extension plate drives the fourth rotating shaft 358 to rotate around the outer shaft 356, and the third support plate drives the fifth rotating shaft to rotate around the outer shaft 356, so that the nozzle 369 swings back and forth, and the sprayed water flow will produce an inclination, which effectively detects the waterproof performance of the imitation suede in complex environments such as multi-angle oblique rain caused by wind and wind-blown raindrop impact during actual use, so that the test results have high adaptability and accuracy.

[0030] When the nozzle 369 is spraying water, the humidity sensor 49 senses whether the humidity in the detection tank 45 changes. If the humidity does not change, it means that the waterproof performance of the imitation suede is qualified. If the humidity changes, it means that water has leaked from the imitation suede into the detection tank 45 and the waterproof performance is unqualified. After the test is completed, the second motor 41 is controlled to start, and the second motor 41 drives the magnet 46 to rotate. The magnet 46 cuts the copper tube 47 to generate eddy current, heats the copper tube 47, and the magnet 46 drives the dehydration tray 43 to rotate. The dehydration tray 43 drives the imitation suede to rotate, and the water stains on the surface of the imitation suede are dried. When water leakage occurs, the fan 48 is controlled to start, and the fan 48 draws air from the air inlet into the rotating tank. The hot air pushes open the first one-way valve, dries the inside of the detection tank 45, and brings the moisture in the detection tank 45 to the air outlet, pushes open the second one-way valve, and brings the moisture in the detection tank 45 out. The second one-way valve prevents external moisture from entering the detection tank 45 to avoid affecting the test results.
