[0036] It also includes an air source, which is arranged in the installation cavity 3. The installation cavity 3 forms an air outlet 6 on the side corresponding to the shell 1. In this embodiment, the air source is specifically a fan 7 arranged at the air outlet 6. The air source is used to draw air outward to drive the external air flow into the bellows 2 along the test port 4. The external air flow passes through the test port 4, the bellows 2, the installation cavity 3 in turn and blows out through the air outlet 6.

[0037] It also includes a water drop detection plate 8 and a driving device 9 arranged in the installation cavity 3. The driving device 9 is connected to the water drop detection plate 8 and is used to drive the water drop detection plate 8 to move horizontally and correspond / misalign with the test port 4 along the height direction.

[0038] During the test, the water droplet detection plate 8 is moved to the bottom of the test port 4 by the driving device 9, so as to detect the water droplets dripping on the sample, and after the test is completed, the driving device 9 removes the water droplet detection plate 8 to avoid the frequent impact of water vapor driven by the airflow on the water droplet detection plate 8 during the subsequent drying rate test process, so as to ensure the normal use of the water droplet detection plate 8. At the same time, the removed water droplet detection plate 8 can avoid interfering with the airflow, thereby improving the stability of the airflow at the test port and improving the test accuracy.

[0039] Specifically, the driving device 9 includes a moving seat 10 and a motor 11. The water drop detection plate 8 is fixed to the moving seat 10. A guide rail 12 is provided in the installation cavity 3 and is limited and slidable with the moving seat 10. A driving gear 13 is provided at the output end of the motor 11.

[0046] It also includes an air knife 17, which is arranged on one side of the water droplet detection plate 8. When the driving device 9 drives the water droplet detection plate 8 to move and corresponds to the test port, the air knife 17 is located on one side of the water droplet detection plate 8. The air knife 17 is used to blow air toward the surface of the water droplet detection plate 8.

[0047] By setting the air knife 17, the water droplets on the water drop detection plate 8 can be removed after the detection is completed, so that the water drop detection plate multiple detectors can obtain the maximum water absorption saturation of the sample.

A lifting component 20 is provided in the shell 1 and is connected to the temperature sensing unit 18. The lifting component 20 is used to drive the temperature sensing unit 18 to move toward / away from the test port 4.

[0054] It also includes a dripping device 22, which includes a dropper 23 and a liquid supply device 24. The dropper 23 is arranged above the test port 4, and the liquid supply device 24 is arranged in the shell 1 and connected to the dropper 23. The liquid supply device 24 drips liquid to the test port 4 through the dropper 23.

[0055] Specifically, the liquid supply device 24 includes a water tank 25, a swing rod 26 and a control cylinder 27. The water tank 25 is connected to the dropper 23 through a pump body. Specifically, the pump body is a peristaltic pump to ensure the accuracy of liquid supply, and a liquid level sensor can be set in the water tank 25 to detect the amount of aqueous solution in the water tank 25. The dropper 23 is fixedly connected to the swing rod 26, and the swing rod 26 is rotatably connected to the shell 1. The output end of the control cylinder 27 is rotatably connected to the free end of the swing rod 26. The cylinder is extended and retracted to drive the dropper 23 to swing through the swing rod 26 to correspond / misalign with the test port 4.

[0056] During use, the swing rod 26 is controlled to swing by controlling the air cylinder 27 , thereby achieving the positional alignment between the liquid supply device 24 and the test port 4 . Moreover, the swinging staggered manner can avoid mutual interference with the temperature sensing unit 18 .

[0057] Preferably, a limit block 28 is provided on the swing rod 26, and a limit hole 29 and an adjustment hole 30 are respectively provided on the limit block 28.

[0061] Furthermore, a limiting sleeve 34 is provided on the outer shell of the temperature sensing unit 18 , and the limiting sleeve 34 is used to contact the sample to maintain a gap between the temperature sensing unit 18 and the sample.

[0062] Specifically, the side wall of the limiting sleeve 34 is provided with a sliding groove 35 arranged along the axial direction, and the temperature sensing unit 18 is provided with a positioning hole corresponding to the sliding groove 35 and is connected to a positioning rod. One end of the positioning rod passes through the sliding groove 35 and is connected to the positioning hole.

[0064] Furthermore, a telescopic rod 37 is provided at the connecting plate 21 corresponding to the temperature control unit, and a threaded section is formed at the upper end of the temperature control unit.

[0066] Specifically, in this embodiment, the temperature sensing unit 18 is an infrared thermocouple probe.

[0067] Furthermore, the connecting plate 21 is provided with a height adjustment component corresponding to the wind speed sensor 19 , and the height adjustment component is connected to the wind speed sensor 19 to adjust the height of the wind speed sensor 19 .

[0068] The height adjustment component includes a height adjustment rod 39 and a height adjustment block 40. The height adjustment block 40 is fixedly connected to the wind speed sensor 19.

[0069] During use, the bolts 32 are passed through the two pressure holes 43 in sequence. In the initial state, the two splicing blocks 41 are in a relaxed state. At this time, the splicing blocks 41 can move along the height direction of the height adjustment rod 39, thereby adjusting the height of the wind speed sensor 19. After the adjustment is completed, the bolts 32 are tightened to move the two splicing blocks 41 toward each other, so that both splicing blocks 41 apply force to the height adjustment rod 39, thereby achieving fixation of the position with the height adjustment rod 39.

[0070] This embodiment provides a method for using a textile airflow drying rate tester:

[0071] In the initial state, the driving cylinder drives the connecting plate 21 to move upward, and the control cylinder 27 drives the swing rod 26 to swing, so that the temperature sensing unit 18, the wind speed sensor 19 and the dropper 23 all make way with the test port 4, and further the sample cover is set on the test port 4 and fixed by the fixing part 5, and the fan 7 is further turned on, and the driving cylinder is further driven to drive the connecting plate 21 to move downward, and the control cylinder 27 drives the swing rod 26 to return to its position. At this time, the temperature sensing unit 18 records the sample temperature, and at the same time detects the wind speed above the sample through the wind speed sensor 19 to adjust the wind speed to the required wind speed for detection. At the same time, the motor 11 drives the moving seat 10 to move the water drop detection plate 8 to the test port 4 position.

[0072] Water is further supplied to the dropper 23 through the water tank 25, and the dropper 23 supplies water to the sample through the needle 33, so that the sample absorbs a certain amount of aqueous solution, and the water drop detection plate 8 detects whether the sample has penetrated when absorbing the volume of aqueous solution. If no penetration occurs, the sample is detected by the temperature sensing unit 18 to wait for the sample to stabilize and return to the initial temperature, and the water supply is further increased based on the last water addition, and the test is repeated until the water drop detection plate 8 can detect the penetrated water droplets.

[0073] After the water droplet detection plate 8 detects the water droplets, the air knife 17 blows away the water droplets above the water droplet detection plate 8, and in the next test, the aqueous solution is reduced by a small amount, preferably by 10%, and the above experiment is repeated until the maximum amount of water required for the sample to absorb the aqueous solution to be saturated and no penetration occurs is calculated, thereby obtaining the maximum water absorption capacity of the sample.

[0074] The water drop detection plate 8 is further removed, and a drying rate test is performed based on the maximum water absorption at an appropriate ratio.

[0075] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
