Description

Technical Field

[0001] The present invention relates to the field of fabric testing, and particularly to a fabric waterproofness detection device and a detection method thereof. Background Art

[0002] During the production process of fabrics, it is usually necessary to detect their waterproof performance. The detection of fabric waterproofness is an important test for evaluating the ability of fabrics to resist liquid penetration, and is widely used in fields such as outdoor clothing, medical supplies, and industrial protection.

[0003] Common fabric waterproofness detection methods mostly use the static water column method to simulate the ability of fabrics to resist water penetration under a water pressure environment. By continuously increasing the water pressure, the maximum pressure value when water penetrates the fabric is measured. Usually, testers need to manually fix and position the fabric, then continuously inject water and change the height of the water column until water seeps through the fabric above. The testers continuously observe the penetration phenomenon of the fabric, which increases the workload and intensity of the testers, and also increases the difficulty of experimental observation, making it inconvenient for fabric waterproofness testing.

[0064] The present invention also provides a detection method for a fabric waterproofness detection device, including the following specific usage steps:

[0065] Step 1: First, place the fabric to be detected on the upper surface of the placement table. The fabric is located above the through hole. Turn on the servo motor switch. The servo motor drives the rotating disk to rotate clockwise. The extrusion grooves on the rotating disk rotate together. As the rotating disk rotates, the inner wall of the extrusion groove squeezes the bottom of the first connecting column, pushing the first connecting column to move outward. The first connecting column drives the bottom of the connecting rod to move together. The top of the connecting rod drives the water storage pipe and the fixing ring to move downward together. The bottom of the fixing ring squeezes the fabric on the upper surface of the placement table. The bottom of the fixing ring drives the fabric to penetrate into the inner cavity of the placement groove to tension the fabric. The bottom end of the water storage pipe presses and fixes the fabric. At this time, the first connecting column moves into the inner cavity of the movable groove;

[0066] Step 2: Next, the servo motor drives the rotating disk to continue rotating clockwise. The bottom of the first connecting column squeezes the top of the movable block, causing the movable block to move downward. The connecting block moves together with the movable block. The second connecting column slides from the first installation groove into the inner cavity of the second installation groove to limit the connecting block. As the rotating disk rotates clockwise, it drives the connecting block to rotate to the position of the stopper, causing the connecting block to push the stopper and the movable ring to rotate together. The inner wall of the third installation groove on the movable ring squeezes the third connecting column, pushing the third connecting column and the piston rod to move vertically downward to squeeze the clear water in the inner cavity of the piston cylinder, so that the clear water enters the inner cavity of the water storage pipe along the connecting pipe and the water inlet pipe. The clear water in the water storage pipe falls on the upper surface of the fabric to test the waterproofness of the fabric;

[0067] Step 3: Then, as the rotating disk rotates clockwise, it pushes the piston rod to squeeze the clear water in the inner cavity of the piston cylinder, causing the liquid level of the clear water in the water storage pipe to slowly rise, changing the height of the water column. As the height of the water column increases, the pressure on the fabric increases, causing the clear water to penetrate through the fabric and contact the lower water inlet test paper, causing the color of the water inlet test paper to change. Use the image sensor to obtain the color information of the water inlet test paper. When the color of the water inlet test paper changes, transmit the information of the image sensor to the control screen. At this time, stop the operation of the servo motor. The liquid level height of the clear water in the inner cavity of the water storage pipe reflects the waterproofness of the fabric. Then, the servo motor drives the rotating disk to rotate counterclockwise, driving the piston rod to move upward to extract the clear water in the inner cavity of the water storage pipe. After the clear water extraction is completed, the rotating disk pushes the first connecting column to move inward, the connecting rod pushes the water storage pipe to move upward, and drives the bearing plate to move upward to release the positioning of the fabric, take out the fabric, and replace the water inlet test paper.

[0068] The technical effects and advantages of the present invention:

[0069] (1) The present invention utilizes a setting method in which a rotating disk, a piston cylinder, a piston rod, a water storage pipe, a water inlet test paper, and an image sensor cooperate. By the clockwise rotation of the rotating disk, the piston rod is pushed to squeeze the clear water in the inner cavity of the piston cylinder, causing the liquid level of the clear water in the water storage pipe to slowly rise, changing the height of the water column. As the height of the water column increases, the pressure on the fabric increases, enabling the clear water to penetrate through the fabric and contact the water inlet test paper below, causing the color of the water inlet test paper to change. The image sensor is used to obtain the color information of the water inlet test paper, and the information of the image sensor is transmitted to the control screen. The liquid level height of the clear water in the inner cavity of the water storage pipe reflects the waterproof property of the fabric, facilitating the testing of the waterproof property of the fabric;

[0070] (2) The present invention utilizes a setting method in which a rotating disk, a first connecting column, a movable block, a connecting block, a stop block, a movable ring, a third installation groove, a third connecting column, and a piston rod cooperate. The servo motor drives the rotating disk to rotate clockwise, and the bottom of the first connecting column squeezes the top of the movable block, causing the movable block to move downward. The connecting block moves together with the movable block, driving the connecting block to rotate to the position of the stop block, causing the connecting block to push the stop block and the movable ring to rotate together. The inner wall of the third installation groove on the movable ring squeezes the third connecting column, pushing the third connecting column and the piston rod to move vertically downward, squeezing the clear water in the inner cavity of the piston cylinder, causing the clear water to enter the inner cavity of the water storage pipe along the connecting pipe and the water inlet pipe. The clear water in the water storage pipe falls on the upper surface of the fabric, facilitating the testing of the waterproof property of the fabric and facilitating the suction and discharge of the clear water;

[0071] (3) The present invention utilizes a setting method in which a rotating disk, an extrusion groove, a first connecting column, a connecting rod, a water storage pipe, a fixing ring, and a placement groove cooperate. By placing the fabric to be tested on the upper surface of the placement table, the servo motor drives the rotating disk to rotate clockwise, and the extrusion groove on the rotating disk rotates together. As the rotating disk rotates, the inner wall of the extrusion groove squeezes the bottom of the first connecting column, pushing the first connecting column to move outward, driving the bottom of the connecting rod to move together. The bottom of the connecting rod drives the water storage pipe and the fixing ring to move downward together. The bottom of the fixing ring squeezes the fabric on the upper surface of the placement table, and the bottom of the fixing ring drives the fabric to penetrate into the inner cavity of the placement groove, tensioning the fabric. The bottom end of the water storage pipe presses and fixes the fabric, ensuring the stability and flatness of the fabric. Description of the Drawings

[0093] Usage method of the present invention:

[0094] First, place the cloth to be detected on the upper surface of the placing table 33. The cloth is located above the through hole 34. Turn on the switch of the servo motor 411. The servo motor 411 drives the rotating disk 47 to rotate clockwise. The extrusion groove 48 on the rotating disk 47 rotates together. As the rotating disk 47 rotates, the inner wall of the extrusion groove 48 squeezes the bottom of the first connecting column 49, pushing the first connecting column 49 to move outward. The bottom of the first connecting column 49 drives the bottom of the connecting rod 44 to move together. The top of the connecting rod 44 drives the water storage pipe 35 and the fixing ring 42 to move downward together. The bottom of the fixing ring 42 squeezes the cloth on the upper surface of the placing table 33. The bottom of the fixing ring 42 drives the cloth to penetrate into the inner cavity of the placing groove 43 to tension the cloth. The bottom end of the water storage pipe 35 presses and fixes the cloth. At this time, the first connecting column 49 moves into the inner cavity of the movable groove 64;

[0095] Then, the servo motor 411 drives the rotating disk 47 to continue rotating clockwise. The bottom of the first connecting column 49 squeezes the top of the movable block 65, so that the movable block 65 moves downward. The connecting block 68 moves together with the movable block 65. The second connecting column 612 slides from the first installation groove 610 into the inner cavity of the second installation groove 611 to limit the connecting block 68. As the rotating disk 47 rotates clockwise, it drives the connecting block 68 to rotate to the position of the stop block 617, so that the connecting block 68 pushes the stop block 617 and the movable ring 614 to rotate together. The inner wall of the third installation groove 615 on the movable ring 614 squeezes the third connecting column 616, pushing the third connecting column 616 and the piston rod 62 to move vertically downward to squeeze the clear water in the inner cavity of the piston cylinder 61, so that the clear water enters the inner cavity of the water storage pipe 35 along the connecting pipe 63 and the water inlet pipe 36. The clear water in the water storage pipe 35 falls on the upper surface of the cloth to test the waterproof property of the cloth;

[0096] Then, as the rotating disk 47 rotates clockwise, it pushes the piston rod 62 to squeeze the clear water in the inner cavity of the piston cylinder 61, causing the liquid level of the clear water in the water storage pipe 35 to slowly rise, changing the height of the water column. As the height of the water column increases, the pressure on the fabric increases, causing the clear water to penetrate through the fabric and come into contact with the lower water inlet test paper 38, causing the color of the water inlet test paper 38 to change. The image sensor 39 is used to obtain the color information of the water inlet test paper 38. When the color of the water inlet test paper 38 changes, the information of the image sensor 39 is transmitted to the control screen 2. At this time, the operation of the servo motor 411 is stopped. The liquid level height of the clear water in the inner cavity of the water storage pipe 35 reflects the waterproof property of the fabric. Then, the servo motor 411 drives the rotating disk 47 to rotate counterclockwise, driving the piston rod 62 to move upward to extract the clear water in the inner cavity of the water storage pipe 35. After the clear water extraction is completed, the rotating disk 47 pushes the first connecting column 49 to move inward, and the connecting rod 44 pushes the water storage pipe 35 to move upward, and drives the bearing plate 37 to move upward to release the positioning of the fabric, take out the fabric, and replace the water inlet test paper 38.
