Description

Technical Field

[0001] The present invention relates to the technical field of cloth detection, and in particular to a cloth detection workbench. Background Art

[0002] With the continuous development of social economy and the continuous improvement of people's living standards, people have begun to pay attention to the quality of the clothes they wear. The waterproofness and breathability of fabrics directly affect the functionality, comfort and applicable scenarios of clothing. The two together determine whether the clothing can maintain physical comfort while protecting the wearer. If the fabric is not waterproof, moisture can easily penetrate, causing the inner layer of the clothing (such as down, cotton) to clump or lose its warmth. If the fabric is not breathable, it can easily lead to sweat retention, causing skin discomfort or the risk of hypothermia (such as wet underwear in cold environments). Therefore, when the fabric is produced, it is necessary to test the waterproofness and breathability of the fabric.

[0003] Chinese patent CN118777171B published on January 7, 2025 discloses a knitted fabric quality inspection device, which uses a partition to squeeze the gas on the lower side of the fabric through a connecting pipe to the lower side of the partition for collection, preventing residual gas on the lower side of the fabric, avoiding errors in the results of subsequent tests, and ensuring the authenticity of the detected fabric waterproof performance. However, this knitted fabric quality inspection device can only perform waterproof testing on a single fabric. After the test is completed, the staff needs to remove the fabric again and move to the next testing process for air permeability testing, thereby reducing the efficiency of fabric testing.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] Example 1: Please refer to Figures 1-13 The present invention provides a technical solution: a fabric testing workbench, comprising a workbench 1, a hydraulic cylinder 2 is fixedly connected to the outer wall of the workbench 1, a mounting bracket 3 is fixedly connected to the outer wall of the hydraulic cylinder 2, a pressing cover 4 is fixedly connected to the outer wall of the bottom end of the mounting bracket 3, a testing component for testing the fabric is provided on the inner wall of the workbench 1, the testing component includes a water collecting trough 12 provided on the inner wall of the workbench 1, a receiving groove 13 adapted for the water collecting trough 12 is provided on the outer wall of the top end of the workbench 1, a connecting column 15 is slidably connected to the inner wall of the workbench 1, and a The connecting column 15 is adapted to a connecting spring 16, and a placement plate 17 is fixedly connected to the top outer wall of the connecting column 15. The placement plate 17 is sealed and slidably connected to the receiving groove 13 through a guide opening and closing mechanism. A liquid inlet pipe 23 adapted to the water collecting tank 12 is provided on the bottom outer wall of the placement plate 17, and a groove 22 adapted to the liquid inlet pipe 23 is provided on the inner wall of the placement plate 17. A connecting plate 24 is slidably connected to the inner wall of the groove 22, and a through hole 25 is provided on the outer wall of the connecting plate 24. A driving mechanism for pushing the liquid inside the water collecting tank 12 and the connecting plate 24 to rise and fall is provided on the outer wall of the placement plate 17.

[0020] When in use, first spread the cloth on the surface of the placing plate 17, then start the hydraulic cylinder 2 to push the pressing cover 4 to move in the direction of the placing plate 17 through the mounting bracket 3, so that the pressing cover 4 presses the surface of the cloth and the placing plate 17, and the pressure of the pressing cover 4 on the surface of the cloth and the placing plate 17 is used to limit the cloth. Then the hydraulic cylinder 2 continues to push the pressing cover 4 to descend, so that the pressing cover 4 pushes the placing plate 17 to move toward the inside of the receiving groove 13. At this time, the driving mechanism will push the connecting plate 24 to slide toward the inside of the groove 22, and the placing plate 17 will push the connecting column 15 to slide toward the inside of the workbench 1 and squeeze the connecting spring 16 when it moves downward. When the placing plate 17 enters the inside of the receiving groove 13, it will drive the opening and closing mechanism to work, realizing the sealed connection between the placing plate 17 and the receiving groove 13. At this time, the placing plate 17 continues to descend, so that the placing plate 17 squeezes the air inside the receiving groove 13, and the air inside the receiving groove 13 is squeezed After being pressed, it will enter the interior of the groove 22 through the liquid inlet pipe 23, and then pass through the through hole 25 to the top of the connecting plate 24, and cooperate with the placement plate 17 to continuously squeeze the air inside the storage groove 13, so that the air entering the interior of the groove 22 is under the action of pressure and passes through the fabric into the interior of the pressing cover 4, thereby completing the test of the air permeability of the fabric. After that, as the placement plate 17 continues to descend, the driving mechanism works to push the liquid inside the water collection tank 12 to rise. When the liquid inlet pipe 23 enters below the water surface, by squeezing the liquid inside the water collection tank 12, the water enters the interior of the groove 22 through the liquid inlet pipe 23 and the through hole 25, and through the slow rise of the water level inside the groove 22, the water surface contacts the fabric. As time goes by, the water pressure inside the groove 22 will slowly increase, and the pressure acting on the surface of the fabric will also increase accordingly. By observing the permeability of water to the fabric under different pressures, the waterproofness test of the fabric can be completed.

[0021] See also Figure 3 and Figure 13 An auxiliary ring 51 adapted to the connecting plate 24 is provided on the top outer wall of the placement plate 17. The auxiliary ring 51 includes an auxiliary ring body 5101 and an inclined surface 5102. A rubber ring 5 is provided on the bottom outer wall of the pressing cover 4.

[0022] During use, when the cloth is spread flat on the surface of the placement plate 17, it will cover the surface of the connecting plate 24 and the auxiliary ring body 5101. When the pressing cover 4 is pressed down, the rubber ring 5 will first contact the cloth on the surface of the inclined surface 5102. At this time, the pressing cover 4 continues to move downward, causing the rubber ring 5 to squeeze the cloth and the surface of the inclined surface 5102, and through the friction force of the rubber ring 5 and the inclined surface 5102, when the pressing cover 4 continues to move downward, the rubber ring 5 will push the cloth to slide outward along the surface of the inclined surface 5102, thereby stretching the cloth above the connecting plate 24, and preventing the cloth on the surface of the groove 22 from sinking downward due to the influence of gravity when the connecting plate 24 descends, thereby causing air and water to be unable to contact the cloth evenly, thereby affecting the accuracy of cloth detection.

[0023] In order to prevent the cloth from entering the interior of the storage groove 13 when the cloth size is larger than the size of the placement tray 17, thereby affecting the sealing between the placement tray 17 and the storage groove 13, please refer to Figure 2 、 Figure 4 and Figure 5 The opening and closing mechanism includes a plurality of telescopic blocks 18 arranged at equal intervals along the circumferential direction of the outer periphery of the placement tray 17, and the plurality of telescopic blocks 18 cooperate to form a sealing ring, and a guide ring 14 installed on the outer wall of the workbench 1, and a telescopic spring 19 adapted to the telescopic block 18 is provided on the inner wall of the placement tray 17. The guide ring 14 includes a guide ring body 1401, and an outer inclined surface 1402 is provided on the outer wall of the guide ring body 1401 away from the receiving groove 13, and an inner inclined surface 1403 is provided on the outer wall of the guide ring body 1401 close to the receiving groove 13.

[0024] When in use, the telescopic block 18 is perpendicular to the surface of the workbench 1 in the initial state. When the placement tray 17 descends, the cloth will also descend synchronously. When the bottom end of the cloth contacts the outer inclined surface 1402, the outer inclined surface 1402 can guide the forward direction of the bottom end of the cloth, so that the bottom end of the cloth moves toward the surface of the workbench 1, thereby preventing the excess cloth from the surface of the placement tray 17 from entering the interior of the storage groove 13. When the telescopic block 18 contacts the inner inclined surface 1403, the inner inclined surface 1403 will squeeze the telescopic block 18, so that multiple groups of telescopic blocks 18 slide toward the interior of the placement tray 17 and squeeze the telescopic spring 19. When the placement tray 17 enters the interior of the storage groove 13, the multiple groups of telescopic blocks 18 will close with each other and form a sealing ring between the placement tray 17 and the storage groove 13, thereby ensuring the sealing between the placement tray 17 and the storage groove 13.

[0025] See also Figure 6 and Figure 7The driving mechanism includes a connecting shaft 20 mounted on the outer wall of the bottom end of the placement plate 17, and a piston rod 26 arranged on the outer wall of the bottom end of the connecting plate 24. A connecting sleeve 21 adapted to the connecting shaft 20 is provided on the inner wall of the water collecting tank 12, a piston cavity 27 adapted to the piston rod 26 is provided on the inner wall of the connecting shaft 20, an air intake channel 28 adapted to the piston cavity 27 is provided on the inner wall of the connecting shaft 20, a piston 29 is slidably connected to the inner wall of the connecting sleeve 21, and the piston 29 separates the connecting sleeve 21 into an air tank 30 and an oil tank 31.

[0026] During use, in the initial state, the space above the piston rod 26 inside the piston chamber 27 is in a low-pressure state. When the placement plate 17 descends, it pushes the connecting shaft 20 to slide toward the inside of the air chamber 30, so that the connecting shaft 20 squeezes the air inside the air chamber 30. After being squeezed, the air inside the air chamber 30 will enter the inside of the air inlet channel 28, and finally be discharged into the piston chamber 27, so that the air pressure inside the piston chamber 27 returns to normal. At this time, the connecting plate 24 and the piston rod 26 move downward under the action of force, so that the connecting plate 24 slides into the inside of the groove 22, thereby ensuring that the air and water can contact the fabric in a balanced manner when entering the inside of the groove 22.

[0027] See also Figure 2 、 Figure 10 、 Figure 11 and Figure 12 The driving mechanism also includes a limiting slider 32 installed on the outer wall of the piston 29, a connecting hole 33 is opened on the outer wall of the top end of the piston 29, a force plate 39 is slidably connected to the inner wall of the connecting hole 33, and a transmission block 40 is rotatably connected to the inner wall of the bottom end of the force plate 39. A transmission rod 41 adapted to the transmission block 40 is provided on the inner wall of the bottom end of the piston 29, and a return spring 42 adapted to the transmission rod 41 is provided on the inner wall of the bottom end of the piston 29. A latch 43 is fixedly connected to the outer wall of one end of the transmission rod 41, and the latch 43 is fixedly connected to the outer wall of the transmission rod 41. 3 passes through the inner wall of the limit slider 32 horizontally, a slide groove 44 adapted to the limit slider 32 is provided on the inner wall of the connecting sleeve 21, a clamping groove 45 adapted to the latch 43 is provided on the inner wall of the slide groove 44, a pressing column 49 adapted to the connecting hole 33 is provided on the outer wall of the bottom end of the connecting shaft 20, an oil inlet channel 46 adapted to the oil tank 31 is provided on the inner wall of the bottom end of the workbench 1, a push rod 47 is slidably connected to the inner wall of one end of the oil inlet channel 46, and a piston plate 48 adapted to the water collecting tank 12 is provided on the outer wall of the top end of the push rod 47.

[0028] When in use, when the connecting shaft 20 moves downward, it will push the pressing column 49 to move downward synchronously, so that the pressing column 49 enters the interior of the connecting hole 33 and presses the force-bearing plate 39. After the force-bearing plate 39 is pressed, it will push the transmission block 40 to squeeze the interior of the piston 29. The reaction force of the piston 29 on the transmission block 40 causes the transmission block 40 to rotate on the surface of the force-bearing plate 39. When the transmission block 40 rotates, it can provide a pulling force to the transmission rod 41, thereby pulling the transmission rod 41 to slide toward the force-bearing plate 39 and squeezing the return spring 42. When the transmission rod 41 slides toward the force-bearing plate 39, it will pull the pin 43 to slide out of the interior of the card slot 45, thereby contacting the limit of the piston 29. At this time, the piston can be pushed by the downward movement of the connecting shaft 20 29 slides downward inside the slide groove 44 through the limiting slider 32, so that the piston 29 squeezes the hydraulic oil inside the oil tank 31 and squeezes the hydraulic oil into the oil inlet channel 46, thereby increasing the pressure inside the oil inlet channel 46, thereby pushing the push rod 47 to rise. When the push rod 47 rises, it will push the piston plate 48 to move upward synchronously. When the piston plate 48 moves upward, it can push the liquid inside the water collecting tank 12 to rise, thereby raising and squeezing the water level inside the water collecting tank 12, so that water can enter the inside of the groove 22 through the liquid inlet pipe 23. When the pressing column 49 slides out of the connecting hole 33, the force of the reset spring 42 pushes the transmission rod 41 to reset, thereby inserting the pin 43 into the slot 45 again and limiting the piston 29 again.

[0029] See also Figure 8 、 Figure 9 and Figure 12 The driving mechanism also includes a limit block 34 arranged on the inner wall of the piston 29, a spring piece 35 adapted to the limit block 34 is provided on the inner wall of the piston 29, a slider 36 is slidably connected to the outer wall of the piston 29, a pressing block 37 is fixedly connected to the outer wall of one end of the slider 36, a guide groove 38 adapted to the pressing block 37 is provided on the outer wall of one end of the limit block 34, and a notch 50 adapted to the limit block 34 is provided on the outer wall of the pressing column 49.

[0030] When in use, when the connecting shaft 20 pushes the piston 29 to move downward, the top surface of the slider 36 separates from the top inner wall of the slide groove 44, thereby contacting the slider 36. At this time, the spring sheet 35 is forced to push the limit block 34 to slide toward the connecting hole 33, so that one end of the limit block 34 is inserted into the inside of the notch 50. At the same time, the guide groove 38 pushes the upward pressing block 37 to slide out. When the pressing block 37 slides out of the inside of the guide groove 38, it drives the slider 36 to slide upward. When the connecting shaft 20 slides upward, the connection between the limit block 34 and the notch 50 makes the connecting shaft 20 can drive the piston 29 to move upward synchronously through the pressing column 49, and draw the hydraulic oil inside the oil inlet channel 46 back to the inside of the oil tank 31. When the slider 36 moves upward to the top of the slide groove 44 through the piston 29, the force acting on the surface of the slider 36 through the inner wall of the slide groove 44 will push the slider 36 to move downward, so that the slider drives the pressing block 37 to squeeze the guide groove 38, thereby pulling the limit block 34 out of the notch 50 and applying force to the spring sheet 35, thereby releasing the limit on the pressing column 49, allowing the pressing column 49 to slide out of the inside of the connecting hole 33.

[0031] See also Figure 3 A connecting pipe 6 is fixedly connected to the outer wall of the top of the pressing cover 4, and a connecting rod 9 is slidably connected to the inner wall of the bottom end of the connecting pipe 6. A sealing plate 10 adapted to the connecting pipe 6 is provided on the outer wall of the bottom end of the connecting rod 9, and a floating block 11 is fixedly connected to the outer wall of the sealing plate 10.

[0032] During use, water will enter the interior of the pressing cover 4 after penetrating the surface of the fabric. As time goes by, the water level inside the pressing cover 4 will become higher and higher. When the water level overflows the floating block 11, the floating block 11 will push the blocking plate 10 up under the action of buoyancy, causing the connecting rod 9 to slide into the interior of the connecting pipe 6, so that the blocking plate 10 can block the bottom end of the connecting pipe 6 to prevent water from entering the interior of the connecting pipe 6.

[0033] See also Figure 3 A dynamic pressure sensor 7 is installed on the inner wall of the connecting pipe 6, and a waterproof camera 8 is installed on the inner wall of the pressing cover 4.

[0034] When in use, the dynamic pressure sensor reflects the flow rate by measuring the dynamic pressure generated by the air flow, so that it can accurately detect the air permeability of the fabric, and the camera 8 can monitor the waterproof condition of the fabric surface under pressure conditions in real time, so that it can accurately detect the waterproofness of the fabric.
