Description

A multi-station garment fabric breathability testing device Technical Field

[0001] This invention relates to the field of garment fabric testing technology, and in particular to a multi-station garment fabric air permeability testing device. Background Technology

[0002] The breathability of clothing fabrics refers to the ability of gas molecules to pass through the fabric. It is one of the important indicators for evaluating the comfort and hygiene of clothing. In the production and quality control process of the textile industry, it is necessary to use specialized breathability testing equipment to conduct strict tests on various fabrics to ensure that the products meet relevant standards and usage requirements.

[0003] Air permeability testing is usually carried out by measuring the airflow rate that passes vertically through a given area of ​​the sample within a certain time under a specified pressure difference, thereby calculating the air permeability rate. In order to meet the needs of large-scale testing in industrial production and improve testing efficiency, existing testing equipment is usually designed with a multi-station structure, that is, to test multiple fabric samples at one time.

[0004] Existing multi-station garment fabric breathability testing equipment typically includes a base, multiple testing ports, and corresponding clamping mechanisms. During use, the operator places the fabric on the testing port and then activates the clamping mechanism to press it down vertically, using a sealing ring to secure the fabric. However, due to the soft and elastic nature of the fabric, it is difficult to ensure absolute flatness during manual placement, resulting in minor wrinkles or inconsistent tightness. To address these issues, current technologies typically rely on operators manually pulling or smoothing the fabric outwards before clamping to eliminate wrinkles. However, manual operation is highly subjective, and the pulling force is difficult to quantify and standardize. Especially during continuous multi-station operation, operator fatigue can easily occur, leading to inconsistent tension on fabrics from different stations and batches. This results in significant differences in the physical tension state of each fabric during testing, severely affecting the consistency of multi-station test data. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-station garment fabric breathability testing device, which solves the problem that when the fabric is fixed in a multi-station testing device, the physical tension state of the fabric at each station is inconsistent during testing, which affects the accuracy and consistency of multi-station breathability test data.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-station garment fabric air permeability testing device, comprising a base, a support plate mounted on the top of the base, a fixing mechanism on the top of the support plate, the fixing mechanism comprising multiple support cylinders, the multiple support cylinders being fixedly connected to the top periphery of the support plate, an adjustment mechanism on the upper side of the support plate, and a collection mechanism on the inner side of the support cylinders; a support plate is fixedly connected to the top of each of the multiple support cylinders, the bottom of each of the multiple support cylinders penetrating the support plate, and a hydraulic rod is fixedly connected to the center of the top of the support plate. A cross bracket is fixedly connected to the output end of the pressure rod. Hollow cylinders are fixedly connected to the bottom four sides of the cross bracket. Multiple U-shaped plates are fixedly connected at equal intervals to the outer side of the hollow cylinders. A fixed rod is fixedly connected to the inner side of the U-shaped plates. A slider is slidably connected to the bottom outer side of the fixed rod. A movable piece is slidably connected to the upper side of the outer wall of the fixed rod. A spring is fixedly connected to the bottom of the movable piece. A connecting plate is rotatably connected to the top of one side of the slider. A push plate is rotatably connected to the bottom of the connecting plate. A spring is fixedly connected to the bottom of one side of the slider. The other end of the spring is fixedly connected to the connecting plate.

[0007] Through the above technical solution, the hydraulic rod drives the cross bracket to move downward, which in turn moves the hollow cylinder and push plate closer to the fabric. The vertical motion is converted into the centrifugal motion of the push plate by the cooperation of the connecting plate and the slider, so as to realize the automatic flattening of the fabric. With the help of springs, excessive stretching is prevented, ensuring that the fabric at multiple stations is in a consistent tension state and improving the accuracy of detection.

[0008] Preferably, the adjusting mechanism includes multiple threaded rods, which are rotatably connected to the top of the left and right sides of the hollow cylinder. A lifting ring is threadedly connected to the outer side of each threaded rod. Multiple insert plates are fixedly connected at equal intervals to the bottom of each lifting ring. The bottom of each insert plate passes through a U-shaped plate and contacts the movable plate. A gear is fixedly connected to the upper side of the outer wall of each threaded rod. A toothed ring is rotatably connected to the top of the hollow cylinder, and the toothed ring meshes with the gear.

[0009] The above technical solution utilizes a knob to rotate a threaded rod, which, in conjunction with the transmission of gears and a gear ring, enables synchronous adjustment on both sides. This drives the lifting ring to move vertically, and by changing the position of the movable piece through a insert plate, the compression of the first spring is adjusted, thereby controlling the flattening force and adapting to the testing requirements of different fabric materials.

[0010] Preferably, the collection mechanism includes a filter screen, which is fixedly connected to the inner side of the support cylinder. A rotating rod is rotatably connected to the bottom of the filter screen, and an impeller is fixedly connected to the bottom of the rotating rod. A curved plate is fixedly connected to the top of the rotating rod through the filter screen. Brush bristles are provided at the bottom of the curved plate. A window is opened in the upper middle part of the inner wall of the support cylinder, and a collection box is fixedly connected to the outer side of the support cylinder. The window communicates with the collection box.

[0011] The above technical solution utilizes the airflow generated by the detection to drive the impeller to rotate, which in turn drives the curved plate and brushes to automatically clean the lint on the surface of the filter screen. The lint enters the collection box through the window, preventing the filter screen from becoming clogged and the air passage from being blocked, thus protecting the flow meter and air pump from damage.

[0012] Preferably, the fixing mechanism further includes a stop block, which is fixedly connected to one side of the slider, and the outer side of the stop block is in contact with the connecting plate.

[0013] The above technical solution limits the extreme rotation position of the connecting plate by the stop block, preventing the connecting plate from jamming due to excessive angle.

[0014] Preferably, the fixing mechanism further includes an anti-slip plate, which is fixedly connected to the bottom of the push plate, and a sealing ring is fixedly connected to the bottom of the hollow cylinder.

[0015] Through the above technical solutions, the anti-slip sheet increases the friction between the push plate and the fabric to ensure a flattening effect, and the sealing ring eliminates the gap between the fabric and the support plate to ensure airtightness.

[0016] Preferably, the fixing mechanism further includes multiple guide rods, which are respectively fixedly connected to the top perimeter of the tray, and the top ends of the guide rods pass through the cross bracket.

[0017] Through the above technical solution, the guide rod restricts the movement trajectory of the cross bracket, prevents swaying or deviation during the lifting process, and ensures accurate alignment of each workstation.

[0018] Preferably, the fixing mechanism further includes an air pump, which is fixedly connected to the bottom of the support plate, and the input end of the air pump is connected to an air pipe.

[0019] Through the above technical solution, the air pump creates negative pressure in the support cylinder through the air pipe, providing a power source for the self-cleaning of the air permeability detection and collection mechanism.

[0020] Preferably, the bottom of the support cylinder is connected to a flow meter, and the bottom of the flow meter is connected to an air pipe.

[0021] Through the above technical solution, the flow meter monitors the gas flow through the fabric in real time, converting the physical airflow into readable data to achieve quantitative detection of air permeability.

[0022] Preferably, the adjustment mechanism further includes a knob, which is fixedly connected to the top of the threaded rod.

[0023] The above technical solution allows operators to easily apply force manually with the knob, simplifying the operation process.

[0024] Preferably, the collection mechanism further includes a lid, which is rotatably connected to one side of the collection box.

[0025] Through the above technical solution, the lid is kept closed to ensure sealing, and when opened, it is convenient to clean the lint accumulated inside the collection box.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects: 1. The present invention uses a hydraulic rod to drive the hollow cylinder downward, so that the anti-slip plate at the bottom of the push plate contacts the fabric before the sealing ring. As the hollow cylinder continues to move downward, the push plate will push the connecting plate to rotate around the slider, thereby driving multiple push plates to make radial centrifugal motion, stretching and stretching the fabric outward, eliminating the difference in tightness of the garment fabric and the interference of wrinkles, ensuring that the fabric at all workstations is in the same physical tension state before being pressed and fixed by the sealing ring, thus improving the accuracy of multi-workstation air permeability test data.

[0027] 2. This invention drives one side of the threaded rod to rotate by rotating a knob, and through the meshing transmission of gears and gear rings, drives the other side of the threaded rod to rotate synchronously, thereby driving the lifting ring to move vertically. Then, through the insert plate, the movable piece moves, adjusting the distance between the movable piece and the slider, thereby changing the compression degree of the spring at the bottom of the movable piece. This allows the equipment to provide the most suitable flattening force for fabrics with different elasticity or thickness, improving the detection accuracy of different clothing fabrics.

[0028] 3. This invention uses a filter screen to intercept lint. The airflow drives the impeller to rotate, and the impeller drives the curved plate and the brush at the bottom to rotate via a rotating rod. This sweeps the lint on the top of the filter screen into the collection box through the window, ensuring smooth airflow for detection. At the same time, it prevents lint from entering the flow meter and air pump, extending the service life of the equipment and reducing the maintenance frequency. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to Figures 1-8.

[0032] This invention provides a multi-station garment fabric air permeability testing device, including a base 1, a support plate 5 mounted on the top of the base 1, a fixing mechanism 2 on the top of the support plate 5, the fixing mechanism 2 including multiple support cylinders 21, the multiple support cylinders 21 being fixedly connected to the top periphery of the support plate 5 respectively, an adjustment mechanism 3 being provided on the upper side of the support plate 5, and a collection mechanism 4 being provided on the inner side of the support cylinders 21; a support plate 22 is fixedly connected to the top of each of the multiple support cylinders 21, the bottom of each of the multiple support cylinders 21 penetrates the support plate 5, and the top center of the support plate 5 is fixed. A hydraulic rod 23 is fixedly connected to the output end of the hydraulic rod 23, and a cross bracket 24 is fixedly connected to the output end of the hydraulic rod 23. Hollow cylinders 25 are fixedly connected to the bottom of the cross bracket 24. The hydraulic rod 23 can drive the hollow cylinders 25 to move downward through the cross bracket 24. Multiple U-shaped plates 26 are fixedly connected at equal intervals to the outer side of the hollow cylinders 25. A fixed rod 27 is fixedly connected to the inner side of the U-shaped plates 26. A slider 28 is slidably connected to the bottom of the outer side of the fixed rod 27. A movable piece 212 is slidably connected to the upper side of the outer wall of the fixed rod 27. The bottom of the movable piece 212... A spring 29 is fixedly connected, and the spring 29 can apply a pushing force to the slider 28. A connecting plate 210 is rotatably connected to the top of one side of the slider 28, and a push plate 211 is rotatably connected to the bottom of the connecting plate 210. A spring 213 is fixedly connected to the bottom of one side of the slider 28, and the other end of the spring 213 is fixedly connected to the connecting plate 210. The spring 213 can pull the connecting plate 210 to rotate downward. The fixing mechanism 2 also includes an anti-slip plate 215, which is fixedly connected to the bottom of the push plate 211. 15 can prevent the clothing fabric from slipping on the push plate 211. The bottom of the hollow cylinder 25 is fixedly connected to a sealing ring 216. The fixing mechanism 2 also includes an air pump 219, which is fixedly connected to the bottom of the support plate 5. The input end of the air pump 219 is connected to an air pipe 218. The air pump 219 can create a negative pressure environment inside the support cylinder 21 through the air pipe 218. The bottom of the support cylinder 21 is connected to a flow meter 220, and the bottom of the flow meter 220 is connected to the air pipe 218. The flow meter 220 can measure the airflow.Specifically, when multiple sets of garment fabrics need to be tested for breathability, the individual fabrics to be tested are first laid flat on the top surface of the support plate 22 at their respective workstations. Then, the hydraulic rod 23 is activated, and the output end of the hydraulic rod 23 drives the cross bracket 24 below to move downwards synchronously. The movement of the cross bracket 24 further drives the hollow cylinders 25 connected to each workstation to descend vertically. During the descent, the hollow cylinders 25 drive the outer U-shaped plate 26 and the connecting plate 210 to move downwards synchronously, so that the anti-slip plate 215 at the bottom of the push plate 211 contacts the upper surface of the garment fabric first, and the anti-slip plate 215 contacts the upper surface of the garment fabric earlier than the sealing ring 216 at the bottom of the hollow cylinder 25. When the materials come into contact, as the hollow cylinder 25 continues its downward feeding trend, the obstructed push plate 211 will push the connecting plate 210 to rotate around the slider 28, thereby stretching the spring 213 and causing deformation. At the same time, the rotation trajectory of the connecting plate 210 will cause the push plate 211 to move. The push plate 211 generates frictional tension on the contacting fabric through the anti-slip plate 215 at its bottom. Multiple push plates 211 distributed around the hollow cylinder 25 will synchronously perform a radial centrifugal diffusion motion, thereby causing the garment fabric below to spread out and flatten in all directions, eliminating the tightness difference and surface wrinkles caused by the natural placement of the fabric, and ensuring that the fabric at all workstations can be evenly distributed. Under completely uniform physical tension conditions, the breathability test is conducted to ensure the consistency of data from multiple parallel testing stations. When the fabric is fully stretched to a taut state, the reverse support pressure exerted by the taut fabric on the push plate 211 will be greater than the initial thrust exerted by the spring 29 on the slider 28. As the hollow cylinder 25 continues to press down, the push plate 211 will push the slider 28 upward along the fixed rod 27 via the connecting plate 210, thereby compressing the spring 29 to absorb excess travel and ensuring that the fabric is not damaged due to overstretching. At this time, the sealing ring 216 at the bottom of the hollow cylinder 25 descends to the position of contact with the fabric surface, and then works with the support plate 22 to hold the fabric edge... The sealing ring 216 is firmly pressed and fixed, and its downward pressing action effectively eliminates the tiny gaps between the garment fabric and the support plate 22, preventing air leakage from affecting the accuracy of the final test. After the fabric is fixed and the formal testing phase begins, the air pump 219 is started. The air pump 219 continuously draws air from inside the support cylinder 21 through the connected air pipe 218, creating a stable negative pressure environment inside the support cylinder 21. Outside air, under the pressure difference, passes through the fabric being tested and enters the inside of the support cylinder 21. When the airflow passes through the flow meter 220 at the bottom, the real-time airflow rate is accurately calculated, and the fabric's air permeability index is calculated based on the flow data.

[0033] The adjusting mechanism 3 includes multiple threaded rods 31, which are rotatably connected to the top of the left and right sides of the hollow cylinder 25. A lifting ring 32 is threadedly connected to the outer side of each threaded rod 31. Rotation of the threaded rod 31 causes the lifting ring 32 to move vertically. Multiple insert plates 33 are fixedly connected at equal intervals to the bottom of the lifting ring 32. The bottom of each insert plate 33 passes through a U-shaped plate 26 and contacts a movable plate 212. The lifting ring 32 can drive the movable plate 212 to move via the insert plates 33. A gear 34 is fixedly connected to the upper side of the outer wall of each threaded rod 31. A toothed ring 35 is rotatably connected to the top of the hollow cylinder 25. The toothed ring 35 meshes with a gear 34. When one threaded rod 31 rotates, the transmission action between the toothed ring 35 and the gear 34 drives the other threaded rod 31 to rotate. The adjustment mechanism 3 also includes a knob 36, which is fixedly connected to the top of the threaded rod 31. The knob 36 facilitates the operator to rotate the threaded rod 31. Specifically, when using this testing equipment to test fabrics of different materials or thicknesses, the differences in the physical properties of the fabrics can lead to complete stretching and flattening. The required critical tensile forces are not the same. To accommodate this difference, the operator can rotate either of the knobs 36 on either side of the hollow cylinder 25. The rotation of the knob 36 will directly drive the threaded rod 31 to rotate. When the threaded rod 31 rotates, it will mesh with the gear 34 and the gear ring 35, thereby driving the gear 34 and the threaded rod 31 on the other side to rotate synchronously. Driven by the synchronous rotation of the threaded rods 31 on both sides, the lifting ring 32 will move vertically along the outer wall of the hollow cylinder 25. During the movement, the lifting ring 32 drives the movable piece 212 below to slide synchronously on the fixed rod 27 through the bottom fixed insert plate 33. By changing the relative vertical distance between the movable piece 212 and the slider 28, the pre-compression of the spring 29 at the bottom of the movable piece 212 can be directly changed, thereby adjusting the magnitude of the pressing force applied by the spring 29 to the slider 28. This allows for the setting of matching flattening force for different types of clothing fabrics, ensuring that the fabric is fully stretched while avoiding damage, and improving the adaptability and accuracy of the testing equipment for different types of clothing fabrics.

[0034] The collection mechanism 4 includes a filter screen 41, which is fixedly connected to the inside of the support cylinder 21. A rotating rod 42 is rotatably connected to the bottom of the filter screen 41, and an impeller 43 is fixedly connected to the bottom of the rotating rod 42. When the airflow passes through the support cylinder 21, it will drive the impeller 43 to rotate. A curved plate 44 is fixedly connected to the top of the rotating rod 42 through the filter screen 41. When the impeller 43 rotates, it can drive the curved plate 44 to rotate through the rotating rod 42. Brush bristles 45 are provided at the bottom of the curved plate 44. The curved plate 44 can drive the brush bristles 45 to move and thus clean the lint. A window 46 is provided in the upper middle part of the inner wall of the support cylinder 21. A collection box 47 is fixedly connected to the outer side of the support cylinder 21. The window 46 is connected to the collection box 47, and the bristles 45 can fall into the collection box 47 through the window 46. The collection mechanism 4 also includes a box cover 48, which is rotatably connected to one side of the collection box 47. Opening the box cover 48 allows the lint in the collection box 47 to be cleaned. Specifically, during the air permeability test, because the inside of the support cylinder 21 is in a negative pressure suction state for a long time, the fine bristles falling off the fabric surface... Floss and impurities are drawn into the support cylinder 21 by the airflow. The filter screen 41 blocks the incoming lint, effectively preventing it from passing through the support cylinder 21 and entering the flow meter 220 and the air pump 219. This avoids lint accumulation damaging the components of the detection equipment. When the high-speed airflow passes through the support cylinder 21 and flows downward, it impacts and drives the impeller 43 to rotate. The continuous rotation of the impeller 43 drives the upper curved plate 44 to rotate synchronously through the centrally connected rotating rod 42, which in turn drives the bristles 45 installed on the bottom surface of the curved plate 44 to move through the airflow. The filter screen 41 performs a circular sweeping motion, sweeping away the lint that has accumulated on the top of the filter screen 41 and cleaning it out through the side window 46. The cleaned-out lint will naturally fall into the outer collection box 47 after passing through the window 46, preventing the lint from accumulating more and more on the top of the filter screen 41 and increasing the air intake resistance. This ensures the normal flow of the detection airflow and the stability of the test data. When a large amount of lint accumulates inside the collection box 47, the side cover 48 can be opened to easily clean and remove the waste lint collected inside the collection box 47.

[0035] The fixing mechanism 2 also includes a stop 214, which is fixedly connected to one side of the slider 28. The outer side of the stop 214 is in contact with the connecting plate 210. Specifically, the stop 214 can limit the rotation angle of the connecting plate 210, prevent the connecting plate 210 from rotating to a vertical state, and prevent the connecting plate 210 from getting stuck when it moves down.

[0036] The fixing mechanism 2 also includes multiple guide rods 217, which are fixedly connected to the top periphery of the support plate 5, and the top of the guide rods 217 penetrates the cross bracket 24; specifically, the guide rods 217 can guide the movement of the cross bracket 24 and prevent the cross bracket 24 from deviating during the lifting and lowering process.

[0037] Working principle: When testing the breathability of clothing fabrics, multiple fabrics are first placed on top of the support plate 22 at their respective workstations. Then, the hydraulic rod 23 is activated, causing the cross bracket 24 to move downwards. This, in turn, moves the hollow cylinders 25 at multiple workstations downwards. The hollow cylinders 25 then move the U-shaped plate 26 downwards, which in turn moves the connecting plate 210 downwards. This causes the anti-slip plate 215 at the bottom of the push plate 211 to contact the clothing fabric. The anti-slip plate 215 contacts the fabric before the sealing ring 216 at the bottom of the hollow cylinder 25. As the hollow cylinder 25 continues to move downwards, the push plate 211 pushes the connecting plate 210 to rotate around the slider 28, thereby stretching the second spring 213. Furthermore, when the connecting plate 210 rotates, it drives the push plate 211 to move. The push plate 211 then stretches the fabric through the anti-slip plate 215. During this process, multiple push plates 211 on the outside of the hollow cylinder 25 will perform radial centrifugal motion, thereby causing the garment fabric to unfold, eliminating differences in fabric tension and wrinkle interference, ensuring that the fabric at all workstations is under the same physical tension state for breathability testing, and ensuring the consistency of multi-workstation testing. When the fabric is fully unfolded, the pressure exerted by the fabric on the push plate 211 is greater than the pushing force of the spring-29 on the slider 28. At this time, when the hollow cylinder 25 moves downward, the push plate 211 will push the slider 28 upward through the connecting plate 210, thereby compressing the spring-29, so that the fabric will not... When excessive stretching occurs, the hollow cylinder 25 causes the sealing ring 216 to come into contact with the fabric, thus fixing the fabric to the top of the support plate 22. The downward pressure of the sealing ring 216 compresses the fabric, preventing gaps between the fabric and the support plate 22 that could affect testing accuracy. During testing, the air pump 219 is activated, drawing air from the support cylinder 21 through the air pipe 218, creating a negative pressure environment within the cylinder. Air then passes through the fabric and enters the inside of the support cylinder 21. The flow rate is measured by the flow meter 220, providing data on the fabric's breathability. Furthermore, when testing different fabrics using the same equipment, the degree of stretching varies. The required pulling force for the display is also different. At this time, one of the knobs 36 on both sides of the hollow cylinder 25 will rotate. The knob 36 will drive the threaded rod 31 on one side to rotate. When the threaded rod 31 on one side rotates, it will drive the threaded rod 31 on the other side to rotate through the transmission action of the gear 34 and the gear ring 35. When the threaded rods 31 on both sides rotate synchronously, they can drive the lifting ring 32 to move vertically. When the lifting ring 32 moves, it can drive the movable piece 212 to move through the insert plate 33. By controlling the distance between the movable piece 212 and the slider 28, the amount of pushing force applied by the spring 29 at the bottom of the movable piece 212 to the slider 28 can be adjusted, thereby stretching out clothing fabrics of different materials and improving the detection accuracy of clothing fabrics.Finally, during the testing process using the testing equipment, because the support cylinder 21 is under negative pressure, lint from the fabric will enter the support cylinder 21. At this time, the filter screen 41 can block the lint, thus preventing it from entering the flow meter 220 and air pump 219 through the support cylinder 21, thereby avoiding damage to the testing equipment. When the airflow passes through the support cylinder 21, it will drive the impeller 43 to rotate. When the impeller 43 rotates, it can drive the curved plate 44 to rotate through the rotating rod 42, which in turn drives the bristles 45 to move and clean the lint on the top of the filter screen 41 out through the window 46. The lint will fall into the collection box 47 through the window 46, preventing lint from accumulating on the top of the filter screen 41 and ensuring normal airflow. When a lot of lint accumulates in the collection box 47, the box cover 48 can be opened to clean the lint in the collection box 47.
