Description

Technical Field

[0001] The invention relates to the technical field of new material diapers, and in particular to an air permeability detection system for new material diapers. Background Art

[0002] New material diapers refer to diapers made of innovative materials that break through the limitations of traditional materials and have higher performance or environmentally friendly properties. For example, super absorbent resin is used to replace traditional petroleum-based SAP, which has better water absorption performance and is degradable, or nano-scale fibers are used to improve water absorption and breathability and reduce bacterial growth. These products have undergone technical upgrades in absorbency, breathability, comfort and environmental protection. When producing new material diapers, their breathability needs to be tested.

[0003] For example, the invention with publication number CN112378833B discloses an intelligent diaper air permeability detection system. The invention can measure the air permeability of the diaper by turning on the exhaust fan to draw the air above the diaper to the bottom. The cloth strip on the mesh plate can detect whether the air is flowing, and can intuitively see whether the diaper is breathable. The heating rod can heat the diaper to simulate the baby's skin temperature, which improves the accuracy of the detection result. The through-hole grooves symmetrical on both sides of the arc plate can make the wind evenly distributed through the bottom of the diaper. The cloth strip can swing the air, further improving the uniformity of air flow and increasing the accuracy of the air permeability detection result. However, during the detection process, it is inconvenient to accurately define the pressure difference on both sides of the diaper and to detect the air permeability, so it is not convenient to intuitively calculate the air permeability of the diaper.

[0015] 1. The present invention uses a fan to filter air and allow it to enter the pressure-stabilizing cover to form a pressure difference, which can drive the piston plate in the measuring cylinder to move to measure the air permeability. The transparent measuring cylinder and scale design are convenient for direct reading. The pressure-stabilizing chamber is equipped with a spring sealing plug to automatically release pressure to maintain constant pressure. At the same time, the orifice plate structure ensures that the air flow is uniform and stable. Therefore, in the actual detection process, since the air permeability usually refers to the volume of gas passing through a unit area of ​​material per unit time under a specific pressure difference, in this device, the pressure, time and area during measurement are the same. Therefore, the air permeability of the new material diaper sample can be accurately measured by observing and recording the position of the piston plate, so that accurate air permeability data can be obtained without a sensor, which greatly reduces equipment costs and improves the production efficiency of the enterprise.

[0016] 2. The present invention adopts a worm gear transmission structure to control the clamping mechanism, and realizes uniform force and self-locking fixation of the clamping ring through the linkage of a gear set. Equidistantly distributed limit blocks ensure uniform pressure on the clamping surface and improve the sealing of the sample. A transparent observation tube and a waterproof breathable membrane are specially arranged to detect leakage. The pre-set red solution can intuitively display sealing failure. Double protection prevents gas leakage from affecting the detection accuracy, and the self-locking characteristics of the worm gear ensure the clamping stability.

[0017] 3. The present invention utilizes a counterweight balancing system to improve detection sensitivity. The slide seat and the counterweight block form a dynamic balance through the rope, which effectively offsets the movement resistance of the piston plate. The slide rod guide ensures the stability of the slide seat displacement. After detection, the balance state is quickly released through the magnetic adjustment block, and the counterweight system automatically completes the reset operation, avoiding the time-consuming and laborious manual lifting of heavy objects. At the same time, magnetic fixation realizes rapid reorganization and installation, which significantly improves the convenience of equipment operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] See also Figure 1 , Figure 5 and Figure 6 , the present invention provides a technical solution: A new material diaper air permeability detection system includes a detection platform 1 and a detection component 5. A bracket 2 is arranged on the top of the detection platform 1, and a fixing clamp ring 3 is arranged in the middle of the bracket 2. The detection component 5 is arranged in the middle of the detection platform 1. The detection component 5 includes a fan 501. The fan 501 is arranged at the bottom of the detection platform 1, and a filter cover 502 is arranged at one end of the fan 501, and a pressure stabilizing cover 503 is connected to the other end of the fan 501. A bracket 504 is arranged at the bottom of the pressure stabilizing cover 503, and the bracket 504 is U-shaped, and the middle of the bracket 504 is A vertical rod 505 is slidably connected, a sealing plug 506 is fixed on the top of the vertical rod 505, and the sealing plug 506 is truncated, and the sealing plug 506 matches the bottom opening of the voltage-stabilizing cover 503, a compression spring 507 is sleeved on the outer side of the vertical rod 505, and the upper and lower ends of the compression spring 507 are respectively fitted with the bottom of the sealing plug 506 and the middle top surface of the bracket 504, an orifice plate 508 is arranged inside the voltage-stabilizing cover 503, a measuring cylinder 509 is fixedly connected to the top of the fixed clamp ring 3, and a piston plate 510 is slidably connected to the inside of the measuring cylinder 509.

[0021] After the new material diaper sample is clamped and positioned, the fan 501 is started, and the external air will enter the pressure-stabilizing cover 503 under the filtration of the filter cover 502. At this time, under the limiting action of the bracket 504, the compression spring 507 pushes the sealing plug 506 to form a seal with the pressure-stabilizing cover 503, causing the internal air pressure to increase. At the same time, the top of the measuring cylinder 509 is connected to the outside air, so the air pressure at the top of the new material diaper sample will be the same as that of the outside. The airflow will flow through the new material diaper sample into the measuring cylinder 509 due to the pressure difference, thereby driving the piston plate 510 to move up. The measuring cylinder 509 is transparent and has scales on the outside to facilitate observation of the position of the piston plate 510. Therefore, the gas flow through the new material diaper sample can be obtained based on the upward movement distance of the piston plate 510. Volume, and when the internal pressure of the pressure-stabilizing cover 503 is too high, the airflow will also squeeze the sealing plug 506, causing the compression spring 507 to be compressed, and the sealing plug 506 will be separated from the pressure-stabilizing cover 503, so that the pressure can be automatically released. At the same time, the orifice plate 508 can make the airflow blow evenly to the new material diaper sample, and can also play a role in stabilizing the pressure. Therefore, in the actual detection process, since the air permeability usually refers to the volume of gas passing through a unit area of ​​material per unit time under a specific pressure difference, in this device, the pressure, time and area during measurement are the same. Therefore, the air permeability of the new material diaper sample can be accurately measured by observing and recording the position of the piston plate 510. At the same time, the present application does not require a variety of sensors, which is conducive to saving equipment costs and improving the production efficiency of the enterprise.

[0022] See also Figures 1 to 4 A clamping assembly 4 is connected to one side of the bracket 2.

[0023] In some embodiments, the clamping assembly 4 includes a worm 401, one side of the bracket 2 is rotatably connected to the worm 401, and a worm wheel 402 is meshed on the outer side of one end of the worm 401, a rotating shaft 403 is fixed inside the worm wheel 402, and the rotating shaft 403 is rotatably connected to the detection platform 1, and a driving gear 404 is arranged on the outer side of the lower end of the rotating shaft 403, and a gear ring 405 is meshed on one side of the driving gear 404, and the teeth of the gear ring 405 are distributed in a fan shape, and a first limit block 406 is arranged on the top of the gear ring 405, and a second limit block 407 is slidably connected to one side of the first limit block 406, and a movable clamp ring 408 is fixed on the top of the second limit block 407, and the first limit block 406 is in a right-angle trapezoidal shape. The first limit blocks 406 are equidistantly distributed around the bottom of the gear ring 405, and the first limit blocks 406 correspond one to one with the second limit blocks 407. The inner lining ring 409 is slidably connected to the inside of the movable clamp ring 408, and the outer lining ring 409 is slidably connected to the guide block 410, and the guide block 410 is fixedly connected to the movable clamp ring 408. The detection platform 1 is rotatably connected to the gear ring 405, and the inner lining ring 409 is fixedly connected to the detection platform 1. An annular groove 411 is provided at the bottom of the fixed clamp ring 3, and an observation tube 412 is arranged on the top of the fixed clamp ring 3, and the interior of the annular groove 411 is connected to the interior of the observation tube 412, and a waterproof and breathable membrane 413 is provided inside the observation tube 412.

[0024] The specific operation is as follows: first, flatten the new material diaper sample that is fully absorbed with physiological saline and place it between the fixed clamp ring 3 and the movable clamp ring 408, then rotate the worm 401 to drive the worm wheel 402 to rotate, thereby driving the ring gear 405 to rotate through the rotating shaft 403 and the driving gear 404. At this time, the inner lining ring 409 will limit the moving direction of the movable clamp ring 408 through the guide block 410, so that it can only move vertically. Therefore, when the ring gear 405 drives the first limit block 406 to squeeze the inclined surface of the second limit block 407, the movable clamp ring 408 will move up to clamp the new material diaper sample. At the same time, the first limit block 406 and the second limit block 407 are equidistantly distributed on the circumference, which can be more even when the force is applied, which is conducive to improving the clamping The sealing performance after clamping is improved, and the self-locking performance of the worm 401 and the worm wheel 402 is utilized to increase the stability after clamping, and the teeth on the gear ring 405 are distributed in a fan shape, so only a small rotation angle is required to complete the clamping operation, thereby improving the efficiency during clamping. In the subsequent detection process, once part of the airflow leaks from between the fixed clamp ring 3 and the movable clamp ring 408, it can flow into the observation tube 412 through the annular groove 411. Since a striking red solution is pre-arranged above the waterproof breathable membrane 413, and the top of the waterproof breathable membrane 413 is connected to the external atmosphere, the sealing performance of the fixed clamp ring 3 and the movable clamp ring 408 after clamping can be observed by observing whether there is any bubble leakage, thereby avoiding affecting the subsequent detection accuracy due to gas leakage.

[0025] See also Figure 6 to Figure 7 A resistance reduction component 6 is provided on the top of the measuring cylinder 509, and the resistance reduction component 6 includes a dustproof plate 601, a dustproof plate 601 is arranged on the top of the measuring cylinder 509, and a pulley seat 602 is arranged on the top of the dustproof plate 601, and a rope 603 is sleeved on the outer side of the pulley seat 602, a first counterweight block 604 is fixed to one end of the rope 603, and the first counterweight block 604 is fixedly connected to the piston plate 510, a slide seat 605 is arranged on the other end of the rope 603, and a slide rod 606 is slidably connected to one end of the slide seat 605, and the slide rod 606 is fixedly connected to the measuring cylinder 509, a second counterweight block 607 is arranged on one side of the slide seat 605, and a limiting rod 608 is arranged on the other side of the slide seat 605, and a magnet 609 is fixed to one end of the limiting rod 608, an adjusting block 610 is sleeved on the outer side of the limiting rod 608, and the adjusting block 610 is magnetically connected to the magnet 609.

[0026] The specific operation is as follows: the slide 605 pulls the piston plate 510 through the rope 603, and uses the first counterweight block 604 and the second counterweight block 607 to counterweight the two ends of the rope 603, thereby reducing the friction resistance when the piston plate 510 moves upward and forming a balance. Therefore, when the airflow enters the inside of the observation tube 412, it will be easier to drive the piston plate 510 to move upward, and use the slide bar 606 to guide the slide block 605 to improve the stability during the movement. After the test, when the piston plate 510 moves to the upper part of the measuring cylinder 509, the slide The seat 605 will move to the lower end of the slide bar 606. At this time, when resetting, you only need to pull out the adjustment block 610 with force to break the balance at both ends of the rope 603. The first counterweight block 604 will drive the slide seat 605 to automatically slide down and reset. There is no need to support the heavier slide seat 605 and wait for the piston plate 510 to slide down slowly. After the piston plate 510 is reset, the adjustment block 610 is put on the outside of the limit rod 608. At this time, the magnet 609 will be adsorbed with the adjustment block 610, thereby quickly fixing the adjustment block 610, making it more labor-saving and convenient to reset the piston plate 510.

[0027] When the air permeability detection system of the present application is used to detect new material diapers, the new material diaper sample that is fully absorbed with physiological saline is first flattened and placed between the fixed clamp ring 3 and the movable clamp ring 408, and then the worm 401 on the side of the bracket 2 is rotated to drive the worm wheel 402 to rotate, thereby driving the ring gear 405 to rotate through the rotating shaft 403 and the driving gear 404. At this time, the inner lining ring 409 will limit the moving direction of the movable clamp ring 408 through the guide block 410, so that it can only move vertically. Therefore, when the ring gear 405 drives the first limit block 406 to squeeze the inclined surface of the second limit block 407, the movable clamp ring 408 will move up to clamp the new material diaper sample; Secondly, the fan 501 is started, and the external air will enter the pressure-stabilizing cover 503 under the filtration of the filter cover 502. At this time, under the limiting effect of the bracket 504, the compression spring 507 pushes the sealing plug 506 to form a seal with the pressure-stabilizing cover 503, resulting in an increase in the internal air pressure. When the internal pressure of the pressure-stabilizing cover 503 is too high, the airflow will also squeeze the sealing plug 506, causing the compression spring 507 to compress, and the sealing plug 506 will separate from the pressure-stabilizing cover 503, so that the pressure can be automatically released. At the same time, the orifice plate 508 can make the airflow evenly blow to the new material diaper sample, and can also play a role in stabilizing the pressure; Next, since the top of the measuring cylinder 509 is connected to the outside air, the slide 605 will pull the piston plate 510 through the rope 603, and the first counterweight block 604 and the second counterweight block 607 are used to counterweight the two ends of the rope 603, thereby reducing the friction resistance when the piston plate 510 moves upward. The airflow will flow into the measuring cylinder 509 through the new material diaper sample due to the pressure difference, thereby driving the piston plate 510 to move upward. In this process, the slide rod 606 is used to guide the clamping block of the slide 605 to improve the stability during the movement; Then, the volume of gas passing through the new material diaper sample can be obtained according to the upward movement distance of the piston plate 510. Therefore, in the actual detection process, since the air permeability usually refers to the volume of gas passing through a unit area of ​​material per unit time under a specific pressure difference, in this device, the pressure, time and area during the measurement are the same. Therefore, the air permeability of the new material diaper sample can be accurately measured by observing and recording the position of the piston plate 510. In addition, during the detection process, once part of the airflow leaks from between the fixed clamp ring 3 and the movable clamp ring 408, it can flow into the observation tube 412 through the annular groove 411. Since a striking red solution is pre-set above the waterproof breathable membrane 413, and the top of the waterproof breathable membrane 413 is connected to the external atmosphere, the sealing performance of the fixed clamp ring 3 and the movable clamp ring 408 after clamping can be observed by observing whether there is any bubble leakage; Finally, after the detection, when the piston plate 510 moves to the upper part of the measuring cylinder 509, the slide 605 will move to the lower end of the slide rod 606. At this time, when resetting, you only need to pull out the adjustment block 610 with force to break the balance at both ends of the rope 603, and the first counterweight block 604 will drive the slide 605 to automatically slide down and reset. There is no need to support the heavier slide 605 and wait for the piston plate 510 to slide down slowly. After the piston plate 510 is reset, the adjustment block 610 is put on the outside of the limit rod 608. At this time, the magnet 609 will be adsorbed on the adjustment block 610, thereby quickly connecting the adjustment block 610.
